Seedmasters mobilized to site Tuesday January 3, 2012 to perform clear and grub <br />activities. Frontier Environmental Services Inc. mobilized to site Tuesday January 3, 2012 to relocated <br />the structure at Underground Working #4008 (Morning Glory). <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) Earthworks <br />A) Topsoil Stripping <br />Topsoil stripping within the Mill Site Earthworks project was performed using various CAT dozers <br />pushing the material into temporary stockpiles. The temporary stockpiles will be hauled to a <br />stockpile designated by CC &V at a later date. <br />B) Clear and Grub <br />Clear and grub activities were performed by Seedmasters for the Mill Site Earthworks project. A <br />Hitachi 160 excavator, a John Deere 135 excavator, and a CAT D -6 dozer were used to removing <br />trees and shrubs from the area. These trees and shrubs will be hauled to the topsoil stockpile <br />area designated by CC &V and will be chipped and mixed into the topsoil as it is placed. <br />C) Subgrade Preparation <br />Subgrade preparation was performed prior to structural fill placement in the areas shown on <br />Figure 1. Various CAT dozers were used to rip the existing surface to a depth of at least 6 inches. <br />Moisture conditioning of the subgrade was performed (when necessary) using a tandem axle <br />water truck. Compaction was performed using a 10 -ton vibratory smooth drum compactor passing <br />over the entire subgrade surface at least four times. The subgrade was inspected and approved <br />by an AMEC field representative, prior to fill placement. <br />MEW Weekly Report WE 01.07.2012 <br />
