GeoScience Services 2263 Kingston Road Grand Junction, CO 81503 (970) 759-6709 The second batch of samples were sent to the Casper, Wyoming branch of Energy Labs Inc for a pH saturated paste, Uranium %, and Vanadium % analyses. The reason for sending samples to two different branches of Energy Labs Inc was that the Casper, Wyoming branchy could perform the pH saturated paste analyses but was not able to do the neutralization potential, acid potential, or acid/base potential analyses. In referring to the sample ID 18w2, the property is designated by the 18 in the sample ID. The w in the sample ID is to designate waste, and the 2 designates which batch the sample is from. In addition to the summaries of the samples, provided below, I have attached the lab results for the analyses performed by Energy Labs. Acid-Base Accounting. Acid-base accounting (ABA) was first developed to evaluate coal mine waste and is based on determining the acid generating potential (AP) as defined by the total sulfur content and the neutralization potential (NP) usually defined as the amount of calcium carbonate present in the rock. Rock samples for the Cotter mines were submitted to the laboratory for analysis of uranium and vanadium contents, pH saturated paste, acid generating potential, and neutralization potential. Results of the Cotter Mines' analyses are presented in Table 1.
