"Do you think that any geo worth his salt would be very curious as WHY and where is it coming from.???"

cloncurry,
It is an interesting anomaly, but nothing more that at present - despite the millions spent on it and years of exploration - that's my point. If I was the curious geo responsible I would have have stepped out a lot further and drilled a lot deeper long ago, though with far fewer holes. But I'm not a geo, perhaps there's something I don't understand?

My speculation (and admittedly its little more than that) is that its a waste dump from the original Mary Kathleen mine. Perhaps they found some ore too rich, and hazardous, to process and dumped it here under a thin cover of soil. That would explain why it can be penetrated by bedrock drilling and the original CRA report referred to it as a surface anomaly.

Or perhaps its the remnants of a meteorite?

OK the latter seems unlikely, but you can't rule out either of those possibilities based on work done to date (in my layman's opinion).

Happy to be shown otherwise, as always.
