Tertiary Minerals PLC announced encouraging initial drilling outcomes at its Mushima North copper and zinc project in Zambia, confirming the continuation of a higher-grade copper zone across the northern section of Target A1.

Preliminary pXRF analysis revealed significant mineralization, including a 45-metre interval grading 0.41% copper and 0.28% zinc starting at 12 metres depth, highlighted by a 6-metre section with 1.01% copper. Additional intersections recorded 55 metres at 0.32% copper and 0.29% zinc, and 73 metres at 0.29% copper and 0.38% zinc.

Indicative silver readings from the first 12 holes reached up to 214 grams per tonne. Tertiary noted these silver values are semi-quantitative, with all reported intersections measured as downhole widths; true widths are yet to be determined.

Supporting the existing exploration target of 15-30 million tonnes grading 40-60 grams per tonne silver equivalent, infill drilling continues to progress ahead of planned work to define a JORC-compliant mineral resource. To date, 22 holes totaling 2,175 metres have been completed as part of a 4,000-metre drilling programme, with certified laboratory results expected in the coming weeks.

These results reinforce Tertiary Minerals’ confidence in the Mushima North project’s potential and mark a significant step toward advancing the resource evaluation and development plans.
