I haven't checked lately but presumably BHP still have leases just south of Colluli so that's a measure of how comfortable they were in that part of world - at least at time they made that investment.

You'd think it would be a real fillip for Eretrean's if a company of BHP's stature & size invested there - and it's potential impact on drawing other investors in.

That carrot might be such as to draw concessions from Eretrean's.

But please don't invest on basis of above dream.
