The Sand Creek occurrence is located about 20 kilometres west-southwest of the town of Williams Lake and just west of Mosely Creek.

The occurrence lies within diverse intrusive rocks of the Klinaklini pluton of the Jurassic to Tertiary Coast Plutonic Complex (Geological Survey of Canada Open File 1163). The main granodiorite pluton has been assigned to the Late Cretaceous to Paleocene Bendor suite. Small granodiorite stocks underlying the VB, A & E and PW prospects are assigned to the Eocene Mission Ridge suite.

A single instance of bedrock molybdenite mineralization was reported in 1979 within the Sand Creek valley at 1630 metres elevation (Assessment Report 8115). A northwest trending fault is mapped at this location. This occurrence is documented as being near the westernmost limit of recorded exploration work within Sand Creek drainage until 2009 when minor sampling and prospecting, from 1 to 3 kilometres further downstream, was conducted (Assessment Reports 31946 and 33519). A northwest trending fault is mapped at this area.

WORK HISTORY

In 1979, the Esperanza Explorations Ltd. staked the Sand property. A prospecting program confirmed the presence of low-grade mineralization at the A & E (092N 032) and VB (092N 013) prospects (Assessment Report 8115). This survey also identified molybdenum mineralization southeast of the core A & E zone, at a lower elevation within the upper Sand Creek drainage.

In 2010, Paul Hoogendoorn and Peter Palikot completed work on their Walrus property in the Sand Creek valley. The Walrus Property can be viewed as comprising two different but contiguous zones: (1) the “A & E” zone (092N 032), a previously explored molybdenum – copper plutonic porphyry prospect, and (2) the previously unexplored “Walrus South” zone. Work on the South Walrus zone consisted of consisted of geological surveying and geochemical rock sampling in the lower and middle portions of the 'Sand Creek' drainage (Assessment Report 31946). In total, 5 bedrock, 3 float, and 1 stream sediment samples were obtained across an area of approximately 30,000 square metres.

No historical industry mapping is recorded on the Walrus South ground explored in 2010; however, authors of 2010 work reported that their observations were generally consistent with proximal lithologies identified by past workers on the A & E prospect (granodiorite and quartz monzonite).

The 2012 work program of Paul Hoogendoorn and Peter Palikot consisted of the collection of 8 stream silt samples at 7 station sites along and within the central portion of Sand Creek between the 1417 and 1333 metres elevation, over about 560 metres. They collected 8 stream silt samples from 8 small, unnamed tributaries of Sand Creek, in the northern half of the Sand Creek drainage. These tributary streams drain a gossaneous ridge rising to approximately 1 kilometre (local relief) and running approximately 1.5 kilometres eastward from the VB Zone. Silt sample results indicated enrichment to 151 parts per million copper and 18 part per million molybdenum. Two “anomalous” gold results were reported 8 parts per billion and 10 parts per billion (Assessment Report 33519). No outcrop was located, nor was molybdenite-bearing float observed.

See VB (092N 013) for related geological and work history details.
