Significant REE Values, Project Footprint
Extended - Condingup, Esperance WA
4 May 2023
----- End of picture text -----
EMU NL (ASX: EMU) (“ EMU ” or “ the Company ”) is pleased to announce results of its highly successful Stage 2 Rock Chip Reconnaissance Survey and the making of applications to extend the Project footprint at its 100% owned Condingup REE Project within the Esperance REE Province of Western Australia.
HIGHLIGHTS
-
EMU’s Stage 2 Rock Chip Reconnaissance Survey has confirmed and extended the Rare Earth Element ( REE ) mineralisation footprint with highly anomalous REE values recorded from outcropping Booanya suite granites.
-
Rock Chip assays results have confirmed the extensive surface TREO ( Total Rare Earth Oxides ) REE mineralisation with assay results including 941 ppm TREO, 1,089 ppm TREO, 1,205 ppm TREO and 1,242 ppm TREO.
-
High value Magnet Rare Earth Oxides ( MREO ) represent an average of ~22% of TREO grade from 28 rock chip samples.
-
Rock Chip Assay results confirm EMU’s Booanya suite granites to be highly fertile for rare earth elements with the potential to host significantly enriched rare-earth minerals in clay.
-
EMU has applied for an additional 765 square km of highly prospective Exploration Licence ground, taking the overall exploration package at the Condingup REE Project to 1,560 square km of Exploration Licence area – further increasing its major strategic footprint in the Esperance REE Province.
-
On a regional scale, the western, central and eastern granitic zones remain untested with numerous, extensive strong exploration targets varying from 14.1km to 18.3km in strike length .
-
EMU is currently planning a maiden aircore drilling programme to ascertain mineralisation in target clay REE enriched horizons.

Following the highly successful December 2022 Stage 1 Rock Chip Reconnaissance Survey and surface clay sampling programme[1] , which reported significant 25% MREO as percentage to TREO and 12.7% HREO[2] as percentage to TREO assay results, the Company undertook a more extensive surface rock chip sampling programme targeting Booanya style granite outcropping.
Assay results from the Stage 2 Rock Chip Reconnaissance Survey iden�fied highly anomalous REE zones, clearly demonstra�ng strong underlying host rock fer�lity over the Condingup REE Project. Based on these very early-stage explora�on results, the Project has all the hallmarks to poten�ally host significant economic, clay hosted REE mineralisa�on.
Results from this sampling programme encouraged EMU to immediately make applica�ons for an addi�onal 765 square kms of explora�on licence ground substan�ally adding to the overall project footprint over the Booanya style granites, associated drainage profiles and adjacent weathered clay zones.
As part of EMU’s assessment of the intrusive Booanya suite granites, the regional magne�c survey has outlined a direct correla�on between strong magne�c vectors and highly elevated REE assays, delivering a number of walk-up explora�on targets. These targets are very extensive in area and provide substan�al opportuni�es for drill tes�ng.
Peter Thomas, EMU’s Chairman, comments
“These are stunning results from the rock chip sampling programmes and are extremely encouraging. The results shine a bright light on EMU’s Condingup REE Project and iden�fy it as being a “dead ringer” to OD6’s Splinter Rocks project. The intrusive Booanya granite suite has proven to be a significant indicator of REE fer�lity in the eastern Esperance REE Province.
Following successful high value TREO results and the strong possibility of higher enrichment in the surrounding clays, EMU immediately made strategic applica�ons for an addi�onal explora�on tenement area, bringing the 100% owned Condingup Project area to an aggregate 1,560 square kilometres thus advancing EMU’s status as a significant REE player in the Province.
The impending maiden aircore drilling programme is envisaged to report higher concentra�ons of REE hosted in clay zones adjacent to, and overlaying, the weathered granite suite”.
Stage 2 Rock Chip Reconnaissance Survey
A total of 28 rocks were collected during March and assayed in April 2023. The primary focus of the reconnaissance sampling was to collect clay samples from road cu�ngs and surfaces from various farms in the region. The mul�-element assays of the granite rock samples indicate that the anomalous REEs are hosted within frac�onated, metasoma�zed, alkaline Booanya suite granites. Globally, frac�onated alkaline systems are known to be associated with significant REE deposits.

Conceptual Mineralisa�on Model
Given the significant exploration success of near neighbour, OD6 Metals at Splinter Rocks, and the results from EMU’s Rock Chip Reconnaissance Surveys, 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 concentra�ons of TREO than the numbers reported in the Booanya granite rock samples detailed in this release highligh�ng the “fer�lity” significance of the rock sample results reported herein.
EMU's Condingup REE Project is represented by the discovery of clay hosted rare-earths in an exploration location which has been previously overlooked by past explorers whose primary focus was exploration for industrial minerals. EMU has identified the project through the compilation, review, and processing of publicly available data, combined with the application of geological first principles which includes the collection and assaying of more than 58 regional surface rock and 39 surface clay samples.

Follow Up Work Programme
EMU has commenced planning its maiden aircore drill programme at Condingup which will test deeper clay zone targets iden�fied from reprocessed aero magne�c survey data. The drilling programme target areas will focus on interpreted deeper “clay traps” which EMU hypothesises host high grade REE deposi�ons. Drilling will be scheduled following the finalisa�on of necessary administra�ve access protocols. Further to drilling programmes, EMU is reviewing the possibility of a geophysical Airborne Electromagne�c Survey ( AEM ), a methodology that has shown significant promise at other clay hosted projects in the area, to iden�fy clay depths over basement rock. An AEM survey has the poten�al to unlock mineralised zones and provide defini�ve vectors for drill targets.

About the Condingup Rare Earth Project
The 100% owned Condingup Rare Earth Project is located just 35kms southeast of ASX:OD6’s Splinter Rock Project which is achieving success in a similar geological se�ng within the REE enriched Booanya suite granites. EMU’s Condingup Project is situated just 60kms from the port of Esperance and other essen�al infrastructure all accessible by sealed roads. Esperance is projected to become a central hub for major renewable energy and green hydrogen produc�on and is located within a well-regarded explora�on/mining support jurisdic�on.
EMU has applica�ons and granted tenements over a package of highly prospec�ve explora�on tenements east of Esperance in Western Australia. The 1,560 square kilometre Condingup Rare Earth Project overlies saprolite, clay enriched rare earth soils, and covers the geologically significant Booanya granite suite. The project tenements are located directly over what EMU considers to be the last remaining vacant Booanya granite tenements in the region extending from Condingup to Balladonia, east of Esperance.
