High-Resolution Magnetic Survey to Unlock Further Potential at 2.2Moz Gold Asset
Rox Resources (ASX: RXL) has completed a comprehensive airborne magnetic survey at its flagship Youanmi Gold Project as part of its strategy to unlock additional value across its extensive landholding. This exploration initiative follows the company's recently announced Mineral Resource Estimate of 2.2 million ounces at an impressive grade of 5.6 g/t gold.
The high-grade Youanmi Project, located 480 kilometers northeast of Perth in Western Australia, is emerging as one of Australia's most promising gold developments. With Rox Resources gold project exploration advancing alongside early works programs, Rox remains on track to deliver its Definitive Feasibility Study in the coming quarter.
Strategic Exploration Enhancement
Rox has taken two significant steps to advance exploration at Youanmi:
- Completion of a detailed regional aeromagnetic survey
- Appointment of leading structural geologist Dr. Melanie Finch to enhance understanding of the Youanmi system
"Following our highly successful drill programs and recent Mineral Resource Update, our exploration team has turned its attention to assessing the full potential of our extensive landholding at Youanmi," said Managing Director & CEO Phill Wilding.
"This new dataset will be used for regional target generation and enable us to better define structural controls on mineralisation to unlock significant value in upcoming drill programs."
Advanced Magnetic Surveying: Creating a Unified Dataset
The new airborne magnetic survey, conducted by MAGSPEC Airborne Surveys with support from geophysical consultants Newexco Exploration, represents a significant upgrade to Youanmi's geophysical database.
Prior to this survey, Rox had to work with a fragmented collection of datasets of varying quality and vintage. The new comprehensive survey:
- Reduces regional line separation to 50 meters over more than 100km of continuous license holding
- Features 25-meter line spacing at the Youanmi deposit area
- Was flown at a nominal height of 30 meters for maximum resolution
- Provides enhanced digital terrain and radiometric data
This unified, high-resolution dataset will dramatically improve Rox's ability to interpret structural and lithological features across both the mine site and regional scale, forming the foundation for ongoing Rox Resources gold project exploration.
World-Class Expertise: Dr. Melanie Finch's Appointment
In a significant endorsement of the project's potential, Rox has secured the expertise of Dr. Melanie Finch from the University of Melbourne to assess the structural evolution of the Youanmi shear zone and the mechanisms influencing gold deposition.
Dr. Finch brings impressive credentials to the project:
- Specialises in the formation of hydrothermal ore deposits in ductile shear zones
- Heads the University of Melbourne structural geology group
- Received the 2024 medal for Outstanding Contributions to Structural Geology and Tectonics from the Geological Society of Australia
- Awarded multiple Australian Research Council grants for her work on shear zones
Her initial work will focus on tomographic analysis, using 3D X-ray imaging of drill core to understand the major structures controlling sulphide deposition and gold positioning within the system.
In 2026, this preliminary work will support a PhD project supervised by Dr. Finch, expected to focus on the structural evolution of the Youanmi shear zone and mineralisation controls within different domains of the deposit.
Understanding Structural Controls in Gold Deposits
Structural geology plays a critical role in gold exploration and development, particularly in shear zone-hosted deposits like Youanmi. Shear zones are areas where rocks have been deformed under ductile conditions, creating pathways for mineralising fluids.
Understanding these structural controls helps exploration teams:
- Identify the most prospective areas for future drilling
- Predict the orientation and continuation of high-grade zones
- Optimise resource development and mining approaches
- Generate new exploration targets based on geological models
The combination of advanced magnetic surveying and Dr. Finch's structural expertise gives Rox a powerful toolkit for identifying new drilling targets and optimising resource development.
What are shear zones and why are they important for gold deposits?
Shear zones are planar zones in the Earth's crust where rocks have been deformed by tectonic forces, creating areas of structural weakness. These zones are particularly important for gold deposits because:
- They create enhanced permeability that allows gold-bearing fluids to move through rocks
- The deformation processes can create pressure gradients that drive fluid flow
- Chemical reactions between these fluids and surrounding rocks can precipitate gold
- Structural complexities within shear zones often create ideal traps for gold deposition
At Youanmi, the shear zone extends for over 100km, creating numerous opportunities for gold mineralisation along its length. The new magnetic survey will help identify key structures within this extensive system.
How do magnetic surveys help identify gold targets?
Magnetic surveys measure subtle variations in the Earth's magnetic field caused by different rock types and structures beneath the surface. These surveys are particularly valuable for gold exploration because:
- They can detect magnetic minerals like magnetite that may be associated with gold-bearing systems
- They can identify structural features like faults and shear zones that may host gold
- Different rock types often have distinct magnetic signatures
- Alteration related to gold mineralisation can change the magnetic properties of rocks
By flying at just 30 meters above the ground with closely spaced survey lines, Rox's new survey provides exceptionally detailed magnetic data that can reveal subtle features not visible in previous datasets.
Youanmi Gold Project: A High-Grade Development Opportunity
The Youanmi Gold Project represents one of Western Australia's most exciting gold development opportunities. Key project highlights include:
| Feature | Details |
|---|---|
| Total Resource | 12.1Mt at 5.6g/t for 2.2Moz gold |
| Location | 480km northeast of Perth, near Mt Magnet |
| Ownership | 100% Rox Resources |
| Development Stage | Definitive Feasibility Study due next quarter |
| Historical Production | Historical mining dates back to the early 1900s |
| Exploration Potential | Extensive 100km+ land package along the Youanmi shear zone |
The project's high grade (5.6 g/t gold) puts it among Australia's highest-grade undeveloped gold projects, potentially supporting robust project economics with lower processing requirements compared to lower-grade operations.
Clear Path to Development
With its Definitive Feasibility Study on track for delivery in the coming quarter, Rox is methodically advancing Youanmi toward production. The current Rox Resources gold project exploration initiatives support this development path by:
- Enhancing geological understanding to optimise mining plans
- Identifying potential resource extensions
- Building a pipeline of exploration targets across the extensive land package
- Supporting technical studies with improved geological data
"With exploration advancing in parallel with our early works program, we remain firmly on track to deliver the Definitive Feasibility Study in the coming quarter," noted Wilding.
