Dealing in metal from Papua could break UK law because of environmental impact of mining it
Campaigners have warned the world’s largest metals market, the London Metal Exchange (LME)
that it could be breaking the law by allowing the trading of copper from one of the world’s most controversial mines
The way the metal is produced at the Grasberg mine in the highlands of Papua, Indonesia
is so environmentally destructive it would be illegal almost anywhere else in the world
Yet products containing copper from the Grasberg mine such as cathodes are sold every day on the London exchange
which describes itself as “the world’s centre for industrial metals trading” and from there they go into the supply chains crisscrossing the globe
Situated in the western highlands of the island of New Guinea
in the midst of the world’s third-largest remaining rainforest
the Grasberg mineral district is one of the world’s most important sources of copper and gold
But since its development in the late 1960s, the mine has been allowed to use a so-called “riverine tailings management system”, through which it disposes of an estimated 200,000 tonnes of mining waste a day directly into the headwaters of the Ajkwa river delta
Ore from the mine is ground down to the consistency of fine sand and mixed with water to produce a slurry treated with chemicals that make the gold
copper and silver minerals within rise to the top
After the commercial minerals are skimmed off
the remaining finely ground rock particles – known as tailings – are dumped into a river next to the site
from where they flow downstream into the Ajkwa delta flood plain
says it has “designed and constructed a system of levees to manage the deposition of what will ultimately be about 3bn tonnes of tailings” by the end of the mine’s life
People indigenous to Papua claim their communities have been racked with poverty
oppression and environmental degradation since the mine began operations in 1973
An analysis of the mine’s tailings waste published in 2020 found it contained contaminants including arsenic
and a 2016 study in Nature found that the sheer volume of the waste was leading to “forest inundation and degradation of water bodies critical to Indigenous peoples”
One tribal chief from the area said in 2016 that tailing sediment from the mine had raised the riverbed by his village
oysters and shrimp on which his people’s diet and economy are traditionally based
PTFI told the Guardian that managing the tailings process safely and effectively was one of their top environmental priorities
“The tailings management system from the Grasberg mine has complied with the AMDAL (Environmental Impact Assessment)
and it has been operating for almost 30 years
We continue to demonstrate through external reviews that the system is the most environmentally sound approach for tailings management at Grasberg
“We are committed to responsible production
integrating leading international environmental standards and technologies at all our operations
On Monday, campaigners from the London Mining Network (LMN) and the Global Legal Action Network (GLAN) wrote to the LME and its regulator
to warn that trading copper produced at Grasberg could amount to money laundering
They say that disposing of the mining waste in this way would constitute a serious offence if it took place in the UK
and so copper produced at the mine could be considered to be “criminal property” under the Proceeds of Crime Act (POCA)
“The London Metal Exchange is the world centre for metals and critical minerals trading,” said Stéphanie Caligara
“As humanity’s reliance on metals like copper intensifies in the pursuit of the ‘green transition’
the exchange has a legal duty to ensure that the metals traded on its exchange are not produced on the backs of environmental crimes
“It also has a critical role in safeguarding the integrity of global supply chains
the FCA must investigate any suspicion of laundering of proceeds of crime trading on the exchange.”
the campaigners tell LME that it is obliged to inform the National Crime Agency of any suspected money laundering taking place on its exchange
Last year they attempted to judicially review the trade in Grasberg copper on the platform
but a judge told them they must raise a complaint directly with the LME and the FCA before that kind of legal action could be taken
Caligara said: “GLAN has identified similar patterns with mining corporations operating in Brazil
Guinea and the Russian Federation to name only a few and trading their products on the London Metal Exchange
GLAN and LMN’s action might force these companies to revisit too the way they produce metals in these countries
This in turn could lead to reduced environmental harm linked to mining and drastic improvement of the livelihood of communities affected by these operations.”
According to its website
the LME says that since the beginning of 2024 any products listed on its exchange must comply with responsible sourcing requirements outlined by the Organisation for Economic Co-operation and Development and the International Organization for Standardization
It is understood that even if the exchange had raised concerns over the production of any product it lists
it would not be able to make those concerns public
A spokesperson for the exchange said: “The LME takes its regulatory obligations seriously
and has appropriate measures in place to comply with such obligations

Freeport McMoRan is set to resume Indonesian copper exports
thanks to a new license allowing shipments from its massive Grasberg mine
Freeport McMoRan's return to export comes after their license lapsed in December
This shift is essential post-fire damage at their Manyar smelter
compelling the company to find new ways to satisfy global demand
Although Indonesia's policies encourage local mineral processing
backing Freeport's exports shows a flexible approach to balancing domestic goals with global market requirements
The initial shipments to China are due by late February
promising to alleviate the copper concentrate shortage
have dropped to an unprecedented negative $12.5 per ton
For markets: Copper flows to calm the storm
The restart of Freeport McMoRan's copper exports should stabilize global supply chains
especially aiding smelters impacted by limited concentrate availability
This move is expected to influence pricing and alleviate treatment charge levels
making it a key focus for stakeholders in the copper and broader metals market
The bigger picture: Global demand meets local policy
Indonesia's decision to extend an export license to Freeport McMoRan highlights the intricate balance between national resource management and international economic demands
impacting not just copper but many commodities crucial to infrastructure and technology sectors worldwide

The Indonesian government has agreed to allow copper miner PT Freeport Indonesia to resume exports of copper concentrate until repairs at its smelter are completed
Energy and Mineral Resources Minister told reporters on Friday
The government had previously given Freeport an exemption until the end of 2024 from its ban on exports of copper concentrate
as the company was ramping up production at its new Manyar smelter
Minister Bahlil Lahadalia said the government had decided to allow exports by Freeport but would impose export duties on the shipments as a penalty
He said the government was currently calculating the export volume it would allocate to Freeport
Freeport Indonesia could not immediately be reached for comment

Freeport-McMoRan has requested approval from the Indonesian government to permit the export of copper concentrate in 2025 "until the required repairs of its new smelter following the October 2024 fire incident and full ramp-up are complete."
Current regulations in Indonesia prohibit exports of copper concentrate as of January 1
Freeport-McMoRan's fire-hit giant Manyar copper smelter in East Java, Indonesia
is reportedly expected to remain offline until the July-September quarter of this year and spend the following six months in ramp-up mode before returning to normal operation
The copper smelter – among the world's largest with an output capacity of 650,000t of copper cathodes and 50-60t of gold – was launched in June 2024
and was intended to reach full capacity before the end of 2024.
Then came the fire on October 14
It occurred in a gas cleaning facility designed to remove particles from gases before conversion to sulphuric acid.
Based on discussions with the Indonesian government to date
that it expects to recommence exports of copper concentrate during the first quarter of 2025 and
would be required to pay a 7.5% export duty on copper concentrate exports during 2025
Freeport's fourth-quarter profit was helped by higher copper prices
the company said in its fourth-quarter results
Operating income for the fourth quarter was at $1.24 billion
down marginally on a year-on-year basis (Q4 2023: 1.09Blb) and 4.214Blb for the year (2023: 2.212Blb)
totalling $1.56/lb in 2024 (2023: $1.61/lb)
the net cash per pound for copper produced in Q4 2024 was higher than in Q4 2023
the company posted output of 432,000oz in Q4 2024 and sales of 350,000oz at an average realised price of $2,628/oz
Freeport-McMoRan saw an output of 1.88Moz (down from 1.99Moz in 2023) but higher year-on-year sales of 1.83Moz (2023: 1.71Moz)
Fourth-quarter 2024 copper sales of 992Mlb were slightly above the October 2024 estimate
fourth-quarter 2024 copper sales were lower than fourth-quarter 2023 sales of 1.1Blb
primarily reflecting lower ore grades and the timing of shipments at PT-FI" (the company's Indonesia smelter)
Consolidated sales volumes for the year 2025 are expected to approximate 4Blb of copper
Freeport-McMoRan is forecasting output of 850Mlb copper
Consolidated unit net cash costs (net of by-product credits) for the company's copper mines are expected to average $1.60/lb copper for the year 2025
and cost estimates and assuming average prices of $2,700/oz gold and $20/lb of molybdenum for the year 2025
Freeport-McMoRan said that it is preparing data for a potential submission of an environmental impact statement by year-end 2025 on its El Abra operations in Chile to support a mill project similar to the one at Cerro Verde
indicate that the project economics would be supported using an incentive copper price of less than $4.00/lb," Freeport said

