I've found 2 conflicting articles:
https://www.marketindex.com.au/news/essential-metals-expands-wa-lithium-mine-high-grades-found
This one says anything above 1% is high grade.
https://www.sgs.com/-/media/sgscorp/documents/corporate/brochures/sgs-min-wa109-hard-rock-lithium-processing-en.cdn.en.pdf
This one talks specifically about pegmatites & spodumene. It says Spodumene can have up to 8% lithium content, and that a typical spodumene concentrate would have 6-7% lithium with higher grades being 7.6%.
So I think as far as lithium goes, its a good result, but as far as Spodumene goes its low by comparison.
Article does say that Spodumene is the most important lithium ore material.
Also drilling at Pipeline for nickel.
