Magma Energy (United States) Corporation (MEC) would demonstrate the potential geothermal resource at the McCoy geothermal area in Churchill County, Nevada (NV). In Phase 1 (exploration geophysics), Magma would collect and interpret resistivity data from both Magnetotelluric (MT) and Controlled-Source Audio-Magnetotelluric (CSAMT) electrical surveys, and conduct detailed geologic mapping. Once collected, data would be integrated into MEC's geographic information system (GIS). This data would be used by MEC to target the thermal gradient and production wells to be drilled in Phase II. This analysis is Phase I only.
