Name of the Project
Uis lithium expansion project.

Location
Erongo region, Namibia.

Project Owner/s
Critical raw materials producer Andrada Mining through its subsidiary Uis Tin Mining Company (UTMC).

Project Description
The Uis mine exploits a polymetallic pegmatite-hosted deposit containing tin, tantalum and lithium mineralisation. The mine currently produces tin and tantalum concentrates.

Andrada intends to monetise the lithium contained in the run-of-mine by building a beneficiation circuit that is integrated into the tin and tantalum processing facility of the Uis mine. 

The additional integrated circuit will not increase the ore requirements from the mining operation but will rather reprocess the waste material from the tin and tantalum concentrator for lithium enrichment. 

Lithium mineralisation predominantly occurs as petalite. During the initial phase, petalite concentrate will be produced for the technical lithium market at an initial target of 50 000 t/y. 

Previous feasibility studies towards this initial phase, have advanced the project to a prefeasibility level of confidence. 

Andrada envisages a second phase of development aimed at supplying the lithium refining industry with concentrate for producing lithium chemicals for the fast-growing battery industry.

Potential Job Creation

Net Present Value/Internal Rate of Return
Not stated.

Capital Expenditure
Andrada Mining entered into a $2.5-million secured funding facility from LC Abelheim as trustee of The Orange Trust in February 2025. The Orange Trust is Andrada’s largest shareholder, with 15.81% of the issued ordinary shares in the company.

Planned Start/End Date
Not confirmed.

Latest Developments
Andrada Mining’s Namibia subsidiary, Uis Tin Mining, has extended its offtake agreement with Thaisarco, granting the smelter exclusive rights to all tin concentrate produced at Uis for the term of the agreement. In exchange, Thaisarco will advance $3-million (expected imminently) to support liquidity as operations scale up. The advance is unsecured, interest-free, repaid at Uis’ discretion (outside default scenarios), with a small marketing discount applied to future sales.

Separately, Andrada has signed a cooperation agreement with the European Investment Bank to accelerate the feasibility study for its Uis lithium expansion, with EU-funded technical and project development assistance intended to move the project to bankable feasibility.
