I wonder how representative of anything these samples are at all. By selecting post mined material and predominately quartz , isn’t that biasing the sample completely ?
yes, there is some gold present. No doubt there.
but what proportion of a mined tonne is the quartz vein ?
This is nothing like a drill sample , which is x g/t over y metres, giving some average grade.
Maybe I’m missing something here, but it seems a pretty thin reason for the share price to nearly double ( not that I’m complaining)
if anyone can enlighten me, I’d be grateful.
