Miramar Resources Limited (ASX:M2R, “Miramar” or “the Company”) advises that it has identified multiple very large uranium targets within the Company’s 100%-owned Bangemall Projects, in the Gascoyne region of Western Australia.
Regional radiometric data shows multiple very large and high-amplitude uranium anomalies that stretch over at least 100km of strike and across several of Miramar’s tenements (Figure 1).
Miramar’s Executive Chairman, Mr Allan Kelly, said the Company’s strategic Bangemall landholding has potential for multiple commodities and deposit types.
“Proterozoic orogens throughout Australia and worldwide host many large base and precious metal deposits, and we believe the Capricorn Orogen should be no exception,” Mr Kelly said.
“Whilst our current focus is on exploring for Norilsk-style nickel, copper and platinum group elements at our Mount Vernon and Trouble Bore Projects, we have a very long list of attractive exploration targets we aim to systematically explore,” he added.

Cheyne Springs Target
A well-defined, 60-kilometre-long uranium anomaly is located within the Cheyne Springs Target towards the northern edge of the Edmund Basin, at the contact with the older Ashburton Basin rocks (Figure 2).
The very large radiometric anomaly has been virtually unexplored except for a few wide-spaced rock chip samples that returned results up to 246ppm U (i.e. 290ppm U3O8) (WAMEX Reports a78053, a81036, a91967 and a92435) (Figure 3).
The Company is working towards grant of the tenement applications at Cheyne Springs, and the adjacent Blue Bar Target.

Empire Metals Limited Announces Team Expansion & Bulk Met Testing Commences
Highlights
- Strategic Appointments to Accelerate Development
Empire has appointed Mr. Alan Rubio as Study Manager and Mr. Pocholo Aviso as Hydro-metallurgist. These appointments are aligned with the Company's objective to evaluate mining scenarios, optimise product development, assess commercial process flowsheet options and progress the Project toward a feasibility study. - Mr. Alan Rubio, an engineer and seasoned Study and Project Manager with over 28 years' experience working within the resources sector developing and evaluating mining projects, will lead the assessment of mining, infrastructure and oversee key economic studies to deliver a robust project development plan.
- Mr. Pocholo Aviso, an experienced hydro-metallurgist with a background in the TiO₂ pigment industry (including roles at Tronox and BHP's Kwinana Nickel Refinery), will manage the titanium product development programme, focusing on product optimisation, process flowsheet designs and evaluating market pathways.
- Partnership with Strategic Metallurgy Pty Ltd:
Empire has also partnered with Strategic Metallurgy, a highly respected, Perth-based metallurgical consultancy. The firm will provide oversight of the metallurgical testwork programme and technical guidance to the Company's internal metallurgists and process design engineers, helping transition from bench-scale process development to pilot-scale testing.
- Bulk-Scale Testwork:
The Company has commenced bulk metallurgical testwork that will produce significant quantities of mineral concentrate to support large-scale beneficiation testing and, for the first time, enable the supply of bulk product samples to prospective end users. In addition, this testwork will provide critical technical information for the development of a commercial process flowsheet.
These key appointments advance the Company toward confirming project economics and assessing mine design, process flowsheets and product options-critical steps in the development pathway to commercial mine production.
Commenting on the announcement, Shaun Bunn, Managing Director, said:
"I am delighted to welcome Alan and Pocholo to our team. Their technical expertise will be invaluable as we move toward defining the economic potential and product strategy for Pitfield. Building a strong in-house team has been key to our progress so far, and these appointments mark an important next step.
"We are also very pleased to be working with Strategic Metallurgy, whose reputation and experience in process development will significantly strengthen our metallurgical programme. The timing is ideal, with large-scale metallurgical testing now underway, including ore scrubbing and spiral gravity separation, using bulk samples collected earlier this year."
Process Development Update
A large-scale metallurgical testwork programme, involving mineral separation techniques that require bulk feed samples, between approximately 0.5 to 1.5 tonnes each, has commenced using the material collected from the February 2025 Air Core drilling. The programme includes ore scrubbing, desliming and gravity spiral testwork. Alternative gravity separation unit processes, such as jigs and up-current classifiers, are also being evaluated.
Flotation testwork is also being carried out on the fines fraction, separated in the desliming step. As part of this programme, bulk mineral concentrates will be produced for downstream processing, testing both hydrometallurgical and product finishing flowsheet concepts. This will allow a consistent, common mineral concentrate stream to be assessed across the range of flowsheet options that are being considered downstream of the mineral separation step.

