King River Resources has uncovered a high-grade soil anomaly of 231.8 ppb gold at the Golden Gate prospect on the eastern side of its Mindoolah project in Western Australia’s Murchison province.
The result came from an UltraFine+ soil sampling program that the company says has defined several coherent gold trends across the tenure, closely aligned with interpreted structural corridors, magnetic features and key geological contacts.
Golden Gate sits adjacent to historical mine workings and mapped quartz veining, and King River reports the mean concentration of elevated samples in the eastern zone is 21ppb gold, about ten times the normal background of 2ppb.
On the western side, the Le Soleil-Demagnetised corridor returned soil results up to 69.9 ppb gold and a mean of elevated samples of 27ppb, roughly five times background, further expanding targets for follow-up drilling.
Those new geochemical data will be used to refine targets for King River’s large phase-two drilling program, which totals 11,000-metre of reverse circulation drilling and is currently active across Mindoolah.
Part of the program involved deeper testing beneath the historical Excelsior open pit, where earlier drilling recorded 4 metres at 9.3 g/t gold from 33 metres. A recent 3,252-metre campaign at Excelsior has been completed and all samples have been sent to the laboratory for assay.
The rig has moved to the Le Soleil-Demagnetised target corridor following the Excelsior program, and an aeromagnetic survey is being flown over the target and is scheduled for completion by November 6.
“The UltraFine+ soil program has delivered a valuable new layer of geochemical intelligence across Mindoolah, revealing clear spatial alignments between elevated gold, structural corridors, magnetic features, and key lithological contacts. On the eastern side, the high-grade 231.8 ppb Au result at Golden Gate highlights an exciting target immediately adjacent to historical workings and mapped quartz veining.”
King River’s confidence for the larger drill-out was bolstered by a phase-one campaign that returned a 79 per cent hit rate and several notable intersections, including 1 metre at 13.59 g/t gold at the Bertram’s prospect and 3 metres at 4.7 g/t gold at Le Soleil.
The Mindoolah project became King River’s flagship after the company exercised its option to acquire the ground in March, a shift that followed the appointment of Graham Gadsby as managing director in October last year. Gadsby previously worked at Spartan Resources and was involved in discoveries at the Never Never and Pepper deposits near Sandstone.
To fund the exploration push, King River has been selling down part of its holding in ASX-listed Tivan Limited, an investment that was valued at more than $12.6 million at the end of September and has provided cash to support the Mindoolah programs without an immediate capital raise.
With recent drilling under way and assays pending from multiple programs, King River is progressing field work across several drill-ready targets defined by the new soil geochemistry and existing historical data.
