Vancouver, BC, Canada, September 28, 2020 – CASCADERO COPPER CORPORATION (the "Company"), announces that the US Patent for Recovery of Cesium from Epithermal Mineral Deposits has been granted. The United States Patent Office has published US Patent 10,738,370 (issue date August 11, 2020) entitled "Recovery of Cesium from Epithermal Mineral Deposits" with the Company as assignee.

This patent protects the process developed by the joint team of inventors working on the metallurgical development of the Taron cesium project. The patent describes an acid leaching technology followed by cesium recovery as an alum (cesium, aluminum sulfate precipitate) and refining of the alum to produce cesium hydroxide. The cesium hydroxide product can then be converted to cesium salts such as cesium formate by reaction with formic acid.  Cesium formate is used as a key component of high density brines used to safely control the extreme pressures encountered in oil and gas drilling.

Cascadero Copper acknowledges and thanks the inventors of the process: Dr. Mohammad Mokmeli and Dr. David Dreisinger of the University of British Columbia and advisors to Cascadero and Dr. David Trueman and Dr. Bruce Downing, world authorities on cesium geology and exploration and the late Mr. Bill McWilliam, formerly the CEO of Company.

The now patented cesium recovery process is expected to form the basis for processing of the Taron deposit, subject to further development, engineering and cost studies.

The Taron cesium project is in north-western Argentina, in the southern part of the Ocahaqui Basin, approximately 160KM northwest of the city of Salta.
