Assays of samples from the drilling announced recently1 by EMU NL (ASX:EMU) (“EMU” or “the Company”) confirm significant scale rare earth mineralisation with high values for TREO, HREO and MREO2 at the 100% owned Condingup REE Project near Esperance WA.
The wide-spaced aircore drilling programme targeted deep clay traps and paleochannels, interpreted from EMU’s passive seismic geophysics survey, returned significant TREO results up to 2,513ppm over multiple kilometres and over wide drilling intervals. This proof-of-concept drilling effectively demonstrated that substantial concentrations of REEs are hosted in the deeper clay trap zones within the weathering profile overlying fresh host Booanya granites.
HIGHLIGHTS
- Extensive high grade assay results recorded from standard 4m composite samples up to 2,513pmm Total Rare Earth Oxides (TREO)
- High value Magnetic Rare Earth Oxide (MREO) ratio to TREO of 21% (average for drilling programme) extending to a maximum of 40.7% at Merivale Rd
- Heavy Rare Earth (HREO) ratio of up to 53.08%
- The aircore programme targeted only a minor portion of viable clay trap sites and deeply weathered Booanya granites within the 1,560 square kilometre project, indicating the vast scale of prospectivity available for further testing
- First phase aircore drilling programme demonstrated continuity of grade and thickness over multiple kilometres in the wide-spaced drill programme with mineralised lenses running up 6-8kms in length
- Anomalous grade >300ppm TREO values intersected in 33 of the 34 holes drilled over significant intercepts up to a maximum 59m vertical drill intercept
- High grade >750ppm TREO values intersected in 67% of holes drilled. Flat-lying REE zones located in relatively shallow thick clay zones immediately above fresh granite lithologies
Significant high-grade clay-hosted rare earth intersections include:
The “proof of concept” roadside aircore drilling programme tested three main targets at Kettles- Parmango, Merivale and Baring Roads where interpreted bedrock mapping indicated deep clay traps within the prospective Booanya Suite granitic intrusives. The three drill targets were tested by continuous 4m composite sampling through the complete weathering profile from surface to bedrock. Overall, the drilling tested only a very small proportion of the substantial 1,560 square kilometre Condingup REE Project, leaving scope for multiple target areas remaining for follow-up work (see Figure 1 – Drill Collar Location Plan).

Results
The Condingup aircore drilling programme and multielement analysis of the sampling has confirmed significant grades of REE mineralisation over wide intercepts in this “first pass” drilling programme designed to test the proof of concept.
The assay results returned anomalous grade >300ppm TREO values in 33 of the 34 holes completed, demonstrating the prospectivity of the region and the fertility of the host rocks. Consistent wide mineralised intercepts confirmed the Condingup REE Project as a project that stands “head-to-head” alongside its peers in the emerging globally significant Esperance clay hosted REE province.
The distribution of anomalous REE elements generally occupy a variable but wide interval of clays and saprolite immediately above the granite bedrock. The width of intercepts in the vertical drilling range up to 59m (Hole 23CAC019) and the lateral extensions of these “lenses” reach at least 6-8km, which points to significant project prospectivity and economics.

Investor Insight
EMU NL is an Australia-focused base and precious metals exploration company offering a compelling opportunity in the highly lucrative copper space. A strategic focus on delineating a potential large-scale copper porphyry system at its Fiery Creek copper deposit in Northern Queensland, combined with a leadership team of significant global experience and expertise, and an upward trending copper market, all make EMU NL worthy of considerable consideration for any investors looking at the copper sector.
Overview
EMU NL (ASX:EMU) is an ASX-listed precious and base metals exploration company with three projects in Queensland, Australia: Georgetown, Badja and Sunfire. EMU’s primary focus is accelerating exploration at the highly promising Fiery Creek prospect, located within the Georgetown project in Northern Queensland.
Australia is one of the most attractive regions for mining, according to the Fraser Institute. It ranks Queensland as the 13th most attractive destination for mining investment.
In 2023, Queensland's mines yielded 12.6 tons of gold, positioning it as Australia's fourth most prolific state for this precious metal. The company's presence in relatively attractive mining jurisdictions positions it to capitalize on opportunities in Australia's resource sector and deliver sustainable returns to its shareholders. The recent fundraises of A$1.45 million have provided sufficient funding to advance its exploration projects.
Gold and copper continue to demonstrate bullish trends. Various factors are driving the surge in copper prices, including demand patterns such as upgrades in utility grids, the increasing use of copper in electric vehicles, and housing construction. Additionally, the growing energy demand from data centres powering AI applications and servers contributes to the increased need for copper. Both gold and copper prices have hit their all-time high in 2024, which also enhance the prospects for junior miners to progress their projects and potentially secure financing easily.
Key Projects
Georgetown Project
The Georgetown project tenements span 850 sq. km. in North Queensland and comprises three exploration permits: Georgetown, Perpendicular Peak and the Fiery Creek copper prospect. Of these, Fiery Creek is the most promising and the current exploration interest for EMU.
The Georgetown project is located in a resource-rich yet under-explored region in Queensland’s far north, situated within the Georgetown mining district, with a significant history of mining activities and mineral discoveries.
EMU has identified the Fiery Creek copper prospect as a potentially massive-scale copper porphyry system within the 29 sq. km. Yataga Igneous complex. In the middle of 2023, EMU's reconnaissance efforts at Fiery Creek yielded numerous instances of heightened copper and polymetallic values. EMU conducted additional sampling to further assess the potential of the Fiery Creek prospect.
The work confirmed the significant, large-scale potential of the Fiery Creek copper prospect. It identified additional high-priority targets within the Yataga Granitoid complex, revealing polymetallic rock chip values reaching up to 0.27 parts per million (ppm) gold, 460 ppm silver, 1.9 percent bismuth, 23.5 percent copper, 43 ppm indium, 2.7 percent lead, and 341 ppm antimony. Similarly, values of 0.13 ppm gold, 44 ppm silver, 0.28 percent bismuth, 13.5 percent copper, 89 ppm indium, 1.62 percent lead, and 667 ppm antimony were recorded at Yataga South.
Initial fieldwork has provided strong indications of a potential large-scale copper porphyry system at Fiery Creek. EMU is planning further geological mapping, systematic geochemistry and a geophysics survey to delineate the indicated porphyry system.
Badja Project
The Badja project is located 32 kilometres southeast of the township of Yalgoo and covers an area of 870 hectares. The project's tenements include a centrally granted mining lease covering 7.3 hectares, an adjoining mining lease application covering 279.3 hectares, and a granted exploration license covering 590.3 hectares. EMU’s previous drilling work has identified areas that are prospective for high-grade gold, tungsten and lithium.
EMU is evaluating options to maximize the value of the project, either through sale or retention.
Sunfire Project
Sunfire is a nickel, copper and PGE exploration project in Western Australia. The project is currently awaiting permission from the Western Australian government to allow drilling activities in the area within the State forest. EMU has fulfilled all necessary environmental requirements for accessing these areas within the project and initiated onsite exploration activities. However, there has been no significant advancement to date, and government departments have not indicated the likelihood of granting drilling consent.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
