EXHIBIT "D" MINING PLAN This is a major deposit of red burning clays for the applicant, with a projected 75-year life. Topsoil is thin to non-existent ranging from 0" to 6", and is referred to by SCS as "the surface layer" as opposed to topsoil. Overburden or the substratum vanes from 9" to 42" in depth. There aze 4 sepazate clay deposits included in this permit area, with depths ranging from 6' to 40'. It is possible that the applicant may also mazket some of the caprock at some time in the future. Notice is hereby given that this pit may be operated less than 6 months per year, if business demand so dictates. The applicant requests that this not be considered as temporary cessation. CRS 34.32.5- 112(b)(VIII) states: "A timetable estimating the periods required for vazious stages of the mining .operation. The operator shallnot be required to. meet the timetable, nor shall the timetable be subject ;,,, , . to independent review by the Boazd or Office." (a) Mining Methods There will be 4 sepazate phases in this long-term mining operation. The State lease land on the south and a portion of the Patton lease on the north will be opened at the same time to start this operation.. After the State land is mined out, mining will then proceed north into the BLM property. ~A4itt~gw411- t .Mining will start on the west of the Patton leased azea and move east until material is exhausted. Extraction will normally start at the lowest contour level of .the ore body in each of the phases and proceed into the deposit. Stripping and mining will be performed primarily by front-end loaders and dozers. There may be occasional blasting necessary to loosen the caprock in some azea. This operation will be operated on a floating bond with the affected azea in each phase to be kept at a minimum consistent with operational efficiency. Topsoil - if any -and the limited overburden will be stockpiled on the pit perimeters sepazately for replacement in reclamation as soon as possible. The gradual forwazd movement and the floating bond approach helps keep the distance to move topsoil - if any -and overburden to a minimum, and in effect, reclamation is made part of the ongoing extraction operation rather than being a sepazate cost item. Stockpiling and material re-handling is eliminated except for the start of the operation as described above. Mined clay and possibly caprock will be stockpiled on site for later loading and hauling off site the applicant's brick plant in Pueblo or other job sites in the area.
