Announcement
Miramar Resources Limited (ASX: M2R) has reported a promising start to its RC drilling program at the 8 Mile prospect, part of the Gidji JV Project north of Kalgoorlie. The first hole, GJRC029, intersected multiple gold zones and ended in mineralisation, confirming the potential extension of Northern Star’s nearby 8-Mile Dam deposit onto Miramar’s ground and reinforcing the project's prospectivity for a significant gold discovery (Figure 1).

Executive Chairman Allan Kelly commented:
“We are encouraged by the multiple gold intercepts in our first RC hole at 8 Mile,” said Executive Chairman Allan Kelly.
“The results support our view that gold mineralisation from 8-Mile Dam extends onto our ground, and we now have several follow-up targets from aircore and IP data to pursue.”
“We are planning additional geophysical surveys to refine our drilling strategy and believe 8 Mile could host significant gold potential given its location and geological setting.”
🔹 Key Highlights - A Mineral Exploration Business.
Multiple Gold Zones Intersected:
Miramar Resources’ (ASX: M2R) first reverse circulation (RC) drill hole at the 8 Mile prospect (hole GJRC029) intersected several zones of gold mineralisation and ended in gold mineralisation at 504m downhole (Figure 2).
Strategic Location Near Major Deposits:
The 8 Mile prospect lies within the Gidji JV Project, ~15km north of Kalgoorlie and adjacent to Northern Star’s 8-Mile Dam deposit (7Mt @ 1.4g/t Au for 313,977oz), confirming potential strike continuity of mineralisation.
Strong Geological Indicators:
Mineralisation is hosted within the 8 Mile mafic unit, with notable sulphide development (including arsenopyrite), elevated arsenic via portable XRF readings, and visible fuchsite, indicative of hydrothermal alteration typically associated with orogenic gold systems.
Initial Drilling Programme:
GJRC029 tested an IP anomaly thought to reflect sulphide-rich gold zones. Despite significant deviation from the planned azimuth, the hole intersected thick westerly-dipping altered mafic units and returned notable results such as:
⮞ 3m @ 2.67g/t Au from 243m (incl. 1m @ 6.51g/t)
⮞ 18m @ 0.94g/t Au from 480m (incl. 4m @ 2.83g/t and 1m @ 6.04g/t)
Next Steps and Additional Surveys:
Results are pending for four additional RC holes targeting offset IP anomalies. Infill gravity and sub-audio magnetic (SAM) surveys are being planned to refine future RC and/or diamond drilling programs.

🔹 Gidji JV Project Context
Miramar’s 80%-owned Gidji JV Project spans ~15km of the Boorara Shear Zone in WA’s Eastern Goldfields. Despite being surrounded by established gold operations (e.g., Kalgoorlie Super Pit, Kanowna Belle), Gidji has remained underexplored due to transported cover and the crosscutting Gidji Paleochannel.
Systematic aircore drilling since late 2020 has led to multiple supergene gold discoveries and several compelling bedrock targets. Miramar views Gidji as having genuine potential to evolve into a new gold camp with multiple deposits.
🔹 Exploration Update – Broader Portfolio at Gascoyne Regions Projects (Figure 3)
At the Bangemall Ni-Cu-PGE Project, Miramar is progressing with its EIS-co-funded airborne magnetic and VTEM surveys, with approximately 20% of the program completed. These surveys are designed to identify conductive anomalies associated with nickel, copper, and PGE mineralisation across the underexplored region.
At the Chain Pool SEDEX Project, the Company is preparing for a follow-up field trip focused on further soil and rock chip sampling. This work aims to advance the understanding of the high-grade sedimentary exhalative (SEDEX) system's prospective for copper, lead, zinc, and silver.
In line with its strategic focus, Miramar has also initiated the divestment of non-core assets, including the Glandore and Randalls Gold Projects in the Eastern Goldfields. These sales processes are part of the Company’s efforts to streamline its portfolio and allocate resources toward its highest priority targets.

Samso Concluding Comments
Miramar continues to present a tightly managed exploration story with a sharp geological focus. The Gidji JV Project, particularly the 8 Mile prospect, has matured from early-stage data collection into serious drill targeting, culminating in the intersection of multiple gold zones in its very first RC hole.
The 8 Mile target is compelling due to its proximity to known deposits, its geological signature, and early signs of system continuity. Ending a 504m RC hole in mineralisation is the kind of exploration result that commands follow-up.
Importantly, the Company’s layered targeting approach—combining aircore, IP, SAM, and gravity—reflects a methodical and technically sound strategy. The presence of sulphides, arsenopyrite, fuchsite, and anomalous arsenic detected by handheld XRF provides tangible indicators that this is not a one-off intercept, but part of a broader mineralised system.
This story is not about chasing hype—this is about doing the work. Some investors may say that management needs to create the hype, but as long as I have known the key management of the company, this is not in their DNA. They are all about getting into the business of mineral exploration in a cost-effective manner, and that is maximum funds into the ground and not about funding a lifestyle company.
Gidji has always had the ingredients of a significant gold system, and with each program, Miramar gets closer to unearthing its true scale. The first RC hole is just the start.
For investors seeking early-stage exposure to a potential emerging gold camp in Kalgoorlie’s backyard, Miramar is again demonstrating it has the geological smarts and the operational intent to deliver value. Miramar Resources is what I call a company that is a Mineral Exploration Business.
