Miramar Resources Limited (ASX:M2R, “Miramar” or “the Company”) is pleased to announce high-grade results from sampling completed during an initial reconnaissance field trip to the Company’s new “Chain Pool” Project, in the Gascoyne region of Western Australia.
- High-grade copper, lead and silver results from “Joy Helen” prospect
- Assay results up to 5.48% Cu, 54.5% Pb and 73.48g/t Ag
- Non-Renounceable Entitlement Offer closing 5:00pm (WST) Thursday, 18 July
Samples collected from around the “Joy Helen” prospect returned high-grade results including:
- 5.49% Cu, 42.0% Pb and 73.48g/t Ag (CP003)
- 5.43% Cu, 36.7% Pb, 36g/t Ag and 0.27% Zn (CP002)
Miramar’s Executive Chairman, Mr Allan Kelly, said the Company’s Gascoyne region projects had potential for various commodities and deposit types but have been under-explored previously.
“For example, there has not been any modern and/or systematic exploration or driling at the Joy Helen Prospect despite the presence of high-grade base metal mineralisation,” he said.
“We look forward to getting this tenement granted and uncovering the potential of the Project,” he added.

Joy Helen
The “Joy Helen” Cu-Pb-Zn-Ag occurrence is located approximately 275km northeast of Carnarvon in the Gascoyne region of Western Australia, and contains historic workings and costeans over a strike length of approximately 400 metres.
Mineralisation is hosted in fine-grained dolomite of the Irregully Formation, towards the base of the Proterozoic Edmund Basin, and is interpreted to be sub-horizontal.
The mineralisation-style is interpreted to be “Mississippi Valley Type” with similarities to the Abra Pb-Zn- Ag deposit, which is also hosted in the Irregully Formation.
There is no outcrop and the geology and structure of the Joy Helen occurrence is therefore not well understood.
There has been no modern and/or systematic exploration of this prospect.
Historic drilling completed in the 1960’s intersected lead and copper mineralisation, including 1.5m @ 13.7% Pb and 1.6% Cu, however the locations of the drill holes are not recorded (WAMEX report a567).
In the 1990’s, CRA Exploration collected a limited number of rock chip samples around the workings and completed a regional stream sediment sampling programme further to the northeast, in the area now covered by the Barlee Range Nature Reserve.
In the period 2006-2009, Quadrio Resources Pty Ltd, a subsidiary of Dominion Mining Limited, conducted exploration for SEDEX gold and base metal mineralisation within their “Edmund Project” which covered the area now held as E08/3676 (WAMEX Reports a075044, a077849 and a081694).
Quadrio collected rock chip samples, including around the Joy Helen workings which returned significant copper, lead and silver results.
Miramar recently conducted a brief site visit to the Joy Helen prospect as part of a wider Gascoyne field trip and collected a limited number of samples from amongst the workings which contained varying amounts of malachite, azurite, galena, sphalerite, cerussite and possibly also barite.

Empire Metals
Investor Insight
Empire Metals (OTCQB:EPMLF, AIM:EEE) is unlocking one of the world’s largest and purest titanium deposits at its flagship Pitfield project in Western Australia. With growing global demand, a looming supply deficit, and near-term development milestones, Empire offers a compelling investment opportunity in the critical minerals space.
Overview
Empire Metals (OTCQB:EPMLF, AIM:EEE) is an Australian focused exploration and resource development company rapidly gaining international attention for its discovery and rapid development of what is believed to be the world’s largest titanium deposit.
The company is focused on advancing its flagship asset, the Pitfield project, located in Western Australia, a tier 1 mining jurisdiction. With a dominant landholding of more than 1,000 sq km, and a titanium mineral system that spans 40 km in strike length, Pitfield is emerging as a district-scale “giant” discovery with the potential to reshape the global titanium supply landscape.
