-        Up to 8.39% Li2O produced in flotation concentrate testing

-        Up to 70.3% of the Li2O in the tested pegmatite recovered in flotation testing

-        Lithium Carbonate product recovery tests on flotation concentrate results expected to be released shortly

-        Spodumene prices registered an 86% increase in September (FOB Australia) against a backdrop of tight raw material supply and surging chemical prices in China

Vancouver, British Columbia October 12, 2021 – United Lithium Corp. (CSE: ULTH; OTC: ULTHF; FWB: 0ULA) (“ULTH” or the “Company”), is pleased to announce the results from flotation testing of spodumene-rich pegmatite sample materials using an innovative and proprietary flotation technology. This test program was conducted on lithium (Li) bearing pegmatite samples collected from a Canadian source containing 1.4—2.1% Li2O to develop a proprietary process flowsheet that can then be applied to various other spodumene rich ore deposits.  The scope of the program included sample preparation and characterization as well as flotation.

The greatest hard rock concentrations of lithium-containing minerals occur in granitic pegmatites. The most important of these minerals are spodumene (Li2O.Al2O3.4SiO2), petalite (Li2O.Al2O3.8SiO2) and lepidolite (LiF·KF·Al2O3·3SiO2). Among these minerals, spodumene is considered the most important commercial lithium mineral due to its higher Li content and better processing characteristics.

Process Research Ortech (PRO) was contracted by United Lithium Corp. to develop a sustainable process flowsheet for the recovery of lithium from a hard rock deposits. The primary lithium mineral to be concentrated is the alumina-silicate mineral, spodumene. For Phase 1 of the program (making a flotation concentrate) materials from a lithium-rich pegmatite was sourced in Canada for testing.

The QEMSCAN analysis was carried out at Activation Laboratories Ltd. in Ancaster, Ontatrio, Canada on two size fractions of the feed: -200M (21-0165) and +200M (21-0164). The results of the QEMSCAN came after most of the flotation runs were completed. As shown in Table 2, spodumene is the predominant Li bearing mineral present in the feed, and the coarser fraction is enriched in this mineral.

The success of this program using this ”greener” flotation technology encourages United Lithium to continue forward by testing lithium-rich pegmatite material from its 100% owned Barbara Lake Lithium Project in Ontario, Canada, and its 100% owned Bergby Lithium project in Sweden and continue with development of a sustainable flowsheet for lithium recovery. United Lithium also plans to test Li-rich materials that will be collected as part of due diligence programs for projects that may be acquired by the Company in the future.

”We are very pleased with the work completed to date and are now encouraged to test multiple hard rock, dominantly spodumene bearing, lithium deposits. Our ultimate goal is commercializing a sustainable and robust process flow sheet to produce lithium concentrate as well as high grade lithium carbonate that will accommodate multiple sources of feed material with little or no modification to the process”, states Michael Dehn, President and CEO of United Lithium. “Success to date is the result of innovations and tweaks that Dr. Halim has been able to develop without reinventing a totally new process, and by looking at opportunities where energy, reagents, and water can be reduced in the process, and adding tweaks along the way to improve recoveries and recycling of reagents.”

Work to date has successfully demonstrated a “greener” process: lower temperatures, lower chemical needs, shorter processing times versus incumbent technologies point toward the environmental and CO2 impacts of high grade lithium salts production to be substantially reduced. When additional test work in converting the spodumene concentrate into lithium carbonate is completed, a life cycle assessment for this innovative process is planned, and engineering data will be available to support decision making.

Benchmark Minerals reported on October 6, 2021 that “ the mid-September digital auction held by Pilbara Minerals was the latest catalyst in the ongoing spodumene price rally when it received a record-high bid of $2,240/tonne (FOB Australia) for 8,000 dry metric tonnes (dmt) of spodumene concentrate (SC 5.5%), which follows the recent previous record-high price of $1,250/tonne in late July 2021, also achieved at a Pilbara auction.” Theslarge increase in price in a short period demonstrates that shortness of supply of spodumene.

On September 20, 2021 Roskill reported   the price achieved by Pilbara Minerals that “The majority of volume is largely tied up in long term agreements, including shareholder agreements, where prices are based on discrete pricing formulae to allow for price stability and sustainability. Besides shareholder agreements, the majority of volumes are tied up in long-term supply agreements, which were required by financing institutions to provide funding for projects. These agreements leave very little volume available for external parties and smaller converters will be scrambling for raw materials to allow them to partake in a market where prices are continuing to increase.”

The PRO test work flowsheet was conceived and supervised by Dr. Abdul Halim, VP Technology of Process Research Ortech. He has over 15 years of experience in developing and optimizing innovative and sustainable technologies for critical metals including lithium, cobalt, nickel & other base metals, PGMs, gold, germanium and rare earths (REEs) from mined natural resources and recycled materials through bench, pilot, and demonstration plant operations. He has authored more than 50 scientific and technical papers, holds 5 US patents, and has authored a number of book chapters in these areas. He worked at FLSmidth, Salt Lake City, USA, and SGS Lakefield, Canada prior to joining Process Research Ortech as a VP Technology.
