Geologic setting

Geologic description

A sample of quartzite with arsenopyrite contained 3.2 ppm Au and 0.5 ppm Ag (Foster and others, 1984). This prospect is probably within a large block of ground that is currently (2008) being explored by Millrock Resources Inc. (2008). The geology and past exploration within the block is discussed in the ARDF record for the '88 group' (CI001).
