Location and accuracy These are two Peterson and Lamoreaux prospects, one at 650 feet elevation and one at 550 feet elevation, on Banner Peak. This is about the same as locality 13 of Hummel (1962 [MF 247]) and locality 50 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The map location is in the SW1/4 section 35, T. 10 S., R. 34 W., Kateel River Meridian.

Geologic setting

Geologic description

Banner Peak is underlain mainly by graphitic quartz schist (quartzite) faulted to the north against chlorite-rich metaturbidite schist and marble (Bundtzen and others, 1994). The Peterson and Lamoreaux quartz prospect is at an elevation of 650 feet in graphitic schist and within about 200 feet of the fault. Mertie (1918, p. 432) reported that the quartz body had a strike of N 45 E and a dip of 45 N, and was at least 8 feet thick, and irregularly bounded. The quartz is nearly white and not banded and contains sparsely disseminated galena. The Peterson and Lamoreaux antimony prospect is at an elevation of 550 feet, but its location is uncertain. It is in schist and reportedly produced 1,500 pounds of stibnite ore (Mertie, 1918, p. 439).

Mineral deposit model Low-sulfide Au-quartz vein (Cox and Singer, 1986, model 36a); simple Sb deposits? (Cox and Singer, 1986; model 27d).
Mineral deposit model number 36a, 27d?
Age of mineralization Probably mid-Cretaceous; Mertie (1918 [B 662-I, p. 425-449]) thought the vein quartz could be old and possibly related to metamorphism; see NM207.

Production and reserves

Workings or exploration Open cuts and shallow shafts were developed before 1916.
Indication of production Undetermined
Production notes About 1,500 pounds of antimony ore reportedly were produced from the Peterson and Lamoreaux antimony deposit (Mertie, 1918 [B 662-I, p. 425-449]).
