Cross Gold Mine <br />December 2024 <br /> <br /> <br />Exhibit I Soils Information <br />Soils were mapped at the Operations Area by Walsh Environmental Scientists and Engineers, LLC, <br />(Walsh 2008b) and the following descriptions are from the Walsh report. <br />“Soils at the site are generally divided into three types, with different types north of the Coon Track <br />Creek wetland, south of the Coon Track Creek wetland, and the Coon Track Creek Wetland itself. Soils <br />north of the Coon Track Creek wetland area, which is an area previous development sometimes <br />referred to as “Caribou” or “Idaho Tunnel site”, are characterized by NRCS as Leighcan-Catamount <br />families, 5 to 40 percent slopes. NRCS further categorized this soil type as found on Mountain slopes <br />and composed of residuum and/or slope alluvium derived from igneous and metamorphic rock.” Soil <br />depths are shallow and are above very cobbly or graveling deposits. It is somewhat excessively <br />drained. <br />“Soils within the Coon Track Creek wetland area, which divides the site down the middle, are <br />characterized by NCS as Gateview family – Cryaquolls complex, 0 to 15 percent slopes. NRCS further <br />categorizes this soil type as found on alluvial fans or terraces and composed of gravelly alluvium and/or <br />gravelly glaciofluvial deposits derived from igneous, metamorphic, and sedimentary rock. It is well <br />drained.” <br />‘Soils south of the Coon Track Creek wetland area, which is an area of previous development referred <br />to a “Cross”, are characterized by NRCS as Leighcan family, 50 to 40 percent slopes. NRCS further <br />categorizes this soil type as found on mountain slopes and composed of colluvium over residuum <br />weathered from igneous and metamorphic rock.” Soil is very cobbly sandy loam to 9 inches and very <br />sandy loam to 38 inches. It is somewhat excessively drained. <br />Expansion of the permit area with this conversion incorporates additional soil types that are discussed <br />in Appendix I-1.
