## Minestarters Atlas summary

Orosur Mining Inc. announced mixed drill results from its Anzá Project in Colombia, focusing on the Pepas West area. While several holes returned no significant gold mineralization, others yielded strong intercepts, including 2.65m at 3.14 g/t Au and 2.05m at 3.46 g/t Au. The company also reported high-grade surface samples up to 79.6 g/t Au, suggesting significant potential for strike extension of the newly discovered Pepas West zone.

Reasoning: The announcement presents mixed drill results from the Pepas West area, including several barren holes, but also some strong gold intercepts and the discovery of a new mineralized zone with high-grade surface samples, indicating potential for strike extension. The project's overall progress and robust QA/QC add confidence.

- Positive factor: Discovery of a new mineralized zone \(Pepas West\)

- Positive factor: High-grade surface samples \(up to 79.6 g/t Au\) indicating significant potential for strike extension

- Positive factor: Strong gold intercepts \(e.g., 2.65m at 3.14 g/t Au, 2.05m at 3.46 g/t Au\)

- Positive factor: Comprehensive QA/QC disclosure including certified labs and QP sign-off

- Positive factor: Project advancing towards feasibility

- Negative factor: Mixed drill results with several holes reporting no significant intersections

- Negative factor: True width of intercepts is unknown, potentially overstating apparent thickness

- Negative factor: Pepas West zone is narrower than the main Pepas deposit and its relationship is yet to be determined

Facts used in scoring: 17

## 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: The release includes detailed QA/QC protocols, including the use of blanks, standards, duplicates, and certified laboratories \(ALS Chemex, Actlabs\), and is signed off by a Qualified Person.

Evidence · text

> Industry standard QAQC protocols are put in place with approximately 10% of total submitted samples being blanks, repeats or Certified Reference Materials \(CRMs\). Samples for holes PEP-001 to PEP-011 were sent to the Medellin preparation facility of ALS Colombia Ltd, and then to the ISO 9001 certified ALS Chemex laboratory in Lima, Peru. Samples from PEP-012 onwards are sent to Medellin laboratory of Actlabs for preparation and fire assay, with some sample then sent to the Canadian Actlabs facility for multi element assay.

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that intersections are quoted as downhole thicknesses and true thicknesses are unknown.

Evidence · text

> Intersections are quoted as downhole thicknesses. True thicknesses are unknown.

**Cut-off Undisclosed**

Polarity: negative

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

Why it applies: The document states a lower cut-off of 0.3g/t Au over 3m for reporting gold intersections, but does not specify internal dilution rules.

Evidence · text

> Gold intersections are reported using a lower cut-off of 0.3g/t Au over 3m.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling program included holes around and beyond the northern extent of Pepas West to understand its breadth and strike extent, and high-grade surface samples suggest potential for substantial increase in strike length.

Evidence · text

> The additional five holes \(PEP095 to PEP099\) were drilled around and beyond the northern extent of Pepas West in order to better understand controls upon this mineralisation and its possible breadth and strike extent.

**Nearology Play**

Polarity: neutral

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

Why it applies: The value premise for Pepas West is based on its geological similarity and proximity \(100m west\) to the main Pepas zone, and high-grade surface samples along strike from Pepas West.

Evidence · text

> a new zone of mineralisation, geologically similar to Pepas, has been discovered approximately 100m west of the main Pepas zone.

## 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.