Block cave mining is the intended mining method for a number of significant copper projects under development
CRU expects block cave projects to account for over a fifth of the growth in potential copper supply by 2025
Past block caving projects have encountered a range of challenges
which have typically led to delayed ramp-up and higher costs
The current crop of caving projects should benefit from these learnings
as they are being developed by the same majors
each with decades of block caving experience
Block caving also has less flexibility to respond to any issues that may arise compared with conventional mining methods
While PT-FI has over three decades of block caving experience at Grasberg
the risk now is the scale: Grasberg is almost 100% reliant on block caves
Codelco’s Chuquicamata plans to use macroblocks up to seven times larger in area than conventional blocks
The Oyu Tolgoi block cave (company start up guidance revised (16 July
2019) to between May 2022 and June 2023) will be more than 50% larger than any other block cave Rio Tinto has previously operated and it is in a relatively weak and heavily faulted rock mass
the Resolution block cave will be the deepest block cave in the world at around 2km and one of the hottest mines at 76° to 82° Celsius
Depletion of near surface orebodies sparks interest in underground cave mining methods
Block caving is an underground mining technique that allows for the bulk extraction of large
relatively lower grade ore deposits with substantial vertical dimension
The technique involves undercutting a large section of ore by drilling and blasting
which then intentionally starts to collapse under gravity
The broken ore falls into a series of pre-constructed funnels
The ore is then removed from access tunnels underneath the caving rock mass
The interest in cave mining is being fuelled by the depletion of near surface orebodies
relatively high production rates and low operating costs
open pits often have a continuation of the orebody below their economic depth
the extraction of which would not be economic using conventional underground mining methods
While the capital cost for block caving is significant – typically over US$5 bn for current large-scale block caves – operating costs are significantly lower than for traditional underground mining methods
are a fraction of the cost of other underground mining methods
largely driven by high production rates that for some of the new “supercave” projects are expected to reach 100,000 tonnes of ore per day
The lower operating cost of underground block cave mining can be comparable with higher cost open pit operations and can either be a viable alternative to develop a new mine or to extend the life of an existing mine
Cave mines can have a significantly smaller footprint than a comparable open-pit
since waste mined is only limited to underground infrastructure development
The minimal amount of waste is also a key permitting advantage
Other benefits include limited use of explosives to fragment the ore and reduced greenhouse emissions through minimising ore re-handling
Block cave mines are also very suitable for highly automated equipment like remote control loaders
The caving industry is now moving toward the next generation of caving geometries and scenarios where current practice and knowledge is likely to be tested
A shift is underway towards block caves at greater depths over small footprints and in competent rock-mass environments
Operators are planning higher cave columns in order to maximise profitability
These operating environments are likely to be less predictable and present new challenges
Block caving has been used for over a century
having first been applied at iron and copper mines in the US in the late 19th and early 20th centuries
it is only within the past 20 years that this method has spread more widely
There are currently approximately 18 cave mining operations in 11 countries
there are at least another 20 cave mining projects globally
in various stages of studies and development
The key players involved in the major block cave copper projects each have decades of experience in block caving
Rio Tinto has owned and operated block caves at Northparkes (copper-gold)
the experience and lessons from which will be applied in the development of its Oyu Tolgoi
PT-FI has operated block caves at Grasberg since 1980
the owner of the El Teniente NML and Chuquicamata projects
has operated block caves at El Teniente in Chile for decades
block caving is often used as a replacement mining method at an earlier open pit that has reached its economic limit
Examples include the Palabora copper-gold mine in South Africa
and the forthcoming transitions at large copper-gold mines such as Grasberg in Indonesia and Chuquicamata in Chile
Caving methods can be used with
any type of commodity since it is the geological and geotechnical context that is important
Most cave mines involve copper or diamonds
reflecting the method’s suitability for working porphyry and pipe-type deposits
Block caving is the intended mining method for several significant copper projects under development
The five largest projects that have either commenced production this year or are forecast to commission over the outlook will all use block cave mining
These are Grasberg Block Cave (GBC) which commenced in Q1
Grasberg Deep Mill Level Zone (DMLZ) – a restart
Other candidates include Rio Tinto’s Bingham Canyon
where a sequence of caving operations has been under evaluation for several years
and Rio Tinto and BHP’s Resolution Copper project in Arizona
block caves are expected to account for over a fifth of the growth in potential copper supply by 2025
increasing from 4% of current global mined copper production
to around 10% of unadjusted copper mine supply by 2025
Copper market deficits likely if block caves fall short
Our base case estimates for the global refined copper market balance are for a largely balanced market over the next three years
before turning to deficit from 2023 onwards
Our forecasts factor in relatively conservative expectations
for copper block cave project production start timing and ramp-up
if they experience any further delays or a slower than anticipated ramp-up of production
the copper market could shift to deficits sooner than we currently anticipate

