Sumbawa Timur Mining’s Onto Project Could Rival Freeport Indonesia Grasberg
Sumbawa Timur Mining’s Onto Project Could Rival Freeport Indonesia Grasberg
14 Aug 2026, 04:02 PM 108

Sumbawa Timur Mining’s Onto project in West Nusa Tenggara is still under exploration, with its copper-gold resource estimated at more than 2 billion tons.Indonesia still has significant untapped gold potential across several regions, with one exploration-stage project in West Nusa Tenggara potentially holding a larger gold resource than PT Freeport Indonesia’s Grasberg operation in Central Papua, according to the Indonesian Mining Institute (IMI).Indonesian Mining Institute Chairman Irwandy Arif said the potential highlights the scale of Indonesia’s remaining mineral resources and the need for continued exploration to identify new mining deposits.One of the projects highlighted by Irwandy is the Hu’u Project, operated by PT Sumbawa Timur Mining (STM) in Hu’u District, Dompu Regency, West Nusa Tenggara.“Its potential is still very large. In West Nusa Tenggara, we have Sumbawa Timur Mining. Its reserves could potentially exceed those of Freeport. We have also identified the same mineralization corridor in that area, although it was known before,” Irwandy said at the Mindialogue 2026 event in Jakarta, as quoted Thursday (August 13).STM is currently exploring the Onto copper-gold deposit, which forms part of its Hu’u Project. The project remains in the development stage and has not yet entered commercial production. Vale Base Metals describes Hu’u as a tier-one copper-gold development district, with the Onto deposit discovered in 2013 and currently progressing through a pre-feasibility study.STM’s own data estimates the Onto deposit contains more than 2 billion tons of mineral resources. The company says the project is one of the world’s major copper-gold discoveries and remains open laterally and at depth.STM has held a seventh-generation Contract of Work for the Hu’u area since 1998. Exploration activities began in 2010, while the Onto deposit was discovered in 2013. The company subsequently entered the pre-feasibility study stage in 2019.STM is majority-owned by Vale through Eastern Star Resources, which holds 80%, while state-owned mining company PT Aneka Tambang Tbk (ANTM) owns the remaining 20%.The company has continued to advance the project toward feasibility. Local government officials said in April 2026 that STM had entered the feasibility-study stage as part of preparations for eventual production.The scale of the Onto resource has attracted attention because the deposit contains both copper and gold. A 2021 resource estimate cited by Petromindo put the total mineral resource at around 2.1 billion tons, comprising 1.1 billion tons of indicated resources and 1 billion tons of inferred resources.The project is therefore not yet comparable to an operating mine in terms of proven production or commercially recoverable reserves. Its potential will depend on the completion of further exploration, feasibility studies, permitting and eventual mine development.Freeport Indonesia, meanwhile, operates the Grasberg mining complex in Central Papua, one of the world’s largest copper and gold mining operations.The comparison made by IMI therefore refers specifically to the potential scale of STM’s gold resources relative to Freeport Indonesia’s operations in Papua, rather than to Freeport’s global parent company.The Hu’u Project is currently being advanced as a future copper-gold mining operation, with STM continuing technical studies and exploration before any final investment and construction decisions are made.

Vale’s Pomalaa HPAL Nickel Smelter Project Completed, Commissioning Set to Begin
Vale’s Pomalaa HPAL Nickel Smelter Project Completed, Commissioning Set to Begin

