Promising New Discovery Opens Second Exploration Front
Magmatic Resources (ASX:MAG) has announced a potential new copper-gold discovery at its Myall Project in New South Wales, with initial drilling results revealing significant mineralisation across multiple targets. This Magmatic Resources copper-gold discovery adds another promising asset to the company's growing portfolio in a region known for world-class deposits.
The company's fully funded Farm-in and Joint Venture Agreement (FJVA) with Fortescue (ASX:FMG) has delivered early success with drill hole FMD0504 at the Calais target intersecting 10.8m at 0.39% copper and 0.07 g/t gold from 197m to the end of the hole. This significant intersection was part of a broader zone of 42.8m at 0.19% copper and 0.03 g/t gold.
Notably, this initial drilling at Calais was conducted over 100m from the nearest historical aircore hole and tested a coincident northwest trending aeromagnetic high and a substantial 500m by 600m geochemical anomaly. The mineralisation remains open in all directions and at depth, with planning already underway for follow-up drilling.
Magmatic's Managing Director David Richardson described the significance of the find: "The mineralisation intersected at Calais has opened up a second exploration front within the Myall FJVA Project. A straight-off-the-bat intersection of 10.8m at 0.39% Cu, 0.07 g/t Au at the end of the hole on a conceptual underexplored target shows the potential of the Tier 1 Myall FJVA Project to deliver a major Cu-Au porphyry deposit."
Corvette-Kingswood Mineralisation Extended
In addition to the Calais discovery, drilling results have extended the known mineralisation at the Corvette-Kingswood Resource area. At Corvette West, hole FMD0501 intercepted 12m at 0.58% copper and 0.04 g/t gold from 289m within a broader zone of 67m at 0.22% copper and 0.02 g/t gold.
Another significant result came from hole FMD0502 at Corvette, which returned 7m at 0.30% copper and 0.02 g/t gold from 179m within 37.7m at 0.16% copper and 0.01 g/t gold. This hole was drilled 200m south of the existing Corvette resource area, successfully extending the mineralisation further to the south.
These results have expanded the search space at Corvette-Kingswood to over 2km in length, of which only approximately 15% has been tested to date, highlighting the significant exploration potential remaining at the project.
Understanding Porphyry Systems: Key to Unlocking Value
Porphyry copper-gold deposits are among the world's largest sources of copper and can provide economical mining operations due to their large size, despite often containing relatively low-grade ore. Understanding porphyry and epithermal deposits' formation and impact is crucial for companies operating in this space, as these geological systems often yield substantial long-term operations.
These deposits typically form in clusters around intrusive igneous systems, making any initial discovery potentially significant. Furthermore, the rising global demand for copper has created favourable market conditions for new discoveries, with analysts exploring economic factors behind the copper rally that has supported mining company valuations.
The Myall Project is targeting mineralisation similar to the Evolution Mining owned Northparkes copper-gold mine located 60km south of the project. Northparkes has been in operation for over 30 years and consists of a cluster of 22 porphyry systems, providing a model for the potential at Myall.
The geological signature at Myall suggests similar characteristics to the Northparkes district, particularly at the Corvette-Kingswood area where mineralisation is associated with magnetite-altered brecciated diorite in proximity to the Corvette monzodiorite unit, which has been interpreted to extend for over 2km north-south based on geophysical data and widely spaced drilling.
Project Overview and Strategic Importance
The Myall FJVA Project is part of Magmatic Resources' broader portfolio in the prolific East Lachlan region of New South Wales. This region boasts an impressive mineral endowment of more than 80 million ounces of gold and 13 million tonnes of copper, hosting major operations such as Newmont's Cadia Valley District, Evolution Mining's recently approved Cowal Gold Operation extension, and the Northparkes copper-gold mine.
In July 2023, Magmatic Resources announced a Maiden Mineral Resource estimate at Corvette-Kingswood of 110 million tonnes at a grade of 0.33% copper equivalent, containing 293,000 tonnes of copper, 237,000 ounces of gold, and 2.8 million ounces of silver, equating to 354,000 tonnes of copper metal-equivalent.
The Farm-in and Joint Venture Agreement with Fortescue, executed in March 2024, provides funding of up to $14 million over six years to earn up to a 75% interest in the project. This partnership represents a significant vote of confidence in the project's potential, with Fortescue also becoming a cornerstone investor in Magmatic Resources, currently holding a 19.9% stake.
Future Exploration Plans
Seven holes of a planned thirteen-hole drill program have been completed to date, with further drilling planned for the second quarter of 2025. The remaining six holes will target regional eastern prospects, with applications already submitted for four of these holes.
The most immediate priority will be follow-up drilling at Calais to better define the extent of the newly discovered mineralisation, which ended in high-grade material. The 500m by 600m footprint at Calais represents a target area comparable in size to the footprint of the Northparkes deposits, highlighting its potential significance.
Market Implications of the Magmatic Resources Copper-Gold Discovery
The timing of this discovery aligns well with growing global demand for copper, particularly as the world transitions toward green energy. Similar to Rio Tinto's Rincon Lithium expansion's impact on clean energy, copper discoveries have strategic importance for the renewable energy and electric vehicle sectors.
For investors interested in the mining sector, this Magmatic Resources copper-gold discovery represents the type of early-stage opportunity that could deliver significant returns if the resource is further defined and developed.

Why Investors Should Follow Magmatic Resources
Magmatic Resources has positioned itself as an emerging player in the copper-gold exploration sector, with significant advantages:
1. Strategic location in one of Australia's premier copper-gold districts with proximity to established mining operations
2. Multiple exploration fronts now open with the Calais discovery complementing the established resource at Corvette-Kingswood
3. Strong backing from major industry player Fortescue providing both financial and technical support
4. Experienced management team with a track record of discovery and development
5. Established resource base with the 354,000 tonne copper-equivalent resource at Corvette-Kingswood providing a solid foundation for growth
The recent Magmatic Resources copper-gold discovery at Calais, combined with the extension of mineralisation at Corvette-Kingswood, demonstrates the significant exploration potential at Myall. With copper demand expected to increase substantially due to electrification and renewable energy trends, Magmatic's advancing copper-gold projects place it in an excellent position to benefit from these market dynamics.
As exploration continues and the full extent of mineralisation at both Calais and Corvette-Kingswood becomes better defined, Magmatic Resources represents an intriguing opportunity for investors seeking exposure to copper and gold exploration success in a tier-one mining jurisdiction.
