EXHIBIT L WORST CASE RECLAMATION SCENARIO <br /> Mining at the Box Creek Placer Mine will mine an additional 170 (unmined as of April 2018) <br /> acres of land and, combined with redisturbance of previously mined area, a total of 300 disturbed <br /> acres will exist over the course of the mines `second' life. At any given time, a maximum of 30 <br /> acres of ground will be disturbed broken into three 10 acre areas: the previously mined area in <br /> reclamation not to exceed 10 acres,the current 10 acre mining and processing area, and another <br /> <10 acres in preparation of mining. An additional approximately 10 acre settling pond and <br /> processing area will require topsoiling and seeding. The previously mined area in reclamation <br /> will already have overburden placement and grading, topsoil application, and will only require <br /> seeding in the worst case scenario. The active mining and processing area will require <br /> backfilling, grading,topsoil placement, and seeding. While the future mining area will require <br /> topsoil and seeding in the case that disturbance in that area has begun. <br /> By using on-site excavated materials,the distance that topsoil and overburden will have to be <br /> transported as well as the amount of material that will have to be rehandled will be minimized. <br /> Additionally, the acreage that is unreclaimed will be minimized and will make the worst case <br /> reclamation smaller and thus a smaller bond will result. <br /> Given the length of time it will take to mine this entire site (24 years),the Operator will not <br /> phase the operation and the bond. Bond costs and related tasks can be seen in the list and table <br /> below. <br /> • Mobilization of equipment<45 miles = $6,000.00. <br /> • Sediment settling pond grading=4 inches of topsoil resurfacing over 15 acres= 8,067 <br /> CY at$1.50/CY= $12,100.50. <br /> • Active mining area backfilling(approximately 20 feet over 1 active mining acre) and <br /> grading to 3H:1 V. Roughly 32,267 CY of dozer work at$0.50/CY = $16,133.00. <br /> • Topsoil surfacing=20 acres at 4 inches deep = 10,756 CY at$1.50/CY = $16,134.00. <br /> • Rangeland revegetation = 30 acres + 15 acres, $820/acre rangeland seed mix= <br /> $36,900.00. <br /> Garrett Pit Gin 1. kki and Associates.P1.1.f <br /> September 2018 L-1 <br />
