NEVGOLD (NAUFF) Stock Price, News & Analysis

NevGold Corp (OTCQX: NAUFF; TSXV: NAU; Frankfurt: 5E50) is a mineral exploration and development company focused on gold and antimony projects in the Western United States. According to company news releases, NevGold is advancing the oxide gold–antimony Limousine Butte Project in Nevada (“Limo Butte”) and the open-pit, heap-leach Nutmeg Mountain gold project in Idaho, along with the Zeus copper project in Idaho.

NevGold operates in the mining, quarrying, and oil and gas extraction sector, with activities that align with dimension stone mining and quarrying classifications. Its projects are described in technical and exploration updates that emphasize oxide gold and antimony mineralization, metallurgical testwork, and the preparation of Mineral Resource Estimates (“MREs”).

Limousine Butte gold–antimony project in Nevada

The company’s disclosures describe Limousine Butte as an oxide gold–antimony project in Nevada, a well-known mining jurisdiction. Work at Limo Butte is centered on the Resurrection Ridge and Cadillac Valley target areas, where NevGold has integrated historical drilling, new mapping, and surface sampling to build an updated geological model. The company reports that the Devonian Pilot Shale is the principal local host to Carlin-type mineralization at Limousine Butte, with positive gold grades commonly associated with silicification and jasperoid breccias that also host elevated antimony.

NevGold’s news releases highlight the discovery and expansion of a near-surface, high-grade oxide antimony–gold zone known as the Bullet Zone at Resurrection Ridge. Step-out drilling in 2025 (for example, hole LB25-002 and LB25-009) intersected multiple horizons of gold and antimony mineralization beneath an older thrust dolomite unit, confirming a new geological model in which the dolomite was thrust over the prospective Pilot Shale. The company states that this model materially expands the potential mineralization footprint by preserving the Pilot Shale more than one kilometer east of prior drilling at Resurrection Ridge.

NevGold has also described historical small-scale antimony workings within the Limo Butte project boundary, including the Nevada Antimony Mine and the Lage Antimony Prospect, where stibnite was extracted from hydrothermal breccias via shallow pits. Historical rock-chip sampling in the past-producing Golden Butte pit, cited from a Brigham Young University thesis, returned numerous assays exceeding 1% antimony in jasperoid breccias, with some samples over 5% antimony and a reported sample grading 9.6% antimony with visible stibnite and stibiconite.

Antimony metallurgical testwork and leach pad potential

NevGold has completed multiple phases of metallurgical testwork on antimony-bearing material from Limousine Butte. According to company releases, composite samples from Resurrection Ridge, Cadillac Valley, and surface outcrops at the historically mined Golden Butte pit were tested by Kappes, Cassiday & Associates in Reno, Nevada. The testwork evaluated gravity, flotation, and leaching methods. The company reports that acid leaching achieved antimony extraction recoveries ranging from approximately 75% to 92% in initial work, and subsequent Phase II testing on a wider range of antimony grades (down to around 0.1% Sb) showed recoveries up to 85% in lower-grade material and up to 92% in higher-grade samples. NevGold states that antimony recovery has minimal to no impact on gold recovery in potential combined gold–antimony scenarios.

In addition to fresh rock mineralization, NevGold has identified large quantities of previously mined material on historical gold leach pads at Limo Butte. Company disclosures estimate, based on historical records, that between 2.4 million and 3.0 million tonnes of previously mined material are present in crushed and run-of-mine (“ROM”) leach pads at surface from mining operations in 1989–1990 that were focused on gold and did not target antimony. NevGold’s pit sampling of these pads returned consistent antimony and gold grades, and the company describes the leach pads as an opportunity for potential near-term antimony production, with additional potential to extract remaining gold after antimony processing.

District-scale geology and exploration strategy

Across the Limousine Butte land package, NevGold’s updated geological model outlines multiple gold–antimony target corridors that follow outcrops and projected subsurface positions of the Pilot Shale. The company notes that repeated faulting and thrusting provided fluid pathways and focused mineralization, creating structurally prepared horizons that host Au–Sb mineralization. The strike length between Resurrection Ridge and Cadillac Valley is described as more than 5 kilometers within an overall project-scale strike length of approximately 20 kilometers.

NevGold has also reported staking additional claims at Limousine Butte, adding several square kilometers of ground with outcropping antimony–gold mineralization. Rock-chip sampling on this newly staked ground has returned gold and antimony values cited in company news, and the geological setting is described as similar to other antimony–gold targets at the project.

Nutmeg Mountain open-pit, heap-leach gold project in Idaho

Beyond Nevada, NevGold is advancing the Nutmeg Mountain gold project in southwest Idaho. The company describes Nutmeg Mountain as a low-sulphidation epithermal gold deposit located near Weiser, Idaho, with a land package of approximately 1,724 hectares comprising federal unpatented claims, patented claims, and private leases. Historical and recent drilling total over 71,000 meters across core, reverse circulation, and rotary holes.

An updated open-pit, oxide, heap-leach Mineral Resource Estimate for Nutmeg Mountain has been reported by NevGold, prepared in accordance with Canadian Institute of Mining definitions and NI 43-101 by an independent consultant. The company states that mineralization starts at surface, with a conceptual pit-shell strip ratio expected to be less than 1:1, and that most of the gold in the resource is situated in the upper portion of a north-trending graben-hosted system. NevGold identifies four principal zones of mineralization at Nutmeg Mountain: the Main Zone, North Zone, Stinking Water Zone, and Cove Creek Zone, with the Main Zone containing most of the reported gold in the MRE. The company notes that average historical drill-hole depths are relatively shallow and that potential high-grade feeder structures typical of low-sulphidation systems have yet to be identified, indicating further exploration potential.

Project development focus and critical minerals context

NevGold’s news releases emphasize a staged project development approach at Limousine Butte, including ongoing drilling, metallurgical testwork, evaluation of historical geological databases, and preparation of initial gold–antimony Mineral Resource Estimates at Resurrection Ridge and Cadillac Valley. The company also describes a path to advancing Nutmeg Mountain toward a Preliminary Economic Assessment through additional metallurgical work and drilling of identified targets.

In multiple disclosures, NevGold references a United States Executive Order that invokes the Defense Production Act to strengthen American mineral production and reduce reliance on foreign mineral supply. The company highlights that antimony has been designated a “Critical Mineral” by the U.S. Geological Survey and the U.S. Department of Defense due to its importance in national security, technology, and clean-energy storage applications, and notes that there is limited or no domestically mined antimony supply in the United States. In this context, NevGold positions its Limo Butte project, with near-surface oxide antimony–gold mineralization and a large geological database, as aligned with broader efforts to expand domestic mineral output.
