## Minestarters Atlas summary

i-80 Gold Corp. announced high-grade gold assay results from its recent drilling campaign at the Archimedes Underground Project in Nevada. The results, including 24.6 g/t Au over 23.6 m, confirm and extend mineralization in the Upper Archimedes zone. Development of the project is advancing on schedule, with first gold production targeted for Q3 2026.

Reasoning: The drilling campaign returned multiple high-grade gold intercepts, including an exceptional 24.6 g/t Au over 23.6 m, confirming and extending mineralization at the Upper Archimedes zone, with development advancing on schedule and strong QA/QC disclosure.

- Positive factor: Exceptional gold grades

- Positive factor: Significant intercept lengths

- Positive factor: Confirmation of mineralization continuity

- Positive factor: Potential for resource extension

- Positive factor: Development advancing on schedule

- Positive factor: QP/CP signed

- Positive factor: QA/QC disclosed

- Negative factor: True width is an estimate

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

Facts used in scoring: 38

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 24.6 g/t Au over 23.6 m in hole iAU26-05 is exceptionally high-grade for an underground gold project, significantly exceeding the 15 g/t exceptional threshold and 300 g/t·m GT product threshold.

Evidence · table

> 24.6

Context: 23.6

**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 document states that 'True widths are estimated between approximately 40%-65% of core width', indicating that only apparent downhole widths are reported for the intercepts.

Evidence · text

> True widths are estimated between approximately 40%-65% of core width.

**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 explicitly mentions that 'i-80 Gold's QA/QC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream' and that MSALABS is an 'ISO9001 accredited laboratory'.

Evidence · text

> i-80 Gold's QA/QC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results.

**Infill Drilling**

Polarity: neutral

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

Why it applies: The document states that 'Infill drilling commenced in the fourth quarter of 2025 with a focus on further delineating Upper Archimedes' and the 'overall drill program is primarily focused on infill drilling'.

Evidence · text

> Infill drilling commenced in the fourth quarter of 2025 with a focus on further delineating Upper Archimedes

**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 technical information has been reviewed and approved by Paul Chawrun P.Eng. and Tyler Hill CPG., both qualified persons within the meaning of NI 43-101 and S-K 1300.

Evidence · text

> The technical information contained in this press release has been prepared under the supervision of, and has been reviewed and approved by Paul Chawrun P.Eng., Chief Operating Officer, and Tyler Hill CPG., Vice President, Geology, for the Company, each of whom are qualified persons within the meaning of National Instrument 43-101 - Standards of Disclosure for Mineral Projects \("NI 43-101"\) and S-K 1300.

## 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.