High hopes that the world’s biggest gold mine will finally bring meaningful benefit to the community for which it has for decades been a source of contention have been deflated as negotiations hit a wall
(FCX) and the Indonesian government are currently hashing out the details of a long-term agreement for an extension of the company’s contract to operate the giant Grasberg gold and copper mine in Papua province
Freeport announced in August that it had agreed to divest a 51 percent stake in its Indonesian subsidiary
in which it currently holds a 90.64 percent stake
following sustained pressure by the government to reform a mining sector long seen as not doing enough to benefit local communities or contribute to the national economy
As part of broader changes to Indonesia’s mining law
the government has required that all mining firms build smelters in-country; convert their existing contracts into more flexible permits; and
for those with a foreign majority shareholder
divest a 51 percent stake in their operations to local partners within a decade of the mines coming into production
Freeport’s announcement was cheered by Indonesians
many of whom believe the country has been getting the short end of the stick in its business dealings with foreign miners
hoping the redrawn contract would finally address the impact of the company’s mining operations on the local community and improve their welfare
But as negotiations between Freeport and the government stall over the terms of the divestment
the role Papuans will play in determining the future of the mining project is once again shrouded in uncertainty
In 2016 alone, Freeport’s Indonesian operations generated $3.8 billion in revenue for the parent company. Yet despite having the world’s most profitable gold mine, Papua remains Indonesia’s poorest province, where 28 percent of the people live below the poverty line
It also has some of the worst infant mortality and literacy rates in Asia
To ensure that some of the mine’s revenues trickle down to Papuans
Energy and Mineral Resources Minister Ignasius Jonan has said that up to 10 percent of PTFI’s shares should be reserved for the Papuan government and indigenous Papuan people
But Freeport has balked at the details of the government’s plan to manage the divestment
the company expressed strong disagreement with the valuation
timing and structure put forward by the government
The government has proposed acquiring a majority stake in PTFI by the end of 2018
but Freeport wants the divestment to take place in stages over a period of several years
It also wants the first batch of shares to be offered publicly through the stock exchange
rather than allocated directly to the government
The price is another sticking point. Last year Freeport offered to divest a 10.64 percent stake in PTFI for $1.7 billion
which would give a valuation of around $8.1 billion for a 51 percent stake
Conflating FCX’s market capitalization on the New York Stock Exchange and its share of revenue from PTFI
the minister argues that the fair value for a 51 percent stake in the Indonesian operator should be $4 billion
Any hopes for immediate benefits as a result of the divestment
particularly the promised 10 percent stake for Papuans
have diminished as a result of the impasse
the national coordinator of mining sector watchdog Publish What You Pay Indonesia
said such disagreements should have been foreseen
“The contentions in the negotiation process were predictable
So any claims of victory after the divestment agreement [in August] were premature
given that there are still many details that haven’t been agreed upon,” she told Mongabay
there’s a high chance that things could still change.”
Community leaders in Papua argue they should be involved in the ongoing negotiations
regardless of whether Papuans get a share in PTFI
A group representing various indigenous tribes affected by PTFI’s mining operation met with Jonan last month to discuss the issue
“We hope we will be involved in the negotiation of the details of the agreement and that a good deal will be given be to the local people,” said Odizeus Beanal
whose highland home is where Grasberg is located
“Our hope in the future is for an agreement to be reached for indigenous people.”
They have been further displaced and marginalized by migrants from elsewhere across Indonesia drawn to the mining boomtown
Indonesia’s National Commission on Human Rights (Komnas HAM), a state-funded body, said earlier this year that PTFI had never compensated the Amungme and the Kamoro as the original stewards of the land where it operates
It characterized Freeport’s concession as a land grab
“The land that could be used to live on has been contaminated with chemicals,” Daniel Beanal, a Kamoro elder, told presidential staffers at a meeting earlier this year
I’ve never received anything from Freeport.”
Beanal argued it would be best for PTFI to cease operations
“Our aspiration is clear: to close and audit [PTFI] first. We’re not asking for a share, not even a single percent. Close the operation first, and then audit [them],” Kanunggok said
A recent report by Indonesia’s Supreme Audit Agency (BPK) identified a wide range of irregularities in PTFI’s operations and its current contract
Eleven of the issues were attributed to weak management by the government
while 10 pointed to violations of regulations by PTFI
These include indications of reckless mining
and the dumping of mining waste into rivers
An earlier review by the agency estimated the environmental damage from the company’s operations at 185 trillion rupiah ($13.7 billion)
PTFI spokesman Riza Pratama said the company manages its waste in accordance with the terms set out in the Environmental Impact Assessment (EIA) approved by the government in 1997
“We are operating in accordance with our mining contract and [mining waste processing and disposal] has been regulated in it,” he told Mongabay
if PTFI refuses to make amends for the environmental damage it has caused
The BPK also found that Freeport had used 4,536 hectares (11,208 acres) of protected forest area without obtaining the proper permits
costing the government $20 million in lost fees between 2008 and 2015
Riza declined to comment on this finding when asked by Mongabay
there is no guarantee of more environmentally sound mining operations once Freeport has relinquished a 51 percent stake in PTFI
That’s because Freeport has insisted on retaining operational control of its subsidiary until 2041
even if the government holds the majority of PTFI shares
Indonesia would have no leverage in the deal
according to PWYP Indonesia advocacy manager Aryanto Nugroho
Freeport could refuse to pay dividends to the government by saying it needs the money to cover expenses like building a smelter
which it is required to do under the new mining law
“Even if the government held the majority of shares
So there are traps like that,” Nugroho told Mongabay
The government must ensure that Freeport pays all its obligations
executive director of the Indonesian Center for Environmental Law (ICEL)
“If the obligations are paid before the takeover
But if the obligations [are held over until] after the takeover
then who would bear the burden?” Subagiyo told Mongabay
“If the government has the majority of shares
then the government would have the obligations [to pay for the damage]
Activists have urged the government to use the BPK’s findings as a basis in the negotiations with Freeport
“These problems have to be probed further and discussed during the renegotiation process of Freeport’s mining contract,” said PWYP Indonesia’s Abdullah
“Environmental problems are no less important than other problems in the renegotiation
divestment and the obligation to build smelters in Indonesia.”
President Joko Widodo has said the government is seeking a win-win solution as quickly as possible
But with neither side seeing eye to eye on the key issues
it remains unclear when the negotiations will conclude

Copper concentrate exports from Freeport-McMoRan’s unit in Indonesia will ease global shortages
but probably only briefly and if the Indonesian government allows them
including at operations owned by First Quantum
and China’s massive expansion of smelters to produce copper metal have intensified competition for concentrate since last year
A fire at PT Freeport Indonesia’s (PTFI) $3.7 billion Manyar smelter halted operations in October
PTFI is owned by Freeport and state-owned Indonesian company MIND ID
with stakes of 48.8% and 51.2% respectively
“The amounts Freeport exports depend on how long it takes to fix the problem,” said one source with knowledge of the matter
adding: “If the (Indonesian) government doesn’t grant (export) permits Freeport may have to stop mining.”
Manyar has capacity to process 1.7 million metric tons of concentrate and produce 480,000 tons of copper cathode a year
The cause of the fire is still under investigation and has yet to be corrected
Freeport McMoRan said in response to a request for comment: “PTFI has substantially completed initial damage assessments and remediation plans are in progress … PTFI currently expects to recommence start-up operations by mid-2025.”
“PTFI is working with the Indonesian government to allow continued exports of copper concentrates until full ramp-up of PTFI’s new downstream processing facilities is achieved
including seeking an increase to the permitted quota for 2024.”
Indonesia’s mining minister Bahlil Lahadalia told an industry summit last week the government had yet to decide whether to approve Freeport’s request for an export licence
Manyar was built to process copper concentrate from Freeport’s flagship Grasberg mine in Indonesia
the world’s second biggest copper-gold mine
due to the Indonesian government trying to discourage exports of concentrate
Indonesia’s government wants miners to produce metal locally to add value and boost its revenues
Industry sources said Freeport’s concentrate will not resolve the problem of shortages
which have hit the treatment and refining charges (TC/RCs) paid by miners when they sell concentrate to be turned into metal
Chilean miner Antofagasta and Jiangxi Copper recently agreed significantly lower copper concentrate processing fees for 2025
Treatment charges turned negative in April for the first time ever
meaning smelters had to pay miners to turn concentrate into metal instead of being paid
Freeport McMoRan is expected to resume shipments of copper concentrate from Indonesia this month under a new export licence after the previous one lapsed in December
according to two sources with knowledge of the matter
Indonesia has restricted raw material exports to pressure companies to refine minerals locally and add value to its exports. Freeport has local refining capacity, but is seeking to keep exporting concentrate due to a fire last October at its Manyar smelter in East Java
The miner will start loading cargoes destined for China on Friday in anticipation of receiving an export licence by month end
according to one source with direct knowledge of the matter
A shipment of copper concentrate from the company’s mine at Grasberg
the world’s second largest active copper mine
We need to start shifting it,” the first source said
Indonesia’s trade ministry said last week it would support Freeport resuming copper concentrate exports
PT Freeport Indonesia did not respond to questions about the shipments sent via text
A spokesperson said separately they expected the government would accommodate a plan to resume exports
Indonesia’s mining ministry did not respond to questions about the shipments from Reuters sent via text message
Freeport presold cargoes of copper concentrate in January with a contingent claim that the contracts will take effect only if they successfully renew their export licence
said a third source with direct knowledge of the matter
Should exports resume, it will relieve, although not reverse, a shortage of copper concentrate that has hit the profits of smelters
Treatment charges – fees paid by miners to smelters for converting raw materials into metal – stood at a negative $12.5 a ton on February 7

Grasberg minerals district includes open-pit and underground mines
It has produced 528 billion ounces of copper and 53 million ounces (Moz) of gold
including more than 432 billion ounces of copper and 46Moz of gold from the Grasberg open pit during 1990 to 2019
Extraction of ore from the Grasberg Block Cave underground mine commenced in the second quarter of 2019
which is the same ore body mined from the surface in the Grasberg open pit
The mining of the final phase of the Grasberg open pit was completed in Q4 2019 and the mine transitioned from open-pit mining to large-scale underground mining
Grasberg Block Cave is estimated to contain proven and probable reserves of 275.2 billion ounces of copper and 14.2Moz of gold as of December 2019

