121 Mining Investment London 2018, page-75

I think we need to be a little cautious about the grades in the "car park" the grades the company reported using the hammer mill was ~ 9 g/t the grades JG spoke about would have been from a lad. The gold extracted in the lab would be total gold content and as we all know we are only using gravity recovery at the moment. So while the gold recovered from the hammer mill test is very encouraging, it will depend on how much of the gold in the tailings is locked up in sulphides ( if any ) and will not be recoverable through the plant at the moment.

So while I expect some very good oz to come our way from the tailings via HM4, I believe there will be further gold to recover at a later date. I could be way of, but ever since RC mentioned about sulphides in Cuca, I can't help but to think there will be sulphides in Cascavel as well. Not trying to be a wet blanket at all, but as we all know in mining, nothing is ever easy....
