NevGold Corp (CVE: NAU) (OTCMKTS: NAUFF) (FRA: 5E50) has filed a technical report supporting its maiden Limousine Butte mineral resource estimate.
The Nevada-focused explorer filed the report on SEDAR+ following its initial resource announcement on July 15. The report covers the company’s Limousine Butte gold-antimony project in Nevada and carries an effective date of July 15. It is dated Aug. 24 but was released Aug 31.
Additionally, NevGold said the report contains no material differences from the mineral resource estimate announced in July.
Gregory Mosher and Daniel Kappes prepared the report under Canada’s National Instrument 43-101 standards for mineral project disclosure.
A mineral resource estimate calculates the amount and grade of potentially economic minerals based on geological evidence and sampling.
NevGold’s estimate outlines a large oxide gold-antimony resource, giving the company a baseline for further drilling and engineering work.
Meanwhile, the company has continued drilling beyond the areas included in the maiden resource.
NevGold recently reported that its first 2026 drilling results extended known mineralization outside the initial estimate.
Additionally, more than 35 completed drill holes currently have assay results pending.
CEO Brandon Bonifacio said the company intends to use continued drilling to expand the resource and identify higher-grade mineralization.
NevGold is also examining whether it can recover antimony from previously mined material sitting in historical gold leach pads.
Those pads contain rock extracted during earlier mining operations and placed on surface for processing.
Consequently, they could offer NevGold a potential route toward antimony production without first developing an entirely new mine.

Limousine Butte resource spans gold and higher-grade antimony
Chart via Nevgold.
At a 0.30 grams per tonne gold-equivalent cut-off, Limousine Butte contains 15.2 million tonnes of measured and indicated resources. The material grades 0.37 g/t gold and contains 181,400 ounces of gold and 31,800 tonnes of antimony.
Additionally, NevGold reported 117.5 million inferred tonnes grading 0.32 g/t gold, containing 1.2 million ounces of gold and 75,700 tonnes of antimony.
Resurrection contributes most of the measured and indicated resource. Meanwhile, Cadillac Valley contains 57.2 million inferred tonnes and 686,500 ounces of gold. The Northern Zones add another 31.7 million inferred tonnes containing 255,000 ounces.

NevGold also presented a smaller resource containing material with higher average antimony grades.
This estimate includes 11.3 million measured and indicated tonnes containing 29,600 tonnes of antimony at 0.26 per cent.
Additionally, 26.9 million inferred tonnes contain 48,100 tonnes of antimony grading 0.18 per cent. Resurrection accounts for 22,700 tonnes of measured and indicated antimony and another 27,600 inferred tonnes.
Cadillac Valley contributes another 20,000 tonnes of inferred antimony. Meanwhile, the historical leach pads contain 6,300 tonnes of measured and indicated antimony. The pads have already been mined and remain stored at surface, potentially simplifying initial development.

The estimate also shows how the resource changes when NevGold applies different gold-equivalent cut-off grades.
At 0.60 g/t, the project contains 8.9 million measured and indicated tonnes and 51.8 million inferred tonnes.
However, lowering the cut off to 0.30 g/t increases those figures to 15.2 million and 117.5 million tonnes, respectively. At 0.15 g/t, they rise further to 23.1 million and 221.9 million tonnes. Gold grades move in the opposite direction as NevGold includes more lower grade material.
Consequently, higher cut offs produce smaller resources with better average grades, while lower cut offs capture substantially more mineralized rock.
Engineering program one of NevGold’s major milestones
The company has described this material as one possible near term production opportunity at Limousine Butte.
Furthermore, NevGold is advancing engineering studies to assess the project’s development options.
The work will help determine how the company could process mineralized material and develop the project economically.
Bonifacio said the engineering program represents one of NevGold’s next major project milestones.
NevGold plans to continue drilling the other deposits at Limousine Butte while evaluating the historical leach pad material.
