M98177GE <br />I• <br />The proposed conveyor alignment had been cleared of vegetation <br />with some fill placed for the upper approximate two thirds (2 /3) of <br />the proposed alignment. The proposed conveyor alignment slopes <br />down to the southeast at an inclination of about three (3) to one <br />t (1) (horizontal to vertical) and flatter. <br />A small spring was observed about one-hundred fifty (150) feet <br />west of the proposed conveyor alignment in the existing road cut <br />downhill from the last switch back before the mine portal bench. <br />The spring contained a small amount of flowing water. <br />The reclaim tunnel and stacking tube area appears to have been <br />somewhat graded prior to our field study. The stacking tube and <br />reclaim tunnel area slopes down generally to the south with about <br />five (5) feet of topographic relief across the proposed site. <br />The proposed location of the truck load out surge bin slopes down <br />to the southeast with about three (3) feet of topographic relief <br />across the proposed surge bun site. The surge bin site contains a <br />cover of native ground vegetation. The proposed surge bin location <br />appears to be in an area which may have contained structures in the <br />recent past. <br />2.3 Subsurface Conditions <br />The subsurface exploration consisted of observing, describing and <br />sampling the soil materials encountered in eleven (11) auger <br />advanced test borings. The approximate locations of the test <br />borings are shown on Figure 2. The logs describing the soil <br />J materials encountered in the test borings are presented in Appendix <br />A. <br />The soil materials encountered in the test borings consisted <br />generally of various mixtures of clay, sand and gravel material <br />with varying amounts of cobbles to a depth of about fifty-seven <br />(57) feet. The soils varied from sandy and gravelly clay to sand, <br />gravel and clay mixture. The sandy and gravelly clay soils tested <br />have a low to moderate swell potential with some test results <br />indicating high swell potential. The sandy and gravelly clay soils <br />tested have a potential for large amounts of consolidation under <br />heavy loading conditions. <br />No formational material was encountered in our test borings to a <br />depth of about fifty-seven (57) feet, the maximum depth explored. <br />4 <br />Lambert and ~.gsocistes <br />GONSULTHG GEOTEGMMiGL EHGwEE RS •MG <br />M~TERI~L TEStING <br />
