LurraAtlas

950 Pre-Screened Sites.
15 States.

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
