PT Vale Indonesia Tbk. (INCO) is exploring cooperation in the development of the new Tanamalia mine in the Sorowako Block, South Sulawesi, by partnering with a European automaker.Vale Indonesia Director and Chief Sustainability and Corporate Affairs Officer Budiawansyah said the project is planned to be integrated with a high pressure acid leach (HPAL)-based hydrometallurgical smelter, which requires limonite nickel ore.“This is the future and it is now being initiated. This is cooperation in the Tanamalia Block. It is very special because one of our partners is a leading vehicle manufacturer from Europe,” Budiawansyah said at the Hipmi Grand Seminar on Thursday (Aug. 6, 2026).According to the presentation materials shown, the development of the mine is currently at the second stage of the front end loading (FEL) study, covering the preparation of the feasibility study (FS), economic feasibility, development and technical aspects, operations, legal matters, as well as environmental, social, and governance (ESG) aspects.Meanwhile, the HPAL smelter project will be built together with a partner and is currently at the partner selection stage.Furthermore, the Tanamalia Block is part of Vale Indonesia’s special mining business permit (IUPK), which covers the Loeha, Lemo-Lemo, and Lingkona IUPK sub-blocks, with a total area of 13,556 hectares (ha).The Tanamalia Block is also located within the Sorowako forest area, with a further exploration permit covering 17,239 ha. The Tanamalia area encompasses Loeha village and a small part of Rante Angin village in East Luwu.It was explained that if the nickel content is sufficiently adequate, construction will begin in 2027—2028, with mining commencing as early as 2031.Vale’s Nickel ReservesFor information, Vale Indonesia Head of Studies and Exploration Tyas Agustinus Rabudianto said the company’s nickel reserves as of Dec. 31, 2025, stood at 1.18 billion wet tonnes, or around 664 million dry tonnes. The reserves can be mined for up to 20 years.Vale also has nickel resources of around 1.67 billion wet tonnes, equivalent to 1 billion dry tonnes. Therefore, the company’s reserves can still be increased to support around 50 years of mining.Tyas said the unmined nickel reserves consist of 695.57 million wet tonnes of limonite (low-grade nickel) and 489.40 million wet tonnes of saprolite (high-grade nickel).For resources, limonite ore is estimated at 657.1 million wet tonnes, while saprolite stands at 1.02 billion wet tonnes.“At least 20 years. For our reserves, we still have resources that we have not used. One and a half times what we have now. If combined, it could total around 50 years,” Tyas said during a public discussion in South Jakarta on Wednesday (April 29, 2026).Tyas said the company allocates around 2% of its revenue, or about USD 15—USD 16 million per year, for exploration costs, so the company’s nickel ore resources and reserves are expected to continue increasing.The exploration budget can also be increased if needed in the future. Tyas claimed that the board of directors had already instructed this.Currently, of Vale Indonesia’s total concession area of 118,017 ha, only around 68% has been explored.VW Eyes Vale ProjectMeanwhile, German automaker Volkswagen AG (VW) was previously reported to have expressed interest in working with Vale Indonesia on the development of an electric vehicle battery ecosystem.Associate Energy Analyst at the Ministry of Energy and Mineral Resources (ESDM) Secretariat General Fitria Astuti Firman said the government is preparing national ESG standards through a gap analysis between domestic regulations and international standards to accommodate foreign investors in the critical minerals sector.In this regard, she said VW is interested in entering Vale’s nickel project subject to strict ESG requirements.“This step is crucial so that Indonesian mineral products can be absorbed into global supply chains. A successful example of this implementation is PT Vale’s cooperation with global automotive giants such as Ford and Volkswagen, which require compliance with global ESG standards,” she said at an Indef public discussion on Wednesday (June 17, 2026).Previously, VW, through its battery division PowerCO, was indeed reported to have been interested in partnering with Vale, Ford Motor Co., and Zhejiang Huayou Cobalt Co.Bahlil Lahadalia, when he was still Minister of Investment/Head of the Investment Coordinating Board (BKPM), also confirmed the reports. He said VW was interested in building an electric vehicle battery industry.“VW will cooperate with several national and foreign companies. We are ready to oversee the investment plan so that it can be realized soon,” Bahlil said in a press release on Tuesday (April 18, 2023).PowerCo SE is a Volkswagen subsidiary established in 2022 and headquartered in Salzgitter, Germany.PowerCo handles all of Volkswagen Group’s battery activities, from processing raw materials and developing batteries to managing its European gigafactories.For information, based on INCO data as of April 2026, the Indonesia Growth Project (IGP) Pomalaa has attracted attention due to its largest investment value, reaching US$4.5 billion, through collaboration with Ford and Huayou.To date, construction progress on the HPAL plant at the site has reached 65%, while development of the mining sector has reached 72%.The project is claimed to employ more than 5,000 workers and is targeted to begin production in August 2026 with a capacity of 120,000 tonnes of mixed hydroxide precipitate (MHP) per year.On Feb. 28, 2026, Vale sold the first nickel ore from the mine at the project. The company is targeting production of 300,000 tonnes of limonite per month, or around 9,677 tonnes per day.Meanwhile, the IGP Morowali smelter project has entered the operational stage. The Bahodopi Block, covering 22,699 ha, reportedly began operations in the first quarter of 2025.For the mining sector, Phase 1 construction has reached 100%, and the company is now focusing on preparations to complete Phase 2, which is targeted for completion in 2027. Vale said that by early 2026, 2.2 million tonnes of ore had been sold from the project.Meanwhile, construction progress on the HPAL plant, developed in partnership with GEM and EcoPro and having a capacity of 66,000 tonnes of MHP per year, has reached 27% and is targeted to begin operations this year. Total investment in the project amounts to USD 2 billion.In South Sulawesi, Vale and Huayou are developing the IGP Sorowako Limonite project in the 70,566-ha Sorowako Block to support the downstream processing of limonite nickel.As of April 2026, construction of the mine had reached 42%, while progress on the HPAL plant stood at 18%.The facility is designed to have an annual production capacity of 60,000 tonnes of MHP and is targeted to be fully operational in 2027.

