## Minestarters Atlas summary

GoldMining Inc. announced initial assay results from its 2026 diamond core drilling program at the Yarumalito Project in Colombia, intersecting 399.9 metres of continuous gold-copper mineralization from surface in hole YAR-45. This significant intercept, grading 0.45 g/t gold equivalent, confirms the scale and continuity of the porphyry system and validates the updated 3D geological model. Assays for three additional holes are pending, with results expected to be integrated into an updated geological and mineral resource model.

Reasoning: Initial drill results from hole YAR-45 at the Yarumalito Project confirm wide, continuous gold-copper porphyry-style mineralization starting from surface, validating the geological model and indicating significant exploration upside. While true width is an estimate and assays for other holes are pending, the overall result is highly positive for the project.

- Positive factor: Exceptional width of continuous mineralization from surface

- Positive factor: Confirmation and validation of the geological model

- Positive factor: Good gold equivalent grade for a porphyry system

- Positive factor: Detailed QA/QC procedures disclosed

- Positive factor: Qualified Person sign-off

- Negative factor: True width is an estimate \(50% of downhole interval\)

- Negative factor: Assays for the majority of the drill program \(3 out of 4 holes\) are pending

- Negative factor: Metal equivalent calculation assumes 100% metallurgical recovery without test work

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 15

## Classification and evidence

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states that 'True width is estimated to be approximately 50% of downhole interval length'.

Evidence · text

> True width is estimated to be approximately 50% of downhole interval length based on current geological interpretation of sub-vertical P-1 intrusive phase contact orientations.

**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 a detailed 'Data Verification' section outlining sample preparation, laboratory certifications, and QA/QC procedures including pulp duplicates, standards, blanks, coarse duplicates, and field duplicates.

Evidence · text

> GoldMining has implemented a quality assurance and quality control program for the sampling and analysis of drill core samples, including pulp duplicates, mineralized standards and blank samples for every 20 samples; coarse duplicates for every 100 samples and field duplicates for every 50 samples.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The cut-off grades and maximum internal dilution rules for both the main composite interval and additional intercepts are clearly stated.

Evidence · text

> Cut-off grade applied for the entire drill hole composite interval \(from surface to 399.9 m EOH\) is 0.10 g/t AuEq with a maximum internal dilution of 5.0 consecutive metres. The additional composite intercepts are reported above a cut-off grade of 0.30 g/t AuEq with a maximum internal dilution of 3.0 consecutive metres.

**Nearology Play**

Polarity: neutral

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

Why it applies: The document highlights the project's location in proximity to known operations like Aris Mining's Marmato Mine and Collective Mining's Guayabales project.

Evidence · text

> The Project is located approximately 10 km north of Aris Mining's Marmato Mine and Collective Mining's Guayabales project.

**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: "\# GoldMining Intersects 400 Metres of Continuous Gold-Copper Mineralization at the Yarumalito Project, Colombia \*2026-1"

Reasoning: This sub-interval shows a low silver grade over a good width, contributing to the overall mineralization profile.

- Positive factor: Good intercept width \(36.0m\)

- Positive factor: True width estimated and disclosed \(18.0m\)

- Positive factor: Detailed QA/QC procedures disclosed

- Positive factor: Qualified Person sign-off

- Negative factor: Low silver grade for a porphyry system \(1.07 g/t Ag\)

- Negative factor: Metal equivalent calculation assumes 100% metallurgical recovery

- Negative factor: Assays for other holes are pending

#### Tags used in scoring

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: true\_width\_m is 18

**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

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: cutoff\_grade and internal dilution are both stated

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: drill\_program\_type is "mixed"

**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: "\# GoldMining Intersects 400 Metres of Continuous Gold-Copper Mineralization at the Yarumalito Project, Colombia \*2026-1"

## 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.
