The combined 1150sq.km Mt Fisher-Mt Eureka project is described as one of the most remote and least explored greenstone belts in the Yilgarn Craton.

It is not completely isolated, being trucking distance from Wiluna and Northern Star Resources’ Jundee and Bronzewing facilities, but it hasn’t had the attention needed. 

A low-cost program of geophysical surveys along the main corridor has lit up multiple targets, many of which can be considered walk-up targets based on limited work.

Processing of the six gradient array IP surveys defined multiple targets along strike from known gold mineralised trends that indicate potential sulphide-bearing structures, similar to those associated with the existing 187,000 ounce resources across four deposits.

Key prospects include the 75,000oz Damsel deposit where past drilling returned 18m at 6.99 grams per tonne from 69m, including 10m at 10.27gpt – true width unknown; and east of the Wagtail deposit where past drilling returned 9m at 34.34gpt from 67m, including 4m at 74.25gpt – true width unknown.

The anomalies take strike lengths up to 600m. Some that are undrilled have positive rock chip samples.

Rox sees the area that it has largely held since listing as a district-scale exploration opportunity for gold and nickel. 

It owns 100% of the gold rights at Mt Fisher and can earn up to 75% at Mt Eureka, where Cullen Resources has a minority interest. 

Rox spin-off Cannon Resources owns the 134,000t Cannon nickel deposit just outside the tenure.
