Ann: Wiluna Open Pit Mining Commences, page-63

I think you're right CashedUpBogun. Even though things look good on paper, there's nothing more certain than uncertainty. The Matilda geotech issues experienced in the first half of FY18 painfully demonstrated how quickly things can go pear-shaped.

On paper, the ASX announcement from 02/05/18 was reasonably positive with some testwork commentary confirming both the oxide & transitional ores could be processed through the CIL plant, instead of the transitional ores having to go through a refurbished sulphide plant (future) as indicated in the Expansion PFS. Hopefully the anticipated recoveries from the combined oxide & transitional ores will be exceeded.
