Indonesia reached USD 6.7 billion in mineral investments in 2025, reflecting the aggressive push to upgrade its mineral sector through downstream development and value-added production. The government prioritized the completion of several national strategic projects to accelerate the transition from exporting raw materials to producing refined products for high-growth industries, including electric vehicle batteries and energy transition technologies. The Ministry of Energy and Mineral Resources reported that strong mineral investment helped reinforce economic growth and industrial transformation.
Indonesia Mineral Investment Surges on Downstream Strategy
Indonesia accelerated its downstream strategy by pushing major mineral projects across nickel, alumina, and tin. The state mining holding MIND ID advanced several large nickel developments through PT Vale Indonesia’s Indonesia Growth Project portfolio in Sorowako Limonite, Morowali, and Pomalaa.
Collectively, these projects carried an estimated investment value of 8.7 billion USD. The government considers downstream nickel capacity essential for positioning Indonesia within emerging supply chains for electric vehicles and renewable technology. Industry experts argued that this shift away from raw mineral exports reflects a broader commitment to value-added production.
According to the Indonesia Mining Institute Chairman Irwandi Arif, “Downstreaming allows Indonesia to move away from exporting raw materials toward high-value-added products, while strengthening Indonesia’s role in supporting global energy transition.” He noted that Indonesia must also improve exploration to sustain long-term mineral reserves and competitiveness.
Indonesia Mineral Investment Supports Nickel and Battery Supply Chains
Nickel has become central to Indonesia’s attempts to embed itself within EV battery supply chains. The completion of new nickel smelters and refineries enables domestic producers to deliver key intermediate products for battery manufacturing rather than relying on export-driven trade. Consequently, Indonesia deepens its participation in the global shift toward cleaner technologies.
PT Freeport Indonesia also expanded downstream capacity by developing a precious metal refinery in Gresik, East Java, with an investment value of about 630 million USD. The facility will refine anode slime into higher-value products, including gold and silver. This development aligns with efforts to move Indonesia closer to full-cycle industrial production in the mining sector.
Private Sector Participation Expands Critical Minerals Capacity
Private sector participation increased as tin-based downstream plants entered operation in Batam. PT Solder Tin Andalan Indonesia invested roughly 400 billion Rupiah to establish a tin processing facility capable of producing industrial intermediates. PT Batam Timah Sinergi followed with a one trillion Rupiah investment in a downstream tin plant that produces stannic chloride, dimethyl tin dichloride, and methyl tin mercaptide for manufacturing applications.
Industry analysts observed that private sector participation balances state-led initiatives and broadens Indonesia’s mineral base beyond nickel. Growth in tin, alumina, and precious metals enables Indonesia to diversify its mineral resources while attracting foreign capital into supply chains that serve both domestic and export markets.
Energy Transition Minerals Strengthen Indonesia’s Competitive Position
Experts argued that critical minerals increasingly support Indonesia’s ability to compete in the global energy transition. As Irwandi noted, Indonesia faces “a fundamental challenge to increase exploration activity to maintain reserve sustainability and long-term competitiveness.” The call for more exploration coincides with rising demand for critical minerals related to decarbonization and electrification.
However, some analysts voiced caution over potential production restrictions. Indonesia Mining and Energy Watch Executive Director Ferdy Hasiman said, “We expect mineral investments to grow further to support the government’s economic targets. However, production limits could affect the sector’s performance.” He added that restrictions may also drive commodity prices higher and encourage private sector participation as the main engine of investment.
Downstreaming Expected to Drive Future Investments
Indonesia enters the coming years with a clearer industrial direction. Downstreaming strengthens mineral value chains, attracts investment, and integrates Indonesia into strategic industries such as EV batteries and renewable technology. Although challenges persist, including reserve sustainability, price volatility, and regulatory limits, market fundamentals remain favorable.
The government expects further investment inflows as ongoing national strategic projects transition from construction to operation. Private sector activity is also likely to increase as critical minerals gain prominence in global manufacturing. Together, these dynamics reinforce Indonesia’s evolution from a raw material exporter to a producer of high-value-added mineral products that support the world’s shift toward cleaner energy systems.
