Ross Carroll, President and CEO of Commerce, comments: “We are thrilled with the outcomes of our recent drill program at the Eldor Property. The team’s dedication and hard work over the summer have been instrumental in achieving these impressive results. This discovery not only highlights the significant niobium and phosphate potential of the Eldor Property but also adds tremendous value to our already world-class AshramRare Earth and Fluorspar Deposit, just 1.5 km away. We look forward to updating the market on the final drill core assays and unlocking the full potential of this remarkable North American property.

“Niobium is acritical technology element delivering market traction owing to global supply constraints. Niobium is used in many green technologies and is important in advanced manufacturing and structural engineering. Canada, the United States, the European Union and many other countries have added niobium to their list of critical elements. Quebec has a history of being a secure supplier of this important metal, and we are growing in confidence that we can add to the North American supply chain.” Mr. Carroll added.

Patrik Schmidt, Vice President of Exploration of Commerce, comments: “The discovery of a high-grade niobium zone at the Knox Prospect and the best drill results to-date at Miranna are very exciting news. The Eldor Property hosts one of the largest known carbonatite complexes in the world, which hosts rocks that have the potential for significant critical and strategic element endowments, including niobium and tantalum. The tested magnetic-high anomaly defining the Knox Prospect is one of the most prominent on the Property, and these initial results confirm the discovery of yet another high-potential prospect at Eldor.”

Commerce Resources Corp. (TSX-V: CCE) (FSE: D7H0) (OTCQX: CMRZF) is pleased to announce a significant new discovery at its wholly owned Eldor Property in Quebec, Canada, as part of its niobium focused drill program, proximal to the Ashram Rare Earth and Fluorspar Deposit. Assays are reported herein for eight of the total twenty-nine NQ-size diamond drill holes completed during the 2024 summer-fall drill program at the Property.

Inaugural drilling at the previously untested geophysical anomaly referred to as the “Knox Prospect”, has identified substantial high-grade intercepts of niobium (±tantalum & phosphate), including 69.4 m at 0.61% Nb₂O₅ within a wider interval of 96.5 m at 0.51% Nb₂O₅ (EC24-220) (Figure 1 and Table 1). Further to the new discovery made at the Knox Prospect, follow-up drill testing at the Miranna Prospect delivered the best niobium-mineralized intercepts to-date for this prospect, factoring both grade and length of drill hole intercepts – 65.7 m at 0.53% Nb₂O₅, including 35.7 m at 0.67% Nb₂O₅ (EC24-215). This new discovery, coupled with the known mineralization at the Mallard and Miranna Prospects, signals the substantial potential for additional critical element discoveries proximal to the Ashram Rare Earth and Fluorspar Deposit.

The Miranna and Knox niobium (±tantalum & phosphate) Prospects at the Eldor Property are both situated within 2 km of the Company’s Ashram Rare Earth and Fluorspar Deposit. The Ashram Deposit boasts a globally significant rare-earth mineral resource of 73.2 million tonnes (Mt) at 1.89% TREO (total rare-earth oxide) (indicated), and 131.1 Mt at 1.91% TREO (inferred) (see MRE news release dated May 22, 2024). The discovery of a substantial niobium deposit in proximity to Ashram would add to the Company’s existing portfolio of critical element occurrences at the Eldor Property, presenting a compelling opportunity for a joint development scenario with shared infrastructure.

The Knox Prospect presents as a prominent, near-circular magnetic-high signature, comparable in size to the Mallard Prospect, but has previously remained untested owing to a lack of supporting surface evidence such as a well-mineralized boulder train (Figure 2). The applied exploration model which incorporates the knowledge from previous drill programs at Eldor identified Knox to have a high probability to host carbonatite-phoscorite magmatic dikes or sills. These intrusive rocks have high potential to host high-grade niobium (±tantalum & phosphate) mineralization.

Drill hole EC24-220 at Knox successfully returned several high-grade intercepts including 69.4 m at 0.61% Nb₂O₅ within a broad interval of 96.5 m at 0.51% Nb₂O₅, hosted in a carbonatite-phoscorite. The drill intercepts encountered in hole EC24-220 represent the second-best niobium intercept thus far on the Eldor Property, based on a combined grade-width assessment. Although follow-up holes EC24-221 and EC24-222 did not return the high-grade (>0.6% Nb₂O₅) intercepts of hole EC24-220, the presence of a broad (106.0 m) interval of 0.4% Nb₂O₅ in hole EC24-221 including sub-intervals of 14.5 m at 0.60% Nb₂O₅, and 20.5 m at 0.60% Nb₂O₅, along-strike of hole EC24-220 warrants significant additional drilling at Knox to test the full extent of the niobium mineralization at the prospect. The discovery remains open in all directions.

The Company also followed-up on the initial drill testing completed at the Miranna Prospect in 2021, whereas four drill holes designed to test for niobium mineralization along strike. The Miranna Prospect was initially targeted for drill-testing due to strongly mineralized (niobium ± tantalum and phosphate) glacially dispersed boulder train in proximity to the Miranna magnetic anomaly. Drillhole EC21-180 successfully achieved the Company’s objective of identifying an area prospective for follow-up, confirming the presence of high-grade mineralization downhole, including 1.20% Nb₂O₅ over 3.1 m, within a larger interval of 0.72% Nb₂O₅ over 20.4 m (see news release dated December 8^th, 2021).

Follow-up drill holes completed at Miranna during the 2024 drill program were planned adjacent to, and along-strike of EC21-180 to test for continuity of this mineralization. EC24-215 and EC24-216 confirmed continuity of high-grade niobium-mineralization hosted in carbonatite-phoscorite intervals from surface. EC24-215 returned strong grades over wide intervals, including 35.7 m at 0.67% Nb₂O₅ within a wider interval of 65.7 m at 0.53% Nb₂O, and a deeper interval of 21.5 m at 0.62% Nb₂O₅ contained within a broader zone of 80.4 m at 0.43% Nb₂O₅. Additionally, EC24-216 collared in mineralization, returning 20.3 m at 0.62% Nb₂O₅, within a broader interval of 72.4 m at 0.49% Nb₂O₅. These strong results, following-up from drill hole EC21-180, extend the near-surface mineralized trend of the Miranna Prospect in either direction along-strike, reaffirming the potential for additional shallow, high-grade niobium mineralization at Miranna. The mineralization at Miranna remains open in all directions.

Core assay results for thirteen drill holes from the 2024 drill program are still pending (Table 2) and are currently at Activation Laboratories Ltd. located in Ancaster, ON, for preparation and analysis.
