Location and accuracy The occurrence is on the ridge north of Dahl Creek (not shown on the 1972 edition of the USGS topographic map), about 2.8 miles northeast of Mount Distin. Dahl Creek is a west-flowing upper tributary of Lost Creek, a south tributary of Stewart River. The occurrence is at an elevation of about 1,450 feet and about 1,000 feet north of the Hed & [and] Strand antimony mine (NM070); it is included within the claim block of the Bulk Gold prospect (NM071). It is locality 30 of Hummel (1962 [MF 248]), and possibly locality 45 of Hummel (1975). This occurrence is probably located within about 1,000 feet of the coordinates.

Geologic setting

Geologic description

Hummel (1962 [MF 248]) identified this locality as an antimony occurrence. It appears to be near locality 45 of Hummel (1975), which is shown as a sulfide-bearing silicified marble. The occurrence is assumed to contain stibnite and possibly red and yellow secondary oxide minerals of antimony. It is one of numerous occurrences of antimony in the area, most of which contain at least a small amount of gold.
The area near the occurrence has been mapped by Hummel (1962 [MF 248]) and by Bundtzen and others (1994). The two maps show appreciably different geology, and the differences cannot be reconciled without additional field work. In general, the rocks exposed near the occurrence are the so called mixed unit of Bundtzen and others (1994), including massive marble and feldspathic epidote schist. Hummel (1962 [MF 248]) mapped a strong, north-northeast-striking fault about 1,000 feet west of the occurrence and another, less certain, northeast-striking fault essentially at the occurrence.
