## Minestarters Atlas summary

Austral Gold announced an updated NI 43-101 and JORC-compliant technical report for its Guanaco Mine in Chile, outlining a 14-year mine life and a post-tax NPV of US$192.1 million. The report details Proven and Probable Mineral Reserves of 18.1 Mt at 0.84 g/t Au and 5.43 g/t Ag, containing 352 Koz Au and 1.493 Moz Ag, alongside Measured & Indicated Resources of 17.0 Mt at 0.94 g/t Au and 6.11 g/t Ag. A significant portion of the reserves \(32% of tonnes\) is contingent on obtaining environmental permits for the Inesperada and Dumbo areas.

Reasoning: The updated technical report outlines a significantly improved project NPV and extended mine life for the Guanaco Mine, supported by updated resource and reserve estimates, although a material portion of the reserves is contingent on future permitting.

- Positive factor: Increased NPV to US$192.1 million

- Positive factor: Extended mine life to 14 years

- Positive factor: Updated Mineral Resource and Reserve estimates

- Positive factor: Leveraging existing infrastructure reduces execution risk and capital intensity

- Positive factor: Report is NI 43-101 and JORC compliant

- Positive factor: Qualified Persons sign-off

- Negative factor: Substantial portion of Mineral Reserves \(32% of tonnes, 53% of gold, 55% of silver\) is contingent on outstanding environmental permits for Inesperada and Dumbo areas, targeted for Q4 2026 / Q1 2027

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

Facts used in scoring: 38

## Classification and evidence

**Heap Leach Route**

Polarity: neutral

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: the document describes a heap\_leach route \("heap leach"\)

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the document describes a mill\_cil route \("agitated leach"\)

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route \("gravity"\)

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

#### Tags used in scoring

**Probable Reserve**

Polarity: positive

Definition: Indicated Resource with demonstrated economic viability after applying modifying factors.

Why it applies: category is "probable"

**Cut-off Undisclosed**

Polarity: negative

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

Why it applies: no cutoff\_grade was stated

**QP/CP Signed**

Polarity: positive

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: qp\_signed is true

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: reporting\_standards includes jorc

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: the release compares against a previous estimate

**PFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Pre-Feasibility Study — requires adequate M&I component.

Why it applies: the release names the study this estimate supports

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: the release names the study this estimate supports

## 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.
