## Minestarters Atlas summary

Unico Silver reported an updated Mineral Resource Estimate for the Cerro Leon project in Santa Cruz, Argentina, including a maiden resource at Conserrat. The company says the combined resource increased to 91.3 million silver equivalent ounces, up 84% in silver equivalent ounces and 94% in tonnes versus the 2014 Pingüino estimate. The annual report also discusses a $5 million placement and a share purchase plan completed during the year.

Reasoning: The main substantive event is an updated Cerro Leon Mineral Resource Estimate, with a meaningful uplift from the prior Pingüino estimate and a maiden resource at Conserrat. It is positive for scale and project maturity, though the estimate still carries a substantial inferred component and includes historical foreign-estimate comparison.

- Positive factor: maiden resource at Conserrat

- Positive factor: combined Cerro Leon MRE increased to 91.3 Moz AgEq

- Positive factor: 94% increase in tonnes and 84% increase in silver equivalent ounces versus the 2014 Pingüino Estimate

- Positive factor: JORC 2012 compliance stated

- Positive factor: cut-off grades disclosed

- Negative factor: resource includes a large inferred component

- Negative factor: foreign estimate at Pingüino was published during 2014

- Negative factor: multiple values are reported as silver equivalent rather than standalone economics

Facts used in scoring: 16

## Classification and evidence

**JORC Compliant**

Polarity: positive

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

Why it applies: The report states, "The preceding statements of Mineral Resources conforms to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves \(JORC Code\) 2012 Edition."

Evidence · text

> The preceding statements of Mineral Resources conforms to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves \(JORC Code\) 2012 Edition.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The report says the Pingüino Estimate was "published during 2014 under Canadian Technical reporting National Instrument \(NI\) 43-101 standards."

Evidence · text

> published during 2014 under Canadian Technical reporting National Instrument \(NI\) 43-101 standards.

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The document states both the 50 g/t and 150 g/t silver equivalent cut-off grades used for reporting.

Evidence · text

> At all prospects, the MRE only considered material within 150 m of the surface at a 50 g/t silver equivalent cut-off grade

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable.

Why it applies: The release says the updated MRE includes "a maiden resource at Conserrat."

Evidence · text

> a maiden resource at Conserrat

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**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

**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.

Why it applies: reporting\_standards includes ni\_43\_101

**No Contained Metal**

Polarity: negative

Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained\_metal was not reported

**No QP/CP Disclosure**

Polarity: negative

Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.

Why it applies: no Qualified or Competent Person is named anywhere in the release

**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

**Stale Estimate**

Polarity: negative

Definition: Effective date is &gt;2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: effective date is 3.5 years before this release

## 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.
