Nevada Geothermal's Blue Mountain Well 58-15 Update

Nevada Geothermal Power Inc. (NGP) (TSX VENTURE: NGP)(OTCBB: NGLPF) announced today the completion of Well 58-15 to a depth of 5706 feet (1740 metres) at a step-out location 0.8 miles (1.2 kilometres) from production Well 26A-14. Upon completion, the well has been confirmed as a producer with geothermal fluid production between 4675 and 5603 feet (1425 and 1708 metres).

Preliminary flow tests indicate that Well 58-15 will be a high-temperature producer. The well flows unassisted at flow rates higher than previous wells and at temperatures greater than 400 degrees F (200 degrees C).

Fierce geothermal fluid flow and debris exiting from the well precluded Welaco Well Analysis Group (Welaco) from completing temperature/pressure/spinner (TPS) surveys in the open hole. The deepest Welaco data was at 1820 feet which confirmed a temperature of 404 degrees F (207 degrees C) - the highest measured temperature in any well to date at Blue Mountain.

Indications are that Well 58-15 will be as good a producer as other wells reported to date. Currently, a liner is being installed to stabilize the well and the test separator is being modified to accommodate higher flow rates. Subsequently, production testing, including flowing TPS surveys as well as injection testing, will be conducted under the supervision of GeothermEx Inc. to fully determine the production and injection capacity characteristics of Well 58-15.
