Ann: Primary Nickel and Copper Sulphides Confirmed at Mt Ridley, page-45

No - the analogy is that they are all deep mafic crustal intrusion complexes on the margins of Archaean Cratons. There is another major province in Scandinavia they can reference. Voisey is the biggest so remains the reference. Lonesome Nova-Bollinger is about 1/3 the size I think. Don't quote me though - I haven't touched a rock over 50 million years old for a long time.

Obviously at the moment Nova-Bollinger is a stand-alone. And obviously zillions of punters coins are being spent to find out if it remains that way or not. FWIW - the Ni:Cu in sampling of early aircore was averaging around 4:1, peaking at 2:1 if I remember rightly. It was that geochem signature that highlighted the potential to the Sirius exploration team, and the WA Govt agreed, helping fund the discovery hole.
