Tertiary Minerals plc ("Tertiary" or "the Company")

PROJECT FOCUS - KONKOLA WEST, ZAMBIA

The Company's Konkola West Copper Project in Zambia has been brought into sharp focus by the recent $150 million investment in the adjacent Mingomba Copper Deposit (Lubambe Extension Project) by KoBold Metals, whose shareholders include Breakthrough Energy Ventures, a climate and technology fund founded by Microsoft's Bill Gates and backed by Amazon's Jeff Bezos, and Virgin's Sir Richard Branson, and mining giant BHP (announced at the Biden Administration's 2022 African Leader's Summit).

The Company is therefore releasing a separate "Project Focus" presentation which can now be found on the Company's website at https://www.tertiaryminerals.com/presentations

Konkola West, one of five copper projects in Zambia where Tertiary has an interest, is targeting deep down-dip extensions of the contiguous Musoshi-Lubambe-Mingomba-Konkola copper deposits which host the Musoshi Mine in the Democratic Republic of the Congo and the Lubambe Mine and Konkola mines and concentrators in Zambia. Together these deposits define a continuous zone of mineralisation over 15km long with a pre-mining endowment of over 775 million tons grading 2-3% copper. Konkola West is located approximately 2,000m southwest of the Mingomba deposit which currently has a resource of 250 million tons at 3.8% copper.

The Company's interests in Zambia also include the Jacks Copper Project where the Company completed soil sampling and drilling in 2022 and the Mukai and Mushima North project areas where the Company is working with First Quantum Minerals to evaluate historical data and generate new exploration targets for evaluation in 2023.

The "Project Focus" now released for Konkola West Project is one of a number of such presentations planned for the Company's key exploration projects over the coming weeks.
