Tambourah Metals Expands Gold Anomaly at Beatty Park South, Eyes RC Drilling
Tambourah Metals has identified a significant gold anomaly at its Beatty Park South project through ultrafine soil sampling, prompting plans for follow-up RC drilling to test high-grade mineralisation.
- Contiguous gold anomaly defined over 150m by 100m area
- Ultrafine soil sampling reveals strong gold anomaly west of aircore drilling
- Anomaly remains open to north and south, suggesting further potential
- High-grade gold intersections from previous aircore drilling underpin follow-up plans
- UAV-borne sub-audio magnetic survey planned to refine drill targeting
Exploration Update at Beatty Park South
Tambourah Metals Ltd (ASX – TMB) has released encouraging soil sampling results from its 100%-owned Beatty Park South gold project, located in Western Australia's Bryah Basin. The company’s recent ultrafine fraction (UFF) soil sampling has delineated a contiguous gold anomaly spanning approximately 150 metres by 100 metres, extending westward beyond the current aircore drilling footprint.
This anomaly is particularly notable given the high-grade gold mineralisation previously intersected in aircore drilling, including standout results such as 6 metres at 25.8 grams per tonne gold from 30 metres and 10 metres at 38.9 grams per tonne gold from 22 metres. The new soil sampling results reinforce the prospectivity of the area and highlight zones that were not effectively tested by historic drilling, partly due to shallow water tables that limited penetration.
Innovative Sampling and Historical Context
The ultrafine soil sampling technique employed by Tambourah analyses a -2 micron fraction of soil, enabling detection of subtle gold anomalies that traditional methods might miss. This approach has proven effective in identifying mineralisation related to underlying bedrock structures, although no direct correlation with other elements has been established yet.
Beatty Park South sits within the Narracoota Formation, a geological setting known for hosting gold mineralisation associated with volcanic and ultramafic rocks. Historical exploration dating back to the 1980s included RAB, RC, and diamond drilling, but limitations in collar location accuracy and shallow water tables have left significant gaps in the understanding of the deposit’s extent.
Next Steps and Strategic Outlook
Tambourah is advancing plans for reverse circulation (RC) drilling to follow up on the high-grade gold zones identified in aircore drilling and soil sampling. Additionally, the company is preparing to complete a UAV-borne sub-audio magnetic (SAM) geophysical survey over a 2km by 1km area encompassing the anomaly and its potential strike extensions. This high-resolution survey will help map conductive structures such as faults and shears that may control mineralisation, providing critical targeting data for upcoming drilling campaigns.
Meanwhile, results from a recent 3,300-metre aircore drilling program are pending, which could further refine the exploration model. Tambourah’s methodical approach, combining innovative geochemical techniques with geophysical surveys and targeted drilling, positions the company well to unlock the potential of Beatty Park South within the prolific Bryah Basin.
Bottom Line?
Tambourah Metals’ expanding gold anomaly and planned drilling set the stage for a pivotal phase in its Beatty Park South exploration story.
Questions in the middle?
- Will upcoming aircore drilling results confirm the continuity of high-grade mineralisation?
- How will the SAM geophysical survey influence drill targeting and resource potential?
- What are the implications of historic drilling limitations on current exploration models?
