The Bridge occurrence is situated on the south side of the Deadman River (Deadman Creek), approximately 2.8 kilometres southwest of Beaver Lake, 7 kilometres southeast of the Vidette gold mine (MINFILE 092P 086) in the Deadman Valley, 50 kilometres north of Savona.
The occurrence is underlain by argillite and andesite of the Upper Triassic Nicola Group that are exposed in a window through the Miocene plateau basalts, which blanket most of the surrounding area. The argillite is interbedded with andesitic tuffs, augite porphyry and minor agglomerate. Nicola Group rocks are intruded by biotite quartz diorite, which is probably part of the Triassic to Jurassic Thuya batholith (Geological Survey of Canada Memoir 363). Nicola rocks are unconformably overlain by lacustrine and fluviatile sediments and volcanic ash of the Miocene Deadman River Formation to the west in the Deadman Valley. The youngest bedrock formations are Miocene olivine basalt flows of the Chasm Formation (Chilcotin Group).
Mineralization is hosted by quartz veins in medium-grained biotite quartz diorite. Gold and silver occur associated with quartz vein alteration envelopes and as high-grade narrow veins. Overall, the rock is weakly altered. Hornblende is commonly altered to chlorite and veins have up to 20-centimetre-thick alteration envelopes of intense bleaching and weak pyritization. Fractures dominantly strike 160 degrees and dip 60 degrees west. Pyrite and arsenopyrite-bearing quartz vein strike 160 degrees and dip 60 to 80 degrees west.
The discovery of the Vidette gold mine in the 1930s sparked exploration interest in the area. The earliest known work on the property dates from the 1930s, or possibly earlier, when prospecting pits were excavated on some of the showings.
The Precisely claims were staked by Michael Dickens in 1983 following the discovery of gold-bearing quartz stockworks. The property was optioned by Inter-Pacific Resource Corporation. In 1984, MineQuest Exploration Associates Limited carried out a program of geological mapping, prospecting, rock-chip sampling, soil sampling (1286 samples), line-cutting and magnetometer and very low-frequency electromagnetic geophysical surveying on behalf of Inter-Pacific Resource. In 1985, MineQuest Exploration carried out an additional program of rock-chip sampling, soil sampling, line-cutting, induced polarization, magnetometer and very low-frequency electromagnetic geophysical surveying, reverse circulation percussion drilling and diamond drilling. In total, 20 reverse circulation drill holes totalling 9005 metres and four NQ diamond drill holes totalling 183 metres were completed on the property, 12 of which intersected zones of mineralized quartz veining and alteration in quartz diorite. Of those 24 drillholes, 15 of them were drilled at the Bridge showing. Drillhole 85-10, the only diamond drill hole drilled at the Bridge showing, targeted the north end of an induced polarization anomaly.
Placer Development Limited later re-optioned the property from Inter-Pacific Resources Limited and in 1986 completed additional induced polarization surveys and four diamond drill holes totalling 526 metres. In 1987, Placer Development completed additional rock-chip and soil geochemical surveying, geological mapping and magnetometer and very low-frequency electromagnetic geophysical surveying. In total, 29 rock samples, including five float samples, were collected and sent for assay; however, the assays did not return any significant results.
The property was later acquired by Johan T. Shearer as the High Ox property. Between 2010 and 2011, Shearer conducted an exploration program consisting of area reconnaissance, road traverses and prospecting on behalf of Homegold Resources Limited. The property was then optioned to Clear Creek Ventures Limited in late 2011. Between December 2011 and May 2012, on behalf of Clear Creek Ventures, Shearer completed a program of prospecting and very low-frequency electromagnetic and ground magnetic geophysical surveying. Later in 2012, Shearer conducted additional prospecting on the property.
In 1985, the original Bridge showing was extensively sampled, along with the creek exposure and outcrop found west of Deadman Creek. At the original showing, eleven 1-metre chip samples were collected, six of which assayed between 0.09 and 1.95 grams per tonne gold for an average of 0.733 gram per tonne gold over an apparent width of 6 metres (Assessment Report 15143, page 16). Sample material included quartz veins and altered and unaltered quartz diorite. Approximately 100 metres to the north, three consecutive samples composed of vein material, alteration selvages and unaltered quartz diorite, and collected from an exposure in Deadman Creek, assayed 0.24, 0.5 and 1.6 grams per tonne gold (Assessment Report 151434, page 17).
From the 1985 drill program, drillhole 85-4 assayed 4.7 grams per tonne gold and 25 grams per tonne silver over an interval of 3.05 metres (Assessment Report 15143, page 24).
