ORF Technologies

Overview

  • Portfolio of patents related to mineral extraction
  • Intellectual property was developed over 50 years at a  cost in excess of $20 million
  • The science team will continue to operate under ORF Technologies
  • ORF provides a suite of technologies which will compliment and work alongside the licensing agreement with MetaLeach™
  • The ORF technology suite can support Temas’ internal La Blache Project development as well as unrelated third-party mining projects

Advantages

  • Significantly reduces capital and processing costs (30-50%) and improves recoveries in complex deposits
  • Allows for production of metal or high value product on-site
  • Greatly enhances the mine gate economics compared to conventional concentrators
  • The technologies are especially suitable for high-acid-consuming carbonate (oxide) hosted ores
  • Environmentally friendly and reduces carbon footprint when compared to conventional processing methods
  • Targeting base metals that are essential for the supply of raw materials for the electric vehicle revolution, energy generation and storage technologies
  • Aligned with ESG (Environmental, Social & Governance) policies

Application to Nickel

"Temas is aligning itself with strategic partners who are pursuing a greener and more cost-effective means of processing their ore. With our nickel leaching options from MetaLeach™ and ORF and the current market demand for nickel, we expect to have a busy year in just this one commodity."

Michael Dehn , CEO of Temas Resources

"Wherever you are in the world, please mine more nickel… Tesla will give you a giant contract for a long period of time, if you mine nickel efficiently and in an environmentally sensitive way."

Elon Musk, Tesla CEO said during a Tesla quarterly conference call in July 2020
