Ann: Initial metallurgical tests Generate Positive Results, page-298

Yes, but KDR cannot separate quartz (or whatever it is) and spodumene "quite readily", as evidenced by the initial metallurgical testing that showed a heavy fraction assaying less than 3% Li2O. Finer grinding will likely be required, and that may or may not work. To say it's a "non-issue" is nonsense. It absolutely is an issue, one that may ultimately be resolved, but until then, a big red flag.
