Hmm undercover ET more smoke

phosphate surface grades same as Wonarah - Tick
ironstone 250m x 150m outcrop 50% Fe (read not so undercover redox boundary) - Tick

Significantly, this massive ironstone outcrop covers an area of at least 250 by 150m (Figures 4 & 5) and displays
consistent anomalous results for a number of critical elements including phosphorus(P), molybdenum
(Mo), bismuth, iron (Fe), sulphur (S), tin (Sn) and stibnite (Sb)...

Whilst undertaking the phosphate reconnaissance fieldwork, Inca staff discovered a previously
unknown outcrop of massively altered limestone/sediments which had essentially been converted to
an ironstone through hydrothermal activity. Remnant bedding was observed in some of the altered
rocks, where they had not been completely obliterated and converted to massive ironstone.
The area where these ironstones were discovered is covered by loose sand and these rocks had
recently been brought to the surface by the station owner who had put a ripper through the ground
when he recently installed a water tank and related pipework to surrounding stock water troughs.

It seems like we're not the only ones digging up East Tennant massive ironstones near Barkly, here's KRR's 2020 and follow up 2023 reports...
