Tertiary Minerals Begins New Drilling Campaign at Zambia’s Mushima North Project After High-Grade Gold and Copper Hits
AIM-listed Tertiary Minerals has commenced a 1,500-metre air core and reverse circulation drilling programme at its Mushima North Project in Zambia, focusing on Target A1—a highly promising zone identified in previous drilling.
The new drill campaign is designed to test both strike and downdip extensions of mineralisation discovered during a successful drilling programme in late 2024. That campaign returned standout intersections, including:
57 metres grading 25 g/t gold, 0.20% copper, and 0.15% zinc from 14 m downhole
65 metres grading 23 g/t gold, 0.14% copper, and 0.27% zinc from 69 m downhole
Target A1 is located 28 km east of the historic Kalengwa copper-silver mine, which is currently undergoing redevelopment.
Tertiary Managing Director Richard Belcher noted that the initial 1,274-metre drill programme revealed near-surface polymetallic mineralisation extending over a 350-metre width, with drill intervals reaching up to 67 metres.
h3Many holes, he added, ended in mineralisation, indicating strong continuation potential.
The current programme aims to:
Further define the surface footprint of silver and zinc anomalies, which stretch over a 1.6 km strike length and are approximately 300 metres wide
Investigate the downdip potential of the mineralisation to depths of up to 150 metres
Tertiary Minerals owns 90% of Copernicus Minerals, which holds 100% ownership of the Mushima North Project.
