The FAP showing is located on the north side of Trout Creek, approximately 12 kilometres west of Summerland.

The showing occurs in a body of amphibolite gneiss within quartz diorite of the Jurassic Okanagan Intrusions. Mineralization consists of copper, lead, zinc, silver, and gold in quartz veins and shear zones in a northwest striking band of amphibolite gneiss. The zone dips easterly between 25 and 50 degrees, has a thickness of about 15 metres and has been traced northwesterly along strike for approximately 200 metres. Early reports refer to carbonatites and alkalic metasomatism (fenitization) but these were not substantiated by later geological work.

Early exploration on the FAP property is thought to have taken place in the 1930s, when a short adit was driven into the limonite zone. The adit has since caved and been lost. During the period 1968-70, Austro-Can Exploration Ltd. (later changed to Agio Resources Corp.) carried out a program of bulldozer trenching, geological mapping, soil sampling, magnetometer studies and 3 drillholes. No assessment records were filed on this work and the results are unknown. In 1969, an airborne magnetometer survey was flown over the area. Gross geological features were identified by the survey. In 1970, geological mapping, geochemical surveys, and a ground magnetometer survey were carried out. Diamond drilling of 3 holes for a total of 335 metres was done on the eastern margin of the mineralized zone. The best intersection was between 46.5 metres and 49.8 metres depth in hole C-1. This section averaged 1.37 grams per tonne gold and 27.4 grams per tonne silver, 1.3 per cent lead, 0.33 per cent copper (Property File - Mitchell, J.A.(1972): Report on Crump Group, page 7). Mineralization exposed in trenches was observed to consist of chalcopyrite in veinlets and as disseminations between veinlets, and associated with magnetite, ilmenite and pyrite. In 1973, an electromagnetic survey was completed which outlined a major conductor. In 1975, a single 42-metre hole was drilled in the vicinity of the trenches. In 1982, additional geochemical sampling and prospecting was carried out. Two copper anomalies were identified. In 1983, diamond-drill hole 83-1 was completed to a depth of 62.4 metres. The hole encountered amphibolite gneiss with some minor shearing, bleaching and quartz veining. In 1985, an induced polarization survey was carried out. The survey identified chargeability anomalies; however the shear zone in the vicinity of the trenches did not have a definite response.

In 1986 detailed geological mapping reinterpreted the FAP showing as a mineralized shear zone which is hosted by a lens-shaped hornblende gneiss body. It was speculated that this may be part of a Proterozoic basement gneiss, similar to the Monashee gneiss normally only seen to the east of Okanagan Lake. Within the gneiss there is a strongly developed foliation and mafic minerals are typically altered to secondary chlorite. The main mineralized area is zoned into a chlorite-rich border, an outer quartz-carbonate-mica zone and an inner siliceous gossan. Pyrite and chalcopyrite are typically associated with quartz and quartz-carbonate veinlets in the quartz-carbonate-mica zone. The geological study concluded that the FAP showing is a fracture zone cutting basement amphibolites which have been metasomatically altered by the intrusion of a small ultrabasic to gabbroic plug and by quartz veining associated with hydrothermal fluids derived from the adjacent batholithic intrusions.

In 1987, 1 diamond-drill hole (68.8 metres) was undertaken to test the IP anomaly identified by the 1985 geophysics survey. The drill intersected pyrite and a conductive clay gouge in an east trending fracture zone. No other mineralization was observed and none of the drill core was analysed. In late 1988 a 4-hole drill program was carried out to test the main zone (DDH 88-1/148.4 metres), and the VLF-EM anomalies first outlined in 1973 (DDH 89-2, 89-3, 89-4/194.4 metres). The first hole failed to intersect mineralization, the others intersected a quartz vein stockwork with associated wallrock alteration. Mineralization consisting of pyrite, chalcopyrite, sphalerite, galena and a conductive clay gouge was found in the areas of the VLF-EM anomalies. Assay values ranged up to 1.7 grams of gold and 83.6 grams of silver per tonne, and 1.69 per cent copper over narrow widths (Assessment Report 18710).
