NevGold Expands Recent Mineral Resource Estimate With First 2026 Drillholes; 1.16% Antimony Over 3.0 Meters Within 1.38 g/t AuEq Over 50.3 Meters (0.31% Antimony and 0.19 g/t Au) From Surface

Summary

NevGold Corp. announced assay results from the first three drillholes of its 2026 program at the Limousine Butte Project in Nevada. These results significantly expanded the maiden oxide antimony-gold Mineral Resource Estimate (MRE) by over 100 meters outside the current block model, with all holes intercepting significant antimony-gold mineralization at grades consistently higher than the MRE. Key intercepts include 1.38 g/t AuEq over 50.3 meters from surface in LB26-003 Upper, and 3.30 g/t AuEq over 3.0 meters within 45.7 meters in LB26-001 Lower.

Reasoning: NevGold's initial 2026 drill results from the Limousine Butte Project demonstrate significant expansion of the maiden oxide antimony-gold MRE, with all three holes intercepting mineralization over 100 meters outside the current block model and showing grades consistently higher than the MRE, including notable near-surface high-grade AuEq intercepts.

Positive factors

  • MRE significantly expanded by over 100 meters outside current block model
  • Grades consistently higher than the existing MRE for both gold and antimony
  • Significant antimony-gold mineralization intercepted in all first three drillholes
  • High-grade intercepts from surface (e.g., 1.38 g/t AuEq over 50.3 meters from surface)
  • Strong QA/QC protocols disclosed, including ISO 17025 certified lab and QP sign-off

Negative factors

  • True width is an estimate (70-90% of downhole thickness) rather than a precise measurement

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

Facts used in scoring: 48

Classification and evidence

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: The release states that NevGold QA/QC protocols include insertion of duplicate, blank and standard samples, assays were completed by ISO 17025 certified American Assay Labs, and technical information was reviewed and approved by Greg French, CPG, a Qualified Person under NI 43-101.

Evidence · text

“NevGold QA/QC protocols are followed on the Project and include insertion of duplicate, blank and standard samples in all drill holes. A 30g gold fire assay and multi-elemental analysis ICP-OES method was completed by ISO 17025 certified American Assay Labs, Reno. Technical information contained in this news release has been reviewed and approved by Greg French, CPG, the Company’s Vice President, Exploration, who is NevGold’s Qualified Person (“QP”) under National Instrument 43-101 and responsible for technical matters of this release.”

Step-Out Extensionpositive

Mineralization extended beyond the previously known limit.

Why it applies: The company states that the results have significantly expanded the maiden oxide antimony-gold Mineral Resource Estimate with mineralization intercepted over 100 meters outside of the MRE block model.

Evidence · text

“These results have significantly expanded the maiden oxide antimony-gold Mineral Resource Estimate (“MRE”) with antimony-gold mineralization intercepted over 100 meters outside of the MRE block model”

Apparent Width Onlynegative

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 downhole thickness is reported and true width varies, being approximately 70% to 90% of downhole thickness, rather than providing a specific true width for each intercept.

Evidence · text

“*Downhole thickness reported; true width varies depending on drill hole dip and is approximately 70% to 90% of downhole thickness.”

Compositing Transparentpositive

Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The metal equivalent grade assumptions are clearly disclosed, including assumed metal prices and recoveries for gold and antimony.

Evidence · text

“**The gold equivalents (“AuEq”) are based on assumed metals prices of US$3,000/oz of gold and US$40,000 per tonne of antimony, and assumed metals recoveries of 80% for gold and 75% for antimony.”

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.
