The Bjerk-1 target occurs 7.5 kilometres south of Kaslo, on a ridge separating Bjerkness and Fletcher 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.

The Bjerk-1 target is underlain by Triassic Slocan Group rocks of argillite and limestone in juxtaposition with the Permian Kaslo Group greenstone. Locally, the target occurs in Triassic Slocan Group rocks and is a northerly trending feature some 1,200 metres in length and 600 metres in width. The target contains moderate to strong individual EM conductors that strike north to north-northwest and vary in length from 200 to 500 metres. The conductors are interpreted to be structures and are accompanied by a circular magnetic-high response interpreted to be a Cretaceous Fry Creek intrusion.

Strong silver values were identified at the intersection of a strong conductive structure and the north east Bjerk fault. Soil samples within the anomaly ranged from 1.0 to 5.2 grams per tonne silver. Exploration indicator elements returned 0.51 to 26.61 parts per million cadmium, 12.0 to 91.5 parts per million copper, 0.73 to 61.03 parts per million molybdenum, 12.0 to 91.5 parts per million lead and 12.0 to 91.5 parts per million zinc (http://www.goldcliff.com/index.php).
