Tambourah Metals has identified two promising gold targets at its Beatty Park South prospect through advanced geophysical and soil sampling techniques, setting the stage for imminent drilling campaigns.
- Integration of SAM geophysical data with ultrafine soil sampling defines two new gold targets
- Target 1 shows gold-in-soil anomalies up to 70ppb Au, extending west of existing drilling
- Target 2 located 1.1 km south with up to 21ppb Au and no prior drilling coverage
- Planned aircore and RC drilling totaling approximately 5,500m approved and pending heritage clearance
- Structural breaks and hydrothermal alteration zones linked to gold mineralisation
Advanced Exploration Techniques Reveal New Targets
Tambourah Metals Limited (ASX, TMB) has expanded its gold exploration footprint at the Beatty Park South prospect, part of its extensive Bryah Gold project in Western Australia. By integrating high-resolution sub-audio magnetic (SAM) geophysical data with detailed ultrafine soil sampling, the company has delineated two high-priority gold targets that promise to extend known mineralisation zones.
The SAM survey, conducted over 55 line kilometres, provided detailed imagery of the subsurface structural framework, highlighting key north-south and northwest-southeast structural breaks. These structural features coincide with magnetic and conductivity lows indicative of hydrothermal alteration zones, which are often associated with gold mineralisation.
Target 1, A Strong Extension West of Current Drilling
Target 1 (T1) lies approximately 200 metres west of Tambourah’s existing drilling and is characterised by a contiguous gold-in-soil anomaly with values reaching up to 70 parts per billion (ppb) gold. This target aligns with a structural break and is supported by previous aircore drilling results that reported significant supergene gold mineralisation, including a standout intercept of 1 metre at 22.9 grams per tonne gold from 4 metres depth.
Historical auger soil sampling also corroborates the presence of a gold anomaly coincident with T1, reinforcing its potential as a priority drill target. The integration of geophysical and geochemical data here has effectively expanded the known mineralised footprint, offering a compelling case for further exploration.
Target 2, Untested Ground to the South
Located about 1.1 kilometres south of current drilling, Target 2 (T2) presents a broader but lower tenor gold-in-soil anomaly, peaking at 21ppb gold. This target is associated with a conductivity low and intersected by north-south structures, yet it remains untested by previous drilling efforts. The presence of transported cover in this area, suggested by reduced concentrations of lithostratigraphic indicator elements, adds a layer of complexity to exploration but also highlights the prospectivity of this underexplored zone.
Next Steps, Drilling Programs Ready to Advance
Tambourah Metals has secured Program of Work approvals for both aircore and reverse circulation (RC) drilling programs designed to test these newly defined targets. The planned drilling will include up to 50 aircore holes (~3,000 metres) at Target 1 and approximately 25 aircore holes (~1,500 metres) at Target 2. Additionally, around five RC holes (~1,000 metres) will target depth extensions of high-grade mineralisation identified in earlier drilling.
Heritage clearance applications are currently underway, with responses expected within six weeks. The company’s methodical approach, combining cutting-edge geophysical imaging with detailed geochemical sampling, positions it well to unlock further value from the Bryah Gold project.
Strategic Significance in Western Australia’s Gold Landscape
Beatty Park South sits within the Narracoota Formation, a geological setting known for hosting Proterozoic shear-hosted quartz vein gold deposits. Tambourah’s findings of structural breaks and hydrothermal alteration zones align with this model, suggesting that the new targets could represent extensions of economically significant mineralisation.
As Tambourah Metals advances its exploration, the market will be watching closely for drill results that could validate these targets and potentially lead to resource upgrades. The company’s strategic positioning in the Bryah Basin, combined with its disciplined exploration methodology, underscores its potential to contribute meaningfully to Western Australia’s gold sector.
Bottom Line?
With drilling approvals in hand and compelling new targets defined, Tambourah Metals is poised to deepen its gold discovery at Beatty Park South; next comes the drill bit.
Questions in the middle?
- Will the upcoming drilling confirm the continuity and grade of gold mineralisation at Targets 1 and 2?
- How might heritage clearance timelines impact the planned exploration schedule?
- What implications could these new targets have on Tambourah Metals’ resource estimates and valuation?
