Hey Buddy..speaking of wheel barrows..check this out.. If black sand has a specific gravity of 5-11 (say 7.0 ave.) and your wheel barrow holds 35 gallons and the assay results indicate an average of 100 grams of gold per ton (see last PR) then your wheel barrow would weigh 2,045 pounds and have approximately 3.5 ounces of gold in it. Go SGCP.
