SIXTH WAVE successfully completed the Green Alternatives for Gold Recovery Project with CTRI (https://reseaucctt.ca/en/centers/ctri), Mining and Process Solutions (Australia) and a global top ten mining company.

Noteworthy Results Reported by the CTRI Program Manager:

• IXOS^® Molecularly Imprinted Polymer Beads with GlyCat™
• The only “green alternative” for gold recovery to cyanidation in view of the ore, methods, and conditions researched by CTRI
• Recover gold with 90% less cyanide usage than conventional cyanidation
• IXOS^® recovery averaged 95% of “recoverable” gold
• No breakage of IXOS^® beads was identified with visual inspection
• Stripping of beads resulted in 100% metal removal and analyses at CTRI, Sixth Wave and MPS Laboratories were equivalent
• • • Strip was completed in under 2 hrs, at 60° C and with no pressure confirming substantially reduced energy requirements for IXOS^®
  • Gold mass balance confirmed all performance results based on ore head grade, leach efficiency, and gold recovery by IXOS^®
• Cyanide destruction using ozone effectively removes all reagents from the leachate and other methods are under consideration
• “Non-Toxic” ecotoxicity test recorded no daphnia or rainbow trout deaths
• GlyCat™ primary lixiviant is recyclable and a less oxidizing destruction method
• Residual glycine is confirmed as non-toxic indicating any traces of glycine is non-toxic
• IXOS^®-In-Leach (IIL) Technology continues to show profound successes

IXOS^® has proven effective in the extraction of gold from cyanide leach solutions and the completion of Phase 1-2 of the Green Initiative has demonstrated the ability of IXOS^® to extract gold from the pregnant leach solution generated by MPS’ GlyCat™ technology. IXOS^® is superior to traditional activated carbon technology and demonstrates a higher selectivity for gold relative to other gangue materials, resulting in a higher gold capture than activated carbon.
