Drilling begins at Tertiary Minerals’ Mushima North project in Zambia

LUSAKA - Tertiary Minerals plc (AIM:TYM) commenced drilling at its Target (NYSE:TGT) A1 polymetallic prospect within the Mushima North Project in Zambia, the company announced Monday.

The drilling program includes up to 1,500 meters of Air Core and Reverse Circulation drilling to test continuations of previously identified silver-copper-zinc mineralization. The program started on July 18 and is expected to take 2-3 weeks to complete.

Previous drilling at Target A1 in late 2024 yielded significant results, including 57 meters at 25 g/t silver, 0.20% copper, and 0.15% zinc from 14 meters downhole, and 65 meters at 23 g/t silver, 0.14% copper, and 0.27% zinc from 9 meters downhole.

The current drilling aims to test the silver and zinc soil anomaly over approximately 1.6 kilometers of strike length and up to 300 meters width, while also exploring depth extensions of mineralization to 150 meters in key areas.

Target A1 is located 28 kilometers east of the historic Kalengwa copper-silver mine, which is currently under redevelopment and expected to produce 15,000 tonnes of copper annually.

The Mushima North Project is held through Copernicus Minerals Limited, which is 90% owned by Tertiary Minerals (Zambia) Limited and 10% by local partner Mwashia Resources Limited. The project operates under a technical cooperation agreement with First Quantum Minerals (OTC:FQVLF) Limited.

Samples from the drilling program will initially be analyzed on-site using a portable X-Ray Fluorescence analyzer for copper and zinc, with selected mineralized intervals being submitted to a certified laboratory for comprehensive analysis of silver, copper, zinc, bismuth, antimony, and gallium.
