BUMI’s Gold Project in Australia Moves Faster, Benefiting the Company
BUMI’s Gold Project in Australia Moves Faster, Benefiting the Company
08 Jul 2026, 01:49 PM 800

PT Bumi Resources Tbk (BUMI) has once again recorded positive developments in its business diversification strategy.The company’s Australian subsidiary, Wolfram Limited, announced that the development of the Mt. Carlton mining project in Queensland is progressing ahead of schedule, marked by the commencement of underground mining activities and access to higher-grade ore.The development was announced after Queensland Minister for Mining, Hon. Dale Last MP, officially reopened operations at the Mt. Carlton project on June 30, 2026.The inauguration marked an important milestone in reviving one of the region’s largest gold, silver, and copper assets.BUMI explained that since April 2026, open-pit mining activities in the V2 area have become the main source of production for the Mt. Carlton project.The extracted ore is processed on-site before being shipped in concentrate form to Glencore under a seven-year offtake agreement.The project has now reached another milestone with the commencement of underground mining activities in the A39 area.The operation is producing higher-grade ore, which is expected to improve Wolfram’s production profile in the coming periods.Analysts said the accelerated development of the project indicates that operational execution is progressing in line with, or even ahead of, the initial plan.The start of underground operations is also considered to open opportunities for improved production quality, as the company begins gaining access to higher-grade ore reserves.“The entry into underground operations is an important milestone as it shows the project is developing faster than the target. Access to high-grade ore has the potential to increase productivity while providing leverage to operating margins amid a commodity price outlook that remains promising,” said Cliff Nathaniel, an analyst at Panin Sekuritas.According to Cliff, developments at Mt. Carlton further strengthen BUMI’s transformation from a company historically associated with coal into a natural resources company with broader exposure to precious and base metals such as gold, silver, and copper.“We view this diversification as strategically valuable because it can reduce dependence on the coal cycle. As the contribution from metal assets increases, BUMI’s revenue and profit profile has the potential to become more balanced and resilient over the long term,” the analyst said.In addition to providing an additional source of growth, analysts noted that the seven-year concentrate sales contract with Glencore also provides greater visibility for marketing production output.This is considered capable of reducing commercial risks during the early stages of project development while supporting the sustainability of operational cash flows.“Going forward, the market will monitor the potential increase in production volumes from underground mining, the realization of concentrate shipments, and the scale of Mt. Carlton’s contribution to BUMI’s consolidated performance,” Cliff said.With several milestones achieved ahead of schedule, the Wolfram project is considered to further strengthen BUMI’s long-term prospects while demonstrating that the company’s diversification strategy is beginning to deliver tangible results.

PT Vale has also developed a Reduce, Reuse, Recycle Waste Processing Facility (TPS3R) as part of its sustainable waste management efforts.With these achievements, PT Vale emphasized that the IGP Sorlim project continues to move forward by prioritizing sustainability principles while delivering benefits to communities and the environment surrounding its operational areas.

AMMN Enters New Growth Cycle, Revenue Projected to Surge 117%
AMMN Enters New Growth Cycle, Revenue Projected to Surge 117%
02 Jul 2026, 09:24 AM 1581

