The Bob occurrence is located at an elevation of approximately 1570 metres, in the north headwaters of Rusy Creek and approximately 1.3 kilometres southeast of the south end of Roscoe Lake.

The area is situated on the southeastern flank of the Upper Triassic to Lower Jurassic Guichon Creek Batholith in an area primarily underlain by Skeena variety granodiorite. Approximately 1500 metres to the west of the Bob showing, the Skeena rocks are in contact with the younger Bethsaida phase, which consists of quartz monzonite to granodiorite and slightly younger porphyry dikes and plugs. The contact is characterized by a broad zone of moderate to extreme propylitic alteration and fracturing.

On the Bob 6 claim, the Skeena granodiorite is intruded by a 75-metre wide Bethsaida dike trending 015 degrees. Drillhole results (1965) indicate the dike is moderately altered and fractured with extensive limonitic staining. Widespread sparse amounts of malachite, pyrite and chalcopyrite are exposed near the surface. At depth the altered rocks are mineralized with disseminations and fracture-fillings of hematite, minor bornite, secondary chalcocite and molybdenite.

On the Bob 2 claim, to the south of the Bob 6 claim, diamond drilling (1972) has identified a chlorite-sericite–altered Skeena granodiorite hosting a shear zone with malachite. Minor chalcopyrite and pyrite are also reported. Drilling yielded up to 0.30 per cent copper over 3.0 metres in hole M72-4 (Assessment Report 4050).

Work History

In 1964, Chataway Exploration Co. Ltd. completed a 5.0 line-kilometre ground electromagnetic survey and a 16.7 line-kilometre induced polarization survey on the area as the Rob, Ros, Rum and Tom claims of the Chataway property.

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., Moon and Wiz-Dot claims of the Chataway property.

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 1979, Lawrence Mining Corp. completed a 102.8 line-kilometre induced polarization survey on the 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 immediately west of the occurrence as the CVS property.

In 2004 and 2005, Happy Creek Minerals completed program of geological and GPS surveying and minor stream sediment sampling on the Rateria property. Later in 2005, a program of two diamond drillholes (totalling 341 metres), 13.5 kilometres of cut line and induced polarization survey, prospecting, geological mapping, and 20 rock samples (10 assayed) was conducted on the property. In 2006, a further 14 diamond drill holes, totalling 2400.0 metres, were completed on the property. In 2007, Happy Creek Minerals Ltd. completed a program of diamond drilling, totalling 3082 metres, in 14 holes on the Rateria 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-interpretation of historical airborne geophysical data on the area as part of the Rateria-West Valley property.
