The FOB showing is located at 740 metres elevation near the east bank of the Ashnola River (Assessment Report 6173). Keremeos, British Columbia lies 13 kilometres to the east-northeast.
The showing was staked and explored in 1976 and 1977 by Consolidated Kalco Valley Mines Ltd. Exploration initially consisted of geological mapping, geochemical soil surveys and magnetometer, electromagnetic and self potential geophysical surveys. This was followed up by three surface diamond-drill holes on the FOB 2 claim, totalling 322 metres.
The oldest rock units in the area are Carboniferous to Triassic Old Tom and Shoemaker formations. These consist of chert, argillite, mafic volcanic flows and minor limestone beds. The Old Tom and Shoemaker formations have been intruded by the Middle Jurassic Similkameen intrusive. The composition varies from hornblende diorite to quartz diorite. Intrusive dike swarms have accompanied the Similkameen intrusion. Pervasive regional metamorphism is of upper greenschist to lower amphibolite facies. Superimposed on top of this is a later thermal contact metamorphism.
The showing consists of molybdenite and minor chalcopyrite mineralization hosted in andesitic tuff, greenstone, grey feldspar porphyry dikes and granodiorite.
The best molybdenite values from drilling were from holes KV #1 and KV #3. Drillhole KV #1 yielded 0.10 per cent MoS2 (0.06 per cent molybdenum) over the 10-metre interval between 480 and 490 metres (Sample 10468) (Assessment Report 6173). From drillhole KV #3, sample 830 yielded 0.21 per cent MoS2 (0.12 per cent molybdenum) over the 10-metre interval between 20 and 30 metres (Assessment Report 6173). In the same hole, sample 867 yielded 0.19 per cent MoS2 (0.11 per cent molybdenum) over the 10-metre interval between 240 and 250 metres (Assessment Report 6173).
