. Trapper Mining Inc. <br />1995 Deep Development Drill Holes <br />Program Summary <br />A. Site Location <br />Of the seven deep development drill holes proposed for 1995, a minimum of two and possibly four will be <br />drilled within areas of disturbance associated with active pits. Holes 95-LW9 and 95-LW10 aze to be <br />located directly north and south of the D pit area, respectively. It is intended to drill these holes within <br />disturbed areas, though it may be necessary to locate them on undisturbed ground. For this reason, costs are <br />included for the reclamation of these pad azeas. <br />Holes 95-LW 11, 95-LW 12 and 95-LW l4 will be drilled in undisturbed or reclaimed areas and a cos[ for <br />reclaiming them is also calculated. <br />The remaining two holes, 95-LW 13 and 95-LW IS will be located in active areas and therefore no <br />reclamation costs ate calculated. <br />B. Drill Sites Coostructioo and Reclamation <br />Drill sites will be approximately 100' z 150' in size and will be minimized when possible. Assuming I8" of <br />topsoil for this area, 833 BCY or approximately 1,000 LCY (20% swell) of topsoil will be moved per drill <br />site. Typically this will be moved uphill of the drill site for later redistribution. <br />• Leveling and grading of the drill sites is expected to be minimal. It is estimated that no more subsoil than <br />topsoil will be moved, and therefore 1,000 LCY is used for estimating purposes. <br />Drill sites may require the construction of two mud pits per site. Approximate size of each pit would be 12' <br />wide, 25' long and 6' deep. Assuming a swell of 25% each site may require the moving of 167 LCY yards <br />to backfill the pits. <br />All leveling and grading and pit construction will be contained within the stripped area. Because of the <br />minimal area or the drill site no erosion problems are anticipated through silt fence and/or hay bales may be <br />used to contain sediment on site should this become a problem. <br />C. Road Development and Reclamation <br />As noted, up to five holes may be located in undisturbed areas. These have been located on or adjacent to <br />disturbed areas or existing light use roads. At a maximum, each site wuld require that development of an <br />additional 500' of light use road. Allowing for an average width of IS', each site may require <br />approzitnately 0.17 acres be scarified and seeded. <br />Though it is not anticipated, [here may be short sections of existing or constructed light use road that would <br />require minor cuts or fdls. In this case, topsoil would be removed and stored adjacent to the road for <br />redistribution. An estimate for the reclamation of up to 2,000' of approved light use road would include the <br />following. The redistribution of 2,666 LCY of topsoil based on a 20-foot corridor width, 18" of topsoil and <br />a swell of 20%. Regrading would require the moving of 2,083 LCY based on an average width of 15 feet, <br />average depth of l8" and a swell of 25%. <br />~J <br />MWW/jsb 5/95 [DMG\95-MAY05\ <br />
