Ann: Significant Gallium Mineralisation at Caladao Project, page-13

High-grade gallium ore would be > 100g/t - so this is mostly not high grade. Gallium is normally extracted along with aluminium or zinc, and they mention aluminium but without giving it any significance. It's not in with the REE, it's in the over-burden above the REE. So at present it's a potential single product gallium ore. Are there any examples of viable single product gallium ores at these grades? If the market doesn't think the gallium is economic then that would explain the lack of share price reaction.
