If you look at the operating results of Minefinders for 1st qtr 2010 and convert their fractional silver production to gold equivalent ounces, MFN sold 22,279 gold equivalent ounces. We can say that's close enough to 90K oz per year. MFN market cap = $622 Million Canadian, which is 17x TDC market cap.

So all things (POG, economic conditions) being equal, TDC share price should be $2.80 per oz when Tyhee is selling 90K oz per year.
