King River Resources Moves to Acquire Historic Mindoolah Gold Project in WA's Murchison Region
King River Resources has taken a significant step by securing an exclusive option to acquire the high-grade Mindoolah gold project, located approximately 70 kilometres northwest of Cue in Western Australia's renowned Murchison region. This strategic move targets a historic mining area with a rich legacy of gold production dating back to the early 1900s.
Historic High-Grade Gold Production and Untapped Potential
Historical mining operations at Mindoolah yielded an impressive average grade of 19.02 grams per tonne (g/t) gold, producing over 5,700 ounces. However, early miners were constrained by technological limitations, such as water access and depth, with workings typically stopping around the 20-metre level. This means they only scratched the surface, leaving substantial potential for modern exploration techniques to uncover deeper mineralisation.
The tenure package spans about 100 square kilometres of highly prospective greenstone terrain, much of which lies under shallow cover and remains largely underexplored. Management at King River Resources believes that the true source of the historic high-grade reefs has never been adequately tested using contemporary methods like modern geophysics, ultra-sensitive soil geochemistry, or systematic drilling, indicating significant blue-sky potential.
Compelling Drill Targets and Geological Setting
Numerous walk-up drill targets are evident, supported by abundant gold occurrences in rock chips and outcropping quartz veins along strike from old workings and pits. For instance, historical drilling in the 1980s at the Excelsior prospect intercepted 4 metres grading 9.3 g/t gold from 33 metres and another 4 metres grading 8.85 g/t from 32 metres, suggesting that unmined gold lodes extend to depth beneath old workings.
Additional high-grade results include trench sampling at the Cundy prospect averaging 6.08 g/t gold, and quartz vein sampling at Excelsior Southeast, 120 metres from the main pit, assaying 9.98 g/t gold. Nearby prospects like Bertrams and Le Soliel also show numerous rock chips exceeding 15 g/t gold, reinforcing the area's mineral richness.
Geologically, Mindoolah is situated in the Youanmi Terrane, featuring a variety of Archaean rock types, including mafic volcanic rocks, banded iron formation, and amphibolite, intruded by a large monzogranite body. Gold mineralisation occurs as quartz reefs and stockworks, ranging from one to five metres in width within and around this intrusion. This setting has historically delivered multiple high-grade deposits across the Murchison region, such as Big Bell, Day Dawn, and Blue Bird.
Strategic Acquisition and Future Outlook
Under the agreement, King River Resources has secured an exclusive option for $225,000, with the right to purchase the project outright for $600,000 in cash. The option can be exercised at any time before its expiry on 30 June 2026. This acquisition aligns with the company's mandate to focus on high-grade gold opportunities in proven mineralised corridors, leveraging expertise to create value rapidly.
King River Resources managing director Graham Gadsby emphasised the project's potential, stating, "Our mandate is clear: we are zeroing in on high-grade gold opportunities within proven mineralised corridors where we can deploy our expertise to create value rapidly. The project's historical production grade of 19.02 g/t Au is a testament to the exceptional quality of this mineralising system. The fact that high-grade intercepts such as 4m @ 9.30 g/t Au remain unmined at shallow depths represents a compelling opportunity that has been overlooked for decades."
Mindoolah represents a classic revival story in the mining sector. If modern exploration tools can unlock what early miners could not reach, King River Resources may have revitalised a forgotten goldfield, offering it a very modern second life with promising prospects for future development and resource expansion.
