Geothermal development company Mt. Princeton Geothermal LLC has commissioned Dewhurst Group to conduct an MT survey for a geothermal prospect area at Chalk Creek, Colorado.

Reported locally, “Mt. Princeton Geothermal, LLC, has commissioned a magnetotelluric survey to be conducted by Dewhurst Group, LLC, in December in the Chalk Creek area.

A public meeting to discuss the survey and surface measurements is scheduled for 7 p.m. Nov. 30 in the Sangre De Cristo Electric Association community room, 29780 N. U.S. 24 in Buena Vista.

The purpose of the survey is to verify the existence of a deep, highly conductive geothermal water reservoir.

The survey consists of 125-150 noninvasive surface measurements of deep natural electrical currents in the earth. Measurements require two 1-meter-long magnetic sensors laid on the ground and four probes positioned in the ground at depths less than 1 foot.

Magnetotelluric measurements require 2-12 hours to complete and can provide geological data to depths of 5,000 feet.

Successful verification of a viable geothermal reservoir will facilitate additional testing in 2012.

A similar survey is being considered by the City of Salida for the Poncha Springs area, also in Colorado.”