About Empire Metals Limited
Empire Metals is an AIM-listed and OTCQB-traded exploration and resource development company (LON:EEE)(OTCQB:EPMLF) with a primary focus on developing Pitfield, an emerging giant titanium project in Western Australia.
The high-grade titanium discovery at Pitfield is of unprecedented scale, with airborne surveys identifying a massive, coincident gravity and magnetics anomaly extending over 40km by 8km by 5km deep. Drill results have indicated excellent continuity in grades and consistency of the in-situ mineralised beds and confirm that the sandstone beds hold the higher-grade titanium dioxide (TiO₂) values within the interbedded succession of sandstones, siltstones and conglomerates. The Company is focused on two key prospects (Cosgrove and Thomas), which have been identified as having thick, high-grade, near-surface, in-situ bedded TiO₂ mineralisation, each being over 7km in strike length.
An Exploration Target* for Pitfield was declared in 2024, covering the Thomas and Cosgrove mineral prospects, and was estimated to contain between 26.4 to 32.2 billion tonnes with a grade range of 4.5 to 5.5% TiO2. Included within the total Exploration Target* is a subset that covers the in-situ weathered sandstone zone, which extends from surface to an average vertical depth of 30m to 40m and is estimated to contain between 4.0 to 4.9 billion tonnes with a grade range of 4.8 to 5.9% TiO2.
The Exploration Target* covers an area less than 20% of the overall mineral system at Pitfield which demonstrates the potential for significant further upside.
Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal or pigment quality product at Pitfield, to realise the full value potential of this exceptional deposit.
The Company also has two further exploration projects in Australia; the Eclipse Project and the Walton Project in Western Australia, in addition to three precious metals projects located in a historically high-grade gold producing region of Austria.
*The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. See RNS dated 12 June 2024 for full details.

Nobel Resources Announces Additional Results at the Cuprita Project, Atacama Region, Chile
Nobel Resources Corp. (TSX – V: NBLC) (the “Company” or “Nobel”) is pleased to provide an update on its ongoing exploration at the Cuprita Project (the “Project” or “Cuprita”) in Atacama Region, Chile. Following the recent identification by Nobel geologists of a leach cap with characteristics strongly associated with porphyry copper-(gold) deposits in the region at Cuprita, including associated highly anomalous copper in soils and bedrock, the Company has additionally confirmed:
- the existence of an IP chargeability and resistivity anomaly typical of porphyry copper deposits in the region; and
- the presence of highly anomalous copper chip samples from outcrops associated with the leach cap.
The geological features being identified by Nobel field work at Cuprita demonstrates the Project is highly prospective.
According to Vern Arseneau, COO of Nobel, “After only a few short weeks in the field, Nobel Geologists have identified key characteristics of a shallow mineralized porphyry system at Cuprita. The leach cap, IP anomaly, significant copper bearing rock chips and the copper in soil anomaly are all located adjacent to a ground magnetic low. These traits are situated near the intersection of a major north-northeast striking fault structure with numerous northwest striking quartz veins with copper oxides. Intersecting major faults is a common, if not essential, structural control for the emplacement of copper-gold porphyries in the region (Figure 3). This is essentially the complete suite of important indicators used when identifying productive porphyry copper systems, combined with a leach cap in one of the most important porphyry copper belts globally indicate excellent potential for a mineralized porphyry deposit at the Cuprita project.”
The IP survey was carried out by Argali Geophysical SA during November 2018 and consisted of three E-W lines across the area of the recently identified leach cap. Survey parameters were 100m spaced dipoles with an estimated depth penetration of 700m at N=27. The top of the IP anomaly, based on this data, is estimated to be approximately 200meters below surface. (Figure 3; line 7055700N). All three lines exhibit a similar chargeability/resistivity response and the anomaly remains open to the North and South.
The chargeability anomalies from 7 to 9 mV/V are in line with many of the porphyry copper deposits near Inca de Oro which are notoriously low in pyrite and therefore in chargeability. Chargeability of less than 10 mV/V has been observed at many deposits local to Cuprita. Similarly, field observations by Nobel geologists have also confirmed the general lack of pyrite in altered rocks at Cuprita.
Rock chip sampling of mineralized structures associated with the leach cap, anomalous soil samples and the ground magnetic anomalies returned highly anomalous copper values ranging from 0.25 to 3.46% Cu. Many of the rock samples contain remnant copper sulfides, such as Chalcocite, Chalcopyrite and locally Bornite (Figure 1). Additionally, a sample taken 500m to the northeast, where QZ vein stockwork with disseminated chrysocolla outcrops with a grade of 2.06% Cu (Figure 2) signifying the potential for a large extensive system.
Figure 1: Rock sample with Chalcopyrite and Bornite grading 1.36% copper associated with the leach cap.
Figure 2: Sample of copper-rich stockwork of quartz and chrysocolla grading 2.06% copper from 500 meters northeast of previous sample.
According to Larry Guy, CEO, “Nobel geologists believe that this newly identified geological / geochemical evidence along with the geophysical compilation points to potential for a large mineralized porphyry at shallow depth covering the area between the anomalous soil results to the South and extending more than 2 kilometers North to the previously reported ground magnetic lows. (Figures 3 and 4; map and cross section and Figure 5 conceptual geological model).
Geologically, Cuprita is part of the Metallogenic Paleocene Porphyry Copper Belt that hosts several major porphyry copper deposits, such as El Salvador, Cerro Colorado, Spence, Sierra Gorda, Fortuna, as well as several gold deposits. Recent field work at Cuprita has focused the targeting for forthcoming drill programs.

