Feb 07, 2018 (Therese Pettigrew) - Scripture's vein occurs on mining location R 61 on the east-facing cliff of Silver Bluff, 1.5 miles southeast of Silver Mountain station. The vein has been stripped for a vertical distance of 25 feet on the upper part of the cliff. It is naturally exposed for 20 feet below on a sheer part of the cliff and 75 feet below this there is an adit, the mouth of which has caved. From the amount of material exposed on the dump it appears probable that the adit is not more than 25 feet long. The vein is from 2 to 3 feet wide, and a few parallel stringers up to 2 inches in width occur within 2 feet of the walls of the main vein. It trends north 75 degrees west and dips 85 degrees toward the north. The vein consists of coarsely crystalline white calcite and barite, with green fluorite in discontinuous bands an inch or two in width along the walls. In the central part of the vein there are irregular developments and vug linings of white and amethystine quartz with well-terminated crystals. Throughout the greater part of the vein the coarsely crystalline barite is the most abundant mineral constituent. The upper 25 feet of the vein, as exposed, is in diabase, the lower part is in grey taconite, the beds dipping 2 degrees towards the southwest. The contact between the sediments and the overlying diabase sill occurs on a sheer cliff and the amount of dislocation along the fissure occupied by the vein is apparently about 4 feet. There is a notch on the side of the diabase cliff and a drift-covered valley extends from it north 75 degrees west on the top of the hill (Tanton, 1931).
