The results include a 176.78m intercept of 0.66% CuEq, and step-out drilling is currently underway to target the core of a large MT conductivity anomaly. Reasoning: The drill hole HER-25-25 intersected significant copper-equivalent grades at the margins of a new porphyry system, coinciding with a large geophysical anomaly, suggesting high exploration potential. - Positive factor: discovery of new porphyry margins - Positive factor: strong CuEq grades - Positive factor: large MT conductivity anomaly target - Positive factor: step-out drilling underway - Negative factor: hole stopped by fault zone - Negative factor: apparent width only \(true width not stated\) Facts used in scoring: 13 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The company is conducting step-out drilling \(HER-26-01\) to vector towards the porphyry center. Evidence · text > step-out drilling underway to vector towards the causative porphyry intrusion **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 details MSA Labs' certification \(ISO 17025\) and specific QA/QC protocols including CRMs and blanks. Evidence · text > an ISO 17025 and ISO 9001 certified laboratory **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 states that insufficient data is available to state the true thickness of the mineralized intervals. Evidence · text > insufficient data are available at this time to state the true thickness of the mineralized intervals ## Extracted facts Stored fact records: 13.
