Classic " mining cycle" asserting itself.
Exploration a development drilling over and the long engineering phase ( one of the down cycles ) nearing an end ( capped by the Feasibility Study). That development and engineering phase is dead money time but the production decision that will very likely result from what could be a powerfully robust FS which is now on the horizon and the possibility of a takeout could lift the stock for months.
Mine closures ( and those closures are sticky) are adding to the bull market backdrop in the sector. Runs in this sector tend to be amongst the most powerful in commodities.
