Vancouver, British Columbia--(Newsfile Corp. - February 27, 2024) - Sonoran Desert Copper Corporation (TSXV: SDCU) ("SDCU'' or the "Company") is pleased to announce that the Company has executed a Memorandum of Understanding (MOU), dated February 26, 2024, with Envirotek Remediation Inc. (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. This includes bioleaching solutions for extracting metal from low grade ores and mining waste streams and polymer encapsulation solutions for the remediation of tailings to aggregates and other industrial end uses. Upon successful completion of the development programs and subject to the required approvals of both Parties, a special purpose vehicle (SPV) will be formed, and a shareholders' agreement will be signed by the Parties for the purpose of commercializing the ETK solutions into 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.

PRIVATE PLACEMENT FINANCING OF UNITS

As previously announced, the Company is offering up to 10,000,000 Units priced at $0.10, for aggregate gross proceeds of up to $1,000,000. Each of the Units will consist of one common share of the Company and one common share purchase warrant, with each warrant being exercisable for an additional common share at an exercise price of $0.25 for 24 months. The Warrants are subject to the right of the Company to accelerate the exercise period if, after the expiration of the 4-month hold, shares of the Company close at or above $0.50 for 10 consecutive trading days. Finders' fees in accordance with TSX Venture Exchange policies may apply to the Financing and all securities issued will be subject to a statutory four-month hold period.
