The Rice B mineral occurrence is located at 1158 metres elevation on the west side of Rice Creek. The Dayton occurrence (082ESW022) is located 1 kilometre to the south. Bridesville, British Columbia lies 7 kilometres to the southwest.
Lithologies covering the Rice occurrence include metasediments and metavolcanics of the Carboniferous to Permian Anarchist Group. Quartzite with interbedded pebble conglomerate and lesser greenstone and black argillite comprise lithologies. The black argillite contains disseminated graphite and pyrite. Diorite of the Middle Jurassic Nelson intrusions locally intrudes the Anarchist Group metasedimentary-metavolcanic sequence.
The Rice B occurrence consists of a mineralized, fissure-vein exposed at two locations approximately 500 metres apart. The first (south) exposure consists of a fissure zone trending 080 degrees in highly sheared limy greenstone. Intense fracturing is vertical with a strike of either 020 or 080 degrees. Quartz and quartz-calcite fracture fillings are 2 to 4 centimetres wide containing pyrite. Wallrocks are intensely silicified with up to 1 per cent pyrite. The second (north) exposure strikes 040 degrees and dips 70 degrees west. Narrow chert breccia zones are developed along strike hosting numerous, crosscutting silicified fractures with a strike of 134 degrees. Fractures are either quartz or quartz-carbonate filled with intense silicification, hematization and brecciation. Greenstone and chert wallrocks have been altered to chlorite schist in places.
The best assay results from this occurrence were from sample MOD-83-121R taken in 1983. The sample yielded 0.152 gram per tonne gold, 6.1 grams per tonne silver and 0.27 per cent copper (Assessment Report 13563). A second sample, AF-83-05, yielded 0.152 gram per tonne gold, 0.970 gram per tonne silver and 0.068 per cent copper from a very fine grained quartz vein with minor chalcopyrite, galena and 2 per cent pyrite. The vein was exposed over 2 metres in a trench hosted in the fissure zone (Assessment Report 13563).
Approximately 500 metres to the north, two trenches exposed a northern extension of this fissure system. Assay results from samples taken from these two trenches were less encouraging. The best sample, MOD-83-124R, yielded 0.028 gram per tonne gold and 0.27 gram per tonne silver (Assessment Report 13563).
The area was explored in the early 1900s, resulting in the Jim Crow (Lot 1951), Bluejay (Lot 1958), Molson (Lot 2526) and Atlantic (Lot 2526) Crown-granted claims being staked. Early work consisted of prospecting and development of several opencuts and trenches. The ground covering the Rice B occurrence was explored by Riocanex in the 1970s and then by Rex Silver Mines Ltd in 1982 and 1983. Property exploration in 1992, consisting of soil geochemical sampling, was conducted by Rock Creek Resource Ltd. under the direction of M. Pardek. The most recent exploration has been conducted by the Rock Creek Joint Venture, consisting of a partnership between Phoenix Gold Resources Ltd., Gold City Mining Corp. and Orion International Minerals Corp.
Property exploration in 1991 by Rock Creek Resources Ltd. under the ownership of M. Pardek revealed two soil geochemical anomalies to the immediate northeast of the Rice B occurrence. The first was a 300 by 500 metre gold-zinc anomaly and the second was a small copper-gold anomaly (Assessment Report 22337).
During 2008 through 2012, Grizzly Discoveries Inc. completed programs of geochemical (rock, stream sediment and soil) sampling, geological mapping and airborne and ground geophysical surveys on the Dayton-Sidley area of the Greenwood Property. In 2010, a sample (10CGP177) taken north of the Rice B occurrence assayed 4.66 grams per tonne gold (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project).
