USA — Hawk Resources Limited (ASX: HWK) has announced significant findings from a review of induced polarisation (IP) geophysical survey data in the Cactus copper-gold district of Utah.
The analysis has revealed high-priority resistivity and chargeability anomalies that coincide with magnetic and soil geochemical anomalies, potentially indicating new copper targets.
The review highlighted several promising areas:
- Cactus Deep Target: A resistivity low anomaly extends 400 metres beyond the known Cactus deposit, suggesting potential lateral extensions of mineralisation.
- CZ-1 Target: Located in the Copperopolis Zone, this target features a prominent 100 Ωm resistivity low anomaly at a structural intersection, coinciding with the district’s most intense magnetic low.
- N-1 Target: In the Northern Zone, this area shows 30mV and 50mV chargeability high anomalies coincident with magnetic lows, structures, and copper soil anomalies up to 875ppm.
- Northern Intrusive Target: Adjacent to N-1, this target exhibits a +50mV chargeability anomaly and is associated with several structurally controlled magnetic lows and copper soil anomalies.
- CZ-5/SZ-1 Target: A 60mV chargeability anomaly sits between the Sigmoid and Copperopolis Zones, beneath copper soil anomalies up to 1,000ppm.
Scott Caithness, Managing Director of Hawk Resources, highlighted the importance of these findings, stating: “Hawk’s targeting criteria for copper exploration in the Cactus copper-gold district has been further enhanced by the induced polarisation data where resistivity and chargeability anomalies are associated with magnetic low and copper in soil anomalies plus structures.”
The exploration signature of the historical Cactus and Comet copper-gold deposits now includes resistivity low anomalies, which are attributed to electrically connected sulphide mineralisation.
These anomalies coincide with alteration-related magnetic lows, anomalous copper in soils, and structures interpreted from magnetic data.
Hawk Resources plans to integrate all geophysical, geological, and soil data to design its 2025 drilling program.
The company aims to use this comprehensive dataset to rank targets for future exploration in the Cactus district.
This development represents a significant step forward in Hawk Resources’ exploration efforts in the Cactus copper-gold district, potentially leading to new discoveries and expansion of known mineralisation zones.
