Whatever they find it to be it’s certainly got some of the right characteristics to be gold bearing.

I’d suggest having a read of this slide presentation on the Witwatersrand and start looking at what we do and don’t have. [/BCOLOR]

So far we know we have the conglomerate, Constantine sandstone unit which contains chlorite-actinolite rich schists with spinifex textured komatiite and high mg basalt. We know that the Constantine unit (2990 ma) underlies the Mt Roe Basalt (2775 ma) and overlies the Cleaverville (3015 ma) and that the Mallina at a similar age group also lies between these formations. We know that at Egina the gold was found at surface on country marked as Mallina Formation at surface.

We know that carbon leaders are an important marker for the microbial mats which are thought to have aided the deposition of gold. We appear to have that box ticked in sections of the Cleaverville and Constantine?

“The most abundant rock type in the felsic sequence is a medium- to thick-bedded, feldspathic sandstone and siltstone (AG(sfs)). This is a moderately foliated rock showing various degrees of silicification. Graded bedding in an outcrop 4 km northeast of Black Gin Well, indicates that the sequence youngs to the northwest in that area. In thin section, these rocks have a varied composition, but they typically contain subangular clasts (up to 0.5 mm) of plagioclase, K-feldspar, and various fine-grained felsic rocks (Fig. 12).

A bedded felsic sequence north of Black Gin Well also contains interbedded coarse-grained volcaniclastic sandstone and conglomerate (AG(sfc)). These rocks contain a variety of felsic rock clasts, up to 300 mm in size (Fig. 13), which include plagioclase-phyric ?rhyolite–dacite, spherulitic rhyolite, and plagioclase-rich trachytic rock. Much of the sequence is pervasively silicified and there is localized carbonate alteration. A minor rock type in the felsic sequence is carbonaceous siltstone and shale (AG(shg)). These rocks are extensively silicified and recrystallized and are mesoscopically similar to layered chert. The siltstone contains relict clasts of quartz, K-feldspar, and ?plagioclase up to 0.3 mm, in a very fine-grained, recrystallized matrix of white mica, quartz, and feldspars.

The carbonaceous material is mostly concentrated in discrete layers but is also disseminated throughout the rock.”

We know that further north at Egina the Mallina formation bean shaped nuggets were found in what appears to be the same complex as is found on PIO’s ground. We know that at Egina there are elevated U levels consistent with Wits View attachment 837395

Some of us know that Wits style gold comes in a couple of different forms, sometimes fine sometimes coarse.

We know that the Kangan area has been home to previous gold production of both quartz and conglomerate hosted gold over 100 years or so but with apparently limited development on the north side of the structure.

While the Pilbara conglomerate hosted gold story is still largely built upon speculation, as the golden pieces come together it appears that we could well be a significant part of the story.
