RE:Wyloo/ROF metals will be mining more than nickel Good luck... If Black Thor is never going to be an open pit mine, then they may be able to get half of it from underground mining if they're lucky. Black Horse and the new "Valhalla" target are at sufficient depth to consider an all underground proposal with their massive widths. Black Bird is a bit fractured and spotty, but al least logical for consideration as a potential underground project.
