ESG - Environmental Responsibility

Custer County and Lost River Valley residents have a fierce pride in the outstanding beauty of their surroundings, and we are doing our utmost to keep it that way. We are operating on a brownfield site, in an area with a proud mining history, where the remains of the original mining buildings still stand, and which are very much part of the local heritage. As part of the permitting process, we commissioned baseline environmental and socio-economic studies on a host of environmental factors. From 2017 to the present, these studies include:

  • Visual Resources:

    1. Analyses of the views towards the mine site from three different perspectives show very little anticipated visual impact as a result of our activities.
    2. The site of our leach pads has been carefully chosen to be out of view of the town and the highway.
    3. The leach pads will be securely lined and equipped with monitoring systems to ensure zero leakage. At the end of the mine life, the leach pads will be dried out, covered with topsoil and seeded with native grasses.
  • Environmental Issues:

    1. Wildlife & Vegetation: Our activities are not damaging to local wildlife or plant life, and will not affect the biodiversity of the area.
    2. Water: Water runoff and pollution is not a concern, as the mine is a zero discharge facility. All water will evaporate or be absorbed into the ground. The mines are dry, and are situated c. 900 feet above the water table. Despite this, we have 12 groundwater monitoring wells to establish baseline water composition prior to mine production. Water quality will continue to be closely monitored during the life of the mine.
    3. Electricity: There is already power access on the mountain. 70% of Idaho’s power comes from renewables, predominantly from hydroelectric power, and the goal is to provide 100% clean energy by 2045.
    4. Noise pollution: Our noise studies show us to be comfortably within acceptiable limits. We are not permitted to exceed a 10-decibel noise threshold beyond one mile of the mine site.
    5. Light pollution: We will be required to fit diffusers on the headlamps of trucks.
