The campaign intersected near-surface gold-equivalent mineralization and base metals, confirming the continuity of interpreted feeder structures. Reasoning: Positive near-surface gold-equivalent intercepts at Union Norte confirm structural continuity, supported by robust QA/QC disclosure. - Positive factor: near-surface mineralization - Positive factor: continuity of feeder structure - Positive factor: QA/QC disclosed - Positive factor: expansion of exploration footprint - Negative factor: true width unknown - Negative factor: drilling complications in some holes Facts used in scoring: 4 ## Classification and evidence No classification tags are available. ## Extracted facts Stored fact records: 4. Some facts used in scoring do not have a stored record. ## Drill Results (4) ### UND26-015 [Link to this fact](https://atlas-extractions.minestarters.com/news/riverside-resources-intersects-near-surface-gold-and-base-metal-mineralization-a--4f6463c7-c172-418d-9851-845bd80629a2#fact-drill-facts-0) Union Norte · gold #### Identity - Hole ID: UND26-015 - Project: Union Norte - Commodity: gold - Region: mexico - Reported Region: mexico - Ticker: RRI #### Geometry - Grade: 0.45 - Grade Unit: g/t - Intercept: 14.6 m - From: 1 m - To: 15.6 m - Hole Depth: 69.6 m - Intercept Depth: 1 m #### Classification - Program: exploration - Sample Type: drill - Group ID: UND26-015:1-15.6 - Mining Method: unknown #### Location - Easting: 376169 - Northing: 3347610 - Elevation: 400 m - Azimuth: 320 ° - Dip: -70 ° - 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.
