We maintain our BUY rating and
35p/sh price target based on 0.6x NAV8%. We think the upcoming pilot plant campaign could be a major
catalyst for Rainbow with excellent risk reward: If Rainbow de-risks CIX-CIC as a separation methodology,
the gypsum stacks could be a large addressable opportunity, a bottom cost-quartile source of rare earths
(at surface, previously treated, in existing industrial sites), and with Rainbow the early mover. While critics
understandably point to the fact that solvent extraction is currently the industry standard REE separation
method, we like Rainbow’s approach: building the pilot plant, focus on execution, and let the results speak
for themselves.
Phalaborwa update: MRE upgrades 77% to M&I, pilot plant commissioning on track for 2Q23
Rainbow released a Phalaborwa (South Africa) project update. An updated JORC MRE sees total 30.4Mt
at 0.44% TREO, of which 23.4Mt or 77% is in M&I categories against the 4Q22 30.7MT at 0.43% TREO
inferred resource. Additional drilling is planned to evaluate density at depth of the stacks as advised by
US-based gypsum experts, Ardaman and Associates (a Tetra Tech company). The pilot plant is on track for
2Q23 commissioning. Design and fabrication work on the front end (crack and leach) has commenced by
Mintek (Johannesburg). The back end continuous ion-exchange (CIX) / continuous ion chromatography
(CIC) units have been delivered to K-Tech in Lakeland, Florida for setup and testing
