• Following constructive dialogue, Tinka and Pillao have agreed to work collaboratively to facilitate the execution of exploration and other technical studies at Colquipucro.
• The agreement has a three-year term, commencing when Tinka initiates exploration activities at Colquipucro. Tinka has also committed to provide opportunities for the community stakeholders, including local employment and potential collaborative investment initiatives.

Dr. Graham Carman, president and chief executive officer of Tinka, stated: "We thank the San Pedro de Pillao community for its confidence in Tinka and for reaching this agreement, which represents an important step in establishing a framework for future exploration and technical work at Colquipucro. We are committed to building constructive, long-term relationships with our local communities, and we look forward to working collaboratively with Pillao as the project advances.

"Meanwhile, work on the previously announced PEA update is progressing well (news release Oct. 15, 2026).
