mining topography. The grade, slope and aspect of the reclaimed parcels and constructed drainage <br /> were comparable and consistent to the approved post mining topography as discussed above. <br /> The E Pit parcels comprise a topsoil location and an access road. As there was no excavation of these <br /> areas approximate original contour was spot checked in the E Pit parcels utilizing an Apple Ipad <br /> loaded with the M12 and M1 and M2 maps and the online ArcGIS mapping application. This <br /> allowed comparing and verifying that elevation contours between the maps and the elevation <br /> information from ArcGIS as we walked along this area tracking our location. Given that DRMS is <br /> confident in the elevations recorded in the D & I pit parcels collected from the drone demonstrating <br /> that the M1 and M2 maps are accurate, we are therefore confident the topography for the E Pit parcels <br /> is accurate and complies with the M12 post mine topography maps. <br /> Drainage Reconstruction <br /> In general, each of the SL25 bond release parcels has a northwest aspect with positive drainage <br /> established. Runoff from each parcel flows into drainage channels and then into sedimentation ponds <br /> prior to water discharging from the site. One reconstructed channel was included within the bond <br /> release block as per Map 1. <br /> o Constructed drainage in parcel DAB23 reports to No Name Pond system. <br /> o The channel appeared functional, stable and no problems were noted at the time of the <br /> inspection. <br /> During the bond release inspection conducted on 21 May 2024,the following observations were made. <br /> At the time of the inspection ponds, dams and pond slopes were in good functioning order with <br /> adequate sediment storage capacity. Erosional features and sediment transport were evaluated during <br /> the inspection. A number of erosional features were identified over the course of the inspection. Rills <br /> were present along west and north facing hill slopes in D Pit. Erosional features such as downcutting, <br /> side slope rilling and rock movement were observed. Erosion control structures were noted in the D <br /> Pit channel. The drainage and associated structures appeared to function adequately with the exception <br /> of a couple of compromised check dams and areas of downcutting where repairs will be required to <br /> establish additional stability in the longitudinal profile of the channel. A dozer basin in the D Pit <br /> drainage had filled with runoff, performing its function. Reconstructed drainage in D Pit as shown in <br /> the photos below appeared to have an appropriate gradient and check dam spacing. General <br /> observations were made, and it appeared that drainages meet the specifications in Trapper's permit <br /> with respect to depth, width and side slopes. Concentration of side slop riling is noted in the Photo 6. <br /> Although minor erosional features were noted during the inspection, in general, erosion is not a <br /> problem in the SL25 bond release parcels. The erosional features were brought to the attention of the <br /> operator and subsequently repaired. <br /> Permit Number C1981010 Prepared by: R.Reilley <br /> SL25 Page 17 of 21 <br />