Bumi Resources Targets Full Loyal Metals Acquisition by Mid-August
Bumi Resources Targets Full Loyal Metals Acquisition by Mid-August
06 Aug 2026, 05:01 PM 1403

PT Bumi Resources Tbk (BUMI) is targeting the completion of its planned acquisition of Australian mining company Loyal Metals Ltd by mid-August 2026, although the deal remains in its preliminary stage pending regulatory and shareholder approvals.The company said it has signed a Scheme Implementation Deed (SID) with Loyal Metals as the initial agreement to begin the acquisition process. However, the transaction has not yet become legally effective, as several conditions precedent still need to be fulfilled under Australian law.BUMI Director RA Sri Dharmayanti said the acquisition remains subject to approval from Loyal Metals' shareholders, court approval in Australia, and the completion of all applicable legal requirements. She emphasized that no transfer of funds or shares has taken place."There has been no final binding transaction regarding the transfer of Loyal Metals' share ownership to the company," Sri wrote in a disclosure to the Indonesia Stock Exchange on Tuesday, August 4, 2026.BUMI plans to acquire 100% of Loyal Metals' outstanding shares, under a court-approved scheme by Australia’s Corporation Act 2001. Loyal shareholders are expected to receive A$0.45 per share, valuing the company at approximately A$79.11 million. The offer represents a 40.6% premium over Loyal Metals' closing share price on April 24, 2026, and is also significantly above its recent five-day and 10-day volume-weighted average prices.Loyal Metals' management said the transaction offers shareholders full cash consideration at an attractive premium while reducing development risks associated with the company's gold and copper mining projects in Australia and Canada.Earnings Strengthen as Diversification ContinuesBUMI also reported stronger financial and operational performance in the first half of 2026, supporting its strategy to diversify beyond coal through overseas mineral assets.Revenue rose 27.9% year-on-year to USD 866.8 million (approximately IDR 14.30 trillion) from USD 677.9 million (around IDR 11.19 trillion) a year earlier. Operating profit increased 50.3% to USD 83.1 million (around IDR 1.37 trillion), while net profit attributable to shareholders surged 188.4% to USD 58.9 million (approximately IDR 972 billion).Coal production climbed 7.1% to 38.5 million tons, while sales increased 11.7% to 38.8 million tons, reflecting resilient demand that reduced coal inventories to 1.7 million tons from 2.7 million tons a year earlier.The company's average free-on-board (FOB) selling price improved to USD 62.9 per ton (around Rp1.04 million) from USD 61.3 per ton (around  IDR 1.01 million). BUMI attributed its stronger margins to higher production and sales volumes, firmer selling prices, and improved mining efficiency, while maintaining its full-year production cost target of USD 42–44 per ton (approximately IDR 693,000–IDR 726,000).The company said it will continue pursuing its diversification strategy, including integrating newly acquired mining assets in Australia once the Loyal Metals transaction is completed.

