EMU NL (“ EMU ” or “ the Company ”) is pleased to advise that results from multi-element assays have confirmed the Company’s holdings over Booanya suite granites at its 100% owned Condingup Project, near Esperance WA, to be highly fertile for rare earth elements, with outcropping rock samples reporting up to 2,124 ppm TREO (Total Rare Earth Oxides) with 25% MREO[1] (Magnetic Rare Earth Oxides). See the section headed “Rare Earth Elements” below for explanation of the significance of these numbers.
Highlights
-
Condingup Project confirmed to host desirable Magnetic and Heavy REE minerals
-
Surface rock samples contain up to 2,124 ppm TREO
-
Average MREO to TREO content of granites sampled 25%
-
Significant HREO[2] to TREO content of 12.7%
Assays from Booanya granite rock samples, taken during EMU’s reconnaissance at the Condingup Project, report a contained, significant 25% MREO with 12.7% HREO . This indicates excellent exploration upside for large-scale low-cost recovery clay hosted REE (Rare-Earth Elements) deposits.
Magnetic and Heavy rare earth element concentrations are highly desirable for their use in the strongest and most affordable permanent magnets. Higher values of Nd-Pr & Dy (NeodymiumPraseodymium and Dysprosium, key elements in rare earth magnets), recorded in the samples, provide significant encouragement for EMU’s Condingup Project given the high value of those elements.
Condingup Project
The Condingup Project is located just 35kms southeast of ASX:OD6 Splinter Rock Project which is achieving success in a similar setting within the REE enriched Booanya suite granites. EMU’s Condingup Project is situated just 60kms from the port of Esperance and essential infrastructure all accessible by sealed roads. Esperance is projected to become a central hub for major renewable energy and green hydrogen production and is located within a well-regarded exploration/mining support jurisdiction.
Reconnaissance Work
A total of 8 rocks were collected and assayed from a reconnaissance programme in December 2022, including 3 rocks which were identified to be Booanya granite samples. The Booanya granite samples all reported greater than 1,000 ppm TREO, with results ranging between 1,142 ppm TREO – up to 2,124 ppm TREO . Other rock types collected included: aplite, ironstone, vein-quartz and limestone.

The primary focus of the reconnaissance sampling was to collect clay samples from dam surfaces from various farms in the region. The earth dams are constructed and maintained utilising earthmoving equipment that excavates clay zones from depths of up to approximately 10m. The excavated clays have been largely identified to be located within the “ transported ” cover zone, at surface, which overlays the potentially more fertile, deeper saprolite “ clay ” layers. EMU determined significant anomalism from assay results in these leached clay samples with REE TREO reporting up to 518ppm . Results from the sampled clays, provide EMU with excellent contour vector potential for deeper rare-earth clay enrichment for drill targeting beneath the surface sands and gravels in the Condingup area, expected to reflect oxide and enriched clay development. (Figure 1).
Mineralisation Model
Given the exploration success of near neighbour, OD6 Metals at Splinter Rocks, and the results from EMU’s first pass reconnaissance work, EMU expects to identify REE supergene concentrations in clay zone traps through upcoming drilling and exploration vectoring.
Due to geological weathering processes, any clay traps intersected in drilling will likely contain greater concentrations of TREO than the numbers reported in the Booanya granite rock samples detailed in this release highlighting the “fertility” significance of the rock sample results reported herein.

Sample Locations
The 3 Booanya suite granite rock samples tested reflect significant REE enrichment. Two of the three REE enriched granite samples were collected from the southern Booanya granite intrusion whilst the third REE enriched granite rock was collected from the eastern Booanya granite intrusion. (Figure 2). Whilst no granite surface samples were collected from the northern Booanya granite intrusion, a limestone sample collected from above the clay horizon near a dam site, contained significantly anomalous TREO of 468ppm . Limestone is known to act as a “sponge” for metallic minerals, making this sample a very good REE enrichment indicator.

The multi-element assays of the Booanya granite rock samples indicate that the anomalous REE’s are hosted within fractionated, metasomatized, alkaline Booanya suite granites. Globally, fractionated alkaline systems are known to be associated with significant REE deposits.

Follow Up Work Programme
EMU has initiated the necessary (and often drawn out) administrative processes to acquire access for planned air-core drilling over the northern, southern, and eastern granite intrusive areas, and a follow up rock chip sampling programme in order to further expand the fertility vectors of the outcropping Booanya suite granites.
Booanya suite granites are recognised to host clay enrichment evolved from their weathering process, as indicated from work completed by neighbouring explorers. The deeper clay zones overlaying and adjacent to Booanya suite granites appear to host higher concentrations of REE.

EMU is currently reviewing all publicly available open-source information including hydrochemistry, radiometrics and (reprocessing) magnetic data to assist in determining vectors for deeper clay horizons over prospective zones to establish and refine its drill targets.
Rare Earth Elements
Rare earth elements (REEs) comprise a group of 17 elements found in the earth’s crust. They are becoming increasingly important for the long-term viability of many modern technologies such as electric cars, wind turbines, smart phones, and many other applications.
When reporting values for REE’s, exploration companies will often quote Total Rare Earth Oxide (TREO) values. TREO values greater than 1,000ppm from rock chips are considered highly anomalous. REE’s can be further categorised into two distinct groups. Light Rare Earth Elements (LREE’s) and Heavy Rare Earth Elements (HREE’s). The HREE’s are considerably less abundant and hence much more valuable than LREE. (Figure 3.)
TREO values are obtained from the summing of individual rare earth elements with a standard formula applied to the assayed result to arrive at a total value (ppm). The same process is applied to obtaining the value of the HREE’s and LREE’s– whereby the heavy and light individual rare earth elements are summed up to give HREO and LREO values. Comparing the ratio of HREO to TREO (or Heavy Rare Earth Oxide value to Total Rare Earth Oxide value ) is very useful in determining the potential value and prospectivity of a rare earth project. A ratio of greater than 10% is regarded as significant. Rock chip samples from Condingup are more than 10% (with a ratio of 12.7%) confirming the prospectivity of this project.
In the same way HREO is calculated, MREO (or Magnetic Rare Earth Oxide) gives a value of the magnetic rare earth oxide for a group of selected elements. A ratio of 20% MREO to TREO is considered significant. Once again, the MREO ratio from rock samples at Condingup (25%), giving EMU further encouragement for the project.
In evaluating rare earth projects, it is essential to consider the processes involved to extract the elements. Rare earth elements are difficult to separate from each other and, moreover, they are often associated with radioactive elements such as uranium and thorium making exploration, waste disposal, mining and processing problematic.
Distinguishing advantages of clay hosted rare earth deposits over hard rock deposits are that they are considerably cheaper to extract and has a lower environmental impact.
EMU’s Condingup Project is a REE enriched, clay hosed, multiple, shallow deposit project which makes exploration and any resultant mining and processing less complex and more environmentally acceptable.

| In cases where ‘industry standard’ work has | |||
| been done this would be relatively simple | |||
| (e.g. ‘reverse circulation drilling was used to | |||
| obtain 1 m samples from which 3 kg was | |||
| pulverised to produce a 30 g charge for fire | |||
| assay’). In other cases, more explanation | |||
| may be required, such as where there is | |||
| coarse gold that has inherent sampling | |||
| problems. Unusual commodities or | |||
| mineralisation types (e.g. submarine | |||
| nodules) may warrant disclosure of detailed | |||
| information. | |||
