Yes, time will tell. Meanwhile, I will bet that if Witswatersrand-type conglomerate gold can be mined from the deepest ores of earth in South Africa that they can also be mined profitably at surface in Western Australia too.
It all alludes back to the original suspected source of this Pilbara gold. The Vaalbara continent of our early Earth approximately 3 billion yrs ago or more. Prior to the existance of an oxygen / nitogen atmosphere where the gold contained in a liquid acidic solution encountered a "precipitation even" and was deposited on the Vaalbara conglomerate reefs. Taken from Wikipedia: "Vaalbara was an Archean supercontinent consisting of the Kaapvaal Craton (now located in eastern South Africa) and the Pilbara Craton (now found in north-western Western Australia). E.S. Cheney derived the name from the last four letters of each craton's name. The two cratons consist of crust dating from 2.7 to 3.6 billion yrs, which would make Vaalbara Earth's earliest supercontinent." The Kaapvaal craton in South Africa is marked by dramatic events such as the intrusion of the Bushveld Complex (2.045 billion yrs) and the Vredefort impact event (2.025 billion yrs), and no traces of these events have been found in the Pilbara craton, clearly indicating that the two cratons were separated before 2.05 billion yrs.
Furthermore, geochronological and palaeomagnetic evidence show that the two cratons had a rotational 30° latitudinal separation in the time period of 2.78–2.77 billion yrs ago, which indicates they were no longer joined after 2.8 billion years ago South Africa most likely has over a billion ounces of high grade gold still left in the ground. But as a result of the seismic and plate tectonic events that occurred after the break up of the Vaalbara, the gold reefs were folded back down into the earth's crust. And this gold becomes too deep to mine in most cases, especially since the last 130 yrs on mining has extracted the easy deposits. The low hanging fruit is gone. South Africa now has shafts going down more that 2 miles into the earth's crust chasing high grade gold that is becoming more expensive and dangerous to mine. Human beings cannot function well under the hot temperature so if they still want this gold they will have to come up with other technological solutions. "Flat as a pancake" is a key aspect of NVO's future prospects. It appears the Pilbara craton migrated atop the earth's crust relatively undisturbed over the last few billion layers. Which means that the conglomerate layers are likely to be more horizontal and hopefully close to surface where open pit and conventional shaft mining can still access high grades for decades. Bottom line: If the NW Pilbara does materialize into a Whits 2, there exists the added reality that it may actually have more accessible and minable gold than Whits 1 (even though less total ounces in the ground). That why you have got to love pancakes. This story may go a long way.

That post was mostly dynamite Tx . Now it turns to high-tech in todays world . Anyway ,”keep blasting” as Bruce said to James a long time ago ..... You never know ,someone might arrange a Nobel Prize for yourself one day ....Is there a category for ‘Management ,Life ,The Universe and Everything ‘ :-)
