Relative position | The Breen West mine is on the Bison Lode claim, which was patented in 1924. It is at an elevation of about 800 to 1,000 feet on the southwest-facing slope of the ridge between Cold and Manila Creeks and accessible by foot or ATV from a trail which starts in Steep Creek. It is about one-half mile southeast of an unnamed occurrence (NM088) that was mistakenly called Breen West by Hummel (1962 [MF 248]). The Breen West mine is about 1,000 feet west of the vein outcrops on the My Best Lode claim (U.S. Mineral Survey No. 1380) of the Sliscovich mine (NM086). This location is within 500 feet of the surface workings, heavy quartz-stibnite float, and the main discovery cuts on the Bison Lode claim (U.S. Mineral Survey No. 1391). This is locality 1 of Hummel (1962 [MF 248]) and locality 27 of Cobb (1972 [MF 463], 1978 [OFR 78-93]) who apparently mistakenly identified it as Breen East. |
