Rocky Mountain Industrials <br /> ROCKY MOUNTAIN 6200 S.Syracuse way,Suite 450 <br /> t N D u S r R I A L S Greenwood Village, CO 80111 <br /> Site Geology <br /> Mining Plan <br /> The mining plan for the Mid-Continent Quarry is currently being developed to be presented to the BLM <br /> for their comment and ultimate approval.The future mining plan will continue to utilize drilling, <br /> blasting, mechanical breaking, heavy mobile equipment, crushing, and screening.The difference in <br /> current mining operations and future mining operations will be in how those methodologies are applied <br /> on-site. <br /> The mining operation will switch from a south to north mining face progression to a predominately west <br /> to east mining progression. The primary reason for this switch is to ensure the safety of personnel <br /> operating at the quarry. In the west to east mining sequence, <br /> This blasting and release <br /> will then be mined in a benched configuration with bench <br /> dimensions being determined by the findings of our geotechnical report and in consultation with our <br /> mining engineers.This pattern of blasting and releasing <br /> = will progress across the face of the operation, in strips, from west to east. <br /> Through conversations with our geotechnical engineers and our mining engineering consultants,we <br /> determined the safest and most stable long-term option for slope stability would be achieved through <br /> the complete removal of the . Since they were found to <br /> this option became a reasonable plan.This would result in <br /> the quarry boundary <br /> Monitoring, Stability, and Safety <br /> RMRA will engage in two forms of monitoring over the life of the quarry. First, daily visual inspections of <br /> the highwall will be conducted whenever there are quarry personnel on site.These inspections will <br /> include looking for any signs of movement or rockfall since the last inspection, noting any water seepage <br /> in the layers, and listening for any rock movement or small rockfall activity. The second form of <br /> monitoring will be an annual inspection of the site by our geotechnical engineer.This inspection will <br /> take a closer look at the quarry highwall to determine if there are any signs of movement, shifting, <br /> swelling, or seepage. A brief report will be provided to RMRA after this inspection. <br />
