No. CMC251125. <br />Tests were performed on three samples of the head ore, two samples of the overburden and a <br />blank test sample of 7.0 pH was used for reference. <br />Sample <br />Past Test (pH) <br />Neutralization <br />Acid Producing <br />Comments <br />Potential (mole <br />Potential <br />H + /IOOKg) <br />(CaCO3 /1000 <br />tons) <br />Ore Sample 1 <br />7.4 <br />30.1 <br /><0.1 <br />(APP)- pH after <br />washing = 7.1; <br />see note <br />Ore Sample 2 <br />7.2 <br />28.5 <br /><0.1 <br />See note <br />Ore Sample 3 <br />7.4 <br />30 <br /><0.1 <br />See note <br />Blank <br />7.0 <br />0 <br />0 <br />Overburden <br />7.5 <br />33 <br /><0.1 <br />See note <br />Sample 1 <br />Overburden <br />7.4 <br />32.4 <br /><0.1 <br />See note <br />Sample 2 <br />NOTE: No signs of acid producing materials (i.e. sulfides) have been found at the Steel Rose <br />Mine to date. In the APP test, introduction of 30% Hydrogen Peroxide resulted in no reaction <br />other than creating an oxidizing solution from all of the mine samples. The oxidizing character of <br />the samples persisted after 24 hours of heating. <br />Additional tests were done for toxic materials, none were discovered. <br />If you have any questions please feel free to contact me. <br />Sincerely, <br />17r-o4���i: Finch. <br />Dr. Robert Finch _- . <br />
