IsoEnergy (TSX:ISO) operates as a leading, globally diversified uranium company with substantial mineral resources across premier uranium mining jurisdictions. The company's strategic positioning spans near, medium, and long-term production opportunities, providing investors with comprehensive exposure to rising uranium prices through a diversified asset base.

The company's flagship Larocque East project in Canada's Athabasca basin houses the Hurricane deposit which boasts the world's highest-grade indicated uranium mineral resource.

Environmental Performance & Operational Readiness

The timing of this sustainability report coincides with IsoEnergy's advancement toward potential near-term production, indicating management's recognition that ESG considerations have become integral to modern mining operations. The report covers the full year 2024, providing investors with baseline metrics against which future performance can be measured.

IsoEnergy's environmental achievements in 2024 demonstrate the company's commitment to minimizing operational impacts while advancing project development. The achievement of zero significant environmental incidents across all projects provides investors with confidence in the company's operational discipline and risk management capabilities.

The company initiated baseline environmental studies at Larocque East, a critical step in the permitting process that will guide future project design with environmental impact minimization as a core objective. This proactive approach to environmental planning reflects industry best practices and positions IsoEnergy favorably for regulatory approval processes.

Operational improvements at the Tony M Mine included targeted infrastructure upgrades that improved water efficiency and reduced emissions, demonstrating the company's commitment to continuous improvement in environmental performance. The reclamation of all active exploration sites and enhanced waste management practices with goals of reducing material waste further reinforce IsoEnergy's environmental stewardship approach.

Community Engagement & Indigenous Partnerships

IsoEnergy's community engagement strategy centers on meaningful partnerships with Indigenous communities and local stakeholders. The company maintained strong Indigenous representation in its workforce, with 63% at Matoush and 36% at Larocque East, demonstrating authentic commitment to Indigenous employment and economic participation.

The company's support for community well-being initiatives includes contributions to the Northlands College Scholarship Foundation and JZ Memorial Fund, reflecting long-term investment in regional education and social development. These partnerships extend beyond regulatory compliance to create sustainable community relationships that support long-term operational success.

Company-wide policy implementation covering Health and Safety, Respectful Workplace, and Diversity provides a standardized framework for operations across all jurisdictions. The standardization of incident investigation reporting across exploration projects ensures consistent safety protocols and continuous improvement in operational practices.

Governance Enhancement & Corporate Integrity

IsoEnergy's governance strengthening initiatives reflect the company's commitment to meeting institutional investor expectations and regulatory requirements. The adoption of new oversight measures, including Corporate Governance Guidelines and Majority Voting Policy, aligns the company with modern corporate governance standards.

The achievement of 100% Code of Ethics compliance reinforces a culture of integrity throughout the organization, a critical factor for investors evaluating management quality and operational risk. Continued strong Board oversight on risk management, cybersecurity, and sustainability ensures comprehensive governance coverage of material business risks.

In the news release, Philip Williams, CEO and Director of IsoEnergy, provided comprehensive commentary on the company's sustainability approach and future direction.

"This inaugural Report underscores our commitment to responsible resource development and highlights the concrete steps we have taken to reduce our environmental footprint, invest in local communities and businesses, and strengthen partnerships with Indigenous Nations."

Williams emphasized the central role of sustainability in the company's growth strategy:

"As we continue advancing our projects, sustainability remains central to how we plan to operate and grow. Looking ahead to 2025, our focus is on formalizing IsoEnergy's sustainability approach by developing a robust ESG framework to guide, manage, and track performance on material ESG issues."

This forward-looking statement provides investors with insight into management's strategic priorities and the company's commitment to systematic ESG integration across all operations.

2025 ESG Framework Development Strategy

IsoEnergy's planned ESG framework development for 2025 represents a significant strategic initiative that will formalize the company's sustainability approach. The comprehensive materiality assessment planned for 2025 will identify and prioritize ESG issues most relevant to IsoEnergy's operations and stakeholder interests.

The development of a company-wide sustainability policy will provide standardized guidelines for decision-making across all projects and jurisdictions. This systematic approach to ESG integration positions IsoEnergy to meet evolving regulatory requirements and investor expectations while maintaining operational flexibility.

The formal ESG framework will enable comprehensive performance tracking and reporting on material ESG issues, providing investors with enhanced transparency and accountability regarding the company's sustainability performance.

Asset Portfolio & Production Positioning

IsoEnergy's diversified asset portfolio provides investors with exposure to multiple uranium development timelines and production scenarios. The Larocque East project represents the company's primary near-term development focus, with the Hurricane deposit offering significant resource potential in a premier mining jurisdiction.

The Utah portfolio of permitted past-producing mines provides unique optionality for rapid production restart as market conditions warrant. The toll milling arrangement with Energy Fuels eliminates processing infrastructure requirements, reducing capital expenditure needs for production restart.

This diversified approach to asset development provides investors with multiple value creation pathways while maintaining financial flexibility through varying capital intensity across projects.

For Investors

The inaugural sustainability report positions IsoEnergy favorably for institutional investor evaluation, particularly as ESG considerations become increasingly important in investment decision-making. The comprehensive approach to environmental management, community engagement, and corporate governance demonstrates operational maturity and reduced regulatory risk.

However, investors should consider the forward-looking nature of many sustainability commitments and the potential for implementation challenges as the company advances toward production. The success of the 2025 ESG framework development will be critical in demonstrating the company's ability to translate sustainability commitments into operational performance.
