Sonoran Desert Copper Corporation announced 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. RDL: Reported Detection Limit; G/S: Guideline/Standard (Class II Landfills). Analysis completed by AGAT Laboratories.
