RE: surferjohn"A cube 16 m. on a side contains 4096 cu. m.
4096 cu. m. weighs about 2.7 t/cu. m. or appx 11000. tons at 6 oz/t for 66000 oz."
Sorry to question your calculations once again, but what do you mean by a cube containing 4096 cu.m? All we have have is a drill intercept of 16m, what are the other dimensions that you are assuming?
Sorry for all the questions. I'm a civil engineer by trade and I'm trying to figure out how you arrive at this 4096 cu.m cube. Thanks
