Commerce Resources Produces Additional Mixed REC Sample with 22.4% NdPr from the Ashram Deposit, Quebec

May 12, 2022 – Commerce Resources Corp. (TSXv: CCE, FSE: D7H0, OTCQX: CMRZF) (the “Company” or “Commerce”) is pleased to announce that it has produced additional amounts of mixed rare earth carbonate (“mixed REC”) that meets typical rare earth element (“REE”) market specifications, as part of its planned scale-up to larger kilogram quantities.

The sample (55 g) follows the initial quantities of mixed REC sample produced by the Company, announced March 23rd, 2022. The Company is pleased to report the new sample has a neodymium (Nd) and praseodymium (Pr) distribution – i.e. % of Nd+Pr oxide of the total rare earth oxide (“REO”) – of 22.4%, which is significantly higher than the distribution reported by several major global producers, and that of the previous sample produced (21.6% NdPr). Additionally, the mixed REC sample, with a formula of REE2(CO3)3(H2O)8 as determined by XRD, contains 50.9% REO, <0.5 ppm Th, and <0.1 ppm U.

The mixed REC sample (Figure 1) was produced from the Ashram Rare Earth and Fluorspar Deposit using the conventional recovery flowsheet developed at Hazen Research, Inc. in Colorado, USA, which results in high grade monazite concentrate exceeding 40% REO. The monazite concentrate was processed through a sulphuric acid pot digestion (Figure 2), to ‘crack’ the monazite, which was then followed by a water leach to liberate the individual REEs into solution at high recovery (see news release dated September 9th, 2021). The thorium was then selectively removed using solvent extraction (Figure 3) and the REEs subsequently isolated, also using solvent extraction, and precipitated as a mixed REC concentrate, meeting typical market specifications (Figure 1).

In the rare earth industry, a mixed REC concentrate is typically viewed as the initial marketable product in the REE value chain. A mixed REC is readily saleable as it is the most common feedstock to REE solvent extraction facilities globally, which separate the individual REEs and allow for them to be individually refined into marketable products and disseminated throughout downstream value chains.

About the Ashram Deposit

The Ashram Deposit ranks as one of the largest REE (and fluorspar) deposits globally, consisting of a monazite dominated, single mineralized body outcropping at surface, and has a footprint approximately 600 m along strike, over 300 m across, and 600 m deep, remaining open in several directions. The deposit hosts a measured resource of 1.6 million tonnes (Mt) at 1.77% rare earth oxide (REO) and 3.8% F, an indicated resource of 27.7 Mt at 1.90% REO and 2.9% F, and an inferred resource of 219.8 Mt at 1.88% REO and 2.2% F, at a cut-off grade of 1.25% REO (Effective Date July 5th, 2012). Note, mineral resources are not mineral reserves as they do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves.

About Commerce Resources Corp.

Commerce Resources Corp. is a junior mineral resource company focused on the development of the Ashram Rare Earth and Fluorspar Deposit located in Quebec, Canada. The Company is positioning to be one of the lowest cost rare earth producers globally, with a specific focus on being a long-term supplier of mixed rare earth carbonate and/or NdPr oxide to the global market. The Ashram Deposit is characterized by simple rare earth (monazite, bastnaesite, xenotime) and gangue (carbonates) mineralogy, a large tonnage resource at favourable grade, and has demonstrated the production of high-grade (>45% REO) mineral concentrates at high recovery (>70%) in line with active global producers. In addition to being one of the largest rare earth deposits globally, Ashram is also one of the largest fluorspar deposits globally and has the potential to be a long-term supplier to the met-spar and acid-spar markets.
