## Minestarters Atlas summary

Orosur Mining has reported promising first drill results from the El Cedro prospect, with hole CED001 returning a 267.4m intercept of 0.65 g/t Au from surface, including high-grade veins. Additionally, the company has completed the Plan of Works \(PTO\) for the Pepas deposit, advancing it into the formal permitting and consultation phase.

Reasoning: First drill results from El Cedro show consistent gold mineralisation and high-grade veins, while the Pepas deposit has reached a key permitting milestone \(PTO completion\).

- Positive factor: consistent gold mineralisation from surface

- Positive factor: mineralisation remains open at depth

- Positive factor: multiple high-grade veins intersected

- Positive factor: completion of Pepas PTO

- Negative factor: premature termination of CED001 due to drilling issues

- Negative factor: lack of local ICP-MS facility requiring international shipping

Facts used in scoring: 5

## 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 industry standard QAQC protocols including blanks, repeats, and CRMs.

Evidence · text

> Industry standard QAQC protocols are put in place with approximately 10% of total submitted samples being blanks, repeats or Certified Reference Materials \(CRMs\).

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results from CED001 are described as testing the flanks of the northern intrusion and intersecting possible down dip extensions.

Evidence · text

> intersect possible down dip extensions of multiple high grade vein systems

## 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.
