Hi @Davy Boy, the weathering is over many millions of years, so it wouldnt matter a great deal, usually the rock chip samples from weathered pegmatites will only identify that lithium is present, drilling will be carried out to give a better idea, the samples taken up to 1.04% are incredible and as a rule will increase, whilst this is normal it is not guaranteed, I like it all, the pure white clay is an indicator of no or very small traces of iron or mica, there is much to like here and if you can go back through anatols posts you will find so much great information, GLTAH
