## Minestarters Atlas summary

Americas Gold and Silver Corporation announced high-grade drill results from its Galena Complex, including new vein discoveries at the Galena and Crescent Mines. The drilling, part of the company's largest-ever exploration and resource conversion program, returned exceptional silver, copper, lead, and antimony intercepts, with some exceeding currently modeled grades. These results are expected to significantly enhance future mine plans and are supported by comprehensive QA/QC procedures.

Reasoning: Americas Gold and Silver reported exceptional high-grade silver, copper, lead, and antimony drill results from its Galena Complex, including new vein discoveries and significant extensions of known mineralization, which are expected to positively impact future mine plans. The results are supported by comprehensive QA/QC.

- Positive factor: High-grade intercepts across multiple commodities \(Ag, Cu, Pb, Sb\)

- Positive factor: Discovery of new high-grade veins at both Galena and Crescent Mines

- Positive factor: Significant extension of existing veins, expanding mineralized footprint

- Positive factor: Infill drilling regularly intersecting higher silver grades than currently modeled

- Positive factor: Robust QA/QC procedures including ISO-17025 accredited labs and QP sign-off

- Positive factor: True width disclosed for all tabular intercepts

- Negative factor: Some intercepts have very narrow true widths, which may impact mineability

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

Facts used in scoring: 125

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Multiple silver intercepts exceed the 500 g/t exceptional threshold, including 20,124 g/t Ag, 9,611 g/t Ag, and 7,123 g/t Ag.

Evidence · text

> 1,062 G/T AG, 0.7% CU OVER 1.3 METERS

**True Width Disclosed**

Polarity: positive

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

Why it applies: Both tables explicitly state 'True Width \(m\)' for all reported intercepts.

Evidence · table

> True Width \(m\)

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling program is described as 'exploration drilling' and mentions 'significantly extending existing major veins' and 'expanding the 2025 discovery to 200m along strike and 200m in vertical extent'.

Evidence · text

> significantly extending existing major veins on multiple levels of the mine. I'd like to congratulate the entire Galena team for their hard work and exceptional safety record as we continue to identify new targets to feed the mine's significant future. Our recent drilling across the Galena Complex has continued to deliver exceptional results. The new vein discovery on the operating 49 level \(49-817 intersecting 1.2m of 1,061 g/t Ag, 0.7% Cu and 0.6% Sb\) is not only high grade, but also very close to our minimum mining width for our ongoing transition to long hole stoping. The high-grade discovery of the 9 Vein \(24-407 intersecting 0.4m of 7,123 g/t Ag, 3.24 %Cu and 1.81% Sb\) in an area without any vein projections is a typical example of the numerous opportunities for new discoveries at Galena, even in higher levels with significant historical mining. Moving over to Coeur, the 520 Vein system continues to grow, with recent drilling expanding the 2025 discovery to 200m along strike and 200m in vertical extent while all directions remain open for further expansion.

**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 practices, including the use of certified reference materials, field duplicates, blanks, and independent ISO-17025 accredited laboratories \(AAS, SVL, ALS Global\), with sign-off by a Qualified Person.

Evidence · text

> The Company's standard QA/QC practices were utilized to ensure the integrity of the core and sample preparation at the Galena Complex through delivery of the samples to the assay lab. The drill core was stored in a secure facility, photographed, logged and sampled based on lithologic and mineralogical interpretations. Standards of certified reference materials, field duplicates and blanks were inserted as samples shipped with the core samples to the lab. Analytical work was carried out by American Analytical Services Inc. \("AAS"\) located in Osburn, Idaho, or SVL Analytical located in Kellogg Idaho. AAS and SVL are independent, ISO-17025 accredited laboratories. Sample preparation includes a 30-gram pulp sample analyzed by atomic absorption spectrometry \("AA"\) techniques to determine silver, copper, and lead, using aqua regia for pulp digestion. Samples returning values over 514 g/t Ag are re-assayed using fire-assay techniques for silver. Additionally, samples returning values over 23% Pb are re-assayed using titration techniques. Duplicate pulp samples are sent out quarterly to ALS Global, an independent, ISO-17025 accredited laboratory based in Reno, Nevada to perform an independent check analysis. A conventional AA technique was used for the analysis of silver, copper and lead at ALS Global with the same industry standard procedures as those used by AAS. The assay results listed in this report did not show any significant contamination during sample preparation or sample bias of analysis.

**Infill Drilling**

Polarity: neutral

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

Why it applies: The program is explicitly described as 'substantial infill and step-out exploration drilling' and aims to 'infill drill the existing Mineral Resource at Alhambra and South Veins'.

Evidence · text

> The assays reported today are a result of substantial infill and step-out exploration drilling conducted across multiple target areas at the Galena, Coeur \(see Figure 1\), and Crescent \(see Figure 2\) mines.

**Deleterious Elements Present**

Polarity: negative

Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release.

Why it applies: Antimony \(Sb\) and Lead \(Pb\) are reported in significant percentages in many intercepts, which can be penalty elements.

Evidence · text

> high-grade Ag-Cu-Pb-Sb drill results

**New Vein Discovery**

Polarity: positive

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The release highlights 'new vein discoveries at Galena and Crescent' and 'discovery of two new veins in the vicinity of Alhambra'.

Evidence · text

> Drilling has delivered new vein discoveries at Galena and Crescent as well returned infill drill intercepts that are regularly intersecting higher silver grades than the currently modeled Mineral Resource.

## 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.
