George Salamis, Integra's President & CEO, stated, "We are proud of Integra's substantial first efforts to disclose our practices and performance in ESG in a formal context. We welcome this opportunity to highlight the accomplishments of our team who performed admirably in the midst of a pandemic, putting the health and safety of our employees and our host communities first, all the while continuing to responsibly advance the DeLamar Project in an assertive manner on the exploration and development fronts."

"Our team is excited by the many prospective ideas we are evaluating to design an economically robust, responsible, and resilient future operation," commented Mark Stockton, VP of Corporate Affairs & Sustainability. "Committing to ESG early on has proven itself to reveal many opportunities for our growing Company. This is apparent in the culture we are creating and the support we are experiencing from the community, and also in areas such as the engineering solutions in greenhouse gas emission reduction strategies being evaluated for our upcoming Pre-feasibility Study. We are seeing that the dividends of our ESG program are not only socially and environmentally beneficial, but interestingly some of the most exciting options are potentially very economic as well."
