Inca Minerals has significantly expanded high-grade gold-antimony zones at its Hurricane Project in Queensland, with rock chip assays revealing new mineralised extensions and multiple vein structures. Preparations for a maiden drilling program are underway, setting the stage for a pivotal exploration phase.
- High-grade gold-antimony mineralisation extended at Bouncer South by 90m strike and 70m width
- Exceptional rock chip assays include 69.48 g/t gold and 6.53% antimony
- Typhoon Prospect mineralisation extended 100m northwest with 40.02 g/t gold sample
- New stacked vein potential identified between Typhoon and Hurricane prospects
- Maiden reverse circulation drilling program scheduled to commence imminently
Expanding the Footprint of a Promising Gold-Antimony System
Inca Minerals Limited (ASX – ICG) has announced a significant expansion of high-grade gold and antimony mineralisation at its 100%-owned Hurricane Project, located in the historically productive Hodgkinson Province of north Queensland. Recent rock chip sampling across multiple prospects has extended known mineralised zones and revealed new structural complexities, underscoring the project's potential as a multi-phase orogenic gold-antimony system.
The standout results come from the Bouncer South zone, where assays confirm a substantial extension of mineralisation by 90 metres along strike and over 70 metres in surface width. Here, rock chips returned impressive grades, including 6.53% antimony paired with 6.44 grams per tonne (g/t) gold, highlighting the coexistence of gold-dominant stockworks and high-grade antimony lodes. This dual mineralisation signature aligns with models of multiple mineralising events, suggesting a rich and complex geological history.
Typhoon and Hurricane Prospects Reveal New Opportunities
At the Typhoon Prospect, sampling has extended the known mineralised footprint 100 metres northwest, with a remarkable 40.02 g/t gold assay from quartz veining. Between Typhoon and Hurricane, assays of 12.29 g/t and 3.60 g/t gold indicate the presence of stacked quartz vein sets, pointing to multiple parallel mineralised structures within this corridor. Additionally, a spectacular 69.48 g/t gold result from Hurricane South, located 70 metres east of previously known mineralisation, suggests the potential for additional parallel veins within the Hurricane corridor.
These findings collectively paint a picture of a growing and geologically intricate system, with both high-grade shoots and broader mineralised zones. The presence of antimony alongside gold further enhances the project's appeal, given antimony's critical role in various industrial applications.
Drilling Preparations Signal a New Phase
Inca Minerals is advancing swiftly towards its maiden reverse circulation (RC) drilling program, with site preparations well underway. Bulldozers are currently constructing drill pads and access tracks, and the RC rig is poised to mobilise immediately upon completion of these works. This drilling campaign, expected to commence in July 2025, represents a crucial step in testing the subsurface extent of the mineralisation and refining the understanding of the system's architecture.
Strategic Location and Geological Context
The Hurricane Project sits within the Hodgkinson Province, a structurally complex terrane known for its historic gold production and orogenic gold systems. The region's metamorphosed Siluro-Devonian sediments have undergone multiple deformation events, creating favourable conditions for gold mineralisation along reactivated fault zones. The project's geochemical signature, featuring gold, antimony, arsenic, and silver, is consistent with globally significant deposits such as Macraes in New Zealand and Fosterville in Victoria.
With large areas still underexplored and a well-established mineralising environment, Inca Minerals' Hurricane Project is well positioned to deliver new discoveries that could reshape the district's mining landscape.
Bottom Line?
As drilling looms, Inca Minerals stands on the cusp of unlocking the true scale of Hurricane’s high-grade gold-antimony system.
Questions in the middle?
- Will the upcoming drilling confirm the continuity and depth of the high-grade zones identified at surface?
- How might the multi-phase mineralisation model influence resource estimation and future development plans?
- What are the potential implications of the antimony content for project economics and market positioning?
