VANCOUVER, BC / ACCESSWIRE / September 9, 2021 / Commerce Resources Corp. (TSXV:CCE)(FSE:D7H0)(OTCQX:CMRZF) (the "Company" or "Commerce") is pleased to provide an update on the progress of its metallurgical program to produce samples of mixed rare earth carbonate ("REC") concentrate to satisfy several requests by global processors. As part of this program, continued bench-scale flowsheet development, ahead of scale-up and bulk processing, has resulted in the highest rare earth element ("REE") recoveries to date into the combined high-grade monazite mineral concentrate1 as well as into the subsequent sulphation crack water-leach liquor phase (i.e., the pregnant leach solution or "PLS"). Highlights include:

  • Monazite mineral concentrate1 grade ofapproximately 40% rare earth oxide ("REO") at 82% recovery and 3.2% mass pull (recovery and mass pull with reference to unprocessed whole rock).
  • Recoveries of 98% Nd, 98% Pr, 95% Tb, and 90% Dy into the PLS (with reference to the mineral concentrate1).
  • Combined overall NdPr recovery of approximately 78% into the PLS (with reference to unprocessed whole rock).

The flowsheet for the Ashram REE/ Fluorspar Deposit, developed by Hazen Research, uses conventional unit processes to produce a high-grade rare earth mineral (monazite) concentrate1 that is comparable to active global hard-rock REE producers. Specifically, the Ashram flowsheet utilizes a flotation - HCl leach - magnetic separation process approach to achieve high-grade (>40% REO) monazite concentrates1 at high recovery comparable to active global producers.

In the current work, flotation concentrate produced from the 2015 pilot plant operation was used as feed to the subsequent HCl leach and magnetic separation stages, which were completed at bench scale and resulted in monazite concentrate1 grades of approximately 40% REO at 82% overall recovery. The monazite concentrate1 was then mixed (in ~50 g batches) with concentrated sulphuric acid (H2SO4) and heated to ~220°C in a stirred pot over a ~3-hour period to convert the contained REEs into soluble rare earth sulphates (i.e., the ‘sulphation crack'), which were then dissolved in a water leach to bring the REEs into solution (i.e., the ‘PLS'). The recent test work resulted in the highest recoveries of REEs achieved to date in the sulphuric acid - water leach stage, at 98% for NdPr, as well as the highest overall recoveries achieved to date from unprocessed rock into the PLS, at approximately 78% NdPr.

All major hard rock REE mines globally produce mineral concentrates of at least 35-40% REO, which are then placed into solution and processed downstream into marketable products. Such high grades of mineral concentrate considerably reduce the downstream processing cost and risk through lower reagent use, fewer deleterious elements entering solution, and a smaller hydromet plant requirement by comparison. With respect to the Ashram Deposit, test work has now demonstrated that >80% of the REEs in the unprocessed deposit material can be effectively concentrated (i.e., recovered) into just 3-4% of the original mass, resulting in a significant upgrade factor of over 21 times the original head grade. In addition, the recent work has now demonstrated that 98% of the NdPr contained in this concentrate can be put into solution for downstream recovery. These results are also a strong improvement on the 90-95% REE recoveries into solution achieved in prior test programs.

Company President, Chris Grove comments, "The ongoing work on the Ashram flowsheet has demonstrated that very high-grade monazite concentrates1 at high recoveries have been produced, and there is still room for improvement. Moreover, the prior bench-scale work has demonstrated that producing high-grade monazite concentrates1 at high REE recoveries is repeatable, and now, the current test program has demonstrated that high REE recoveries into solution at the sulphuric acid water-leach stage, are also repeatable. Our metallurgical results to date continue to solidify our belief in Ashram as a potential low-cost leader for mixed REC / NdPr supply to the global market."

In the next steps of the process flowsheet the leach liquor produced from the sulphuric acid water-leach stage will be treated by solvent extraction ("SX") to reject thorium followed by SX to purify and concentrate the REEs. A mixed REC, high in NdPr, will then be precipitated from the SX strip liquor. This test work is currently being completed on the bench scale and in parallel to the scale-up of the sulphuric acid pot digestion stage from 50 g batches to 2.5 kg batches. The test work will continue to scale up until approximately 2.5 kg of on-spec mixed REC is produced.

  1. Concentrate refers to the recovered REE minerals into the magnetic fraction of the magnetic separation stage (~70% of the overall REEs) as well as the REEs that have been precipitated and recovered from the HCl leach liquor fraction (~12% of the overall REEs). Collectively, the combined concentrate accounts for >80% overall REE recovery through this stage, which is then fed together into the sulphation crack stage.

About Condor Gold plc:

Condor Gold plc was admitted to AIM in May 2006 and dual listed on the TSX in January 2018. The Company is a gold exploration and development company with a focus on Nicaragua.

In August 2018, the Company announced that the Ministry of the Environment in Nicaragua had granted the Environmental Permit ("EP") for the development, construction and operation of a processing plant with capacity to process up to 2,800 tonnes per day at its wholly-owned La India gold project ("La India Project"). The EP is considered the master permit for mining operations in Nicaragua.

La India Project contains a Mineral Resource of 9,850 Kt at 3.6 g/t gold for 1.14 M oz gold in the Indicated category and 8,479 Kt at 4.3 g/t gold for 1.18 M oz gold in the Inferred category. A gold price of $1,500/oz and a cut-off grade of 0.5 g/t and 2.0 g/t gold were assumed for open pit and underground resources, respectively. A cut-off grade of 1.5 g/t gold was furthermore applied within a part of the Inferred Resource. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources will be converted to Mineral Reserves.

Environmental Permits were granted in April and May 2020 for the Mestiza and America open pits respectively, both located close to La India. The Mestiza open pit hosts 92 Kt at a grade of 12.1 g/t gold (36,000 oz contained gold) in the Indicated Mineral Resource category and 341 Kt at a grade of 7.7 g/t gold (85,000 oz contained gold) in the Inferred Mineral Resource category. The America open pit hosts 114 Kt at a grade of 8.1 g/t gold (30,000 oz) in the Indicated Mineral Resource category and 677 Kt at a grade of 3.1 g/t gold (67,000 oz) in the Inferred Mineral Resource category. Following the permitting of the Mestiza and America open pits, together with the La India open pit Condor has 1.12 M oz gold open pit Mineral Resources permitted for extraction.
