INTEGRA ENTERS INTO EQUITY AGREEMENT WITH THE SHOSHONE-PAIUTE TRIBES

• Integra Resources Corp. entered into an equity agreement with the Shoshone-Paiute Tribes on May 13, 2026.
• The Company granted 517,103 common shares valued at US$1,500,000 to the Tribe.
• Share price used for valuation was C$3.97 per share (closing price on TSX Venture Exchange).
• Purpose is to foster a long-term partnership and collaborative framework for the DeLamar Project development.
• Scope includes participation in baseline data collection, tribal monitoring, and mine plan co-development.
• Closing conditions include approval from the NYSE American.
• This follows previous relationship agreements signed in August 2025 regarding the DeLamar project.

• Financial Impact: The equity grant represents a nominal value of US$1.5 million against a market capitalization of approximately US$788 million, representing less than 0.2% dilution and negligible financial impact on the balance sheet.
• Strategic Impact: Confirms execution of the social license strategy previously announced in August 2025 (Relationship Agreement) and December 2025 (MPO acceptance).
• Market Expectations: The market was aware of the tribal partnership framework; this is a specific implementation step rather than new strategic direction.
• Stock Price Context: The stock has corrected significantly from January highs ($6.38) to current levels ($3.91); this news provides minor support but does not alter the fundamental valuation derived from the Feasibility Study released in February 2026.
• Rating Justification: Classified as Routine - Positive because it is an expected follow-up to established agreements and lacks new financial or operational catalysts that would materially shift investor expectations beyond current pricing.

• Primary Operating Asset: Florida Canyon Mine in Nevada, USA (Producing Heap Leach Gold Mine).
• Flagship Development Project: DeLamar Gold-Silver Heap Leach Project in Idaho, USA.
• Secondary Project: Nevada North Project (Wildcat & Mountain View deposits) targeting Pre-Feasibility Study completion in H2 2027.
• Strategy: Build a growing precious-metals producer focused on the Great Basin of the USA by leveraging cash-flowing production at Florida Canyon to fund growth projects.
• Production Profile: Florida Canyon produced 12,635 oz gold in Q1 2026; Full-year guidance for 2026 is 70,000–75,000 oz.
• DeLamar Economics: Feasibility Study (Feb 2026) projects 1.1M oz AuEq over 10 years with AISC of $1,480/oz and NPV5% of ~$774 million at base case prices.