Empire’s strategic focus on titanium comes at a pivotal time. Titanium is officially recognized as a critical mineral by both the European Union and the United States, owing to its essential role in aerospace, defense, medical technologies, clean energy and high-performance industrial applications. Global demand for titanium dioxide — the most widely used form of titanium — is surging due to its unmatched properties as a pigment and as a feedstock for titanium metal. Titanium supply chains are also increasingly being constrained by geopolitical risks, mine depletion and environmental challenges associated with traditional production. More than 60 percent of the global supply chain is currently concentrated in a handful of countries, notably China and Russia, creating significant vulnerabilities for Western markets.
Titanium has been designated as a critical mineral in both the EU and the US.
Against this backdrop, Empire Metals offers investors a compelling opportunity to gain exposure to a strategically vital metal through a large-scale, high-grade and clean titanium discovery. Unlike many traditional titanium sources, Pitfield's mineralization is exceptionally pure — free from detrimental amounts of uranium, thorium, chromium and other contaminants — making it ideally suited for premium, high-purity end markets. Furthermore, the mineralized zone is near-surface and laterally extensive, allowing for low-strip and scalable bulk mining with conventional processing technologies.
With more than 22,000 meters of drilling already completed and only a fraction of the mineral system tested, Empire is aggressively advancing Pitfield towards a maiden JORC-compliant mineral resource estimate, targeted for H2-2025. Alongside this work, the company is also undertaking bulk sampling and metallurgical processing to advance flowsheet design and optimize product specifications. It is also engaging with industry players to assess product suitability for premium pigment and titanium sponge markets. Empire is planning to finalize, during the current calendar year, a mining study to evaluate the potential for a low-cost strip mining approach, utilizing continuous mining techniques.
The company is supported by a seasoned leadership team with deep expertise in exploration, resource development, mining, metallurgy and capital markets — ensuring that strategic decisions are guided by both technical excellence and a strong track record of value creation.
Company Highlights
- The flagship Pitfield project is the world’s largest known titanium discovery. It’s a district-scale “giant” titanium mineral system, characterised by high-grade, high-purity titanium mineralisation exhibiting exceptional continuity.
- Titanium is in a global supply deficit and recognized as a critical mineral by the EU and US.
- Drill intercepts at Pitfield include up to 202 meters at 6.32 percent titanium dioxide (TiO2) from surface, confirming vast scale and grade.
- Empire Metals operates in one of the world’s most secure, mining-friendly jurisdictions: Western Australia.
- The company is led by an experienced, agile team, with proven expertise in exploration, mine development, and value creation across multiple commodities.
- With a number of key development catalysts planned for 2025, including a maiden resource estimate, bulk sampling for scale-up of metallurgical testwork, and product optimisation, Empire remains significantly undervalued relative to its peers.
Key Projects
Pitfield Project – A World-Class Titanium Discovery
Located in Western Australia, the Pitfield project is Empire Metals’ flagship asset and represents one of the most exciting titanium discoveries globally. Spanning an area of approximately 1,042 sq km, the project has revealed a colossal mineral system measuring 40 km in length and up to 8 km in width, with geophysical indications of mineralization extending to at least a depth of 5 km.
Pitfield’s prime location in Western Australia
Extensive drilling across the project has intercepted thick, laterally continuous zones of high-grade titanium dioxide mineralization, highlighting the system’s enormous scale and consistency.
The titanium at Pitfield occurs predominantly in the minerals anatase and rutile within a weathered, in-situ cap that begins at surface. These minerals are exceptionally pure, often exceeding 90 percent titanium dioxide. They are free from harmful amounts of contaminants like uranium, thorium, chromium and phosphorus — qualities that are likely to make the deposit uniquely suitable for premium, high-purity titanium applications in aerospace, defense and clean technologies.
Pitfield is strategically located near the town of Three Springs, approximately 150 km southeast of the port city of Geraldton. The project benefits from direct access to essential infrastructure, including sealed highways, rail lines and an available water supply. This connectivity significantly enhances development potential by reducing logistics costs and simplifying future project build-out. Moreover, the Western Australian government actively supports critical mineral development, and Empire is operating within a stable, mining-friendly jurisdiction known for streamlined permitting and investment security.
