The Ontario Prospectors Association (OPA) is undergoing a bold revitalization. We are rebuilding an organization that reflects the future of mineral exploration in Ontario—grounded in integrity, guided by good governance, and powered by the diverse voices of its members. OPA advocates for the prospectors, geoscientists, explorers, and communities who drive discovery in Ontario.
Our mission is clear: to make Ontario the best place in the world to explore.
As we reimagine the OPA, your participation matters. We are growing our Board, launching active committees, and advancing a strong lobbying effort to support land access, Indigenous partnerships, education, and the next generation of explorers.
Join us. Be part of the movement to shape policy, open doors, and secure a strong future for Ontario’s exploration sector.
