Report: Hidden Vein LC001531 This occurrence is located up Lyons Creek on the Rogers Pass quadrangle in section 32, T.15N., R.5W. Workings at this site consist of a single shallow trench approximately 100' long (USBM file 21.061). This site was screened out due to the limited extent of the reported workings and the low-grade nature of the ore (a sample taken by the U.S.B.M. ran 0.005 opt Au, 0.6 opt Ag and 2.18% Cu). The mineralization occurs near the contact between Precambrian Spokane formation and diorite. Ore and gangue minerals reportedly are: bornite, quartz, epidote, siderite and carbonates.
