(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1987-074 <br />INSPECTION DATE: 6/25/2008 <br />INSPECTOR'S INITIALS THM <br />OBSERVATIONS <br />This inspection was conducted as part of the normal monitoring program established by the Colorado Division of <br />Reclamation, Mining and Safety. The Dotsero Quarry is located 2 miles northeast of Dotsero, Colorado off of the <br />frontage road North of I-70, in Eagle County. The site is a 112c operation that consists of 65.52 -acres. Jeff <br />O'Connell with the Glenwood Springs BLM and Gerry Mayne with Mayne Industries were present during the <br />inspection. <br />The mine identification sign was in place and in compliance with Rule 3.1.12. The permit boundary markers were <br />not identified during the inspection. Please provide photo documentation to this office that demonstrates boundary <br />markers are located around the entire perimeter of the mine no later than the date indicated on the last page of this <br />report. <br />The pit is currently active and various pieces of equipment were observed within the permit area. The active area of <br />the mine activity is taking place on the slopes located at the north edge of the permit boundary which appears to be <br />in Phase 2 of the mine plan. It appeared that the mine operation was following the approved mine plan. <br />The reclaimed slopes appear to be at or near the approved 2H:1 V. Vegetation on the reclaimed slopes consisted of a <br />variety of grasses and shrubs. Topsoil and overburden stockpiles were observed at the east end of the permit area. <br />The topsoil appeared to have adequate vegetation to provide stability and protection against erosion. <br />In an effort to ensure the financial warranty remains adequate to reclaim this site per the requirements of the <br />approved reclamation plan, DRMS will update the reclamation cost estimate. The estimate will be forwarded to the <br />operator under separate cover. The last bond calculation was done in 2006. <br />A variety of weeds were observed within the permit area but none appeared to be noxious. <br />Photos that show the conditions observed during the inspection are included at the end of this report. <br />Responses to this inspection report should be directed to Travis Marshall at the Division of Reclamation, Mining <br />and Safety, Grand Junction Field Office, 101 South 3`d Street, Room 301, Grand Junction, Colorado 81501, phone <br />no. 970.623.5596. <br />I & E Contact Address <br />NAME: Gerry Mayne <br />OPERATOR: Mayne Industries, Inc. <br />STREET: P.O.
