The Murchison province of Western Australia has long been a canvas for mineral exploration, its rugged terrain a backdrop for the search for hidden riches. The company’s latest campaign of soil sampling has already revealed a series of gold‑laden pockets that could redefine the potential of the site.
Unlike the dramatic flash of a drill bit, the story of gold in the Murchison begins in the soil. King River deployed an UltraFine+ sampling campaign, systematically collecting and analysing samples across the eastern and western zones of the project. The data are striking: the highest concentration recorded was 231.8 ppb at the Golden Gate prospect, a figure that dwarfs the normal background of 2 ppb that characterises the region.

At Golden Gate, the 231.8 ppb reading is not just a number; it is a signal that the gold‑bearing mineralisation is concentrated enough to warrant deeper investigation. In a landscape where background levels hover around 2 ppb, a spike of this magnitude suggests a structural corridor that could host economically viable ore bodies.
These ratios underscore the consistency of the enrichment across the property and reinforce the hypothesis that the gold is structurally controlled.
The Le Soleil‑Demagnetised target corridor, another focus of the sampling effort, delivered a peak of 69.9 ppb. While lower than Golden Gate, this figure still represents a significant enrichment above background and aligns with the structural trends mapped by the company’s geological team.

The mean gold concentration in the eastern zone sits at 21 ppb, ten times the background, while the western zone averages 27 ppb, five times the background. These ratios underscore the consistency of the enrichment across the property and reinforce the hypothesis that the gold is structurally controlled.
The divergence between the eastern and western zones is subtle but meaningful. The eastern zone’s 21 ppb mean reflects a broader, more diffuse mineralisation, whereas the western zone’s 27 ppb points to a tighter, possibly more concentrated system. Together, they paint a picture of a complex mineralised network that spans the entire project.
King River Resources has hit shallow, high-grade gold at its Mindoolah project in WA’s Murchison. Maiden drilling returned a 79 per cent hit rate, with intercepts up to 1m at 13.59g/t and 1m at 10.70g/t gold. #BULLSNBEARSWA https://t.co/uMGm6w35Ow https://t.co/YP2IEbjXms
Armed with these promising surface signals, King River has outlined an ambitious 11,000‑metre phase‑two drilling program. The plan is to drill through the structural corridors highlighted by the soil data, testing the continuity of the gold‑bearing zones and seeking to translate surface enrichment into deep‑strike ore.
The Murchison project is not a blank slate. That result, coupled with the new soil data, creates a compelling narrative that the property hosts both shallow and deeper gold systems.
“All Excelsior samples are now in the laboratory for assay, and the rig has shifted to begin drilling at the Demagnetised target,” said Graham Gadsby, head of exploration. The move signals confidence that the Demagnetised corridor, buoyed by the 69.9 ppb peak, will yield further insight.
As the company progresses through its 11,000‑metre schedule, each new assay will either confirm the structural model or refine it, but the early data already suggest a property that could become a cornerstone of Western Australia’s gold sector.
With a clear path from surface enrichment to deep drilling, King River Resources is poised to transform the Murchison project from a promising prospect into a potential flagship operation. In a mining world that prizes both risk and reward, the Murchison project stands as a testament to the power of systematic, data‑driven exploration.
