China Rare Earth Resources Expand as Maoniuping REO Estimate Nearly Doubles

China Natural Resources

China rare earth resources have received another major boost after the natural resources ministry confirmed 9.67 million tonnes of rare earth oxide resources at the Maoniuping mining area in Sichuan province. The updated estimate nearly doubles the 4.96 million tonnes of REO previously reported by China Rare Earth Group in September 2024.

The Maoniuping mine is operated by China Rare Earth Group, the country’s largest state-owned rare earth producer. The new resource verification strengthens China’s upstream position in a sector where it already dominates separation, refining, magnet materials, and downstream industrial applications.

China rare earth resources remain central to global supply chains for electric vehicles, wind turbines, defense systems, robotics, electronics, and advanced manufacturing. The larger Maoniuping resource base gives Beijing more long-term optionality as rare earth demand rises and geopolitical competition intensifies.

Maoniuping Reinforces China’s Rare Earth Industrial Advantage

The Maoniuping update is strategically important because China’s rare earth strength is not limited to mining. The country controls the most advanced and integrated rare earth processing system, from ore extraction to separated oxides, metals, alloys, and permanent magnets.

A larger confirmed REO resource base supports that industrial chain. It gives China Rare Earth Group a stronger reserve platform and reinforces Beijing’s ability to manage supply, pricing, and export policy across rare earth markets.

The timing also matters. China has pledged to launch a new round of mineral exploration actions over the next five years, aiming for breakthroughs in strategic resources. The Maoniuping result shows how exploration and state-backed consolidation are working together to protect China rare earth resources and industrial competitiveness.

Antimony Discovery Adds Weight to Strategic Mineral Policy

China also confirmed antimony resources equivalent to 51,455 tonnes of metal at the Waxigou mine in Gansu province. The project is held by Gansu Sanchang Mining and adds another resource point in a market already affected by tight supply and export controls.

Antimony has become more strategically visible because it is used in flame retardants, alloys, semiconductors, ammunition, and defense-related applications. China accounts for a dominant share of global refining capacity, making any new domestic resource confirmation important for both supply security and policy leverage.

Beijing has already placed antimony and rare earths under stricter dual-use export licensing controls. As a result, ex-China supply has tightened, prices have surged, and overseas buyers are reassessing dependence on Chinese-controlled critical mineral chains.

The Metalnomist Commentary

China’s latest rare earth and antimony confirmations show that Beijing is strengthening both the upstream and regulatory sides of critical mineral control. For the US, EU, Japan, and Korea, the message is clear: diversification must include mining, refining, recycling, and advanced material production, not just alternative offtake contracts.
