Hunan lithium resource discovery lifts China’s LCE outlook

Hunan lithium

Revised deposit metrics and strategic context

The Hunan lithium resource discovery adds a 49mn-tonne lepidolite deposit in Linwu. Authorities estimate 1.31mn t lithium oxide, or 3.24mn t LCE. The ore also contains rubidium, tungsten, and tin. Therefore, the Hunan lithium resource discovery broadens China’s battery raw material base.

Revised national resources and project pipeline

China’s lithium resource estimate now stands at 16.5% of global resources. Revisions reflect new finds in Sichuan, Xinjiang, Qinghai, Jiangxi, Inner Mongolia, and Hunan. Meanwhile, officials still rank China second globally, behind Bolivia. As a result, the Hunan lithium resource discovery strengthens supply diversification across provinces.

Dazhong Mining investments and timeline

Inner Mongolia Dazhong Mining is building integrated mining and processing in Hunan. The 16bn-yuan plan includes ore, lithium carbonate, CAM, and battery plants. Phase one targets 10mn t per year ore and 20,000 t per year lithium carbonate in 2026. Additionally, Dazhong owns the Jiada spodumene asset in Sichuan with 1.48mn t LCE.

This discovery could influence lepidolite processing economics and domestic supply security. Granite-type lepidolite requires energy, reagents, and recovery optimization. However, co-products may offset costs and improve project viability. Therefore, downstream cathode producers could hedge against imported feedstock volatility.

The Metalnomist Commentary

Large lepidolite resources can reshape China’s midstream flexibility if recoveries scale competitively. Execution will hinge on beneficiation yields, reagent costs, and ESG standards. Watch Dazhong’s commissioning cadence and LCE conversion routes through 2026.
