Eramet has resumed operations at the Weda Bay nickel mine in Indonesia after halting production in May 2026 due to the exhaustion of its production quota.The French mining company said operations at Weda Bay Nickel (WBN) have gradually resumed after receiving authorization from the Indonesian government.“Mining operations at Weda Bay Nickel (WBN) have gradually resumed with permission from the Indonesian authorities,” Eramet said in a statement, as quoted by MiningWeekly.Eramet has not explained whether WBN has received an additional production quota. A company spokesperson also declined to provide further details regarding the authorization.The company said it would update its 2026 external sales guidance for nickel ore in due course. WBN is also continuing discussions with the Indonesian government regarding mine operations.Previously, Weda Bay, one of the world's largest nickel mines, halted operations and entered a care and maintenance phase in May 2026 after its initial production quota of 12 million wet metric tons (WMT) for the year was exhausted.The quota was significantly lower than the initial 2025 allocation of 32 million WMT.Indonesia, the world's largest nickel producer, cut mining permit volumes this year as part of efforts to tighten controls over commodity production, exports and prices.Uncertainty over mining permits in Indonesia has also weighed on Eramet's financial performance. The company is now preparing a capital increase and the sale of several stakes in a number of business lines.Eramet owns WBN together with Chinese steel group Tsingshan and PT Aneka Tambang Tbk (ANTM).

PT Vale Indonesia Tbk. (INCO)'s High-Pressure Acid Leach (HPAL) smelter project in Pomalaa, Southeast Sulawesi, is expected to begin full operations in 2027. The smelter will have a production capacity of up to 120,000 tons of mixed hydroxide precipitate (MHP).Vale Indonesia Director Muhammad Asril said that on September 15, 2026, Vale would begin trials of the smelter. All end-to-end processes at the Pomalaa HPAL facility will subsequently be tested.Vale had initially targeted mechanical completion of the HPAL project for December 2026. However, progress to date has allowed the company to bring forward the project's completion schedule.“We can bring it forward by around 2–3 months, allowing us to achieve mechanical completion in September or October, so we can ramp up over approximately 3–6 months. In 2027, we can begin full ramp-up and reach full production of 120,000 tons of MHP at Pomalaa,” he said at the Public Expose Live 2026 on Thursday (September 10, 2026).For context, IGP Pomalaa is a mining and HPAL processing plant project with an investment value of US$4.5 billion. In developing the project, Vale has partnered with Chinese EV battery producer Zhejiang Huayou Cobalt Co., Ltd. and US automaker Ford Motor Co.The IGP Pomalaa project comprises a nickel ore mining project and a High-Pressure Acid Leach (HPAL) processing project. The project's estimated annual output will reach 120,000 tons of nickel and around 15,000 tons of cobalt contained in MHP products.“On the mining side, we have actually already started mining. The mining service company is already onsite. We are currently producing saprolite and limonite for HPAL requirements,” he said.Vale said development of the IGP Pomalaa mine had reached 83%, while progress on the HPAL facility had reached 86%. Nevertheless, mineral ore sales have already begun, with the first ore sale carried out on February 28, 2026.Vale has set a target of producing 300,000 tons of limonite per month, or around 9,677 tons per day.Previously, Vale had targeted total nickel matte production of 67,645 metric tons throughout 2026. Management set the target with optimism following the completion of the Furnace III rebuild project and an improvement in the nickel grade of the ore mined by the company.Vale Indonesia Deputy President Director Abu Ashar said the company's production in the first half of 2026 had been relatively stable. The nickel grade from mining operations was also considered the highest in the past three years.“The repair work has been completed, the nickel grade from mining to the plant is quite good, and plant operations have also been relatively stable, so we are optimistic about achieving our annual production target of 67,645 tons this year,” he said at the Public Expose Live 2026 on Thursday (September 10, 2026).