Freeport held a 90.64% stake in the mine operation while Rio Tinto had a 40% participating interest
the government agreed to provide a special licence to Freeport to enable the company to continue the extraction of ore until 2041
The mine stands at the collision of the Indo-Australian and the Pacific tectonic plates
Two distinct phases of intrusion have led to the production of nested coaxial porphyry ore bodies and sulphide-rich skarn at the margins
while sedimentary strata include Eocene clastic carbonate limestone with siltstones and sandstones near the base
The Dalam Diatreme (DD) forms the first intrusive stage
being highly fragmental and characterised by clasts and a matrix of dioritic composition
Mineralisation is largely disseminated and chalcopyrite dominant
having average grades of 1.2% copper and 0.5g/t gold
The second intrusive stage, the Main Grasberg Stock (MG), is composed of non-fragmental, porphyritic monzodiorites, forming a quartz-magnetite dilational stockwork with veinlet-controlled copper-gold mineralisation
with averages of 1.5% copper and 2g/t gold
which was the final intrusion and the most weakly mineralised
an underground mine and four concentrators
which forms a mile-wide crater at the surface
producing more than 67 million tonnes of ore and providing more than 75% of the mill feed in 2006
Designed to be fully mechanised, using 6.2m³ Caterpillar R1700 load-haul-dump vehicles (LHDs) at the extraction level with a truck haulage level to the gyratory crusher
the Deep Ore Zone (DOZ) block cave mine is one of the largest underground operations in the world
a second underground crusher and additional ventilation were installed to increase daily capacity to 50,000 tonnes
Ramp-up production has begun at the Deep Mill Level Zone (DMLZ) underground mine
which lies below the DOZ underground mine and to the east of the Grasberg ore body
Ore from both operations is transported by conveyor to centralized mine facilities
feeding a combined daily average total of some 225,000t of ore to the mill and 135,000t to the stockpiles
Production equipment includes 30m³–42m³ buckets
a 170-strong fleet of 70t–330t haul trucks
GPS and robotics used in the mine’s state-of-the-art slope-monitoring system
The ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. Grasberg’s milling and concentrating complex is the largest in the world, with four crushers and two giant semi-autogenous grinding (SAG) units processing a daily average of 240,000t of ore
A flotation reagent is used to separate concentrate from the ore
Slurry containing 60-40 copper concentrate is drawn along three pipelines to the seaport of Amamapare
gold and silver – is shipped to smelters around the world
The facilities at the port also include the PT Puncak Jaya coal-fired power station
Ore extraction from the Grasberg Block Cave underground mine began in H1 2019 and it is expected to produce an additional 272,000Moz of copper and 14Moz of gold over the mine life
Total undercutting in the underground mine as of July 2019 stands at 48,000m²
while the number of active production blocks increased to three
Ore extraction increased to an average of 17,000t a day in December 2019
Production is expected to subsequently increase to an average of 30,000t of ore per day in 2020
60,000t in 2021 and 130,000t in 2023 from a total of five production blocks
The ore is transported to the processing facility by a fully autonomous underground railway system

Grasberg mine in the Indonesian region has been a source of untold wealth for its owners
but local communities say it has brought poverty and oppression
a snow-covered silver crag on what was then known as Dutch New Guinea
Dozy noticed an unusual rock outcrop veined with green streaks
Samples he brought back confirmed exceptionally rich gold and copper deposits
Today, these remote, sharp-edged mountains are part of West Papua, Indonesia, and home to the Grasberg mine, one of the biggest gold mines – and third largest copper mine – in the world. Majority-owned by the American mining firm Freeport McMoRan, Grasberg is now Indonesia’s biggest taxpayer, with reserves worth an estimated $100bn (£80bn)
But a recent fact-finding mission (by the Brisbane Archdiocese’s Catholic Justice and Peace Commission) described a “slow-motion genocide” (pdf) taking place in West Papua
warning that its indigenous population is at risk of becoming “an anthropological museum exhibit of a bygone culture”
“There is no justice in this country,” whispered one indigenous villager on condition of anonymity
Dozy had not set out to find gold in 1936; his goal was to scale the region’s highest glacial peak
But his discovery sparked the interest of Freeport Sulphur – later to become Freeport Minerals Company and then
through a 1981 merger with the McMoRan Oil and Gas Company
Freeport McMoRan – whose board of directors included the well-connected Godfrey Rockefeller (serving from 1931 until the early 1980s) and Henry Kissinger (1988-1995)
indigenous tribes such as the Kamoro and the Amungme claim their communities have been racked with poverty

Clashes between the indigenous Christians – and migrant Indonesian Muslims – have also resulted in riots, fires and injuries
as the Indonesian settlers have appropriated it,” says Dr Agus Sumule
professor of agricultural socio-economics at the University of Papua
“The stresses [on indigenous people] are intense,” says Sumule
“They have been very negatively impacted.”
The compensation paid for Kamoro and Amungme land has been mainly in the form of communal benefits, such as the building of homes, schools and places of worship
“Perceptions of land rights and historic compensation claims are a continuing source of dissatisfaction and conflict in the mining area.”
Recent census data shows Papua’s GDP per capita at $3,510
compared to the Indonesian average of $2,452
Yet Papua has the highest poverty rate in the country

The scale of destitution is best observed from the highland Amungme village of Banti
The practice has devastated the environment

Crowding the length of the river and the delta wasteland
thousands of unlicensed panners shore up small sections to slow the river’s flow and dig into the thick sediment on the side

they are not evicted or controlled in any way
they claim they sell their findings to the police and military who work as security on the mine

The company’s website defends its method of disposal of tailings at Grasberg
an affiliate company: “PTFI’s controlled riverine tailings management system
which has been approved by the Indonesian government
uses the unnavigable river system in the mountainous highlands near our mine to transport tailings to an engineered area in the lowlands where the tailings and other sediments are managed in a deposition area.”
the company says that the tailings management method was chosen because studies showed the environmental impact caused by its waste material was reversible
Elsewhere on its website, the company says: “We are committed to respecting human rights. Our human rights policy requires us (and our contractors) to conduct business in a manner consistent with the Universal Declaration of Human Rights
and to align our human rights due diligence practices with the United Nations Guiding Principles on Business and Human Rights (UN Guiding Principles).”
The company also emphasises its work with indigenous people in West Papua
A 2015 Freeport McRoRan report on working towards sustainable development said: “PTFI has engaged with indigenous Papuan tribes for decades
including through numerous formal agreements to promote workforce skills training
education and basic infrastructure development … In 2015
PTFI continued to evaluate the effectiveness of alternate options for Kamoro community members whose estuary transport routes are impacted by sedimentation associated with the controlled riverine tailings management system
for route flexibility as well as additional local economic development programmes were identified as additional mitigation measures during the year.”

However, human rights violations have actually increased since Widodo took power, according to Indonesia’s Commission for the Disappeared and Victims of Violence (Kontras), which has logged 1,200 incidents of harassment, beatings, torture and killings of Papuans by Indonesian security forces since his election in 2014

For 30 years, the Arizona-based mining company has dumped millions of tonnes of mine waste directly into the Ajkwa river system where it flows into an area of lowland forest
A series of dikes and levees fail to contain the waste
means Freeport no longer holds a majority stake
its responsibility for this massive and ongoing environmental disaster remains
The mine is adjacent to Lorentz National Park, one of the largest protected areas in Southeast Asia and home to extensive biodiversity and varying ecosystems from alpine to tropical marine environments and wetlands. A study published in Nature.com in 2016 found that 138 km2 of forest has been smothered and destroyed by tailings since 1987
an area over 42 times larger than the mine itself
“Even the smallest boats are unable to pass through coastal areas that are now filled with sedimentation from mine tailings
People are forced to bath and fish in tailings laden rivers
An end to mining activity must be on the table in order to protect the beauty and biodiversity of this place
and the communities who live there.”

