First-Ever Drill Bit Set to Turn at Antares Metals' High-Grade Copper-Gold-Silver Target
Antares Metals Ltd (ASX: AM5) has announced that its Conglomerate Creek prospect within the 100%-owned Mount Isa North Copper Project is advancing rapidly toward a maiden Reverse Circulation (RC) drill program, with commencement targeted for late May 2026. The announcement reveals that the ~1,000m program will mark the first-ever drill test of seven buried geophysical anomalies at the prospect — a target suite that has never previously seen a drill bit, despite carrying exceptional surface grades of up to 21.30% Cu, 1.72 g/t Au, and 506 g/t Ag at surface.
All necessary approvals have been finalised, heritage and land access agreements are secured, and a comprehensive new field campaign is underway to sharpen drill targeting ahead of Antares Metals maiden RC drilling at Conglomerate Creek commencement.
Managing Director Terry Topping commented: "When our team returned rock chip results of twenty-one percent copper from Conglomerate Creek last year, it confirmed what the geophysics had been telling us — there is something significant buried beneath this ground. Since then, we have been doing the systematic work in preparation for drilling: refining our targets, completing the environmental and heritage approvals process, and designing a programme that gives us the best chance of intersecting that system at depth."
"That work is now near complete. We are on track to have the RC rig turning at Conglomerate Creek in late May — the first drill bit ever put into these anomalies — and I am looking forward to sharing results with shareholders in the weeks that follow."

What Is Conglomerate Creek and Why Does It Matter?
The Conglomerate Creek prospect sits within Antares' 1,937 km² Mount Isa North Copper Project tenement package (EPM 26987), located approximately 39 km northeast of Glencore's Mount Isa Operations — one of the world's most significant base metal mining centres.
The prospect has been progressively de-risked over the past 12 months through a disciplined, multi-stage exploration workflow:
- 2024 UAV magnetic and gravity surveys identified a distinct 2km x 2.5km semi-circular intrusive feature interpreted as a buried intrusion and the probable heat source for the mineralising system
- Seven high-priority geophysical anomalies were defined, all interpreted to be associated with this buried intrusion
- Geological mapping and structural interpretation delineated mineralised vein systems spatially connected to the anomalies
- Systematic rock chip sampling in 2025 returned exceptional surface grades across multiple vein systems
- Environmental, heritage, and land access approvals have all been finalised, clearing the path for drilling
None of these seven anomalies has ever been drill tested. That changes when Antares Metals maiden RC drilling at Conglomerate Creek commences in late May.
The Surface Chemistry: Exceptional Grades Across Multiple Vein Systems
The geological case for a significant buried system is built on consistent, high-grade surface results across spatially distinct vein systems. Furthermore, the results are not isolated — they repeat across the prospect, accompanied by critical indicator minerals commonly associated with large-scale intrusion-related mineral systems.
Target 2 Vein System — Central Prospect
A 220m-long mineralised vein system above the Target 2 geophysical anomaly produced standout results, including the single highest-grade sample in the programme:
| Sample ID | Cu % | Au g/t | Ag g/t | Notes |
|---|---|---|---|---|
| ASR0192 | 1.44 | 0.58 | 41.7 | Quartz vein |
| ASR0193 | 1.75 | 1.77 | 52.3 | Quartz vein |
| ASR0195 | 21.30 | 1.72 | 506 | Peak sample — highest grade |
| ASR0196 | 0.74 | 2.21 | 20.5 | Notable Au |
| ASR0198 | 1.69 | 1.18 | 12.1 | Quartz vein |
Sample ASR0195 — returning 21.30% Cu, 1.72 g/t Au, and 506 g/t Ag — represents one of the more remarkable surface rock chip results seen in Australian copper exploration.
The vein system itself was identified in two sections: an artisanal working containing visible malachite hosted in quartz, and a second quartz vein approximately 100m to the west, returning 1.13% Cu, 7.4 g/t Au, and 49.6 g/t Ag (ASR0037 — previously reported).
