Soothsayer, Azure had defined a JORC approved resource statement for Mesa de Plata and Loma Bonita, well before they had acquired Oposura. Oposura came much later only after Teck had decided to explore further at Alacran. MDP and LB were very shallow deposits of and of substantial value. Yes, they would be cheap to mine and to process. They could have been well advanced in mining of theses two deposits by now.

Because of Teck's back-in decision, Azure now have Oposura and Sara Alicia, and additionally Teck may turn up something of value in their current exploration. As for MDP and LB, they will be mined some time in the future.
