## Minestarters Atlas summary

Riverside Resources has launched its Phase 2 exploration program at the La Union Project in Sonora, Mexico, funded by Questcorp. The program includes geological mapping, geochemistry, and an expanded aeromagnetic drone survey to target CRD and sediment-hosted gold mineralization.

Reasoning: The announcement details the launch of a new exploration phase and the consolidation of land holdings, building on a previous discovery, but does not report new assay results.

- Positive factor: Commencement of Phase 2 exploration program

- Positive factor: Fully funded program via Questcorp

- Positive factor: Expansion of geophysical survey

- Positive factor: Consolidation of Famosa mineral concessions

Facts used in scoring: 1

## Classification and evidence

**Nearology Play**

Polarity: neutral

Story-specific tag

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

Why it applies: The program targets areas near the Luis Hill discovery and Union Mine.

Evidence · text

> Building directly on our Phase 1 results, including the high-grade channel sampling at Union Mine and the new sediment-hosted gold discovery at Luis Hill

#### Tags used in scoring

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: qaqc\_disclosed is not 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

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: the fact restates a prior release

## 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.
