# Nevgold Files NI 43-101 Technical Report For Mineral Resource Estimate on the Limousine Butte Gold-Antimony Project, Nevada Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/nevgold-files-ni-43-101-technical-report-for-mineral-resource-estimate-on-the-li--ea0ecd6b-2075-4696-9391-5c06042e3b8a Original source: https://www.globenewswire.com/news-release/2026/08/31/3353311/0/en/nevgold-files-ni-43-101-technical-report-for-mineral-resource-estimate-on-the-limousine-butte-gold-antimony-project-nevada.html Publisher: globenewswire Original announcement: 2026-08-31T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: NevGold Corp. - Ticker: NAU - Exchange: Unavailable - Region: Nevada - Primary commodity: Gold - Secondary commodities: Antimony, Silver - Document categories: Resource update - Extracted: 2026-08-31 14:39:55 UTC Narrative sentiment: 0.30 · Bullish ## Minestarters Atlas summary NevGold Corp. has filed the NI 43-101 technical report for its maiden Mineral Resource Estimate on the Limousine Butte gold-antimony project in Nevada. The report formalizes the previously announced estimate, outlining a large-scale oxide gold-antimony resource. The company highlights the strategic importance of the project and its potential for near-term antimony production from historical leach pads, with further drilling planned to expand and upgrade the resource. Reasoning: NevGold has filed the NI 43-101 technical report for its maiden Mineral Resource Estimate on the Limousine Butte gold-antimony project, confirming a significant gold-antimony resource in Nevada. While the MRE details were previously announced, this formal filing is a positive step, establishing a baseline for the project. However, the resource has a low Measured and Indicated component and marginal grades for an open-pit scenario. - Positive factor: Maiden Resource - Positive factor: NI 43-101 Compliant - Positive factor: QP/CP Signed - Positive factor: Open Pit Mining Method - Positive factor: Contained Gold Scale - Negative factor: Low M&I Percentage - Negative factor: Grades are Marginal - Negative factor: MRE Previously Disclosed Facts used in scoring: 79 ## Classification and evidence **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The technical report is explicitly stated to be prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects \('NI 43-101'\). Evidence · text > prepared by Gregory Z. Mosher, P. Geo., M.Sc. Applied, and Daniel W. Kappes, P.E. in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects \(“ NI 43-101 ”\) **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 report was prepared by Gregory Z. Mosher, P. Geo., M.Sc. Applied, and Daniel W. Kappes, P.E., and technical information was reviewed and approved by Greg French, CPG, NevGold’s Qualified Person. Evidence · text > prepared by Gregory Z. Mosher, P. Geo., M.Sc. Applied, and Daniel W. Kappes, P.E. **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The company explicitly refers to this as its 'maiden Mineral Resource Estimate'. Evidence · text > maiden Mineral Resource Estimate \(“ MRE ”\) for the Limousine Butte gold-antimony project **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: A significant portion of the resource \(117.5 Mt out of 132.7 Mt total\) is classified as Inferred. Evidence · table > 117.5 Context: Total Inferred **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 document clearly states the cut-off grades used for the resource estimate, including 0.30 g/t AuEq for most zones and 0.15 g/t Au for Northern Zones. Evidence · text > Mineral Resources for Leach Pads, Pre-Strip Dump, Resurrection, and Cadillac Valley are reported at a cut-off grade of 0.30 g/t AuEq. **Open Pit Mining Method** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The resource estimate is based on an 'open-pit mining scenario'. Evidence · text > open-pit mining scenario contemplating recovery of gold and antimony. **Stale Data Re-release** Polarity: negative Story-specific tag Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The document states 'There are no material differences between the MRE in the Technical Report and the information previously disclosed in the Company’s news release dated July 15, 2026,' indicating the MRE itself is not new information. Evidence · text > There are no material differences between the MRE in the Technical Report and the information previously disclosed in the Company’s news release dated July 15, 2026. ## Extracted facts Stored fact records: 79.

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.
