bruceyg, BHP's report is available for you to read as well.
I have not read all of the information BHP have released, but from the information I have read from BHP, it does not say the scale of the project has changed, nor does it say it is considering another project over Olympic dam.
But if you have information that shows otherwise, then please share with us and post a link.
I would and I'm sure others would appreciate some actual facts that can be substantiated.
There is definitely too much political bias "Truthiness" going on on this thread.
