YOAST MINE <br />2017 ANNUAL RECLAMATION REPORT (ARR) <br />2017 DISTURBANCE AREA <br />There were no additional acres disturbed during 2017. The total disturbed area in 2014 (2014 ARR) was <br />calculated at 848.6 acres. A Bond Release Tracking Initiative initiated by Seneca Property, LLC (SP) in <br />2014 consolidated all previous mapping information in a GIS (Geographic Information System) format, <br />resulting in a corrected disturbance area of 850.5 acres. For 2017, the physical disturbance boundaries and <br />areas are the same as shown on the 2014 Planned Reclamation Map. <br />BACKFILLING AND GRADING <br />No additional areas were backfilled and graded in 2017. <br />SOIL AND SPOIL MONITORING <br />SP is required to monitor soil and spoil handling operations, including salvage, storage, and redistribution <br />of soil/spoil for Yoast Mine. In 2017, no soil or spoil material was salvaged, stored, or redistributed and <br />no soil/spoil sampling or monitoring was conducted. <br />Soil Recovery Documentation. No additional soil or spoil was salvaged during 2017, since no new <br />disturbance occurred. <br />2016 Soil Replacement Thickness. No soil or spoil materials were replaced during 2017. <br />Soil Pit - Soil Fertility and Spoil Suitability. Given that no soil or spoil materials were replaced, no soil <br />fertility or spoil suitability samples were collected or analyzed in 2017. <br />Soil Balance. Given that no additional soil/spoil salvage or replacement occurred during 2017, the <br />previously calculated soil balance remains unchanged. It should be noted that the revised disturbance <br />acreage previously noted does not affect the soil balance carried forward from previous ARR's. Soil/spoil <br />materials have been replaced on all mining disturbance areas not identified for permanent retention to <br />support the approved postmining land use(s). Remaining soil/spoil stockpiles are associated with the <br />identified permanent retention areas. <br />Soil Salvage and Storage. The life -of --mine disturbance area from which topsoil was salvaged (850.5 <br />acres) and the topsoil stockpile sites as of December 31, 2014 are shown on the 2014 Topsoil Replacement <br />map. The stockpile volumes are listed in Table 1, Soil Stockpile Volumes. As of December 31, 2017, <br />there were 36.7 acre-feet of stockpiled topsoil remaining in the mining area. <br />Soil Replacement. No soil was replaced during 2017, therefore the total remaining mine disturbance area <br />designated for permanent retention is 4.9 acres. <br />Soil Replacement Thickness. Dividing the stockpiled soil volume available by the remaining <br />disturbance area (designated for permanent retention), the soil material balance provides for a soil <br />replacement depth approximately 4.5 feet for the remaining disturbance area. This generalized soil balance <br />does not account for any area variations or for permanent facilities not requiring topsoil; it is strictly an <br />area -wide average. The remaining disturbance area essentially corresponds to the mine entrance road and <br />3 <br />
