GeoScience Services 2263 Kingston Road <br />Grand Junction, CO 81503 <br />(970) 759-6709 <br />The second batch of samples were sent to the Casper, Wyoming branch of Energy Labs <br />Inc for a pH saturated paste, Uranium %, and Vanadium % analyses. The reason for <br />sending samples to two different branches of Energy Labs Inc was that the Casper, <br />Wyoming branchy could perform the pH saturated paste analyses but was not able to do <br />the neutralization potential, acid potential, or acid/base potential analyses. <br />In referring to the sample ID 18w2, the property is designated by the 18 in the sample <br />ID. The w in the sample ID is to designate waste, and the 2 designates which batch the <br />sample is from. In addition to the summaries of the samples, provided below, I have <br />attached the lab results for the analyses performed by Energy Labs. <br />Acid-Base Accounting. Acid-base accounting (ABA) was first developed to evaluate <br />coal mine waste and is based on determining the acid generating potential (AP) as <br />defined by the total sulfur content and the neutralization potential (NP) usually defined <br />as the amount of calcium carbonate present in the rock. Rock samples for the Cotter <br />mines were submitted to the laboratory for analysis of uranium and vanadium contents, <br />pH saturated paste, acid <br />generating potential, and neutralization potential. Results of the Cotter Mines' analyses <br />are presented in Table 1. <br />Table 1 Laboratory results of rock samples from the waste and ore piles at the JD- <br />6, JD-8, JD-9 and the SM-18 mines. <br /> <br /> <br />Vanadium <br /> <br />% <br /> <br />0 <br /> <br />0.04% _., <br /> <br />0.36% <br /> <br />0.11% <br /> <br />0.40%~ <br />-- <br />" 0.07% <br /> <br />0.58% <br /> <br />0.08% 0:65% <br />H saturated aste <br />.. s.u. 0.1 8.7 <br /><: 8.6 <br />- i - 8.5 7.8 8.2 7.7 7.9 7.8 <br /> <br />Uranium <br />% . <br />0 ` <br />, 0.007% <br />0:075% <br />0.027% ~~ ,, . <br />0.132% 0.009%' <br />0:146% <br />0.008°10 0.158%; <br />::Vanadium ~ % 0. 0:02% .0:27%' 0.07% 0:34°h 0:04% 0.46% '. 0.06% " .;.0:47%` <br />4 <br />
