Wudinna Project Update
Northern Drillholes at Clarke Intercept Additional Gold
Mineralisation
Additional Rare Earth Interceptions Directly Above Gold
Zones
Cobra, a gold exploration company focused on the Wudinna Gold
Project in South Australia, announces additional results from the
Company's recent 14-hole phase of Reverse Circulation ("RC")
drilling on the Clarke prospect. The Company is pleased to
report:
-- Further gold mineralisation has been intercepted within the
northern drill transect confirming the potential for a significant
gold mineral system at Clarke
-- Additional Rare Earth Elements ("REE") have been intercepted
above and proximal to gold interceptions. The Board considers the
discovery of critical REEs overlaying gold mineralisation to be
significant, with grades and intercept widths (summarised further
below) comparable to other rare earth projects of considerable
market value. This discovery now exposes Cobra to multiple high
value commodities
Fire assay results for gold have now been received for all holes
in the recent phase of drilling on the Clarke prospect,
multi-element and rare earth results are outstanding for a single
hole.
Rupert Verco, CEO of Cobra, commented:
"The results of the programme have demonstrated that the gold
system at Clarke is considerable in size, open to the north and
continues to present as a compelling target to add further ounces
to the existing Mineral Resource Estimate.
The rare earth discovery is also proving to be significant. The
occurrence of rare earths above defined gold mineralisation makes
the discovery unique when compared to other rare earth projects. We
have work to do to define the extent of this discovery and to
understand its potential to contribute to future project economics,
but undoubtedly this has added a new and very interesting dimension
to Cobra's potential.
There is a growing demand for magnet rare earths and an upward
forecast in pricing. A vertically associated gold and clay hosted
rare earth deposit offers shareholders exposure to multiple high
value and high demand commodities in close spatial proximity. We
look forward to growing a mineral resource that places Cobra in an
exclusive position within the mineral resource sector.
We are in the process of interpreting results and finalising our
planned 2022 work programme that will focus on increasing our
current gold resource, increasing the footprint of rare earth
mineralisation, and drill testing our IOCG targets."
A presentation of results from the 2021 drilling programme of
the Clarke prospect with management commentary is available to view

Highlights:
-- CBRC0050 intercepted 33m at 1.03 g/t gold from 65m, including 9m at 2.09 g/t gold from 65m(1)
-- Gold mineralisation has now been intercepted over 400m of
strike at Clarke with mineralisation open to the northwest of
CBRC0050
-- All holes intercepted rare earth mineralisation within the saprolite zone, where:
o The average true width of mineralisation is 18.7m and the
average Total Rare Earth Oxides ("TREO") is 597 ppm(2)
o High-grade intervals exist within the intercepts, where
drillhole CBRC0044 intercepted a true width of 9.4m at 1,030 ppm
TREO, CBRC0043 intercepted a true width of 4.7m at 1,160 ppm TREO
and CBRC0054 intercepted 6m at 1,446 ppm TREO
o The highest 1m intercept grade was 9,024 ppm TREO in CBRC0048
o Intercepts are enriched in high value rare earths where
neodymium/ praseodymium equate to 21.5% of the TREO and dysprosium
equates to 2.2%
-- Rare earth mineralisation intercepts are low in uranium (6
ppm average) and thorium (28 ppm average), a
favourable attribute of Ion Adsorbed Clay ("IAC") rare earth deposits
-- Results support the likelihood of rare earths overlaying gold
mineralisation at Barns and Baggy Green as well
-- Preliminary results from X-ray diffraction ("XRD") performed
by the Commonwealth Scientific and Industrial Research Organisation
("CSIRO") demonstrates that mineralisation is supportive of REEs
being adsorbed to clay mineralogy
The discovery of critical REEs overlaying gold mineralisation at
Clarke is significant, with grades and intercept widths comparable
to other IAC hosted rare earth projects of considerable market
value
-- Rare earth mineralisation is open to the north, south, east, and west of current drilling
-- REE intercepts confirmed above previously reported gold intercepts(3) , including:
o CBRC0042 intercepted 8.2m at 561 ppm TREO from 38.1m below

gold from 83m, including 5m at 2.62 g/t gold from 95m
o CBRC0043 intercepted 19.7m at 569 ppm TREO from 31m below
surface, including 4.7m at 1,160 ppm TREO from 38.5m below surface.
This is in association with the 96m at 0.55 g/t gold from 30m,
including 20m at 1.5 g/t gold from 88m
o CBRC0044 intercepted 19.7m at 717 ppm TREO from 31m, including 9.4m at 1030 ppm TREO from 33m
o CBRC0050 intercepted 4.7m at 380 ppm TREO from 15m and 3.8m at
456 ppm TREO from 48m below surface. This is above the 33m at 1.03
g/t gold from 65m, including 9m at 2.09 g/t
-- Additional rare earth results proximal to gold mineralisation at Clarke include:
o CBRC0046 intercepted 40.4m at 669 ppm TREO from 19.7m,
including 14.1m at 852 ppm TREO from 19.7m and 9.4m at 830 ppm TREO
from 47.9m

