I have not heard an estimate yet on the containers. I am looking foward to hearing the numbers on the high grade concentrate they have been stock piling for months.
A 3.5x8x20 foot container will hold 21,7727 tons of moist top soil. That is about 48,000 pounds or 20 yards if my math is correct. You can add another 30-50% for the wet black sand and gold. I have had a few margaritas tonite so it may be a good idea to check the math.
