Altitude Minerals Acquires W-Project Nevada Gold-Silver Epithermal System

Altitude Minerals Secures Second Nevada Gold-Silver Project with Compelling Untested Depth Potential

Altitude Minerals Ltd (ASX: ATT) has announced the acquisition of an exclusive Option to Purchase the W-Project, a gold and silver epithermal system located near Winnemucca in Nevada, USA. The Altitude Minerals W-Project Nevada gold-silver acquisition marks the company's second precious metals project secured in what is widely regarded as the world's premier gold-mining jurisdiction, adding a target with a well-documented historical drilling record, outcropping vein systems, and — critically — significant untested depth potential that previous explorers never effectively pursued.

The announcement carries genuine strategic weight. Historical drilling returned results including 37m @ 1.30 g/t Au and 9.8 g/t Ag from 31m, and 40 of 43 drill holes intersected gold mineralisation, with 7 ending in open mineralisation. However, the company's own geological interpretation suggests the most prospective targets — high-grade feeder veins near the boiling zone — were never properly tested. That gap between what was drilled and what remains untested is the core of the investment case here.

The W-Project at a Glance

Deal Terms: Low-Cost, Staged, and Flexible

One of the more attractive structural features of this acquisition is the financial architecture. Altitude has secured the W-Project on staged, low-cost terms that allow the company to maintain optionality at each annual decision point.

The deal is structured as an exclusive Option to Purchase with vendor MinQuest Ltd, with the following payment schedule:

Note: ATT share issues are subject to future shareholder approval.

Key terms investors should note:

• Altitude can walk away at any annual decision point — there is no obligation to continue
• Overspend on work commitments carries forward to subsequent years
• Altitude can elect to purchase outright early for a combined US$990,000, less any annual Option payments already made
• A 3% Net Smelter Royalty (NSR) is granted to MinQuest, with a buydown provision of US$1.0m per 1% (reducing to a floor of 1%)
• The initial Option payment and first-year minimum work commitment are funded from existing company funds
• The BLM unpatented mineral claims are fully granted and allow all forms of exploration, including drilling

What the Historical Drilling Actually Tells Us

Between 1987 and 1992, three separate exploration groups — WX Syndicate, Bow Valley, and Santa Fe — drilled 43 holes across the W-Project. The results were broadly positive, but the company's geological review reveals a recurring problem with that historical campaign: the drilling was too shallow and too focused on the southern end of the system to test the most prospective structural targets.

Selected Significant Historical Intersections

The 1987 campaign drilled 31 holes averaging only 72 metres in depth — largely focused on the southern end of the vein. The 1992 Santa Fe campaign added 12 deeper holes averaging 258 metres, targeting the northern zone as the vein dipped beneath cover.

Furthermore, the company's structural interpretation now suggests that the typical high-grade feeder zones and boiling horizons — the geological sweet spots in an epithermal system — were not effectively intersected by any of this historical work. Seven holes ending in open mineralisation is particularly notable: this is a direct geological signal that depth extensions remain untested.

Managing Director Duncan Chessell commented: "The W-Project has near-surface, widespread low-moderate gold mineralisation identified in historical drilling, next to a thick quartz/calcite vein system. However, the typical high-grade feeder veins typical of an epithermal gold system have not been effectively tested. Located in Nevada, the world's leading mining jurisdiction, and secured on low-cost, staged terms, the W-Project is a strong addition to Altitude's growing Nevada portfolio."

Understanding Epithermal Gold Systems — Why Does the Depth Matter?

What is a low-sulphidation epithermal system?

Epithermal gold deposits form at relatively shallow depths in the earth's crust, typically between 50m and 600m below the surface, where hot, metal-rich fluids migrate upward through fault systems and cool as they approach the surface.

In low-sulphidation systems — the type present at the W-Project — gold tends to concentrate at a specific zone called the boiling zone. This is the depth at which pressure drops enough to cause the fluid to flash to steam, triggering a rapid change in chemistry that forces gold to precipitate out of solution and deposit into veins.

Why Does This Matter to Investors?

The boiling zone is where the highest-grade gold mineralisation is found. It sits at a specific depth range and is often associated with a distinctive set of veins called feeder veins. Historical drilling at the W-Project intersected broad zones of lower-grade gold in the shallower portion of the system.

Consequently, the company's geological interpretation indicates these zones sit above the boiling zone, and that the feeder veins — which would be expected to carry significantly higher grades — were not effectively drilled. This creates a clear, testable hypothesis for the upcoming drill programme.

