The Company estimates its Ore Reserves and Mineral Resources in accordance with The Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 Edition ("JORC Code"), which governs such disclosures by companies listed on the Australian Securities Exchange. The JORC Code differs in several significant respects from Industry Guide 7 of the US Securities and Exchange Commission (“SEC”), which governs disclosures of mineral reserves in registration statements and reports filed with the SEC. In particular, Industry Guide 7 does not recognise classifications other than Proved and Probable Reserves, and the SEC does not permit mining companies to disclose Mineral Resources in SEC filings. The Company’s fiscal year (‘FY’) is 1 July to 30 June, e.g. FY19 = 1 July 2018 to 30 June 2019. The Company uses Australian dollar presentation currency for reporting purposes. Financial figures are in Australian dollars unless otherwise stated. Several items in this presentation are shown in US dollars to aid comparison. US$ in this presentation converted from previously published A$ results using FX rates used in preparation of published quarterly reports and financial statements as follows: Averages: FY19 = 0.7152, FY18 = 0.7751, FY17 = 0.7539, FY16 = 0.7281, FY15 = 0.8319, FY14 = 0.9178.
