Drill hole YAR-45 intercepted 399.9 metres of continuous gold-copper mineralization from surface, grading 0.45 g/t AuEq. These results confirm the scale and continuity of the porphyry system and validate the updated 3D geological model, with additional assays pending for three more holes. Reasoning: Initial drill results from YAR-45 confirm a very wide, continuous gold-copper porphyry-style mineralization from surface, validating the geological model and indicating significant exploration upside. While gold grades are moderate to strong for a porphyry, copper grades are consistently weak. The metal equivalent calculation uses an assumed 100% recovery, which reduces confidence in the AuEq figures. - Positive factor: wide\_intercept - Positive factor: from\_surface - Positive factor: confirms\_geological\_model - Positive factor: true\_width\_estimated - Positive factor: qaqc\_disclosed - Positive factor: compositing\_transparent - Positive factor: nearology\_play - Negative factor: metal\_equivalent\_assumptions\_not\_fully\_disclosed - Negative factor: low\_copper\_grade Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 20 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: True width is estimated to be approximately 50% of downhole interval length. Evidence · text > True width is estimated to be approximately 50% of downhole interval length based on current geological interpretation of sub-vertical P-1 intrusive phase contact orientations. **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 mentions a quality assurance and quality control program, including certified labs and specific methods. Evidence · text > GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core samples, including pulp duplicates, mineralized standards and blank samples for every 20 samples; coarse duplicates for every 100 samples and field duplicates for every 50 samples. **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: Cut-off grade and maximum internal dilution rules are clearly stated for the reported interval. Evidence · text > Cut-off grade applied for the entire drill hole composite interval \(from surface to 399.9 m EOH\) is 0.10 g/t AuEq with a maximum internal dilution of 5.0 consecutive metres. The additional composite intercepts are reported above a cut-off grade of 0.30 g/t AuEq with a maximum internal dilution of 3.0 consecutive metres. **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Why it applies: Metal equivalent grade reported with an assumed 100% metallurgical recovery, which is not a realistic economic assumption. Evidence · text > Metallurgical recoveries are assumed at 100% for the purpose of conceptual equivalence pending definitive metallurgical test work; actual recoveries may be lower. **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The project is highlighted for its proximity to existing operations and infrastructure in the Mid Cauca belt. Evidence · text > Located in the Mid Cauca belt in proximity to existing operations and supported by highway and power infrastructure, Yarumalito offers significant exploration upside. ## Extracted facts Stored fact records: 20.

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.