Freeport Prepares New Mine to Stabilize Production
Freeport Prepares New Mine to Stabilize Production
05 Aug 2026, 04:25 PM 721

PT Freeport Indonesia (PTIF) is preparing to develop a new underground mine to ensure long-term production stability beyond the expiration of its Special Mining Business License (IUPK) in 2041. The company said the project requires a long development timeline, making early planning and regulatory certainty essential.Tony Wenas, PTFI President said underground mine development typically takes between 15 and 20 years from exploration to commercial production.As a result, Freeport has applied for an extension of its IUPK well before the current license expires; the company said the extension would allow it to invest in discovering and developing new mineral reserves before production from existing mines begins to decline after 2041."We will develop a new mine that may take around 15 years. But we need certainty from now. That is why we are applying for the extension now," said Tony, as cited by CNN Indonesia TV, on Monday, August 3, 2026.He said early extension is intended to prevent production drop after 2041 by ensuring new underground operations are ready before existing reserves are depleted."So that when 2041 comes, there will be no depletion in production. Production will remain stable because we are confident enough to invest in finding new reserves that we believe exist," he adds.Long-term Benefits for Jobs and State RevenueAccording to Tony, maintaining mining operations preserves employment for around 35,000 workers allowing the company's community development programs, valued at nearly Rp2 trillion (approximately US$113 million) annually.He adds continued operations would also sustain Freeport's contribution to state revenue. The company generated around Rp75 trillion (approximately US$4.2 billion) in benefits for the government last year, with annual contributions reaching Rp120 trillion (around US$6.8 billion) by 2028 if operations continue."The benefits for the country reached Rp75 trillion last year, and by 2028 they are estimated to reach Rp120 trillion per year. That would also stop if there is no continuity," Tony said.He stressed the mining license extension would benefit all stakeholders, arguing that underground mines cannot simply be transferred to another operator once production ends because the mined-out underground structure would no longer be suitable for future extraction."No one benefits if operations stop in 2041. Others also cannot simply continue mining because the mine will have already collapsed. There are benefits for everyone if the license is extended," Tony concluded.

02 Aug 2026, 09:03 AM 846

PT ABM Investama Tbk (ABMM) accelerated production from its coal mining operations in Aceh during the first half of 2026 to capitalize on improving coal market conditions. The strategy became one of the main drivers of the company's higher profitability amid ongoing challenges in the mining industry.Hans Manoe, Director of PT ABM Investama Tbk, said the company recorded improved profitability during the period, supported by higher coal production and the stabilization of its mining contractor business."Although the industry continues to face various challenges, supportive coal prices have provided the company with an opportunity to capitalize on the momentum through operational excellence," Hans said in a statement, as quoted on Sunday (Aug. 2, 2026).The company said higher coal prices, driven by elevated fuel costs amid global geopolitical tensions, created momentum to increase production, particularly in the second quarter of 2026. The move contributed to higher coal sales volumes while supporting the company's net profit.During the first half of 2026, ABMM posted relatively stable consolidated revenue of USD 506.2 million. However, adjusted EBITDA rose 6.4% year on year to USD 346.9 million, while net profit jumped 41.9% to US$39.9 million.The company also increased coal production by 14.2% to 17.9 million tons, driven by higher output at one of its mining sites in South Kalimantan. Meanwhile, higher coal sales were also supported by the production ramp-up at its Aceh mine during the second quarter of 2026.In addition to taking advantage of favorable coal prices, ABMM maintained disciplined cost management, enabling it to preserve profitability. The stability of its mining services contractor business also contributed through improvements in various operational indicators.In the logistics segment, one of the company's subsidiaries secured a long-term logistics services contract from a key customer, classified as an A-list client, strengthening the sustainability of its business going forward.Entering the second half of 2026, ABMM expects production from its Aceh mine to continue increasing. At the same time, the company is completing the permitting process for a new coal mining asset in Central Kalimantan, which is targeted for completion by the end of this year.

