The centre of the Frank Creek property is situated 95 kilometres northeast of Williams Lake and 34 kilometres northeast of Likely. Access to the Ace, Frank Creek and SCR exploration areas is via gravel logging roads bearing northeast from Likely. In Likely, Barker Minerals Ltd. maintains a property that includes a house, a bunkhouse, a workshop and a few tents. The house serves as a field office.

In June 1999, Barker Minerals Ltd. discovered sulphide float in a roadcut. Trenching exposed a bed of massive sulphide mineralization in excess of 1.2 metres thick. It is composed mainly of fine-grained pyrite with local disseminations and wispy bands of chalcopyrite, pale-brown sphalerite and galena. Fractures and a foliation-parallel fabric contain coarser grained base metal sulphides with silica ± chlorite. Enclosing rocks are an overturned package of phyllitic argillites, reworked felsic pyroclastics and pillow basalts mapped as part of the Paleozoic Snowshoe Group (Harveys Ridge succession). A 1.2-metre (true width) channel sample assayed 0.65 per cent copper, 0.14 gram per tonne gold, 69 grams per tonne silver, 0.12 per cent lead and 0.10 per cent zinc. In addition to the main bed, numerous small lenses of massive sulphide, up to 10 centimetres thick, were noted (Exploration in British Columbia 1999, page 23).

In the discovery trench and 2002 drillholes, the main rock types are graphitic argillites, sandstones, siltstones and local quartz-pebble sandstones belonging to the Harveys Ridge successions of the Snowshoe Group. In the discovery trench and drillhole FC-02-03, these lithologies host up to 0.3-metre thick beds of massive sulphide. In the float above the discovery trench, blocks contain massive sulphide beds that are at least 0.5 metre thick. Alteration zones in drillholes FC-02-05 and FC-02-06 contain intervals (on the scale of metres) of disseminated sulphides and up to 0.7-metre sections of semi-massive sulphides. Grab samples from the area contained anomalous results for copper, lead, zinc, arsenic, antimony, bismuth, tin and silver.

Drillhole FC-02-03 intersected 0.5 metre of 0.52 per cent copper, 0.28 per cent lead, 0.33 per cent zinc and 89.0 grams per tonne (2.6 ounces per ton) silver, and drillhole FC-02-06 intersected 0.45 metre of 2.08 per cent copper, 0.54 per cent lead, 0.98 per cent zinc and 89.0 grams per tonne (2.6 ounces per ton silver; Assessment Report 27655, page 14)

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 and SCR (MINFILE 093A 203) target areas. In 2002, Barker Minerals conducted trenching and drilling on its Frank Creek prospect, located immediately south of Cariboo Lake. A total of 1459.1 metres of drilling in 11 holes on the Frank Creek and Ace occurrences was completed in August 2002 (Press Release Barker Minerals Ltd., August 27, 2002). At the Frank Creek occurrence, six holes totalling 813.21 metres were completed and 70 core samples were collected and sent for analysis. All six drillholes were within 300 metres of the Frank Creek occurrence and four of the six drillholes tested the Frank Creek mineralized horizon. Drillholes FC-02-01, FC-02-05 and FC-02-06 intersected dominantly pyritic disseminated to semi-massive sulphides near the projected location of the mineralized horizon. Drillhole FC-02-03 intersected 50 centimetres of pyritic massive sulphide in a large, gougy fault zone. Five trenches totalling 289 metres were excavated in the immediate vicinity of the Frank Creek occurrence. Horizontal loop electromagnetic (HLEM), gravity, very low frequency electromagnetic (VLF-EM), and induced polarization (IP) geophysical surveying were carried out around the Frank Creek occurrence that year. Six rock samples were also collected from an area immediately to the southwest of Frank Creek.

In 2003, Barker conducted trenching, geological mapping and geochemical sampling programs on its Ace, Frank Creek, SCR and Rollie Creek (MINFILE 093A 163) volcanogenic massive sulphide (VMS) prospects. That year, six rock samples were collected from the Frank Creek occurrence. In 2004, 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.

During 2004, the company conducted an exploratory diamond drilling program consisting of 7 diamond drill holes, totalling 1880 metres, on grid line 59 north and 21 west, in the vicinity of the copper-rich sulphide outcrop discovered that year and near geological and geophysical targets. All of the 2004 drillholes were located around the F-7 target area (093A 152, located approximately 1400 metres due south of the mouth of Frank Creek in Cariboo Lake) and were focused on Titan geophysical targets or bedrock mineralization.

Surface grab samples were taken from sub-outcrop to outcrop material in the F-7 area. The high-grade polymetallic nature of this bedrock mineralization is consistent with a Besshi or Sedex-type copper-zinc massive sulphide deposit. Fifteen grab samples were collected by Barker personnel from an approximately 10 by 20-metre area of variably mineralized material. The significant initial assay results included up to 21.2 per cent copper, 0.73 per cent lead, 8.44 per cent zinc and 165 grams per tonne silver (Assessment Report 27655). The mineralization occurs as disseminations, blebs, stringers and semi-massive to massive sulphide lenses in a heavily altered sedimentary hostrock. Sulphides present include pyrite, sphalerite and abundant chalcopyrite.

In 2005, Barker Minerals Ltd. continued exploration work, which 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. Grab samples from trench FC07-3 yielded values of up to 1.80 per cent lead, 3.19 per cent zinc and 1.58 per cent copper (Turna, R. (2008-03-29): Technical Report on Frank Creek Property, SCR and Peacock (Rollie Creek) Prospects).

In 2008, Barker Minerals Ltd. completed a 13-hole drill program totalling 2375 metres.

In 2009, Barker Minerals Ltd. conducted an exploration program of rock sampling, trenching and diamond drilling. Highlights of the drilling include drillhole FC09-38, which assayed 0.40 metres grading 1.06 per cent lead and 8.7 grams per tonne silver (Assessment Report 31389).

In 2011, Barker Minerals Ltd. drilled eight holes, totalling 422.02 metres, at Frank Creek. Highlights include drillhole FC11-03, which assayed 22.45 metres grading 3.8 grams per tonne gold (Press Release, Barker Minerals Ltd., April 13, 2012).

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 contained a highly anomalous gold value, assaying 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).
