Calcination, Acid Roasting and Water Leaching of spodumene concentrate (reported October 12, 2021) to produce lithium carbonate

Higher than 99% pure lithium carbonate achieved

Approximately 99% Li2O recovered from impurity removal stages

Test work to commence shortly on a direct lithium hydroxide from spodumene concentrate process

VANCOUVER, British Columbia, Oct. 27, 2021 (GLOBE NEWSWIRE) — United Lithium Corp. (CSE: ULTH; OTC: ULTHF; FWB: 0ULA) (“ULTH” or the “Company”), is pleased to announce results from proprietary lithium purification testwork to produce lithium carbonate (Li2CO3) from spodumene concentrate. Testing produced lithium carbonate with a purity of approximately 99.1% from the initial bench tests. This test program was conducted under the supervision of Dr. Abdul Halim at Process Research Ortech Inc. in Mississauga, Ontario, Canada.

The technical grade of Li2CO3 product and recovery of Li2O from flotation concentrates are considered excellent.

Process Research Ortech Inc. (PRO) was contracted by United Lithium Corp. to develop a sustainable process flow-sheet for the recovery of lithium from a hard rock deposits. The primary lithium mineral to be concentrated is the alumina-silicate spodumene. Spodumene is considered the most important commercial lithium mineral due to its high Li content and favorable processing characteristics. For phase one of the program a lithium rich pegmatite was sourced from Canada for testing.

The success of this program has encouraged United Lithium to continue forward with expanded test work for direct lithium hydroxide production from spodumene concentrate. Test work to date will allow optimization of pilot plant testing, expected to commence early in 2022. The proposed pilot plant will test lithium rich feed materials from a variety of projects, with results expected to be suitable for an economic assessment of a flowsheet to recover Li2CO3 and LiOH from spodumene and petalite feed.

Work to date continues to demonstrate 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. Reagents and water consumption can be minimized by recycling the process streams such as filtrates, washes, evaporated water and crude products to the Li2CO3 precipitation, impurity removal, and water leaching stages.

When additional test work to convert 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. A test program to optimize the calcination and roasting portions of the flowsheet to make them even more environmentally friendly is being designed by the company’s President and CEO Michael Dehn and Dr. Abdul Halim, VP Technology of Process Research Ortech Inc.

”Test work to date has demonstrated that it is possible to modify traditional processes and shortcut lithium carbonate production using innovative out of the box thinking. United Lithium aims to commercialize a sustainable and robust process flow sheet for lithium concentrate production, high grade lithium carbonate and potentially high purity battery grade lithium hydroxide, with the ability to accommodate multiple feed materials with minimal modifications.”, states Michael Dehn, President and CEO of United Lithium. “By making minor improvements in each step of the traditional flowsheet, we believe we can deliver a new lithium flowsheet with distinct economic and environmental benefits”.

The detailed bench test work to develop a flowsheet was conceived and supervised by Dr. Abdul Halim, VP Technology of Process Research Ortech Inc. He has over 15 years of experience in developing and optimizing innovative and sustainable technologies for critical metals including lithium, cobalt, nickel and other base metals, PGMs, gold, germanium and rare earths (REEs) from mined natural resources and recycle 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 Inc. as a VP Technology.

The results confirm the continuity of the deposit and extend the know mineralization laterally, along strike and at depth into the unweathered rock.

LONGUEUIL, Quebec, Dec. 07, 2021 (GLOBE NEWSWIRE) — Reunion Gold Corporation (TSX-V: RGD) (the “Company”) is pleased to report new significant gold intersections, including 2.44 g/t over 46.5 meters, 2.22 g/t over 57 meters and 1.88 g/t over 41.0 meters as part of its ongoing drilling program at the Oko West Project in Guyana. Hole 47 intersected the deepest mineralized interval so far, with 2.22 g/t over 57 meters at approximately 200 meters vertical depth from the surface (Table 1). These new drill results, which consistently show high grades and intersected lengths, clearly demonstrate that gold mineralization continues at depth in unweathered rock. The results also expand the gold mineralization laterally and continue to show the strong mineralization continuity along a “corridor” more than 1.2 km long. Preliminary metallurgical studies outlined below also show encouraging results with gold recoveries ranging between 78% and 98%.

