04:40 AM EDT, 10/08/2026 (MT Newswires) -- Tertiary Minerals (TYM.L) is planning a deeper drilling program at the Target A1 silver-copper-zinc prospect in its Mushima North copper project in Zambia. The diamond drill program of up to 1,000 meters aims to test whether mineralization continues beneath the current holes, targeting higher-grade mineralization and the potential for a primary sulphide deposit, according to a Thursday release. The mineral exploration and development company expects drilling to begin soon after a general meeting scheduled for Oct. 28 and to take four weeks.
