I am not sure how to put this, but what the hell. The worrying aspect of hole 4 too me is the white clay in that area could be formed from the weathering of quartz in the granite (could also be a movement of some sort from somewhere else in the tenements through rain over time etc, but depends on slope of the area to see whether that is a possibility here as well, but I don't know, I am thinking it could be this also so now keeping an open mind certainly on that part of the acreage).
A granite that is predominantly quartz and muscovite (which is generally referrred to as white granite because the different colour of granite relates, in general, to the different mixture of quartz, feldspar and micas in the composition) IMO. Albeit as I said I am learning lithium like everyone else here, but if anyone else has a view please share.
That might explain the lower readings of Li where hole 4 is drilled by the way, when compared to the readings around hole 1 and 3 (see below) where pegmatites have been hit - more stringers and actualpegmatites etc. Just a guess, a wild guess by the way.
Granite itself is a common igneous rock type so its presence is what you want to see because in effect the difference between a pegmatite and granite, because they are both essentially composed of quartz, feldspar and mica, is not that different by the way hence why pegmatites occur with granites as well. With pegmatites they essentially have a crystalistaion process obviously, which in part is caused by trapped water slowing the cooling process which ultimately ends up in the larger coarse crystals been formed, and which are largely absent in grantites explained in this link - https://geology.com/rocks/pegmatite.shtml That is within granites they also have do have very minor amphibole or proxene in it, noting spodumene comes from the proxene family btw - https://www.britannica.com/science/pyroxene
Anyway, time will tell, but am more confident around the area of hole 1 and 3, because of the fact pegamtite stringers and pegmatite has been encountered when relating to guidance on Li readings in the clays (which are higher generally than hole 4 and more interestingly where the rock grabs occurred with high Li20 readings).
This post might explain the theory that GPP is working to, because I was trying to understand myself why they made the statement around 'comfirm variation in the geology of the western margin of the prospect area' as per the Ann.
This post could be completely wrong so time for a VB but thought I would share some thoughts (and obviously treat them with an extreme grain of salt, unless you are frying some eggs as salt is good with eggs, until assays come in and we see some photos. I thought the links might help some follow the blalberings in the Anns, by me and other knowledgeable posters posting here.
