Ann: Nickel Discovery Extends Over 3 Kilometres, page-128

I am a person with a technical background (geology/geophysics) based in Mali, West Africa. Previously worked in Australia, Asia, US. Currently on gold and lithium.

What interests me in the data presented so far is the magnetic imagery. Pretty clearly, the G88 permit was originally applied for on the basis of geophysics, perhaps with some confirmatory elevated lateritic nickel values, but laterites alone wouldn't account for the magnetic anomaly shown in the recent Ann. Magnetic anomalies require magnetic minerals, and there are a range of those which most commonly accompany structures: obviously magnetite, but as well some mildly magnetic sulphides such as pyrrhotite, not to mention accessory minerals, such as ilmenite, and (perhaps) nickel/cobalt/copper sulphides.

It's difficult to interpret the vertical scale of the broader part of these anomalous magnetic values, but they look to be reasonably wide to me, and, although buried, perhaps not all that far from the surface. The coloured portions a little further north have a suggestion of some E-W intersecting faulting, which could provide secondary targets.

On the assumption that the laterites have developed from something more-or-less directly underneath, I would reckon there is a sporting chance that sulphides underlie the nickel/cobalt laterite values. These surface values often tend to spread from a much narrower base, however, so the width of the current laterite values shouldn't be taken as indicative of what's down below.

Their geophysics contractor should perhaps later be looking at some EM or some kind of reconnaissance IP, in my opinion.
