Key Projects
Yalgoo Property
Tempest’s largely unexplored and 100-percent-owned Yalgoo property covers more than 1,000 square kilometres and is highly prospective for gold, base metals and iron with world-class potential. It is located four hours from Perth, close to major infrastructure and adjacent to world-class mines, including Golden Grove, Deflector, Mt Gibson, Minjar, Rothsay and Mt Mulgine.
The Remorse Target is a 5 km long exploration target where TEM completed an initial 4,005 meters of drilling in 2024 and identified a significant magnetite iron-ore deposit. The target also remains highly prospective for base metals.
Tempest also has a number of compelling exploration targets across the 1,000 sq km project including the Sanity target which is highly prospective for gold, with rock chip samples returning 7 grams per ton (g/t) gold, 0.2 percent copper, and more than 60 percent iron.
Mt Magnet
The 100-percent owned Mt Magnet project spans more than 20 square kilometres located within a world-class mining district and is 5 kilometres from a processing facility. A prolific mining destination with at least 6 million ounces of gold produced to date, the project is surrounded by multiple large-scale gold mines currently in operations, including Ramelius’ (ASX:RMS) Mt Magnet operations and Spartan’s (ASX:SPR) Dalgaranga. The project contains multiple drill targets, of which Wrangler will be a key focus of near-term work.
Elephant
The Elephant project is a 194 square kilometre property in the prolific Fraser Range region with large geological structures and multi-million-ounce targets. The project area itself has strong magnetic anomalies and an 8-kilometre gold in soil geochemical anomaly which could represent a large subsurface gold system.
Five Wheels
The 100-percent owned, 266-square-kilometre Five Wheels project is geologically similar to Rumble Resources’ zinc-lead-copper discoveries and sits within the boundaries of the Earaheedy Basin in Western Australia, a mineralised sedimentary basin. A major geophysics program is planned for the project, co-funded by the government.

NevGold
Investor Insight
With a sharp focus on discovery and resource growth, NevGold presents a compelling investment opportunity as an undervalued gold and critical metals explorer with projects in Nevada and Idaho—two of the world’s top mining jurisdictions.
Overview
NevGold (TSXV:NAU,OTCQX:NAUFF,FSE:5E50) is focused on discovering and growing a multi-million-ounce gold-equivalent resource base across Nevada and Idaho in the US. With a lean market capitalization of under C$50 million and a pipeline of highly prospective oxide and porphyry assets, the company is positioned for a significant valuation re-rate over the next 12 to 18 months as it executes on its resource growth and de-risking strategy.
The company is rapidly advancing toward its goal of defining a 5 Moz+ gold-equivalent resource base by Q4 2025, anchored by its flagship Limo Butte project – one of North America’s rare oxide gold-antimony systems – and its gold resource at Nutmeg Mountain, along with early-stage copper potential at Zeus.
The Limo Butte project is a high-grade oxide gold-antimony system in Nevada with strong analogues to Carlin-style mineralization and excellent near-surface drill results. Nutmeg Mountain in Idaho is an advanced-stage, heap-leach gold project with 1.3 Moz in defined resources and favorable metallurgy. Zeus, an early-stage copper project staked in 2023, provides blue-sky porphyry exploration potential in a district that has already attracted major interest, including a C$30 million investment by Barrick Gold in a neighboring property.
NevGold is actively executing on drill programs, metallurgical studies, and resource updates across all three projects, fully funded through its recent capital raise. The company is well positioned to benefit from rising gold and copper prices, increasing strategic demand for antimony, and a growing appetite among major mining companies for high-quality, undervalued juniors – all under the leadership of a proven team with deep expertise in mine development and M&A.
Company Highlights
- Multi-million-ounce Target: NevGold is on track to define 5+ Moz gold equivalent in combined resources at Limo Butte and Nutmeg Mountain by Q4 2025.
- Gold+Antimony Critical Metals Advantage: Limo Butte is emerging as a significant near-surface oxide gold-antimony system – one of only two of its kind in the United States.
- Substantial Resource Base: Nutmeg Mountain contains a 2023 NI 43-101 compliant oxide gold resource of 1.28 Moz (indicated + inferred), with strong exploration upside and favorable heap-leach characteristics.
- District-scale Copper Exposure: Zeus offers early-stage copper-gold-molybdenum potential in a highly active porphyry belt, adjacent to a Barrick-backed discovery.
- Strategic Location, Strategic Commodities: All projects are located in mining-friendly jurisdictions with excellent infrastructure, low geopolitical risk, and growing US demand for domestic gold and critical mineral supply.
- Fully Funded Growth: Recent C$6 million financing supports 2025 drill campaigns, metallurgical testwork, and updated NI 43-101 estimates across the portfolio.
