$69,106,382.16 from one mining operation
II. Diamonds and Gold - Jequitinhonha River Valley Land Bank
Minerals: Gold, Diamonds, Sand (for construction)
Location: Olhos-d'Água and Diamantina , state of Minas Gerais
Area: 26,645 acres The NI 43-101 report describes the existence of mineralized materials amounting to 1,639,200 cubic meters with the following concentrations: 0.16 carats of diamonds per cubic meter and 182 milligrams of gold per cubic meter.
That's roughly 6 cubic meters per diamond carat.
1639200/6 = 273200 carats and I used $200 dollars per carat (your number may vary). So the yield would be $54640000.00
For the gold in the ground.
((1639200 x 182mg)/1000mg/gm)/31.013grams = 9614.387 ounces of gold
9614.387 x 1504.66 dollars per ounce (before costs) = $14,466,382.16.
Total would be 54640000 + 14466382.16 = $69106382.16 in the ground not including inferred in the ground.
