They wil bring in Greg Corbett...a recognised expert in the field.
He has written some excellent papers on Cu, Mo, Au style Wall Rock Porphyry Systems...which is what I suspect AQR think they may have discovered here.
If so...and they can nail the high grade feeder breccia...it will be a nice rise.
Below is a sample written on the likely Whitewash style deposit.
Cheers!
Mineralised fluids may exit from high level porphyry Cu-Au intrusion as a number of several forms. Porphyry-style mineralisation formed marginal to the source intrusion are sheeted quartz-sulphide veins which may exploit dilatant fracture systems and migrate significant distances into the wall rocks, and are termed wall rock porphyry systems. For instance the Cadia Hill wall rock porphyry veins display little change over several hundred metres, localised wholly within earlier intrusion wall rocks outside the interpreted source intrusion.
Sheeted veins therefore host and transport mineralisation and provide a structural grain which must be considered during drill testing. Although the transitional relationship of the wall rock porphyry to low sulphidation epithermal mineralisation commonly provides higher Au contents relative to Cu, wall rock porphyry systems tend to be large but display low metal grades (Gaby Au-Cu, Ecuador, some Maricunga belt Au systems, Chile and Whitewash porphyry Mo Rawbelle, Australia), and so only represent favoured exploration targets in settings of good logistics or close to other higher Cu-Au grade mineralisaiton (i.e. Ridgeway adjacent to Cadia Hill)."
