Andrada Mining announces significant lithium resource upgrade at its Uis mine

Highlights:

• Updated MRE for the V1/V2 deposit with lithium and tantalum upgraded to a measured and indicated classification as a result of infill drilling.
• Lithium average grade has increased to 0.73% Li₂0 from 0.63% L_i2O declared in 2019, total contained Li₂O tonnes have increased by 30% to 587 000 t.
• Updated resource gives a lithium carbonate equivalent of 1.45 million t.
• The measured and indicated lithium resources increased by 47% to 38 million t.
• Tin average grade has increased to 0.15% Sn from a previous average of 0.134% Sn, resulting in contained tin metal content of 120 000 t.
• Maiden resource declared for rubidium with a contained total of 109 400 t at an average grade of 0.14% Rb.
• Total MRE for the V1/V2 deposit inclusive of mining depletion has increased to 81 million t from 72 million t.

Anthony Viljoen (CEO), commented:

“I am very pleased to announce a new enlarged lithium resource at our Uis Mine in Namibia following significant drilling programme in 2022. This confirms our belief that Uis is a globally significant lithium and tin resource that remains open at depth and is one of over 180 mineralised pegmatites within 5 km of the Uis processing facility. The drilling programme has exceeded our expectations, delivering higher grades, and has increased the overall tonnage by 13% when compared to the previous resource estimate from 2019 and 30% more contained lithium. The updated mineral resource estimate is solely from V1/V2 pegmatite, which clearly highlights the significant untapped potential of the wider Uis pegmatite swarm across our licence area.

“This MRE has been delivered ahead of our lithium pilot plant commissioning which is due to come online in 2Q23 and is an important step to realise the additional lithium and tantalum revenue streams alongside our tin production. This new resource will increase the economics for Andrada and will form the basis for the next phase of expansion and growth for the Uis mine.

“The next phase of exploration will investigate the other proximal pegmatites at Uis with the end goal of repeating this process and ultimately expand the resource at Uis to achieve the exploration target of 200 million t.”
