Assumption #1: The total ounces mined would only equal today's reserve value of 800K oz. That is, the reserve # will never increase, and not an ounce of non-reserve resource will ever be mined. (this assumption is truly absurd if there is a mine)

Assumption #2: $1500 oz gold (lower than today's price) and total cost to get an ounce out of the ground $1,000 (higher than prefeas). Not absurd, but conservative.

Result: $1500 x 800,000 = $1.2 Billion recovered, at a cost of $1,000 x 800,000 = $800 Million. Profit = $400 Million, which is almost ten times the current market value of Tyhee. At only 800K ounces mined!

There's that A word again.
