Correction: A2 equal to a cube 21.5 meters on each sideThat's worth a billion bucks.
165,000,000 lbs = 74,842,741 kg
At a specific gravity for pitchblende of 10.75, each cubic meter weighs 10,750 kg. Heavy stuff.
74,842,741 kg / 10,750 kg/m3 = 6,962 m3
The high grade A2 zone is equal in size to a cube 21.5 meters per side. It's kind of like a very large living room, or perhaps a small bar.