PT Vale Indonesia Tbk. (INCO) announced that construction of the nickel smelter infrastructure at the Pomalaa Block has been completed. The company is now awaiting initial testing before proceeding to the commissioning stage.Vale Director and Chief Sustainability and Corporate Affairs Officer Budiawansyah explained that the high-pressure acid leach (HPAL)-based hydrometallurgical smelter in Pomalaa has entered the mechanical completion stage, with construction reaching 100%.Budiawansyah said the inauguration and commissioning of the HPAL smelter at the Pomalaa Block are still awaiting the final testing stage.“In the context of mechanical completion, it has been completed, it’s already 100%. Mechanical completion means the construction process has been mechanically completed; what remains is testing and commissioning,” Budiawansyah said at a media briefing in South Jakarta on Thursday (August 13, 2026).“It won’t take long [for the testing]. As for the celebration, it’s just a matter of when we want to hold it. What matters is that the physical facility is ready to operate,” he stressed.Budi explained that the Pomalaa smelter has a production capacity of around 120,000 tons of nickel content in mixed hydroxide precipitate (MHP), requiring 21 million tons of limonite ore per year and 720,000 tons of saprolite per year.He said the Pomalaa smelter is expected to absorb around 10,679 workers during the construction stage and 3,017 workers during operations.The total investment is estimated at USD 3.4 billion, with Vale partnering with Huayou and Ford in the construction of the smelter.Meanwhile, the mine at the Pomalaa Block has been operating since the first quarter of 2026, with annual production of around 7 million tons of saprolite ore and 21 million tons of limonite ore. Currently, production from the Pomalaa mine has reached 2 million tons of saprolite and 2.1 million tons of limonite.Previously, Budi indicated that the company was targeting the domestic electric vehicle (EV) battery market, as the HPAL smelter in Pomalaa is set to begin operations in the third quarter of 2026.Budi said the company is currently focused on completing the project’s construction, including exploring potential product uptake with business partners.However, he said the project could become an important part of establishing a domestic EV battery industry ecosystem.Moreover, the intermediate product produced, MHP, is an initial raw material in the EV battery supply chain.“Regarding the offtaker, we are focused on delivering the project because, basically, we are discussing with our partners and also where we will take this downstreaming process. Because, fundamentally, the government wants to see the formation of an industrial ecosystem [for EV batteries] domestically,” Budiawansyah told the media in mid-March.“Because we see that the MHP-based EV supply chain is still quite long from MHP to battery packing. So, in any case, we are coordinating with the government on how to continue realizing an integrated battery ecosystem in Indonesia,” he stressed.On February 28, 2026, Vale sold the first nickel ore from the mine at the project. The company is targeting production of 300,000 tons of limonite per month, or around 9,677 tons per day.On the other hand, the IGP Morowali smelter project has entered the operational progress stage. The Bahodopi Block, covering 22,699 hectares, reportedly began operations in the first quarter of 2025.For the mining sector, Phase 1 construction has reached 100%, and the company is now focused on preparing for the completion of Phase 2, which is targeted for 2027. Vale said that in early 2026, 2.2 million tons of ore had been sold from the project.Meanwhile, construction of the HPAL plant developed in partnership with GEM and EcoPro, with a capacity of 66,000 tons of MHP per year, has reached 36% and is targeted for completion in March 2027. The project’s total investment amounts to USD 2 billion.In South Sulawesi, Vale and Huayou are developing the IGP Sorowako Limonite project at the 70,566-hectare Sorowako Block to support the downstream processing of limonite nickel.As of June 2026, mine construction had reached 50%, while progress on the HPAL plant stood at 19%.The facility is designed to have a production capacity of 60,000 tons of MHP per year and is targeted for completion in December 2027.

UNTR to Build Smelter After Acquiring PSAB Gold Mine, Completion Set for 2029
UNTR to Build Smelter After Acquiring PSAB Gold Mine, Completion Set for 2029
12 Aug 2026, 04:07 PM 110

