(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1977-023 <br />INSPECTION DATE: 7-7-05 <br />OBSERVATIONS <br />INSPECTOR'S INITIALS GRM <br />This inspection was conducted as part of the normal monitoring program established by the Colorado Division of <br />Minerals and Geology. The Redi-mix Pit is a 112c permitted site located south of the Gunnison Airport on CR 38. <br />Mr. Ed Stewart, representative for the permiee accompanied the inspectors on site. <br />The appropriate sign was noted posted on the gate at the access to the mine site. Fence lines primarily delineate <br />boundaries. <br />The site is active with excavation continuing in Tract B. The Division has some concern regarding the depth of <br />mining in regards to highwall stability. The depth of the excavation appears to be getting close to a point where the <br />alluvial deposits around it may become unstable. Given the fact that excavation is very close to the permit <br />boundaries, off-site damage may become an issue. Although not listed as a problem currently, it is being listed as an <br />issue of concern. The Division is requesting a stabili analysis of the hi wall slopes in relationship to the depth of <br />minine. A qualified engineer or geo-technical firm must do the analysis. This issue is noted at the end ofthis report <br />with a submittal date. <br />The depth could have a major impact on the reclamation bond as it is required that a 3:1 slope be created 10 feet <br />above and below the waterline and 2:1 thereafter. Staff is unsure whether there aze enough materials on site to re- <br />establishsuch slopes without importing materials from other sources. Please supply the Division with calculations <br />showing the amount of materials necessary to re-establish the required slopes and the materials on site dele ated to <br />this task. This issue is noted at the end of this report with a submittal date. <br />There currently is no reclamation under way on site. It maybe in the operator's best interest to look at some areas in <br />Tract A and assess if some reclamation can begin. Reclamation of some lake slopes will keep reclamation costs <br />down overall. It was noted that topsoil stockpiles had roads built on top of them. Roads compact the topsoil and <br />have a deleterious effect on it. It is recommended that the operator stockpile topsoil in less traveled areas. <br />No noxious weeds were noted within the permit boundaries. The operator appeazs to be doing a good job of <br />monitoring for invasive species. <br />The bond is due for a periodical review. The inspector will wait for Valco materials calculations before <br />recalculating the bond. If there is a shortage of materials, the Division will be required to bond for importation of <br />any shortfalls. <br />Responses to this inspection report should be directed to Russ Means at the Division of Minerals and Geology, Grand Junction <br />Field Office, 101 South 3rd Street, Room 301, Grand Junction, Colorado 81501, phone no. 970-241-1117. <br />I & E Contact Address cc: <br />^ CE <br />NAME: Ed Stewart ^ BL <br />OPERATOR: Valco Gunnison Concrete ^ FS <br />STREET: P.O.
