Iceni Gold Commences Deep Diamond Drilling at High-Priority Welcome Creek Target
Iceni Gold Limited (ASX: ICL) has commenced a major 1,500-metre deep diamond drilling program at its Welcome Creek copper-gold project in Western Australia's Paterson Orogen. The company is targeting a large-scale geophysical anomaly that has remained unexplained for over 30 years, with characteristics similar to Iron Oxide-Copper-Gold (IOCG) deposits.
Furthermore, the deep diamond drilling by Iceni Gold Ltd represents a significant milestone in testing this compelling target. The single diamond hole (WCD001) aims to intersect a modelled source at 965 metres depth, with drilling expected to be completed by early December 2024 and assay results anticipated in January 2025. The programme is co-funded by up to $150,000 from the Western Australian Government's Exploration Incentive Scheme.
Major Geophysical Target Finally Gets Its Test
Welcome Creek represents one of the Paterson Orogen's most intriguing exploration puzzles. The project covers a compelling 4-5 kilometre coincident gravity-magnetic "bullseye" anomaly that was first identified in 1990 but never properly tested until now.
In 1993, Normandy Poseidon drilled a single 701-metre diamond hole (LDDH1) to investigate the anomaly but only intersected bedded sedimentary cover without reaching the basement source. The hole was originally planned to 450 metres but was extended to 701 metres in an unsuccessful attempt to reach the anomaly's source.
Key Target Characteristics:
- 4-5 kilometre strike length along northwest-southeast orientation
- 3 kilometre width at the source body
- Modelled source depth of 800 metres from surface
- Located 260 kilometres east of Newman and 140 kilometres south of Telfer
- Situated within the highly prospective Paterson Orogen
Managing Director Commentary
"This deep drilling programme presents a rare opportunity to test a significant anomaly that has intrigued explorers in the Paterson for decades. This is a compelling target and major opportunity for the Company that could potentially deliver the early stages of a new large IOCG system under cover in Western Australia," said Wade Johnson, Managing Director.
Understanding IOCG Deposits: Why This Matters
Iron Oxide-Copper-Gold (IOCG) deposits represent some of the world's most valuable mineral systems, characterised by their large size and high-grade copper-gold mineralisation. These deposits form deep in the Earth's crust where iron-rich fluids interact with favourable host rocks.
What makes IOCG deposits attractive to investors:
IOCG deposits offer several compelling characteristics that make them highly sought after in the mining industry. These systems typically contain large tonnage potential, often hosting hundreds of millions of tonnes of mineralised material. The presence of both copper and gold in the same deposit provides diversified revenue streams and reduces commodity risk.
Long mine lives represent another key advantage, as IOCG deposits can support decades of production due to their substantial size. This translates into strong economics with high margins resulting from the valuable metal content and extended operational periods.
Famous IOCG deposits include Olympic Dam in South Australia, which ranks as the world's fourth-largest copper deposit, and Oak Dam East. According to specialist consultant Newexco's comparative analysis, Oak Dam East shares similar geophysical characteristics to Welcome Creek, providing geological precedent for the target's potential.
The economic significance of IOCG systems extends beyond individual projects, as they often define entire mining districts and support substantial infrastructure development. Consequently, their discovery can transform regional economies and provide decades of employment and economic activity.
Advanced Geophysical Modelling Points to IOCG Potential
Iceni engaged renowned geophysicists Newexco Exploration to reprocess and model all historical geophysical data from Welcome Creek. This comprehensive review has significantly enhanced understanding of the target.
Newexco's Key Findings:
| Parameter | Original Estimate (1993) | Updated Model (2024) |
|---|---|---|
| Source Depth | ~1,700-1,900m | 800m (top of source) |
| Target Depth | Not reached at 701m | 965m beneath drill site |
| Anomaly Type | Unexplained | IOCG-style signature |
| Comparable Deposits | Unknown | Oak Dam East similarity |
The geophysical review confirmed that the magnetic and gravity anomalies cannot be explained by the overlying sedimentary sequence intersected in the original hole. Instead, they indicate a mineralised basement system at depth that shares characteristics with known IOCG deposits.
Newexco's comparative analysis identified several IOCG systems from the Gawler Craton that display similar coincident magnetic and gravity signatures. For instance, BHP's Oak Dam East shows the strongest similarity to the Welcome Creek target.
The updated modelling represents a significant advancement from the original 1993 interpretations. The revision places the target source at a much shallower depth than previously estimated, making it technically and economically feasible to test with current drilling technology. This depth revision fundamentally changes the exploration approach and significantly improves the probability of successfully intersecting the anomaly source.
Strategic Drilling Programme Designed for Success
Iceni has engaged McKay Drilling, a specialist contractor with proven deep diamond drilling capability across the Paterson region. The programme incorporates several strategic elements to maximise success potential.
Drilling Programme Details:
| Phase | Depth Range | Method | Core Size |
|---|---|---|---|
| Initial | 0-200m | Mud rotary | N/A |
| Primary | 200-700m | Diamond drilling | HQ core |
| Target Zone | 700-1,500m | Diamond drilling | NQ core |
Value-Added Programme Features
The drilling approach includes daughter hole capability, with WCD001 established to industry standard allowing follow-up holes if mineralisation is discovered. Drillhole Electromagnetic (DHEM) surveying will identify conductive bodies along or near the hole path, potentially indicating sulphide mineralisation.
Comprehensive assaying using four-acid digest with ICP-OES/ICP-MS will test for approximately 48 elements, providing detailed geochemical characterisation. Petrographic analysis through thin section analysis has been reserved if mineralisation is intercepted, allowing for detailed mineralogical understanding.
The company attempted to re-enter the original LDDH1 hole to extend it past 701 metres but abandoned this approach at 160 metres depth. However, this led to the current new vertical hole strategy. This decision ensures optimal hole conditions and eliminates potential complications from the decades-old original drilling.
Geological Setting Supports Multiple Deposit Types
Welcome Creek sits within the Paterson Orogen, a highly prospective Proterozoic province that hosts numerous large gold and copper deposits. The local geology combines several factors favourable for significant mineralisation.
Favourable Geological Elements
The project benefits from reactive host rocks including carbonate and evaporite-rich packages of the Tarcunyah Sequence. These chemically reactive formations provide ideal environments for mineralising fluid interaction and metal precipitation.
Major structures in proximity to the northwest-trending Vines-McKay fault system provide the necessary structural controls for mineralising fluid flow. This represents proven mineralisation control, as the same structural system controls mineralisation at the Nifty Copper Deposit. Therefore, this demonstrates the regional fertility of these structural corridors.
The basin-margin setting creates an optimal environment for multiple mineral system types. This geological position allows for the interaction of different fluid systems and provides the necessary chemical and physical conditions for large-scale mineralisation processes.
Deposit Type Potential
The combination of chemically reactive Waters and Karara Formation host rocks with large-scale structural controls creates potential for several deposit types. These include IOCG/intrusion-related copper-gold systems, sediment-hosted copper deposits, and basin-margin base metal systems similar to Admiral Bay.
This geological diversity provides multiple pathways to discovery success, reducing exploration risk whilst maintaining significant upside potential. The presence of proven deposits in similar geological settings throughout the Paterson Orogen validates the exploration concept and provides geological precedent for significant mineralisation.
