ii iii��ii� <br /> I�� <br /> ir, ni tod) <br /> TABLE 4 <br /> IP <br /> Samples Recommended for Phase 11 Testing FEATfier <br /> co Samples <br /> Denver, Inc. <br /> CTI <br /> C) <br /> AMP <br /> AP7— No measurable pyrite content. Mid NNP range of ANP. <br /> B2 Neutralizing breccia high end of NNP range. Has 6%dolomite and 3%pyrite.Also contains other <br /> carbonate minerals that may not provide neutralization capacity under environmental conditions. <br /> Sulficlic breccia. Has 2%pyrite,siderite, rhodochrosite. High end of NNP range, but these carbonate <br /> B3 minerals may not provide effective neutralization. <br /> Mid range of NNP. Moderate pyrite content.Contains calcian siderite,which may not provide effective <br /> 85 <br /> neutralization. <br /> Sulfidic breccia,with 7%pyrite and 2%calcian siderite. Low end of NNP range.Calcian siderite may not <br /> B7 <br /> provide effective neutralization. <br /> B8 Oxidized breccia. Has alunite pyrolusite, hematite,and goethite but no pyrite. <br /> 612 Near zero NNP value, uncertainty with respect to net neutralizing ability under environmental <br /> conditions.Sample with low pyrite content. <br /> L2 The only lamprophyre sample available. <br /> PC3 The only Precambrian sample.The only sample containing the phlogopite mineral.Average NNP. <br /> PP2 Upper range of measured NNP values and does not have any measurable pyrite. <br /> PP4 Mid range of NNP and does not have any measurable pyrite content. <br /> Lowest NNP of samples recommended for further analysis. Does not contain carbonate minerals but <br /> PP15 Idoes contain silicate minerals. <br /> 0-T' <br />
