Drainage Reconstruction <br /> <br />Refer to Section 3.0 of this annual report. <br /> <br />Contour Ditch Construction <br /> <br />During 2022, Trapper did not construct any contour ditches. <br /> <br />Stock Tank Construction <br /> <br />No new Stock Tanks were constructed during the 2022 field season. Refer to Section 6. <br /> <br /> Stock Tank Reclamation <br /> <br />No Stock Tanks were reclaimed during the 2022 field season. Refer to Section 6. <br /> <br />Developmental Drill Sites <br /> <br />During the 2022 Developmental Drilling season 16 holes were drilled within the permit <br />boundary. Drill holes were completed in the proposed C Pit area and for possible re- <br />development of the west panel A Pit. All applicable developmental drill holes were abandoned <br />per permit section 3.3.2 and will be reclaimed and seeded per section 3.6.3.5 of the permit. Drill <br />hole abandonment typically uses Alternative 2 for sealing of the borehole. <br /> <br />Topsoil Piles <br /> <br />During 2022, Trapper moved the entirety of pile EM1 to pile I20-1 in I Pit. Pile E79-6 was nearly <br />entirely depleted for topsoil laydown preparation in D Pit. The remaining yards in this pile will be <br />retrieved in 2023 and used to reclaim the site of the pile. Piles MH2, WC1, I20-2 and NN20-1 <br />all had additional topsoil added to them from stripping operations in I Pit. Trapper also <br />constructed four new topsoil piles, J22-1, J22-2, J22-3A and J22-3B in J Pit. Refer to Section 5. <br /> <br />Sediment Dams <br /> <br />Sediment pond cleaning was conducted on No-Name #2, in 2022. <br /> <br />1.2.6 Previously Revegetated Acres <br /> <br />The locations and acres for all previously revegetated areas, seeded to perennial species, are <br />presented in Map(s) 1. To date, Trapper has revegetated approximately 4,690.9 acres. Of the <br />total revegetated acres, 3,805.5 reclaimed acres have received final phase III bond release. <br />The phase III total includes 51.6 acres of re-disturbance in D, I and J Pit areas during 2022. <br /> <br />Not shown on Map(s) 1 in this annual report are the areas seeded to temporary perennial mixes <br />that will require final reclamation prior to the end of the project (life of mine). <br /> <br />1.2.7 Re-Disturbed Reclamation Acres <br /> <br />The parcel identification and acres re-disturbed due to mining activities for all previously <br />revegetated areas will be documented here. Table 1.2 shows acres re-disturbed and <br />summarizes the bond release status of each parcel. D, I and J Pit development resulted in 56.9 <br />total acres of re-disturbance in 2022. <br /> <br />GCR 3/23 <br />[DRMS22RPT\22RECtext1-0]
