IMO... If Teck finds a commercial porphyry at Alacran then all is sweet... however I think there is zero chance they will just walk away if it turns out it is not big enough.... instead, Teck will spend the full $10m and then sell their 51%... Alacran is worth about $100m on the known discoveries ...
For AZS .... it all hinges on Teck finding good Cu for a SP rise in the short term.. which would be nice to then do a CR to fund Oposura. Failing that ... Teck will be around for at least another 3 years, so AZS getting on with Oposura is the sensible thing to do.
AZS is about to become a small zinc/lead producer with a moderately commercial mine [which will keep the Co going and probably can at least achieve self-funding status], Sara Alicia is a promising extra. If Teck finds something good then AZS will rerate significantly.
