Redcastle Resources has identified 16 promising gold targets across the largely underexplored TBone Belt in Western Australia, leveraging historical data and recent fieldwork to expand its exploration pipeline.
- 16 potential walk-up gold targets identified across TBone Belt
- Targets supported by historical geochemistry, old workings, and recent fieldwork
- Only about 50% of TBone Belt historically sampled with limited drilling
- Plans for heritage surveys, geological mapping, and drilling in late 2026
- TBone Belt complements near-term production focus at Queen Alexandra and Redcastle Reef
Expanding the Frontier in the TBone Belt
Redcastle Resources Ltd (ASX, RC1) has announced a significant step forward in its exploration efforts with the identification of 16 potential gold targets within the TBone Belt, a largely underexplored region adjacent to its existing Redcastle Project Area in Western Australia. This discovery comes from a comprehensive review and integration of historical surface geochemical data, old mining workings, and recent field reconnaissance.
The TBone Belt spans approximately 74 kilometres and has historically seen only about half of its area sampled with surface geochemistry, alongside sparse and limited drilling activity. This leaves vast tracts of land untested by modern exploration techniques, presenting a considerable opportunity for new discoveries.
Diverse Targets Backed by Multiple Data Sources
The 16 targets fall into three categories, nine are based on high-grade historical geochemical assay results, five are identified through recent fieldwork and historical workings, and two are supported by all three data sources. Notable targets include Red King, November Find, South Telegraph, Leonidas, Oaklands, and the Margarita Corridor, among others.
Historical drilling, mostly reverse circulation and air core, has been limited and localized, with some promising intercepts such as 4 metres at 0.39 grams per tonne gold at Mt Kersey. However, the scale of drilling is small relative to the size of the geochemical anomalies, indicating significant upside potential along strike and at depth.
Strategic Exploration Plans Ahead
Redcastle plans to advance these targets through a series of heritage surveys, detailed geological mapping, and further geochemical sampling. The company aims to refine and prioritise targets for reverse circulation and diamond drilling programs tentatively scheduled for the third and fourth quarters of 2026.
This exploration push complements Redcastle’s near-term production focus at Queen Alexandra and Redcastle Reef, which already host JORC-compliant mineral resources. The TBone Belt offers a longer-term, scalable exploration platform that could significantly enhance the company’s resource base.
Geological Context and Potential
The TBone Belt lies within the highly prospective Leonora–Laverton Greenstone Belt, a region renowned for orogenic gold deposits. The identified anomalies align with major structural trends and lithological contacts known to host significant gold mineralisation. The presence of transported cover and limited modern exploration means many prospective zones remain concealed, underscoring the potential for new discoveries.
Redcastle’s technical team, led by experienced geologists, is integrating historical data with modern geophysical and geological interpretations to systematically unlock this potential. The company emphasises that while historical data provides a strong foundation, validation through modern sampling and drilling is essential.
Bottom Line?
With a robust pipeline of targets and planned drilling on the horizon, Redcastle’s TBone Belt exploration could reshape its growth trajectory in 2026.
Questions in the middle?
- How will Redcastle validate and prioritise the 16 identified targets with modern exploration methods?
- What impact could successful drilling in the TBone Belt have on Redcastle’s overall resource and production plans?
- How might heritage and environmental considerations affect the timing and scope of upcoming exploration activities?