Empire has completed more than 22,000 meters of drilling, confirming standout titanium dioxide (TiO2) results such as 154 meters at 6.76 percent TiO2, 148 meters at 6.49 percent TiO2, and 150 meters at 6.44 percent TiO2. Notably, mineralization remains open at depth in all tested zones, and to date, only around 5 percent of the interpreted system has been drilled. This underscores the immense upside potential for resource expansion.
The project’s development advantages are equally compelling: the mineralization is near-surface and amenable to simple, bulk mining methods with conventional processing. Its location in a tier-one mining jurisdiction offers access to infrastructure, a skilled workforce and strong regulatory support.

Pitfield is advancing toward a maiden JORC-compliant mineral resource estimate, expected by H2-2025. The project is already being recognized as a potential cornerstone asset in the global titanium supply chain.
Other Projects
In addition to Pitfield, Empire Metals maintains a portfolio of early-stage exploration assets offering optionality and exposure to other strategic and precious metals. Empire holds interests in two Western Australian projects — the Walton and Eclipse gold projects — both situated in historically productive mineral belts. While these assets are not the current focus, they contribute exploration upside and optionality within the company’s broader strategy.

175m @ 2.5% Copper from 7.6m, Hole Ends in 4.46% Copper & Open at Depth Danvers Drilling Delivers a Globally Significant Copper Intersection
- Further assay results confirm and validate the strategy to explore previously untested high-grade zones and vertical depth extension of mineralisation at Danvers
- Highlights from DAN25008:
- 175m @ 2.5% Cu & 8.66g/t silver (Ag) from 7.6m, including 14m @ 7.55% Cu & 25.8g/t Ag from 138m
- the last 60m of the hole averaged 3.9% Cu & 14.96g/t Ag to final depth of 182.88m
- hole ended in mineralisation with the last 1.5m sample recording 4.46% Cu & 11.58g/t Ag, open at depth
- DAN25001 returned 52m @ 1.16% Cu & 3.43g/t Ag from surface, including 7.6m at 3% Cu & 9.5g/t Ag from 18.28m
- Drilling demonstrates potential for significant expansion to historic non-compliant resource. With the initial objectives of Danvers drilling achieved, to begin to understand the significance of this discovery, new drilling data will feed into a maiden JORC compliant mineral resource
- Mineralisation remains open in all directions. Follow up diamond drilling now being planned to drill out the mineralisation boundaries at Danvers and begin testing of the massive sedimentary structure at Hulk
- The next five (5) assays along strike from DAN25008 are due in the coming weeks
“DAN25008 was prioritised for assay due to the abundance of visual sulphides observed during drilling, and these results have underpinned our confidence in those visuals prevalent in the Company’s prior work. We believe this drill hole ranks among the most significant copper intersections globally within the last 50 years and comfortably sits within the top 10 globally reported “grade-metre” copper results.
This discovery and outstanding results from Danvers is a clear testament to our technical team’s expertise and geological understanding, in particular the professionalism and persistence of Olga Solovieva and Sam Vaughan.
Our improved geological understanding of the Danvers area indicates a mineralised system that extends from surface over more than 175m vertically and potentially 7km in strike length - both to the northeast and southwest, providing scope for further high-impact intercepts from upcoming drilling. With our work updating the geological understanding at Danvers, we adapted our drill targets and DAN25008 resulted in mineralisation at least 30 metres below historical limits, with the hole terminating in high-grade copper mineralisation - suggesting considerable additional potential at depth. The increase in grade toward the bottom of the hole is encouraging and is validation of our methodology.
To illustrate the magnitude of this result, the DAN25001 intercept of 52m at 1.2% Cu - a strong result in its own right - now appears modest when viewed alongside the 175m @ 2.5% Cu from DAN25008. In the context of global copper supply constraints, the Company is well positioned to leverage these results with mineralisation from surface, supporting potential open pit mining activities and an open water port less than 80km from the deposit.