Target 5 Vein System — 330m Northeast of Target 5 Anomaly
A 450m-long mineralised quartz vein system with a central splay zone up to 50m wide hosts at least five separate radial veins that delivered similarly compelling results:
| Sample ID | Cu % | Au g/t | Ag g/t |
|---|---|---|---|
| ASR0051 | 22.0 | 1.57 | 394 |
| ASR0057 | 8.97 | 0.61 | 218 |
Copper mineralisation at Target 5 was mapped as dominantly malachite with fine-grained chalcocite masses, also present through narrow stockwork quartz veins within sheared basalt host rock at contacts.
Critical Pathfinder Element Signature
Across both vein systems, elevated concentrations of bismuth, tungsten, antimony, and selenium — all established pathfinder elements for large-scale intrusion-related mineral systems — accompany the copper, gold, and silver values.
This multi-element geochemical signature materially strengthens the geological interpretation that a significant intrusion-related system exists at depth beneath the prospect.
Understanding the Geology: What Is an Intrusion-Related Mineral System?
Intrusion-related mineral systems are one of the most important classes of ore deposit globally, capable of hosting very large accumulations of copper, gold, silver, and associated metals. They form when heat from a crystallising igneous intrusion drives hydrothermal fluid circulation through surrounding rocks, concentrating metals along structural pathways such as faults, shear zones, and vein networks.
Why Does This Matter at Conglomerate Creek?
- The 2km x 2.5km semi-circular magnetic feature is the surface expression of a buried intrusion
- Seven discrete geophysical anomalies beneath the prospect are interpreted to be directly associated with that intrusion
- The surface vein systems — carrying world-class copper-gold-silver grades — sit above and along structures connected to these anomalies
- The presence of bismuth, tungsten, antimony, and selenium in the geochemical profile is diagnostic of intrusion-related systems and suggests the system at depth may be large
In a well-developed intrusion-related system, the highest metal grades often occur at depth, in proximity to the intrusion itself. The surface vein systems at Conglomerate Creek are potentially the distal, upper expression of a much larger buried system — which is precisely what Antares Metals maiden RC drilling at Conglomerate Creek is designed to test.
Glossary of Key Terms
| Term | Plain-Language Definition |
|---|---|
| Reverse Circulation (RC) Drilling | A drilling method where rock chips are returned to surface through the drill rods using compressed air, allowing rapid, cost-effective sampling of subsurface material |
| Geophysical Anomaly | A zone where physical rock properties (magnetism, density, conductivity) differ from the surrounding area, often indicating the presence of buried mineralisation or intrusive bodies |
| Rock Chip Sample | A representative sample of outcropping rock collected from surface, assayed to determine metal concentrations |
| Intrusion | A body of igneous rock that has crystallised below the surface; at Conglomerate Creek, the interpreted intrusion is the proposed heat driver for the mineralising system |

The Investment Case: A First-Pass Drill Test of a Genuinely Undrilled, High-Grade System
Several characteristics of the Conglomerate Creek opportunity stand out when framing the investment case.
Genuinely Virgin Ground Beneath the Anomalies
All seven geophysical anomalies at Conglomerate Creek have never been drill tested. In a mature Australian minerals province like the Mount Isa Inlier, the opportunity to be first into a coherent, multi-anomaly geophysical target suite with strong surface geochemistry is, in fact, rare.
Exceptional Surface Grade Consistency
Rock chip results above 21% copper from two spatially distinct vein systems are not routine. The consistency of high-grade results across the 220m Target 2 vein system and the 450m Target 5 vein system, combined with co-incident gold and silver, supports the geological interpretation of a systemic, intrusion-driven mineralising event rather than isolated surface enrichment.
Multi-Element Geochemical Fingerprint
The elevated bismuth, tungsten, antimony, and selenium across the prospect adds a layer of geological credibility to the intrusion-related system interpretation. Moreover, it differentiates Conglomerate Creek from simpler mineralised prospects in the region.
Approvals in Place — No Administrative Delays
Heritage agreements, land access, and all necessary environmental approvals are finalised. This removes a key uncertainty and means the drill programme can commence as planned in late May.
District-Scale Project Context
Mount Isa North spans 1,937 km² in a proven copper-gold-uranium mineral province, with multiple active prospects at varying stages of advancement. Additionally, the Quinns Project in WA adds a second district-scale exploration hub with a Plan of Work for maiden drilling already approved.
