## Minestarters Atlas 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 factor: fully funded program

- Positive factor: multiple mineralization styles \(CRD and sediment-hosted\)

- Positive factor: advanced geophysical targeting \(IP and aeromagnetic\)

- Positive factor: high-grade surface samples \(5 g/t Au\) in Jabali area

Facts used in scoring: 1

## Classification and evidence

**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 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 Drilling**

Polarity: neutral

Definition: 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.

## 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.
