Tertiary Minerals plc has revealed plans to commence deeper drilling at its Mushima North project in Zambia. The focus will be on testing the extension of mineralization beneath the Discovery Zone, potentially uncovering a higher-grade primary sulphide deposit.

The company has begun preparations for its inaugural diamond drilling program at the site. This initiative will involve up to four holes, totaling 1,000 meters. The drilling will probe mineralization to a depth of approximately 200 meters, extending beyond the 125 meters achieved during the recent Phase 4 drilling.

Richard Belcher, managing director of Tertiary Minerals, expressed enthusiasm about the upcoming drilling season:

“We are very excited to be back drilling again this field season at the Discovery Zone where we have made great progress and have already completed over 3,600m of Reverse Circulation drilling to support our Mineral Resource Estimation work.”

The Discovery Zone boasts a previously reported Exploration Target of 15–30 million tonnes, grading 40–60 grams per tonne silver equivalent. Recent drilling identified a higher-grade zone with a surface footprint of up to 400 meters by 150 meters, with mineralization remaining open at depth.

The forthcoming four-week program will not only test for the continuation of mineralization below the Discovery Zone but also provide core samples for further metallurgical and technical testing. Initial laboratory results from these samples are anticipated six to eight weeks after submission.

As the company awaits the final assays from Phase 4 drilling and initial metallurgical testwork results, which are expected imminently, Belcher remarked:

“With the last of the laboratory results for the recent Phase 4 drilling due imminently, along with the initial metallurgical testwork results, we are then positioned for a very strong finish to this year’s Zambian field season.”

Tertiary Minerals aims to establish a Mineral Resource Estimate by the end of 2026, marking a significant milestone for the Mushima North project.
