My numbers are a little different due to the belief that about 1/1000th of the processed material will become concentrate:
BO RIVER
300 Tons per day
150 Days X 300Tons = 45000 Tons
1/1000 of processed =45 tons of concentrate
170 g/Ton X 45 = 7,650 Grams
7 X inshore results = 53,550 Grams of Gold
Converted to troy oz = 1,721 oz of Gold
1721 X 1300 =$ 2,238,174
ZIMMI DISTRICT
300 Tons per day
150 Days x 300 Tons = 45000 tons
2.64 g/ton x 45000 = 142,560 grams of gold
2 X inshore results = 285,120 grams of gold
Converted to troy oz = 9,166 oz of gold
9166 X 1300 = $11,916,867
For a grand total of $ 14,155,041
Plus Diamonds
Plus Crops
Anything else is gravy.
