King River Resources (ASX:KRR) has commissioned a rapid program delivery for a new aeromagnetic survey to be flown over the historic Mindoolah gold project in WA.

The high-resolution drone-borne aeromagnetic survey will be flown over priority target areas pf the historically mined high-grade goldfield located approximately 70km north-west of Cue in the highly prospective Murchison Province.
MD, Graham Gadsby, said the company has contracted specialist geophysical contractor Magtech Surveys to commence the survey from 25 June 2026. The survey is expected to take approximately five days, with processed magnetic data and preliminary interpretation to follow shortly thereafter.
“We are excited to launch this high-resolution drone-borne survey, which marks an important step forward for the Mindoolah Gold Project,” Mr Gadsby said.
“Historically, exploration here has relied on broad regional magnetic datasets that are heavily obscured by the nearby Weld Range formations. By utilising tight 25 metre spacing at low altitudes, this modern UAV program allows us to effectively map concealed structures and resolve the intricate, cross-cutting intersections that we believe could control the high-grade gold mineralisation.
“Fieldwork begins next week, and we look forward to rapidly delivering processed data to refine our next phase of priority drill targets.”
The planned unmanned aerial vehicle, (UAV) aeromagnetic survey has been designed to deliver substantially improved spatial resolution across the project area.
Magtech Surveys will utilise a QuSpin QTFM V2 optically pumped magnetometer deployed from a drone platform at low altitude, enabling the collection of high-resolution magnetic data across the Mindoolah mining centre and surrounding target areas.
The detailed dataset is expected to improve KRR’s ability to identify subtle magnetic variations and refine the interpreted location and orientation of shear zones, cross-cutting faults, lithological contacts and potential alteration corridors that are not adequately resolved in the existing regional geophysical coverage.
KRR had previously announced it intended to complete a helicopter-borne magnetic survey across the broader Mindoolah gold project area, with survey lines planned at 50m spacing.
However, this program has been temporarily deferred due to ongoing third-party contractor delays in mobilisation and commencement.
KRR is steady at 3.1¢. Mkt cap $45.37M.