PT United Tractors Tbk (UNTR) is preparing to build a smelter following the acquisition of the Doup Gold Project mine from PT J Resources Asia Pasifik Tbk (PSAB).In early 2026, UNTR, through its subsidiary PT Danusa Tambang Nusantara (DTN), completed the acquisition of the gold mine in Kotabunan District, East Bolaang Mongondow Regency, North Sulawesi. The transaction was carried out through the purchase of shares in PT Arafura Surya Alam (ASA) for USD 540 million, or around IDR 8.85 trillion.United Tractors Human Capital & Sustainability Director Ari Sutrisno said the company is currently preparing for exploration and development at the Doup Block, including the construction of a smelter. He hopes construction of the smelter can be completed within around three years.“This includes preparations for the construction of the smelter. The completion target is 2029,” Ari told Katadata.co.id in Jakarta, as quoted on Wednesday (August 12).The Doup Block in North Sulawesi has proven and probable ore reserves, in accordance with JORC standards, of 1.57 million ounces of gold. Meanwhile, measured, indicated, and inferred mineral resources amount to 3.11 million ounces of gold.On the other hand, looking at the performance of UNTR’s gold segment, the gold and other minerals mining segment posted revenue of IDR 2.4 trillion in the first half of 2026, down 66% from the same period last year. The decline was mainly caused by an 82% drop in gold sales.Meanwhile, the gold mining businesses operated through Agincourt Resources and Sumbawa Juta Raya recorded total gold sales equivalent to 23,000 ounces through the first half of 2026. The figure was down from 125,000 ounces in the same period last year.As of the first half of 2026, UNTR recorded net revenue of IDR 58.3 trillion, down 15% year on year from Rp68.5 trillion in the same period last year. Management said the decline was mainly driven by lower gold sales from PT Agincourt Resources.The performance of the heavy equipment and thermal and metallurgical coal mining segments also weakened due to the lower allocation under the 2026 National Coal Work Plan and Budget (RKAB).Net profit excluding non-recurring items fell 48% to IDR 4.3 trillion. The decline was mainly caused by lower gold sales from the Martabe Gold Mine, whose operations had been temporarily halted.Management also said the decline in revenue was due to the lower 2026 coal RKAB allocation. The company said operations at the Martabe Gold Mine resumed in the second quarter of 2026.

PT Petrosea Tbk (PTRO) has secured two new coal mining services contracts with an estimated total value of around IDR 9.3 trillion. The contracts come from PT Pesona Bara Cakrawala (PBC) and PT Cakrawala Bara Persada (CBP), which are indirect subsidiaries of PT Singaraja Putra Tbk (SINI).The mining services agreements between PTRO, PBC, and CBP were signed on Thursday, July 23, 2026. Both contracts have terms extending for the life of the mines.Under the new contracts, PTRO will serve as the mining services contractor for two coal projects located in Kapuas Regency, Central Kalimantan.PTRO Corporate Secretary Anto Broto explained that the scope of PTRO’s work under the contracts includes several key mining activities.“The Company will act as a mining services contractor, with the scope of work including overburden removal, rock material excavation, and coal mining,” Anto Broto said in an official statement on Thursday, July 23, 2026.The total estimated value of the PTRO contracts refers to the Indonesian Coal Index (ICI) as of July 23, 2026.PTRO Secures IDR 7.7 Trillion Contract from PBC ProjectOne of the contracts secured by PTRO comes from the PBC mining project. The company holds a Mining Business License for Production Operation (IUP-OP) in Kapuas Regency, Central Kalimantan.For the PBC project, PTRO will handle mining activities with an estimated overburden production volume of 189 million bank cubic meters (BCM).Meanwhile, estimated coal production from the project reaches 42 million tons. The value of the mining services contract secured by PTRO from PBC is estimated at IDR 7.7 trillion.From the PBC mining project, SINI projects total revenue of up to USD 2.6 billion, or around IDR 45.6 trillion, over the contract period. The coal produced from the project has a GAR calorific value of 4,200.PTRO’s Contract from CBP Reaches IDR 1.6 TrillionIn addition to PBC, PTRO has also secured a mining services contract from CBP. The company also holds an IUP-OP in Kapuas Regency, Central Kalimantan.The CBP project has an estimated overburden production volume of 40 million BCM. Meanwhile, coal production is estimated at 8 million tons over the life of the mine.For the project, the value of the mining services contract awarded to PTRO reaches around IDR 1.6 trillion.SINI projects that the CBP mining project can generate total revenue of up to USD 656 million, or around IDR 11.5 trillion, over the contract period. Coal from the CBP project has a GAR calorific value of 5,000.Based on a disclosure to the Indonesia Stock Exchange on Tuesday, July 21, 2026, SINI projects that the PBC project will begin commercial operations in the fourth quarter of 2026. Meanwhile, the CBP project is targeted to begin commercial operations in the fourth quarter of 2027.PTRO and SINI Have an Affiliated RelationshipThe mining services contracts between PTRO and PBC and CBP also involve an affiliated relationship. PBC and CBP are indirect subsidiaries of SINI through PT Dwi Daya Swakarya.Each company holds a 60% ownership stake through PT Dwi Daya Swakarya. Under this structure, PBC and CBP are affiliated with PTRO through common shareholders.SINI President Director Amir Antolis explained that one of SINI’s controllers, Hapsoro, is also an indirect major shareholder of PTRO.“One of SINI’s controllers (Mr. Hapsoro) is also an indirect Major Shareholder of PTRO,” Amir said in an official statement.As of the end of June 2026, Hapsoro directly held a 9% stake in SINI. In addition, Hapsoro also held an indirect stake in PTRO through PT Sentosa Bersama Mitra (SBM) of 2.55%.PTRO Becomes SINI Rights Issue Standby BuyerThe business relationship between PTRO and SINI has also grown closer through a corporate action currently being undertaken by SINI. PTRO has been appointed as the standby buyer in SINI’s IDR 3.61 trillion rights issue.Through the corporate action, PTRO is projected to acquire around 21.76% to 24.67% of SINI’s issued and paid-up capital after the rights issue is completed.In addition to serving as standby buyer, PTRO will also sell its subsidiary, PT Kemilau Mulia Sakti (KMS), to SINI in a transaction valued at IDR 1.73 trillion after the rights issue is completed.KMS has a mine life extending to 2038. SINI projects that coal production from KMS’s concession will be gradually increased from 1 million tons to 5 million tons per year.SINI management targets KMS revenue of USD 52 million in 2026, rising to USD 158.97 million in 2027. KMS’ revenue contribution is projected at 21.40% and 27.06%, respectively, of the company’s total revenue.

