The BOLIVAR EAST prospect is located on the east side of Bolivar Creek, approximately 14 kilometres west-northwest of Peachland.

The area 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 intrude the Nicola Group rocks. These intrusive rocks outcrop several hundred metres to the south.

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 entire 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 following 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, BOLIVAR ROAD (082ENW100), BOLIVAR CREEK (082ENW101), IRON HORSE (082ENW025), and CAP (082ENW026).

In 1988, a joint venture between Fairfield Minerals Ltd. and Placer Dome Inc. funded a 6000 metre reverse circulation drill program. In the BOLIVAR EAST area 1 inclined and 5 vertical holes were drilled for a total of 758.81 metres. Holes were spotted to test gold soil anomalies and gold showings in fractured volcanics and skarn exposed in trenches. Gold assays from 3 holes exceeded 0.5 gram per tonne (Assessment Report 18711). The best intersection, 7.07 grams per tonne gold over 1.52 metres in hole 88-32, was associated with a fine to medium-grained siliceous rock (Assessment Report 18711). Elevated gold values were found throughout the section which was taken as evidence of structural control on mineralization. All intersections with gold values of greater than 0.5 gram per tonne had associated pyrite and in hole 88-31, a trace of arsenopyrite.

In 1994, a hole (170 metres) was drilled to test mineralization previously detected in drilling. The hole intersected 16.2 grams per tonne gold over 1.0 metre, within a 2.5-metre section averaging 9.38 grams per tonne gold (Assessment Report 24026). The values occur in an altered zone of sericitized and silicified sheared mudstone and greywacke; a flake of visible gold and traces of pyrite and arsenopyrite occur.
