Charles, It looks like the grading for the Doyon mine works out to between .15 and .2 opt. So this implies a processing cost of $30 to $40 per ton. I checked ouy the LLL property in Costa Rica, the Beta Vargas mine. The numbers I am seeing are a grade of 2.28 grams per ton which, if my math is correct, is an opt of .081. Where did you see <.02? They are Also estimating their cost at $250 per ounce which implies processing costs of @$20 per ton. If you hypothetically applied this range of costs to a deposit with a grade of .04 your cost of production would be between $500 and $1000 an ounce, uneconomical. (CM this is just a hypothetical extrapolation for some mental gymnastics, I know the real issue is finding a production technology that will unlock greater yields plus platinum.) Henry
