main site road and working outwards. The area disturbed would not exceed 25 acres at any time <br /> including haul roads and processing areas. Each of the disturbed areas shown on Map C-2 will be <br /> mined out starting from the main site road and working outwards <br /> An approximate timetable to describe the mining operation is shown on the Map C-2. The life of <br /> this mine may extend beyond the original as listed on the mining plan map, this depends upon <br /> demand for the product this time line may be shorter or longer. This mine will be a year round <br /> operation with no planned extended cessation of operations at this mine site. It is proposed to use <br /> a floating bond on 25 acres on this operation as mining is completed in the mining units as <br /> proposed see Map C-2. The operator estimates that 3 to 5 years will be required to establish the <br /> reclaimed area back to pastureland after the cessation of mining in each area such that may be <br /> considered for release by the Mined Land Reclamation Board of the Division of Reclamation, <br /> Mining, and Safety. The reclamation is an ongoing process as soon as the first unit is deemed to <br /> have enough land area ready for reclamation to start. The sequence of the mining and <br /> reclamation will follow a natural progression, timing is critical and the final reclamation without <br /> an extended delay is the ultimate goal. <br /> As stated in this report the mining and affected land will range between 6.32 to 25 acres with a <br /> maximum of 25 acres being disturbed at any time. Reclamation would be occurring on the lands <br /> mined out concurrently with mining. <br /> The backsloping and final pit floor will continue to be done concurrently with the mining. <br /> Robinson Sons Inc. will continue to reclaim 5 to 10 acres areas as they are deemed mined-out. <br /> This allows the operator the allotted time to establish a planned reclamation plan and continue to <br /> mine hence the 25 acre floating bond. As stated before this site is on an upland terrace deposit <br /> with the following characteristics: <br /> The areas to be mined Lorencito-SarciIlo-TrujiIto complex, 3 to 25 percent slopes Trujilto loam, <br /> 3 to 9 percent slopes. <br /> It is estimated that the deposit is from 12 to 18 feet deep with negligible overburden and from 8 <br /> to 12 inches of topsoil in the area of the deposit. Some overburden will be used to supplement <br /> Robinson Gravel No 1 <br /> September 2018 D-2 <br />
