The OKA 8 showing is located on the east side of Bolivar Creek, approximately 15 kilometres west-northwest of Peachland.

The showing is underlain by a pendant of Triassic-Jurassic Nicola Group andesite and lesser interbedded hornfelsed sediments and skarn. Granodiorite and diorite of the Early Jurassic Pennask Batholith outcrop about 100 metres to the southwest.

Exploration in this area, for gold bearing quartz veins and shear zones, dates back to the 1890s when the ALMA MATER (082ENW017) and the SILVER KING (082ENW018) were developed. During the 1960s and early 1970s the area west of Okanagan Lake was subject to a major exploration effort directed at copper-molybdenum porphyry deposits.

Beginning in 1986 the gold potential of Nicola Group skarns was investigated by Fairfield Minerals Ltd. During the next 2 years Fairfield carried out a major program of soil sampling, prospecting, linecutting, geological mapping, magnetometer surveys, trenching and 6000 metres of reverse circulation drilling. Exploration focused on a number of mineral occurrences within the Nicola Group, including: BOLIVAR WEST (082ENW098), BOLIVAR EAST (082ENW099), BOLIVAR ROAD (082ENW100), IRON HORSE (082ENW025), and CAP (082ENW026).

A prospecting program in 1986 located a quartz vein on the OKA 8 claim near the west end of the Bolivar Creek road. Chip samples, 0.45 to 0.80 metre long, taken across the quartz vein assayed from 0.07 to 1.57 grams per tonne gold (Assessment Report 15834). A grab sample from the same area assayed 23.0 grams per tonne gold and 5.47 grams per tonne silver (Assessment Report 15834). High-grade samples contained arsenopyrite.
