Update specifics This part in the update was of particular interest regarding MK:
Malku Khota Pre-feasibility level engineering work in progress focused on optimization and production level expansion opportunities with an updated Economic Assessment study targeted for release Q2-2012.
(emphasis added)
Last year's PEA was already targeting annual production of just over 10.5 m ozs of silver over the life of the mine (13.2m ozs in first 5 years), so an increase to production should make for even better economics. For them to mention production expansion it must be big enough to make a notable difference. At the mid-case, every 1m ozs more of production puts approx $20m of annual cash flow on the books in the first 5 years. At the Recent price case, each 1m ozs more of annual production is good for approx $30m in additional cashflow per year over the first 5 years. They could easily pop cashflow up by $40m-$100m depending on silver pricing and how much more they want to produce per year.
