The 0.3% was not my comment.Australia's niobium resource is confined to a few deposits, largely as a by-product or co-product of rare earth element or rare earth element-zirconium mineralisation in peralkaline rocks and carbonatites. Examples of these include the Mount Weld carbonatite (Western Australia), the Toongi Trachyte, which is the peralkaline host for the mineralisation of the Dubbo Project (New South Wales) and the Brockman deposit (northern Western Australia).Reported grades in these deposits range from 3100 to 3500 ppm (Toongi, Brockman) to 7400 ppm (Mount Weld).

I'm telling you 0.3% is not economic. It would stand to reason you could find a single operating mine with 0.3% Nb if it were economic wouldn't it?once again a deposit is not a mine.
