## Minestarters Atlas summary

Mackay Gold & Silver reports initial drill results from its inaugural program at Occidental South, Nevada, with significant step-out intercepts extending gold mineralization. Highlights include 59.4 meters at 1.00 g/t gold, 47.2 meters at 1.15 g/t gold \(including 4.57 meters at 7.57 g/t gold\), and 48.8 meters at 0.97 g/t gold. These results nearly double the strike length of gold mineralization to 550 meters and confirm the potential for shallow oxide gold expansion.

Reasoning: The initial drill results from Mackay Gold & Silver's inaugural program at Occidental South are highly positive, demonstrating significant step-out extensions of gold mineralization with good widths and grades, validating the project's potential. The high novelty and successful expansion of the mineralized footprint are key drivers of positive sentiment, despite the lack of precise true width reporting and low silver grades.

- Positive factor: Significant step-out drilling successfully extended mineralization along strike by 150-250 meters, nearly doubling the known strike length at Occidental South.

- Positive factor: Multiple thick intercepts of moderate to strong gold grades, including a high-grade sub-interval of 7.57 g/t Au over 4.57 m, confirm continuity and expansion potential.

- Positive factor: The results are from the inaugural drill program, representing new discoveries and validating the prospectivity of the Occidental-Brunswick Lode.

- Positive factor: QA/QC procedures are disclosed, including certified lab, QP sign-off, and methods like blanks, standards, and duplicates, enhancing data credibility.

- Positive factor: The project targets shallow oxide gold mineralization, which is typically amenable to lower-cost open-pit mining methods.

- Negative factor: True width is estimated rather than precisely stated for each intercept, which may overstate actual thickness.

- Negative factor: Silver grades are generally low and below typical economic thresholds for epithermal deposits, indicating it is a minor byproduct.

- Negative factor: Assays are pending for the majority of the planned drill program, meaning the full picture of the program's success is not yet available.

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

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drill program involved 150 to 250-meter step-outs along strike, extending mineralization a further 250m north of previous historic drilling and nearly doubling the strike length of gold mineralization.

**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 details QA/QC procedures including the collection and analysis of duplicate samples, and the insertion of blanks and standards, with assay work performed by ALS Geochemistry, which is ISO/IEC 17025:2017 and ISO 9001:2015 certified.

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: The scientific and technical information in the news release has been reviewed and approved by Darwin Green, CEO and Director, who is a Qualified Person under NI 43-101.

**Compositing Transparent**

Polarity: positive

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

Why it applies: The release states that reported intersections are based on a 0.1 g/t cut-off with a maximum of 20 ft internal dilution below cut-off.

Evidence · table

> Reported intersections based on a 0.1 g/t cut-off with maximum of 20 ft internal dilution below cut-off

**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 release states that reported widths are drilled width and true width is only estimated at 70% to 95% of drilled width, without providing specific true width values for each intercept.

Evidence · table

> Reported widths are drilled width, true width estimated at 70% to 95% of drilled width

**Maiden Resource**

Polarity: neutral

Story-specific tag

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

Why it applies: The results are from the 'inaugural drill program' and are the 'first holes to be drilled by Mackay Gold & Silver', indicating a new exploration phase for the company at this project.

## 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.
