AZTEC MINERALS STRENGTHENS TECHNICAL MANAGEMENT TEAM

Aztec Minerals Corp. has strengthened its technical management team with the appointment of Curtis Ferron, PGeo, MSc, as vice-president, technical services, and the promotion of Ivan Valencia to exploration manager. Both appointments are effective Nov. 1, 2026.

In his new role, Mr. Ferron will lead the company's mineral resource estimation, economic studies and phase 2 drill program design at the Tombstone project in Arizona as well as technical oversight of the Cervantes project in Sonora, Mexico. He will also serve as the company's qualified person under National Instrument 43-101 for the purposes of its technical disclosure, effective Nov. 1, 2026. Mr. Valencia will report to Mr. Ferron on technical matters and will be responsible for the planning and execution of exploration programs at both projects.

Simon Dyakowski, president and chief executive officer of Aztec, commented: "These appointments come at an important time for Aztec as we advance toward the maiden mineral resource estimate at Tombstone and plan our next phase of drilling. Curtis has worked closely with the company for over a year and brings deep experience in resource estimation, geological modelling and technical reporting, which is exactly the skill set we need as Tombstone moves from discovery toward development. Ivan has been central to our exploration success at Tombstone and Cervantes since 2018, and his promotion recognizes the leadership he has shown on the ground. Together they give Aztec a strong, experienced technical team for the next stage of the company's growth."
