Indonesia Is Running Its Nickel Playbook on Rare Earths

Indonesia spent years using resource nationalism to reshape global nickel markets. It banned raw ore exports, forced billions of dollars in domestic smelting investment, and turned itself from a commodity shipper into a processing powerhouse. Now the same institutional machinery is being aimed at rare earths, a mineral category where China holds the kind of dominance over processing that Indonesia once held over unrefined nickel ore.

This is not a junior explorer filing a prospectus. A sovereign government has established a dedicated mineral agency, ring-fenced an entire mineral category under state control, and identified eight priority mining blocks, all within a 12-month window. Indonesia’s nickel playbook is the explicit precedent, and the policy architecture is being assembled in real time.

Here is the analytical framework for understanding what Indonesia is building, where the genuine resource potential sits, and which signals will separate serious execution from policy ambition before the broader market catches up to the story.

The state control blueprint Indonesia is replicating from nickel

The first thing to understand is how deliberately this has been assembled. In 2025, President Prabowo Subianto established the Mineral Industry Agency (Badan Industri Mineral, or BIM), a purpose-built institution to oversee rare earths and other strategic minerals. BIM replaced prior Directorate General roles and was given a mandate that goes well beyond licensing: it steers downstream processing strategy, research coordination, and industrial development. Brian Yuliarto chairs the agency.

The institutional design mirrors Indonesia’s nickel architecture with precision. The Ministry of Energy and Mineral Resources controls upstream raw material supply. BIM controls where the value gets added. That upstream-downstream split is the same logic that forced foreign nickel companies to build smelters on Indonesian soil rather than ship raw ore to China.

Minister Bahlil Lahadalia has publicly declared that rare earths will be managed only by the state, with regulations being finalised to exclude private operators from direct resource control.

The regulations remain in draft form as of August 2026, but the direction is unambiguous. The key entities and their roles are worth mapping for orientation:

• BIM: Mineral Industry Agency steering downstream strategy and research; chaired by Brian Yuliarto
• Ministry of Energy and Mineral Resources: Controls upstream supply, permitting, and raw material policy
• Perminas (PT Perusahaan Mineral Nasional): State-owned company holding the first rare earth mining permits
• PT Timah Tbk (TINS): State-linked tin producer advancing rare earth processing in Bangka Belitung

For investors who tracked how Indonesia’s nickel export bans forced a restructuring of global supply chains, the institutional logic here is familiar. The question is no longer whether Indonesia intends to control the rare earth value chain. The question is whether the geology and processing capability exist to make that intention real.

Indonesia’s nickel supply chain restructuring offers the clearest precedent here: quota mechanisms and domestic processing mandates pushed Chinese smelting investment onshore and redirected global flows within a few years of the export ban taking effect.

Eight blocks, three regions, and what the geology actually signals

The government identified eight priority blocks with rare earth potential in February 2026, distributed across three regions. Each cluster has a distinct geological rationale.

The four Bangka Belitung blocks sit on tin-mining geology, which matters because monazite, a rare earth-bearing mineral, concentrates naturally in tin tailings. That co-location with existing mining infrastructure gives those blocks a near-term pathway that purely greenfield sites lack.

Mamuju in West Sulawesi is the block most frequently highlighted for heavy rare earth potential, the subset of rare earths most critical for permanent magnets used in electric vehicles and wind turbines. Bombana carries both rare earth and antimony potential, but partially overlaps with protected forest areas, creating permitting complexity that could delay development significantly.

Reported grades run in the range of approximately 2,000-2,391 ppm REE across several blocks. National rare earth potential is estimated at approximately 350,000 tons REO, though this figure requires further verification. No JORC-style resource statements (independently verified estimates of tonnage and grade classified by confidence level) have been publicly disclosed for any of the eight blocks.

JORC resource classification converts geological potential into a format that investors and lenders can price: without Inferred, Indicated, or Measured estimates from a qualified person, block-level tonnage and grade figures carry no regulatory standing and no financing weight.

Where the first permits have actually landed

The only hard evidence of upstream progress sits in Mamuju. In April 2026, the Ministry of Energy and Mineral Resources issued two rare earth mining business permits (IUPs) to Perminas, covering the Botteng and Takandeang blocks. These permits, based on proposals from the Geological Agency, are the first upstream titles explicitly framed as rare earth mines.

Exploration coverage remains limited, with only a small fraction of prospective Mamuju areas detailed to date. The two Perminas permits are the line between identified potential and actual project development. Everything else on the eight-block list sits firmly on the prospective side of that line.

The processing gap that will determine whether this becomes an industry

Mining rare earth ore is not the hard part. Separating and refining rare earths into the individual oxide products that manufacturers need is where China has built its dominance, and it is where Indonesia faces its most significant challenge. Indonesian policymakers explicitly acknowledge this.

BIM has stated that processing, not mining, is the priority bottleneck for Indonesia’s rare earth ambitions, and that the agency will launch two research programmes focused on separation and refining technologies.