PT Timah Targets 30,000-Ton Increase in Reserves in 2026
PT Timah Targets 30,000-Ton Increase in Reserves in 2026
10 Sep 2026, 08:45 AM 486

PT Timah (Persero) Tbk is targeting an additional 30,000 tons of tin reserves in 2026 to replace depletion, or the reduction in reserves resulting from production activities, while maintaining the sustainability of the company's operations.PT Timah Corporate Strategy and Business Development Director Harry Budi Sidharta said increasing resources and reserves was one of the company's focuses in its strategy to boost operations and production.“With a target of adding 30,000 tons in reserves, at least that would replace or correspond to the results of depletion. This is to maintain the sustainability of the company's production,” Harry said during the online Public Expose Live 2026 in Jakarta on Thursday.As of the first half of 2026, PT Timah recorded 798,000 tons of tin mineral resources and 312,000 tons of tin mineral reserves, both measured in Sn.To strengthen these resources and reserves, the company is carrying out exploration activities both on land and at sea.According to the company's presentation, activities carried out in 2026 included geological surveys covering 3,216 hectares, geophysical surveys spanning 76 kilometers, and topographical surveys covering 17,638 hectares.The company also recorded 41,104 meters of exploration drilling and 12,971 meters of infill drilling as part of its strategy to increase resources and reserves.PT Timah Production and Commercial Director Ilhamsyah Mahendra said exploration was a priority in 2026 as it represents the initial stage in discovering new resources and reserves.“For the mining business, it starts with exploration activities, which are currently a priority in 2026. This is then followed by the actual mining process for tin minerals,” Ilhamsyah said.In addition to exploration, the company has begun focusing on processing primary tin and optimizing production through the addition of equipment, improvements in equipment productivity, and the acceleration of new mine-site development.Since July and August 2026, PT Timah has added four production suction dredgers to support its operational targets through the end of the year. Additional equipment has also been deployed in several onshore mining areas.“We hope to maximize the addition of equipment and increase the productivity of our mining equipment through the end of the year,” Ilhamsyah said.Separately from its reserve-addition target, the company's 2026 Work Plan and Budget (RKAP) sets a target of producing 30,000 tons of tin ore, measured in Sn.In the first half of 2026, the company's tin ore production reached 12,232 tons of Sn, up 75% from the same period a year earlier. Tin metal production reached 10,865 metric tons, representing annual growth of 58%.Ilhamsyah said the company remains on track to meet its operational and production targets for this year after making a number of improvements to its operational fundamentals and processing and refining infrastructure.For 2027, he said the company's operational and production targets would be more or less the same as those for 2026. However, the focus will remain on increasing resources and reserves to maintain the sustainability of its operations and business.In addition to primary tin, the company is also developing the potential of rare earth metals from tin-associated minerals, including monazite. The development remains at the technology assessment stage in collaboration with several partners.

MIND ID Eyes Greater Control of Copper Supply Chain as Electrification Grows
MIND ID Eyes Greater Control of Copper Supply Chain as Electrification Grows
09 Sep 2026, 08:55 AM 364

MIND ID is pushing to strengthen the copper supply chain to bolster mineral sovereignty while creating added value domestically.MIND ID Institutional Relations Division Head Selly Adriatika said the move had become increasingly strategic amid rising demand for copper to support various industrial sectors, ranging from electricity, transmission networks and electronics to electric vehicles and renewable energy.She said the integration of assets and capabilities among companies within the holding was part of a strategy to build a mutually supportive mineral value chain.“MIND ID does not view each asset and company as a standalone entity. We integrate the resources and capabilities of Holding Members so they can support one another, allowing processed mineral products to be further developed as part of the national industrial supply chain and generate added value domestically,” Selly said in an official statement, as quoted on Wednesday (Sept. 9, 2026).According to her, control over copper resources is becoming increasingly important amid accelerating electrification and the global energy transition. In this context, MIND ID's majority ownership of PT Freeport Indonesia (PTFI) serves as a strategic instrument to strengthen national control over copper resources.Selly said efforts to strengthen the value chain were not limited to copper mining and refining. PTFI is also developing a Precious Metal Refinery (PMR) in Gresik, East Java, which processes anode slime, a byproduct of copper concentrate processing, into precious metals.PTFI's PMR has an annual production capacity of around 50 tons of gold and 200 tons of silver. Selly said the facility could extend Indonesia's mineral value chain while opening opportunities to utilize processed products to meet domestic market demand.According to her, the integration began to materialize in February 2025, when PTFI delivered 125 kilograms of 99.99%-purity gold bars produced by the PMR to PT Aneka Tambang Tbk. (ANTAM), worth around Rp207 billion.PTFI and ANTAM had previously also agreed on the purchase of up to 30 tons of gold per year.Domestic demand is one of the opportunities that could be strengthened through the integration. World Gold Council data showed demand for gold bars and coins in Indonesia reached 31.6 tons in 2025. Meanwhile, gold consumption for jewelry reached 16.6 tons.Thus, total demand across the two segments reached around 48.2 tons, close to PTFI's PMR gold production capacity of around 50 tons per year.Selly said strengthening the mineral value chain would become increasingly important as demand for strategic minerals rises. Therefore, PTFI's development is aimed not only at increasing production but also at strengthening connectivity between mining, processing, refining and downstream industries domestically.In the copper sector, accelerating the recovery of Grasberg production and optimizing the PTFI Gresik Smelter are key parts of the strategy.Selly said the two facilities would not only determine Indonesia's national copper production capacity but could also increase the utilization of associated minerals and derivative products for further processing domestically.“What MIND ID is doing today is part of the journey toward building a sovereign mining industry, where the natural wealth we possess can be managed and developed to the fullest for the benefit of the nation. Indonesia's resources must become a source of strength for today's generation as well as a foundation for generations to come,” she said.Selly added that through control of strategic assets, downstreaming and integration among Holding Members, MIND ID aims to ensure that Indonesian minerals do not remain mere commodities but can develop into part of the national industrial supply chain.

