Integra Resources Corp. (TSXV: ITR; NYSE American: ITRG), a growing precious metals producer operating in the Great Basin of the Western United States, released its fifth annual sustainability report on October 16, 2025. The Vancouver-based company focuses on demonstrating profitability and operational excellence at Florida Canyon Mine in Nevada while advancing its flagship development projects: the DeLamar Project in southwestern Idaho and the Nevada North Project in western Nevada. The 2024 report covers a transformational period as Integra transitioned from pure development to production operations, providing investors with critical insights into the company's operational discipline and ESG performance during this strategic evolution.

For investors evaluating Integra Resources, this sustainability report offers tangible evidence of the company's ability to execute on ESG commitments while managing the complexities of mine acquisition and operational integration. The report's alignment with International Financial Reporting Standards Sustainability Accounting Standards Board Metals and Mining Standard provides standardized metrics that enable meaningful comparison with industry peers and supports informed investment decisions.

Strategic Transition to Production Operations

The 2024 reporting period represents a watershed moment for Integra Resources as the company completed its acquisition of Florida Canyon Mine in northern Nevada. This transaction fundamentally altered the company's operational profile, transforming it from a pure development company into an active producer with immediate cash flow generation capabilities.

The sustainability report covers activities and performance from January 1, 2024 to December 31, 2024, with certain metrics including data from Florida Canyon exclusively for the November-December 2024 period following completion of the acquisition. This two-month operational window under Integra ownership provides investors with an initial baseline for evaluating management's ability to maintain and improve existing operations while integrating new assets into the corporate portfolio.

President, CEO and Director George Salamis emphasized the strategic importance of this transition:

"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."

The Florida Canyon acquisition strengthens Integra's operational capacity while providing a platform for near-term production growth. For investors, the successful integration of this producing asset demonstrates management's capability to execute on strategic M&A while maintaining focus on ESG performance metrics that increasingly influence investment decisions and access to capital.

Safety Performance & Workforce Development

Integra's 2024 safety performance provides concrete evidence of operational discipline during a period of significant organizational change. The company achieved zero lost-time injuries across all assets, a critical metric that reflects both strong safety culture and effective management systems. Year-over-year improvement in total incident frequency rates further demonstrates the company's commitment to continuous improvement in workplace safety.

The Florida Canyon operation delivered particularly strong results, with nine team members receiving safety awards from the Nevada Mining Association. This external recognition from an established industry body validates Integra's safety protocols and provides third-party confirmation of operational excellence. For investors evaluating management quality and operational risk, these safety metrics offer quantifiable evidence of effective leadership and systematic risk management.

Zero lost-time injuries represent more than just a positive ESG metric they directly impact operational continuity, insurance costs, regulatory relationships, and the company's ability to attract and retain skilled workers in competitive labor markets. Mining operations that maintain strong safety records typically experience lower employee turnover, reduced training costs, and improved productivity through experienced workforce retention.

Environmental Stewardship & Water Management

Integra maintained zero reportable spills across development projects and operating sites since assuming ownership of Florida Canyon. This performance metric is particularly significant given the operational transition period when integration challenges could potentially compromise environmental controls. The absence of reportable spills demonstrates that existing environmental management systems remained effective throughout the acquisition process.

Water management performance remained consistently strong throughout 2024, with no breaches in water discharge permits and strict adherence to environmental standards across all operations. Water management represents one of the most critical environmental challenges for mining operations in the Great Basin region, where water scarcity and competing demands from agriculture, municipal users, and environmental protection create complex regulatory environments.

The company expanded its Memorandum of Understanding with Trout Unlimited to include additional conservation efforts in proximity to Integra's operations in northern Nevada. This partnership demonstrates proactive stakeholder engagement that extends beyond regulatory compliance to address broader ecosystem health concerns. For investors, such partnerships can reduce operational risk by building social license to operate and creating collaborative relationships with conservation organizations that might otherwise oppose mining activities.

Environmental performance metrics directly influence regulatory relationships, permitting timelines, and community support all factors that materially impact project development schedules and capital efficiency. Integra's track record of zero reportable spills and zero water permit breaches positions the company favorably for future permitting activities at its development projects.

Community Investment & Stakeholder Engagement

Integra contributed over $90,000 to local communities through donations, sponsorships, and in-kind support during 2024. These investments supported over 22,500 people through community programs and strategic investments, demonstrating meaningful impact relative to the company's size and operational footprint. The company connected with more than 12,000 individuals through outreach and stakeholder engagement efforts, reflecting systematic attention to relationship-building with communities surrounding its operations and development projects.

