marathon to supply usa govt with uranium?

I understand that the US military use large supercomputers to do 3D simulation testing of nuclear bombs and the resultant collateral damage fallout, as opposed to the old fashioned dig a hole in the ground and explode a real bomb.

Seems to me that Marathon Resources could supply their computer 3D simulation JORC compliant 60 odd thousand tons of uranium (plus more to come) directly to the US military’s computerised 3D nuclear bomb simulators via encrypted satellite communications, and thus save all the cost of drilling, plant, staff and capex costs, or am I missing something obvious here?