Tin Production Rises 75%, TINS Profit Surges 805% in H1 2026
Tin Production Rises 75%, TINS Profit Surges 805% in H1 2026
12 Aug 2026, 03:37 PM 109

PT Timah Tbk (TINS) posted a significant improvement in performance in the first half of 2026, in line with higher tin production and sales. Tighter oversight of mining activities and efforts to crack down on illegal mining in Bangka Belitung were also cited as supporting the company’s operational improvement.TINS recorded net profit attributable to owners of the parent entity of IDR 2.71 trillion in the first half of 2026. The figure surged 805% from IDR 300.07 billion in the same period last year.The company’s revenue also grew 146.9% to IDR 10.42 trillion. Meanwhile, operating profit increased from IDR 380.20 billion to IDR 3.46 trillion.The increase pushed TINS’ operating profit margin from 9.01% to 33.24%.From an operational standpoint, tin ore production increased 75% to 12,232 tons of Sn. Tin metal production grew 58% to 10,865 metric tons, while sales volume rose 85% to 10,984 metric tons.The performance was also supported by a 52% increase in the average tin selling price to USD 49,794 per metric ton.In addition to pricing factors, TINS’ operational improvement was also said to have been supported by tighter oversight and security of Mining Business Permit Areas (WIUP), as well as support from the Central Government Task Force.The improved performance came amid the government’s efforts to crack down on illegal mining activities and tin smuggling routes in Bangka Belitung.The enforcement operations, involving law enforcement authorities, began in September 2025. The efforts were aimed at strengthening oversight of mining activities and securing national tin reserves.BRI Danareksa analyst Andhika Audrey said the crackdown had gradually brought tin mining activities back into the formal ecosystem.The condition provided room for TINS to secure ore supplies from its concession areas while increasing the utilization of its production facilities.“The impact is beginning to be seen in the increase in production, sales volume, and improvement in TINS’ margins. If oversight of mines and smuggling routes is carried out consistently, the company’s performance growth has the potential to be more sustainable,” Andhika said.TINS Shares StrengthenThe improvement in TINS’ performance was also accompanied by a rise in the company’s share price.TINS shares increased by around 17.7%, from IDR 3,270 on June 30, 2026, to IDR 3,850 on August 10, 2026.At that price, TINS’ market capitalization reached around IDR 28.67 trillion. Meanwhile, based on first-half 2026 earnings simply annualized, TINS shares were trading at around 5.3 times indicative PER.According to Andhika, the closure of illegal mines could become one of the catalysts for a re-rating of TINS shares.“The market is no longer viewing the company merely as a beneficiary of higher tin prices, but also as a company with opportunities for more measurable growth in production, cash flow, and profit,” Andhika said.

