The Crin occurrence is centred on a trenched area, located approximately 3 kilometres west of Razorback Mountain and approximately 24 kilometres north-northwest of Germansen Landing (Open File 1990-17). This occurrence has similar regional geology to that of the Biddy occurrence (093N 114).

This occurrence is found in the upper part of the Middle Devonian Otter Lakes Group, near the contact with the overlying Upper Devonian-Lower Mississippian Big Creek Group shales.

Massive to disseminated sphalerite and galena occur in the Otter Lakes Group dolomites. The showings are relatively poorly exposed and poorly documented. Sphalerite occurs as disseminated grains in fine-grained dolomite and as brecciated pods in arenaceous dolomite. Galena primarily occurs massively with barite in small, localized shear zones with vary in amounts of sphalerite. The host rocks are primarily dolomites and dolomitic breccias of the McDame Group (Fieldwork 1990-01, p. 112). The showings are relatively poorly exposed and poorly documented.

Work History

Geochemical soil sampling completed in 1973 by Newcastle Explorations for Cominco Ltd. (Assessment Report 04815) revealed anomalous zinc values over the Crin claims and confirmed with low-grade showing already known.

In 1975, further geochemical soil sampling by Far Out Enterprises for Cominco Ltd. on the CRY group located a large lead-zinc anomaly that was interpreted to be downslope dispersion from two known lead-zinc showings (Assessment Report 05729).

A map of work done in 1976 on the Crin Area North shows trenching done on and surrounding the occurrence, but no results were provided (Property File 016346).

An extensive geophysical survey was carried out in 1991 over the Echo and Whistler claims, but no interpretation of results was offered (Assessment Report 22362).

In 2006, a detailed historical compilation of geochemical soil surveys that included the 1973 work on the Crin soil grid areas (Assessment Report 04815) was completed by B.K. Bowen of Surrey, British Columbia (Assessment Report 28634). No specific work was done on the Crin occurrence.

In 2007, a prospecting survey was done by B.K. Bowen of Surrey, British Columbia on the Echo claims, which encompass the Crin occurrence, but no work was done on the occurrence itself (Assessment Report 29107).
