Ann: SGQ: High-Grade Lithium Confirmed at Mt Alexander, page-5

I read it as the samples are mainly on E22/638 which is 25% IGO.
Anyway :

1. the samples are just the outcrop (surface expression) of the underlying reef. That is likely to spread out quit a bit. Think Iceberg.
2. it's going to need a bit of money money and effort to bring the find up to a point where production can start the first stage is drilling. IGO's deep pockets will be tapped to provide that. That can be enhanced by IGO's providing offtake agreements etc.

I think spodumene and/or lepidolite concentrate post DMS (Dense media separation) only get to around 30% Li before further refinement is required. Since IGO part own a hydromet plant(s) in Kiwnana they will be able create a decent profit for all parties. (like the Ni/Co Sulphides refined to battery grade in IGO's future.

The high ground is why I invested in IGO. In fact on the previous (by two) SGQ announcement I bough some SGQ but sold it at a small profit preferring to pursue the Li via IGO.

BTW I'm not sure why the IGO price is so high at present*. I expect it to be in excess of $15 even $15-20 but in say two to three years time.

All IMVHO
* I'm not complaining.
