The Big-C target occurs 15.0 kilometres south of Kaslo, on a ridge separating Woodbury and Lendrum Creeks. The area was staked in 2006 by Goldcliff Resource Corporation as part of its Ainsworth Silver Project. In 2007 a multi-sensor airborne geophysical survey and follow-up geochemical sampling identified the anomalous target area.

Regionally, the area is underlain by Mississippian to Lower Permian Milford Group limestone and is in contact with the Permian Kaslo Group greenstone.

Locally, the Big-C showing is completely covered by overburden, but covers an area of 700 metres in length and 500 metres in width, trending north along the Mississippian Milford limestone and Permian Kaslo greenstone interface. The target is associated with a regional fault and contains cross structures. The target has individual conductors that strike north-northwest and vary in length from 50 to 500 metres.

The Big-C target has a strong silver soil anomaly with exploration indicator elements that coincide with the north-northwest structural trends. Silver values range from 1.02 to 2.92 grams per tonne. Exploration indicator elements were anomalous in arsenic to 56.3 parts per million, cadmium to 5.19 parts per million, cobalt to 1345 parts per million, copper to 372 parts per million, iron to 36.28 per cent, lead to 539 parts per million, molybdenum to 16 parts per million, nickel to 361 parts per million and zinc to 466 parts per million (http://www.goldcliff.com/index.php).
