Halifax, Nova Scotia–(Newsfile Corp. – September 8, 2021) – Sixth Wave Innovations Inc. (CSE:SIXW)(OTCQB:SIXWF)(FSE: AHUH) (“Sixth Wave”, “SIXW” or the “Company”) is pleased to report results that demonstrate the extraction of gold at high capacity with lower reagent costs. These results were achieved during the successful completion of Phase 1 of the “Green Alternatives for Gold Leaching and Recovery” initiative (the “Green Initative“) undertaken with the Centre Technologique des Résidus Industriels (“CTRI”) and Australian company Mining and Process Solutions (“MPS“). The Company has worked closely with MPS and CTRI for the past 7 months to test the efficacy of Sixth Wave’s IXOS® molecularly imprinted polymer for gold extraction in conjunction with the MPS GlyCat™ process.
IXOS® has previously been proven effective in the extraction of gold from cyanide leach solutions and the completion of Phase 1 of the Green Initiative has demonstrated the ability of IXOS® to extract gold from the pregnant leach solution generated by MPS’ GlyCat™ technology. IXOS® has proven superior to traditional activated carbon technology by demonstrating a higher selectivity for gold relative to other gangue materials, resulting in a higher gold capture than activated carbon.
A major Canadian mining company participating in the research project provided the requisite ore samples. Phase 1 tests used IXOS® with the GlyCat™ technology to determine Glycat’s characteristics and capabilities while confirming IXOS® can adsorb gold from solution with typically an order of magnitude lower cyanide usage.
IXOS® used in combination with the GlyCat™ process achieved outstanding gold recovery and the test results demonstrated a much lower reagent cost. Additionally, the use of IXOS® beads for adsorption during the stirred-batch-reactor testing showed excellent adsorption performance in combination with the glycine catalysed leaching process; achieving recoveries that were on par or slightly higher than recoveries using a more traditional cyanide-leach process.
With the successful completion of Phase 1, Phase 2 testing will focus on meeting Canadian ecotoxicity guidelines. Upon successful completion of Phase 2, Phase 3 testing will involve the design of a processing circuit that validates the performance of IXOS® and GlyCat™ in a full-scale pilot plant at an operating gold mine in Canada. MPS has conducted environmental impact studies for the deployment of the GlyCat™ Process in Australia. The overall project goal is to develop an environmentally friendly flow sheet for the gold mining industry.
“Our collaboration with MPS and CTRI is a major focal point of our mining division activities,” said Sherman McGill, Executive Vice President for Sixth Wave. “We are keenly aware of the need for environmental innovation and safeguards. Phase 1 test results indicate that we can successfully leverage our technology with the benefits of MPS” GlyCat™ Process. The CTRI project is an important initiative for Sixth Wave and our IXOS® high-performance gold extraction products. It is clear that the mining industry is aggressively seeking new and innovative approaches to leach and recover gold as a replacement, in whole or in part, for conventional processes. We believe gold mining companies will have significant interest in learning more about our results and how the technology may benefit their operations.”
“We are very pleased to be in collaboration with Sixth Wave”,
states Mr. Ivor Bryan, Managing Director of MPS.
“Our respective technological approaches can bring tremendous value to prospective customers by significantly cutting cyanide usage along with the associated costs and environmental impact.”
About IXOS® Technology
The foundation of Sixth Wave’s products for the resource sector is its IXOS® advanced extraction media developed using Molecularly Imprinted Polymers (“MIPs“). MIPs contain specifically engineered cavities designed to target and capture molecules of interest, based on molecular geometry and ionic charge. IXOS® media have the ability to attract target molecules to the exclusion of other undesirable elements.
For gold applications, the IXOS® platform is capable of selectively targeting gold while rejecting contaminants such copper, mercury, and other non-target elements potentially contained in a gold-bearing cyanide leach solution. Non-selectivity is a comparative disadvantage of activated carbon, which tends to recover a variety of undesirable ancillary metals that affect gold process economics and purity.
Test results for extraction of gold from cyanide leach solutions have demonstrated the ability to capture elevated quantities of gold as compared to traditional activated carbon. MIPs nanotechnology can be applied to other target elements in addition to gold, including both inorganic and organic elements that require removal from solution.
