Box 82 <br /> Nucla, Colorado 81424 Nucla, Colorado 81424 <br /> Wounded Knee, LLC <br /> P.O. Box 555 <br /> Nucla, CO 81424 <br /> III. Summary of Reclamation and Management <br /> A. General Description <br /> As shown on Map 1, 85.5 acres are requested for Phase I bond release. Final backfilling and <br /> grading (including topsoil replacement and seeding) occurred in 2023. The bond release areas <br /> are comprised of two distinct parcels split by a permanent road. <br /> The work completed for both bond release parcels included backfilling and final grading to the to <br /> the approved post mine topography (PMT). Topsoil and seeding also occurred during final <br /> grading activities. <br /> The bond release areas have been regraded for the most part consistent with the approved post- <br /> mining topography. Please refer to Map 2.05.4-1 in Permit No. C-1981-008. However, as <br /> shown on the comparison profiles for the final backfilled surface and the approved PMT on Map <br /> 2, the final surface has some deviation from approved PMT in the drainage locations. <br /> This occurred due to an excess of Bench I and topsoil onsite for the final reclamation of the <br /> mine. To ensure all Bench I and topsoil was utilized completely during the final reclamation of <br /> the mine, it was determined that the excess would be place in the drainages to shallow up the <br /> overall grades of slopes entering the drainages and the thalweg of each respective drainage. The <br /> final surface created is flatter, a more erosional stable surface, and also allowed New Horizon to <br /> fully consume remaining Bench I and topsoil stockpiles onsite to support final closure of the <br /> mine. <br /> SL-27 Phase I Bond Release Page 3 <br />
