Additional testwork is required over a wider range in grade, including additional lower end and mid-range material, to improve the validity of the geometallurgical model as a predictive tool for the LOM plan and metal production forecast. Key points: Additional testwork is required over a wider range in grade, including additional lower end and mid-range material, to improve the validity of the geometallurgical model as a predictive tool for the LOM plan and metal pr; 1.11 Cost Estimate Initial capital expenditure (CAPEX) costs are estimated to be $1,685 M as summarized in Table 1-3; This cash flow results in a project net present value (NPV) of C$3,367 M, with an internal rate of return (IRR) of 25.0% and a payback period of 2.7 years from the start of production; The project is least sensitive to changes in capital costs, with every 1% change in capital cost affecting project NPV by approximately C$18 M; Production Schedule- 9.0 Mtpa 30 3.0 25 2.5 20 2.0 Mined Tonnes (Mt) Au (g/t) 15 1.5 10 1.0 5 0.5 0 0.0 -2 -1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Ph 0 Waste Ph 0 Overburden Ph 1 Mill Feed Ph 1 Waste Ph 1 O; Plant Feed 10.0 5.0 9.0 4.5 8.0 4.0 7.0 3.5 6.0 3.0 Quantity (Mt) Au (g.t) 5.0 2.5 4.0 2.0 3.0 1.5 2.0 1.0 1.0 0.5 0.0 0.0 -2 -1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Pit to Plant Stockpile to Plant Plant Fe.
