Casablanca Mining announced that the United States Patent Office granted a patent for the electro mining technology owned by its indirect majority owned subsidiary. Patents for the electro mining process have previously been issued in Chile, South Africa, and China, and patent applications are pending in Canada, Australia and Brazil.

The electro mining technology subject to the patent revolutionizes copper extraction technology by bypassing nearly all of the traditional copper extraction process, and extracting copper directly from crushed raw material using an electrical and chemical process that allows the copper to diffuse through the raw material and attach to a steel plate submerged in a chemical solution. The patented process is significantly faster, cheaper, and more environmentally friendly than traditional copper extraction.

Mr Zirk Engelbrecht President of Casablanca Mining said "We continue to protect our intellectual property on an international level. Our team is developing innovative mining technologies and will commercialize this electromining technology in a way that will enable copper miners to process copper in increasingly efficient ways. The US patent is another example of the dedication our team has to research and development and better practices in the mining industry."
