Here's a partial transcript:

The metallurgical testwork comes from three deposits – Cardinia Hill, Lewis and Helens.

The original work that we did at Helens and Lewis was to try and address an issue that we got relatively low metallurgical testwork results from those deposits when we put it through conventional crush, grind, leach testwork.

And now we’ve converted that to flotation testwork, and got much better results from flotation testwork than we did from the original testwork. So we’ve now applied that flotation testwork regime to Cardinia Hill, and Cardinia Hill got 96.9% recovery from that.

So really good metallurgical testwork results from Cardinia Hill as well as from converting the Helens and Lewis testwork to flotation as well.

So really pleased with that performance.

And that will flow through to more gold production, more utilization of the resource, etc etc.

So multiple benefits.

And preumably, not just to new arisings.

As per the Interpretation and Implications cited above, this flotation testwork surely implies a revision of those "..modifying factors to mining and processing production estimates during the 2019 PFS".

Resulting in a significant increase in the proportion of fresh sulphide ore able to be economically extracted and increased pit design depth, ore supply and estimated economic return retrospectively in the 2019 PFS.

Expand

These results will lead to a revised optimized pit shell design as well which by the end of the September quarter will be accompanied by the upgraded MRE which will include all or most of the new discoveries .

Thank you Professor Graeme Jameson for your wonderful invention all those years ago ( the Jameson Cell ) with a rougher cons regrind circuit once again providing great met results .

Grade and Yield pivotal to success . Very nice !