DEWA Reveals GMR IPO Plans and Exploration Progress at Aceh Gold and Copper Mine
DEWA Reveals GMR IPO Plans and Exploration Progress at Aceh Gold and Copper Mine
11 Aug 2026, 03:59 PM 103

PT Darma Henwa Tbk (DEWA) is continuing its expansion in gold and copper mining. Through its subsidiary, PT Gayo Mineral Resources (GMR), DEWA is carrying out field work for the second phase of exploration at a gold and copper mine located in Gayo Lues, Aceh.Darma Henwa Director Ricardo Silaen said GMR’s gold and copper mine exploration is divided into three stages. The project is currently carrying out field work for the second stage, while the third stage is expected to be completed in 2027.However, Ricardo has yet to disclose details on the investment value or the production schedule and targets for the project.“To be more optimal and comprehensive, the investment value and production targets can be disclosed once the third phase of exploration and all studies are completed, so that the Company can maximize the existing potential,” Ricardo told Kontan.co.id on Sunday (August 9, 2026).GMR has a concession covering 34,500 hectares. One of several deposit areas identified based on the first phase of exploration is located in Tengkereng Atas.Based on a valuation conducted by a Public Appraisal Services Office (KJJP), the gold and copper mining project has a gross asset value of around IDR 7 trillion.In terms of valuation, the figure will still depend on the results of exploration and additional resources and reserves that can subsequently be confirmed. Infrastructure development, mine development, and a processing plant will be carried out in subsequent stages after the third phase of exploration is completed and the required investment has been determined.“GMR is still in the exploration stage and is a greenfield project. At present, the Company cannot provide an estimate of the capex requirement until GMR begins production because the exploration process and feasibility study are still underway. Regarding the production target, the Company will provide information to the public in due course,” Ricardo said.Previously, information circulated that DEWA would explore opportunities to raise funds in the capital market through an initial public offering (IPO) of GMR shares. The corporate action is one of the funding options to develop the gold and copper mine being developed by GMR.Responding to the news, Ricardo stressed that DEWA is still considering various funding alternatives for GMR’s development, including an IPO option. However, the decision regarding an IPO will depend on the results of the study and future funding requirements.“For this fundraising, it will be carried out after the third phase of exploration and all studies are completed, or after 2027,” Ricardo stressed.Expansion Strategy in Mining ServicesWhile continuing exploration of GMR’s gold and copper mine, DEWA is also expanding its mining services business. Not only focusing on PT Kaltim Prima Coal (KPC) and PT Arutmin Indonesia, DEWA is now also providing mining services for PT Sebuku Sejaka Coal (SSC).The new SSC project began operations in August 2026. SSC is a coal mine on Laut Island, South Kalimantan, which can produce up to 5 million tons of coal and 55 million bcm of waste removal, depending on the Work Plan and Budget (RKAB). The estimated volume is equivalent to around 40% of DEWA’s total waste removal volume in 2025.Overall, the estimated value of the SSC contract reaches Rp22 trillion. “We are optimistic that the new contract from Sebuku Sejaka Coal will significantly drive production volume and revenue growth going forward,” Ricardo said.To support its business agenda, DEWA has allocated capital expenditure (capex) of IDR 2.4 trillion for 2026. DEWA had realized capex of IDR 1.5 trillion through the first half of the year, equivalent to 62.5% of this year’s budget.Ricardo said DEWA’s capex this year will be used to support ongoing mining services projects at KPC and PT Arutmin Indonesia. The two major coal mining companies affiliated with PT Bumi Resources Tbk (BUMI) are DEWA’s main customers.The majority of DEWA’s capex is being used to add heavy equipment capacity, spare parts and tires, as well as to support information technology and mine digitalization. In addition to KPC and Arutmin, in the second half of 2026 DEWA will also allocate capex to carry out the contract secured from SSC.“In addition to the remaining capex allocated to KPC and Arutmin, the Company also plans to allocate additional capex separately for Sebuku. The amount and spending at Sebuku will be carried out gradually using several financing options, including vendor financing and other options,” Ricardo said.Beyond KPC, Arutmin, and SSC, DEWA is continuing its expansion in mining services by targeting new contracts. Ricardo said DEWA is exploring new contracts that could maintain the company’s long-term operational performance and revenue prospects.However, Ricardo has yet to disclose further details regarding the potential new contracts. “The Company is currently seeking new long-term contracts, which are expected to increase volume and revenue,” Ricardo said.As part of efforts to strengthen its core business, DEWA recently established three subsidiaries. On July 17, 2026, DEWA established PT DH Listrik, PT DH Infrastruktur, and PT DH Arunika Hospitality.Ricardo explained that the establishment of the three subsidiaries aims to strengthen supporting functions while improving DEWA’s operational effectiveness.“Each will have a different focus and role, namely electricity, infrastructure and logistics, and hospitality to support site operational needs,” Ricardo explained.With more focused management, DEWA can optimize cost efficiency, improve service quality, and strengthen synergies between projects. “For now, this move is part of strengthening the Company’s core business, not an expansion into sectors outside its main business,” Ricardo concluded.

