Historic drill results?  Are you referring to the report about a report written before current reporting standings were adapted and by a consultant with limited academic credentials, a property staked by BG as he dumped at least one other claim in the area already outlined by JB (possibly more an ego bolstering more than a scientific one)?

While I don't have the formal credentials for saying so with any authority whatsoever, I can't see RRC claims being renewed, nor will they be taken up by anyone else when abandoned.

...just my guesses.  Use your own judgment.
