They may have sunk (and barring that, certainly dampened) the current quarter with a preventable ice fiasco at Endako, but the mere absence of disclosure regarding yet another quarter-destroying foul-up might act as an excellerant underneath the share price.
If production at TC mine progressed as planned in Q1, they will be cycling their low cost production out-the-door as final sales by at least Q2, almost exclusively. [Remember: Q4 production was good, and cash cost was low - - two quarters of that, and that material starts moving out the door - - since they use FIFO, and their higher cost inventory overhang from previous quarters (with its higher costs) sells out first and should be virtually all gone by Q2.]. That means moly profits will perk up, irrespective of price, based on lower production costs alone. That might be enough to give the shares a big jolt, by itself.
On that note, do know that prices for moly oxide FOB North America are higher than what is often mistakenly taken as a proxy of worldwide pricing , that being LME Moly Oxide contract price , which is lower than NA pricing by almost two dollars a pound, in the spot market. This spread has been widening since Jan 1. TC should benefit as they pick up more spot pricing orders that would have gone to their Utah-based competitor, since they've declared force majeure.
Any hint that TC will be earning decent money again (and soon), this stock will quickly retrace the lost ground since Feb.
