VANCOUVER, BC, May 13, 2026 /CNW/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV:ITR) (NYSE:ITRG) and the Shoshone-Paiute Tribes (the "Shoshone-Paiute") are pleased to announce they have entered into an agreement pursuant to which Integra will grant 517,103 common shares of the Company (the "Common Shares") to the Shoshone-Paiute with an aggregate value of US$1,500,000 (the "Equity Grant"). The Common Shares are priced at C$3.97, which reflects the closing price of the Common Shares on the TSX Venture Exchange immediately prior to execution of the agreement.

Today's announcement reflects the significant work undertaken by Integra and the Shoshone-Paiute to collaboratively design and implement processes and initiatives to address their respective interests in respect of the DeLamar Project  ("DeLamar" or the "Project"), including significant work undertaken with respect to participation in baseline data collection, tribal monitoring, and mine plan co-development. The Equity Grant is a tangible step toward the parties building further consensus regarding the Project and supports the Shoshone-Paiute to participate as a long-term partner with a direct interest in value creation associated with the Project. The Equity Grant represents a further step in an evolving relationship between Integra and the Shoshone-Paiute, grounded in mutual respect, shared outcomes, and alignment on how the DeLamar Project is advanced.

Completion of the Equity Grant is subject to customary closing conditions, including the approval of the NYSE American. 

George Salamis, President and CEO of Integra Resources, commented: "Integra views this as a further step in building a long-term partnership with the Shoshone-Paiute in relation to the DeLamar Project. The work we have done together to date has helped shape a Project that is better understood, more predictable, and better positioned to earn support locally and across the region by all stakeholders. Our focus is on advancing DeLamar responsibly and aggressively - creating jobs, supporting the regional economy, and building a Project with a positive legacy that communities can stand behind over the long term."

Chairman Brian Mason of the Shoshone-Paiute commented: "Our Nation takes a generational view in evaluating opportunities to ensure they align with Shoshone-Paiute values, protect our cultural resources, and support lasting benefits for our people. Equity ownership reflects the progress we have made in building a relationship with Integra based on respect and transparency. This allows us to participate with projects where there is alignment, furthering our goals for economic independence and diversification and a healthy future for our Nation, while maintaining our sovereignty in how projects move forward."

The DeLamar Project, developed with demonstrated dedication to early engagement and alignment of broad interests, has evolved with a maintained focus on efficient and predictable advancement through permitting, so that it may contribute to regional economic growth, and create long-term opportunities for local communities. As the DeLamar Project continues to advance, the Company remains focused on transparency, responsible development, and building broad-based support across all stakeholders. The Equity Grant announced today is intended to support long-term economic opportunities for the Shoshone-Paiute Tribes while reinforcing a collaborative framework for engagement specific to the DeLamar Project.
