RE:Don Mario Stockpilesvalueu1,
Based on Orvana's 2018 guidance for copper production, I think that once the LMZ ore body is exhausted, they will shut down the copper flotation circuit, and produce gold and silver only using the CIL circuit. Cerro Felix is gold only with no copper. Cerro Felix ore should last at least 1-2 years, and then other satellite gold deposits will become the primary ore source for the mill.
The copper oxide ore is an additional revenue source for the future, but probably in 2019 or 2020.