TMS Targets October Start for Sangihe Gold Mine Production
TMS Targets October Start for Sangihe Gold Mine Production
08 Sep 2026, 03:47 PM 757

PT Tambang Mas Sangihe (TMS) is targeting the reissuance of approval for gold mining production operations on Sangihe Island, North Sulawesi, in October 2026.TMS President Director Terry Filbert said the company is currently still awaiting the reissuance of the production operations approval, which was previously granted in 2021 but was later temporarily revoked on administrative grounds in 2023.“We hope that in the near future, hopefully next month, we will receive it,” Filbert said during a discussion with journalists on Thursday, September 3, 2026.According to Filbert, the company has fulfilled all requirements requested by the government. The application for the reissuance of the production operations approval was submitted on October 25, 2025, and the company is currently waiting for the Ministry of Energy and Mineral Resources (ESDM) to complete the process.TMS, he said, has completed a feasibility study, an environmental impact assessment (AMDAL), a project development plan, and a post-mining plan, and has also prepared a reclamation guarantee.The company also said it is still conducting community engagement around the proposed mining area.“We actually have not completed the community engagement. We are still in the process of engaging with the community — this is an ongoing process,” he said.Only 65 HectaresFilbert said TMS has a relatively large contract area of around 42,000 hectares. However, only around 65 hectares will be used for mining activities because the area has been approved under the AMDAL.Filbert stressed that holding a large concession area does not mean the entire area will be used for mining activities.“Just because we have 42,000 hectares does not mean we will use 42,000 hectares,” he said.He said mining activities will only be carried out in designated areas that have previously been planned and explored.Illegal Mining ActivitiesFilbert also stressed that TMS has never conducted mining or gold processing activities at the site.Instead, he suspected that illegal mining activities had been taking place while the company’s licensing process was delayed since 2023.“We have never conducted any mining activities at all. We have never carried out a single process here,” he said.According to Filbert, the illegal mining activities even involved heavy equipment. He said there were as many as around 50 units of heavy equipment at the site.Filbert also claimed that the activities had caused environmental damage and accidents.He said at least six people had died in illegal mining activities that he was aware of and that had been publicly reported. He also suspected that mangrove areas and protected forests had been damaged, and that mercury contamination had occurred in water and soil.Company Promises Priority for Local WorkersIf the production operations approval is reissued, TMS said its mining activities will provide economic benefits for the people of Sangihe.The company will prioritize qualified local workers who meet the required qualifications.“If you are from Sangihe, you will have the first opportunity for the job if you meet the qualifications,” he said.In addition to creating direct and indirect employment, TMS plans to provide technical training and employment benefits in accordance with Indonesian labor regulations.Filbert also said the company will provide wages and various employment benefits, including health insurance and social security.He hopes the company’s activities can drive growth in non-mining sectors, including services, trade, tourism, and transportation.TMS Plans to Support TourismTMS also said it plans to support tourism development in Sangihe, particularly diving tourism.Filbert said Sangihe has marine tourism potential, including coral reefs, manta rays, and a number of diving sites.The company is even considering supporting and subsidizing improved air connectivity to Sangihe to encourage tourist arrivals.“Not everyone can be a miner. Not everyone wants to be a miner,” he said.According to him, developing non-mining sectors is important so that the economic benefits generated by the company do not depend solely on employment in the mining sector.Company Promises Reclamation and Environmental MonitoringRegarding environmental protection, Filbert said TMS has prepared a reclamation guarantee of around USD 500,000.The company will also continuously monitor water quality and biodiversity, he said.Waste and tailings management have been planned from the outset. Reclamation will also be carried out gradually throughout the mining activities.“As we conduct mining, we will carry out reclamation. Then eventually, we will close and restore the entire area,” he said.Filbert said the company will preserve the topsoil during mining activities so that it can be reused in the reclamation process.Former mining areas will later be replanted with vegetation so that they are expected to resemble conditions before mining activities began.Geothermal Power Plant Under ConsiderationIn addition to mining activities, TMS said it plans to conduct an initial study on the development of a geothermal power plant on Sangihe Island.Filbert said the proposed power plant could have a capacity of 8 to 10 megawatts.According to him, a more stable electricity supply could help address the island’s current dependence on diesel-powered generators.Filbert believes a stable electricity supply would not only support the company’s operations but could also attract other industries to invest in Sangihe.“At the same time, the electricity could be distributed across the entire island,” he said.TMS also plans to improve internet connectivity, including providing high-speed internet access to schools and village offices through Starlink.The company said it has provided scholarships to university students and plans to continue supporting education and community facilities.TMS Licensing HistoryTMS originated from a Contract of Work granted by the Indonesian government in 1997 to a company called Bre-X. The project was subsequently acquired by a company then known as East Asia Minerals in 2007.Filbert joined the company in 2017 with the task of bringing the project to the production stage.TMS subsequently obtained environmental impact assessment (AMDAL) approval in 2020 and production operations approval in 2021.However, the production operations approval was later temporarily revoked on administrative grounds in 2023. Since then, the company has reapplied to commence production operations.Filbert said the company is currently waiting for the Ministry of Energy and Mineral Resources to complete the process so that the project can enter the production stage.

