Although no mineral-resource potential was identified in the Hells Gate Roadless Area during mineral surveys, the area is
largely underlain by a regionally extensive Proterozoic granite-rhyolite complex which is tin-bearing. The geologic setting
precludes the occurrence of fossil fuel resources and no other energy resources were identified. The potential for tin and
associated metals in the Hells Gate Roadless Area and the region cannot be fully evaluated at this point. The granophyre and
the upper part of the granite pluton along the northwestern margin of the area should be explored.
