The entire access road is not shown due to its length and the scale of the site map. The <br />entire access road is shown on the PROJECT LOCATION MAP, 1" = 300' submitted on <br />February 6, 2003 with the update on the Sunday Mine, Permit M-1977-285; this regional map <br />shows all features associated with the Sunday group of mines. <br />East Edge of Dumn; Slopes and Gradients; Area North of Dumb <br />The eastern dump toe is less than 10 feet from drainage thalweg; provide slope <br />gradient information and sediment control measures. The area to the north of the dump needs <br />to be shown correctly on the map. <br />Response: <br />Runoff around the eastern side of the dump follows the dump toe and leads to a <br />catchment berm around the periphery of the dump toe; no runoff escapes to the drainage <br />thalweg. The current site surveys were conducted using GPS. For every measurement point <br />on the map, an elevation is available as well as the `x' and `y' locations of the points. Spot <br />elevations have been printed on the map to aid in determining slope gradients as well as in <br />preparing final reclamation contour maps. <br />The area to the north below the dump toe has also been surveyed and is shown <br />correctly on the new site map. At present, the main features in this area are the catchment <br />berms. <br />Topsoil Stocknile; Power line Location: <br />Provide an estimate of the volume of the existing topsoil stockpile and describe how it <br />is protected. Show the correct location of the power line. Are there other electrical structures <br />on site? Show electrical installations and note ownership. <br />Response: <br />The existing topsoil stockpile contains approximately 350 yd3 of topsoil. The <br />stockpile is stable and secure as it located on a slope that does not collect runoff and which is <br />not in any drainage paths. The pile has revegetated naturally and is not eroding. <br />The power line location shown on the map submitted by the Operator in 1998 is not <br />correct in relation to the dump. The power pole noted in the inspector's review did not in fact <br />stand in the middle of a topsoil stockpile as shown on the map submitted by the Operator in <br />1998; the pole was in undisturbed ground adjacent to the dump toe. The new site map <br />submitted with the Annual Report shows the current and correct relationship between all <br />features at the Topaz Mine site. The power line into the Topaz Mine has been removed by the <br />local power provider. No electric transformers remain on site, although electric switchgear is <br />still present. <br />Drill Road and Diversions: <br />The original 1980 site map showed a drill road and drill hole location on the hill above <br />the portal. In 1997 diversions were observed, and these need to be shown on the map. <br />Resnonse: <br />The updated map submitted with the Annual Report on January 28, 2003 shows the <br />diversion structures on the hill above the portal. <br />2 <br />
