The Babcock Lake property is located between Mount Tinsdale and Turks Nose Mountain, approximately 20 kilometres east-southeast of Barkerville. Access is by logging roads approximately 45 kilometres from Barkerville via the Cunningham Creek road.
The property is mainly underlain by northwest striking, folded and faulted olive brown weathering mudstones, and black carbonaceous in part siliceous or phosphatic mudstones and siltstones with minor interbedded amygdaloidal volcanics, quartzite and orange weathering siltstones of the Cambrian-Mississippian Black Stuart Group. To the east with an unconformable contact lies limestone and dolomite of the Lower Cambrian Mural Formation (Cariboo Group) and black shale, green phyllite and limestone of the Upper Cambrian Dome Creek Formation (Cariboo Group).
Mineralization observed is disseminated to lenticular to banded pyrite, nodular phosphatic rock and fine nodular baritic rock. Quartz-chalcopyrite veinlets were also observed in quartzite of the Black Stuart Group. Rock sample R236 from a black mudstone analyzed 0.18 per cent zinc (assumed to be sphalerite), and nearby rock sample R235 of a quartz-ankerite vein yielded 13.4 grams per tonne silver (Assessment Report 15366).
The Tinsdale claims were staked in July 1985 by Cominco Ltd. to cover zinc and barium silt anomalies on Babcock Creek from data acquired by the government Regional Geochemical Survey published in June 1985. Preliminary soil sampling and rock sampling along logging roads produced two areas with zinc values to 3360 parts per million in soil. In 1987, contour soil sampling and road bank soil sampling was completed. The objective of a 1988 grid soil sampling survey was to outline geochemically anomalous patterns in anomalous areas outlined by the road bank soil survey conducted in 1987. Cominco assessment credits on the Tinsdale 1 and 2 claims ran out on August 2, 1990 and the property was dropped. The Rae properties were staked in August and September of 1993 with follow-up staking in the spring of 1994 by R. Jalbert (Yarlo Resources); prospecting and a self-potential survey was conducted in 1993-94.
