I think SDL can see the likely foot prints for likely iron ore at surface when they do their fly overs of the tenements.
Iron ore at surface or just below surface would change the nutrients for the grasses and plants. The lush green in the areas with good soil would change to a more yellow colour.
I was looking at a satellite picture of the area around Mt Nebeba last week and could see this colour difference like foot print over the Mt Nebeba and other high ground North and West of Mt Nebeba by looking closely. The colour changed from the yellowish/green to deep green between the high ground in the valley's. Other areas of lower ground with out the high hills was dark green right up to the Cameroon border.