Freeport’s Second Smelter in Gresik to Resume Operations in September 2026
Freeport’s Second Smelter in Gresik to Resume Operations in September 2026
10 Aug 2026, 03:50 PM 87

PT Freeport Indonesia (PTFI) is targeting the Manyar smelter in Gresik, East Java, to resume production in September 2026. PTFI’s second smelter has been shut down since the fourth quarter of last year due to disruptions in concentrate supply following a wet ore mudslide incident in the underground mining area of the Grasberg Block Cave (GBC) on September 8, 2025.PT Freeport Indonesia President Director Tony Wenas said the Manyar smelter is scheduled to resume producing copper cathodes in September 2026.“The smelter will start producing again in September,” Tony said when met in Jakarta, as quoted on Monday (August 10, 2026).According to Tony, copper concentrate from Papua has now begun arriving at the Manyar smelter. However, Freeport is still waiting for sufficient concentrate volumes before operating the furnace at a higher capacity.“For now, the concentrate has started coming in from Papua and has started arriving at Manyar. So perhaps we need to wait until the volume is sufficient before we run it through the furnace,” he said.Tony said the smelter’s operations would not immediately reach full capacity in September. At least initially, the Manyar smelter’s capacity will remain below 30%.He said that by the end of this year, copper ore production capacity from Freeport’s underground mine will only reach around 65% of capacity. Underground mine production is expected to approach 100% by the end of 2027.“Yes, as I said, moving toward 100% by the end of 2027,” he said.For context, PTFI’s smelter is a copper concentrate refining facility located in the JIIPE Special Economic Zone (SEZ) in Manyar, Gresik, East Java. The project, which began construction in October 2021, officially produced its first copper cathode on Monday, September 23, 2024. The first copper cathode production at PT Freeport Indonesia’s second smelter was inaugurated by Indonesia’s seventh President, Joko Widodo.The smelter project, which has the world’s largest single-line design, has a processing capacity of 1.7 million tons of copper concentrate per year and produces around 600,000-700,000 tons of copper cathodes annually.Alongside its first smelter, operated by PT Smelting Gresik, the two smelters owned by PT Freeport Indonesia will refine a total of 3 million tons of copper concentrate per year, producing 1 million tons of copper cathodes, 50 tons of gold, and 200 tons of silver.According to a PTFI report, the cumulative investment in the Manyar smelter project, which occupies 100 hectares in JIIPE, Gresik, East Java, has reached USD 3.7 billion, or IDR 58 trillion.The smelter is equipped with a Refinery Unit, Precious Metals Refining Unit, Oxygen Unit, Sulfuric Acid Unit, and Desalination Unit, as well as an Effluent and Wastewater Treatment Plant, to maximize the utilization of raw materials, by-products, and waste and achieve a high-efficiency smelting and refining process.

