Project Description• Modular design suitable for expansion, maintenance and trouble-shooting• Design approved by recognized authorities• Cabinets, cabinet wiring and equipment mounting• All software• Gateway services to North America• VoiP (voice over internet protocol), Data, VoiP/Data receptacles for installation by othersusing CAT6 twisted pair cabling2.6.2 AccommodationsThe mine site will be located in order to place the foundations of structures with heavy loads onoriginal ground. Fill is acceptable for lighter structures and for trafficked areas. The mine sitewill be graded to divert surface runoff water away from buildings to perimeter ditches. Thiswater will be collected in sedimentation ponds before being released into the environment.The mine and mine site will be surrounded by perimeter cutoff ditches to intercept surface waterrunoff from the surrounding area. This water will also be collected in sedimentation ponds.Existing water courses that cross the site will similarly be diverted to these ponds.The camp accommodations will be located sufficiently far from the mine to satisfy the safedistance specified in blasting regulations.2.6.3 AirstripThree alternative locations for the mine airstrip have been investigated and have been found to befeasible. Two are close to the option 1 north road alignment and one is close to option 2 southroad alignment. All three alternative locations are feasible, but the location immediately west ofthe point where option 2 crosses Hackett River, which is on a long ridge, is ideal.This location would be close to the access road, and it can be expanded to take larger planes ifnecessary. In addition, this location requires less movement of material for airstrip infill andleveling than other areas under consideration and should result in minimal construction costs. Ananalysis of the prevailing wind direction will be required to confirm the best alignment for theairstrip.The airstrip will be designed in accordance with Transport Canada TP 312E, AerodromeStandards and Recommended Practices, Volume I, Aeroplane Facilities. The airstrip, which willinclude a 160 m safety area at each end, will be 2000 m long.A building containing a small maintenance garage and a waiting room will be located at theairstrip. Potable water will be delivered from the camp for use in a washroom in this building.Sewage from the building will be collected in an insulated holding tank and transported to thesewage treatment plant at the mine site. Power to the airstrip site will be supplied by the campgenerators. Diesel and aviation fuel will be stored at the airstrip in a lined containment.January 2008 Hackett River Project – Project Proposal Sabina Silver CorporationReport Version B.1 2–28 Rescan Environmental Services Ltd.
