SUCCESSFUL REMEDIATION TESTING RESULTS ON BRAZIL COPPER SLAG TAILINGS

Vancouver, B.C.: Sonoran Desert Copper Corporation (“SDCU'' or the “ Company”) ( TSXV: SDCU) is

pleased to announce that the Company and its mine tailings solutions partner, Envirotek Remediation Inc.

(ETK) have successfully concluded the first testing on a mine tailings sample from a large repository of

copper slag tailings in Brazil. The proprietary ETK polymer process was developed to remediate mine

tailings to landfill material or aggregates and other industrial end use materials.

Based on this successful test , the two companies will now form a special purpose vehicle (SPV), and a

shareholders' agreement will be signed by the Parties for the purpose of commercializing the ETK

solutions into the Mining Industry. The results of the ETK Remediation Procedure for the 20 Metal Toxic

Characteristic Leaching Procedure (TCLP) analysis are all below the reported detection limit (RDL) or

Guideline/Standards (G/S) for Canadian Class II Landfills. (Table 1)

“Our waste treatment sequesters the toxic elements of mining tailings during the polymerization process

and transforms the tailings into dry materials that will no longer produce a harmful leachate, as verified

by the TCLP analysis of the resulting materials,” stated Maria Conejo, CTO for ETK.
