MLA 9-93 - Mineral Resources Of The Secesh Study Area, Idaho And Valley Counties, Idaho

The Bureau of Mines conducted a mineral investigation of the 177,000-acre Secesh study area; most of the area had been proposed as wilderness. Bureau personnel mapped and sampled several hundred mine and prospect workings; 1,715 rock, soil, and placer samples were taken during the investigation. The study area is centered about 25 mi east-northeast of McCall, Idaho, in the Payette National Forest. Five mining districts extend into or are adjacent to the study area. There have been more than 3,000 mining claims located inside the study area, 884 are current. In excess of $17 million (historical value) in placer and lode gold has reportedly been produced from the Warren district alone. The study area contains gold, silver, copper, lead, zinc, tungsten, and antimony. At least six properties that would be in the proposed wilderness contain gold resources; more than 18 million tons averaging 0.038 oz/ton gold have been identified. Additional resources may be located at 4 other localities. The 4th of July mine is currently producing gold/silver/lead ore. Similar resources may be located on at least 3 other properties. Placer samples from the study area contained up to 0.34 oz gold/yd3 ($120/yd3). The samples are representative of relatively small occurrences and do not constitute resources; small quantities of gold may be recovered by recreational placer miners.
