Minestarters Atlas analysis
Summary
Riverside Resources has commenced a ~1,500-metre Phase 2 diamond drill program at the Union Project in Sonora, Mexico. The program aims to expand previous discoveries and test new targets including CRD and sediment-hosted gold-silver-zinc mineralization.
Reasoning: Announcement of a new phase of drilling at an existing project. While no new drill intercepts are reported, the program is fully funded and targets high-priority areas with advanced geophysical support.
Positive factors
- fully funded program
- multiple mineralization styles (CRD and sediment-hosted)
- advanced geophysical targeting (IP and aeromagnetic)
- high-grade surface samples (5 g/t Au) in Jabali area
Facts used in scoring: 1

Classification and evidence
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: Release mentions a QA/QC program including standards, blanks, and duplicates, and names a Qualified Person.
Evidence · text
“A QA/QC program is continued as part of the sampling procedures for the exploration program.”
Infill Drillingneutral
Confirmatory drilling to raise resource confidence, not new discovery.
Why it applies: The program is described as follow-up to expand on Phase 1 results and orientation.
Evidence · text
“Phase 2 will consist of one to three holes per area, primarily for orientation and to expand on the Phase 1 drilling.”

Positive factors
- exceeds 5 g/t Au threshold
How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
