• These are Met results from Caralue Bluff. These clay hosts are similar sandy loam clays but with a higher degree of topsoil. Note the targeted minerals. Also note they used chlorides not sulphides and the use of salts for catalytic separation. Not saying VMS will have the same results but gives an overall picture if the Coy can replicate this these results a re-rate is on the cards

• Recoveries of up to 86% TREO achieved in leaching trials undertaken by METS Engineering.
• Recoveries of up to 88% were achieved for the MREOs (Nd, Pr, Dy, Tb).
• Test work indicates a high chloride environment is required to liberate REEs from the clay host material.
• These results suggest that the bulk of the REEs should be extractable and not bound within the lattice structure of the clay particles or in resistive minerals such as zircon or monazite.
• Hydrochloric acid was used to create a high chloride environment. Further test work will involve the substitution of common table salt, or NaCl, to reduce acid costs.
