14 GEOCHEMICAL DATA AND ANALYSIS <br />Geochemical Data is provided in a report produced by Braun in September 2014. The report <br />found that, based on the sampling performed and laboratory testing, the ability of rock at the <br />site to produce free sulfur is nearly non - existent. This is a result of low concentrations of <br />potentially acid producing minerals on the permit area and the associated gangue and country <br />rock minerals having the ability to neutralize acid which might be produced. The conclusion is <br />supported by data, for many years of operation of this mine, and of other mines in the district <br />including the Cripple Creek and Victor Mine. This conclusion was negated by DRMS personnel <br />with no supporting data. So, in the future, the following items will be followed to insure <br />environmental protection. <br />(a) As no minable acid generating materials have been found, no specific testing is <br />necessary until such time that they are found. If the time comes that rock is discovered <br />which has the ability to cause acid mine drainage or to release designated chemicals, or <br />toxic or acid - forming materials, an evaluation will be made. That evaluation will be <br />specific and appropriate for the types of materials discovered. <br />(b) Whatever necessary evaluations are performed, they will be performed on rock that is <br />deemed representative of the rock requiring testing. <br />(c) Such evaluations shall be appropriate for the intended use or fate of the material <br />exposed or to be exposed during the proposed life of the mining operations, and on a <br />case -by -case basis shall be appropriate for the intended use or fate of the material <br />exposed or to be exposed during the proposed life of the mining operations, including <br />weathering effects, and conditions under which the material will be used, stockpiled or <br />disposed of. <br />(d) Evaluations will be performed on both ore and overburden, and will include the most <br />likely acid producing sources, probable fate, and transport mechanisms that might result <br />in being mobilized by weathering reactions. Those tests are to be determined by a QP, <br />and may include only those tests that are necessary to satisfy the conditions of <br />Subsection 6.4.21(14)(c) above and such evaluations may be prioritized, in descending <br />order of importance, as follows: (i) mineralogical analyses; (ii) trace element analyses; <br />(iii) major element analyses; (iv) microprobe or other comparable analyses. <br />In the event that acid producing materials are found and if net neutralizing, metal adsorption or <br />metal ion exchange potential over the long -term cannot be demonstrated, then operator will <br />perform further testing and analysis to increase certainty in order to protect the environment. <br />0 <br />
