Looks good but suggest making the following changes:
Change Great White M&I Resource to 10.1 Mt ( I actually have this updated in my own spreadsheet, but posted an earlier version on ADN threads last night as it was the one I could easily find on my phone )
Use fully-diluted shares to make the number conservative ( see below ), MEPs cash balance on a relative basis is strong so no need to assume further dilution. Numbers would be more conservative with a calculation based on 522M shares.
