## Minestarters Atlas summary

i-80 Gold announced additional high-grade gold assay results from its 2025-2026 infill drill campaign at the Archimedes Underground Project in Nevada, including 16.2 g/t Au over 56.4 meters. These results confirm continuity and extend known mineralization, with potential upside from oxide material not yet in the resource estimate. The company also provided an update on its existing mineral resource estimate for Archimedes, which includes 1.8 million tonnes Indicated at 7.6 g/t Au and 4.2 million tonnes Inferred at 7.3 g/t Au, and updated the timing of technical studies for other projects.

Reasoning: The announcement reports multiple high-grade gold intercepts with significant widths from infill drilling at the Archimedes Underground Project, extending known mineralization and confirming continuity. The resource update, while a restatement, shows strong grades for both indicated and inferred categories, with moderate overall confidence. Robust QA/QC procedures and QP sign-off enhance credibility, though true widths are only estimated as a range for drill results and the resource is a historical restatement.

## 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 that i-80 Gold's QA/QC program includes regular insertion of standards, duplicates, and blanks, and that MSALABS is an ISO9001 and ISO/IEC 17025 accredited laboratory.

Evidence · text

> i-80 Gold's QA/QC program includes regular insertion of standards, duplicates, and blanks into the sample stream with a stringent review of all results. For a description of the data verification, assay procedures and the quality assurance program and quality control measures applied by the Company, please see the Company's Annual Report on Form 10-K for the year ended December 31, 2025, as well as the information in respect of data verification, key assumptions, parameters, risks and other factors contained in the PEA and the corresponding Initial Assessment dated March 31, 2025, each as filed under the Company's profile on SEDAR+ at www.sedarplus.ca and under the Company's profile on EDGAR at www.sec.gov .

**QP/CP Signed**

Polarity: positive

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., who are 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., Executive Vice President and Chief Operating Officer, and Tyler Hill CPG., Vice President Geology, for the Company, each of whom are qualified persons within the meaning of NI 43-101 and S-K 1300.

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The resource estimate and technical studies are prepared in accordance with National Instrument 43-101.

Evidence · text

> prepared in accordance with National Instrument 43-101- Standards of Disclosure for Mineral Projects \("NI 43-101"\)

**Infill Drilling**

Polarity: neutral

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

Why it applies: The drill campaign is described as an 'infill drill campaign' focused on 'further delineating the upper 426 zone to approximately 60-foot spacing in preparation for the start of mining'.

Evidence · text

> infill drill campaign within the upper 426 zone of the Archimedes Underground Project

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drill results are noted to 'extend the known mineralized area' and demonstrate 'an expansion of the mineralization beyond the boundaries defined by the current mineral resource estimate'.

Evidence · text

> demonstrating significant widths and continuity of high-grade material that extends the known mineralized area

**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: True widths are provided as an estimated range \(40%-65% of core width\) rather than specific values for each intercept.

Evidence · text

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

**Historical Estimate Only**

Polarity: negative

Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.

Why it applies: The mineral resource estimate is a restatement of a prior estimate with an effective date of December 31, 2025, and was reviewed to confirm it remains current.

Evidence · text

> As of December 31, 2025, Archimedes hosts an Indicated Mineral Resource of 1.8 million tonnes containing 436,000 ounces of gold grading 7.6 grams per tonne and an Inferred Mineral Resource of 4.2 million tonnes containing 988,000 ounces of gold grading 7.3 grams per tonne \(1\) .

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The resource estimate explicitly states the pressure oxidation cutoff grades for the 426 and Ruby Deeps deposits.

Evidence · text

> Pressure oxidation cutoff grades are 5.06 and 5.48 Au g/t \(0.148 and 0.160 opt\) for the 426 and Ruby Deeps deposits respectively.

## 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.
