## Minestarters Atlas summary

Unico Silver reported Phase 3 drilling results from Cerro Leon, highlighting the highest silver intercept to date at Marta Norte and multiple strong silver-equivalent intercepts across the project. The program combined infill and extension drilling, and the company says the results support a Q3 2025 MRE update. The release also includes collar locations, QA/QC details, and the AgEq calculation assumptions.

Reasoning: The release is primarily a drilling-results announcement with numerous significant silver-equivalent intercepts and explicit resource-oriented context. It is materially positive because it includes standout intercepts and supports the planned MRE update, though the reported widths are downhole and some contextual risk remains around equivalent-grade assumptions.

- Positive factor: Reported the highest silver intercept to date at Cerro Leon

- Positive factor: Multiple strong AgEq intercepts from both oxide and sulphide zones

- Positive factor: Program supports a Q3 2025 MRE update and confirms infill/extension drilling success

- Positive factor: QA/QC, assay laboratory, compositing cut-off and internal dilution were disclosed

- Negative factor: Several key intercepts are reported as apparent downhole widths rather than true widths

- Negative factor: AgEq depends on disclosed metal-equivalent assumptions and historical metallurgical work

- Negative factor: Some holes were still pending at the time of the appendix

- Rubric flag: drill\_results vs resource\_update dominance — Primary category is drill\_results because the current event is Phase 3 drilling with many new intercepts, while the resource table is supporting background.

Facts used in scoring: 214

## Classification and evidence

**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 states blanks, duplicates and standards, and names Alex Stewart Laboratories.

Evidence · text

> Blanks: 1 in 50 • Duplicates: 1 in 20 • Standards: 1 in 25

**Compositing Transparent**

Polarity: positive

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

Why it applies: The report states the drill intercepts are calculated using greater than 40gpt AgEq with no more than 3m of internal dilution.

Evidence · text

> Mineralised drill hole intercepts are calculated using greater than 40gpt AgEq with no more than 3m of internal dilution.

**True Width Disclosed**

Polarity: positive

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

Why it applies: The JORC table says qualification of true widths are provided in the drill hole discussion, although individual table intercepts are still downhole widths.

Evidence · text

> Qualification of true widths are provided in the drill hole discussion.

**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 main intercepts are reported as downhole intervals and the table defines AgEq GT as grade multiplied by downhole mineralised interval.

Evidence · text

> AgEq GT = Silver equivalent grade multiplied by downhole mineralised interval \(Grade Thickness\)

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The resource section repeats the Cerro Leon MRE from a prior ASX release dated 18 May 2023 and says no material assumptions or technical parameters have changed.

Evidence · text

> extracted from the ASX release by Unico Silver entitled “Cerro Leon Resource Grows 84% to 92Moz” dated 18 May 2023

**Infill Drilling**

Polarity: neutral

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

Why it applies: The summary says Phase 3 drilling comprised infill drilling within shallow oxide mineralisation to improve confidence for the Q3 MRE.

Evidence · text

> Phase 3 drilling comprised infill drilling within shallow oxide mineralisation to improve confidence for the Q3 MRE

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The release says the program included extension drilling to expand the limits of both oxide and sulphide mineralisation at depth and along strike.

Evidence · text

> further extension drilling at all prospects to expand the limits of both oxide and sulphide mineralisation at depth and along strike.

**Nearology Play**

Polarity: neutral

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

Why it applies: The project is described as being strategically located within the same structural corridor as AngloGold Ashanti’s Cerro Vanguardia mine.

Evidence · text

> within the same structural corridor that is host to AngloGold Ashanti’s world-class Cerro Vanguardia mine

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.

Why it applies: AgEq is disclosed, but the equivalent calculations rely on stated prices and recoveries rather than a full current economic model; users must still interpret the equivalent cautiously.

Evidence · text

> AgEq = Ag \(g/t\) + 79.18 x Au \(g/t\) + 25.56 x Pb \(%\) + 39.41 x Zn \(%\)

## 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.
