LurraAtlas
Abandoned hard rock mines are not scarce. The United States holds thousands across western and upper midwest mining belts. LurraAtlas is our proprietary site database, evaluating each candidate against six critical criteria.
Hydraulic Head
Minimum 300m net head required for economic generation
Mine Depth
Minimum 1,000 ft — deep shafts provide natural head advantage
Cavity Geometry
Sufficient volume for dual-reservoir storage at economic scale
Hydrogeology
Groundwater management viability and water source analysis
Transmission
Proximity to grid interconnection or direct BTM customer load
Ownership
Clear title structure — municipal, state, or federal mine owners preferred
