Exhibit I Page 2 TABLE I-1: SUMMARY OF MAPPED SOILS DATA Hydric Map Unit Drainage Farmland Percent of Symbol Soil Type Class Soil Classification Mine Area Rating 69 Valent sand,0 to 3 Excessively 0 Farmland of local 34.9 percent slopes drained importance 70 Valent sand,3 to 9 Excessively 0 Not Prime Farmland 63.7 percent slopes drained 72 Vona loamy sand,0 to 3 Well drained 0 Farmland of local 1.4 percent slopes importance Source:USDA NRCS 2023. The predominant soil type present within the Kersey Mine is Map Unit Symbol 70,that being Valent sand. Based on USDA soil mapping, sand and loamy sand(considered viable growth medium)is typically present to a nominal one ft. depth and is underlain by the mineable sand horizon(typically present to varying depths of up to 30 to 50 ft. below ground surface;often with interspersed clay lenses present)across the Permit Area.CSC has completed numerous soil borings and/or exploration drill holes throughout the Site,virtually all of which verify the presence of sand,presumably of the Valent classification, as being ubiquitous across the Site. A more detailed description of the Valent Series(as described in the USDA National Cooperative Soil Survey; 2008)is provided(in part)as follows: VALENT SERIES The Valent series consists of very deep excessively drained soils that formed in mixed eolian sands. Valent soils are an upland dune topography. Slopes range from 0 to 60 percent. The mean annual precipitation is about 41 centimeters (16 inches), and the mean annual temperature is about 10 degrees C. (50 degrees F.) at the soil type location. Taxonomic Class: Mixed, mesic Ustic Tropopsamments Typical Pedon: Valent sand, grassland. (Colors are for dry soil unless otherwise noted.) A: 0 to 10 centimeters(0 to 4 inches);grayish brown(10YR 5,2)sand, dark grayish brown(I0YR 4/2) moist;single grain; loose: neutral(pH 7.2);gradual smooth boundary. (8 to 25 centimeters (8 to 10 inches) thick) C: 10 to 152 centimeters (4 to 60 inches);pale brown(I0YR 6/3)fine sand, brown(I0YR 5/3) moist; single grain; loose; neutral(pH 7.2). Geographically Associated Soils: This is the Dailey soils. Dailey soils have a mollic epipedon, Drainage and Saturated Hydraulic Conductivity: Drainage: excessively drained. Runoff. low. Saturated Hydraulic Conductivity: high to very high Use and Vegetation: These soils are used principally as native rangeland; however, they are irrigated under sprinkler irrigation in some localities. Principal native revegetation is yucca, sage, cactus, sand dropseed, sand reedgrass, big bluestem, little bluestem, sideoats grama and sand bluestem.