Salamis articulated the company's stakeholder-focused approach:

"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."

Community investment and stakeholder engagement represent strategic investments rather than discretionary charitable giving. Mining projects require sustained community support throughout multi-decade operational lifecycles, and early investment in community relationships can significantly reduce operational risk and accelerate permitting processes. For development-stage projects like DeLamar and Nevada North, community support will be essential for obtaining final permits and maintaining social license during construction and ramp-up periods.

The company's explicit recognition of relationships with Tribal Nations reflects awareness of the legal and cultural importance of indigenous rights in areas where Integra operates. Effective tribal consultation processes have become essential for project development in the western United States, and companies that build respectful relationships early in project lifecycles typically experience fewer delays and lower overall project risk.

Governance Structure & ESG Integration

Integra's governance framework integrates ESG considerations directly into corporate objective setting and performance evaluation. Thirty percent of corporate objectives are ESG-linked, and the company fulfilled 100% of these metrics during 2024. This integration ensures that ESG performance receives equivalent management attention and resource allocation as traditional financial and operational metrics.

The successful completion of the Florida Canyon acquisition demonstrates governance capability during complex transactions that require careful due diligence, financing coordination, and stakeholder management. For investors, transaction execution capability is a key indicator of management quality, particularly for companies pursuing growth through strategic M&A alongside organic project development.

The company's decision to align its sustainability reporting with the IFRS Sustainability Accounting Standards Board Metals and Mining Standard provides investors with standardized metrics that facilitate peer comparison and portfolio analysis. As ESG reporting requirements continue to evolve globally, early adoption of internationally recognized standards positions Integra favorably for emerging regulatory requirements and institutional investor expectations.

Development Pipeline & Growth Strategy

While the 2024 sustainability report focuses primarily on operational performance at Florida Canyon and ongoing environmental and community work at development projects, Integra's growth strategy encompasses significant development optionality through the DeLamar Project in Idaho and Nevada North Project. These past-producing properties represent potential future production growth that would diversify the company's operational base and expand production capacity.

The company's emphasis on environmental and social performance during the development phase positions these projects favorably for permitting advancement. Development projects that establish strong community relationships, demonstrate environmental stewardship, and maintain transparent stakeholder engagement typically experience more efficient permitting processes and lower execution risk during construction.

Integra's integrated approach combining producing operations at Florida Canyon with advanced-stage development projects provides investors with near-term cash flow alongside medium-term production growth optionality. This balanced portfolio structure reduces risk compared to pure development companies while offering greater growth potential than single-asset producers.

Financial Implications & Investment Considerations

Strong ESG performance increasingly influences mining companies' access to capital, insurance costs, regulatory relationships, and ability to attract partners for project development. Integra's demonstrated track record across environmental, social, and governance metrics should support favorable terms for future financing activities and potentially attract strategic partners for development projects.

The company's capital allocation strategy emphasizes three priorities: demonstrating profitability and operational excellence at Florida Canyon; advancing flagship development projects; and pursuing strategic M&A opportunities. This disciplined approach to capital deployment, combined with strong ESG performance, positions Integra to create shareholder value through multiple pathways while managing downside risk through operational diversification.

For investors evaluating Integra Resources, the sustainability report provides evidence that management can maintain ESG commitments during operational transition periods and successfully integrate acquired assets while preserving environmental and safety performance. The company's zero lost-time injury record, zero reportable spills, and 100% achievement of ESG-linked objectives demonstrate operational discipline that should translate into efficient capital deployment and reduced operational risk.

Conclusion

Integra Resources' fifth annual sustainability report documents strong ESG performance during a transformational year that saw the company complete its transition to production operations through the Florida Canyon acquisition. The achievement of zero lost-time injuries, zero reportable spills, 100% fulfillment of ESG-linked objectives, and meaningful community investment demonstrates that management successfully navigated organizational complexity while maintaining operational discipline.

For investors evaluating Integra Resources, the company presents an investment opportunity that combines near-term production and cash flow from Florida Canyon with development optionality through the DeLamar and Nevada North projects. The sustainability report provides tangible evidence that management can execute on operational commitments while building the stakeholder relationships and regulatory track record necessary for future growth. As ESG considerations increasingly influence capital allocation decisions and regulatory requirements in the mining sector, Integra's demonstrated performance across environmental, social, and governance metrics positions the company favorably relative to development-stage peers and supports the investment case for long-term value creation.
