Ms. DeLazzer most recently served as vice-president, exploration, at Northern Superior Resources Inc., where she led corporate exploration strategy across a large, district-scale land position and oversaw the advancement of a multiasset portfolio within the Chibougamau gold camp. During her tenure, she oversaw multimillion-dollar exploration programs and was instrumental in advancing a camp-scale consolidation strategy, including the acquisition and integration of key properties. She contributed to technical reporting, strategic planning and corporate development initiatives, supporting the company's growth and ultimate acquisition by Iamgold Corp.

Drew Anwyll, PEng, chief executive officer of Mayfair Gold, stated: "We are very pleased to welcome Adree to the Mayfair team. She brings a strong combination of technical expertise and practical experience in advancing large-scale gold systems in the Abitibi greenstone belt.

Adree DeLazzer, vice-president, exploration, of Mayfair Gold, stated: "I am excited to join Mayfair at an important stage in the company's growth. The Fenn-Gib project is a well-defined asset, and the broader land package presents a compelling opportunity to evaluate additional targets along the Destor-Porcupine deformation zone. I look forward to working with the team on the ground to advance exploration programs focused on defining and prioritizing structurally controlled high-grade gold targets across the property."

With Ms. DeLazzer leading the exploration team, she will be working closely with Mr. Metail, who will take on the expanded scope of vice-president, mineral resource management, at Mayfair on the Fenn-Gib project.
