Exhibit B <br />Site Description <br />JD -6 Mine Permit Amendment <br />M- 1977 -310 <br />Soils Information <br />The previously permitted area covers two very different soils environments: the lower <br />mine area on the Mineral Joe 17, 18, and 19 claims on the northern slope of Monogram <br />Mesa, and the existing access roads and vent hole sites on top of Deer Shaft Bench. <br />As part of this Soils Exhibit the pertinent Soil Interpretation sheets, and Map Unit <br />Descriptions derived from the Web Soil Survey for the soil types in the affected areas, are <br />attached. <br />The mine area consists entirely of map unit symbol 23- Bodot, dry -Ustic Torriorthents <br />complex with a typical profile being as follows: <br />0 -3 inches: Cobbly clay loam <br />3 -30 inches: Cobbly silty clay <br />30 -34 inches: Weathered bedrock <br />The rating class for this soil type is poor, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />The existing access roads and vent hole sites consists of two different soil types. The <br />majority of the soil in this area consists of map unit symbol 75- Pinon- Bowdish- Progresso <br />loams with a typical profile being as follows: <br />0 -5 inches: Loam <br />5 -16 inches: Gravelly Loam <br />16 -20 inches: Unweathered bedrock <br />The rating class for this soil type is poor, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />The other soil type in this existing access roads and vent hole sites area consists of map <br />unit symbol 60- Monogram Loam with a typical profile being as follows: <br />0 -3 inches: Loam <br />3 -14 inches: Loam <br />14 -28 inches: Loam <br />28 -60 inches: Sandy clay loam <br />The rating class for this soil type is fair, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />B -1 <br />
