The B46 (Locality C) showing is located on the north eastern slopes of Mount Hayes, located between Ramsay Arm and Toba Inlet, at an elevation of approximately 1300 metres.

The area is underlain by intrusives of the Jurassic to Cretaceous Coast Plutonic Complex. Samples from 10 kilometres west on Bute Inlet give an age date of 97 to 99 million years by potassium-argon from biotite and hornblende (Geological Survey of Canada Open File 480).

Locally, disseminated chalcopyrite is found in a fracture zone in slightly silicified and pyritized diorite. Wide spread areas of intense silicification, pyritization and chloritization of the diorite are evident. Many sites containing chalcopyrite in float have been identified, but only at one location in outcrop.

In 1970, a 1.22 metre chip sample from the mineralized outcrop at Locality C assayed 0.22 per cent copper, while float samples (from Locality D) assayed up to 1.53 per cent copper and 35.3 grams per tonne silver (Assessment Report 3133).

In 2007, a rock sample (GHR01-71) from a mineralized mafic intrusive, located near a small creek to the south east, assayed 0.579 per cent copper and 4.9 grams per tonne silver. Another sample (GHR01-56) of quartz vein material assayed 0.034 per cent molybdenum (Assessment Report 30384).

In 1970, the area was prospected and mapped as the B and C claims. In 2007, Archangel Resources took rock samples from the area. In 2010, AZ Copper completed a program of rock and soil sampling.
