Lithium and Tantalum Infill Drill Programme Update

AfriTin Mining Limited (AIM: ATM), an African technology metals mining company with a portfolio of mining and exploration assets in Namibia, announces further results from the lithium and tantalum drilling programme at the Company's flagship operation, the Uis Mine ("Uis").

The 50-hole drilling programme, comprising 29 diamond and 21 reverse circulation (RC) drill holes, aims to increase the confidence of the existing lithium and tantalum mineral resource estimates over the deposit. All 50 drill holes have been completed and are being processed. The results of 25 previous holes were announced on 8 June 2022, 20 July 2022, 10 October 2022 and 22 November 2022. This announcement reports the assay results of the next 5 drill holes (Figure 1). The results of the outstanding 20 drill holes will be provided once received.

Highlights:

·      Pegmatite was intersected in all holes at depths and apparent widths predicted by the geological model;

·      Significant pegmatite intersections include:

o  90 m at 0.164% Sn, 73 ppm Ta, and 1.40% Li₂O from 134 m to 224 m; and 12 m at 0.159% Sn, 182 ppm Ta, and 0.59% Li₂O from 115 m to 127 m for drill hole V1V2062;

o  96 m at 0.150% Sn, 68 ppm Ta and 0.72% Li₂O from 142 m to 238 m for hole V1V2039;

o  71 m at 0.166% Sn, 81 ppm Ta, and 1.05% Li₂O from 157 m to 228 m; and 10 m at 0.091% Sn, 323 ppm Ta and 0.41% Li₂O from 139 m to 149 m for drill hole V1V2065;

·      These results include some of the drilling programme's most notable intersections of lithium mineralisation within the pegmatite intersections:

o  76 m at 1.56% Li₂O from 136 m to 212 m for drill hole V1V2062;

o  26 m at 1.00% Li₂O from 180 m to 206 m for drill hole V1V2039; and

o  25 m at 1.65% Li₂O from 193 m to 218 m for drill hole V1V2065.

Anthony Viljoen (CEO) commented:

"These exploration drill results contain the highest average lithium grade for a full pegmatite intersection within the V1/V2 pegmatite ore body to date, namely 90m at an average Li₂O content of 1.40%. This intersection includes a continuous portion of 76 m at 1.56% Li₂O. The lithium grade of the V1/V2 pegmatite appears to increase with depth, and the Company intends to further explore the down dip potential of this pegmatite. We look forward to the potential upgrade of our mineral resource estimate and advancing our lithium and tantalum product development programmes at Uis."

Exploration Programme

The current exploration programme aims to upgrade the existing resource classification for lithium and tantalum over the areas where tin is currently classified within the measured and indicated categories for the 2019 JORC (2012) compliant mineral resource estimate (MRE) (see announcement dated 16 September 2019). The pegmatite intersections of the reported holes 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 greater depths where the units have coalesced. The dip angle of the pegmatites varies from 24 degrees to 48 degrees and the drill holes are orientated vertically such that reported intersections represent apparent thickness.

Drill hole V1V2039 deflected towards the west while drilling and as a result the hole was terminated within ore to avoid superfluous drilling down the dip of the pegmatite. The deeper drill holes from this programme appear to intersect greater volumes of pegmatite, and these deeper extensions may also contain higher lithium grades as indicated below.

Table1: Exploration results of RC drill holes V1V2060, V1V2062, V1V2039, V1V2065, and V1V2029 indicating the full pegmatite intersection and pegmatite grades as well as selected higher grades within the pegmatites as per the highlights. Intersections are indicative of apparent thickness and not true thickness; note that apparent thickness is greater than true thickness.

The drilling method for the holes in Table 1 is reverse circulation (RC). Each drill hole was geologically logged before being sampled at one-meter intervals. Sample analysis was undertaken by UIS Analytical Services, a certified independent laboratory, using a peroxide fusion; ICP-OES analysis was utilised for major and minor elements and ICP-MS was utilised for the trace elements.

About AfriTin Mining Limited

Notes to Editors

AfriTin Mining Limited is a London-listed technology metals mining company with a vision to create a portfolio of globally significant, conflict-free, producing and exploration assets. The Company's flagship asset is the Uis Tin Mine in Namibia, formerly the world's largest hard-rock open cast tin mine.

AfriTin is managed by an experienced board of directors and management team with a current strategy to ramp-up production at the Uis Mine in Namibia to more than 10,000 tonnes of tin concentrate and 350,000 tonnes of lithium concentrate in a Phase 2 expansion, having reached Phase 1 commercial production in 2020. The Company strives to capitalise on the solid supply/demand fundamentals of tin and lithium by developing a critical mass of resource inventory, achieving production in the near term and further scaling production by consolidating assets in Africa.