07 Sep 2026, 03:43 PM 1045

PT Bumi Resources Tbk. (BUMI), through its Australian subsidiary Bumi Resources Australia Pty Ltd (BRA), has acquired 100% of the shares of Loyal Metals Ltd. (LLM), an Australian copper and gold mining company, in a transaction valued at IDR 1 trillion.Bumi Resources Director R.A. Sri Dharmayanti said the transaction was carried out on September 4, 2026, through BRA, a BUMI subsidiary wholly owned by the company.“The company, through its Australian subsidiary Bumi Resources Australia Pty Ltd, which is a subsidiary of the company established under Australian law and 100% owned by the company, has carried out an acquisition transaction for 175,710,515 shares, representing 100% of the issued and fully paid-up shares of Loyal,” BUMI said in an information disclosure on Friday (September 4, 2026).With the transaction, BUMI, through BRA, has become the 100% shareholder of Loyal Metals Ltd., a company established under Australian law.The acquisition transaction was valued at IDR 1,004,742,244,136.50 (IDR 1 trillion), equivalent to AUD 79,069,731.75. As a result, Loyal Metals is now fully indirectly owned by BUMI through BRA.As Indonesia’s largest coal producer, BUMI is stepping up its business diversification strategy.Previously, PT Bumi Etam Chemical (BEC) held the groundbreaking ceremony for the national strategic project (PSN) to gasify coal into methanol on Monday (August 31, 2026).The project is located in the Batuta Chemical Industrial Park (BCIP) area, Bengalon District, East Kutai Regency, East Kalimantan. Construction will utilize approximately 93 hectares of land.The joint venture between two subsidiaries of PT Bumi Resources Tbk (BUMI), namely PT Arutmin Indonesia and PT Kaltim Prima Coal (KPC), targets production of around 2 million tons of methanol per year and has the potential to save up to IDR 7.1 trillion in foreign exchange annually.BEC President Director Rio Supin said the company has entered the engineering stage through the preparation of a Front-End Engineering Design (FEED) and an Engineering, Procurement, Construction, and Commissioning (EPCC) Framework Agreement with PT Istana Karang Laut (IKL) and China National Chemical Engineering Co., Ltd. (CNCEC) since July 29, 2026.“Indonesia’s first coal gasification project is ready to enter the implementation stage, with commissioning targeted for 2029. BEC is ready to support national energy independence and resilience,” Rio said.

