Sampling at the Union Mine and Union Norte targets returned significant results, including 0.6 m at 91.7 g/t gold and 1.0 m at 1,827 g/t silver. The program also defined three new target areas, with all results reinforcing drill targets for an upcoming Phase 2 drill program. Reasoning: Riverside Resources reported high-grade gold, silver, and base metal assays from Phase 2 field work at its La Union Project, including bonanza grades from channel and selective samples, which validate the project's potential and define new targets for an upcoming drill program. - Positive factor: High-grade gold, silver, and base metal assays - Positive factor: Identification of three new target areas - Positive factor: True width disclosed for channel samples - Positive factor: Comprehensive QA/QC procedures reported - Positive factor: Results reinforce drill targets for upcoming program - Negative factor: Some silver overlimit assays are pending - Negative factor: Sampling is from channels and selective outcrops, not drill core - Negative factor: Cut-off grades for compositing are not explicitly stated Facts used in scoring: 105 ## Classification and evidence **True Width Disclosed** Polarity: positive Definition: Actual thickness perpendicular to structure is stated, not just downhole length. Why it applies: The document explicitly states that 'Widths are true thickness as sampling was done perpendicular and on exposed material for all channel samples in this news release.' Evidence · text > Widths are true thickness as sampling was done perpendicular and on exposed material for all channel samples in this news release. **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 Qualified Person \(Freeman Smith, P.Geo\), the assay laboratory \(ACT Labs\), and specific QA/QC methods including fire assay, ICP/EOS, chain of custody, standards, blanks, and duplicates. Evidence · text > The scientific and technical data contained in this news release pertaining to the Project was reviewed and approved by Freeman Smith, P.Geo, a non-independent qualified person to Riverside Resources Inc., who is responsible for ensuring that the information provided in this news release is accurate and who acts as a "qualified person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects. All widths in this news release are within 90% or more of true actual thickness as these are from exposures where sampling was done perpendicular to the trend of the mineralized unit. Rock samples from the exploration program were shipped to ACT Labs in Zacatecas for preparation and analysis. Gold was analyzed using fire assay techniques. A 45 element ICP/EOS analysis using 4-acid digestion methods was used similar to the earlier assay work on the Project. Samples were maintained in chain of custody being delivered to the laboratory in sealed bags. Standards were inserted into the sample stream by Riverside every 20 samples and blanks inserted every 100 samples. The laboratory also inserts duplicates every 20 samples as an additional check on quality control. The QA/QC was analyzed with a check for any variations in the standards beyond 2 standard deviations and the standards passed. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit.

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.
