RAU has an exclusive option on Mt. Carbine, not ARU.
So Garyrm1973, presumably you made a typo when you posted:
"If Aru does decided to go ahead with the purchase on Mt Carbine the company should move quickly to producer. Investors would throw alot of cash in to get the project moving. After all it was producing and looks like it is in a position to quickly move back to full scale mining...."
