Ann: Gold Extraction Tests from Bulk Samples Recover Gold Buttons, page-72

Thanks Midnight ,
suspect that the other PGMs will leach out with different ion-exchange resin beds.Explains some of the previous appointments .(Dr Willer Pos May 17 2017 announcement)
It will be interesting to see the tenors of the leachate once the gold and silver has been extracted.

Should be plenty of leaches in the jungle.

The big costs of extracting these PGMs is the mining.Just a bit more processing.The rock mining and crushing will already have been done hence the profits on these "by products" will be huge.

With the tonnages that are being envisaged, BBX could also become a significant global producer of these also.
