Tertiary Minerals to fast-track Zambia silver-copper project

Tertiary Minerals (primary instrument: XAGUSD) said it will fast‑track its Mushima North silver‑copper project in Zambia, starting field activities and drilling in mid‑May and targeting a maiden JORC‑compliant Mineral Resource Estimate by end‑2026. The company earlier reported a JORC Exploration Target at Target A1 of 15–30Mt at 40–60 g/t silver equivalent (up to ~58Moz Ag‑eq). The near‑term programme will prioritise infill drilling to support the resource estimate with metallurgical testwork and technical studies running alongside. The update and timetable could be a positive catalyst for Tertiary’s shares by de‑risking the project and creating a clearer value pathway; it also highlights continued third‑party interest in Zambian targets as KoBold and First Quantum progress separate agreements and due diligence.