Fight Trump's destructive agenda all year
JAKARTA — When the Indonesian government took a controlling stake in the operator of one of the world’s richest gold mines at the end of 2018
proponents hailed the move as a historic step toward national and economic resource sovereignty
The breathless media coverage of the transaction
which saw the government take a 51 percent stake in PT Freeport Indonesia (PTFI)
previously majority-owned by Arizona-based Freeport-McMoRan
framed it as the “return” of a prized asset — the Grasberg gold and copper mine — to the Indonesian public after decades of foreign control
But little was said about the long legacy of toxic pollution from the mine
would finally bring real benefits to the indigenous people on whose land the mine sits
and who remain among the most impoverished communities in Indonesia
a 41.2 percent stake in PTFI goes to state-owned smelting company PT Indonesia Asahan Aluminium
A 10 percent stake is held by the government of Papua province
is managed 60:40 between an Inalum-controlled company and a province-owned firm
But along with ownership in one of the most coveted mines on Earth
Inalum and the Papua government have also inherited a pollution problem stemming from the mining waste
“Does the completion of the divestment deal mean that the environmental problems can be resolved
national coordinator of the Mining Advocacy Network (Jatam)
the national and provincial governments will also have to take the brunt of the fallout from the environmental damage caused by the mining operations
That fallout could amount to some $13 billion — the estimated cost of environmental damages wrought by PTFI
which identified a wide range of irregularities in the company’s operations and contract
The findings included indications of reckless mining and the disposal of mining waste into rivers
In April 2018, the Ministry of Environment and Forestry followed up with a pair of decrees ordering PTFI to overhaul its waste management plan as a prerequisite for the divestment
They included slashing toxicity levels at dumping sites and producing a strategic environmental impact assessment
under the supervision of the environment ministry
the miner had drawn up a roadmap to manage its tailings disposal through 2030
PTFI produces 167 million metric tons of tailings a day and dumps it directly into the Aghawagon and Ajkwa rivers in Papua’s Mimika district
“What we’re pushing for is how to use this amount of tailings,” said Ilyas Rasyid
the environment ministry’s inspector general
Therefore we will do research on the use of tailings.”
The audit that spurred the sanctions and decrees over PTFI’s waste management practices also found that Freeport had used 45 square kilometers (17.5 square miles) of protected forest area without obtaining the proper permits
Ilyas said the environment ministry had issued a permit
20 for 38 square kilometers (14.7 square miles) of forested land for its waste management
But he said PTFI would still have to pay fines for the previous unpermitted operation
Merah criticized this decision to simply fine the company as disappointing
mining operations in forest areas without an IPPKH permit constitute a criminal offense
with a maximum punishment of 10 years in prison
Where’s the criminal punishment?” Merah said
“There are layers of criminal acts and they’re being allowed to be washed away by paying a fine.”
saying it had failed to include civil society representatives in its discussions about PTFI’s roadmap for the mining waste management
“What exactly is the roadmap talking about
Does it comply with stringent environmental regulations
How exactly does the divestment deal mandate for environmental protection
The public deserves to know the answers to these questions because this is a public matter,” Henri said
“What we had hoped for from this acquisition was not only economic benefits but also better protection for the people of Papua,” he added
executive director of the Papuan chapter of the Indonesian Forum for the Environment (Walhi)
said taking a majority stake in PTFI didn’t necessarily mean an end to the problems arising from the mine
“Every day [PTFI] postpones rehabilitating the damaged environment
while every second the waste that enters the river poses a threat [to communities],” Maurits said
an expert in natural resources law at the University of Tarumanegara in Jakarta
said PT Inalum would be left legally and financially responsible for the environmental damage caused by PTFI’s previous activities
He said the government would have gotten a more beneficial deal had Freeport’s work permit been allowed to expire in 2021
including not paying as much for the controlling stake in PTFI
and getting a more advantageous tax arrangement after 2021
“The direct and indirect economic benefits would then be for the people and economy of Papua,” Ahmad said
In the decades since the first shipment of copper left Grasberg in 1972
the wealth of the mine has barely trickled down to the local communities
Papua remains one of the least developed and most impoverished provinces in Indonesia
with high rates of illiteracy and infant and maternal mortality
the people have been mired in conflict with the mine operator and security forces
and over the following decades have been further displaced and marginalized by migrants from elsewhere in Indonesia drawn to the mining boomtown
The National Commission on Human Rights (Komnas HAM), a state-funded body, said in March 2017 that PTFI had never compensated the indigenous people as the original stewards of the land where it operates
characterizing Freeport’s concession as a land grab
“The divestment deal cannot be seen as an effort to improve the welfare of the indigenous communities there — to think otherwise is silly,” Maurits said
“People shouldn’t have to depend on funds given by the company,” Maurits added
the company should clean up the mess it left behind so that local people can once again rely on the environment to meet their needs
In August, a coalition of Papuan activists called FMPPF staged a protest calling on PTFI and the Indonesian government to make community rights and welfare a central part of the takeover deal. Their demands included more participation of indigenous people in the mine’s operations
recognition of traditional land rights in the company’s concession area
and more involvement by indigenous communities in drafting the company’s policies
“The company and the national and provincial governments must not forget that the mine isn’t an independent entity,” Maurits said
“There were communities that lived safely there before the company arrived.”

The Grasberg Mine is a vast open pit mine in Papua, Indonesia
For years it has been one of the most productive mines in the world
with massive reserves of gold and copper. Situated high in the rugged Sudirman Mountains near two rare equatorial mountain glaciers
This massive mine sits at the collision point of two tectonic plates
where millions of years ago hot magma intruded into sedimentary rock layers during the uplift of the local mountains
resulting in the formation of copper- and gold-bearing ore. Since the early 1990s
the Grasberg operation has been busily extracting this ore at a staggering volume
the vast mine produced more than 1 billion pounds of copper and 1 million ounces of gold
it is crushed in the mine's milling and concentrating complex
The grinding units at the mill can process a daily average of 265,000 tons of ore
The ore is then sent in a slurry along three pipelines to the seaport of Amamapare
and silver can be shipped to smelters around the world
But while production has temporarily fallen away
the huge reserves of gold and copper remain—albeit deeper underground
Grasberg is now transitioning to underground block carving
with underground mines replacing the work in the pit
such a massive mining project has not gone without its share of controversy
To start are the environmental concerns: Each year
the mine dumps tens of millions of tons of waste into the local river system
which is now almost devoid of fish and generally considered unsuitable for aquatic life
has long insisted that its practices meet industry standards
is not a position held by environmental groups and local citizens
Tensions have also flared at Grasberg due to the low share of revenue going to local Papuans
and questionable payments made by the mine to the Indonesian security forces that protect it.

Grasberg mine tailings are discharged into the lowland Ajkwa River deposition area (ADA) leading to forest inundation and degradation of water bodies critical to indigenous peoples
The extent of the changes and temporal linkages with mining activities are difficult to establish given restricted access to the region and persistent cloud cover
we introduce remote sensing methods to “peer through” atmospheric contamination using a dense Landsat time series to simultaneously quantify forest loss and increases in estuarial suspended particulate matter (SPM) concentration
We identified 138 km2 of forest loss between 1987 and 2014
an area >42 times larger than the mine itself
the rate of disturbance was highly correlated (Pearson’s r = 0.96) with mining activity
Following mine expansion and levee construction along the ADA in the mid-1990s
we recorded significantly (p < 0.05) higher SPM in the Ajkwa Estuary compared to neighboring estuaries
This research provides a means to quantify multiple modes of ecological damage from mine waste disposal or other disturbance events

Also shown are 21, trident-shaped sampling transects at river outlets on either side of the ADA outlet (shown here: 6 km transects for visual clarity). Each trident contains three transects, each with 200 sample points. Map created in Matlab 2015 (www.mathworks.com) using Landsat surface reflectance imagery available from the U.S
Yearly median SPM concentrations as sampled at 201 transect points (within 2 km-long transects) at the Ajkwa Estuary (the outlet for the ADA) and 4,020 points at 20 other nearby river outlets; shaded regions indicate the variability (interquartile range) of SPM for a given year
This variability results from spatial variation over 201 or 4,020 sample points as well as the 1 to 9 image dates used to calculate the annual
The relative increase in SPM at the ADA outlet remained significantly higher (two-sample t-test p < 0.05) than non-ADA outlets for transects up to 2 km in length from the coastline after which transport
or dilution in open waters equilibrated ADA outlet SPM concentrations with those of nearby river system outlets
This comparison of SPM at ADA and non-ADA outlets also allowed us to control for the influence of temporally or spatially variable precipitation patterns

