Aim-listed Andrada Mining, formerly AfriTin Mining, has received further results from the lithium and tantalum infill drilling programme at its flagship operation, the Uis mine, in Namibia.
Pegmatite was intersected in all holes at the depths and apparent widths predicted by the geological model.
The programme is aimed at upgrading the existing lithium and tantalum mineral resource.
The update entails the results of 14 drill holes. These results increase the total number of holes reported on to 49 of the 50-hole drilling programme.
The programme comprised 29 diamond and 21 reverse circulation (RC) drill holes. The aim of the programme is to increase the confidence of the existing lithium and tantalum mineral resource estimates in the V1/V2 pegmatite.
The pegmatite intersections reported in the update align with the current geological model, confirming its spatial accuracy.
The drill holes intersected the pegmatite at shallow depths where the V1 and V2 bodies have bifurcated into individual units, as well as at greater depths where the units coalesce into a single pegmatite, while drill holes V1V2058 and V1V2080 were stopped within the pegmatite and do not represent the full intersection.
The dip angle of the pegmatites varies from 24° to 48° and the majority of the reported drill holes are orientated vertically such that the reported intersections represent apparent thickness.
Holes V1V12050, V1V12051 and V1V12034 are inclined and intersected the pegmatite at about right angles.
“As we continue to report on the drilling programme results, I am pleased that they further highlight the mineralisation potential of the V1/V2 pegmatite orebody. The additional 14 holes being reported on in this announcement are located in the centre of the pegmatite and show that the potential lithium, tin, and tantalum mineralisation continues at depth.
“The higher lithium grades of up to 1.43% lithium oxide are particularly exciting because they further demonstrate the unrealised potential of the V1/V2 orebody and support the early development of a lithium processing plant,” CEO Anthony Viljoen comments.