Ricardo stressed that for now, the move is part of strengthening the core business, rather than expanding into sectors outside its main business.Gold & Copper Mine ProgressAt the same time, DEWA is working on a gold and copper mining project located in Gayo Lues, Aceh. The project is being developed through PT Gayo Mineral Resources (GMR), which holds a concession spanning 34,500 hectares.Exploration of the GMR gold and copper mine is divided into three stages. The project is currently conducting field work for the second stage, while the third stage is expected to be completed in 2027. However, Ricardo has not disclosed details of the investment value or the schedule and target for starting production at the project.“To make it more optimal and comprehensive, the investment value and production target can be disclosed once the third-stage exploration process and all studies are completed, allowing the Company to maximize the existing potential,” Ricardo said.One of several deposit areas already identified based on the first-stage exploration is located in Tengkereng Atas.

PTBA Proposes BACBIE as Special Economic Zone, Seeks Incentives for Coal-to-DME Project
07 Aug 2026, 05:14 PM 324

PT Bukit Asam (Persero) Tbk, or PTBA, has proposed the Bukit Asam Coal Based Industrial Estate (BACBIE) to be designated as a special economic zone (SEZ). BACBIE is also the site where the Company’s coal-to-dimethyl ether (DME) gasification project will be built.PTBA Vice President of Downstreaming Dahlia Muchtar said the Company proposed BACBIE as an SEZ partly so that all business activities operating in the area can receive special SEZ incentives.“As for the SEZ, it is currently in the application stage, because it is still an industrial estate. The SEZ application is to support coal downstreaming,” Dahlia said when met in South Jakarta on Thursday (Aug. 6, 2026).Dahlia said one of the incentives expected, including for the DME project, is a tax exemption or tax holiday.“Yes, such as a tax holiday, what it will look like. Of course, there will be many goods coming from overseas. That is why we are building BACBIE to support that,” she stressed.DME PartnerOn the occasion, Dahlia said investment partners for the DME project could come from China or the United States (US), with the investment partner to be selected by BPI Danantara.Dahlia stressed that potential partners for the coal downstreaming project remain open, meaning there is potential for partners from other countries to participate in developing the project.However, she stressed that the selection of the partner will be under Danantara’s authority.“There are (potential partners) from the US, and there are from China. So we are still open. Everything remains open; this is currently in the selection stage by Danantara,” Dahlia stressed.For the record, the flagship coal-to-DME downstreaming project had previously failed during the administration of President Joko Widodo. US investor Air Products & Chemicals Inc. (APCI) withdrew from the coal-to-DME project initiated by PTBA in 2023.At the time, the coal-to-DME gasification project was planned to operate for 20 years in the BACBIE area, located at the Tanjung Enim coal mine mouth in South Sumatra. BACBIE was to be located at the same site as the Sumsel 8 Mine Mouth Power Plant.Subsequently, the Energy and Mineral Resources Ministry (ESDM) planned to add new incentives to boost investment in coal downstreaming following the withdrawal of the US investor.The government prepared three coal gasification incentives. First, a 0% royalty specifically for coal processed or converted through gasification. Thermal coal, meanwhile, would remain subject to the applicable royalty rates.Second, an incentive in the form of special coal price arrangements to increase added value or for gasification processes carried out at the mine mouth.Third, an incentive concerning the validity period of coal mining business permits (IUP), which would be granted in accordance with the economic life of the coal gasification industry.For information, PTBA is targeting the coal-to-DME gasification project in Tanjung Enim, South Sumatra, to be completed by 2030, following its groundbreaking on Wednesday (April 29, 2026).PTBA Director of Downstreaming and Product Diversification Turino Yulianto said the investment plan for the coal downstreaming project is being finalized by Danantara.He also confirmed that the project will be developed together with a technology partner, but said he could not disclose the prospective investor as the approach process is still ongoing.The project is targeted for completion in 2030. The investment is being finalized by Danantara. The technology partner is currently in the selection process. It cannot yet be announced,” Turino told Bloomberg Technoz on Tuesday (May 5, 2026).Turino said the prospective technology partners come from several countries, but he declined to provide details on which technology would be used for the DME project in Indonesia.

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.
