The granodiorite was obtained at ~2. 5 km depth in a geothermal drillhole sited within Medicine Lake caldera (sample supplied by CalEnergy Corp.).

Objectives of this program are to infill areas of low drillhole density, to confirm a new structural model for the deposit, and to test new exploration targets that are based on this structural model.
