RE:Frontier compared its peersYes Mookster FL lithium grade is very high. But another factor is purity. FL has rare technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3). Needed for specialty glass applications.
In contrast CFR has <0.6% Fe2O3 and PMET and Liontown Kathleen Valley have <0.5% Fe2O3
Resource really is world class.
