Magmatic Resources Limited announced final FY2026 exploration results from the Myall Farm-in and Joint Venture Agreement Copper-Gold Project in New South Wales, funded by Fortescue under an FY2026 program budget expanded from about $3.5 million to about $3.9 million. The program comprised 16 diamond drill holes for 6,240.4 metres and a March 2026 aircore campaign of 17 holes for 1,846 metres, targeting Northparkes-style copper-gold porphyry analogues and extensions around the Corvette-Kingswood Inferred Mineral Resource Estimate of 110Mt at 0.33% CuEq. The most material outcomes were at Calais, where hole FMD0522 returned 38 metres at 0.17% Cu and 0.04 g/t Au from 324 metres and displayed alteration considered consistent with Macquarie Arc porphyry systems, and at Stingray southwest of Kingswood, where FMD0528 returned 36.3 metres at 0.16% Cu and 0.03 g/t Au from 400 metres plus 39 metres at 0.13% Cu from 166 metres, supporting the interpretation that mineralisation continues south of the existing inferred resource. Aircore drilling at Interceptor also returned 3 metres at 0.15% Cu from 111 metres in FMAC026, confirming the effectiveness of low-cost cover-basement interface testing for geochemical and geophysical anomalies. Additional encouraging but lower-tenor or more distal-style results were reported from SLR, Gemini and Calais Trend, while Sandman returned no significant result, and the company said these outcomes will guide a focused FY2027 drilling and aircore follow-up program with Fortescue.
Key Points
FY2026 exploration at the Myall FJVA Copper-Gold Project has been completed with final assay results reported by Magmatic Resources.
The Myall Project is funded by Fortescue under a farm-in and joint venture arrangement signed in March 2024, under which Fortescue may earn up to 75% for $14 million expenditure.
The FY2026 work program budget was increased from about $3.5 million to about $3.9 million with an extra $400,000 for diamond drilling.
A total of 16 diamond drill holes for 6,240.4 metres were completed across Barina, Interceptor, Gemini, SLR, Calais, Calais Trend, Sandman and Stingray.
The March 2026 aircore program comprised 17 holes for 1,846 metres, bringing the total aircore program to 42 holes for 4,169 metres.
The program targeted new geophysical and geochemical anomalies analogous to Northparkes-style copper-gold porphyry systems and extensions near the Corvette-Kingswood inferred resource.
The Corvette and Kingswood deposits host a 2023 Inferred Mineral Resource Estimate of 110Mt at 0.33% CuEq containing 293 kt copper, 237 koz gold and 2.8 Moz silver.
The standout Calais result was 38 metres at 0.17% Cu and 0.04 g/t Au from 324 metres in FMD0522.
Magmatic said alteration in Calais hole FMD0522 is consistent with Macquarie Arc porphyry mineral systems and provides useful vectors for future drilling.
The standout Stingray result was 36.3 metres at 0.16% Cu and 0.03 g/t Au from 400 metres in FMD0528.
FMD0528 also returned 39 metres at 0.13% Cu from 166 metres at Stingray.
Magmatic interpreted the Stingray drilling southwest of Kingswood as evidence that mineralisation continues beyond the current inferred resource area.
The best March 2026 aircore result was at Interceptor with 3 metres at 0.15% Cu from 111 metres in FMAC026.
SLR hole FMD0519 returned 4 metres at 0.20% Cu and 1.55 g/t Au from 336 metres, with trace bornite and K-feldspar veining noted.
Gemini hole FMD0516 returned 10.9 metres at 0.13% Cu and 0.09 g/t Au from 391 metres to end of hole.
Calais Trend hole FMD0523 returned a polymetallic interval of 2 metres at 2.8 g/t Au, 0.2% Cu, 0.7% Pb and 1.0% Zn interpreted as distal to a porphyry centre.
Sandman hole FMD0526 intersected volcanic and intrusive rocks beneath cover but returned no significant result.
Magmatic plans focused FY2027 drilling and further aircore work to follow up geochemical vectors and priority porphyry targets with Fortescue.