Empire Metals Limited Announces Completion of MRE Drilling Campaign
- 180 drill holes completed at the Thomas prospect, comprising:
- 140 Air Core ('AC') drill holes for a total of 6,360 metres;
- 40 Reverse Circulation ('RC') drill holes for a total of 3,776 metres;
- Total metres drilled: 10,136
- Drilling was conducted on a systematic 400m by 200m grid covering over 1,352 hectares and was designed to support the initial MRE as well as providing key data for economic evaluation studies.
- The Thomas Prospect was selected as the basis for the maiden MRE due to the extensive, thick and high-grade titanium mineralisation hosted within the broad, in-situ weathered zone.
- This campaign marks a major milestone in the development of Pitfield, laying the foundation for a globally significant MRE and enabling the identification of near-surface, high grade zones to support the development of mine planning and ore scheduling as part of upcoming economic evaluation studies.
Shaun Bunn, Managing Director, said: "We are very pleased to have completed this important drilling campaign on time, on budget and without safety incident. With drilling now complete, our focus turns to resource modelling and progressing Pitfield towards its maiden Mineral Resource Estimate, which is a key milestone as we look to bring this globally significant titanium project to commercialisation, maintaining the ambitious development schedule we have delivered over the past two years."
MRE Drilling Programme
With the completion of the current drill campaign, the largest undertaken by the Company to date, total drilling at Pitfield has now surpassed 32,000m across 382 holes, providing a robust foundation for geological modelling, resource definition (refer Figure 1) and initial economic evaluation work.
Since commencing the maiden drilling campaign at Pitfield on 27 March 2023 Empire has completed 382 drill holes for a total 32,265 metres comprising:
- 17 Diamond drill holes for 2,704 m
- 140 RC drill holes for 18,764 m
- 225 AC drill holes for 10,797 m.

May-June 2025 Campaign
The location and spacing of the current RC and AC drillholes were designed, with the input of mineral resource consultants Snowden-Optiro, to provide the necessary drill assay data density to allow the preparation of an MRE at the Thomas Prospect.
The completed drill campaign consisted of 140 AC drillholes, on a 400 x 200m drillhole-spaced grid with an average forecast depth of 45.4m, for a total of 6,360 metres, and 40 RC drillholes within the AC drilling grid, to an average depth of 94.4m, for a total of 3,776 metres. The overall drillhole grid extends 5.2km by 2.6km and totals an area of 1,352 hectares (refer Figure 2).
Figure 2. RC and AC drill hole collar locations within the Thomas Prospect priority area.
During the campaign all drill holes were subsampled on a 2m interval, resulting in over 5,000 drill samples being collected, logged by our on-site team of geologists and then prepared for shipment to Intertek's Perth based analytical laboratory. As of the end of June all drill hole and QA/QC samples have been delivered to Intertek for geochemical analysis and assaying.
