La Cigarra - gradeI forgot to mentioned about the comment on grade.
The might be able redo La Cigarra model to have as much as a 20% increase in grade.
La Cigarra`s M&I grade is 86.3 g/t silver, which is very good for a (open-pit) bulk tonnage silver deposit - especially when the deposit is well positioned along a 2.4 km mountain range and is predictable and well controlled structurally (with reasonable strip ratio, especially for the grade).
The model changes could push the M&I grade to arouind 100 g/t silver.
