I think SFMI has erred by dropping a decimal place in the value of silver in ounces/ton on their estimate of revenues in "SFMI revised 2011 Updated History of Mining On War Eagle Mt.", pg. 23, dated 8/16/2011. Instead of 4.7 0z. silver/ton, it should read .483 oz. silver/ton.
They also erred in the number of grams in one ounce of silver and gold used for calculations on the pg. 23 chart. They used 31.4 grams/oz. silver when the correct number is 31.1 grams/oz. silver
If corrected figures for silver are used, then silver revenue is only one tenth what pg. 23 shows, and should be $1,981./day, not $19,639./day silver.
This changes the yearly total of revenue to $ 3,469,440./yr.
