|Location and accuracy||The Spring antimony occurrence is in upper Rocky Mountain Creek, an east tributary to upper Nome River, at an elevation of 1,150 feet. It is locality 17 of Hummel (1962 [MF 248]) and included in locality 32 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The prospect is located within about 1,000 feet of the coordinates.|
Geologic descriptionHummel (1962 [MF 248]) identified the Spring prospect as an antimony occurrence. The ore mineral is assumed to be stibnite, possibly with quartz and some gold values, that occurs in veins that cross-cut the metasedimentary rocks. The prospect is in, or stratigraphically above, a massive marble intercalated in metasedimentary schist (Hummel, 1962 [MF 248]).
