In light of the cuttings and geophysical logs from the Campbell E-2 hole, it seems unlikely that a geothermal reservoir exists in the horst block of the Humboldt House area. All known sinter deposits occur in the graben block in the valley, northwest and southwest of Campbell E-2. The range front fault, which may serve as a conduit for deeply circulating fluids, dips to the west and intersects the hole at 890 feet (271.3 m). The presence of sinter deposits and the deeper extension of the fault to the west suggest that the geothermal system may be located to the west of the Campbell E-2 hole. The Grass Valley Formation and the Auld Lange Syne Group in general are fine-grained argillaceous and slaty rocks these rocks have a very low intergranular permeability and may not be competent enough to maintan a significant fracture permeability necessary for a geothermal reservoir rock.
