I was actually reading into this company presentation last night and what I couldn’t put my head around is how they came up with these numbers? If anyone understands there grades in % please let us potential investors know. It will be much appreciated. The way I see it PPM when wants to convert to % of li’ the typical formula is to divide by 10,000. That means their best grades are somewhere in .30% of Li20. How can they say that riyolite ride is 5,000ppm? That just doesn’t make sense to me. It’s easily 15000ppm for averge grades there if going by there numbers. Something doesn’t feel right with me of their presentation. It might be my lack of knowledge and I apologise in advance if that’s the case.
