Arrow Minerals has completed a gravity survey across three targets at its Yarraloola Copper Project in the Pilbara region of Western Australia (WA).
The company has also secured funding from the WA Government’s Exploration Incentive Scheme (EIS) for a detailed electromagnetic (EM) survey at the site.

It conducted an infill gravity survey over 791 stations targeting the Ava, Fraser and Mr Thomas areas, aimed at refining exploration targets for drilling planned later in 2026.
The gravity survey is set to supplement previous magnetic and electrical geophysical studies conducted near historical workings at Yarraloola.
The EIS grant supports the next phase of exploration, which includes an EM survey intended to detect new copper mineralisation and characterise known deposits.
Planned techniques comprise induced polarisation and the fixed‑loop electromagnetic method, with the goal of identifying any massive sulphide bodies adjacent to existing mineralisation.
Results from the EM survey will be integrated with both magnetic and gravity data to inform the final selection of drilling targets.
The company, in conjunction with geoscience consultant Newexco, has identified three primary drill targets at Fraser, Ava and the area around the historical Yarraloola Copper Mine.
Arrow also intends to generate further targets in the northern (Mr Thomas) and southern zones through supplementary ground geophysics and, where appropriate, geochemical sampling.
Yarraloola lies approximately 80km east of Onslow, and is accessible via gravel roads from the North West Coastal Highway.
The copper project includes historical mine workings and recent gold findings at surface, with past drilling revealing mineralisation containing copper, silver, lead and zinc.
In April this year, Arrow Minerals entered into a sale and purchase agreement to acquire an 80% interest in the Yarraloola Copper Project.
Shareholders gave their approval for the acquisition on 17 June 2026, with the transaction finalised on 24 June 2026.
The company is currently reviewing and expanding its 2026 work programme, and preparing to engage contractors and consultants for upcoming exploration activities.
