Hole ZMD-162 intersected 65 metres of 0.63% Cu and 2.9 g/t Ag, including a high-grade interval of 30 metres at 1.25% Cu and 6.1 g/t Ag. Reasoning: The intercept of 1.25% Cu over 30m is a strong result for a porphyry system and confirms the presence of a substantial copper component in the Khuvyn Khar system. - Positive factor: Strong copper grade of 1.25% over 30m - Positive factor: Significant intercept width of 65m - Positive factor: Proximity to existing Zuun Mod deposit - Positive factor: QA/QC protocols disclosed - Negative factor: Apparent width only \(no true width reported\) - Negative factor: Anisotropy and true thickness unconfirmed Facts used in scoring: 4 ## 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: Release mentions use of prepared standards, blanks, and duplicates at SGS Laboratory. Evidence · text > incorporates a QA/QC sample protocol utilizing prepared standards and blanks **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: Reported intervals are stated as downhole apparent widths with no true width provided. Evidence · text > Reported intervals in this release are downhole apparent widths. ## Extracted facts Stored fact records: 4. Some facts used in scoring do not have a stored record. ## Drill Results (4) ### ZMD-162 [Link to this fact](https://atlas-extractions.minestarters.com/news/erdene-intersects-30-metres-of-1-25-copper-in-khuvyn-khar-porphyry-system--dbeea779-a177-4bd9-a5f1-5808d1d90e16#fact-drill-facts-0) Khuvyn Khar · copper #### Identity - Hole ID: ZMD-162 - Project: Khuvyn Khar - Commodity: copper - Region: mongolia - Reported Region: mongolia - Ticker: ERD #### Geometry - Grade: 0.63 - Grade Unit: % - Intercept: 65 m - From: 286 m - To: 351 m - Intercept Depth: 286 m #### Classification - Deposit Type: porphyry - Program: exploration - Sample Type: drill - Group ID: ZMD-162:286-351 - Mining Method: open\_pit #### Location - Loc.

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.
