Red Mountain Gold Project Drilling Opens New Depths but Challenges Remain
Zenith Minerals has confirmed the lateral and depth expansion of its Red Mountain gold system in Queensland, with strong results from recent reverse circulation drilling and the commencement of diamond drilling to target high-grade zones.
- Final assays from October 2025 RC drilling confirm expanding gold mineralisation
- Diamond drilling underway to follow up high-grade breccia-hosted gold intercepts
- Notable intercepts include 122m at 1.28 g/t Au and 7m at 0.99 g/t Au
- Gold system remains open at depth and along a northwest-trending corridor
- Project benefits from strong metallurgy and proximity to established infrastructure
Expanding Gold Footprint at Red Mountain
Zenith Minerals Limited has released the final assay results from its October 2025 reverse circulation (RC) drilling campaign at the Red Mountain Gold Project in Queensland. The data confirms a significant expansion of the intrusion-related gold (IRG) system, both laterally and at depth, reinforcing Red Mountain’s status as a promising emerging gold deposit.
The recent RC holes, particularly ZRMRC070 through ZRMRC073, reveal continuous gold mineralisation along a northwest-trending corridor that remains open for further extension. Highlights include a broad 93-metre intercept averaging 0.43 grams per tonne (g/t) gold from 314 metres, and a 34-metre intercept averaging 0.39 g/t gold from 176 metres, with higher-grade zones embedded within these intervals.
Transition to Diamond Drilling
Building on these encouraging results, Zenith has commenced diamond drilling by re-entering hole ZRMRC073 from 210 metres to test the breccia-hosted gold system at greater depths. This follow-up targets the highest-grade breccia intercept to date, which returned 7 metres at 0.99 g/t gold from 177 metres. The diamond tail aims to explore the mineralisation adjacent to and below this zone, particularly near the standout 122 metres at 1.28 g/t gold intercept in hole ZRMRC068.
Managing Director Andrew Smith emphasised the strategic importance of this phase, noting that the diamond drilling will provide critical insights into the system’s vertical continuity and potential feeder structures. Early indications suggest the mineralised breccia pipe remains open and may host a large-scale IRG system comparable to other significant Queensland gold deposits.
Geological and Metallurgical Context
The Red Mountain project is situated within a geologically fertile region known for intrusion-related gold systems, sharing characteristics with established mines such as Mt Wright and Mt Rawdon. The mineralisation is hosted within a breccia pipe system overlain by rhyolite sills, with gold grades strengthening where these geological features interact.
Metallurgical testwork has demonstrated that much of the gold is free-milling and amenable to conventional cyanide leaching, with recoveries averaging 83.3% and reaching up to 95.8% in low-arsenic samples. This bodes well for potential future processing and economic viability.
Looking Ahead
With the RC drilling phase complete and diamond drilling underway, Zenith is well positioned to refine its geological model and advance resource definition. The continuity and scale of the mineralised system, combined with favourable metallurgy and infrastructure, underscore Red Mountain’s potential as a cornerstone asset in Zenith’s gold portfolio.
Bottom Line?
As diamond drilling progresses, Red Mountain’s evolving gold system could reshape Zenith’s growth trajectory in Queensland’s gold sector.
Questions in the middle?
- Will diamond drilling confirm a high-grade feeder zone at depth?
- How will the expanding mineralised corridor impact future resource estimates?
- What are the timelines for updated resource and feasibility studies?
