Tiernan Gold Corp. (TSXV : TNGD)

("Tiernan" or the "Company") is pleased to announce the appointment of James Connolly as Executive

Vice President, Projects, effective May 12, 2026.

In this role, Mr. Connolly will lead all engineering and feasibility activities and be a cornerstone in

"With 25 years of hands-

on experience advancing complex, multi-billion dollar gold, lithium, and base-metal projects from

conceptual studies through feasibility, permitting, and execution, James has delivered exactly the

technical and strategic results Volcan requires right now. His track record at Allkem, Vale, and Barrick,

including direct experience in the 'Puna de Atacama' region of Chile and Argentina, will keep our

engineering and EIA on track and on budget, and drive significant value addition through disciplined

project execution and de-risking of Volcan."
