It's good news for GXY reduced cash FOB cost from March's USD$453/ton to USD$337/ton (1.39%/1.03% * 337/t = 454/t) due to 35% incresse in feed grade from 1.03% Li2O to 1.39% Li2O. But the Mt Cattlin Project’s ore reserve is 10.7Mt @ 1.15% Li2O. So the average mining cost of the Mt Cattlin project would be around USD$407/ton, plus average royalties and sale cost USD$92/ton, the total cash cost for Gxy's Mt Cattlin project would be around USD$499/ton which is reported as one of the world's lowest cost project.
