I don't think anyone is expecting fantastic resolution although if the work TG6 is doing comes close to matching the resolution of the BP33 pictures below, and this work shows previously identified pegmatites and where they are estimated to extend then there will be some happy Geo's and shareholders. I suspect this is a technology area where improved cheap timing crystals and computing power are substantially improving what is possible.

If this work identifies some 20-50m+ flat-lying pegmatites it will be money well spent!!

Agreed - its an aid for drilling not a substitute for drilling. BP33 isn't a particularly large pegmatite with a width of up to 40m and averaging 20-30m so the ANT success case isn't one of these 100m interval instances but a pegmatite with dimensions smaller than TG6's exploration target. Despite these modest dimensions it was showing nicely in the ANT seismic work that fleet space did (although somewhat ironically, they used memory stick recovered data!!).

The significant problem that Core lithium have is that there are many dozen barren pegmatites on their tenements. ANT helps them know where to drill for a pegmatite but doesn't help them find pegmatites that are mineralised.

Now if only there was a company and tenement where most of the pegmatites they are finding are mineralised??
