r <br /> Sampling of mineralized fines generated through screening operations will be undertaken at a high <br /> frequency, initially at one composited sample(one grab sample per each 500 CY,then every 10 grab <br /> samples composited) per 5,000 CY,and sampled for Acid Base Accounting,and leachability test-work at a <br /> minimum EPA Method 1312(Synthetic Precipitation Leachate Procedure or SPLP modified to include zinc <br /> analysis on the leachate),and if any issues are discovered from the ABA or SPLP,then further analysis <br /> with Meteoric Water Mobility Testing or MWMT). If the mineralized fines are accumulated on-site and <br /> are potentially acid-generating,then adaptive management procedures will be reviewed with the <br /> Division and implemented immediately upon such review, including use of the following management <br /> tools: <br /> 1.)Compaction of placed fines,and/or; <br /> 2.) Further amendment with lime or limestone-rich materials,and/or; <br /> 3.) Isolation of the fines beneath an inert cover material from the sorter;and/or <br /> 4.) Placement of a revegetated cover. <br /> Preference will be given to taking the fines off-site for processing at the Mill. If left for disposal on-site, <br /> the fines will be placed and compacted (and amended or isolated if necessary and appropriate)to <br /> prevent accumulation of more than 10,000 CY of fines. <br /> Locations of these activity areas are shown on the Exhibit E Mining Map. <br /> The mining plan will proceed until the stock of existing, on surface waste rock considered to yield <br /> economic values within the permit areas have been exhausted. At this point the operator will <br /> commence final reclamation. <br /> The permit boundary will be clearly delineated via marked berms, large boulders,and High Viz marked <br /> posts. Mine Water will conduct site training with all employees to ensure that no disturbance or mining <br /> activity will occur outside of the permit boundary.This boundary will be routinely checked to ensure it is <br /> in proper working condition and visual to all employees. <br /> MineWater has identified approximately 180,000 cubic yards of waste rock,comprised of 130,000 cubic <br /> yards of material at the South London Stockpile,and 50,000 cubic yards in the Lower waste rock <br /> stockpile at the Central/Sorting Plant area. MineWater expects to remove 40,000 cubic yards of ore for <br /> off-site milling,and to replace 140,000 cubic yards on-site at the South London Stockpile Area. <br /> MineWater expects that the fines are about 25%of the total volume,or 45,000 cubic yards. <br /> MineWater has estimated a maximum volume size for the following stages of the process: crusher feed <br /> (10 cubic yards in feed hopper, no stockpile of crusher feed is planned),sorter feed from which fines <br /> have been removed (23,000 cubic yards),fines(10,000 cubic yards),sorted ore(400 cubic yards),and <br /> barren stockpiles(1,300 cubic yards). If ABA testing indicates that the fines are acid-forming,then <br /> amendment of fines must be conducted real-time(unless another management tool is agreed with the <br /> Division)such that the pile is amended as it is formed to ensure that the NP to AP ratio is not acidic. <br /> The South London Stockpile will be bermed according to Exhibit E Mining Plan which depicts stormwater <br /> berms at the base of certain areas along the toe of the stockpile as shown within Detail 1.
