Environmental Metrics

ESG Focus Areas

• Responsible Mine Development

Environmental Achievements

• Developing mine and site infrastructure plans that avoid new stream and riparian area disturbances and crossing, and, to the maximum possible extent, staying within existing historical project disturbance areas
• Developing reclamation and closure plans that adopt successful historical reclamation practices and improves-upon post-closure water management and treatment practices, including incorporating membrane cover systems into waste rock storage facility designs
• Utilizing low carbon emissions grid hydro power

Social Achievements

• Prioritizing hiring locally, building an internal team, and contracting with external consultants, contractors and suppliers, that are Lemhi County and Idaho-based, and when those resources are unavailable, looking to neighboring States to bolster the project team

Climate Goals & Targets

Environmental Challenges

• Risks associated with potential mine development include sensitivity to gold price and permit delays
• The project considers refurbishing and reusing much of the existing recovery plant and infrastructure. There is a risk that the refurbishment costs would exceed budgeted estimates
• The Beartrack site is serviced by an existing Idaho Power Co. 69 kV power transmission line with limited excess capacity and with power available on a first come, first served basis
• To account for the long leach tail observed during historical Beartrack operations, the metallurgical recovery calculated from column leach testing was increased by 2.3% of contained gold (approximately 11,000 ounces of gold in total) for Beartrack oxide and transition ores. Although the data supports this assumption, there is a risk that this added recovery may not be realized or may be delayed relative to the economic model assumptions

Mitigation Strategies

• Additional heap leach metallurgical test work to verify recoveries and reagent requirements at Beartrack and assess the potential for run-of-mine leach at Haidee
• Additional hydrogeologic characterization to refine the current estimates on the site-wide water balance and pit lake modeling
• Additional environmental geochemistry characterization to support operational waste management planning and closure design
• The current environmental baseline study program should be maintained to prepare for permitting and NEPA review of the first phase heap leach restart project
• The development of a Plan of Operations in support of permitting the heap leach restart project
• A feasibility study should be completed on the heap leach restart project once supporting lab and field studies referenced above have been sufficiently advanced
