## Minestarters Atlas summary

Mandalay Resources reported high-grade gold and antimony drill intercepts from its Costerfield operation in Victoria, Australia. The drilling focused on extending and infilling the Shepherd and Kendall vein systems, as well as exploring new zones below and north of the Cuffley deposit. Notable results include 751.7 g/t gold and 1.8% antimony over 0.22 m, and 550.0 g/t gold over 0.15 m, indicating potential for resource expansion and mine life extension.

Reasoning: The announcement details numerous high-grade gold and antimony intercepts across multiple vein systems, demonstrating successful resource expansion and exploration in both established and new areas, which is highly positive for mine life and future production.

- Positive factor: High-grade gold and antimony intercepts

- Positive factor: Extension of known mineralization

- Positive factor: Discovery of new mineralized zones

- Positive factor: Near-mine focus leveraging existing infrastructure

- Positive factor: Detailed QA/QC disclosure

- Negative factor: Many intercepts are narrow, typical for vein-style deposits

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

Facts used in scoring: 110

## Classification and evidence

**True Width Disclosed**

Polarity: positive

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

Why it applies: True widths are consistently reported in Table 1 for most intercepts, e.g., 'TRUE WIDTH \(M\) 0.43'.

Evidence · text

> TRUE WIDTH \(M\)

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The document explicitly mentions 'Extension and Infill drilling' and 'extending the potential of the westernmost vein sets'.

Evidence · text

> Extension and Infill drilling on Shepherd and Kendall veining provides confidence on extension

**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 QA/QC section mentioning certified labs, QP sign-off, and methods like standards and blanks.

Evidence · text

> Site geological and metallurgical personnel have implemented a QA/QC procedure that includes systematic submission of standard reference materials and blanks

**Infill Drilling**

Polarity: neutral

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

Why it applies: The drilling program is described as 'Extension and Infill drilling' for Shepherd and Kendall veins.

Evidence · text

> Extension and Infill drilling on Shepherd and Kendall veining

## 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.
