## Minestarters Atlas summary

i-80 Gold reported high-grade gold assay results from its infill drilling campaign at the Upper Archimedes Underground Project in Nevada. Key intercepts include 24.6 g/t Au over 23.6 meters and 10.2 g/t Au over 36.4 meters, confirming mineralization continuity and potential for extension. These results will support stope design and a new mineral resource estimate, with project development advancing on schedule for first gold production in Q3 2026.

Reasoning: The drilling campaign returned multiple high-grade gold intercepts, including a bonanza intercept of 24.6 g/t Au over 23.6 m, confirming continuity and extending mineralization at the Upper Archimedes zone, which supports future resource updates and mine planning.

- Positive factor: Exceptional high-grade gold intercepts

- Positive factor: Significant widths reported

- Positive factor: Confirms continuity of mineralization

- Positive factor: Potential for resource extension

- Positive factor: Strong QA/QC disclosure

- Positive factor: True width estimation provided

- Negative factor: True width is an estimate \(range\), not a precise figure

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 yields a grade-thickness product of 580.56 g/t·m, which significantly exceeds the 300 g/t·m exceptional threshold for underground gold.

Evidence · text

> 24.6 g/t Au over 23.6 m in hole iAU26-05 \(sulfide\)

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document explicitly states that true widths are estimated, providing a range of 40%-65% of core width.

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 includes a 'Technical Disclosure and Qualified Persons' section detailing QP sign-off, use of an ISO9001 accredited laboratory \(MSALABS\), and QA/QC procedures including CRM standards, duplicates, and blanks.

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. All samples were submitted to MSALABS \(MSA\) of Elko, NV, which is an ISO9001 accredited laboratory, independent of the Company. ... 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 repeatedly states that the drilling program is 'Infill drilling' with a focus on 'further delineating Upper Archimedes' and 'primarily focused on infill drilling to enhance confidence in the mine plan' and 'upgrade inferred resources'.

## 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.
