"With the release of what is now our third annual Sustainability Report, I am extremely pleased to report on the progress that we have made to maintain a commitment to strong sustainability practices, health and safety and community engagement while remaining disciplined in our growth strategy, focused on growing and adding value to our portfolio of exploration stage gold assets in the Americas."

"In our fiscal year 2024 Sustainability Report, we demonstrate that we have strengthened our safety culture through increasing our health and safety training by five-fold compared to when we began reporting, which has contributed to the completion of a safe drill campaign at our São Jorge Project, with no reportable lost time incidents."

In addition, we initiated supplier sustainability screening with the goal to ensure we proactively protect against human rights risks and ensure our material suppliers uphold similar commitments, including to environmental management and health and safety. Through this steadfast focus, we are actively and responsibly advancing a diversified portfolio of resource-stage gold and gold-copper projects in Canada, U.S.A., Brazil, Colombia, and Peru for the benefit of our stakeholders right from our local communities through to our shareholders."
