The Ket 28 occurrence is located at 1220 metres elevation, 4 kilometres east-southeast of Bridesville, British Columbia.
The oldest rocks in vicinity of the Ket 28 occurrence belong to the Permian to Carboniferous Kobau and Anarchist groups. Amphibolite, greenstone, quartzite, chert, chlorite schist and minor marble comprise the Kobau Group and amphibolite, greenstone, quartz chlorite schist, quartz biotite schist and minor serpentinized peridotite comprise lithologies of the Anarchist Group. Penticton Group lithologies outcrop to the east while Middle Jurassic porphyritic granite, granodiorite and monzonite intrusions are found to the immediate north. Smaller plugs, dikes and sills of biotite granodiorite, quartz diorite and granite of Middle Jurassic to Cretaceous age intrude the Anarchist Group rocks.
Tight folds are noted along northeast and north-trending faults in Anarchist and Kobau groups metasediments and metavolcanics. Phyllitic and mylonitic fabrics along with minor breccia zones occur adjacent to most predominant fault structures.
The RM mineral claim group is underlain by the Anarchist Group. At the Ket 28 occurrence, chlorite schist striking northwest with mylonitic textures is the predominant rock type. Propylitic alteration is common. The Ket 28 occurrence occurs along strike of the 18 kilometre long, northwest striking Rock Creek fault zone hosting identifiable gold-bearing anomalies over 300 metres strike length and 50 metres width.
Gold mineralization at the Ket 28 occurrence is hosted in discontinuous pods of pyrite bearing, matrix supported, brecciated quartz veins and sweats, along the southern extension of the Rock Creek fault zone.
In 1990, property exploration by Crownex Resources (Canada) Ltd. consisted of geochemical soil sampling, rock chip sampling, a ground magnetic geophysical survey and seven reverse circulation-drill holes.
Rock chip samples of old trenches, pits and adits yielded anomalous gold values that correlate well with quartz veins in argillically altered chlorite schist in close proximity to siliceous magnesite skarn (Assessment Report 21413). The highest gold value was returned from sample 90CM-243-R, which yielded 2.47 grams per tonne gold and 0.60 gram per tonne silver (Assessment Report 21413). This chip sample consisted of siliceous magnesite with pyrite. Sample 90CM-262-R yielded 3.870 grams per tonne gold and 2.0 grams per tonne silver (Assessment Report 21413). Sample 90CM-455-R, a sample of pyritic argillite with trace magnesite, yielded 2.12 grams per tonne gold (Assessment Report 21413).
These results lead to the discovery of a soil geochemistry anomaly. Follow-up ground magnetic geophysical survey results indicated an anomaly in the vicinity of the soil geochemistry gold anomaly. These anomalies occur in a broad argillite-phyllite belt near diorite outcrop and locally mylonitic magnetite-bearing greenstone.
This was followed by seven reverse circulation percussion-drill holes with over 658 metres drilled total, targeted on discontinuous pyrite, siderite and quartz sweated veins within a north trending phyllonitic to mylonitic zone. Reverse circulation percussion-drill hole KT-1 yielded 6.1 metres grading 8.91 grams per tonne gold (Assessment Report 21413). Pyrite, hematite and magnesite with silicification and bleaching in greenstone and diorite are all associated with anomalous gold values. Magnetite is locally abundant above anomalous gold mineralization with pyrrhotite dominating near diorite.
During diamond drilling in 1994, diamond-drill hole 94-RM1-2C intersected 3.35 metres with a weighted average of 52.22 grams per tonne gold (George Cross News Letter No. 115 - June 16, 1994). Assay samples from diamond-drillholes 94-RM1-1C and 94-RM1-3C also yielded significant gold values (George Cross News Letter No. 115 - June 16, 1994).
Further aggressive property exploration up to 1996 included diamond drilling, electromagnetic and induced polarization geophysical surveys and limited rock chip geochemical sampling. The best drillhole results from 1996 were from diamond-drill hole 96GH-17C which yielded 3.77 grams per tonne gold over the 4.3 metre interval from 70.7 to 75.0 metres depth Property File - Phoenix Gold Resources Ltd. (1996): News Release). These results are related to pervasively silicified volcanic breccia. Observations in 1996 indicated the oxidized upper part of the structure are low and erratic. Deeper in the structure, gold values are higher, more consistent and appear to have associated pyritization, silicification, and an increase in felsic dikes (Property File - Gold City Mining Corp., Orion International Mineral Corp., Phoenix Gold Resources Ltd. (1996): Joint News Release).
During 2008 through 2012, Grizzly Discoveries Inc. completed programs of geochemical (rock and soil) sampling, ground geophysical surveys and 12 diamond drill holes on the Ket 28 area of the Greenwood Property.
In 2009 and 2010, diamond drilling yielded intercepts including 2.77 and 8.75 grams per tonne gold over 11 and 3 metres in holes 9KT01 and 9KT02, respectively, while rock samples (09BMP095) yielded up to 53.20 grams per tonne gold and 15.7 grams per tonne silver (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project). The mineralized zone is reported to be open to depth and along strike.
