Slight correction, the pH 1 "colloidal" REE leach actually gives the ionic+colloidal extraction. So 60% = ionic + colloidal. pH 4 gives the ionic REE only which was 20%, so it would be roughly 20% ionic, 40% colloidal, 40% refractory. I think RP's statement "85% of mineralisation can be easily addressed at ambient temperatures and pressures." was referring to the 85% of the mineralisation in the deposit can be leached with ambient conditions, not 85% extraction across the mineralisation. This is supported by their met data released, across their 10 met composites, where ionic+colloidal magREE extraction (pH 1) averaged 60%, not 85%.
