The lithium at the Uis mine occurs predominantly as petalite (a lithium aluminum silicate mineral), and the company has successfully produced high-purity petalite concentrate through their pilot and bulk sampling efforts:
As early as 2023, they commissioned a lithium pilot plant and produced initial batches of saleable lithium (petalite) concentrate—starting with small amounts like 10 tonnes for testing and offtake discussions.
They later operated a bulk lithium sampling plant (adjacent to the main tin plant) to produce petalite concentrate samples for further testing, optimization, and engagement with potential buyers. Reports from 2024–2025 confirm ongoing production of high-purity petalite concentrate from this setup, the integration of lithium circuit to the tin tantalum circuit is possibly a lot easier than many people think.
