I liked that picture too scanspeak! From the side of the container in the immediate background, you can see that the capacity (CUCAP) of that container is 16.5m^3. It looks like they are nearly full, lets say 15m^3 of material. Now this is predominantly 99.65% copper according to the company, and copper has a density of approx 9 tonnes per cubic metre, so if the containers were packed perfectly, they would weigh 15*9 = 135 tonnes.

The company say that these containers weigh 22-25 tonnes. Is there really 80% air in there?
