Geomega Obtains U.S. Patent Approval for Metallurgical Extraction of Rare Earths and Niobium
June 23 2020 - 2:42PM
Geomega Resources Inc. (“
Geomega” or the
“
Corporation”) (TSX:V.GMA) (OTC: GOMRF), a rare
earth clean technologies developer for mining and recycling, is
very pleased to announce that Geomega’s patent application
US15/578,498 titled, “A system and a method for metallurgical
extraction of rare earth elements and niobium,” has been approved
for granting by the United States Patent and Trademark
Office.
“The grant of this patent acknowledges that our
unique process has been recognized and protected.” said Kiril
Mugerman, President & CEO of Geomega. “The Montviel metallurgy
research executed in 2014 and 2015 (See news releases from April
29, 2015 and May 20, 2015) led to these patents, and set the
framework for how Geomega operates today committed to lowering the
environmental footprint of processes to extract and separate REE,
reagent regeneration and minimizing the amount of effluents and
solid waste that are generated. Geomega is in discussions with
potential partners to use this expertise in metallurgical treatment
of REE to help develop a western supply chain.”.
The technology has been developed by Geomega’s
Chief Technology Officer, Dr. Pouya Hajiani, for the Montviel
deposit and was tested in lab and bench scale. The patents cover an
innovative approach by which Geomega was able to significantly
reduce the reagents usage while producing high recoveries of both
rare earths (REE) and niobium. By using hydrochloric acid (HCl)
regeneration, Geomega demonstrated that a total of 58 kg of
regenerated HCl were to be used per metric ton of ore to extract
REE and Niobium. Furthermore, 91%, 92% and 66% overall recovery
were achieved for Neodymium, Praseodymium and Niobium respectively
(See table below for detailed recoveries). The process was designed
to minimize effluent discharge and to integrate in situ acid and
base production and regeneration in tandem with water recirculation
in a plant powered exclusively by hydroelectricity in Quebec.
“With rare earths supply chains under the
microscope again, efforts are underway by the US and Canadian
Governments to bring critical materials production back to North
America, which would favor Geomega. We believe that the Montviel
rare earth property could become a long-term sustainable solution
for rare earths supply and is therefore evaluating opportunities
with several groups to advance the project.” added Mugerman.
“Coupled together with our ISR technology, Geomega could ultimately
deliver a complete solution of primary mining, recycling and
separation all under one roof.”

About Geomega
(www.geomega.ca)Based in
Boucherville and St-Bruno, Canada, Geomega Resources has developed
a proprietary, environmentally friendly “ISR Technology” that
recycles rare earth elements with focus on the permanent magnet
industry and produces four high demand, high price, rare earth
elements (HHREE – specifically Nd, Pr, Tb, Dy).
The Corporation is advancing towards initial
production from its demonstration plant to supply HHREE’s to North
America and other parts of the world.
Geomega also owns the Montviel rare earth
carbonatite deposit and holds over 16.8M shares, representing
approximately 19% of the issued and outstanding shares of Kintavar
Exploration Inc. (KTR.V), a mineral exploration company that is
advancing the Mitchi stratiform copper project in Quebec.