Given that spatial averaging was not applied in this map, the highest values may include cloud edges or silt. Map created in Matlab 2015 (www.mathworks.com) using Landsat surface reflectance imagery available from the U.S
we believe this to be a rare occurrence because red reflectance values of >17% are essentially disallowed by the SPM model (i.e.
(2015) found that a red-band reflectance model for total suspended solids was tractable for reflectance values up to 22%
The most common trajectory observed in this study was the three-segment pixel history representing a single inundation event with no vegetation recovery (Fig. 3a)
the mean error (n = 3500 simulated pixels for disturbance dates between 1990 and 2006) in number of segments was 0.75
error in the date-before-disturbance breakpoint was 124 days
date-before disturbance was underestimated and date-of-nadir was overestimated
there was a consistent tradeoff between parameterizations that yielded high accuracy with respect to number of segments compared to those that yielded more precise fits (e.g.
lower RMSE and lower error in disturbance dating)
we measured 50.2 km2 and 131 km2 of disturbed vegetation within the ADA
both of which are less than the approximately 65 km2 and 164 km2 of disturbance measured by Paull et al

different definitions of “disturbance” in the Upper Ajkwa Estuary: Paull et al
labeled all pixels within the Upper Estuary as “disturbed” while we more specifically identify disturbance only when a given pixel’s NDVI declines below the 0.40 NDVI threshold
We used a single dataset (199 Landsat surface reflectance images) to document coupled riparian vegetative disturbance and coastal water quality degradation
and to examine relationships between these changes and Grasberg tailings deposition
The cloud-resilient disturbance detection approach developed for this study characterizes the pattern of disturbance and degradation in a manner that is unprecedented
with respect to its fine spatial and temporal resolution
this study builds on and contributes to decades of research and advocacy by Papuan environmentalists by illuminating the broad-scale and long-term processes of copper and gold extraction at Grasberg that mutually affect regional ecosystems and indigenous communities
alongside increasing global demand for cheap copper that gave rise to the regulatory environment in which mining operations and waste disposal take priority over regional deforestation and associated human impacts
Grasberg milled over 1.3 billion tons of ore
among the top global producers in terms of throughput
the upwardly biased interquartile range shows that while the “typical daily” (i.e.
median) SPM content may be in the range of 50 g/m3
there are numerous dates where this value is much higher
we hope that our results provide a measure of accountability regarding extant environmental degradation in Papua and
support marginalized indigenous Papuan communities that seek industrial transparency
Our analysis is set within the Mimika Regency of the Papua province of Indonesia (Fig. 1)
This region includes forested and mangrove areas along the Ajkwa River as well as coastal waters of the Arafura Sea approximately 60 km south of Grasberg
Our study’s first component introduces the Noise Insensitive Trajectory Algorithm (NITA) to examine short- and long-term vegetation disturbance along the river; the second component addresses the spatial diffusion of suspended sediments into Arafura coastal waters
All relevant geographic features fit within a single Landsat tile (WRS-2
most of the aforementioned algorithms rely on consistent data availability due to relatively low cloud cover
we sought a disturbance detection algorithm that has ease of implementation
the ability to overcome limitations imposed by missing image dates and remnant atmospheric contamination
and which did not require information on sub-annual phenology
Lacking an exhaustive comparison between NITA and existing disturbance detection algorithms
we do not make the assertion that other algorithms could not perform equally well
The NITA algorithm is implemented on each image pixel and uses all image dates containing valid pixel-level spectral information. The inputs into the algorithm are the set of valid image dates (“x”), the accompanying set of spectral index values (“y”), and the user-defined parameters, max_segment, bail_thresh, prctile, filt_dist, and penalty each described in Table 1
An overview of the NITA algorithm as implemented on a single pixel time series follows (also see Fig. 8):
Calculate the noise variable for the entire times series using the median forward finite difference of the set of spectral values
This variable internalizes atmospheric contamination
linear fit in accordance with the prctile parameter
Compare the value of bail_thresh with the ratio of error of the initial linear fit to noise
where logL is the log-likelihood function value
In order to select the most effective input parameter set
we tested the sensitivity of results against simulated data representing the key pixel trajectories in our Papua study area
Idealized trajectories were manually delineated for disturbances in 1991
and 2003 as well as braided river dynamics
noise was added in two ways: (1) Real sets of valid dates (i.e.
cloud- and SLC error-free dates) were generated from 100 pixels randomly sampled throughout the image
20 valid date sets were randomly selected from the 100 pixel sample
20 sets of random noise were added according to a non-parametric noise model which
was based on the spectral index distributions of 100 forested pixels
This effectively created 400 example pixels for each of the manually-delineated trajectories in question
and penalty were varied to determine their impact on estimates of model complexity (number of segments)
fit RMSE compared to the originating trajectory
date-before-disturbance breakpoint and date-of-nadir breakpoint
changes in filt_dist and penalty would simultaneously improve accuracy of model complexity while reducing accuracy of disturbance dating and vice versa
The parameters max_segment and prctile were not tested because their sensitivities can be understood logically; they are provided to the user for fine tuning
Following selection of a reasonable parameter set (prctile = 90
we conducted an accuracy assessment using 100 manually-generated trajectories based on real data from 100 pixels with 1 to 5 “true” segments
In the same manner as the parameter testing above
these 100 idealized trajectories were used to simulate missing dates and noise
We simulated 10 sets of missing dates and 10 sets of random noise for each trajectory yielding 3900 “pixels” with one segment
These trajectories represented the spectrum of disturbance dates and types present in our study area
Noise standard deviation was set to 0.2 NDVI units
90th percentile SPM values at the ADA outlet were compared to 90th percentile values at non-ADA outlets for pre-1998 and post-1998 periods
This comparison supports identifying changes unique to the ADA outlet transect by decoupling spatial and temporal variability in SPM from changes in river channel morphology
and variability in rainfall or other mesoscale phenomena that may affect SPM transport

Separatist rebels killed a New Zealand national working at a giant gold and copper mine operated by U.S.-based Freeport-McMoran in Indonesia’s Papua province and wounded two Indonesian employees during an attack on Monday
The attack was the latest violence to hit the Tembagapura area near the Grasberg mine
Since late February clashes between armed Papuan separatists and government security forces have left a police officer
“Members of the armed criminal group fired at three PT Freeport Indonesia employees,” Papua police spokesman Ahmad Musthofa Kamal told BenarNews
“One victim died and two others were wounded,” he said
Kamal identified the slain New Zealander as Graeme Thomas Wall
and the other two injured employees as Jibril M.A
Jibril suffered gunshot wounds to his abdomen and right thigh
and Ucok was hit in the right elbow and back
The shooting occurred in the company’s office and housing area in Kuala Kencana
PT Freeport Indonesia spokesman Riza Pratama said
“We are very saddened by the loss of a colleague who died in the shooting incident in the PT Freeport Indonesia office area
He said all staff had been transferred to a safe area nearby
“Our top priority is ensuring the safety of all employees and their families,” Riza via a text message
The West Papua National Liberation Army (TPNPB) operations commander
said his group was responsible for the shooting
“It is better for Freeport to close down and stop all mining activities in the Timika region
We will continue to fight our way,” Hendrik said in a statement
said the shootings were carried out by a separatist faction led by Joni Botak
“At the moment a joint team (of soldiers and police) are in pursuit of the group,” the state-run Antara news agency quoted him as saying
the United Liberation Movement of West Papua (ULMWP)
issued a statement about the attack on the employees at the Grasberg mine
“The TPNPB has allegedly claimed responsibility
The ULMWP urges the international media to treat claims about the shooting with extreme caution,” Benny Wenda
“There is a long history of the Indonesian military carrying out killings
in order to justify further militarization
the ULMWP has always advocated a peaceful approach to the political conflict
and we will not allow the Indonesian State to use this incident as another excuse to delegitimize and criminalize us.”
A low-level separatist conflict has simmered since the 1960s in Papua and West Papua
a region located on Papua Island at the far eastern end of the Indonesian archipelago
The region declared its independence from Dutch colonial rule on Dec
But that was rejected by the Netherlands and later by Indonesia
Indonesian forces invaded the region and annexed it
the region held a referendum in which security forces selected slightly more than 1,000 people to agree to Papua’s formal absorption into the nation
Papua was rocked by weeks of violence in August and September last year after news about allegations that security forces on Java Island had mistreated Papuan students ignited mass protests

