A <br /> generally included the same soil type materials encountered in holes 1 <br /> and 2, (i.e. silty, clayey gravels with cobbles and boulders). No bedrock <br /> was encountered in any of the test holes to elevation 9374.5 feet, the <br /> maximum depth of exploration. <br /> Free water was encountered in 6 of the holes at depths of 14 to 48 <br /> feet, (elevations 9425 to 9386 feet). Generally, the free water was encountered <br /> in either the natural in place deposits, or in the slime tailings. Where <br /> only sand tailings were encountered in the test holes, no water was present <br /> or it was at, or below the on inal ground surface. Holes 4 and 7 were <br /> cased with 1.5 inch perforated PVC pipe for subsequent ground water monitoring. <br /> Test holes 8, 9 and 9A encountered what is believed to be an historic <br /> tailings pond below elevation 9430 feet. In these test holes most of the <br /> tailings encountered below this elevation were slimes. It is evident that <br /> historic tailings also compose the base of the road along the south side <br /> of the embankment. <br /> LABORATORY INVESTIGATION AND TESTING <br /> As the samples arrived in the laboratory, the field descriptions were <br /> carefully reviewed and the soils classified into similar units of engineering <br /> properties. During this examination, emphasis was given to the engineering <br /> properties involved in the soils encountered. Samples designated for testing <br /> were then correlated between holes for similar types of material and properties. <br /> Where samples were not suitable for testing, or where samples were not <br /> obtained, strength values were assumed or correlated with the field tests <br /> for the analysis. Following the correlation of samples of similar types <br /> c� of material , the laboratory testing program was initiated and included the <br /> following types of tests: <br /> -3- <br />
