Lower Jurassic Hazelton Group green and purple andesites with some interbedded tuffs are separated from the green and red tuffs in the Nilkitkwa Formation by a fossiliferous limestone horizon. The tuffs are generally fine-grained and massive, but some beds are well laminated and strike easterly with a dip of near vertical to 50 degrees north. The northern dipping sequence is likely overturned. The Hazelton Group rocks are intruded by a Bulkley Intrusive granodiorite stock of Cretaceous age. The stock is cut by a 9 metre wide lamprophyre dike which dips at a low angle to the south.

A mineralized quartz-carbonate vein exists in a sheared zone in the granodiorite stock. The vein strikes 080 degrees east and dips 83 degrees north. The sheared and altered rock is traversed by sulphide stringers and seams comprised of pyrite, arsenopyrite and pyrrhotite. Some of the pyrrhotite is partly replaced by lamellar marcasite within carbonate veins. A 30 centimetre channel sample taken across the central portion of the vein at the portal adit assayed 5.14 grams gold and 98.06 grams silver (Geological Survey of Canada Memoir 223, pages 65 to 69).

WORK HISTORY

The Copper Queen claim, as part of the Iron Vault (Silver Creek) property (093L 098) was held by Peter Schufer and Leeman Wood from about 1907. The claim was Crown-granted in 1914. No work has been reported on the Copper Queen showings.

In 2011, a surficial exploration program was completed on the Hudson Bay Mountain property by Lions Gate Metals Inc from June to August 2011. Focus was given to locating and testing historical showings and investigating areas outlined by the 2008 Quest West airborne survey. Historic mineral occurrences on the property are: King Tut [093L 087] (prospect); Bonanza [093L 096] (showing); Silver Lake (L.7239) [093L 097] (Past Producer); Iron Vault (L.5754) [093L 098] (Past Producer); Mammoth (L.7249) [093L 100] (Prospect); Copper Queen (L.5751) [093L 101] (Developed Prospect); Josie (L.7251) [093L 229] (Prospect); and Silver Lake 2 (L.7240) [093L 231] (Past Producer).

Silt samples were collected from creeks within and draining the property and several soils grids were completed over areas of interest. A total of 122 rock samples were collected and submitted for assay over the 2011 field program. Samples were collected from areas of known mineralization as well as new areas. Results obtained from samples collected from known showings support historical results. Rocks samples were collected from King Tut, Iron Vault, Copper Queen, Josie, Silver Lake 2 and Silver Lake. Efforts were made to locate the Mammoth, Rachel, Vancouver and Bonanza showings but were considered unsuccessful.