Further information on the Clarke drilling programme
The Clarke gold and REE prospect is located 1.75 km north of the
94,000 oz Baggy Green deposit that forms part of the Wudinna
Project's 211,000 oz Mineral Resource Estimate. In Cobra Resources'
maiden 2020 drilling programme, drilling intercepted 31m at 3.06
g/t to the north of previously intercepted gold mineralisation at
the Clarke prospect.
Follow-up pathfinder drilling in 2021 defined a zone of
anomalous gold and associated pathfinder elements across a 1.1 km
zone at Clarke. In November 2021, the Company completed a 14-hole
(2,144m) RC programme that was designed to test the extent of the
anomaly and the northern continuity of previously defined gold
mineralisation.
Re-analysis of samples from drillhole CBRC0009 confirmed the
presence of elevated rare earths within the weathered kaolinised
clays that lie directly above intercepted gold mineralisation. This
confirmed the requirement to perform additional rare earth analysis
within the weathered saprolite zone.

(1) Drilled in 2020, re-analysed for REEs and reported in Dec
2021
Results of the programme demonstrate:
-- The strike of gold mineralisation at Clarke has been doubled,
where the extent of mineralisation now exceeds 400m
-- Mineralisation is open to the northeast of drillhole CBRC0050
that intersected 33m at 1.03 g/t
-- The depth of gold mineralisation remains untested and is open with depth
-- The discontinuity of mineralisation across the central
transect is interpreted to be attributed to a late-stage E-W fault.
The presence of which has been supported by several geological
indicators (refer to figure 1)
-- HyLogger data demonstrates critical changes in mineralogical composition associated with gold mineralisation that are considered critical for future exploration targeting
-- Rare earth minerals are accumulated within the kaolinised
clays of the saprolite (weathered) horizon. The intercept widths
and grades are comparable to other IAC projects and are considered
economically beneficial to the Wudinna project
-- The Clarke drilling programme is the first that has
identified rare earth mineralisation, the potential extent of rare
earths is potentially significant due to:
o The margin settings of enriched Hiltaba Suite and Sleaford
Complex granites are present throughout the project's land
tenure
o The depth extent of basement weathering, where kaolinised
profiles of up to 60m present as highly favourable zones to host
IAC style rare earth mineralisation
-- Elevated rare earth grades have a spatial association to gold
mineralisation at Clarke and the saprolite weathering profile at
Clarke exhibits geological similarities to the saprolite horizons
at Baggy Green and Barns. Re-analysis of retained drillhole pulp
samples presents as a low-cost exploration opportunity to define
further rare earth mineralisation
The proximity of rare earths to gold mineralisation is unique,
the complementary nature of both forms of mineralisation has the
potential for favourable economics: there are currently no IAC rare
earth operating mines in Australia, and no IAC rare earth projects
with associated gold mineralisation
-- Rare earth mineralisation is open in all directions and the
continuity and consistency of rare earth mineralisation means that
there is a significant opportunity to increase the extent of the
current mineralisation footprint
Rare earth results remain outstanding for hole CBRC0055. These
results are expected within two weeks. Results have been delayed
due to the current Covid-19 situation in South Australia.

HyLogger Analysis
Preliminary results from the South Australian Department of
Mining HyLogger analysis of drill chips have defined key alteration
assemblages. Results demonstrate chemical changes within key
alteration mineral assemblages directly associated with gold
mineralisation that have previously been unidentified. This is
considered critical in understanding the nature of mineralisation
and will improve exploration targeting moving forward and enable
the development of robust geological models.
CSIRO Analysis
Preliminary XRD analyses from the CSIRO - Mineral Resources,
supports that a considerable portion of REOs are adsorbed to clay
particles. This is from XRD analyses of sieved samples >2 u m
(microns) and <2 u m, where:
o Phosphorus pentoxide concentrations remained equal in both
size fractions (a compounding XRD analysis demonstrating negligible
change in florencite and monazite concentrations)
o The concentration of REEs effectively doubled in the fine
(<2 um) fraction, indicating that REE bursary may be adsorbed to
clay mineralogy
Next Steps
Analysis of HyLogger data and multi-element chemistry is
underway to validate the structural interpretation of the gold
mineralisation at Clarke. Pending findings, the decision to
estimate a maiden gold mineral resource estimate at Clarke before
further drilling will be evaluated from the increased geological
understanding.
Further samples are at the CSIRO laboratories, Adelaide, to
increase the dataset and confirm the mineralogy of rare earths.
Once these results are received further testwork will commence to
define the metallurgical leachability.
Work is underway to identify samples from historic drillholes
for re-analysis that will focus on growing the footprint of rare
earth mineralisation across existing gold resources at Barns, White
Tank and Baggy Green.
Further detail regarding the Company's planned 2022 exploration
works programme will be made available in the coming weeks.
