New REE Carbonatite Targets Outlined at Lyons River Project
Highlights
27 Rare Earth Elements (REE) and carbonatite targets corresponding to a range of magnetic,
radiometric (thorium) and ASTER imagery response outlined at Dalaroo Metals Lyons River
Project.
Lyons River Project contains the Durlacher Super Suite and Halfway Gneiss covering an area
of over 700 km2 which host nearby Hastings’ Yangibana and Dreadnought’s REE deposits to
the north and Kingfisher Mining’s Mick Well REE discovery to the south.
Systematic geochemical sampling programs are well underway at Marloo River/View Hill REE
prospects and have begun at the newly identified REE carbonatite target areas.
Lithium potential pegmatite swarms of the Thirty Three Supersuite at Lyons River with high
LCT fertility extending across a 9km x 6km zone are being targeted in the current next phase
of exploration. Highly anomalous values of 114ppm lithium (Li), 1638ppm rubidium (Rb),
329ppm niobium (Nb), 116ppm tantalum (Ta), 182ppm tin (Sn) across a number of lithium
targets at Lyons River.
Dalaroo Metals Ltd (ASX: DAL, “Dalaroo” or “Company”) is pleased to announce that a detailed review
by consultant geophysicist of a range of datasets held and acquired, including detailed magnetics,
radiometrics (thorium) and ASTER, have outlined 27 targets with potential for Rare Earth Elements (REE)
and carbonatites in its Lyons River Project in the Gascoyne Province of Western Australia (Figures 1 and
5). Dalaroo has commenced its exploration field work for the 2023 field season and the planned field
work is anticipated to define drill targets and expected to be completed during the September 2023
quarter. It will comprise:
•
•
•
Geological reconnaissance and rock chip sampling of REE/carbonatite targets
Systematic soil geochemical program of target areas
Geophysical surveys
Dalaroo’s Managing Director, Harjinder Kehal, commented:
“We are excited to have delineated such a large number of new REE carbonatite targets over the easternhalf side of our Lyons River Project and looking forward to completing geological reconnaissance and
sampling of these high-quality integrated targets for subsequent drill-test follow-up” Mr Kehal said.
Technical Commentary
A detailed review has been completed by merging available high resolution magnetic and radiometric
data over the Lyons River Project and the greater Gascoyne Province in order to generate an updated
set of imagery to assist in the characterisation of known carbonatites along with a review of Geological
Survey Western Australia ASTER imagery.
A total of 27 target areas have been identified for their geophysical characteristics that are compatible
with carbonatite associated geology. These targets have been strongly recommended for groundtruthing and rock chip sampling to investigate REE mineralization potential (Figure 1).

Dalaroo’s Lyons River Project stratigraphy comprises approximately 700 km2 of the Durlacher Super
Suite and Halfway Gneiss, transected by major NW-trending shear zones including the Chalba Shear.
This same stratigraphy and comparable structural setting hosts significant REE deposits nearby to the
north, at the Hastings Technology Metals Yangibana and Dreadnought Resources Mangaroon projects,
and to the south at Kingfisher Mining’s Mick Well project (Figure 2).

Next Steps
Dalaroo’s 2023 Lyons River Project field work season has commenced, with geological reconnaissance
mapping of newly-defined carbonatite-targets currently underway.
REE Potential
Systematic geochemical sampling programs to begin at the newly identified REE carbonatite target
areas. Exploration programs planned for the 2023 field season will also include completion of the
systematic soil geochemical programs at View Hill and extension soil geochemical programs at Marloo
River prospect where a zone of REE soil/rock anomalism covering an area of 1.5km by 0.5km has been
delineated with peak value of 0.89% TREO (Figure 3). Positive outcomes of these programs will guide
first-pass drill testing of Marloo River targets during the second half of 2023. (ASX:DAL – See ASX
Announcement from 4 April 2023).

Lithium Potential
In the View Hill pegmatite zone, regional scale north-south oriented 100m-spaced soil sampling
transects are assessing geochemical trends in LCT fertility and rare metal/Li prospectivity across the large
9 km x 6 km area. Constraining potential geochemical zonation across the pegmatite swarm can aid in
vectoring towards rare metal mineralized pegmatite domains.
Pegmatites in the adjacent Yinnetharra district form part of the intrusive Thirty Three Supersuite (“TTS”),
which comprises granite, granitic pegmatites (microcline-muscovite-tourmaline), and rare-metal
pegmatites in high-grade amphibolite facies metamorphic domains. Recent field mapping during the
second half of 2022 confirmed that the granites and pegmatites of the TTS have also intruded the host
stratigraphy of the Lyons River Project tenements (Figures 1 and 3).
Dalaroo’s lithium anomalous rock chip results targets are located approximately 21km south-west of
Delta Lithium’s Yinnetharra Lithium Project (Figure 3). The Yinnetharra Lithium Project has returned
significant drill intersections that included 20m @ 1.28% Li2O, 15m @ 1.28% Li2O and 55.6m @ 1.12%
Li2O (ASX: DLI -See ASX: Announcements from 3 April 2023 and 8 May 2023).
Selective reconnaissance rock chip sampling completed at View Hill of the pegmatites has demonstrated
whole rock geochemistry that is considered highly fertile for LCT-type pegmatites associated with Li
mineralization (Figure 3). Assays from the pegmatite swarm that extends across a 9km X 6km area have
returned highly anomalous values of 114ppm Li, 1638ppm Rb, 187ppm Nb and 182ppm Sn. Rock chip
sampling of pegmatites in other targeted pegmatite swarm areas, west of View Hill, has returned
significant Ta and Nb values of 116ppm and 329ppm respectively with anomalous Rb of 904ppm
(ASX:DAL – See ASX Announcement from 1 December 2022).
