$575 is a little different from the $285 (if memory serves) Mr Ginn was maintaining back in aught 5 or 6.

Apples and oranges Silver. Ginn's estimation was for the operating cost/oz onece mine production reaches a steady state. The TD quote was the required operating cost for long-term viability and cash flow. They stated it quite clearly:

"The breakeven life-of-mine gold price is US$575 to allow for recovery of ongoing development capital expenses. The project has positive cash flow from operations at gold prices in excess of US$575."

I'm surprised you couldn't make the distinction.
