This little snippet from Aegis-

Brightstar Gold Project: BrightStar Gold Project has a newly upgraded JORC resource of 1,010,000oz. A feasibility study is well underway and expected to be completed after a toll treating process route is evaluated. The study was expanded to include the successful drilling of the company’s best intercept to date of 22m @ 28.6g/t gold and the design of a 200,000tpa treatment plant. Recent exploration success at Zeta has added significant new ounces, with potential for more upside.

If they go with this option eg. 200,000 tpa with the lead off deposit being of the higher grade say 4gt if all went smothly and recovery was high.
200,000T times 4gt 800,000gm =28,219 0z p.a

28,219 oz times AU price 800per oz=22,575,200 less cost or
28,219oz times $100(margin) per oz =2.82m p.a
hopefully the margin is higher than that.

please correct me if wrong
