The SCR volcanogenic massive sulphide prospect was discovered by Barker Minerals Ltd. in 2000 on its Frank Creek property. It is located approximately 2 kilometres south of Cariboo Lake and 25 kilometres northeast of Likely. Work on the property is limited to reconnaissance mapping, some sampling and a soil geochemical survey.
The SCR was identified by the discovery of semi-massive sulphide and stringer sulphide mineralization in float and bedrock within altered intermediate to mafic volcanic rock of the Paleozoic Snowshoe Group. Sulphide minerals include pyrite, pyrrhotite, chalcopyrite, sphalerite and galena. Geophysical surveys successfully outlined significant, coincident magnetic and conductive anomalies (HLEM) near the discovery area and near the area of Cu, Pb and Zn soil anomalies.
Barker Minerals Ltd. began exploration programs in the area in 1999. Most of their early efforts focused on the Frank Creek showings (MINFILE 093A 152, 093A 231) to the east on the south side of Cariboo Lake. In 2000, the company completed 140 line-kilometres of line cutting and horizontal loop electromagnetic (HLEM) and magnetic surveys over the Ace (MINFILE 093A 142), Frank Creek (MINFILE 093A 152) and SCR target areas. Rock samples (2115) of outcrops and boulders hosting semi-massive sulphide mineralization in silicified intermediate volcanics yielded up to 0.17 gram per tonne gold, 0.19 per cent copper, 6.40 per cent lead and 17.30 per cent zinc (Turna, R. (2008-03-29): Technical Report on Frank Creek Property, SCR and Peacock (Rollie Creek) Prospects).
In 2002, Barker Minerals collected 11 soil and 19 rock samples from the SCR occurrence. That same year, Barker Minerals conducted trenching and drilling on its Frank Creek (VMS; MINFILE 093A 152) prospect, located northeast of the SCR occurrence and immediately south of Cariboo Lake.
In 2003, Barker conducted modest trenching, geological mapping and geochemical sampling programs on its Ace, Frank Creek, SCR and Rollie Creek (VMS; MINFILE 093A 232) prospects. Sampling of trenches yielded up to 4.5 grams per tonne silver, 0.119 per cent copper, 0.313 per cent lead and 0.495 per cent zinc (Turna, R. (2008-03-29): Technical Report on Frank Creek Property, SCR and Peacock (Rollie Creek) Prospects).
In 2004, the SCR, Peacock (MINFILE 093A 133), and Unlikely (MINFILE 093A 163) showings were briefly examined as part of Barker Minerals Ltd.’s Frank Creek exploration program. That year, Barker Minerals conducted a “Titan” geophysical survey over part of its Frank Creek (VMS) prospect. Results from this survey, coupled with information from earlier surveys by the company, provided trenching and drilling targets that were tested late in 2004. Trenching exposed a zone of polymetallic, base metal sulphide mineralization in stringers and semi-massive bands within metasedimentary rocks of the Paleozoic Snowshoe Group. The company also discovered stringer and semi-massive to massive sulphide showings on its SCR and Rollie Creek prospects.
In 2005, Barker Minerals Ltd. continued exploration work on the Frank Creek property. The program consisted of four diamond drill holes, totalling 1565 metres, and ongoing interpretation of the lithogeochemistry. In the spring of 2006, an additional five drillholes were completed totalling 2037.10 metres. During the winter of 2006, Barker Minerals Ltd. drilled two follow-up NQ drillholes, totalling 705 metres, and collected 98 core samples. That same year, enzyme leach soil sampling was used to outline anomalous geochemical trends. In 2007, trenching exposed several lenses of semi-massive to massive sulphides including sphalerite, galena, chalcopyrite and pyrite occurring in hydrothermally altered and regionally metamorphosed rhyolitic volcanics. Excavations consisted of five trenches, totalling 250 metres, and 24 test pits. In total, 138 rock samples and 800 soil samples were collected.
In 2008, Barker Minerals Ltd. completed a 13-hole drill program on the Frank Creek occurrence (MINFILE 093A 152, 093A 267), totalling 2375 metres.
In 2009, Barker Minerals Ltd. conducted an exploration program of rock sampling, trenching and diamond drilling. In 2011, Barker Minerals Ltd. drilled eight holes, totalling 422.02 metres, at Frank Creek.
In 2016, Barker Minerals Ltd. conducted a rock sampling program on the Frank Creek property. In total, 136 rock samples were collected from surface float. Zinc, copper and lead anomalies occurred in argillites and sandstones. Sample 286 reported a highly anomalous gold value with 501.2 grams per tonne gold (Assessment Report 36449). The next highest grading sample, sample 289, assayed 14.63 grams per tonne gold, 0.025 per cent copper and 0.058 per cent zinc (Assessment Report 36449).
