Mr. Graham Roberts <br /> Page 2 of 5 <br /> 26 July 2020 <br /> associated with H Pit and any update to the reclamation bond would be addressed at the time of <br /> the PR, (PR11). Once the H seam is designated for mining, the total mining limit appears to total <br /> 71.3 acres. This may represent a potential increase in volume of material to be moved. <br /> 1. Please indicate on a map or explain in text where the Hseam overburden will be placed or <br /> stored for placement. <br /> Trapper Response: H-Seam overburden removed from the highwall area of the current LPit cut <br /> 18 will be placed in the spoil benches west of the LPit cut in the same manner as the current <br /> spoils awaiting regrade. The material will need to be removed from the highwall crest to attain <br /> the currently permitted PMT for L-Pit. <br /> DBMS: 21 July 2022 <br /> Trapper's response is adequate. <br /> 2. Please demonstrate that the reclamation costs for Hseam overburden removal and stripping <br /> have been accounted for in previous permitting actions. <br /> Trapper Response: As demonstrated in the attached Figure 1 and discussed verbally on May <br /> l7th the material proposed to be removed on the highwall of LPit will need to be removed to <br /> attain the currently approved PMT. These costs would be calculated in the PR09 worst cast <br /> bonding scenario as regrade costs for LPit.No new stripping is currently proposed in the LPit <br /> area with this proposed overburden removal. <br /> DBMS: 21 July 2022 <br /> Trapper's response is adequate. <br /> DRMS notes from conversations with Trapper Mine staff, that stripping is planned in J Pit in <br /> 2022. Depending on when and how much stripping is planned for J Pit, there may be an update <br /> to the reclamation cost estimate required with the I Pit expansion. DRMS also notes that J Pit <br /> 2022 pit limits are indicated on the worst case bonding map (M6),but not on the M 1 OB map <br /> depicting stripping and reclaim activities. <br /> DRMS compared the stripping maps M10 B Topsoil Stripping and Reclaim for TR130 and <br /> PRIO, noting that stripping for the J pit comprising approximately 388.8 acres has not occurred. <br /> It appears that the M IOB map submitted with TR 130 is erroneous as it depicts proposed <br /> stripping and reclaim in the J pit for 2020, 2021 and 2022. DRMS understands that no stripping <br /> has yet occurred in the J Pit as of May 2022. Therefore,the map does not accurately depict what <br /> is currently on the ground in the J Pit. The map depicts stripping in 2022 occurring in portions of <br /> the I Pit Middle, I Pit West and J Pit West comprising approximately 18.5 acres. <br /> 2 <br />
