Gold distribution has been incompletely examined in the BIF. BIF within the Copper Mountain district crops out as four, comparatively steady, slender beds along an 8-mile strike. BIF in the Seminoe Mountains greenstone belt forms a big useful resource within the Bradley Peak thrust sheet (Blackstone, 1965). The iron formation is intercalated in metasediments, follows schistosity in metabasalt and metagabbro, and occurs as interflow sediments between basaltic komatiite flows. In the Hartville uplift of southeastern Wyoming, giant assets of hematite schist occur in a eugeoclinal belt of Archean (?) age. Copper-silver-zinc redbed mineralizaton is widespread within the thrust belt of western Wyoming (Hausel and Harris, 1983). Many of these deposits and occurrences lie alongside the contact of the Nugget Sandstone (Triassic-Jurassic) and the overlying Gypsum Spring Member (Jurassic) of the Twin Creek Limestone (Boberg, 1986) Some deposits present proof of both structural and stratigraphic management. Might Ray E. Harris, Robert, and Richard Jones RIP and in the future obtain accountability. Hausel, W.D., and Harris, R.E., 1983, Metallogeny of some Wyoming deposits: Colorado Mining Association 1983 Mining Yearbook, p.46-63. The supply of the garnets remains unidentified and suggests that someone, someday, may discover many diamond treasures within the hills of Colorado and Wyoming.

These embrace (1) garnet (hydrogrossular), epidote, actinolite, chlorite, idocrase(?), calcite, limonite, (±) magnetite hornfels, (2) epidote, pyrite, calcite, quartz hornfels, (3) magnetite hornfels, (4) calcite, epidote, actinolite, pyrite, magnetite marble, (5) actinolite, calcite, quartz, chlorite, (±) chalcopyrite hornfels, (6) tremolite, calcite, quartz marble, and (7) uvarovite-magnetite-calcite hornfels.
In the Bald Mountain district of the Bighorn Mountains, low-grade gold and monazite paleoplacers form relatively giant resources. Just a few years ago, while looking for diamonds in California, I recovered several lovely mild-blue benitoite gemstones from panned concentrates taken within the Sierra Nevada Mountains. In the same region, a 42-ounce nugget was found in Nolan Creek in 1994. The Gaines Nugget (122 troy ounces) was found within the Kuskokwim of southwestern Alaska near McGrath. Not lengthy after the North Carolina discoveries, gold was found in Georgia. After they discovered gold in their pans, they beginning wanting up slope for lodes filled with gold. Harrer (1966) indicated the north slope of Bradley Peak comprises a resource of one hundred million tons. The geology of the world (Colorado-Wyoming State Line district) signifies a whole bunch of 1000's of tons of diamond-bearing kimberlite eroded up to now. Ore shipped from the district between 1914 and 1920, and ore recovered from the mine in 1942 averaged 3.5% Cu and 254 ppm Ag (Allen, 1942). Samples collected by Love and Antweiler (1973) contained 180 ppm 6.7% Cu, a trace to 0.5% Pb, 26 ppm 3.2% Zn, and a hint to 1,200 ppm Ag. The shears and veins comprise hint gold with sporadic ore shoots enriched in gold (Hausel, 1987). Where recognized, fold closures, shear-fault, and shear-shear intersections seem to localize some ore shoots.
