|Location and accuracy||This occurrence is the site of sample 3MZ0007b, plate 1, of U.S. Geological Survey, Open-File Report 84-479 (Foster and others, 1984). It is approximately 1 mile southwest of VABM 3125, about 5 miles southwest of Circle Hot Springs, near the northeast corner of section 18, T. 7 N., R. 14 E. The location is accurate.|
Geologic descriptionA 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).
