Antam Nickel Ore Output Surges as Indonesia’s Domestic Demand Drives Growth

Antam Nickel

Antam nickel ore output surged in 2025 to its highest level in more than a decade. The state-controlled miner produced 16.1mn wet metric tonnes of nickel ore. That was up 62pc from the previous year. As a result, Antam nickel ore output now reflects the strength of Indonesian domestic nickel demand.

The company’s sales performance was even stronger. Nickel ore sales rose 75pc year on year to 14.6mn wet metric tonnes. This shows that domestic downstream buyers absorbed much of the additional supply. Therefore, Indonesia nickel ore production continues to benefit from the country’s internal processing expansion.

This matters because Antam’s ore supports more than one value chain. Its nickel ore feeds domestic class two nickel production and the company’s own ferronickel operations at Kolaka. Consequently, Antam nickel ore output remains important to both external downstream users and its internal processing strategy.

Indonesian Domestic Nickel Demand Is Reshaping Antam’s Business Mix

Indonesian domestic nickel demand is clearly driving Antam’s ore growth. The company’s production surge shows how strongly local processors continue to pull feedstock into the domestic market. This supports Indonesia’s long-term policy of deeper downstream integration. As a result, ore production is becoming more strategically valuable than before.

However, Antam’s ferronickel business moved in the opposite direction. Ferronickel output fell 20pc to 16,064t in nickel metal equivalent. Sales almost halved to 10,528t in nickel over the same period. Therefore, Antam is seeing a widening gap between ore strength and ferronickel weakness.

The company said rule changes in minimum sales pricing largely caused that decline. That means the problem was not simply demand destruction. Instead, market rules affected the economics of ferronickel sales more directly. Meanwhile, all ferronickel sales were exported, mainly to South Korea, India, and China.

Antam Battery Ecosystem Project Adds a New Strategic Layer

The Antam battery ecosystem project gives the company a stronger long-term growth story. Its joint venture with CATL began construction in the fourth quarter of 2025. That project aligns with Indonesia’s ambition to build a full downstream EV battery chain. Consequently, Antam is linking ore production more directly to higher-value battery materials.

This development matters because it expands Antam’s role beyond mining and traditional nickel products. The company is now tied more closely to Indonesia’s battery industrialization strategy. That could improve its strategic relevance even if ferronickel remains under pressure. Therefore, the Antam battery ecosystem project may become more important than short-term alloy sales.

The broader message is clear. Antam nickel ore output is rising because Indonesia’s downstream nickel model still demands more feedstock. At the same time, product mix and pricing rules are shifting value across the chain. As a result, Antam’s future may depend more on ore and battery exposure than on ferronickel alone.

The Metalnomist Commentary

Antam’s results show how Indonesia’s nickel strategy is rewarding upstream ore suppliers tied to domestic processing. The weakness in ferronickel also shows that not every downstream segment benefits equally. If the battery ecosystem expands as planned, Antam could become even more central to Indonesia’s next nickel phase.
