Geothermal Drilling Planned for Pumpernickel Project, Nevada

Sierra Geothermal Power Corp. has an option to acquire a 50% interest in the Pumpernickel Geothermal Project from Nevada Geothermal Power. Work is anticipated to commence upon permitting approval.

The Pumpernickel site has been identified as one of the top geothermal prospects in Nevada by David Blackwell, PhD, a geothermal heat flow expert considered the world's foremost expert in temperature gradient analysis.

Widespread geothermal fluids are being channeled to the surface (hot springs) through range-front faults, which suggests potential for an electricity-grade geothermal resource. Combined data from the previously drilled wells define a field of at least 1.5 by 3.5 kilometers (km) with thermal gradients greater than 100 degrees C/km.

Sierra Geothermal has secured a portfolio of 15 geothermal projects in various stages of development and intends to advance the development of its portfolio of projects through a combination of equity and/or joint venture partnerships; it also plans to continue evaluating additional acquisitions.