Glossary of Key Terms

Nevada: The Geology and the Address Both Matter

The W-Project's location in Nevada is not simply a jurisdictional checkbox. Nevada consistently ranks as the world's #1 mining jurisdiction according to the Fraser Institute's annual survey — a distinction based on the combination of geological prospectivity and investment-friendly regulatory environment.

The Northern Nevada Rift corridor where the W-Project sits has produced some of the most significant gold deposits in the Americas. Nearby reference points include:

The W-Project is geologically positioned on the western margin of the NNR, sub-parallel to the Battle Mountain–Eureka Trend. The proximity to producing and advanced-stage operations speaks directly to the real-world potential of the mineralising system.

In addition, the project is exceptionally well-located for exploration. At 8km from the mining city of Winnemucca with year-round paved road access, a local mining workforce, and available services, the project carries minimal logistical friction.

What Happens Next: 2026 Work Programme

Altitude's immediate focus is on target validation before initiating an RC drilling programme. The planned work is methodical and designed to maximise the quality of drill targets before committing drilling capital.

1. Geophysics surveys — Close-spaced magnetics and Controlled Source Audio Magneto Telluric (CSAMT) surveys to define structural controls, refine the position of the N-S and NW vein intersections, and identify the most prospective depth targets
2. Geological mapping — Ground-truthing structural interpretations from the historical data review
3. Drill target ranking — Prioritisation of targets based on the integrated geophysics and mapping results
4. RC drilling — Objective to be drill-ready by Autumn (USA) 2026
5. Programme integration — Potential to combine field and drilling programmes with the Firenze Project for logistical and cost efficiencies

The 2026 geophysics programme will be a key near-term catalyst for investors to monitor. Success here would substantially de-risk the first drill targets and set up what could be a meaningful exploration event.

The Investment Thesis: Two Projects, One Nevada Portfolio

Altitude is now assembling a multi-project Nevada portfolio structured around a consistent geological thesis — identify undertested epithermal systems in a proven jurisdiction, secure them on low-cost terms, and apply modern exploration methods to test the depths that historical explorers overlooked.

Several factors underpin why this Altitude Minerals W-Project Nevada gold-silver acquisition strengthens the investment case:

• Untested depth in a proven system: The W-Project is not a grassroots prospect. It has a substantial historical drilling record showing gold mineralisation across 40 of 43 holes, over a 950m x 500m area. The key question — do high-grade feeder veins exist at depth? — remains genuinely open, and modern geophysics offers a credible path to answering it.

• Low financial exposure, high optionality: The staged deal structure means Altitude is not committing to the full acquisition cost upfront. The initial commitment is funded from existing cash, and each year represents a fresh decision point. If early results are disappointing, the company can exit. If they are compelling, it can accelerate.

• Complementary portfolio: The W-Project sits in the same region as the Firenze Silver & Gold Project, creating genuine operational synergies — combined field teams, shared geophysics programmes, and integrated drilling campaigns. This is cost efficiency built into the asset base.

• Jurisdiction quality: Nevada's regulatory framework for exploration and mining is well-established, BLM claims are fully granted, and the company's legal advisors have independently verified tenure. Drilling permits will need to be obtained from BLM, which the company notes should not be unreasonably withheld.

• Second opportunity target: Beyond the high-grade epithermal vein target, historical drilling has defined a separate opportunity — a broad, flat-lying zone of low-to-moderate grade gold mineralisation across a 950m x 500m area that could be amenable to open-cut heap-leach operations. No resource is suggested at this stage, but the optionality is noted.

Why Investors Should Keep Watching Altitude Minerals

Altitude is executing a disciplined acquisition and exploration strategy — identifying well-located, historically drilled projects where the original work was geologically incomplete, securing them on low-cost staged terms, and applying modern methods to test the actual high-value targets. The W-Project is the second Nevada asset assembled on this basis.

The near-term catalysts are concrete and measurable: geophysics results will either confirm or refine the structural model, and by Autumn 2026 the company aims to be drill-ready. First drill results from this Altitude Minerals W-Project Nevada gold-silver acquisition — particularly any intersection of the feeder vein zone at depth — would represent a significant value inflection point.

The combination of a prospective geological address, a well-documented historical dataset with clear gaps, a flexible and low-cost deal structure, and the operational synergies with Firenze creates a compelling setup for investors willing to follow the exploration story as it develops.

Key Takeaway: "Altitude Minerals has built a two-project Nevada gold-silver portfolio secured on staged, low-cost terms in the world's top-ranked mining jurisdiction. With historical drilling confirming widespread gold mineralisation at the W-Project but leaving high-grade feeder vein targets untested at depth, the upcoming 2026 geophysics and drilling programme represents a genuine discovery opportunity. Investors should watch closely as the company moves toward drill-ready status by Autumn 2026."