PT Vale Indonesia Tbk (INCO) reported higher nickel matte production in the second quarter of 2026. Improved operational performance following the completion of the Electric Furnace 3 rebuild project was the main driver behind the production increase, strengthening the company's growth foundation amid the dynamics of the global nickel industry.According to its earnings report released on Thursday (July 30, 2026), PT Vale produced 16,153 metric tons of nickel matte during the April-June 2026 period. The figure was up about 19% from production of 13,620 tons in the first quarter of 2026. Cumulative production in the first half of 2026 reached 29,773 tons.The increase in production was supported by the completion of the Electric Furnace 3 rebuild project in June 2026. The company said the project was completed while maintaining workplace safety standards and operational reliability, leaving it optimistic about achieving its production target for the full year.In addition to higher nickel matte production, PT Vale also recorded significant growth in its nickel ore sales business through its two strategic projects in Bahodopi and Pomalaa. At the Bahodopi Block, saprolite nickel ore sales volume reached 1.07 million wet metric tons (wmt) in the second quarter of 2026, up from 886,094 wmt in the previous quarter. Total sales in the first half therefore reached 1.96 million wmt.Meanwhile, the Pomalaa Block posted an even sharper increase. Nickel ore sales rose to 495,601 wmt in the second quarter of 2026 from just 88,983 wmt in the first quarter. Cumulative sales volume in the first half reached 584,584 wmt, far higher than 147,491 wmt in the same period last year.The company said the higher volumes from Bahodopi and Pomalaa demonstrated the success of its expansion strategy through the development of three mining hubs in Sorowako, Bahodopi, and Pomalaa. The strategy not only increases production capacity but also broadens the company's revenue sources beyond its core Sorowako operations.Stronger operational performance also had a positive impact on financial results. PT Vale posted revenue of USD 290 million in the second quarter of 2026, up about 15% from USD 253 million in the previous quarter. The increase was driven by higher production and a rise in the average realized nickel matte price to USD 14,765 per ton.In terms of profitability, EBITDA rose 45% quarter on quarter to USD 116 million from US$80 million in the first quarter. Net profit increased 39% to USD 61 million, compared with USD 44 million in the previous period.PT Vale Indonesia President Director and Chief Executive Officer Bernardus Irmanto said the results reflected the company's success in strengthening its operational foundation while preparing for long-term growth."The arrival of the autoclave marks a significant step forward in developing Indonesia's integrated battery raw materials value chain and reinforces PT Vale's commitment to supporting the national downstream processing agenda," Bernardus said.He added that PT Vale will continue accelerating the development of its High Pressure Acid Leach (HPAL) project to process limonite ore into Mixed Hydroxide Precipitate (MHP), a key raw material for the electric vehicle battery industry. At the same time, the company continued investing in strategic projects, with capital expenditure of around USD 116 million during the second quarter of 2026 to strengthen production capacity and support sustainable growth.

Dairi Prima Mineral Ready to Develop Underground Mine
Dairi Prima Mineral Ready to Develop Underground Mine
27 Jul 2026, 09:01 AM 908

