that was a good article thanks for posting.
as an aside to that excalibur mining (exm) is currently drilling 15000m at tennant creek including the Juno and Nobles Nob deposits which historically had a strike of over 12000 g/t this was part of a 30m strike which averaged 680g/t. 1st assay results due soon.
barra will need more results imo, vein v.thin ?
good luck
