BNR's highest rock sample is ~8%. However it's also relative to how coarse the pegmatite crystals are - if its extremely coarse, then spodumene will take up more % of the whole rock resulting in a higher Li % assay. See image below where at my guess, the single spodumene crystal is 6-8cm long.
What's interesting about surface expression of pegmatites is that they're usually weathered/oxidised to the point where the Li% expression is actually reduced - which is why with a lot of drill core results, companies will state if its fresh or weathered.
At the end of the day, we won't know whats down there until its drilled however it does look quite positive in general.
