Gradient’s Patua project is located approximately 38 miles east of Reno and about 10 miles east of the town of Fernley. Five currently operating geothermal power plants are located within 30 miles of the Patua project. To ascertain the electric power potential of its leases at Patua, Gradient has undertaken an extensive exploration program consisting of geological, geochemical, and geophysical surveys, core hole drilling, well drilling, and well discharge testing.
The Patua project is characterized by the presence of surface manifestations indicative of high temperatures near the surface, including 13 hot springs ranging in temperature from 82F to 204F. In 1962, Magma Power Company drilled three shallow exploration wells at Patua ranging in depth from 300 ft to 750 ft with a reported maximum temperature of about 270F.
Currently, Gradient is focusing its’ development efforts on the southwestern portion of the Patua geothermal leases. Construction on the Patua Geothermal Power Plant site began during Q3 2011, with commercial operations slated for December, 2013.
