AA MW Sorter <br /> V <br /> DBMS(Item#9): It is the Division understanding, the sorting plant requires the material to be screened <br /> and therefore a certain quantity of fines will remain. These fines will contain both mineralized ore and <br /> barren waste material. Please provide an estimated volume (cubic yards)of fines that will be generated <br /> from the Operation. <br /> MW Sorter(Item#9 Response): MineWater expects that the fines are about 25%of the total volume, or <br /> 45,000 cubic yards. These details have been added to Exhibit C. <br /> DRMS(Item#10): Please provide the maximum volume (cubic yard) at any given time of the following <br /> processing stockpiles:crusher feed,sorter feed,fines,sorted ore, and barren stockpiles. <br /> MW Sorter(Item#10 Response): MineWater has estimated a maximum volume size for the following <br /> stages of the process:crusher feed (10 cubic yards),sorter feed (23,000 cubic yards),fines (11,000 cubic <br /> yards), sorted ore (400 cubic yards), and barren stockpiles (1,300 cubic yards). These details have been <br /> added to Exhibit C. <br /> DRMS (Item #11): In accordance with Rule 6.3.3(1)(i), please provide design details and additional <br /> information regarding the stormwater runoff and sediment containment berms located at the base of <br /> each waste rock pile and the southern edge of the processing area. Through discussions with the Applicant <br /> regarding the topography constraints of the Upper and Lower WR Stockpiles at the Central Extension Area, <br /> the Applicant may also propose to utilize alternative measures for storm water and sediment control. <br /> MW Sorter(Item#11 Response): Exhibit E Mining Plan has been updated to include details regarding <br /> stormwater runoff and sediment containment berms located at the base of each waste rock pile and the <br /> southern edge of portions of the South London Stockpile. <br /> DRMS (Item #12): During the August 14, 2023 pre-operational inspection, the Applicant discussed the <br /> plans for storm water controls at the processing area. The site will be graded to the north where storm <br /> collects in a ditch and flows to a small sediment pond in the northeast corner of the area before discharging <br /> into the off-site CDPS Pond. This is currently not discussed in the Exhibit C Mine Plan nor accurately depicted <br /> on the Exhibit E Mine Plan Map. Please revise Exhibit C and E accordingly. <br /> MW Sorter(Item#12 Response): Exhibit C was updated with the following: <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. For the central <br /> portion of the South London Stockpile,the stormwater berm, as shown within Detail 2, will be installed <br /> in a phased approach as the stockpile is removed. <br /> Within the Processing Area, the site will be graded to the north where stormwater collects in a ditch and <br /> flows to a small sediment pond in the northeast corner of the area before discharging into the off-site CDPS <br /> Pond. <br /> These features are included within Exhibit E Mining Plan Map. <br /> DRMS(Item#13): During the August 14, 2023 pre-operational inspection, the Applicant stated that the <br /> construction of additional facilities/processes are needed for the pre-permit and off-site water treatment. <br /> The Applicant mentioned the foundation pad for the ore sorter may be used to contain clarifying units for <br /> 5 1 P a g e <br />
