Climate Change Data

Environmental Metrics

ESG Focus Areas

• Environmental
• Social
• Governance

Environmental Achievements

• Technical reports conclude that the Idaho-Maryland Project has no significant environmental impacts after mitigation has been incorporated.

Social Achievements

• Creation of approximately 58 acres of level and useable industrial zoned land for future economic development in Nevada County.
• Approximately 300 employees would be required when the mine reaches full production.

Governance Achievements

• Participation of numerous highly qualified independent consultants in technical reports.

Climate Goals & Targets

Environmental Challenges

• Potential impacts related to aesthetics, air quality, dust, biological resources, cultural resources, geology and soils, hydrology and water quality, land use and planning, noise and vibration, and transportation and traffic.

Mitigation Strategies

• Detailed mitigation plans were developed and implemented to address each potential impact, including dust mitigation, use of Tier 4F engines, compensatory mitigation for wetlands and stream impacts, preservation of special status plants, historic documentation sharing, groundwater monitoring, storm water management, noise reduction measures, and traffic management strategies.

Supply Chain Management

Responsible Procurement

• Selection of Portland cement from suppliers providing materials with low chromium content.

Climate-Related Risks & Opportunities

Reporting Standards

Frameworks Used: CEQA (California Environmental Quality Act)

Third-party Assurance: 3rd party independent consultant peer review

Environmental Metrics

ESG Focus Areas

• Air Quality
• Greenhouse Gas Emissions

Environmental Achievements

• Implementation of measures to reduce fugitive dust emissions by approximately 55%
• All off-road diesel-fueled equipment and emergency generators owned by Rise Grass Valley Inc. shall be equipped with Tier 4 Final engines.
• All underground off-road equipment shall be electrically powered

Climate Goals & Targets

Environmental Challenges

• Potential for adverse impacts to air quality due to construction and operational emissions
• Potential for objectionable odors from pumped mine water or sulfide flotation
• Potential for elevated concentrations of TAC emissions at nearby receptors
• Potential for localized CO hotspots

Mitigation Strategies

• Implementation of MM-AQ-1 (Mitigations for Use During Construction) and MM-AQ-2 (Construction Exhaust Emissions Minimization Plan)
• Implementation of APM-AQ-2 (Surface Fugitive Dust Controls)
• Implementation of APM-AQ-3 (Asbestos, Serpentinite, and Ultramafic Rock Management Plan)
• Implementation of MM-AQ-3 (Odor Abatement Plan)
• Implementation of MM-GHG-1 (Construction GHG Emissions Reductions) and MM-GHG-2 (Carbon Offsets – Construction Emissions)

Climate Goals & Targets

Environmental Challenges

• Legal challenges related to vested mining rights at the I-M Mine Property, resulting in denial of a Use Permit.
• Increased attention to environmental, social, and governance (ESG) matters, potentially leading to increased costs and reputational risks.
• Cybersecurity threats to information systems.
• Inadequate water management due to extreme weather events.
• Burdensome and expensive land reclamation requirements.
• Intense competition in the mining industry.
• Shortage of equipment and supplies.
• Risks associated with joint ventures and partnerships.
• Difficulty attracting and retaining qualified management.
• Currency fluctuations.
• Potential challenges to title of properties.
• Inability to secure surface access or purchase required surface rights.
• Potential for litigation or other claims.
• Lack of insurance coverage for all risks.
• Volatility in commodity prices.
• Uncertainties in mineral resource/reserve estimates.
• Potential for unsuccessful exploration activities.
• Significant governmental regulations affecting operations and costs.
• Climate change related physical and transition risks.
• Material weakness in internal control over financial reporting due to insufficient personnel.

Mitigation Strategies

• Reviewing litigation options to protect property rights.
• Implementing policies and processes for assessing and managing cybersecurity risks.
• Conducting environmental studies and remediation efforts.
• Seeking to obtain necessary permits and licenses.
• Developing strategies to address climate change related risks and opportunities.
• Implementing a quality control program for drill programs.
• Seeking additional financing through private placements and loans.
• Engaging in stakeholder engagement.
