The BLUE HAWK past producer is located approximately 2.3 kilometres southwest of Wilson Landing and 12.5 kilometres north of Westbank.

The BLUE HAWK deposit occurs in a large pendant of metasedimentary rocks of the Devonian-Triassic Harper Ranch Group. These are intruded by hornblende diorite and quartz diorite of the Jurassic Okanagan Intrusions.

The BLUE HAWK property was explored and operated by the Blue Hawk Syndicate during the 1930s. Development work consisted of shallow pits, trenches, an opencut and an adit driven to the northeast from the bottom of a short shaft. In 1934, 4.5 tonnes of ore were mined which yielded 156 grams of gold and 560 grams of silver (Minister of Mines Annual Report Index No. 3, page 190). Production was entirely from the adit. By 1938 a crosscut had been driven approximately 150 metres to a vein. Drifting was reported to be in progress along the vein.

The veins, from narrow fractures to 1.2 metres thick, trend westerly to north-westerly along fractures and shears in the hornblende diorite. The veins seldom persist for more than 6 metres on strike without displacement and dissipation into the country-rocks. Many of the veins are en-echelon and are separated by shears, which also run parallel to the veins. Later bulldozer trenching exposed the BLUE HAWK vein system for a distance of approximately 180 metres. Mineralization consists of pyrite, minor galena and dark oxidation products. Traces of chalcopyrite, sphalerite and arsenopyrite are also noted in the veins, and disseminated chalcopyrite has been found in the diorite.

In 1967, Dawood Mines Ltd. of Kelowna acquired the property and over the next 7 years proceeded to carry out 400 metres of trenching, 1400 square metres of extensive stripping, geological mapping, line cutting and 18 kilometres of grid preparation, magnetometer surveys, and rock and soil geochemical surveys. Silver, copper and mercury soil geochemical anomalies were found in the vicinity of the BLUE HAWK veins and the diorite intrusions. Magnetometer anomalies were not coincident with soil geochemical anomalies. In 1980, N.C. Lenard re-sampled and evaluated the property for its similarity to the gold-bearing quartz veins of the Bralorne camp. Additional studies were carried out in 1984 by Tillicum Gold Mines Ltd. Their work confirmed the presence of auriferous pyrite in the BLUE HAWK quartz veins, but they concluded that gold values are erratic and mineralized zones lack continuity.

In 1987-88, Pinewood Resources Ltd. excavated and mapped 600 metres in trenches. They identified four directions of shearing and quartz vein mineralization. The best gold assays were associated with the north and north-west shear systems, and 3 areas were identified which produced gold assays in excess of 34 grams per tonne (Property File - Dasler P.G., 1989). These were the old original BLUE HAWK adit, Old Trench #5 located approximately 150 metres to the west of the adit, and Trench #1 approximately 75 metres north of the adit. The average assay of 10 channel samples from Trench #1, all of which assayed greater than 3.4 grams per tonne gold, was 19.39 grams per tonne gold and 67.98 grams per tonne silver (Property File - Dasler P.G., 1989). Gold assays correlated well with sulphides, especially pyrite.

In late 1988 Parkwood Resources Ltd. funded an induced polarization and resistivity survey over 7.1-line kilometres in the BLUE HAWK area. Anomalous zones were identified, including one subparallel to Jennie Creek with a minimum strike length of 1 kilometre. In 1989, Parkwood carried out trenching and a 3-hole diamond-drill program (244.8 metres) to explore the 1988 geophysical anomaly. The drill program found that the geophysical anomaly was caused by the presence of graphitic sediments and, locally, andesite, with weak disseminated pyrite and pyrrhotite mineralization. In 1991, Pinewood extended a soil sample grid to the north of known mineralization; however, it was unsuccessful in identifying new exploration targets. Drilling (5 holes, 610 metres) in 1993 attempted to intersect down dip extension to surface veins; results were poor (Assessment Report 23811).
