Riversgold Expands Drilling Campaign at Kalgoorlie as 2026 Mining Plans Take Shape
Riversgold Limited (ASX: RGL) has commenced its second drilling program of the year at its strategically located Kalgoorlie Gold Project, positioned just 25 kilometres east of Western Australia's renowned Super Pit. The Riversgold Ltd Kalgoorlie drilling campaign Phase 2 program, now underway at the Northern Zone, comprises 30 holes totalling 2,000 metres of drilling and is designed to expand the gold mineralisation footprint ahead of planned mining operations in 2026.
This latest drilling initiative follows an impressive track record of results from the Northern Zone, with standout intersections including 16m at 4.69g/t Au and 18m at 4.14g/t Au. The program targets shallow mineralisation in the top 50-60 metres, positioning the project for cost-effective extraction methods.
Strong Foundation of Historical Results Supports Expansion Strategy
The Northern Zone has delivered consistently encouraging results across multiple drilling campaigns, establishing a solid foundation for the current expansion program. Recent highlights demonstrate the project's potential for substantial shallow gold resources.
Furthermore, the Riversgold Ltd Kalgoorlie drilling campaign has produced several top-tier intersections that showcase the deposit's quality and consistency.
Top-tier intersections include:
- 18m at 4.14g/t Au from 36m depth (NZRC001)
- 16m at 4.69g/t Au from 30m depth (NZAC033)

|---|---|---|---|
| NZRC001 | 18m | 4.14 | 36m |
| NZAC033 | 16m | 4.69 | 30m |
| NZAC127 | 10m | 8.89 | 46m |
| NZAC062 | 5m | 12.27 | 32m |
| NZAC090 | 8m | 4.86 | 34m |
The consistency of high-grade intersections across various depths and drill holes indicates robust mineralisation continuity within the Northern Zone's Tonalite-Trondhjemite Intrusion (TTI) geological setting.
Understanding TTI: The Geological Advantage Behind Northern Zone
Tonalite-Trondhjemite Intrusion (TTI) represents a specific type of igneous rock formation that has proven highly favourable for gold mineralisation. TTI units are characterised by their intermediate to felsic composition and often serve as excellent hosts for precious metal deposits.
Why TTI matters for investors:
- High background gold content creates favourable conditions for economic mineralisation
- Horizontal mineralisation patterns allow for efficient perpendicular drilling techniques
- Absence of groundwater to 60-metre depth reduces drilling costs and complexity
- Structural control through the Canon Shear fault zone concentrates mineralisation
This geological setting positions the Northern Zone for cost-effective extraction methods whilst maximising resource potential within the economically attractive shallow depth range.
The TTI unit's structural characteristics provide several operational advantages. The horizontal nature of gold-bearing units allows drilling programs to intersect mineralisation perpendicularly, optimising hole spacing and reducing total drilling requirements.
Additionally, the absence of groundwater in the upper 60 metres eliminates dewatering costs and simplifies both exploration and potential future mining operations.
Geological Context: TTI Formations
TTI formations develop through specific magmatic processes involving the crystallisation of intermediate to felsic igneous melts. These intrusions typically contain higher concentrations of silica and aluminium compared to basic rocks, creating chemical environments conducive to gold precipitation and concentration.
The Canon Shear fault zone provides additional structural control, creating pathways for hydrothermal fluids that deposit gold within fractures and altered rock zones. This structural setting increases the likelihood of discovering continuous mineralised zones that can support economically viable mining operations.
Strategic Partnership with MEGA Resources Accelerates Development Timeline
The collaboration with MEGA Resources represents a key strategic initiative for Riversgold, providing access to operational expertise and established infrastructure that could accelerate the project's development timeline.
"These programs are designed to enhance the MEGA Resources mining scenario for 2026, and we are pleased to advise that our second shallow drill program is now underway at Northern Zone."
David Lenigas, Executive Chairman
Key development milestones:
- Phase 2 drilling completion: Expected within 2 weeks
- Assay results: First batch from October drilling expected in coming weeks
- Maiden Mineral Resource Estimate: Following completion of drilling programs
