Antares Metals Unveils Promising Conglomerate Creek Exploration Results

Antares Metals Uncovers Exceptional Copper, Gold, and Silver Values at Conglomerate Creek

Antares Metals (ASX: AM5) has reported outstanding assay results from recent exploration at its Mt Isa North Copper and Uranium Project, with rock chip samples returning values up to 22.0% copper, 7.4 g/t gold and 394 g/t silver. The findings substantially enhance the prospectivity of the company's Conglomerate Creek prospect. The Antares Metals Conglomerate Creek exploration program has already shown impressive results across multiple commodities.

High-Grade Results Underscore Multi-Metal Potential

The Antares Metals Conglomerate Creek exploration program targeting geophysical anomalies has yielded exceptional results from two key areas within the prospect:

• A 450m vein system north of the main geophysical targets returned 22.0% Cu, 1.6 g/t Au and 394 g/t Ag (sample ASR0051)
• Surface sampling above geophysical targets discovered gold-rich mineralization with values of 1.1% Cu, 7.4 g/t Au and 50 g/t Ag (sample ASR0037)

These results significantly expand the potential of the project, adding substantial gold and silver values to the previously identified copper mineralization, reminiscent of other major gold system discoveries in the region.

"Our Mt Isa Copper and Uranium Project continues to return outstanding field results and gives further encouragement to systematically explore our tenement holdings for copper and uranium mineralisation," said Chief Executive Officer Johan Lambrechts. "The results from Conglomerate Creek now indicate the presence of gold and silver in addition to the strong copper potential, and enhance the prospectivity of the area."

Geological Setting and Mineralization Style

The high-grade copper-gold-silver results at Conglomerate Creek are associated with a semi-circular intrusive feature measuring 2km x 2.5km. This geological setting is particularly significant in the Mt Isa region, which hosts world-class sediment-hosted copper deposits.

Mineralization appears to be intrusion-related, with a copper-bearing vein system exhibiting classic indicator minerals including bismuth, tungsten, antimony and selenium. The combination of:

1. The vein system with high-grade copper, gold and silver
2. Geophysical anomalies suggesting a deeper intrusive source
3. Elevated indicator minerals typical of intrusion-related mineral systems

Together these factors suggest potential for a large-scale copper mineralized system driven by the Conglomerate Creek intrusion as its heat source.

Understanding Intrusion-Related Copper Systems

Intrusion-related copper systems are significant exploration targets globally. These systems form when metal-rich fluids from an igneous intrusion migrate upward along structures and precipitate metals as they cool.

The presence of indicator minerals such as bismuth, tungsten, and selenium is a characteristic signature of these systems. The radial pattern of veins observed at Conglomerate Creek, with a central splay zone up to 50m wide containing at least five separate radial veins, is consistent with the structural architecture often found above intrusion-related mineral deposits.

In intrusion-related systems, the central portions typically contain copper-dominant mineralization, while peripheral zones may contain elevated precious metals including gold and silver. The recent uranium targets in Mt Isa and the discovery at Conglomerate Creek showing both copper-dominant and gold-dominant areas align with this model.

For investors, this mineralization style may be particularly valuable as these systems can host large tonnages with multiple commodities (copper, gold, silver) that enhance project economics.

Significance of Multi-Element Results

The assay results from Conglomerate Creek are notable not only for their high grades but also for their multi-element character. Key findings include:

The consistent presence of silver alongside copper and gold adds significant potential value to the prospect. Silver values reaching nearly 400 g/t are exceptional and warrant further investigation.

The Antares Metals Conglomerate Creek exploration program has also identified elevated levels of bismuth, tungsten, antimony, and selenium—elements that frequently occur in association with intrusion-related copper-gold systems. These pathfinder elements provide additional confirmation of the intrusion-related model and may help vector towards zones of higher-grade mineralization.

Next Steps and Exploration Timeline

Antares is pursuing a systematic exploration approach across its Mt Isa North tenement holdings. Current and planned activities include:

• Continued field reconnaissance and mapping of identified prospects
• Detailed geochemical sampling to better define the extent of mineralization
• Further investigation of the identified geophysical anomalies
• Ranking and prioritization of targets for potential drill testing

The company's methodical approach aims to maximize the chances of success while efficiently managing its exploration budget. With approximately $1.3 million in cash as of June 2025, Antares is well-positioned to advance this systematic exploration program.

Investment Potential

For investors considering Antares Metals (ASX: AM5), several factors make the company an interesting proposition:

1. Multiple commodity exposure: The discovery of significant gold and silver values alongside copper provides diversification and potential economic advantages.

2. Prime location: The Mt Isa region is one of Australia's premier mining districts with established infrastructure and processing facilities.

3. Systematic approach: The company is methodically exploring its tenement holdings, building a pipeline of quality targets.

4. Upside potential: With a current market capitalization of only $3.1 million, significant value creation is possible if exploration success continues.

5. Experienced leadership: The company is led by a team with substantial mining experience, including Chairman Mark Connelly, who has a track record of creating shareholder value in the resources sector.

Prospectivity of the Mt Isa Region

The Mt Isa region where Antares is conducting its Conglomerate Creek exploration is globally recognized for its mineral endowment. The area hosts world-class deposits including:

• The Mount Isa copper-zinc-lead mine
• The Ernest Henry copper-gold mine
• The Cannington silver-lead-zinc mine

These established operations demonstrate the region's exceptional mineral potential. The geological setting at Conglomerate Creek shares characteristics with these major deposits, particularly in terms of structural controls and alteration styles.

The combination of high-grade surface samples, favorable geological setting, and geophysical anomalies suggests Antares Metals may have identified a significant mineral system at Conglomerate Creek. While early-stage, the results to date warrant continued systematic exploration.

For investors seeking exposure to copper and precious metals exploration in a tier-one mining jurisdiction, Antares Metals warrants close attention as it continues to unlock the potential of its Mt Isa North project. The area has already seen successful copper-gold discoveries by Hammer Metals and high-grade gold confirmations elsewhere, with Carnaby Resources also expanding their copper-gold presence in the region.
