The Diorite occurrence is located near Hardscrabble Creek, approximately 1.2 kilometres northwest of the creek mouth on the Skeena River.

The area is underlain by andesites of the Jurassic Hazelton Group, which have been intruded by porphyritic granodiorite dikes and stocks of the Cretaceous to Tertiary Coast Plutonic Complex.

Locally, chalcopyrite and sparse bornite occur along minor faults and fractures in the quartz-albite dike. Mineralization also occurs along the contacts of several narrow granodiorite dikes cutting the quartz-albite dike.

A selected sample assayed 4.8 grams per tonne gold, 27.4 grams per tonne silver and 2.8 per cent copper (Minister of Mines Annual Report 1929).

In 1916, 9 tonnes of ore were shipped from this property. From this ore, 454 kilograms of copper were recovered and approximately 65 cents per tonne in gold and silver were recovered (Minister of Mines Annual Report 1916, page 98).

In 2002, the Carlson group of mineral claims was staked by G.W. Kurz. During 2003 through 2014, various programs of bedrock prospecting, rock chip sampling, geological mapping, a ground self-potential geophysical survey and geochemical soil and silt sampling were completed.
