The Bristol 11 occurrence is located on high ground west of Tommy Creek at an elevation of approximately 1850 metres.

The area is underlain by Mississippian to Jurassic Bridge River Group cherty sediments and basaltic greenstones that strike north east, dip steeply northwest and are intruded by a stock of Cretaceous to Tertiary Bendor pluton granodiorite. Tertiary (?) porphyry dikes and a mafic dike also cut the metasediments.

Locally, carbonitized and silicified shear zones in basaltic volcanic rocks and argillaceous sediments host quartz veining with pyrite, chalcopyrite and realgar mineralization. The structure is reported to strike approximately 220 degrees with a dip of 29 degrees north. In 1991, a sample traverse assayed 1.69 grams per tonne gold over 8 metres, including rock chip samples yielding up to 3.65 grams per tonne gold and 0.296 per cent zinc over 1.0 metre (Assessment Report 22573).

Another similarly mineralized steeply dipping shear zone hosted by basalt flows, tuffs and argillite is located approximately 250 metres to the west. In 1991, two rock chip samples (148062G and 148054G) assayed 0.42 and 1.33 grams per tonne gold, respectively (Assessment Report 22573).

In 1995, a rock sample (94SS R06) from the area assayed 0.824 per cent copper and 8.4 grams per tonne silver (Assessment Report 23625).

The area has been historically explored in conjunction with the Bristol (MINFILE 092JNE071) prospect. In 1992, Westmin Resources Ltd. completed a program of geochemical sampling and geological mapping on the area as the Bristol 11 claim. In 1995, a program of rock and soil sampling was completed on the area by Levon Resources Ltd. as part of the Silverside Extension claim.
