EXHIBIT I SOILS INFORMATION <br /> The following resources were used in developing soils information: <br /> • Parker, Ben H., Jr., 1974, The Gold Placers of Colorado, Colorado School of Mines. <br /> • Soil Conservation Service (SCS), 1976, Range Site Description for Dry Mountain <br /> Outwash (Code 316). <br /> • Soil Conservation Service (SCS), 1976, Range Site Description for Mountain Outwash <br /> (Code 311). <br /> • U.S. Dept. of Interior(1950), Gold Placers and their Geologic Environment in <br /> Northwestern Park County, Colorado, U.S.G.S. Bulletin 955-D. <br /> • Aerial map from 1979 before mine permitting. <br /> Gold-bearing gravels located in this area are primarily glacial in origin. These gravel deposits <br /> are designated lateral and possibly terminal moraines left by the last retreating glaciers and <br /> appear to be largely unchanged by subsequent erosion actions east of the South Platte River. <br /> West of the South Platte River,where stream action and man destroyed the distinctive structures <br /> of these glacial gravel deposits, sands in the Alma mining district are largely granitic gneisses <br /> with a small percentage of sedimentary, volcanic and metamorphic materials. The sizing of <br /> gravels is estimated in Table I-1. <br /> TABLE I-1 Sizing Estimates of Gravels on the Alma Group Claims <br /> Plus 24 inch rocks, few above 36 inches 10% <br /> Plus 6 inch rocks minus 24 inch rocks 10% <br /> Plus 2 inch rocks minus 6 inch rocks 30% <br /> Sands minus 2 inch rocks 40% <br /> Clays and very fine sands 10% <br /> Total 100% <br /> Remnants of virgin gravels on the property show thicknesses of up to 30 feet at the southern end <br /> of the Powless Claim and up to 60 feet at the southern rim of the previously worked gravel on the <br /> Alma Placer Mine �:� +.»t► . are « r+r,t. <br /> December 2017 I-1 <br />
