It should be noted that this disturbed area is the total for the mine life and is represented by a light <br /> blue cyan boundary on Map C-2. Furthermore, that the affected area is the permit area and is <br /> represented by the permit boundary shown in purple on Map C-2. <br /> Only two mining areas will be disturbed at any one time as reclamation will be ongoing. <br /> Therefore,the total area of active mining, as of October 2017, at any one time will not exceed 7 <br /> acres. Exact acreage of mining exclusive disturbance is dependent on the rate of mining and <br /> concurrent reclamation. Currently active mining faces combined with those areas still to be <br /> mined totals 67.7 acres. Therefore,the maximum site disturbance as of October 2017 is 114.5 <br /> acres; however, removal of seeded pre-law areas (21.7 acres) gives a total `to be seeded' <br /> disturbed area of 92.8 acres. <br /> Areas to the north include pre-1977 mine law lands that are in reclamation phase. Due to the <br /> lack of saved topsoil from earlier mining efforts, new topsoil will be created and added to pre- <br /> law areas. Reclamation will be considered complete once vegetation is established. <br /> Anticipated topsoil to be removed and stockpiled in undisturbed future mining areas amounts to <br /> 40,958.5 CY. Partially vegetated berms of overburden and waste fines exist in the northern and <br /> southern extents of the site as well as a large north-south trending berm along the western extent <br /> of the site. These berms contain 24,960 CY. The anticipated overburden in all unmined areas to <br /> be removed and stockpiled totals to 710,056.6 CY. However, estimates on overburden <br /> availability is highly variable due to the inconsistent thickness of the gravel deposit and <br /> overlying strata above the gold-bearing gravels and underlying bedrock. Estimates were based on <br /> the soils report and existing operations as of October 2017. <br /> All fines,topsoil, and overburden stock piles will be constructed to 2.5H:1 V slopes and will be <br /> seeded and mulched when they are in place over 180 days. The rangeland seed mix found in <br /> Exhibit E will be used for seeding stockpiles when needed. <br /> 5. Flocculant Use <br /> The Alma Placer may use flocculant at times to improve the recycling process of wash water <br /> used in gold-bearing gravel processing. Flocculant is used in water recirculation systems in <br /> mining operations that involve significant material washing. A mild flocculant will be used to <br /> Alma Placer Mine t.rr�t r+arli�ixt hsu.utrs Y!0,[" <br /> December 2017 D-10 <br />