PT Dairi Prima Mineral (DPM) is preparing to develop an underground mine to produce zinc (Zn) and lead (Pb). The joint venture between PT Bumi Resources Minerals Tbk (BRMS) and NFC (Hong Kong) Metal Resources Company Limited will develop the Anjing Hitam and Lae Jehe mining prospects in Dairi Regency, North Sumatra.Dairi Prima Mineral Technical Manager Widianto said the company this year secured final approval for its feasibility study as well as an environmental permit through an addendum to its Environmental Impact Assessment (Amdal). DPM has also obtained a Forest Area Borrow-to-Use Permit (PPKH) covering 53.11 hectares for mining activities, valid through Dec. 29, 2047.DPM will first develop the Anjing Hitam prospect, which, based on its 2025 estimate, contains mineral resources of 8.53 million tons grading 13.8% zinc and 7.9% lead. Following resource conversion, Anjing Hitam has ore reserves of 7.70 million tons with grades of 12.5% zinc and 7.3% lead.DPM estimates that developing the Anjing Hitam underground mine and constructing its ore processing plant will require investment of around USD 450 million. The company plans to begin underground mining development and plant construction in the first quarter of 2027.DPM expects the construction process to take around two years. "God willing, we expect to begin extracting ore from the underground mine in the fourth quarter of 2028. Ore processing is then expected to start in the first quarter of 2029," Widianto said during the Modern Underground Mining Discussion held on Monday (July 27, 2026).DPM's processing plant is designed to handle 1 million dry tons of ore annually. The ore will contain zinc grades of around 11%-15% and lead grades of between 6%-9%, producing lead concentrate with a grade of 56% and zinc concentrate with a grade of 52%.Over the life of the operation, DPM estimates it will produce 2.43 million dry tons of concentrate containing 821,150 tons of zinc and 473,895 tons of lead. In addition to zinc and lead concentrates, ore processing will also produce sulfur concentrate."The commodities we plan to produce, namely lead and zinc, are classified as critical and strategic minerals. We hope to realize the DPM project," Widianto said.Zinc and lead are used by various domestic industries, including welding, batteries, and automotive batteries. Sulfur concentrate production also carries strategic value by reducing Indonesia's reliance on imports. Demand for sulfur is expected to rise as more High Pressure Acid Leach (HPAL) facilities begin operating in the country.Based on current reserve estimates, the Anjing Hitam prospect has a mine life of around nine years. DPM is continuing efforts to increase resources and reserves to extend the mine's operating life. At the same time, the company is preparing to develop the Lae Jehe prospect.According to its 2025 estimate, Lae Jehe contains mineral resources of 27.90 million tons grading 6.1% zinc and 3.7% lead. Ore reserves are estimated at 10 million tons with grades of 6.4% zinc and 3.8% lead."We are still developing the Lae Jehe prospect because its grades remain lower than those at Anjing Hitam, so we are continuing infill drilling. Our goal is to have Lae Jehe ready before Anjing Hitam is depleted, allowing operations to continue seamlessly," Widianto said.NFC (Hong Kong) Metal Resources Company Limited is the majority shareholder in DPM with a 51% stake, while BRMS holds the remaining 49%.Permitting and Environmental AspectsDPM has undergone a lengthy process before reaching the stage of mine development. The project's permitting process has spanned nearly three decades since its Contract of Work was signed in 1998. Exploration activities were conducted between 1997 and 2002, leading to the discovery of the zinc and lead deposit later named the Anjing Hitam prospect.The first feasibility study was completed in 2004, while the Environmental Impact Assessment (Amdal) was approved by the Dairi Regent in 2005. DPM subsequently obtained a Forest Area Borrow-to-Use Permit (IPPKH) covering 53.11 hectares in 2012 before revising its feasibility study in 2015 following changes to the location of the mine portal, the Tailings Storage Facility (TSF), and the explosives storage facility.In 2022, the government approved an addendum to the Environmental Impact Assessment accommodating the three changes. However, in 2024, Indonesia's Supreme Court ruled in favor of a community group's lawsuit challenging the approval of the Amdal addendum, prompting the Environment Minister to revoke the approval in 2025 in accordance with the court's ruling.Based on the latest assessment underpinning the revised feasibility study, DPM has two main prospects: Anjing Hitam and Lae Jehe. Widianto emphasized that the company will meet environmental and sustainability requirements in operating the underground zinc and lead mine.He explained that DPM will apply a combination of longhole stoping and cut-and-fill mining methods, allowing mined-out voids to be backfilled using processed tailings. The use of tailings as backfill material has received technical approval from the government."Tailings will not be disposed of or stored on the surface. Instead, the material will first be separated into liquid and solid components. The liquid will be reused in the processing plant, while the solids will be mixed with cement and pumped back into the underground workings as backfill material," Widianto said.The cut-and-fill mining method minimizes land disturbance, helping preserve forests and surrounding ecosystems. "The tailings backfill system not only maintains the stability of underground mining areas but also supports environmental protection and compliance with regulations," Widianto said.
