Location of the Parker Project in northwest Arizona relative to the southeastern extension of the Walker Lane gold - copper trend. Refer to ASX release “MULTIPLE CONTINUOUS MINERALISED TRENDS DEFINED AT PARKER”, 12 March 2026.
The Parker Project is located in western Arizona, approximately 14 kilometres northeast of Parker, within the Buckskin Mountains Province and along the southeastern extension of the Walker Lane gold-copper trend. The project comprises 79 unpatented federal lode mining claims covering approximately 6.58 km².
Surface work has identified gold and copper results aligned with mapped and interpreted structures, supporting continued exploration and future drill targeting. All grades, dates and technical conclusions must be migrated from the current approved project page or latest release.
Historical engineering reports and Arizona Department of Mines records describe the Eagle Nest Mine as multiple structurally controlled copper-gold mineralised structures developed along contacts between quartz-porphyry intrusions and folded carbonate and sedimentary sequences. By the early to mid-20th century, several thousand feet of underground development had been completed, including shafts, tunnels, open cuts and test pits. At Eagle Nest Mine four principal shafts were reported to depths of approximately 100 feet, 200 feet and 600 feet, with ore encountered in multiple workings. Recorded production during World War I and again in the early 1940s involved shipment of copper-gold ore to Arizona smelters, with gold credits contributing materially to shipment value.

Historical documentation indicates that mining ceased in the early 1940s not due to exhaustion of mineralisation or adverse metallurgical performance, but as a consequence of labour shortages. As Federal infrastructure projects commenced in the Parker district during World War II, miners left the operation for higher-paid government employment, resulting in suspension of mining activities despite the operation having returned to profitability at the time.

On 9 April 2026, Magnum reported multiple high-grade rock chip results at the Parker Project, including up to 176g/t Au and 18.30% Cu. Results to date have shown that gold and copper anomalism is spatially aligned with mapped and interpreted structures, with a combined prospective strike length of ~5km, reinforcing the scale and coherence of the Parker surface mineral system.