The objective of the current drill campaign is to confirm the vertical and lateral continuity of gold mineralization previously identified in eight “blocks” straddling shear zones over a 3 km long strike length, within a 6 km long soil geochemical anomaly. Diamond drilling (“DD”) has been focused on testing depth extensions into the unweathered rock below 100 m (Figure 2), as well as testing for lateral extensions between the outlined blocks. The reverse circulation (“RC”) rig is testing the edges of exploration blocks and scouting previously untested targets both laterally and along strike. The Company has so far demonstrated continuous gold mineralization in a “corridor” more than 1.2 km long (see Figures 1 and 3) characterized by zones of intense deformation and hydrothermal alteration in sedimentary, granitic, and volcanic rocks. These zones contain widely disseminated gold in microfractures and metric-scale high-grade veins assaying up to several ounces per tonne.

Carlos Bertoni, Interim CEO, stated: “We are very excited by this round of drill results as they continue to demonstrate the impressive continuity of the gold mineralization outlined to date with long intercepts of good grade. The results successfully expand the known deposit both at depth into the unweathered rock, and laterally, between the previously outlined “blocks.” The deposit remains open to expansion in all directions. We have only started drill testing the southern 3 km of the soil geochemical anomalies.”

The Company restarted its drilling activities at the Oko West Project early in November, following a one-month break to finalize the interpretation of the then recent results and to properly plan the current 9,000-meter drill program, and for equipment maintenance. Assay results presented in Table 1 below shows significant intersections from a total of 1,322 meters in eight DD and 834 meters in nine RC holes, with assay results from two DD holes and ten RC holes not yet received.

The Company has now drilled a total of 6,467 meters in 53 DD holes and 7,836 meters in 91 RC holes since the beginning of the drilling program at Oko West in December 2020, with significant assay results reported in press releases on August 12, September 7, and October 7, 2021. The Company will interrupt its field activities at the Oko West Project from December 17, 2021, and restart early in January 2022 and plans to complete this current drill campaign by the end of March 2022.

Metallurgical testing

The Company completed a maiden scoping-level metallurgical test by bottle-roll cyanide leaching eight mineralized samples at the Actlabs laboratory in Georgetown, Guyana. These samples represent weathered and unweathered rocks from trench and drill hole samples in different host rocks. Positive gold recovery results were received using low cyanide (0.5 kg/t) in under 12 hours of leaching. Gold recoveries range between 78% and 98%. These preliminary encouraging results indicate that gravity concentration followed by cyanidation should improve gold recoveries. The Company is preparing a complete metallurgical testing plan for the Oko West mineralized rocks.

Drill result composites, sample collection, assaying and data management

The Company calculates drill results composites with a minimum length of 2 m, a cut-off grade of 0.3 g/t and 2 m maximum length of internal waste. Gold grades are uncapped. True widths are unknown. Complete drilling results and drill hole data are being posted on the Company’s website. Diamond drill samples consist of half of either HQ or NQ core taken continuously at regular intervals averaging 1.4 m, bagged, and labelled at the site core shed. Reverse circulation drill samples are obtained from a rotary splitter attached to a Metzke cyclone, weighed, bagged, and tagged at the drill site. Samples are shipped to the Actlabs certified laboratory in Georgetown, Guyana, respecting the best chain of custody practices. At the laboratory, samples are dried, crushed up to 80% passing 2 mm, riffle split (250 g), and pulverized to 95% passing 105 μm, including cleaner sand. 50 g of pulverized material is fire assayed by atomic absorption (AA). Initial assays with results above 3,000 ppb gold are re-assayed with a gravimetric finish. Certified reference materials and blanks are inserted at 5% of samples shipped to the laboratory. Assay data is subject to QA/QC using acQuire software and management by an independent consultant.
