1.5% is good grades. If above 1% I will be the first to come here and admit I was wrong.. But I know that will not happen. I know what good lithium cores look like from previous experience.
Do yourself a favour and find either AVZ, LTR, LLL PLS whatever it may be and check out their core samples and you will see what a lithium rich pegmatite looks like. Another example AZS, drill results pending and the core samples look awesome.
