- Zenith has extended the mineralised IRG gold system beyond 700 metres in depth at its Red Mountain project in Queensland.
- Mineralised breccia system remains open at depth and along strike.
- Multiple high-priority target zones are yet to be tested.
Zenith Minerals (ASX:ZNC) has extended the mineralisation at its Red Mountain project by 350 metres, with deep diamond drilling to 758 metres confirming a large-scale, vertically extensive mineralised breccia system extending beyond 700 metres, with broad zones of continuous mineralisation intersected at depth.

The explorer’s MD, Andrew Smith, said the intrusion-related gold (IRG) system at Zenith’s Queensland project remains open at depth and along strike, with multiple high-priority target zones identified.
“Importantly, newly developed 3D geochemical modelling defines clear vectors towards higher-grade, intrusion-proximal zones, providing a well-defined and immediate focus for the next phase of drilling,” he explained.
Mr Smith went on to highlight holes ZRMCD073 and ZRMCD067 for shareholders, especially the fact that they have confirmed the impressive scale and continuity of the Red Mountain IRG system, with spotted diamond tails from the holes representing the deepest drilling completed at Red Mountain.
“Combined with our newly built 3D geochemical model, these results significantly improve our understanding of the rhyolite feeder and sills geometry and are directly guiding us toward the higher-grade core of the system,” he added.
“Red Mountain remains a large-scale, underexplored intrusion-related gold system in a Tier-One province, and we believe the best parts – including potential for higher-grade mineralisation – are still ahead of us.”
Holes ZRMCD073 and ZRMCD067 intersected extensive breccia, brecciated granodiorite and rhyolite, confirming and extending the vertically extensive hydrothermal system by hundreds of metres.
Discrete, flat-lying rhyolite sills were intersected, along with a 60m interval of massive to porphyritic rhyolite in ZRMCD067, representing a sub-vertical feeder zone.
“ZRMCD067 terminated within the breccia pipe, demonstrating a vertically extensive hydrothermal system that remains open at depth and along both northwestern and southeastern directions,” Mr Smith said today.
Zenith is also conducting ongoing multi-element geochemical analysis of the diamond tail samples to refine the geochemical model and improve vectoring toward higher-grade zones. On that, Mr Smith said, “These results, combined with drilling data, will support the refinement of the geological model for rhyolite feeder zones and sills, and guide the design of future drill programs.”
ZNC is up +5.97%, to 7.1¢ today. Mkt cap $40.20M.
