Ann: Metallurgical tests show pathway to reduced processing costs, page-5

Certainly looks like very positive news (from a lay person's perspective, which means the management is always putting the Met/leach test work the priorities whether it's economically viable etc. to be applied to AR3 REE resource). A good opportunity i reckon will be to ask MD the questions (there are quite some in-depth posts and legit doubts here from a few red-hearts and experienced ones re viability so probably a good timing to ask the management those questions) face-to-face/directly as Rick will be presenting at @RR_Stars Conference on the Gold Coast on May 17 (tomorrow) at 11am AEST and will be available at booth No. 3. per their twitter post as well as online.
(unfortunately i can't go and ask questions mainly being not a native speaker as well as a lay-person on REE, though as much as i would like to as they are critical for Ar3's success)