Darma Henwa (DEWA) Diversifies Business Portfolio to Drive Sustainable Growth
Darma Henwa (DEWA) Diversifies Business Portfolio to Drive Sustainable Growth
05 Sep 2026, 04:13 PM 622

PT Darma Henwa Tbk (DEWA) is preparing to expand its business portfolio by entering the critical minerals and precious metals sectors beyond coal. The diversification move is aimed at transforming the company into a highly competitive investment holding company with sustainable performance growth.The company has long been widely known as an integrated mining services contractor, handling numerous national coal projects. However, management is now refining a long-term roadmap to develop its own mining concession assets while also targeting higher-value-added mineral commodities."Historically, we have indeed been a mining services contractor, but going forward, Darma Henwa wants to become an investment holding company. Going forward, we will not only rely on coal, but will also begin entering other sectors and developing our own assets, particularly the Gayo Mineral Resources gold and copper mine in Aceh, which is currently in the exploration phase," DEWA Director Ricardo Silaen said in The Fundamentals podcast broadcast on YouTube by IDX Channel, as quoted on Saturday (Sept. 5, 2026).Although it is beginning to position itself as a mine owner, the issuer with the DEWA stock code said its core expertise in mining contracting will remain a pillar of the company's operations. The company has just secured a new project contract while actively exploring opportunities to work on nickel and other mineral mines."We want to build an integrated, diversified business that delivers sustainable growth with a combination of good margins and growth. Going forward, we see opportunities in other minerals such as nickel as a contractor, while also developing Gayo as a mine owner," Ricardo said.To strengthen its business ecosystem and reduce operating costs, the company has established three supporting business units, namely DH Listrik, Arunika in the hospitality sector, and DH Infrastruktur. The establishment of the power business line was prompted by a surge in diesel fuel prices, which have doubled and become the largest cost component for conventional heavy equipment."We have prepared these three new businesses to support future needs, particularly to mitigate the surge in diesel energy prices, which have risen from IDR 13,000 to IDR 26,000 per liter. We are striving not only to diversify in terms of business, but also in the energy sources used because the company's competitiveness going forward depends on that," he said.In mitigating the risk of fuel price fluctuations, the company has implemented a cost adjustment scheme borne by the mine owners, while management focuses on maximizing energy efficiency in the field.Meanwhile, industry players hope the government can maintain a consistent regulatory climate so as not to hinder the expansion of the national mining industry."Our service rates are highly competitive compared with competitors, with a pass-through mechanism for fuel, so price increases are borne by the mine owners while we maintain energy-use efficiency. We also hope that regulations going forward will not flip-flop and will continue to support growth, rather than changing constantly or tending to be exploitative," Ricardo said.

J Resources Asia (PSAB) Posts USD 177.89 Million Profit, Up 803%
J Resources Asia (PSAB) Posts USD 177.89 Million Profit, Up 803%
01 Sep 2026, 03:57 PM 488

