## Minestarters Atlas summary

Riverside Resources has commenced its Phase 2 diamond drill program at the Union Project in Sonora, Mexico, in partnership with Questcorp Mining. The ~1,500-metre program targets both sediment-hosted gold and carbonate-hosted replacement \(CRD\) gold-silver-zinc mineralization across five key target areas.

Reasoning: The announcement marks the start of a significant, fully funded Phase 2 drilling program targeting both sediment-hosted and CRD mineralization styles across multiple high-priority areas.

- Positive factor: commencement of phase 2 drilling

- Positive factor: fully funded program

- Positive factor: multiple target areas

- Positive factor: advanced geophysical targeting

#### Tags used in scoring

**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: qaqc\_disclosed is true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "It begins with follow-up at the Union Mine, where prior drilling resolved key stratigraphic and orientation questions, a"

## 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.
