VANCOUVER, B.C., CANADA, July 22, 2009 -- Magma Energy Corp. (TSX: MXY) ("Magma") announces the successful completion of its first slim hole that tested the geothermal reservoir at its Maule property, 300 km south of Santiago in Chile. Temperatures exceeded 200 degrees Celsius at a depth of 650 meters below surface. Drilling of the US$1.6 million slim hole followed a US$400,000 magnetotelluric geophysical program carried out in March 2009 which outlined a large anomaly in the vicinity of surface fumaroles sampled by Magma earlier in the year. Gas and steam condensate samples from these fumaroles were analyzed and indicate that deep reservoir temperatures may exceed 290 degrees Celsius.

These encouraging results have enabled Magma's consultants Sinclair Knight Mertz ("SKM") to estimate an Inferred Resource of 7000 petajoules ("PJ") of thermal energy in place, relative to 40°C, that is estimated to be capable of producing 140 megawatts ("MW") of electrical generation for 30 years. The resource estimate has been prepared in accordance with the Code for Geothermal Resources and Reserves Reporting (the "Code") 1st Edition: 2008, published by the Australian Geothermal Energy Association. The report was prepared by Philip James White who is responsible for its content. Dr. White, a Senior Geologist with SKM, is a "Competent Person" under the Code, a member of the Society of Economic Geologists and is independent of Magma.

The slim hole results and the resource estimate are being used as the basis for Magma's submission of a geothermal development plan to the Chilean Government for a 50 MW power project at its Maule property. Approval by the Chilean Government will enable additional drilling and infrastructure development to begin later in 2009.
