Adriatic Metals said that Mike Norris, the miner's chief financial officer, has handed in his notice to pursue other opportunities.
Michael Horner, head of business development, has been appointed interim CFO.
Horner has ten years experience in the mining industry across M&A, capital markets, finance and operations, said the statement.
Paul Cronin, Adriatic’s chief executive, added: "On behalf of the board I would like to extend my gratitude to Mike Norris for his contributions to Adriatic over the past two years and wish him well for his future endeavours.
Mike joined the team at the commencement of the construction of the Vares Silver Operation, and through solid fiscal discipline, successfully navigated that pivotal period to bring the project to completion, largely on time and on budget, despite substantial macro headwinds.
“Michael [Horner] brings considerable experience in corporate finance and will lead Adriatic through its next phase as a producer, working to lower our cost of capital and execute on new growth opportunities.
“As the company transitions to mining owner-operator over the coming months, the management team will focus on increasing underground development, enhancing operational efficiencies, and bringing the operations to nameplate production in Q4 2024.”
