First 8 Mile RC Hole Hits Multiple Gold Zones, Ends in Mineralisation at 504m
Miramar Resources has confirmed multiple gold mineralisation zones in its inaugural drill hole at the 8 Mile prospect, signalling promising extensions of the nearby 8-Mile Dam deposit. Further geophysical surveys and drilling are planned to delineate the scale of this discovery.
- First RC drill hole at 8 Mile intersects multiple gold zones
- Drill hole ends in gold mineralisation at 504m depth
- Mineralisation extends from Northern Star’s 8-Mile Dam deposit onto Miramar’s tenement
- Follow-up drilling supported by infill gravity and sub-audio magnetics surveys
- Additional exploration activities ongoing across Miramar’s project portfolio
A Promising Start at 8 Mile
Miramar Resources Limited (ASX – M2R) has delivered encouraging early results from its maiden reverse circulation (RC) drill hole at the 8 Mile prospect, part of the Gidji Joint Venture Project located just north of Kalgoorlie in Western Australia. The hole, designated GJRC029, intersected multiple zones of gold mineralisation and notably ended in mineralisation at a depth of 504 metres, confirming that the gold system extends onto Miramar’s tenement from the adjacent 8-Mile Dam deposit operated by Northern Star Resources.
Testing a Known Gold System
The 8 Mile prospect lies within a highly prospective mafic unit known to host significant gold mineralisation. GJRC029 was drilled to test an induced polarisation (IP) anomaly interpreted to be related to sulphide-rich gold mineralisation, similar to that found at Northern Star’s 8-Mile Dam deposit, which boasts a resource of approximately 7 million tonnes at 1.4 grams per tonne gold. Despite the drill hole deviating from its planned azimuth and ending further north than intended, it intersected thick, altered mafic units with multiple gold-bearing zones, highlighting the robustness of the target.
Geological Highlights and Exploration Tools
The mineralisation is associated with significant sulphide minerals, particularly arsenopyrite, which was corroborated by anomalous arsenic readings from handheld XRF instruments during logging. The presence of fuchsite, a chromium mica linked to orogenic gold systems, further supports the prospectivity of the area. Miramar plans to employ infill gravity and detailed sub-audio magnetics (SAM) surveys to refine drill targets, addressing structural complexities such as a significant fault offset near the tenement boundary.
Broader Exploration and Strategic Moves
Beyond 8 Mile, Miramar continues to advance exploration across its portfolio. The company is progressing a co-funded airborne magnetic and VTEM survey at its Bangemall nickel-copper-PGE project and preparing for further sampling at the Chain Pool sedimentary exhalative copper-lead-zinc-silver project. Concurrently, Miramar has initiated a sale process for several non-core gold projects, including Glandore and Randalls, to streamline its focus on high-potential assets.
Looking Ahead
With assay results pending from additional drill holes at 8 Mile and further geophysical data expected, Miramar is poised to deepen its understanding of this emerging gold system. The company’s Executive Chairman Allan Kelly expressed optimism about uncovering the true scale of mineralisation, underscoring the potential for a significant new gold camp within the Gidji JV Project.
Bottom Line?
Miramar’s initial success at 8 Mile sets the stage for a potentially transformative gold discovery in a prolific region.
Questions in the middle?
- How extensive is the gold mineralisation beyond the initial drill hole at 8 Mile?
- What impact will the planned gravity and SAM surveys have on refining drill targets?
- How will assay results from the other recent drill holes influence Miramar’s resource estimates?
