MILL SITE EARTHWORKS FIELD MONITORING SUMMARY (WEEKLY REPORT) <br />Project Title: Mill Site Earthworks <br />Owner: Cripple Creek & Victor Gold Mining Co. <br />Location: Cripple Creek & Victor Gold Mine <br />Work Element: Mill Site Earthworks <br />Date: April 7, 2012 <br />Reporting Period: 4/1/2012 through 4/7/2012 <br />Days <br />S <br />M <br />T <br />W <br />T <br />F <br />S <br />Work Shifts <br />D <br />D <br />- <br />- <br />D <br />D <br />D <br />N <br />N- <br />N <br />N <br />N <br />N <br />D = Day Shift <br />N = <br />Night Shift <br />Project No.: 84201125K0 <br />Contractor: Ames Construction Co., Inc. <br />Shift: Day /Night <br />Ambient Temperature Range (F): Low: 18 °F to 37 °F ( + / -) High: 32 °F to 54 °F <br />AMEC CQA: Personnel On -site through the Reporting Period (See Attachment A). <br />Ames: Work activities were paused before the beginning of day shift on 4/3/2012 and resumed at the <br />beginning of night shift on 4/4/2012. This was done due to a snowstorm and slick haul routes. <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) Earthworks <br />A) Topsoil Stripping <br />No work performed during the week. <br />B) Clear and Grub <br />Seedmasters were onsite to remove trees and shrubs from the remaining area to be cleared and <br />grubbed. A John Deere 240 excavator was used to clear and grub the area that could be <br />accessed due to fill progression in the area. The removed trees and shrubs were hauled to the <br />topsoil stockpile designated by CC &V to be chipped. <br />C) Subgrade Preparation <br />Subgrade preparation was performed prior to overburden 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 CAT 773 water <br />truck. Compaction was performed using a 10 -ton vibratory smooth drum compactor passing over <br />the entire subgrade surface at least four times. The subgrade was inspected and approved by an <br />AMEC field representative, prior to fill placement. <br />In most areas, excluding flat areas were fills are started, the subgrade is keyed into as the fill <br />progress. This is due to steep slopes that are adjacent to most fill areas. In this instance, the <br />subgrade is inspected for organics and debris by an AMEC field representative prior to fill <br />placement (keying into the subgrade). <br />MEW Weekly Report WE 04.07.2012 <br />
