i will sell all the mineral rights of each of these celestial bodies for .02
Granted similar race to the spot thing, if you get their first you can claim it, otherwise you dont get it.

Earths mineral rights have already been taken and are therefor property of the respective person.
This is for reals,  get your mineral rights of ALL THE PLATINUM ON ANY COMET
would you like trillions of gallons of gases?  all yours.   one cheap price.

i bought a three subject notebook just for this guys.
