The Blue (West) occurrence is located 20 kilometres north of the townsite of Cassiar, about 120 kilometres north of the community of Dease Lake.

The showing area is underlain by an easterly dipping sequence of sediments of the Upper Devonian-Lower Mississippian Earn Group located on the southwest limb of the McDame Synclinorium. Minor lead-zinc-silver-barite mineralization is hosted by black mudstone, siliceous argillite, chert and minor shale of the Earn Group.

In 1997, rock chip sampling at the West showing yielded 0.45 per cent zinc and 0.15 per cent barium (Assessment Report 25343).

In 1981-82, grid preparation, preliminary and extensive geological mapping, and geochemical sampling were completed on the Discovery showing (104P 129) located about 3 kilometres southeast of the Blue showing. In 1984, bulldozer trenching and sampling was conducted on the Discovery showing. In 1996, the property was re-staked by Cominco Ltd. after a literature review of the previous work. A cursory site visit in 1996 confirmed similar stratigraphy as that seen at the Midway deposit (104O 038) located 46 kilometres to the north. A 1997 program concentrated on further examination of the exhalite horizon and known showings.
