Exploration Uncertainty Looms Despite Gold Discoveries at Kiabye
Red Mountain Mining has confirmed promising gold mineralisation at its Kiabye Gold Project in Western Australia, with initial drilling returning a best intercept of 2.92 g/t Au over 1m. The company also discovered new alluvial gold nuggets at Prospectors Patch, expanding its exploration potential.
- Initial RC drilling confirms auriferous quartz veining at Kiabye South
- Best assay result – 2.92 g/t gold over 1 metre
- Discovery of six new alluvial gold nuggets at Prospectors Patch
- Magnetic anomalies guide further drilling and sampling plans
- Next steps include expanded drilling and source tracing for alluvial gold
Exploration Breakthrough at Kiabye
Red Mountain Mining Limited (ASX, RMX) has reported encouraging early-stage exploration results from its 100%-owned Kiabye Gold Project, located in the Murchison Province of Western Australia. A recent slimline reverse circulation (RC) drilling program comprising nine holes and nearly 1,000 metres of drilling has confirmed the presence of structurally controlled auriferous quartz veining, particularly at the Kiabye South prospect.
The standout result from this drilling was an intercept of 2.92 grams per tonne (g/t) gold over 1 metre, a significant indicator of potential economic mineralisation. This intercept, alongside other anomalous gold values, supports the interpretation of a north-south trending magnetic linear feature as a key structural control for gold mineralisation.
New Gold Nuggets at Prospectors Patch
Adding to the positive momentum, Red Mountain’s geological team discovered six alluvial gold nuggets at Prospectors Patch, a new area within the project’s southeast licence. The largest nugget weighs 10 grams, with a total combined weight of 13.1 grams recovered. These nuggets were found in a localized area less than 200 by 200 metres and are visually identified as native gold, though assay confirmation of purity is pending.
The presence of ferruginous and gossanous quartz breccias near a major thrust fault suggests potential primary sources for the alluvial gold, which the company plans to systematically sample. This discovery broadens the scope of exploration beyond the quartz reef targets and highlights the geological complexity of the Kiabye project area.
Geophysical Insights and Drilling Details
At Kiabye North, drilling intersected magnetite-bearing quartz veins associated with magnetic anomalies, although only trace gold was detected. This contrasts with the more promising results at Kiabye South, where drilling targeted soil anomalies and historical shallow drilling results. Three of seven holes at Kiabye South returned anomalous gold grades, reinforcing the potential of the magnetic lineament as a mineralised corridor.
The drilling program employed slimline RC techniques with careful sampling protocols, including quality control measures such as duplicates, blanks, and standards. Assays were conducted using lead fire assay methods at Intertek Perth Lab, ensuring reliable gold quantification.
Next Steps and Corporate Outlook
Red Mountain Mining plans to review the current drilling results in detail and compile further drill targets along the gold-bearing magnetic lineament, prioritising areas highlighted by the recent drilling success. Additionally, sampling of quartz veins and breccias at Prospectors Patch will aim to trace the primary sources of the alluvial gold nuggets.
On the corporate front, the company’s Annual General Meeting is scheduled for 6 November 2025, with director nominations closing on 18 September. Investors will be watching closely for updates on exploration progress and strategic developments.
Bottom Line?
Red Mountain Mining’s latest results at Kiabye mark a promising step forward, but the true scale and economic viability of the gold mineralisation remain to be proven with further drilling and sampling.
Questions in the middle?
- Will follow-up drilling at Kiabye South confirm a continuous gold lode suitable for resource definition?
- Can the primary source of the alluvial gold nuggets at Prospectors Patch be identified and economically developed?
- How will the company prioritise exploration targets given the contrasting results between Kiabye North and South?
