The Simlock Creek showing is located east of Simlock Creek, approximately 1100 metres above where it empties into Harveys Creek and at the north end of Cariboo Lake, 31 kilometres northeast of Likely. Access to the property is from Likely along the Cariboo River and Keithley Creek roads, then the Harveys Creek forest service road (also known as the 9600 road).

The region is underlain by (?)Hadrynian to Paleozoic Snowshoe Group rocks, which occur within the Barkerville terrane of south-central British Columbia. These metasedimentary rocks consist primarily of marble, quartzite and phyllite, which in the area of the showing comprise the Downey succession (informal name). Metamorphism of the region varies from chlorite grade to sillimanite and higher. The lode gold deposits of the region occur in rocks metamorphosed no higher than greenschist facies.

Locally, small ptygmatic quartz-carbonate veins, up to 30 centimetres wide, containing galena and sphalerite within light- grey marble and/or a limy laminated phyllite.

In 1989, a sample (29657) of massive galena from a trench assayed 1.04 grams per tonne gold (Assessment Report 19426). In a different trench, 30 metres to the east, pyrite and minor galena occur as disseminations near the contacts of a 60 centimetre thick metasiltstone bed within marble. A sample of pyrite mineralization from this occurrence yielded 7.52 grams per tonne gold (Assessment Report 19426, sample 249668).

In 1990, a sample (80028) assayed 0.11 gram per tonne gold, 19.3 grams per tonne silver, 1.20 per cent lead and 13.50 per cent zinc (Assessment Report 21310).

In 1987, a geochemical program, consisting of heavy sediment sampling using a one and a half inch suction dredge, was carried out on the Harveys Creek and Simlock Creek drainages. The geochemical program returned anomalous gold values from the Simlock Creek drainage and follow-up prospecting was recommended. In 1988 and 1989, the Simlock Creek property was optioned to Logan Mines Ltd. who carried out a program of geochemical soil sampling, ground magnetic surveying, trenching and prospecting. A total of 1175 soil samples were taken at 100 metre line and 20 metre station spacings on a grid straddling the Simlock Creek drainage. A ground magnetic survey was conducted over the same grid, totalling 18.6 line-kilometres. The geochemical sampling program detected significant gold, silver, lead and zinc anomalies. Prospecting follow up on gold geochemical anomalies immediately east of Simlock Creek uncovered an area of limestone mineralized with lead (galena), silver and gold. In 1990, a limited amount of fieldwork was carried out in a localized area surrounding the location of a 1989 soil sample that contained 4500 parts per billion gold. In 1991, a terrain analysis of the Simlock Creek property was carried out by J.M. Ryder. In 1992, Noranda Exploration Co. Ltd., as part of their examination of the Simlock Creek property, collected 46 soil samples over a grid line previously sampled in 1988. In 1993, further geochemical soil sampling was conducted on the Simlock Creek property; a total of 126 soil samples were taken on an extension of the 1988-89 grid. In 1994, the property was under option to Northern Dynasty Explorations Ltd. In 1995, Northern Dynasty Explorations Ltd. carried out geochemical soil sampling on a grid located to the southeast of the existing (1988-89) grid and completed some limited trenching. In 1997, Harvey Creek Gold Placers Ltd. constructed 627 metres of new access road on the Simlock Creek property to the south border of the 1988-89 sampling grid. The purpose of this access road was to provide access to gold geochemical anomalies detected on the 1993 sampling grid to the southeast. In 1998, Harvey Creek Gold Placers extended the access road into the 1993 sampling grid. The purpose of this road building was to access areas of anomalous gold-in-soil at higher elevations where thinner overburden could be expected. This road building and limited trenching program was successful in exposing several gold, silver, lead and zinc- mineralized quartz structures, including a significant exposure located 10 metres upslope from a geochemical soil station that had assayed 2932 parts per billion gold. In 2001, the Simlock Creek property was optioned to Extant Investments lnc. (now named Sydney Resource Corporation). In 2004, Sydney Resource Corporation took a total of 286 soil samples and 50 rock samples and completed 1.7 kilometres of ground magnetic survey. During 2009 through 2012, Barker Minerals completed programs of prospecting and soil and rock sampling on the area as the SL claims.
