1. Productora alone is a 10 year profitable mine at $3.00/lb copper with payback period 4 years (from the Productora PFS). At current copper prices ($4.10/lb) Productora is paid back in like 2.5 years, and with C3 costs around $2.28/lb the cash margins are awesome.
So given current market prices, and even if Cortaderra didnt exist - yes they would be able to transition to mining their Productora open pit mine. In the mean time, they are about to start taking revenue from the local underground outfit mining the lease as we speak.

2. That will be answered in the Pre Feasibility Study scheduled to begin towards the end of the year. It may be answered in the scoping study that is currently being completed.

3. Someone has posted a fundamental company value analysis on the forum somewhere calculating current fair value at 20c per share. That was before the copper movements this week.
