Mr. Fausto Di Trapani reports

TIERNAN CONTINUES TO STRENGTHEN EXECUTIVE TEAM, HIRES PASCAL LAMBERT-PARADIS AS CHIEF FINANCIAL OFFICER

Tiernan Gold Corp. has appointed Pascal Lambert-Paradis as chief financial officer, effective August 1, 2026.

In this role, Mr. Lambert-Paradis will lead all financial planning, reporting, treasury and internal control functions for the company and will be a key member of the leadership team advancing Tiernan's flagship Volcan gold project in Chile's Maricunga gold belt through engineering, environmental impact assessment, preliminary feasibility study (PFS) and into future execution phases.

"Pascal is a known quantity to me -- we worked together at MAG Silver, where he built the finance function and graduated reporting from late-stage development to operations. He has run site-level finance, corporate reporting and financial planning and analysis at multibillion-dollar producers," said Fausto Di Trapani, president and chief executive officer. "That range matters for a company of our size, where the CFO touches everything from project cost controls to external reporting to investor disclosure. He's trilingual, he knows Chile, and he can step in without a learning curve. As Volcan advances through engineering and toward a PFS, Pascal will build the financial infrastructure our company needs to scale into future execution and growth."

Claudia Tornquist has stepped down as interim chief financial officer, effective Aug. 1, 2026. The company thanks Ms. Tornquist for her service during the RTO (reverse takeover) transaction and transition period.
