## Minestarters Atlas summary

Nevgold Corp. has filed an NI 43-101 compliant technical report for its maiden Mineral Resource Estimate on the Limousine Butte gold-antimony project in Nevada, with an effective date of July 15, 2026. The MRE outlines a large-scale resource, including significant gold and antimony, and is signed off by Qualified Persons. The company highlights the potential for near-term antimony production from historical leach pads and notes that recent drilling has already expanded mineralization beyond this initial estimate.

Reasoning: Nevgold Corp. has filed its maiden NI 43-101 compliant MRE for the Limousine Butte project, establishing a significant gold-antimony resource, though a large portion is in the inferred category and the estimate may not reflect the most recent drilling.

- Positive factor: Maiden Mineral Resource Estimate establishes a baseline for the project

- Positive factor: NI 43-101 compliant and signed off by Qualified Persons

- Positive factor: Significant gold and antimony resources identified

- Positive factor: Potential for near-term antimony production from historical leach pads

- Positive factor: Metal equivalent assumptions for the main cut-off are disclosed

- Negative factor: A large portion of the resource is in the Inferred category, which is speculative

- Negative factor: The MRE effective date is July 15, 2026, but recent drilling has already expanded mineralization, suggesting the estimate is not fully current

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

Kappes, P.E. in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects \(“ NI 43-101 ”\) and supports the MRE disclosure made by the Company in its news release dated July 15, 2026. A full copy of the Technical Report can be found at SEDAR+ \( www.sedarplus.ca \) under the Company’s issuer profile. 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. NevGold CEO, Brandon Bonifacio, comments: “Our maiden, large-scale, oxide gold-antimony Mineral Resource Estimate was an important first step in delivering on our uniquely positioned opportunity at Limo Butte. We have delivered on one of the largest, most strategic, gold-antimony resources in the United States , and our recently announced first drill results from 2026 have already expanded mineralization from the initial MRE. We have the potential to advance Limo Butte to a near-term antimony production scenario from the already mined material on surface from the historical gold leach pads, while we systematically advance the other deposits with further drilling to add scale and increase grade . We have also made strong progress advancing the next phase of Engineering Studies, which is another key upcoming milestone for the Project. We will continue to build off this initial MRE, as it will be a very active next period as our drill program continues with over 35 holes with assays pending .” Limousine Butte Maiden Mineral Resource Estimate The tables below are extracted from the MRE disclosed in the Technical Report.

All mineral resources have been estimated in accordance with Canadian Institute of Mining, Metallurgy and Petroleum definitions, as required under NI 43-101 . The Mineral Resource Statement was prepared by Greg Mosher, P. Geo \(Global Mineral Resource Services, “ GMRS ”\) in accordance with NI 43-101. Ounce \(troy\) = metric tonnes x grade / 31.10348. All numbers have been rounded to reflect the relative accuracy of the estimate. The quantity and grade of reported Inferred Mineral Resources are uncertain in nature and there has not been sufficient work to define these Inferred Mineral Resources as Indicated or Measured Mineral Resources. It is reasonably expected that many of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration, however, there is no assurance that further exploration will result in all or any part of the Inferred Mineral Resources being converted into Indicated Mineral Resources. Tonnages and ounces in the tables are rounded to the nearest thousand and hundred, respectively. Numbers may not total due to rounding. There are no known legal, political, environmental, or other risks that could materially affect the development of the mineral resources. 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. for an open-pit mining scenario contemplating recovery of gold and antimony. Cut-off grades are based on a price of US$3,000/oz gold and US$35,000/tonne antimony, and a number of operating cost and recovery assumptions, including a reasonable contingency factor. Metallurgical recoveries of 80% for gold, and 75% for antimony were used. Densities based on lithology were assigned. Mineral Resources for Northern Zones are reported at a cut-off grade of 0.15 g/t Au for an open-pit mining scenario contemplating recovery of gold as there is currently no antimony data for the Northern Zones. Cut-off grade was based on a price of US$3,000/oz gold, and a number of operating cost and recovery assumptions, including a reasonable contingency factor. Metallurgical recoveries of 80% for gold was used. Densities based on lithology were assigned. Antimony mineral resources are reported as a subset of the total mineral resource within the conceptual pit shells used to constrain the total mineral resource in order to demonstrate potential for economic viability, as required under NI 43-101; mineralization outside of these pit shells is not reported as a mineral resource. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of the estimated mineral resources will be converted into mineral reserves. These Mineral Resource estimates include inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. All figures are rounded to reflect the relative accuracy of the estimate. Notes to Table 2: Open pit antimony subdomain is reported at a cutoff grade 0.1% antimony within the overall 0.30 g/t AuEq. cutoff. These higher-grade antimony zones are reported separately in Table 2 to illustrate the potential for antimony production from the Project and are contained within the overall mineral resource estimate reported in Table 1. Antimony zones are reported only if they lie within the global resource estimate in Table 1.

#### Tags used in scoring

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: category is "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: cutoff\_grade is stated

**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: qp\_signed is true

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: reporting\_standards includes ni\_43\_101

## 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.
