ACZ Laboratories tested each of the samples for total sulfur, pyritic sulfur, and for sulfate sulfur. Acid <br /> generation potential (AGP)was determined using EPA Method M600/2-78-54-054-3.2.4,acid <br /> neutralization potential(ANP)was determined using EPA Method M66/2-78-054 1.3, and the acid base <br /> potential(ABP) result was reached using EPA Method M66/2-78-054 1.3. The results are tabulated in <br /> Table 1 below with Laboratory reports attached as Appendix A. <br /> Table 1 <br /> Acid Base Accounting Data for Mineral Mountain Project <br /> Source -ACZ Laboratories,Inc. <br /> Acid Acid Acid <br /> Generation Generation Neutralization Acid Base <br /> Potential* Potential** Potential Potential' <br /> (ton (ton (ton (ton <br /> Sample CaCO3/kton) CaCO3/kton) CaCO3/kton CaCO3/kton Sample Description <br /> Structure-Sample across <br /> MH-1 28 24 24 0 mineralized structure <br /> Country Rock-non-mineralized <br /> MH-2 1.9 0.3 13 13 <br /> One-inch wide vein <br /> MH-3 97 75 7 -68 <br /> Standard- Lithic tuff with <br /> known percentage of metal <br /> sulfides(5%by vol) <br /> M H-4 124 105 15 -90 <br /> Standard-Sulfide in Quartz <br /> Vein-25%pyrite,5%galena,5% <br /> sphalerite,60%quartz,and 5% <br /> calcite(by vol) <br /> MH-5 391 331 16 -315 <br /> Notes: <br /> * Calculation using Total Sulfur <br /> ** Calculation using Pyritic Sulfur <br /> Calculated using Pyritic Sulfur <br /> A review of Table 1 shows the results of the three samples. Column 1 contains the sample number, <br /> column 2 shows the AGP based on total sulfur, and column 3 is AGP based on pyritic sulfur. Column 4 <br /> shows the ANP of the sample,and column 5 produces the ABP value based on the pyritic sulfur. Note <br /> that while the total AGP value in column 3 is larger of the two AGP values,the number in column 2 also <br /> includes the sulfate component,which is not available to be mobile in this environment. The results <br /> show that the country rock(Sample MH-2) is acid neutralizing with an ABP of 13. Sample MH-1, <br /> 5 <br />
