[6.4.21(7)] Facilities Evaluation <br /> The site of GTM is the former location of Golden Nugget, Donna Juanita & <br /> Gladstone mines. The legacy stockpiles are neither acid-forming nor hazardous <br /> material according to analytical results provided herein as Appendix D. This material <br /> will be used during site development as fill dirt during road construction, feed hopper <br /> ramp construction and backfilling the mill building. There is no acid mine drainage <br /> from any adits or tunnels on the site. <br /> No designated chemicals will be used in processing. The feedstock is tested <br /> for potential acid-forming material prior to acceptance for processing. Only feedstock <br /> that meets the material acceptance criteria will be received at GTM. The ball mill and <br /> shaker tables are a gravity separator that utilizes only water in processing. The ball <br /> mill and shaker table are located inside the metal building. <br /> GTM is an enclosed operation. Neither the feedstock nor the byproducts, the <br /> two stockpiles outside the building, has the chemical ability to geochemically alter <br /> naturally occurring geologic and geochemical conditions. No potential for release of <br /> designated chemicals exists on site. No containment facilities are proposed. <br /> Because GTM is enclosed in a commercial metal building, monitoring systems <br /> outside the building are not proposed. The process water circuit will be tested for pH <br /> twice daily after the dewatering screen. The pH will be tested with either a pH meter <br /> or litmus paper with the target pH range from 6.5 to 8. In the event of upset <br /> conditions, process water will be diverted to a holding tank. <br /> [6.4.21(8 and 9)] Ground Water Information <br /> The GTM is contained within a commercial metal building that will be <br /> constructed according to commercial building code including foundation and concrete <br /> floor design. Groundwater will not be impacted or intercepted by the GTM. <br /> [6.4.21(10 and 11)] Surface Water Information <br /> Exhibit E includes the engineered drainage plan for stormwater runoff as <br /> roadside ditches. All milling and processing will occur inside the commercial metal <br /> building. Site runoff will be limited to only that storm water during precipitation <br /> events or snow melt events. <br /> [6.4.21(12)] Water Quality Monitoring Plan <br /> Because GTM does not use designated chemicals, does not process acid- <br /> forming materials or produce acid-forming materials and because the mill process is <br /> enclosed in a metal commercial building, a water quality monitoring plan is not <br /> provided nor is a CO Discharge Permit required. <br /> [6.4.21(13)] Climate <br /> No liquid containment systems are planned or open to the environment. <br /> [6.4.21(14)] Geochemical Data and Analysis <br /> No mining, on-site solution containment systems or facilities or disposal of <br /> material will occur on site. Feedstock material and byproducts will be stockpiled on <br /> site in concrete containment structures in limited quantities. <br /> Page 17 of 21 <br />