PT J Resources Asia Pasifik Tbk (PSAB) posted an 803% surge in profit in the first half of 2026.Based on its financial report published in an information disclosure on Tuesday (September 1, 2026), PSAB recorded net profit of USD 177.89 million in the first half of 2026, soaring 803% year-on-year (yoy) from USD 19.69 million in the same period last year.The biggest factor behind the profit surge was a gain from the disposal of a subsidiary amounting to USD 298.60 million, a line item that did not appear at all in the same period last year. The one-off non-operating gain was the single largest contributor to the increase in the company’s profit before tax.On the top line, the company recorded sales of USD 160.64 million, up around 14.5% yoy from USD 140.30 million in the first half of 2025.Interestingly, cost of sales fell sharply from USD 52.31 million to just USD 18.95 million, sending gross profit up 61% to USD 141.69 million from USD 87.99 million previously.On the other hand, several significant expenses weighed on the company’s results during the period, including amortization and write-offs, which jumped sharply to USD 105.57 million from just USD 7.54 million previously.Impairment losses on fixed assets reached USD 59.58 million, far higher than USD 3.75 million a year earlier. Impairment losses on mining properties stood at USD 25.02 million, compared with none in the previous period.General and administrative expenses rose to USD 46.43 million from USD 29.53 million, while losses from changes in the fair value of investments amounted to USD 6.73 million, reversing a modest gain of USD 6.82 thousand a year earlier.Despite these substantial expenses, their impact remained far smaller than the divestment gain, allowing profit before tax to surge to USD 190.25 million from USD 37.79 million in the previous period.PSAB also reported total assets of USD 636 million as of June 2026, down from USD 821.56 million at the end of December 2025. The company’s liabilities and equity stood at USD 201.35 million and USD 435.5 million, respectively.Meanwhile, the company’s total cash and cash equivalents at the end of the period stood at USD 17.06 million, down from USD 39.44 million previously.

Amman Mineral Leverages AI and Experts to Optimize Copper Production
Amman Mineral Leverages AI and Experts to Optimize Copper Production
01 Sep 2026, 03:55 PM 522

Amman Mineral Internasional is relying on collaboration between artificial intelligence (AI) and the expertise of its professionals to optimize copper production in Indonesia, particularly through the Batu Hijau mining project and the development of a smelter in West Nusa Tenggara, as reported by Investor Daily.The company estimates production will reach 900,000 metric tons of dry concentrate in 2026, containing approximately 220,000 tons of copper and 579,000 ounces of gold. The newly completed copper smelter is capable of processing up to 900,000 metric tons of concentrate annually, supporting the production of high-quality copper cathodes and other supporting products.Amman views copper as a strategic mineral whose demand is rising significantly due to the acceleration of electrification, renewable energy, and artificial intelligence technology. Indonesia has proven copper reserves of 21 million tons and is the world’s fifth-largest copper producer.Amman President Commissioner Agoes Projosasmito explained, “The outlook for the global copper industry remains positive. Key opportunities are being driven by copper’s strategic role in electrification, construction, transportation, renewable energy technologies, and AI-based computing.”BRIN Deputy for Development Policy Nunung Nuryartono said the competitiveness of the mineral industry depends on the integration of technology, governance, and sustainability. “Downstreaming is not merely about building smelters, but about building intelligence and accountability at every stage of the industrial value chain,” he said.Nunung added that AI presents opportunities to improve production efficiency and data-driven decision-making, but this must be balanced with good governance to ensure that the environment and public trust are not compromised.Amman has developed an AI system called Artificial Intelligence Dashboard Automation (AIDA), which helps optimize mineral processing at the plant. The system uses historical and real-time data to provide recommendations for more efficient processes and improve mineral recovery rates.Amman President Director Arief Widyawan Sidarto said, “The company applies AI to optimize recovery rates in the flotation process. AI drives greater efficiency by improving metal output relative to mining and processing costs.” He added that the improvement supports more sustainable resource utilization.AIDA does not replace humans but instead strengthens decision-making through collaboration between AI and operational expertise. “Every four hours, the operations and metallurgy teams jointly review AIDA’s recommendations to determine process adjustments,” Arief said.Amman Vice President of Corporate Communications Kartika Octaviana said, “The success lies in the synergy between data, innovation, and the expertise of our team. When technology and human experience work hand in hand, we are able to make better decisions and create greater value.”Amman has increased mineral recovery by around 2.5% through AI-based optimization, a significant achievement for the Batu Hijau operation, which already has best-in-class recovery rates.Didit, a member of Amman’s metallurgy team, also helped develop the Controlled Potential Sulfidisation (CPS) innovation using an Oxidation Reduction Potential (ORP) sensor to address declining copper recovery from stockpile ore caused by oxidation. The innovation successfully increased copper recovery significantly while reducing chemical consumption by up to 18.3%.The success of the innovation was presented at the MetPlant 2026 metallurgy conference in Adelaide, Australia, which serves as a forum for the exchange of best practices in mineral processing.Didit said, “A positive work culture and support from leadership were key to the development of this innovation. This is proof that local talent from West Sumbawa can produce technical work recognized globally.”
