Andrada Mining Ltd (AIM:ATM, OTC:AFTTF) said all holes at its inaugural drilling programme at the historical Brandberg West minion on its EPL5445 exploration licence intersected metal.
In the first of ten samples from twenty holes drilled, tin, tungsten and copper were all recorded with the best grades 4.47% tin, 2.65% tungsten and 3.85% copper.
Anthony Viljoen, chief executive, commented: "The Brandberg West project's initial drilling results are highly encouraging featuring significant high-grade intersections of tin, tungsten and copper.
"These intersections, with grades of up to 4% for tin, over 2% for tungsten and typically 0.5% - 2% for copper, underscore the licence's commercial potential.
"Notably, Brandberg West expands Andrada's portfolio of critical metals to include tungsten and copper."
The Brandberg West project is situated within exploration license EPL 5445 in the Erongo region of Namibia, approximately 100km from the Uis Tin Mine, Andrada Mining's flagship asset.
Gold Fields owned and operated the historical open pit mine at Brandberg West until operations ceased in the 1980s when the tin price collapsed.
