Auxico Resources Canada Inc. announced that the company has signed a technology license agreement with Central America Nickel for the use of CAN's patent-pending ultrasound assisted extraction process for mineral extraction. The UAEx process is a sustainable metallurgical process for the refining of critical minerals using ultrasound technology. The laboratory results demonstrate that when combined with certain acids and used at various frequencies, this ultrasound process breaks up the ore into finer particles in a much quicker time than conventional methods. This reduces the cycle times significantly for the leaching of ores, leading to lower operating and capital costs. As per the Agreement, Auxico has a non-exclusive right to use the UAEx process on ore from any property owned or controlled by Auxico. The term of the agreement is 10 years and can be renewed by both parties. Auxico agrees to pay to CAN a 2% royalty on all revenues derived from any of Auxico's projects that will use the UAEx process. In addition, as part of the agreement, Auxico has agreed to pay to CAN upon signature of the Agreement an advance royalty payment of $500,000. This Agreement follows results on the efficiency of the UAEx process on high-value rare earth samples from Colombia that the Company announced in a previous news release dated May 28, 2021. The recent results provided by CAN show 80%+ recoveries of selected rare earth elements during a 2-hour long leaching time. By using the UAEx process, the level of radioactivity of 994 nanoSieverts per hour (nSv/h) recorded before the 2-hour leach was reduced to a dose rate of 3 nSv/h. As per the Company's recent announcements, Auxico has access to ore from Colombia, Bolivia, Ivory Coast and other jurisdictions that demonstrate high grades of tantalum, niobium, iridium and rare-earth elements. It is Auxico's intention to use the UAEx process on the ore from these deposits in order to separate more efficiently these and other critical minerals from the ore.
