According to Texalta, who are doing similar exploration close to the Beetaloo, Pacific is a subsidiary of Rio Tinto

CALGARY, ALBERTA--(Marketwire - Feb. 11, 2008) - TEXALTA PETROLEUM LTD. (TSX VENTURE:TEX.A) is pleased to announce that an initial 200 kilometre seismic program on Permits 103 and 104 in the Georgina Basin, N.T., Australia has been mapped out and that work should commence in May 2008 subject to crew availability. The company has instructed its representative based in Darwin, N.T., to obtain the necessary clearances for sacred sites and the environment.

Since the Permits were granted in November 2006 Texalta's team of geophysical consultants has been reprocessing and interpreting the existing 750 kilometres of seismic data which was shot over the period 1988 to 1992 by Pacific Oil & Gas Pty Ltd., the oil and gas arm of the mining company Rio Tinto PLC.

It's a dead end after that. Rio Tinto is a huge corporation. They probably just bought them out.

On November 8, 2007, rival mining company BHP Billiton announced it was seeking to purchase Rio Tinto Group in an all share deal. This offer was rejected by the board of Rio Tinto as it "significantly undervalues" the company. Another attempt by BHP Billiton for a hostile takeover valuing it at US$147 billion was rejected on the same grounds.
