Empire Resources Accelerates Copper-Gold Exploration at Yuinmery Project

Empire Resources Completes Strategic Drilling Program at Yuinmery Copper-Gold Project

Empire Resources Limited (ASX: ERL) has successfully completed a significant reverse circulation drilling program at its Yuinmery Copper-Gold Project in Western Australia, targeting multiple prospective areas for copper-gold and gold-only mineralisation.

Comprehensive Drilling Campaign Tests Multiple High-Potential Targets

Empire Resources has announced the completion of an extensive drilling program at its Empire Resources Yuinmery Copper-Gold Project, located approximately 470km northeast of Perth. The program, completed on June 27, comprised 21 reverse circulation (RC) drill holes totaling 2,593 meters across six prospective areas.

The drilling campaign targeted multiple prospects including:

• YT01
• YT12
• YT19
• Magnetic Hill
• Main Road
• Marcus-Augustus

This strategic drilling effort follows up on previous RC drilling completed in March 2025 and expands testing to additional copper-gold targets within the project area. All samples have been submitted to Intertek Minerals for analysis, with results expected in the coming weeks.

Understanding VMS Deposits: The Geological Significance of Yuinmery

The Empire Resources Yuinmery Copper-Gold Project is geologically significant as it hosts Volcanic Massive Sulphide (VMS) copper-gold mineralisation. Understanding VMS deposits is crucial as they are important sources of copper, zinc, lead, gold, and silver, typically formed in submarine volcanic environments.

What are VMS Deposits?

VMS deposits form when hot, metal-rich hydrothermal fluids are released into ocean water through faults and fractures, typically associated with underwater volcanic activity. When these hot fluids (which can reach temperatures of 350°C) mix with cold seawater, metals precipitate on the seafloor, forming massive sulphide deposits.

Why VMS Deposits Matter to Investors

VMS deposits are particularly attractive for several reasons:

• Polymetallic nature: They typically contain multiple valuable metals (copper, gold, zinc, lead, silver)
• High-grade potential: VMS deposits can contain high-grade zones
• Cluster formations: They often occur in clusters, meaning one discovery can lead to multiple deposits
• Economic viability: Many VMS deposits are economically viable even at moderate sizes

The polymetallic nature of VMS deposits at Yuinmery's Just Desserts exemplifies these characteristics, with its JORC 2012 Inferred Resource of 2.52Mt at 1.31% Cu, 0.49g/t Au and 1.76g/t Ag (using a 0.5% Cu cut-off).

Strategic Position Within Established Geological Setting

The Yuinmery Project's geological setting occupies a strategic position within the eastern portion of the Archaean Youanmi greenstone belt. The project area lies between two significant structural features:

• The Youanmi Shear zone (western boundary)
• The Yuinmery Shear zone (eastern boundary)

The geological setting includes altered chloritic felsic and intermediate volcanic units with minor tholeiitic and ultramafic volcanics, BIF, and chert. Crucially, the volcanic units contain intercalated strongly sulphidic cherty sediments, which host the VMS copper-gold mineralisation.

The southern area of the project covers the southern closure of a northerly plunging syncline, with a prominent north-south foliation overprinting many of the rocks in the project area. This geological setting provides multiple exploration targets with excellent potential for additional discoveries.

Empire's Future Development Path

Empire Resources is positioning itself as an emerging player in the gold and copper exploration sector with a focused portfolio of three highly prospective projects in Western Australia:

1. Yuinmery Copper-Gold Project: 470km northeast of Perth in the Youanmi Greenstone Belt
2. Nanadie Copper-Gold Project: Southeast of Meekatharra in the Murchison Region
3. Penny's Gold Project: 45km northeast of Kalgoorlie in the Eastern Goldfields Region

The company's immediate next steps include:

• Analysis of samples from the recently completed drilling program
• Integration of new data with existing geological models
• Refinement of targets for follow-up drilling
• Potential resource expansion at the Just Desserts deposit

With an experienced team focused on exploration, development, and financial expertise, Empire is working toward developing a sustainable and profitable mineral business through direct exploration and innovative exploration strategies.

"Empire Resources is committed to systematically exploring the full potential of our Yuinmery Copper-Gold Project through targeted drilling programs. The completion of this extensive campaign represents another important step in our exploration strategy," states Michael Ruane, Non-Executive Chairman of Empire Resources.

Investment Case: Why Empire Resources Deserves Attention

Empire Resources presents a compelling investment opportunity for several key reasons:

1. Advanced Copper-Gold Project with Established Resource

The Yuinmery Project already hosts the Just Desserts VMS deposit with a JORC 2012 Inferred Resource, providing a solid foundation for potential development or expansion.

2. Strategic Commodity Exposure

The company offers exposure to both copper and gold – critical metals for the energy transition and economic uncertainty, respectively:

• Copper: Essential for electrification, renewable energy, and EV manufacturing
• Gold: Traditional safe-haven asset during economic uncertainty

3. Multiple Projects and Exploration Upside

With three distinct projects across Western Australia, Empire offers investors multiple avenues for value creation through new discoveries or resource expansions.

4. Experienced Management

The company is led by a team with proven expertise in exploration, development, and financial management, positioning it well to advance its projects effectively.

5. Active Exploration Program

The recently completed drilling campaign demonstrates management's commitment to systematically exploring and developing the company's assets.

Why Investors Should Keep Empire Resources on Their Watchlist

Empire Resources represents an opportunity to invest in a focused explorer with established resources and significant exploration upside. The company's strategic focus on copper and gold provides exposure to both the clean energy transition (copper) and economic hedging (gold).

With samples from the recent drilling program at the lab for analysis, investors should watch closely for upcoming results that could provide catalysts for share price appreciation. The company's systematic approach to exploration across multiple prospects indicates a well-planned strategy to unlock value across its project portfolio.

The established resource at Just Desserts provides a solid foundation, while the broader exploration potential across multiple targets offers significant upside potential. As Empire continues to advance its understanding of the Empire Resources Yuinmery Copper-Gold Project's geology, there is strong potential for resource growth and new discoveries.

Key Takeaway:
Empire Resources has positioned itself as an emerging player in the copper-gold space, with an established resource base and active exploration program across multiple highly prospective projects in Western Australia. With results pending from its latest drilling campaign and strong commodity price fundamentals, the company offers investors exposure to both the critical minerals needed for the clean energy transition and traditional precious metals.
