Management Commentary

Réjean Provost, Vice-President Business Development at Windfall Geotek, commented:

“Windfall Geotek has been active in the Latin American market, and we believe that with a strong local presence these are strategic markets for the expansion of our AI/ML-driven mineral exploration technology. The signing of representation agreements with experienced local agencies supports our international growth strategy and demonstrates the ability of our technology to be deployed across mining jurisdictions worldwide.

“Argentina, Chile and Peru are among the world’s leading mining jurisdictions, particularly for copper, with extensive geological and geophysical datasets ideally suited to Windfall Geotek’s AI/ML targeting approach. By combining our proven technology with Mr. Pernas’ extensive network and knowledge of the Latin American mining sector, we believe we can accelerate market penetration and generate meaningful commercial opportunities. This process is already underway, with several prospective opportunities and industry introductions identified.

“Together with our recent announcement of representation in Japan and Australia, these agreements support Windfall Geotek’s strategy of expanding internationally through knowledgeable local partners while maintaining a highly scalable business model. Our objective is to convert more than two decades of AI/ML development and successful mineral targeting into a growing pipeline of commercial projects, strategic partnerships and discovery opportunities for Windfall Geotek and its shareholders.”
