AA <br /> MW Sorter <br /> 'V <br /> areas. Exhibit L has been updated to list all buildings, power lines, and buried pipelines that exist within <br /> and up to 200'of the designated areas. <br /> EXHIBIT C—Mining Plan(Rule 6.3.3) <br /> DRMS (Item#6): Exhibit C discusses that there are existing buildings on the permitted site that will be <br /> utilized in the operation and that temporary structures("zircon-type"steel containers)may be brought to <br /> the site. Additionally, as observed during the August 14, 2023 pre-operational inspection, the Central <br /> Extension and Sorting Plant Area is located within a disturbance associated with the historic London Mine <br /> and current water treatment activities. Please review the definition of"affected lands"outlined in Rule <br /> 1.1(4):and confirm all mining activities will remain within the affected lands boundary. Please also discuss <br /> how the permit boundary will be clearly delineated pursuant to Rule 3.1.12(2)to prevent off-site impacts <br /> from occurring at the Central Extension and Sorting Plant Area where a pre-permit disturbance exists on <br /> the other side of the permit boundary. <br /> MWSorter(Item#6 Response): Marking boundaries is an important aspect of this project given the slope, <br /> irregular boundary, and onsite equipment operators. Offsite excursions of equipment and <br /> sloughing/rolling material must be avoided. Therefore,the extents of the affected lands boundaries will <br /> be clearly marked with poles, placed rocks, and/or clearly marked signage to limit mining activities to <br /> those approved designated areas. Also, a designed stormwater management plan (SWMP) berm, plus <br /> on-site training of the equipment operators about the importance of working within the designated <br /> boundaries, will be maintained throughout the project. <br /> DRMS(Item#7): Exhibit C lacks specific details or estimations regarding quantities of materials that will <br /> be processed. Please provide the estimated volume of material(cubic yards)that will be removed from <br /> each of the three waste rock areas(South London Stockpile Area and the Upper WR Stockpile and Lower <br /> WR Stockpile at the Central Extension and Sorting Plant Area). Please provide how much is expected to <br /> leave the site as ore for off-site milling and how much barren material will remain on-site. <br /> MW Sorter(Item#7 Response): Exhibit C Mining Plan has been updated with the following information: <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 stockpile <br /> at the Central/Sorting Plant area. MineWater expects to remove 40,000 cubic yards of ore for off-site <br /> milling,and to replace 140,000 cubic yards on-site at the South London Stockpile Area. <br /> DRMS (Item #8): Based on discussions with the Applicant during the August 14, 2023 pre-operational <br /> inspection, Exhibit C and Exhibit E Mine Plan Map need to be updated to describe and depict the entire <br /> processing plan including but not limited to the crusher feed stockpile, crusher, radial stacker,sorter feed <br /> stockpile,fines stockpile,sorting facility,sorted ore and barren stockpiles,and any other facility to be used. <br /> Appropriate designs and details need to be provided for all structures which are existing or and proposed <br /> to be constructed as a part of the operation. <br /> MW Sorter(Item#8 Response): Exhibit E Mining Plan Map has been updated with footprints showing <br /> rough locations for the crushing area,fines,course ore,ore sorter, product,and insert waste. All of these <br /> activities occur within the designated Processing Area. The map provides relative locations of all of these <br /> activities as they are subject to change after the start of the project. <br /> 4 1 P a g e <br />
