Uis Exploration Drilling Update
AfriTin Mining Limited (AIM: ATM), a mining company with a portfolio of near production tin assets in Namibia and South Africa, with its flagship asset, the Uis Tin Mine ("Uis") in Namibia, is pleased to provide an update on its operations at the Uis mine.
Highlights
▪ Receipt of the second batch of assay results (five holes) from the resource validation drilling;
▪ Significant intersections include;
o 30.32m @ 0.20% Sn and 91ppm Ta in drill hole V1V2008
o 109.32m @ 0.17% Sn and 77ppm Ta in drill hole V1V2010
o 53.83m @ 0.16% Sn and 73ppm Ta in drill hole V1V20011
In Q4 2018, AfriTin initiated an exploration drilling programme aimed at validating the historic information disclosed by SRK in 1985, for ISCOR, for the V1 and V2 pegmatites. The programme was designed to support the declaration of a maiden, JORC (2012)-compliant, Mineral Resource estimate on the V1 and V2 pegmatites at the Uis Project.
The completion of the validation drilling and initial results of the first five holes were announced on 20 May 2019. The results reported here represent the following five drill holes with subsequent results expected in the near future. The analytical results indicate a continuity of the pegmatite bodies indicated in the previous five holes. The intersections indicate an increase in the thickness of the pegmatites with depth, a trend that is also reflected in the historic drill programme.
In areas where the units are separated into upper, middle and lower the drill hole intercepted a xenolith of country rock which separates the pegmatite body. Sample analysis was undertaken by UIS Analytical Services. The major and minor elements were analysed by ICP-OES and the trace elements were analysed by ICP-MS.

Hole ID | Dip Angle (Degrees) | Pegmatite Unit | From (m) | To (m) | Width (m) | Grade Sn (%) | Grade Ta (ppm) | Grade Li2O (%) |
V1V2007 | Vertical | V2 | 56.46 | 77.07 | 20.61 | 0.11 | 226 | 0.48 |

V1V2010 | Vertical | V2* | 51.26 | 160.58 | 109.32 | 0.17 | 77 | 0.97 |
V1V2011 | Vertical | V2 | 0.78 | 54.61 | 53.83 | 0.16 | 73 | 0.48 |
V1 | 58.51 | 70.03 | 11.52 | 0.23 | 40 | 0.50 |
* The V1 and V2 ore bodies have combined into a single unit
Results received thus far from the current campaign are considered comparable, subject to additional validation work, to those reported by SRK (1985), both in terms of geological validation of the current geological model, and in terms of tin (Sn) grade, with SRK (1985) reporting an average grade of 0.14 % Sn for the V1 and V2 pegmatites.
Anthony Viljoen, CEO of AfriTin Mining Limited commented:
"I am pleased to provide a further update on the confirmatory drilling programme. Of particular interest is a 109m intersection of mineralised pegmatite starting at 51m, indicating the presence of a voluminous ore body extension at depth. While these drilling results are subject to a resource modelling and independent validation process, we are encouraged by these results which remain comparable to the historical data of 1985."
Competent Person Statement:
The technical data in this announcement has been reviewed by Dr Brendan Clarke of CSA Global, who provides geological consulting services to AfriTin. Dr Clarke is Manager - Africa for CSA Global and has 20 years of industry related exploration and mineral project development experience and is a Competent Person for the reporting of Exploration results. He has reviewed both the technical disclosures in this release as well as the quality assurance protocols and results for the assay campaign. Dr Clarke is satisfied that the results of the QAQC on the assay results released to date are sufficient to support the planned estimation of Mineral Resources.
