Tertiary Minerals to fast-track the Mushima North silver-copper project in Zambia
Tertiary Minerals PLC said it plans to fast-track its Mushima North silver-copper project in Zambia, with drilling due to start shortly as it targets a maiden JORC-compliant Mineral Resource Estimate before the end of 2026.
The AIM-listed explorer recently reported a JORC-compliant Exploration Target for the Target A1 silver oxide discovery of between 15Mt and 30Mt at an average grade of 40-60 grams per tonne silver equivalent, representing up to 58Moz of silver equivalent.
Tertiary said the upcoming programme will focus primarily on the infill drilling needed to support the resource estimate, while technical studies, including metallurgical testwork, will run alongside it. Field activities are expected to begin in mid-May, with expansion drilling at Target A1 and initial drilling at nearby targets also under review.
Managing director Richard Belcher said the company has “a clear pathway for value creation” at Mushima North within “a well-constrained budget and time-frame”.
Elsewhere in Zambia, KoBold Metals continues to review drilling data from the Konkola West project after electing to move into the second stage of its earn-in agreement, while First Quantum has extended its due diligence period at the Mukai project by 12 months to August 2027. Tertiary is also planning initial drilling at Mupala and follow-up drilling at Jacks.
