managed underground since the Upper Mountain Top is comprised of extensive, existing underground <br />workings which allow for the retention of materials underground, thereby limiting any surface <br />disturbance. However, a tunnel through host-rock will likely be constructed that will yield the <br />ubiquitous andesite material that may be useful to amend an existing scree slope. Approximately 2,000 <br />yd3 will be placed outside, adjacent to the portal to amend this rock field. It will be contoured to match <br />and amend the existing scree slope. <br />Figure 1 depicts the surface setting of the Lower Mountain Top - which shows the aerial extent of the <br />working pad surface relative to the portal and existing waste rock pile. The entire acreage of the Site is < <br />1.0 acre. Figure 2 demonstrates the various flow pathways. Figure 3 depicts the on-site surface <br />features, the working areas and the amended rock field. The site currently contains a cement pad that <br />may be used for materials sorting if needed, and/or vehicle parking. The approximate area of the <br />'repository' for the tunnel materials is 120 yd L x 10 yd W x -2 yd H and will be placed within an existing <br />cut slope created by the historic pad and access road. There is sufficient room within this cut slope to <br />accommodate the volume of material produced by the tunnel. Figure 4 depicts the site features post- <br />reclamation. The repository area for the tunnel rock will be spread in order to amend the 'cut slope' (as <br />it is currently) into a more blended slope. All other site features will remain intact including the portal, <br />cement pad, existing waste rock piles and access road. <br />In a given day of exploration activity at the Lower Mountain Top, the following step-wise progression of <br />activities will be accomplished: <br />• Underground miners will operate core drill to recover rock samples from inaccessible earth <br />• Underground miners will drill holes to set explosive charges using pneumatic drills <br />• Charges will be set off, and the underground will be allowed to 'clear' before miners return <br />• Loosened rock will be sorted underground (if possible) into categories of waste rock or viable <br />ore <br />• Ore will be transported to the surface via a diesel-powered trammer, and placed into 2-ton <br />super sacks for transport off-site <br />• The above cycle would yield up to 'two' explosive sets per day. <br />All fuel and lubricating fluids are kept in the truck and are not stored on Site. <br />Waste rock Analysis Methods and Results <br />Samples of waste rock from the Lower mountain top were collected and analyzed for toxicity <br />characteristic leachate procedure metals content (TCLP) and acid base accounting (ABA) measures. The <br />TCLP results provide an indication of metals solubility from the waste rock solid matrix. The ABA <br />measures provide an indication of the 'acid generation potential' of the waste rock. The waste rock was <br />collected from the Lower Mountain Top and represents typical waste rock to be produced from the Site. <br />A summary of the data and results is as follows; <br />Table 1 provides a summary of the analysis results for the Lower Mountain Top waste rock solids CV <br />an <br />analysis. There were three samples gathered that represent the majority of the material that comprises a
