# Erdene Expands Mineralization at Zuun Mod Molybedenum-Copper Project Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/erdene-expands-mineralization-at-zuun-mod-molybedenum-copper-project--bc4d6306-970f-4796-a136-5846c702eb4d Original source: https://money.tmx.com/en/quote/ERD/news/5948788222557585/erdene-expands-mineralization-at-zuun-mod-molybedenum-copper-project Publisher: tmx Original announcement: 2026-02-17T12:54:31.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Erdene Resource Development Corporation - Ticker: ERD - Exchange: TSX - Region: southwestern Mongolia - Primary commodity: Molybdenum - Secondary commodities: Copper, Silver, Gold - Document categories: Drill results - Extracted: 2026-09-13 22:47:50 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Erdene Resource Development Corporation announced drill results from its Zuun Mod Molybdenum-Copper Project and Khuvyn Khar Copper Prospect in Mongolia, reporting multiple high-grade intercepts. Drilling at Zuun Mod confirmed continuity and improved grade in near-surface zones, with one hole intersecting 374 metres of 0.066% MoEq. At Khuvyn Khar, a hole returned 65 metres of 0.63% copper and 2.9 g/t silver, including a higher-grade zone. These results will be incorporated into an updated resource model and a Preliminary Economic Assessment targeted for mid-2026. Reasoning: The drill results demonstrate significant expansion and confirmation of high-grade molybdenum and copper mineralization at the Zuun Mod and Khuvyn Khar projects, supporting an upcoming PEA and resource update. The comprehensive QA/QC adds credibility, though the lack of true width disclosure for some intercepts is a minor drawback. The gold results are early-stage and low-grade. - Positive factor: Multiple high-grade intercepts exceeding 0.1% MoEq, including 1.25% Cu and 6.1 g/t Ag over 30m, demonstrate significant mineralization. - Positive factor: Drilling successfully expanded and confirmed continuity of mineralization at both Zuun Mod and Khuvyn Khar, including near-surface and at depth. - Positive factor: The results will be incorporated into an updated resource model and a planned Preliminary Economic Assessment \(PEA\), indicating progress towards development. - Positive factor: Comprehensive QA/QC procedures are disclosed, enhancing confidence in the reported results. - Negative factor: Reported intervals are apparent widths, and true widths require additional study, which may overstate actual thickness. - Negative factor: The gold intercepts at Sundown are low-grade, indicating early-stage exploration with limited economic significance at this stage. Facts used in scoring: 79 ## 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 mentions the use of SGS Laboratory, standards, blanks, field duplicates, and laboratory duplicates, and states that Peter Dalton, P.Geo., is the Qualified Person. Evidence · text > Peter Dalton, P.Geo. \(Nova Scotia\), Senior Geologist for Erdene, is the Qualified Person as that term is defined in National Instrument 43-101 and has reviewed and approved the technical information contained in this news release. All samples have been assayed at SGS Laboratory in Ulaanbaatar, Mongolia. In addition to internal checks by SGS Laboratory, the Company incorporates a QA/QC sample protocol utilizing prepared standards and blanks. All samples undergo combined multi-element ICP-OES \(Inductively coupled plasma optical emission spectroscopy\). Erdene’s drill core sampling protocol consisted of collection of samples in 1 to 2 metre intervals over the entire length of the drill hole, excluding minor post-mineral lithologies and dykes as required. Sample intervals were based on meterage, not geological controls, or mineralization. All drill core was cut in half with a diamond saw, with half of the core placed in sample bags and the remaining half securely retained in core boxes at Erdene’s Bayan Khundii exploration camp. All samples were organized into batches of 30 including a commercially prepared standard, blank and either a field duplicate, consisting of two quarter-core intervals, or a laboratory duplicate. Sample batches were periodically shipped directly to SGS in Ulaanbaatar. **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent. Why it applies: The metal equivalent formula and assumptions \(MoEq% = Mo% + Cu% \* 0.27504, 83% Mo and 81% Cu metallurgical recoveries, Mo price of US$15.4/lb and Cu price of US$4.34/lb\) are clearly disclosed. Evidence · text > MoEq%=Mo% + Cu% \* 0.27504 and assumes 83% Mo and 81% Cu metallurgical recoveries, and based on Mo price of US$15.4/lb and Cu price of US$4.34/lb **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 document explicitly states that reported intervals are apparent thicknesses \(downhole widths\) and that additional study is required to confirm true widths. Evidence · text > Reported intervals are apparent thicknesses, i.e., downhole widths. The Zuun Mod drill hole \(reported in this release\) was dipping at 70 degrees. Additional study is required to confirm true widths. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Hole ZMD-162 was designed to expand on previous mineralization, indicating a step-out drilling objective. Evidence · text > The highest-grade copper mineralization was reported in January, in hole ZMD-162, which was designed to expand on the mineralization intersection in ZMD-121, completed in late 2010. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The drill program included 18 holes testing the upper 150 metres of the Zuun Mod deposit, seeking to improve confidence and continuity of molybdenum mineralization, which is characteristic of infill drilling. Evidence · text > The program included 18 holes testing the upper 150 metres of the Zuun Mod deposit, and one hole extension \(ZMD-98\), seeking to improve confidence and continuity of molybdenum \(“Mo”\) mineralization in the North Racetrack area, at depth. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The intercept of 30m at 1.25% Cu and 6.1 g/t Ag in ZMD-162 is exceptional for a porphyry copper deposit, significantly exceeding the strong grade threshold for copper.

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.