Gold mining has been a cornerstone of global economies for centuries
fueling industries and driving financial markets
Countries with vast gold reserves often rely on mining to boost their economies
creating job opportunities and generating wealth
An article published by Express UK reported that while many mines worldwide yield only modest amounts of gold annually
a select few stand out for their extraordinary output
the Grasberg mine in Indonesia holds the crown as the largest and richest gold mine globally
Nestled in the remote mountain ranges of Papua
the Grasberg mine has earned its reputation as a monumental mining operation
With an impressive output of around 48 tonnes of gold each year
it’s the largest gold-producing mine on the planet
its significance does not end there—Grasberg is also one of the largest copper mines in the world
The ore extracted from its depths contains high-grade deposits of both gold and copper
To keep pace with the massive scale of operations
Grasberg employs around 20,000 people and is equipped with its own infrastructure
This extensive network supports the mine’s demanding production schedules and ensures that workers have the necessary resources to carry out their tasks in such a challenging environment
Grasberg is operated by PT Freeport Indonesia
a joint venture between the Indonesian government and the American mining giant Freeport-McMoRan
near the highest peak in Papua—Puncak Jaya—provides access to some of the world’s richest mineral deposits
Grasberg was known for its vast open-pit operations
with three primary underground mines now driving the operation’s continued success
The history of Grasberg dates back to 1936
when Dutch geologist Jean Jacques Dozy first discovered the region’s mineral-rich rocks
large-scale mining operations only commenced in the 1960s
when Freeport-McMoRan secured the rights to develop the site
the mine has undergone continuous expansion
with billions invested in tunnelling systems
Grasberg produced an astonishing 52.9 tonnes of gold (1.7 million ounces)
making it one of the world’s most profitable mining operations
With gold reserves still worth an estimated $40 billion
Grasberg’s future as a major global producer seems secure for decades to come
Environmental concerns have been raised about the impact of sediment and heavy metals on local rivers
political tensions in the region have led to security issues and occasional attacks by separatist groups
Worker strikes and disputes over pay and working conditions have also posed challenges to the operation
the Indonesian government has extended Freeport-McMoRan’s mining lease until 2041
underscoring the significant role Grasberg continues to play in the nation’s economy
As the world’s largest gold and copper mine
Grasberg remains a remarkable example of both the opportunities and challenges that come with such a colossal industrial operation

Freeport-McMoRan Inc has cut its first-quarter copper sales forecast after heavy rains and landslides shuttered operations at its flagship Grasberg mine in Indonesia over the weekend
with the mine not expected to be back online until the end of the month
The temporary shutdown is the latest in a string of extreme weather-related disruptions to rock the mining industry amid the changing global climate
Freeport said late Sunday it had to free 14 employees trapped in an office building because of “significant rainfall and landslides” at Grasberg
the world’s largest gold mine and second-largest copper mine
Mudflow damaged Grasberg’s concentrate processing plant as well as part of the road leading to the mine
Freeport now expects its first-quarter sales to be lower than the previous outlook provided in January for 900 million pounds of copper and 300,000 ounces of gold
The mine typically produces nearly 5 million pounds of copper and 5,000 ounces of gold daily
which is located on the island of Papua’s Sudirman mountain range
is majority controlled by the Indonesian government but Freeport is the mine’s operator
Freeport likely will miss at least four weeks of production at Grasberg because of the floods
who cut his first-quarter earnings estimate for the company by 9% to 40 cents per share
“This does not materially impact the Freeport investment case
but it does highlight that there are many operating risks in mining
and even the best operators are not immune,” LaFemina said in a note to clients
Shares of Phoenix-based Freeport fell about 0.3% to $42.22 in Monday afternoon trading in New York

Rio Tinto and Freeport McMoRan have reached agreements to divest a majority stake in the Grasberg copper and gold mine to Indonesian state mining company PT Indonesia Asahan Aluminium (Persero) (Inalum) for a total consideration of $3.85bn
The agreements are in line with the Indonesian Government’s policy
to ensure domestic mining companies hold a majority stake in foreign miners operating in the country
Rio Tinto currently holds a 40% participating interest in the Grasberg mine
with a 40% share in production above a pre-agreed level and 40% of all production after 2022
Inalum will have 51.2% ownership in PT Freeport Indonesia
which is Freeport McMoRan’s operating subsidiary in the country
while Freeport will retain a 48.8% interest
while the remaining $350m will be paid to Freeport
In August this year, Freeport signed a deal with the government to hand over a majority stake in the Grasberg mine
The deal also includes the government granting a special mining permit to Freeport to continue ore extraction until 2041 once Inalum gains 51% interest
Don’t let policy changes catch you off guard
Stay proactive with real-time data and expert analysis
Rio Tinto chief executive J-S Jacques said: “This agreement is a significant step towards the sale of our interest in Grasberg and provides further evidence of our commitment to strengthening the portfolio by selling non-core assets and driving higher returns across the business
maintain a strong balance sheet and allocate capital to the highest value opportunities in order to ensure that Rio Tinto continues to deliver sector leading returns to shareholders”
Subject to regulatory approvals and other conditions
the completion of the transactions is slated for the first half of next year
Grasberg is regarded as the world’s second largest copper reserves and produced 468kt of copper last year
Copper miner Freeport Indonesia has temporarily halted mining and processing work at its Grasberg mine after flooding and debris flow from heavy rains and landslides damaged its milling complex
Freeport-McMoRan Inc said on Sunday evening
Freeport-McMoRan said it expected first-quarter 2023 sales to be lower than the previous outlook provided in January for 900 million pounds of copper and 300,000 ounces of gold
Freeport Indonesia’s daily output was nearly 5 million pounds of copper and 5,000 ounces of gold
Preliminary estimates indicate operations can be restored by the end of February
adding that there was no impact to PT Freeport Indonesia’s long-term plans
The company said it had freed 14 employees trapped in an office building because of the flood
but added there were no casualties in the recovery effort launched on Saturday
“Some of the concentrate processing plant had mudflow and several sections of the mine road were damaged,” Freeport Indonesia Chief Executive Tony Wenas said in a statement on Sunday
adding that the situation was under control

