I sent this to the PASSC a few years ago. They told me that without someone on the ground to survey it, there is no way to know for sure - although it does appear promising.
Have a look: -23.275604,120.1671922

Have a look: -23.275604,120.1671922 No, it does not look promising. It looks like the patch is surface colours is indicating a hill, with other similar circles also marking the round and rounded hills... one on each side, and 5 in a line being the next features south. and south of that.. the Hammersley Range. The hill you found looks to be a feature created by the hard iron bearing rocks all over the Pilbera. This hill is just a dark hard form , rather than the rock which turns red and produces the red silts. eg The area is known for fossilferous iron pisolites. Imagine old waterwaters that became filled with dirt, and iron compounds, for various reasons, and over time that material formed a concretion... so the filled lake or is now a hill that erodes slower than the surrounding plain. Erosion tends to wear off sharp corners faster though, so the hill looks like a hill ^ rather than showing the waterways shape.. although there are similar patches nearby which show the gorge or billabong (river meander) shape.
