The Sho showing is located on Twin Dot Creek, west of Broom Creek and approximately 3.5 kilometres south of the south end of Chataway Lake.
The area is situated in the southeastern portion of the Upper Triassic to Lower Jurassic Guichon Creek Batholith underlain primarily by Chataway variety granodiorite of the Highland Valley phase, the oldest phase of the intrusion. The coarse-grained granodiorite is intruded by north-northeast-trending granodiorite and porphyry dikes (up to 150 metres wide) and plugs belonging to the Bethlehem phase (EMPR PRELIM Map 30). The Guichon Creek Batholith is cut by north- and west-trending regional faults.
Mineralization and alteration on the Sho 11 showing are structurally controlled. Heavy malachite lenses in a white sericite gouge occur along narrow northwest-trending shears. Alteration consists of extensive kaolinite, sericite and chlorite, with minor limonite and hematite staining. Malachite is observed over an area 183 by 76 metres. Bulldozer cuts and drillholes have intersected narrow sections of erratic malachite and chalcocite mineralization in sericitized and chloritized Chataway granodiorite.
In 1963, drilling is reported to have intercepted massive chalcocite yielding 0.75 per cent copper over 3.6 metres and 0.9 per cent copper over 1.2 metres from the northernmost hole, whereas the southernmost hole yielded 4.53 per cent copper and 99.2 grams per tonne silver over 0.6 metre (Property File 10409). Core recovery for these sections was reported to be poor.
Drilling in 1967, is reported to have yielded values of up to 5.4 per cent copper over 3.0 metres within a 6-metre wide shear zone (Assessment Report 22373).
In 1992, a grab sample from a historical trench yielded greater than 1.0 per cent copper (Assessment Report 22373).
In 2014, a rock sample (FIR14-A01) of phengitic muscovite and malachite from a historial trench yielded 3.23 per cent copper, 23 grams per tonne silver and 0.260 gram per tonne gold (Assessment Report 35321).
Work History
During the 1960s, Chataway Exploration completed programs of geological mapping, geochemical sampling, drilling and ground geophysical surveys on the area. In 1968, King Resources Co. completed a program of geological mapping on the area as the Ant, In, Jay, Len, Rex, Rob, Sho, T.D.M. and Wiz-Dot claims of the Chataway property.
During the 1970s, numerous operators including Asarco, Canadian Superior Exploration, International Mogul Mines Ltd. and Aselo Minerals completed programs of ground geophysical surveys on the area.
In 1972, International Mogul Mines Ltd. completed a program of geological mapping, a 53.0 line-kilometre induced polarization survey and four diamond drill holes, totalling 355.7 metres, on the area as Bob, Moon, Sho and Val claims of the Chataway property.
In 1981, Cominco Ltd. completed an induced polarization survey and a ground magnetic survey on the area immediately north of the occurrence as the Apollo and Nova claims.
During 1991 through 1993, Aucumo Resources and Hudson Bay Exploration completed programs of geological mapping, soil and stream sediment sampling and an induced polarization survey on the area as the CVS property.
During 2008 through 2012, Happy Creek Minerals Ltd. completed further programs of diamond drilling, geological mapping, geochemical sampling and geophysical surveys on the Rateria property.
During 2013 through 2019, Happy Creek Minerals Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, a 32.3 line-kilometre induced polarization survey and re-interpretating historical airborne geophysical data on the area as apart of the Rateria-West Valley property.
