Geophysics and Field Program Update at White Hills Project
- Exploration programs to test copper and gold anomalies largely completed
- Passive seismic, controlled-source audio-magnetotellurics, and field mapping conducted
- New data expected to provide insights on intrusive bodies and mineralised structures
Helix Resources Limited (ASX:HLX) has provided an update on the exploration work at the White Hills Copper-Gold Project in Northern Arizona, USA. The exploration programs, which commenced in December 2025, are designed to refine geological interpretations and test the scale of copper and gold mineralisation potential at the project. The work program has largely been completed and includes a passive seismic Ambient Noise Tomography (ANT) survey, a Controlled-Source Audio-Magnetotellurics (CSAMT) survey, and field geological mapping in new road cutting exposures. The passive seismic and CSAMT datasets are expected to provide new information on the distribution of intrusive rocks, the geometry of large-scale mineralised detachment structures, and the deeper resistivity framework. Helix is now working to integrate the new geophysical data with existing geophysics, field mapping results, and historical drilling to produce a consolidated model for drill targeting. This model will support the definition of ranked drill targets for follow-up drilling in early 2026. The White Hills project has a large copper-gold soil anomaly and high-grade rock chip samples, with previous drilling targeting gold only and not fully evaluating the copper potential. The current program is designed to refine the three-dimensional architecture of the mineral system, evaluate the distribution of intrusive bodies, and define structural controls on anomalism to establish a more robust geological model.
Helix is planning a diamond drilling program to follow the geophysical surveys, focusing on the copper and gold anomalies at the Section 2 area. The drilling aims to provide information to support the evaluation of both porphyry-related and detachment-related mineralisation models, as well as provide structural information and fresh rock samples for further analysis.
