The Choc 2 showing is located on a ridge separating Behrman and Slipper creeks, approximately 5.5 kilometres north east of the Duncan Lake Quartzite (MINFILE 082KSE062) quarry. The Choc and Choc 2 claims were staked in July, 2000 and a program of geological mapping was performed the next year.

Locally, quartz sericite schists of the Upper Proterozoic Horsethief Creek Group occur. The micas vary from sericite to phlogopite to biotite and vary from 5 per cent to locally 90 per cent. The schist is banded with bands of fine- grained quartzite interspersed with bands of near massive mica. The banding varies from a few millimetres to several metres.

The rocks of interest are two-fold. Firstly, the finely banded rock cleaves into platy slabs, which may be useful as a building stone. Secondly, there are massive sections with very sparse jointing, which may be suitable for dimension stone cutting.
