Not that tough a question... given the history of the First Gold effort...
The First Gold folks had already loaded up the leach pit with reprocessed ores from the new mill investors bought... based on the theory that Pegasus hadn't milled the tails they'd left behind finely enough to enable proper extraction...
They sampled the ores before doing the work and projected X amount of gold would be produced when they put the solutions to the ores... but, when they went to collect the gold... it wasn't there ?
Go figure.
Re-sampling of tails is notoriously risky... easily spoofed...
First Gold went broke because of it (in part, as planned)... but, then, what happened to the leaching solutions and any gold they contained after that ?
Easy answer now is that "it's already been done" so there aren't any "tails" left. Relief Canyon has always been a low grade operation, so there never were any high grade ores, much less high grade tails left from the old days... and, the 1980's aren't that far back that the processes in the 1980's couldn't extract what there was to get ?
