Haven't had a good enough look at all of the tenements surrounding. I have complete trust in the team to choose the best ground, and I'll take a deeper dive once they've made their pick(s). Any guesses I make are probably wrong
But, there are some that are not really even worth looking at, and just a couple with potential for the goods. Licenses covered in sand/alluvium probably won't get picked up by the team. Why would they go digging for blind targets under significant cover when there's hundreds of outcrops sticking out of the exposed country rock, all over the place. They'll want more of those to test at depth. The pegmatites of the Cape Cross-Uis belt are presumably formed from the anatexis of local metasediment lithologies, specifically of the Amis River formation, aka Zerrisenne group.
These lithologies are fairly easily distinguishable from a topographic view of this section of the belt. Basically we want land within the red, with pegmatitic looking outcrops visible on satellite imagery. The bigger the better.
From studies such as this we know that the Karlowa area is the sweet spot for spod mineralisation. Further north/northeast at Uis, pressures and temps enabled a more stable environment for petalite formation. On the other side, further south/southwest from Karlowa towards the Strathmore swarm, it's the same deal. Our current two tenements are seemingly right in this goldilocks zone of metamorphic grade.
The below map outlines the spodumene sweet spot south of the green lines. Again, outside of here there is only really evidence of petalite dominated pegmatite. The blue outline and shaded area represent the Amis River formation metasediments, and the unshaded circles within that are the rough locations of the Red/Grey granites.
Post #:67302042 gives a little bit of detail on EPL 7470 and it's potential, which is where I reckon they're doing their due diligence and "assessment" at the moment. It lines up best with the strike of known outcropping and subsurface mineralisation in the area, and Askari has included the intrusions on 7470 in their "interpreted mineralised structure" from their recent update, running from the Uis mine through both B1/C1 (Karlowa 1 and 2), and current drilling targets. It is also adjacent to the part of 7345 where the team are finding relatively wide, spod rich pegmatite (on surface). Acquiring EPL 7470 would complete our own little lithium triangle, totalling ~500km2, and I reckon the team would be pretty stoked with those landholdings going forward.
There are some decent sized intrusions on the northern licenses that GoldBug mentioned earlier. In theory they should be petalite, but you never know.
Also Andrada reckon they're having some luck over at ML 133 (Nai-nais pegmatites) with the whole Li suite, petalite/spod/lepidolite. Probably not a priority for Askari, unless somehow our tenements turn up nothing and we need to look in different lithologies. But everywhere else in Namibia, apart from right where we are, seems to be just petalite or lepidolite dominant.
