Antares Metals Unveils Queens Gift Copper-Uranium Discovery in Mt Isa

Antares Metals Confirms Exciting Copper-Uranium Discovery at Queens Gift

Exploration activities at Antares Metals' (ASX: AM5) Mt Isa North Project have yielded a significant discovery, with visible copper mineralisation identified within uranium samples at the Queens Gift prospect. This development potentially enhances the economic prospects of the already advanced uranium resource.

Dual Commodity Potential Boosts Project Value

Antares geologists have confirmed visible copper mineralisation co-existing with uranium at the Queens Gift prospect in northwest Queensland. The discovery came during recent field reconnaissance activities designed to validate historical uranium mineralisation at the site.

The field team observed disseminated chalcopyrite (1-3% by volume) and pyrite (0.5-2% by volume) in rock samples originally collected for uranium testing, suggesting potential copper grades of 500-1000 ppm based on visual estimates.

"Our geologists continue to actively and systematically explore our tenement holdings, and we are very encouraged by the mineralisation encountered so far," commented CEO Johan Lambrechts. "The sampling and reconnaissance activities conducted at the Queens Gift resource shows that it contains zones of copper mineralisation along with the uranium previously identified and we are excited to continue evaluating and exploring this prospect."

This dual-commodity potential significantly enhances the project's economic prospects, with laboratory assay results expected within 4-6 weeks.

Queens Gift: An Advanced Uranium Resource with Growing Potential

Located approximately 77km north-northwest of Mt Isa, the Queens Gift uranium deposit represents one of Antares' most advanced exploration targets. The Antares Metals Queens Gift discovery was originally identified by Queensland Mines Ltd in 1969 and saw significant exploration work by Deep Yellow Ltd between 2006 and 2011.

Key characteristics of the Queens Gift prospect include:

• Established JORC-2004 compliant uranium resource from 2011
• 1.3km strike length with mineralisation open at depth
• Hosted in hematite-altered basalts with quartz-breccia zones
• Similar geological setting to Paladin Energy's Valhalla Uranium Deposit

The mineralisation at Queens Gift displays notable geological similarities to the Valhalla Uranium Deposit owned by Paladin Energy (ASX:PDN), with both featuring similar:

• Geological settings
• Alteration signatures (hematite, albitite, carbonate and magnetite)
• Steeply dipping mineralisation zones

Understanding Albitite-Type Uranium Deposits

The Antares Metals Queens Gift discovery represents what geologists classify as an "albitite-type" uranium deposit. These deposits form in variably altered metabasalt with intense hematite-albite and silica alteration, often with carbonate-magnetite alteration present.

What are albitite-type uranium deposits?
Albitite-type uranium deposits are uranium occurrences found in altered volcanic rocks, particularly basalts. The alteration process creates distinctive mineral assemblages where uranium minerals form in association with albite (a sodium-rich feldspar mineral), hematite (an iron oxide), and other alteration minerals.

How do these deposits form?
These deposits typically form along structural pathways such as faults or shear zones, where mineral-rich fluids can move through the rock. At Queens Gift, the mineralisation follows a general NNE-SSW shear trend, with the uranium-bearing zones dipping steeply in different directions.

What uranium minerals are present?
The primary uranium minerals in these deposits include brannerite, uraninite, and coffinite. These minerals form within the altered and brecciated (fractured) zones of the host basalt.

For investors, understanding this deposit type is important because:

1. Albitite-type deposits can host significant uranium resources
2. The presence of copper mineralisation in such deposits can enhance economic viability
3. These deposits typically follow structural trends (NNE-SSW shear trend at Queens Gift)
4. The uranium minerals are predominantly brannerite, uraninite and coffinite

This geological setting makes the Antares Metals Queens Gift discovery particularly prospective for both uranium and copper mineralisation, potentially offering multiple revenue streams from a single resource.

Strategic Exploration Plans and Timeline

Antares has outlined a clear path forward for its Mt Isa North Copper and Uranium Project, with multiple work streams advancing simultaneously:

1. Queens Gift Advancement:

   • Complete compilation of geological and geophysical data
   • Continue ground truthing through geological reconnaissance and sampling
   • Consider upgrading the existing mineral resource estimate

2. Broader Project Development:

   • Third phase of drilling planned at the Surprise Copper Prospect
   • First phase of drilling planned at the Conglomerate Creek Copper Prospect
   • Acquisition of new geophysical data on the Calton Hill Prospect

This systematic approach allows Antares to efficiently allocate resources across multiple prospective areas, maximising the potential for discovery success.

Investment Case: Strategic Position in Critical Minerals

Antares Metals presents a compelling investment case for those seeking exposure to both copper and uranium – two critical minerals essential for the global energy transition.

The company's Mt Isa North Project covers 2,003km² of prime tenure adjoining Glencore's Mt Isa Operations, positioning it in one of Australia's premier mining districts. The project area has seen limited historical exploration despite having the right geological setting for copper, zinc-silver-lead, uranium, and rare earth elements.

Why copper and uranium matter

Both copper and uranium are considered critical minerals essential for the global energy transition:

• Uranium is the primary fuel for nuclear power plants, which provide reliable, carbon-free baseload electricity. With over 60 nuclear reactors under construction globally and many countries now embracing nuclear energy as part of their clean energy strategy, uranium demand is projected to increase significantly.

• Copper is essential for all forms of electrification, renewable energy generation, and transmission infrastructure. Electric vehicles require up to four times more copper than conventional vehicles, while renewable energy systems like solar and wind use two to five times more copper than traditional power generation.

The Antares Metals Queens Gift discovery provides investors with:

1. Exposure to uranium – a critical clean energy fuel experiencing rising demand as nations expand nuclear power generation
2. Copper opportunity – essential for renewable energy infrastructure and electrification
3. Advanced exploration assets – including the Queens Gift uranium resource
4. Multiple near-term catalysts – including drilling programs and high-grade results

The recent discovery of copper mineralisation at Queens Gift potentially enhances the economic profile of what was already considered a valuable uranium asset.

Why Investors Should Follow Antares Metals

Antares Metals (ASX: AM5) has positioned itself as an emerging player in the critical minerals sector, with significant upside potential due to its strategic land position and advanced exploration assets.

The company's methodical approach to exploration, focusing on both copper and uranium, provides investors with diversified exposure to two of the most in-demand metals for the global energy transition. With multiple drilling programs planned and assay results pending from Queens Gift, there are numerous near-term catalysts that could drive share price appreciation.

The Mt Isa region is one of Australia's most prolific mineral provinces, home to world-class deposits such as Glencore's Mount Isa copper and zinc-lead mines. Antares' strategic land position, directly adjoining these operations, provides significant exploration potential in an area known for its mineral endowment.

For investors seeking exposure to the critical minerals sector, Antares offers a compelling combination of advanced assets, strategic positioning, and exploration upside in one of Australia's premier mining districts.
