(ETK). Under the terms of the MOU, SDCU and ETK agree to collaborate jointly on developing and commercializing proprietary ETK solutions for the Mining Industry.

ABOUT ENVIROTEK REMEDIATION

Envirotek Remediation Inc. has invested approximately CA$4.0 million into research and development and related expenditures on remediation solutions for industrial waste streams. These proprietary technologies are industrial waste stream encapsulation and bioleaching solutions. ETK's encapsulation process transforms industrial waste streams like mine tailings materials through proprietary polymerization into disposable and/or reusable materials. These outputs can then be repurposed to aggregates and other industrial end uses. ETK has also developed solutions for the bioleaching of industrial waste streams using microbes. The bacteria are stimulated in the ETK lab to promote more robust growth and utilize the industrial waste streams as a source of food and energy. ETK and SDCU operate and will continue to operate as independent companies, although certain Directors of SDCU are co-founders, investors and principals of ETK.
