The area of the Whistlepig occurrence is underlain by sedimentary strata of the Upper Triassic Stuhini Group.

The Whistlepig showing was discovered by B.C. Geological Survey personnel during a regional mapping program in 2003. A fault zone cutting Upper Triassic siltstone hosts mineralization which is exposed along a southwestern tributary of Ball Creek, two kilometres west of the Hank deposit. The fault is part of a regionally extensive zone of faults called the Northmore fault zone, which ranges up to 100 metres wide. Alteration associated with this structure was mapped by the British Columbia Geological Survey over a strike length of 2.6 kilometres at elevations between 1200 and 1500 metres, approximately. Mineralization occurs as semi-massive sulphides in fault-hosted, quartz-calcite veins. The veins were sampled in two locations, the best assay yielding 0.73 gram per tonne gold, 2.87 grams per tonne silver, and 0.1 per cent copper (Assessment Report 28076).

Mapping, sampling and drilling by Paget Resources in 2005-2011 occurred on the Ball Creek Property which encompassed the Whistlepig area. A total of 231 rock samples were collected during the 2005 program.