PT Amman Mineral Internasional Tbk (AMMN) is projected to enter a new growth cycle this year. This follows the conclusion of the operational transition period throughout 2025, opening the way for stronger performance growth.According to BRI Danareksa Sekuritas' latest research published on June 29, 2026, AMMN is at the beginning of a new growth cycle, supported by increased production from the Batu Hijau Phase 8 mine and contributions from its downstream business, which has begun producing higher value-added metal products."AMMN is entering a significant earnings growth cycle in 2026 after completing the Batu Hijau Phase 8 development transition," BRI Danareksa Sekuritas analyst Andhika Audrey Eko Nugroho said in the report, as quoted on Thursday (July 2, 2026).Andhika explained that signs of the recovery were evident in the first quarter of 2026, when fresh ore mined increased to 38 million tonnes, compared with around 1 million tonnes in the same period a year earlier.This drove concentrate production to 167.8 thousand dry metric tonnes (dmt), up 110 percent year-on-year. The output contained around 101 million pounds of copper and 136 thousand ounces of gold.As a result, he said, the recovery in Batu Hijau production is expected to be one of the main drivers of AMMN's performance growth throughout 2026. The company's revenue is projected to reach around USD 4 billion this year, up 117 percent from the previous year, while EBITDA is forecast to grow 97 percent to around USD 2 billion."Besides the recovery in mining production, business transformation through downstream processing is considered an important factor that will improve the quality of AMMN's earnings over the long term," he said.In the first quarter of 2026, AMMN's smelter and Precious Metal Refinery (PMR) facilities produced around 27.7 thousand tonnes of copper cathodes and 66.2 thousand ounces of refined gold.According to him, AMMN is now transforming from a company that previously sold concentrate into an integrated metals producer manufacturing end products in the form of copper cathodes and refined gold that meet international standards. This transformation is considered to generate higher added value while strengthening the company's resilience against changes in the global mining industry.Starting in the second quarter of 2026, following the expiry of its concentrate export permit in April 2026, AMMN's performance is expected to be driven by sales of copper cathodes and refined gold.Furthermore, Andhika said, BRI Danareksa also highlighted the company's new processing facility project, which is currently in the final stage of construction. The facility is scheduled to receive its first ore in the second half of this year and will increase processing capacity from around 40 million tonnes per year to around 85 million tonnes per year."The increase in capacity is expected to support production volume growth over the next several years, both to sustain Batu Hijau operations and the development of the Elang project as the company's long-term growth driver," he said.Over the medium term, he said, copper cathode production is projected to continue increasing in line with higher smelter utilisation, while refined gold production is also expected to grow significantly as the PMR reaches optimal operations.Beyond the company's internal factors, BRI Danareksa believes the outlook for the global copper market remains highly attractive over the next several years.Copper demand is now no longer dependent solely on the construction sector, but is increasingly driven by electrification trends, the development of artificial intelligence (AI)-based data centres, electric vehicles, and renewable energy infrastructure.At the same time, global supply growth is considered to remain limited, leaving the copper market expected to stay in deficit in both the short and long term.Meanwhile, gold prices are also being supported by strong demand from central banks around the world, which continue to increase their holdings of the precious metal as part of their foreign exchange reserve diversification strategies."With the combination of Batu Hijau's operational recovery, the growing contribution from downstream processing, the nearly completed expansion project, and the positive outlook for the company's main commodities, AMMN is considered to be in a strong position to enter its next phase of growth," he said.BRI Danareksa Sekuritas initiated coverage of AMMN with a "Buy" recommendation and a target price of IDR 6,000 per share.

01 Jul 2026, 10:22 AM 1641

PT Trimegah Bangun Persada Tbk (NCKL), or Harita Nickel, is accelerating the completion of three strategic projects in the Obi Island Industrial Estate, North Maluku.The three main projects include the third Rotary Kiln Electric Furnace (RKEF) nickel processing facility, a limestone processing plant to produce quicklime, and a tailings recycling facility.NCKL President Director Roy Arman Arfandy said the third RKEF smelter project, developed through its subsidiary PT Karunia Permai Sentosa (KPS), consists of 12 production lines with an installed capacity of 185,000 tonnes of nickel metal in the form of ferronickel (FeNi) per year."KPS is our third RKEF plant. It is currently in the finalisation process," he said during an online public expose on Tuesday (June 30, 2026).The company completed the construction of 10 production lines throughout 2025. Meanwhile, the construction of the final two production lines was completed in the first quarter of 2026, marking the completion of the entire physical construction phase of the plant's main facilities.Currently, management has begun gradual operational ramp-up at several production lines towards full operational capacity.Roy said the company targets all 12 production lines under KPS to operate at full capacity by the end of this year.Meanwhile, additional supply from KPS is projected to increase Harita Nickel’s accumulated installed ferronickel capacity on Obi Island to 305,000 tonnes of nickel per year by the end of 2026. The portfolio complements the company’s two existing processing facilities, which had already reached full operations.For information, the company’s first smelting facility is operated through PT Megah Surya Pertiwi (MSP), with a production capacity of 25,000 tonnes of nickel per year.Furthermore, PT Halmahera Jaya Feronikel (HJF) operates eight fully operational production lines with an installed capacity of 95,000 tonnes of nickel per year.In addition to increasing ferronickel output, Harita Nickel is accelerating the development of integrated supporting projects to reduce reliance on external costs.One of these projects is the construction of a quicklime plant through joint venture company PT Cipta Kemakmuran Mitra (CKM).The entity is responsible for producing quicklime, a key chemical component supporting the refining process of low-grade nickel ore (limonite) at High-Pressure Acid Leach (HPAL)-based hydrometallurgical facilities."CKM will produce quicklime to be used in the HPAL process at both PT Halmahera Persada Lygend and Obi Nickel Cobalt, both of which are HPAL plants that we already operate on Obi Island," Roy said.The output from one CKM production line will be directly allocated to supply the operational needs of the company’s two existing HPAL facilities operated by its subsidiaries, namely PT Halmahera Persada Lygend (HPL) and PT Obi Nickel Cobalt (ONC).
