INTEGRA PUBLISHES 5TH ANNUAL SUSTAINABILITY REPORT

Integra Resources Corp. has published its fifth annual sustainability report, outlining Integra's strong performance over a transitional year as the company moved into production with the acquisition of the Florida Canyon mine in northern Nevada. The report aligns with the international financial reporting standards (IFRS) sustainability accounting standards board (SASB) metals and mining standard, and covers Integra's activities and performance from Jan. 1, 2024, to Dec. 31, 2024. As disclosed, certain metrics within the report include data from Florida Canyon exclusively for the two-month period of November and December, 2024, outlining performance while under Integra ownership.

Environmental, social and governance (ESG) highlights

Environmental:

• Maintained zero reportable spills across the company's development projects and at operating sites since Integra ownership;
• Sustained water management performance across the company's operations, with no breaches in water discharge permits and strict adherence to environmental standards;
• Expanded the company's memorandum of understanding (MOU) with Trout Unlimited to include additional conservation efforts in proximity to Integra's operations in northern Nevada.

Social:

• Contributed over $90,000 (U.S.) to local communities through donations, sponsorships and in-kind support, supporting over 22,500 people through community programs and strategic investments;
• Connected with more than 12,000 individuals through meaningful outreach and stakeholder engagement efforts;
• Exemplary health and safety performance at Florida Canyon mine in 2024, underlined by nine team members receiving safety awards from the Nevada Mining Association;
• Achieved zero lost-time injuries across all assets, with a year-over-year improvement in the total incident frequency rate.

Governance:

• Successfully completed the acquisition of Florida Canyon, strengthening operational capacity and supporting strategic growth;
• 30 per cent of corporate objectives are ESG-linked (environmental, social and governance) and 100 per cent of these metrics were fulfilled.

George Salamis, president, chief executive officer and director of Integra, commented: "For years, Integra has used a development strategy hinged upon the idea that strong environmental, social and governance principles would underpin how we design, permit and build our future operations. Now, as the operators of Florida Canyon, the measure lies in our ability to apply those principles as we deploy capital to support consistent production at Florida Canyon, as well as drive the company's broader growth strategy. Integra continues to lead with transparency, with respect for local communities and tribal nations, and with the recognition that exceptional environmental, social and governance performance are fundamental drivers that create lasting value for all stakeholders."

The 2024 sustainability report is available on Integra's website.
