## Minestarters Atlas summary

Outcrop Silver &amp; Gold has updated its Santa Ana resource in Colombia, more than doubling its inferred silver tonnes and increasing total contained silver to 41.8 million oz. The update was driven by 130,006 metres of new drilling and the inclusion of the Los Mangos system, though stricter classification criteria moderated the growth in the indicated category.

Reasoning: The resource update shows massive expansion in inferred silver tonnes and total contained metal, driven by significant new drilling and footprint extension, despite a more conservative classification approach.

- Positive factor: Significant inferred silver tonnage growth \(&gt;100%\)

- Positive factor: Contained silver metal growth of ~53%

- Positive factor: Contained gold metal growth of ~45%

- Positive factor: Expansion of resource footprint to include Los Mangos system

- Negative factor: Indicated grade decline vs 2023 estimate

- Negative factor: Stricter classification criteria limiting indicated growth

Facts used in scoring: 12

## Classification and evidence

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: Inferred silver tonnes increased from 966,000 to 2.3 million tonnes.

Evidence · text

> Inferred resources add 2.3 million tonnes

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: Total contained silver grew from 27.2 million oz to 41.8 million oz.

Evidence · text

> contained silver has grown to 41.8 million oz. from 27.2 million oz.

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: The document refers to a 2023 resource, so this is an update, not a maiden resource.

Evidence · text

> than in its 2023 resource

## 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.