- Tight Capital Structure & Strong Support: Backed by strategic shareholders including GoldMining and McEwen Mining.
- Significant Valuation Gap: Trading at a fraction of peers such as Perpetua Resources (~C$1.7 billion), despite similar resource and jurisdictional advantages.
Key Projects
Limo Butte Project
The Limo Butte Project is NevGold’s cornerstone development asset, located in eastern Nevada within a prolific Carlin-style geological setting. The project encompasses 1,724 hectares consisting of 210 unpatented claims, 12 patented claims and private land leases. Historically explored in the 2000s, a 2009 non-43-101-compliant resource estimate outlined 241 koz of gold in the measured and indicated category (0.78 g/t gold) and 51 koz in the inferred category (0.70 g/t gold).
In 2025, NevGold re-assayed approximately 50 legacy drillholes and completed more than 5,000 meters of new RC drilling across the Resurrection Ridge and Cadillac Valley zones, revealing a substantial near-surface gold-antimony mineralized footprint.
Notably, recent drill intercepts returned thick oxide intervals, including:
- 1.11 g/t gold and 0.30 percent antimony (2.46 g/t gold equivalent) over 86.9 m, including 1.83 g/t gold and 0.87 percent antimony (5.75 g/t gold equivalent) over 12.8 m
- 2.26 g/t gold and 0.32 percent antimony (3.69 g/t gold equivalent) over 22.3 m
- 1.20 g/t gold and 0.64 percent antimony (4.07 g/t gold equivalent) over 54.9 m
These results confirm strong grade continuity and a positive spatial correlation between gold and antimony mineralization. Importantly, historical assays had a detection limit of 1 percent antimony, meaning actual antimony content in several zones is likely underreported.
Mineralization begins within 20 meters of surface, supporting low-strip, open-pit mining scenarios.
Metallurgical test work is underway, evaluating flowsheet options for gold and antimony recovery. A conceptual flowsheet includes gravity concentration, flotation and leaching stages to produce marketable gold and antimony products, including potential for antimony metal recovery via roasting.
NevGold aims to complete a maiden NI 43-101 compliant gold-antimony resource estimate by Q4 2025, setting the foundation for future economic studies.
Nutmeg Mountain Project
Nutmeg Mountain is an advanced oxide gold project located 80 km northwest of Boise, Idaho. The project benefits from exceptional infrastructure, road access and proximity to water and power. NevGold’s 2023 NI 43-101-compliant mineral resource estimate defined 1.01 Moz of gold in the indicated category (51.7 Mt @ 0.61 g/t gold) and 275 koz inferred (17.9 Mt @ 0.48 g/t gold), using a 0.30 g/t cut-off.
Mineralization starts at surface and exhibits strong lateral and vertical continuity. The deposit is hosted in volcanic and sedimentary units, with mineralization controlled by both lithological and structural features. The pit-constrained resource has a strip ratio of less than 1:1, highlighting the project’s potential for low-cost, bulk tonnage heap leach development. Additional drilling has confirmed the presence of higher-grade core zones (1 to 2 g/t gold), as well as potential feeder structures below the 2023 pit shell.
Current work comprises approximately 2,500 meters of RC drilling, metallurgical test work and an updated MRE planned for late 2025. Exploration targets include untested lateral extensions and high-grade feeder structures at depth. Nutmeg Mountain compares favorably to peer heap-leach projects across the Western US in terms of grade and strip ratio. It offers near-term development optionality in a mining-friendly jurisdiction and is a key contributor to NevGold’s goal of surpassing 5 Moz in gold-equivalent resources.
Zeus Copper Project
Zeus is an early-stage copper-gold-molybdenum exploration asset located on the Hercules Copper Trend in western Idaho. The project spans 29 sq km and shares similar geologic features with Hercules Metals’ Hercules Project (TSXV:BIG), which received a C$30 million strategic investment from Barrick Gold in 2023.
Zeus sits at the structural intersection of the Olds Ferry and Izee terranes, and hosts Triassic to Jurassic intrusives associated with porphyry-style mineralization. Geological mapping and surface sampling have revealed two priority targets:
- Poseidon: 2.4+ km copper-gold-molybdenum soil anomaly with coincident structural and rock chip indicators
- Thorn Springs: 1+ km copper-gold-molybdenum soil anomaly with interpreted intrusive-hosted alteration
Soil surveys were completed in early 2025, and geophysical work is ongoing to refine drill targeting. Initial drilling is anticipated by late 2025. With no prior modern exploration, Zeus offers blue-sky potential for a significant copper discovery in a highly prospective but underexplored belt. Zeus enhances NevGold’s exposure to critical minerals and provides optionality in the copper sector – particularly relevant given tightening global copper supply and increasing US strategic interest in domestic copper sources.
