The results confirm broad, near-surface rare earth mineralization with a pooled average grade of 3,497 ppm TREO, with 93% of sampled intervals exceeding the 1,000 ppm TREO resource cut-off grade. These results support the existing geological model and will contribute to ongoing Feasibility Study work and future Mineral Resource classification. Reasoning: Initial assay results from the Feasibility Study drilling program confirm broad, near-surface, and continuous rare earth mineralization with high grades significantly above the resource cut-off, de-risking the project and supporting future resource classification and mine planning. - Positive factor: Broad, near-surface, continuous mineralization confirmed - Positive factor: High grades significantly above resource cut-off - Positive factor: Feasibility Study drilling de-risks project - Positive factor: Strong QA/QC and JORC compliance - Negative factor: True width not known for reported intervals - Negative factor: Results from remaining 12 holes pending Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 48 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release explicitly states 'Certified, QA/QC-verified assay results from the first six HQ core holes' and mentions 'ALS Global' as the laboratory, along with 'standards, blanks and duplicate companion assays' as methods. Evidence · text > Certified, QA/QC-verified assay results from the first six HQ core holes of the 2026 Feasibility Study drilling program confirm broad, near-surface rare earth mineralization at the Cowboy State Mine, Red Mountain, with a pooled average grade of 3,497 ppm TREO \(median 3,879 ppm\) and a maximum single-sample assay of 9,084 ppm TREO over a 3.02 m interval in HC26-RM051. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The document clearly states the compositing rules: 'Composited using sample-length-weighted averaging of certified assays meeting a 1,000 ppm TREO cut-off' and 'Internal dilution of up to 2.0 m of sub-cut-off material is allowed'. Evidence · text > Composited using sample-length-weighted averaging of certified assays meeting a 1,000 ppm TREO cut-off — the same cut-off grade basis the Company applies to the current Cowboy State Mine Mineral Resource \(ASX release, 19 November 2025\). Internal dilution of up to 2.0 m of sub-cut-off material is allowed within an interval; minimum reportable interval length is 3.0 m. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The release explicitly states that 'All reported intervals are downhole lengths; true width is not known for these holes'. Evidence · text > All reported intervals are downhole lengths; true width is not known for these holes \(see Appendix A, Section 2, "Relationship between mineralisation widths and intercept lengths"\). **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The drilling program is described as 'Feasibility Study drilling' intended to 'increase geological confidence and support future Mineral Resource classification and subsequent mine-planning studies', which aligns with infill drilling objectives. Evidence · text > These holes are intended to increase geological confidence and support future Mineral Resource classification and subsequent mine-planning studies. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Hole HC26-RM056 returned 191.11m at 3951 ppm TREO, yielding a grade-thickness product of 754995 ppm·m, which is exceptional compared to the 300000 ppm·m threshold.

Why it applies: proximity is offered as the value premise: "HIGHLIGHTS First certified assay results received from the 2026 Feasibility Study drilling program at the Cowboy State M" ### HC26-RM056 [Link to this fact](https://atlas-staging.minestarters.com/news/american-rare-earths-reports-strong-initial-assay-results-from-2026-feasibility--0677d244-3ba7-4993-9b9b-66bb44a07aa1#fact-drill-facts-46) Halleck Creek Rare Earths · rare\_earths #### Identity - Hole ID: HC26-RM056 - Project: Halleck Creek Rare Earths - Commodity: rare\_earths - Region: wyoming - Reported Region: wyoming - Ticker: ARR #### Geometry - Grade: 3570 - Grade Unit: ppm - Intercept: 191.11 m - From: 8.84 m - To: 199.95 m - Hole Depth: 199.95 m - Intercept Depth: 8.84 m #### Classification - Program: resource - Sample Type: drill - Group ID: HC26-RM056:8.84-199.95 - Mining Method: open\_pit #### QA/QC - Laboratory: ALS Global - QA/QC Disclosed: Yes - QP Signed: Yes - QA/QC Methods: standards, blanks, duplicates #### Compositing - Cutoff Grade: 1000 - Cutoff Unit: ppm TREO - Dilution Disclosed: Yes - Max Dilution: 2 m #### Review - Needs Review: No - Interp.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
