TERTIARY MINERALS

Tertiary Minerals has started an approximately 1,000-metre reverse-circulation drilling program on Target A1 of the Mushima North project in Zambia to follow up on promising results from mid‑2025. Earlier holes returned, among other intercepts, 58 metres at 49 g/t silver, 0.26% copper and 0.16% zinc from 8 metres depth. The holes will test lateral extensions, continuity between drill spacings and depth extensions down to 150 metres with the aim of quickly defining an exploration target and delivering an initial mineral resource estimate within 12 months. The program is expected to be completed in about two weeks; samples will be screened onsite by X‑ray fluorescence and selected intervals sent to a laboratory for analysis. » More on de.investing.com

Tertiary Minerals reports at Mushima North a drill intersection of 58 m with 49 g/t silver and 0.26% copper and a 9 m interval with 124 g/t silver and 0.73% copper. New drilling extends the mineralisation in the Target A1 prospect area by about 100 m to the north; the near-surface zone now covers roughly 450 x 400 m and remains open to the north, south and at depth. The project is 90% held by Copernicus Minerals and is being operated under a technical cooperation with First Quantum Minerals. » More on de.investing.com

Tertiary Minerals plc has begun drilling at the polymetallic exploration target A1 at the Mushima North project in Zambia. The program includes up to 1,500 meters of drilling to investigate silver, copper, and zinc mineralization, following significant results from previous drilling. The work is being carried out in collaboration with local partners and First Quantum Minerals Limited. » More on de.investing.com