Indonesia currently has no large-scale separation plants or commercial-scale refining capacity. What it does have are two parallel processing tracks, each at a different stage of development:

Rare earth processing bottlenecks are not unique to Indonesia; globally, separation and refining capacity outside China remains severely constrained, with most projects outside the Chinese system still years from commercial-scale output.

1. Lampung “total extraction” R&D programme: Anchored at the Iskandar Zulkarnain Science and Technology Area in Lampung, this initiative aims to develop industrial-scale extraction technology for rare earth elements and associated radioactive minerals. A memorandum of understanding was signed in May 2026 to coordinate research across rare earths, radioactive minerals, and other strategic resources. This is the more ambitious, longer-dated track.
2. PT Timah’s Tanjung Ular facility, Bangka Belitung: PT Timah Tbk (TINS), in partnership with Perminas, is advancing a rare earth research and production facility with groundbreaking targeted for 20 May 2026. The feedstock strategy is pragmatic: recover monazite from tin mining tailings rather than develop new mines from scratch.

The Bangka Belitung tailings route is the more credible near-term pathway precisely because it does not require Indonesia to solve rare earth mining and rare earth processing simultaneously. Tin tailings already exist in quantity, and the monazite they contain is a known rare earth feedstock. The Lampung programme, by contrast, is pursuing technology that would need to work at industrial scale on ore types that have not yet been characterised to commercial standards.

For investors tracking whether Indonesia can close the processing gap, the Bangka Belitung track is the one to watch in the near term. If that facility produces even small volumes of separated rare earth products, it would represent a meaningful proof of concept.

What serious execution looks like from here, and what signals to watch

Indonesia’s rare earth sector is pre-commercial. The value here is optionality, not near-term cash flow, and the development path will be measured in years, not quarters. Indonesia is positioning for a potential 1-5% role in global rare earth supply long-term, with meaningful contribution unlikely before 2030. Current contribution is negligible.

That does not make the story irrelevant. It means the analytical framework needs to shift from “what has happened” to “what would confirm this is real.”

The five signals that separate execution from ambition

For investors already holding exposure to the global rare earth supply chain thematic, Indonesia is now a jurisdiction to model into long-range scenarios rather than act on immediately. These are the five categories of signals that will indicate whether policy architecture is translating into executable projects:

Critical minerals supply chain vulnerabilities have prompted Western governments to accelerate offtake commitments and processing investments outside China, creating the geopolitical tailwind that gives Indonesia’s rare earth ambitions a receptive international audience.

• Resource Definition: Publication of formal JORC-style resource statements for any of the eight blocks. Without independently verified tonnage and grade estimates, these blocks remain geological potential rather than mineable resources.
• Permitting: Expansion of IUPs beyond Botteng and Takandeang. Resolution of protected forest overlaps, particularly in Bombana, will signal whether the government is willing to spend political capital on clearing regulatory friction.
• Processing Partnerships: Foreign joint ventures or technology licensing deals, particularly involving Chinese, Japanese, Korean, or Australian partners. Processing technology is the single largest gap; a credible foreign partnership would compress the timeline significantly.
• Regulatory Clarity: Final rules on state control, the role of private and foreign investors in joint ventures or downstream projects, and export rules for rare earth concentrates, particularly where naturally occurring radioactive mineral associations are involved.
• Budget and Political Follow-Through: Sustained BIM funding and staffing beyond initial announcements. Integration of rare earth initiatives into broader national EV and clean energy strategies. The 2030 downstream value targets referenced in agency planning need budget backing to remain credible.

The signal that changes the calculus from “watch” to “act” is either a foreign processing partnership announcement or the first JORC-compliant resource statement from one of the eight blocks. Either would convert a policy story into a project story.

Indonesia’s rare earth window is open, but the clock is not yet running

Indonesia has assembled the institutional architecture, identified the resource base, and articulated a processing strategy. What it has not done is close the gap between policy design and commercial output. The architecture is real; the production is not.

The global rare earth market remains dominated by China in both mining and processing. Indonesia is adding prospective supply from a jurisdiction with established mining experience in nickel, coal, and tin, with existing logistics and regulatory frameworks, and a proven resource-nationalist playbook that has already reshaped one global commodity market.

President Prabowo Subianto has publicly called for accelerating the use of critical minerals, including rare earths, to support national industrialisation and EV development, reinforcing that this is a political and economic priority rather than a peripheral project.

Two structural friction points could slow execution: the radioactive mineral associations common in Indonesian rare earth deposits, which complicate processing and export permitting, and the protected forest overlaps that affect at least one priority block. Whether Indonesia can navigate both quickly enough to become a meaningful supply chain contributor before the energy transition’s critical mineral demand peaks is the question that gives this story its forward tension.

The radioactive byproduct regulations in rare earth mining vary significantly across jurisdictions, and Indonesia’s monazite-bearing deposits carry thorium and uranium associations that complicate both domestic processing approvals and export permitting under international standards.

The next 24-36 months will determine whether Indonesia’s rare earth ambitions follow the nickel precedent, where policy architecture eventually delivered real supply chain disruption, or remain a well-designed programme waiting for the processing technology and permitting clarity to catch up. For investors in the rare earth thematic, this is the jurisdiction to add to the watch list now, before the broader market assigns it a price.
