Hawk Resources Extends Near Surface Copper Mineralisation at Utah Cactus Corridor

Drill Hole DD26CT004 Confirms Continuity and Extension of Copper Mineralisation

Hawk Resources Limited (ASX:HWK) has reported robust assay results from drill hole DD26CT004 at its Cactus copper-gold project in Utah, USA. The hole intersected a substantial near surface copper zone measuring 72.9 metres at 0.36% copper and 2.0 ppm silver starting just 18 metres below surface. This includes a higher-grade interval of 10.4 metres at 0.97% copper, 3.0 ppm silver, and 0.059% molybdenum from 78 metres depth, highlighting the presence of valuable polymetallic mineralisation.

The mineralised zone extends southeast from previous holes DD26CT003 and DD26CT005, bridging a gap in drilling between historical hole R-12 and recent drilling. The continuity of mineralisation into the historical Cactus open pit, mined to depths of 15-25 metres, suggests the deposit remains open along strike and at depth. The true thickness of the mineralised zone is estimated at approximately 44 metres, based on the drill orientation and geological interpretation.

Geological Setting and Mineralisation Style

The copper mineralisation is hosted within tourmaline-rich breccia zones developed along a northwest-trending structural corridor within the Cactus granodiorite intrusive. Sulphide mineralisation, primarily chalcopyrite, occurs as veins, blebs, and fracture fills associated with pyrite and tourmaline breccia veining. The mineralised interval is consistent in grade and style with nearby holes DD26CT003 and DD26CT005, which also intersected broad zones of copper with associated molybdenum, silver, and gold.

Molybdenum mineralisation remains highly anomalous and open along strike to both the northwest and southeast, with zones of 39.2 metres at 0.027% Mo from 42 metres depth in DD26CT004 exceeding grades seen in adjacent holes. Gold and silver are present throughout the zone, though at lower concentrations, with silver averaging around 2 ppm and occasional gold assays exceeding 0.1 g/t.

Historical Context and Exploration Potential

The Cactus Corridor, trending northwest for approximately one kilometre, links the historical Comet deposit, the Cactus mine, and the New Years prospect. Historical mining at Cactus produced 1.3 million tonnes at 2.0% copper from 1905 to 1920. Recent drilling has expanded the known mineralised footprint, with intercepts indicating potential extensions of up to 500 metres southeast towards Comet and 350 metres northwest towards New Years.

Previous drilling in the corridor includes notable intercepts such as 80 metres at 0.48% copper from surface in DD26CT003 and 71.7 metres at 0.45% copper in DD26CT005, both from the same drill pad as DD26CT004. Historical holes from the 1960s, including R-12, reported high-grade copper zones, reinforcing the prospectivity of the area. However, historical assays predate modern quality controls and are considered indicative only.

Next Steps and Drilling Plans

Hawk Resources is preparing to recommence drilling along the Cactus Corridor in July 2026, with plans for approximately 10 shallow holes spaced at 50-metre intervals between the Cactus and Comet deposits. This phase aims to better delineate the volume and grade continuity of near surface copper mineralisation and test the corridor’s potential to host a substantial resource.

Managing Director Scott Caithness emphasised the significance of the DD26CT004 results, noting the extension of mineralisation into a previously undrilled gap and the presence of higher-grade copper and molybdenum zones. The upcoming drilling campaign will be critical in defining the scale of the mineralised system and informing future resource estimation efforts.
