EnviroGold Global Expands IP Portfolio with 20 Patents & Designs, Advancing CleanTech Focus ...

TORONTO, Nov. 07, 2022 (GLOBE NEWSWIRE) -- EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF |FSE: YGK) (“EnviroGold Global” or the “Company“), a Clean Technology Company accelerating the world’s transition to a circular-resource economy, is pleased to announce it has expanded its IP portfolio by acquiring 20 patents and designs (the “CleanTech IP” or the "Technology"). The CleanTech IP is comprised of 13 patents and 7 design patents with active registrations in the United States, Australia, Canada, United Kingdom, Germany & Chile.

EnviroGold Global’s proprietary technology is being applied to the Company’s Hellyer Tailings Project, where independent analysis from the Company’s flowsheet development partner, Core Resources, has demonstrated gold recovery rates >80% and silver recovery rates >90% for total project after-tax free cash flows of US$ 350M ( link ). The application of the Company’s proprietary technology to the Hellyer Tailings is expected result in the production of ~965,000 gold-equivalent ounces over an ~8yr project life through the liberation of precious metals, including gold and silver, and critical metals, including copper, lead and zinc. The Hellyer Tailings resource is well-studied with multiple JORC technical resource reports and an updated NI 43-101 mineral resource estimate (2022) on file.

The CleanTech IP includes patents for iron ore beneficiation, electrochemical oxidation and the removal and destruction of contaminants including cyanide, arsenic, mercury & selenium. The CleanTech IP also includes patents related to the removal of Per- and Polyfluoroalkyl Substances (“PFAS”), from mining & industrial effluents. Commonly referred to as “Forever Chemicals”, PFAS are rapidly emerging as contaminants of significant concern for the global mining industry. with the US Environmental Protection Agency (“EPA”) proposing the designation of two of the most widely used PFAS as hazardous substances under CERCLA or Superfund. The Company expects the CleanTech IP will significantly enhance its metal recovery and environmental remediation capabilities while facilitating future growth into direct lithium extraction (“DLE”), where the Technology has demonstrated significant potential.

Commenting on the IP portfolio expansion, NVRO CTO Brock Hill, said, “The world’s rapidly growing demand for clean energy, advanced technology, expanded infrastructure and investment requires massive quantities of precious and critical materials including gold, silver, lead, copper, zinc, nickel, cobalt and lithium. The clean energy transition alone, which is creating increasing demand for electricity storage and transportation, is expected to require over 3 billion tonnes of additional metals. Concurrently, social pressures and concerns for the environment have made it essential that these materials are produced cleanly and responsibly, while environmental remediation obligations faced by industry are increasing the need for environmental remediation solutions. EnviroGold Global’s core identity is as a CleanTech innovator focused on developing and commercializing IP which can generate substantial profits for shareholders while solving social and environmental challenges. This expansion of EnviroGold Global’s IP portfolio advances our strategy significantly, enhancing the Company’s technical foundations and opening new avenues for the development of high-value solutions for industry and society. It is a privilege to lead EnviroGold Global’s technical development initiatives as we continue to advance our mission of transforming the world’s overabundance of waste into responsibly produced precious and critical materials for the modern, circular economy.”
