iii iiiiiiiiiiiiiiii <br /> <br />(/ <br />Results <br />Trapper's approved Mining and Reclamation Permit (C-81-010), specifies annual sampling of recon- <br />toured spoils in the Ashmore and Flintlock pit areas. Section 2.7.2 of permit C-81-010 addresses the <br />specifics of these requirements. <br />Map 41 illustrates the Ashmore pit area recontoured in 1998 and the spoils that were mapped and sam- <br />pled. <br />4.1 Methods <br />The 1998 mapping units were determined by the visual and textural difference of the surtace spoils. <br />Each sample of spoil was a composite from various areas within each mapping unit, from at least aone- <br />foot depth of material. Four composite samples were taken in 1998. Again Map 4-1 presents these <br />mapping units along with the sample number, texture and year sampled. <br />4.2 Results <br />Spoil samples were analyzed for the parameters outlined in Table 2.7.2a of Trappers mining and recla- <br />mation permit. The 1998 laboratory analysis was performed by the Colorado State University Soil <br />Testing Laboratory. The lab results are presented on Table 4-1. Table 42 shows the suitability ratings <br />of the 1998 samples as compared to the suitability ranges presented in permit Table 2.7-2a. Further <br />comparison of the 1998 samples to historical topsoil and spoil samples is presented in Table 4-3. <br />Doc Date:12/11/2001 <br />4.3 Discussion and Recommendations <br />The purpose for annual spoil sampling and analysis is to demonstrate that the recontourod surface spoil <br />layer has acceptable physical and chemical properties to promote plant growth and successful reclama- <br />tion. The 1996 data again shows no problems and continues to indicate that Trapper is accomplishing <br />this goal. With replacement of suitable topsoil, all recontoured spoils should provide an excellent <br />medium for plant growth for any desirable postmine land use. <br />LWH 2197 <br />[DMG~96REPT4] <br /> <br />
