Hurricane Project Delivers Outstanding Gold-Antimony Discoveries Across 20+ High-Grade Prospects
Rokeby Resources Limited (ASX: RKB) has delivered exceptional exploration results from its 100%-owned Hurricane Project in northern Queensland. Rock chip sampling has confirmed multiple new high-grade gold and antimony targets across what appears to be a district-scale mineralised system. The latest sampling program has identified 10 new prospects and returned peak assays of 25.78 g/t Au and 22.08% Sb.
The comprehensive field program has now confirmed high-grade gold mineralisation across at least 20 prospects at Hurricane. The newly identified targets include Nor'easter, Twister, Howling, Gale, Squall, Blizzard, Thermal, Scud, Willy-willy, and Buster. This expansive discovery demonstrates the widespread distribution of mineralised veins throughout the project area.
Furthermore, these results reinforce the scale and continuity of the gold-antimony system across this significant exploration project.
"These results build on previous work and demonstrate the widespread distribution of mineralised veins throughout the project area, highlighting the scale and continuity of the orogenic gold–antimony system at Hurricane." – Management Commentary
High-Grade Gold Results Define Multiple Target Areas
The latest sampling program has delivered remarkable gold assay results across multiple prospects. Several samples have returned multi-gram gold values that underscore the high-grade potential of the Hurricane system.
In addition, the consistency of results across different geological zones suggests robust structural controls on mineralisation.
Gold-Dominant Highlights
| Prospect | Sample ID | Gold Grade (g/t) | Significance |
|---|---|---|---|
| Nor'easter | IRX00180 | 25.78 | Highest gold grade recorded |
| Twister | IRX00300 | 20.11 | New high-grade discovery |
| Hurricane | IRX00385 | 9.61 | Core prospect validation |
| Nor'easter | IRX00179 | 9.57 | Consistent high-grade zone |
| Twister | IRX00293 | 8.23 | Multiple high-grade intercepts |
| Nor'easter | IRX00182 | 8.05 | Prospect expansion confirmed |
| Twister | IRX00287 | 7.74 | District-scale potential |
The results confirm that high-grade gold mineralisation extends across multiple structural corridors. The Nor'easter and Twister prospects have emerged as particularly compelling targets for follow-up drilling. Moreover, the consistency of high-grade results across different prospects suggests robust geological controls on mineralisation.
Antimony-Rich Zones Offer Dual-Commodity Potential
Equally impressive are the antimony-rich intercepts, particularly from the Howling and Gale prospects. These areas have returned exceptional antimony grades accompanied by significant gold values.
However, the combination of both commodities offers enhanced project economics and market diversification benefits.
Gold-Antimony Highlights
| Prospect | Sample ID | Antimony (%) | Gold (g/t) | Combined Value |
|---|---|---|---|---|
| Howling | IRX00117 | 22.08 | 1.77 | Exceptional dual grades |
| Howling | IRX00114 | 20.69 | 0.78 | High antimony potential |
| Gale | IRX00116 | 18.26 | 1.64 | Strong Sb-Au association |
| Howling | IRX00235 | 15.90 | 0.74 | Consistent mineralisation |
| Gale | IRX00124 | 15.28 | 0.66 | Multiple high-grade zones |
| Gale | IRX00119 | 13.35 | 1.34 | Robust grade continuity |
These results define a strong Sb-As-Au-Ag geochemical association typical of sediment-hosted orogenic gold systems. This signature is comparable to world-class deposits like Macraes in New Zealand and Fosterville in Victoria.
For instance, the antimony-gold correlation demonstrates the system's potential for dual-commodity extraction scenarios.
Understanding Orogenic Gold Systems: The Hurricane Advantage
Orogenic gold deposits represent one of the most significant sources of global gold production worldwide. These systems are characterised by gold-bearing quartz veins formed during mountain-building processes. They typically develop along major fault zones where hot, metal-rich fluids migrate upward from deep crustal sources.
Furthermore, these geological environments often produce some of the world's highest-grade gold deposits.
Why Orogenic Systems Attract Investment Interest
Key characteristics that make orogenic systems attractive to investors:
- High-grade potential: Often contain multiple ounces per tonne gold grades
- Structural controls: Well-defined geological controls aid in exploration targeting
- District-scale systems: Can host multiple deposits across large areas
- Long production life: Many operate profitably for decades
The Hurricane Project displays all the hallmarks of a significant orogenic gold system. In addition, the project benefits from antimony co-credits that could enhance project economics. Antimony prices have strengthened significantly in recent years due to supply constraints and increasing demand from flame retardants and battery applications.

- Orogenic: Relating to mountain-building geological processes
- Stibnite: The primary antimony mineral (Sb₂S₃)
- Rheological contrast: Differences in rock strength that focus fluid flow
Strategic Structural Framework Guides Future Drilling
Comprehensive structural mapping has revealed critical geological controls on mineralisation. The Hurricane and Retina Faults form a major sinistral (left-lateral) fault pair that acts as the primary control on fluid flow and mineralisation. This geological architecture is highly favourable for gold deposition.
Moreover, dilation along northeast-trending fold axes promotes the emplacement of multiple mineralised vein sets.
Key Structural Discoveries Include:
- District-scale fault network: Major faults with secondary splays and linking structures
- Favourable vein geometries: Sheeted, laminated shear veins and extensional quartz veins
- Lithological controls: Mineralisation concentrated at sandstone-mudstone contacts
- Dilational zones: Areas of structural opening that focus mineralising fluids
The structural review has identified the Gale-Howling-Bouncer area as an antimony-rich structural domain. Meanwhile, the central zone encompassing Hurricane, Tornado, and Cyclone prospects hosts extensive gold occurrences within a dilational hinge zone. This geometry is highly favourable for fluid focusing and vein repetition.
What Makes Hurricane's Geology So Promising?
The structural controls at Hurricane demonstrate textbook examples of favourable geological environments for gold deposition. The intersection of major fault systems creates multiple zones of structural dilation. These areas act as natural conduits for mineralising fluids, concentrating gold and antimony in economic grades.
However, the true significance lies in the district-scale nature of the system, suggesting multiple deposit potential across the project area.
Accelerated Phase 2 Drilling Program Takes Shape
With the completion of systematic target analysis, Rokeby is finalising plans for a Phase 2 reverse circulation (RC) drilling program. This program will build directly on these exceptional surface results. The company's systematic approach demonstrates professional geological methodology.
In addition, this structured approach maximises the potential for discovery success.
Pre-drilling Analysis Components:
