Tertiary Minerals shares soar on 'best hole yet' at Mushima North

Tertiary Minerals PLC shares surged 69% following the announcement of its highest-grade silver and copper intersection to date at the Mushima North project in Zambia. The latest drill hole at Target A1 returned 58 meters at 72 g/t silver equivalent, including a high-grade section of 9 meters at 185 g/t silver equivalent and 2.40% copper equivalent, with mineralization remaining open in multiple directions and at depth, supporting a bulk tonnage, open pit exploration model.

Analysis

Tertiary Minerals (AIM:TYM) shares surged 69% to 0.071p following the release of highly positive drilling results from its Mushima North project in Zambia. The catalyst was the 'best hole yet' at Target A1, which yielded a significant intersection of 58 meters at 72 grams per tonne (g/t) silver equivalent. This included a high-grade interval of 9 meters at 185 g/t silver equivalent and 2.40% copper equivalent from a relatively shallow 57 meters. The significance of this finding is twofold: it materially de-risks the project by confirming high-grade mineralization, and it supports the company's exploration model for a bulk tonnage, open-pit operation. Critically, management stated the deposit, which currently spans a 450m by 400m footprint, remains open to the north and at depth, suggesting substantial upside potential for resource expansion in future drilling campaigns. The market's strong reaction indicates investors perceive this discovery as a pivotal value-creation event for the exploration company.

Key Decisions for Investors

• The high-grade results and the fact that the deposit remains open in multiple directions present a compelling case for resource upside, positioning the stock for investors with a high tolerance for exploration-stage risk.
• Given the sharp 69% single-day share price increase, investors should be cautious of potential short-term volatility and profit-taking, and may consider waiting for a consolidation period before building a position.
• The primary focus for investors should be on upcoming news flow related to follow-up drilling, as the results will be critical in determining the ultimate scale and economic viability of the Mushima North discovery.
