Current market cap is $750 M, expected valuation of copper production at 60 kt is around $1.3B add 10 % for production upside and maybe some more for exploration wins before production starts and the share price should be around 60 cents at commissioning (assuming copper price around $3.20/lb).
This is an engineer's thoughts and as you know with engineers they have no economic insight and would design a perfect world if it wasn't for money...
