There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the Production Target itself (or the forecast financial information) will be realised. The proportion of Inferred Mineral Resources underpinning the Life of Mine Production Target is not the determining factor in project viability. The Inferred Mineral Resources do not feature as a significant proportion early in the mine plan and the forecast payback period for the Mandilla Gold Project is less than one year.