The world’s largest gold mines come in all shapes and sizes
Here’s a look at the true behemoths and which companies own them
the world’s 10 largest gold mines produced nearly 337 metric tons (MT) of the yellow metal in 2022
Nevada Gold Mines is the largest gold-mining complex in the world, producing 68.5 percent more of the precious metal than the next largest gold mine on this list. The operation is a joint venture between Barrick and Newmont (TSX:NGT,NYSE:NEM)
the world's largest gold-producing company
which has a 38.5 percent stake in the asset
Nevada Gold Mines encompasses several prolific gold deposits
The gold-mining complex has combined proven and probable reserves of 29.6 million ounces
and measured and indicated resources of 49 million ounces
it's located in the top US gold-mining jurisdiction
The US ranks as the world's fourth largest gold-producing country
In keeping with its Greenhouse Gas Reduction Roadmap, Barrick is building a 200 megawatt alternating current photovoltaic solar facility to accelerate its decarbonization program
The Grasberg mining district is located in Indonesia and is the second largest gold mine and second largest copper mine in the world. The majority of the asset is owned by Freeport-McMoRan (NYSE:FCX)
the ninth largest gold-mining company by production
Grasberg consists of the Grasberg block cave, the Deep Mill Level Zone (DMLZ) and Big Gossan. Daily production at Grasberg reportedly amounts to approximately 5 million pounds of copper and 5,000 ounces of gold
Freeport-McMoRan's subsidiary PT Freeport Indonesia is undertaking long-term mine development activities at the Kucing Liar deposit in the Grasberg mining district
which the company says has the potential to produce over 6 billion pounds of copper and 6 million ounces of gold between 2028 and the end of 2041
Olimpiada is an open-pit operation that has been in production since 1996. It is located in Russia, which tied with Australia as the second largest gold-producing country in 2022. The mine is owned by the fifth largest gold-mining company by production, Polyus Gold (LSE:PLZL,MCX:PLZL)
The Boddington gold and copper mine is one of the largest gold-producing mines in Australia
The mine has been in operation since 2009 and is wholly owned by Newmont
Looking forward, strong production at Boddington is expected to have a significant impact on the stability of Newmont's total gold output for 2023
the company reports that "(b)ased on mine sequencing
gold production is expected to decline in 2024 and 2025 due to lower grade ore and stripping in the South pit."
The mine commenced production in 2013 and is operated by Barrick
Kibali holds proven and probable gold reserves of 4.6 million ounces and measured and indicated gold resources of 7.1 million ounces. In March 2023, Barrick reported that "(f)or the fourth successive year
exploration more than replaced the gold that Kibali mined in 2022
extending the mine’s Tier One production profile to 2033."
Pueblo Viejo is located in the Dominican Republic
where it is responsible for nearly 50 percent of the country's gold production
the gold mine is run by Pueblo Viejo Dominicana

JAKARTA — The Indonesian government expects to take a controlling stake in the operator of the world’s biggest copper and gold mine this month
even as sanctions it imposed for environmental violations threaten to hamstring the multibillion-dollar deal
Arizona-based Freeport-McMoRan is expected to divest its decades-old majority stake in its Indonesian subsidiary
the operator of the Grasberg mine in Papua province
In testimony to the country’s parliament on May 30, Ignasius said the move, mandated under the country’s mining law
would cut Freeport’s stake in PTFI to 49 percent
although it will remain the mine’s operator
through state-owned mining holding company PT Inalum
The takeover has been valued as high as $8.1 billion
Discussions between Freeport and PT Inalum have “reached the final stage,” Jonan said as reported by local media
“We hope the whole acquisition process can be completed in June
which is among the government’s requests to extend [Freeport’s operation].”
Inalum CEO Budi Gunadi Sadikin told reporters in May that the main hurdle to the acquisition was the dumping of mining waste
for which the government has imposed sanctions on the miner
Budi said Freeport had “made breaches that need to be revised through the environmental audit,” Reuters reported on May 24
“The biggest issue is the issue of tailings — that has to be improved,” Sadikin said
The sanctions on PTFI, imposed in October last year, stemmed from findings by the Indonesian state auditor
that identified a wide range of irregularities in the company’s operations and contract
These included indications of reckless mining
An earlier review by the agency pegged the environmental damage from the company’s operations at 185 trillion rupiah ($13.1 billion)
the Ministry of Environment and Forestry followed up with a pair of decrees ordering PTFI to overhaul its waste management within six months
They include slashing toxicity levels at dumping sites and producing a strategic environmental impact assessment
Freeport has balked at the conditions laid out
saying they imposed “undue and unachievable restrictions” on Freeport’s basic operations
Reuters also quoted local media as reporting that Adkerson
“I am deeply concerned that these actions have the potential to derail the progress that all of us have worked so hard to achieve.”
“The main point is that [Freeport] must fix all of this
though we know it can’t all be done at one time,” Siti Nurbaya Bakar
“We are giving them a transition period in which they can consult with the government [on the waste management].”
The minister and officials from Freeport have met several times to discuss the decrees on the tailings management
with the latest taking place in Jakarta on May 17
Siti said that particular meeting lasted almost three hours
She said her office would continue to talk with Freeport officials
was not as optimistic about the company being able to comply with the decrees
“The new ministerial decrees are impossible to be implemented right now, and we are still trying to negotiate with the environment ministry to find a solution,” he said on May 24 as reported by local media
The BPK audit that set off the sanctions and decrees over PTFI’s waste management practices also found that Freeport had used 4,536 hectares (11,208 acres) of protected forest area without obtaining the proper permits
The National Commission on Human Rights (Komnas HAM), a state-funded body, said in March 2017 that PTFI had never compensated the indigenous people as the original stewards of the land where it operates
despite neither side seeing eye to eye on the key issues
Thousands of workers at the world’s largest copper and gold mine
run by U.S.-based Freeport McMoRan in the Indonesian province of Papua
have been instructed to remain on the company’s premises or risk being furloughed without pay
amid an outbreak at the mine that has seen 56 employees test positive for COVID-19
Freeport announced the test results last week, telling reporters that the outbreak had been detected in mid-March after an employee tested positive for the disease
prompting the firm to test 400 workers living in the same barracks
and then sent into quarantine,” an underground worker at the mine told Mongabay by phone
has emerged as one of the worst coronavirus clusters on the Indonesian part of the giant island of New Guinea
Three hundred and five people in Papua and neighboring West Papua province have tested positive for the disease, with seven deaths, according to the national COVID-19 task force
The two provinces have taken aggressive measures to stop the virus, imposing travel restrictions on most air and sea travel. The region is one of the remotest in Indonesia, with scant public health facilities and isolated indigenous communities who could be particularly vulnerable to the disease
Indonesia as a whole has seen 930 coronavirus deaths
Some countries, such as Peru, Mexico, Mozambique and Malaysia, have suspended or reduced production at mines to prevent the spread of the virus
In April, Freeport closed a mine in New Mexico after three workers tested positive for COVID-19. It has also announced plans to cut its 2020 costs by 18% as copper prices plummet
Despite calls to halt operations at its mine in Papua
Freeport said operations would continue following redoubled health protocols
such as requiring a body temperature check for every employee who wants to enter the company’s work area
Richard Adkerson, the CEO of Freeport McMoRan, said last month that testing and screening activities at the Grasberg mine “are much more advanced than much of what we’re seeing today in communities in the United States.”
Those who want to leave the company’s premises in the Papuan highlands must sign a form
saying they understand they may not be able to return to work and may not be compensated during their absence
Riza said employees were “free to choose” whether to stay or go
but did not address the part about them not being paid
“We are facing a dilemma,” the underground worker said
“If we take a break and return to the city
we have to sign a statement that means we are voluntarily resigning.”
Around a million Indonesian workers have been furloughed due the pandemic, with hundreds of thousands more laid off, President Joko Widodo said on April 30

Aser called on operations at the mine to be suspended
with workers receiving pay during the closure as Indonesia grapples with the coronavirus outbreak
“The safety of workers is in jeopardy because we are forced to work in the midst of COVID-19,” he said in a statement
So we have to be willing to work amid the coronavirus.”
said Grasberg workers were facing a situation akin to “slavery.”
noting that the 2009 Mining Act stipulates that mining business activities can be halted in the event of an epidemic
said the province might shut down the mine if the situation worsened
“We have asked [Freeoport] to conduct a rapid test for all workers
we are going to review the trend,” he said by phone
“If by that time there’s a spike in the case
we are open to the option to halt the operation.”

The order is in effect for an indefinite period
Workers are barred from returning home at the end of May for Idul Fitri

“It’s impossible we can take any social distance,” he said
“Every morning we jostle to get into the bus to work
just like the other normal days before the virus spread,” he said
“We feel uncomfortable and confused,” he added
