Mineral Reserve estimates follow the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") definitions standards for Mineral Resources and Reserves and have been completed in accordance with the Standards of Disclosure for Mineral Projects as defined by National Instrument 43-101. Reported tonnage and grade figures have been rounded from raw estimates to reflect the relative accuracy of the estimate. Minor variations may occur during the addition of rounded numbers. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The 2019 Resource estimate is based on a 0.5 g/t Au cut-off grade. The Updated 2019 Mineral Resource has an effective date of February 8, 2019 and is constrained by a conceptual $1,500/oz Pit Shell. The Qualified Person for the Kalana Main Resource Estimate is Geoff Booth, FAusIMM, Mining Consulting Manager, Snowden Mining Consultants. The Qualified Person for the Kalanako Estimate is Helen Oliver, FGS, CGeol, Endeavour Mining. The Qualified Person for the Tailings Resource is Ivor Jones FAusIMM, Principal, Denny Jones Pty Ltd. For additional notes relating to the 2019 Resource Estimates, please consult the section below entitled "Kalana Resource Modelling".
