Mmm. I've just done a cut and fill volume analysis of Miaree's magnetic field strength (using Geophysics Australia public databases). I get a volume about 1/30th of Atlas's magnetite anomaly at Pardoo.
Oddly enough Pardoo is meant to have a 1-1.5 billion tonne magnetite potential.
On these figures Miaree should hold about 50 million tonnes of magnetite.
Sorry!
I don't hold AGO or RVR.
