RE: Barrier to takeover The market cap is 400 million for 75% of the mine, so for 100% is would be about 530 millon so about 850 million or a bit less Enterprise Value.
Costs are high on a trailing basic, are costs high with full production, no. The mine produced copper for less than $2 in the past the high quarter was 3rd Q, but that was with substantial shutdown time and mine upgrades being included in cash costs. IMO the costs are not high, unless you are looking at Q3. Cash costs should be evaluated on a reasonable basis, ie. with full or current product and minus extraordinary mine maintenance.
