## Minestarters Atlas summary

Errington Metals has completed its 2025/2026 exploration program at the Balfour mineralized zone, part of the Sudbury Basin Project, with assay results from the 2025 drilling campaign showing multiple high-grade polymetallic intercepts. The program successfully confirmed continuity and extended mineralization, which remains open along strike and at depth, positioning the company for a planned maiden mineral resource estimate. The results include significant copper, zinc, lead, gold, and silver grades, with strong QA/QC protocols in place.

Reasoning: The drill results from the 2025 program at Balfour show multiple high-grade and wide polymetallic intercepts, with several exceeding exceptional thresholds for VMS deposits. The program successfully extended mineralization and is explicitly aimed at supporting a maiden resource estimate, indicating significant de-risking and growth potential. Strong QA/QC disclosure further supports the results.

- Positive factor: High-grade polymetallic intercepts, particularly in EMB-25-010 \(3.9m at 1.59% Cu, 16.32% Zn, 5.93% Pb, 0.47 g/t Au, 154.2 g/t Ag, 7.72% CuEq\) and EMB-25-022 \(6.8m at 1.25% Cu, 10.98% Zn, 7.92% Pb, 0.38 g/t Au, 227.2 g/t Ag, 6.98% CuEq\), which are exceptional for VMS deposits.

- Positive factor: Significant widths of mineralization, including 35.1m at 0.78% CuEq in EMB-25-017 and 33.2m at 1.36% CuEq in EMB-25-012, indicating potential for bulk tonnage.

- Positive factor: Step-out drilling confirmed extensions to mineralized shapes, and mineralization remains open along strike and down dip, indicating strong growth potential.

- Positive factor: The program is designed to support a planned maiden mineral resource estimate, de-risking the project.

- Positive factor: Comprehensive QA/QC procedures are disclosed, including certified labs and QP sign-off, enhancing data credibility.

- Positive factor: True width is estimated at 70-100% of downhole length, providing confidence in the reported thicknesses.

- Negative factor: Assay results for the 2026 drilling program are still pending, meaning the full scope of the recent exploration success is not yet known.

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

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept in EMB-25-010 of 3.9m at 7.72% CuEq \(including 1.59% Cu, 16.32% Zn, 5.93% Pb, 0.47 g/t Au, 154.2 g/t Ag\) is exceptionally high-grade for a VMS deposit.

Evidence · table

> 7.72

Context: 3.9

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept in EMB-25-022 of 6.8m at 6.98% CuEq \(including 1.25% Cu, 10.98% Zn, 7.92% Pb, 0.38 g/t Au, 227.2 g/t Ag\) is exceptionally high-grade for a VMS deposit.

Evidence · table

> 6.98

Context: 6.8

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document states that true width represents 70-100% of downhole depths as drill holes are designed perpendicular to the regional stratigraphic orientation.

Evidence · table

> True width represents 70-100% true width as drill holes are designed perpendicular to the regional stratigraphic orientation.

**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 detailed QA/QC procedures, mentioning Certified Reference Material standards, blanks, field duplicates, and accredited laboratories \(ALS Canada, MSALABS\).

Evidence · text

> Assay lab results have been verified by Errington Metals via Certified Reference Material standards, blanks and field duplicates. Samples were submitted to either ALS Canada in Sudbury Ontario or MSALABS in Timmins, Ontario who both meet the guidelines of ISO17025 accreditation and ISO9001, ISO14001 and ISO45001 certification.

**QP/CP Signed**

Polarity: positive

Story-specific tag

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: The scientific and technical information has been reviewed and approved by Frank Santaguida, PhD., P.Geo., a qualified person under NI 43-101.

Evidence · text

> The scientific and technical information in this press release has been reviewed and approved by Frank Santaguida, PhD., P.Geo. Mr. Santaguida is Vice President, Exploration for Errington Metals Corp. and is a qualified person under National Instrument 43-101.

**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: The CuEq calculation is provided for illustrative purposes only, with no allowance for payability, smelter terms, refining charges, penalties, or deleterious elements.

Evidence · table

> Copper equivalent values are provided for illustrative purposes only. No allowance has been made for payability, smelter terms, refining charges, penalties, or deleterious elements.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Step out drilling confirmed extensions to mineralized shapes and the mineralized shapes remain open both down dip and along strike.

## 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.
