Wudinna Project Update
Re-Analysis of 2020 Drilling Confirms More Rare Earth Mineralisation Above
Gold Resources
Validates Potential for Rapid Expansion of Defined Rare Earth Mineralisation
Footprint
Cobra, a gold and rare earth exploration company focused on the Wudinna Gold
Project in South Australia, announces results from the re-analysis of 15
drillholes from Reverse Circulation ("RC") drilling completed in 2020 at Baggy
Green, Barns, and White Tank. Drillholes were re-analysed for lanthanides
following the Company's recent rare earth discovery at Clarke.
· Rare Earth Elements ("REE") have been intersected in all drillholes
confirming the potential for desirable clay hosted, Ion Adsorption ("IAC")
mineralisation within the saprolite horizon above and proximal to existing
gold resources at Baggy Green, Barns, and White Tank
· At a 350 ppm Total Rare Earth Oxide ("TREO") cut-off, all holes
resulted in significant intersections where the average grade is 623 ppm TREO
over an average true width intersection of 11m. Spatially, this demonstrates
the significant expansion potential of thick zones of REE mineralisation
· At a 500 ppm TREO cut-off, 13 (or 81%) of the holes returned multiple
significant intersections per hole, where the average grade is 748 ppm TREO
over an average true width intersection of 5.3m. Discrete, higher-grade zones
exist within intersections, demonstrating the potential to identify zones of
higher grade
· The quantity of high-value magnet rare earths is consistent with
results from the previously reported Clarke discovery, with the combined
average neodymium/praseodymium quantity being 20.2% of the TREO, and
dysprosium equating to 1.8% of the TREO
· The results demonstrate the potential to significantly increase the
defined footprint of Rare Earth Mineralisation through the re-analysis of
historical drillholes. Further results from 38 holes at Clarke, and a further
66 holes from Baggy Green, are expected this month
Rupert Verco, CEO of Cobra, commented:
"These results are defining a unique, high-value mineral occurrence. To have
potentially Ionic Adsorption Clay hosted Rare Earth Mineralisation overlaying
a defined JORC gold mineral resource of 211,000 ounces is a compelling value
addition.
The critical nature of magnet rare earths to global decarbonisation, coupled
with the long-term fiscal stability of gold, enables Cobra to define a
globally unique mineral inventory in a stable and world-class mining
jurisdiction, that puts us in a very enviable position.
We are poised to capitalise on this transformational discovery by expanding
the footprint of rare earth mineralisation through low-cost re-analysis,
whilst metallurgical leachability test work is progressing.
The team are working towards a fully funded field programme that is designed
to further expand the rare earth footprint, add additional ounces to the
existing gold resource, and test potentially significant IOCG targets. It's an
exciting time for Cobra."
Summary of Results:
· REE mineralisation has now been intersected over 2.4 km from Baggy
Green to Clarke - outstanding re-analyses shall define the mineralisation
continuity
· The highest grade 1m downhole intersect was located at the White Tank
gold resource, where CBRC0040 intersected 1m at 1,931 ppm TREO from just 13m,
warranting further re-analysis of historically drilled holes from White Tank
and Barns
· The concentration of radioactive elements is low, a benefit of IAC
style REE mineralisation, with the average intersection concentrations of
thorium and uranium being 21 ppm and 5.9 ppm respectively
· Results demonstrate the regional potential for saprolite hosted rare
earths
Intersections from drillholes over and proximal to the Baggy Green
94,000-ounce gold resource include:
· CBRC0005 intersected a true width of 16.9m at 738 ppm TREO from
16.9m, including 5.6m at 1,105 ppm TREO from 19.7m
· CBRC0020 intersected 16.9m at 724 ppm TREO from 32.9m, including 9.4m
at 881 ppm TREO from 32.9m. This is above the previously reported gold
intersection of 1m at 3.73 g/t from 63m
· CBRC0022 intersected 16.9m at 557 ppm TREO from 18.8m, including 2.8
m at 1007 ppm TREO from 28.2m
· CBRC0003 intersected 17.9m at 562 ppm TREO from 12.2m, including 5.6m
at 859 ppm TREO from 22.6m
· CBRC0010 intersected 0.9m at 805 ppm TREO from 10.9m, and 20.8m at
586 ppm TREO from 16.3m, including 8.2m at 706 ppm TREO from 22.7m
· CBRC0016 intersected 9.5m at 611 ppm TREO from 24.2m, including 3.5m
at 1000 ppm TREO from 24.2m
· CBRC0017 intersected 14.8m at 598 ppm TREO from 29.5m, including 3.9m
at 984 ppm TREO from 31.5m
· CBRC0019 intersected 16.5m at 524 ppm TREO from 25.1m, including 2.6m
at 975 ppm TREO from 25.1m
Intersections from the two drillholes at the Barns 104,000-ounce gold resource
include:
· CBRC0028 intersected 0.9m at 825 ppm TREO from 11.2m above the
previously reported gold intersections of 1m at 1.01 g/t gold from 107m, and
1m at 1.2 g/t gold from 123m, as well as 2m at 2.7 g/t gold from 138m, and 14
m at 1.1 g/t gold from 147m
· CBRC0034 intersected 7.8m at 536 ppm TREO from 22.5m above the
previously reported gold intersection of 1m at 3.73 g/t gold from 163m
A single hole proximal to the 13,000-ounce gold resource at White Tank:
· CBRC0040 intersected 1.7m at 1,217 ppm TREO from 10.4m, and 8.7m at
460 ppm TREO from 29.4m
(1)Rare earth results reported as calculated true width intersects
(2)Gold results reported as downhole intersects
These results validate the Company's approach to drillhole re-analysis.
Further holes from Barns and White Tank are being identified and submitted for
re-analysis in the next phase which is underway.

About Cobra
Cobra's Wudinna Project is located in the Gawler Craton which is home to some
of the largest IOCG discoveries in Australia including Olympic Dam, as well as
Prominent Hill and Carrapateena. Cobra's Wudinna tenements contain extensive
orogenic gold mineralisation and are characterised by potentially
open-pitable, high-grade gold intersections, with ready access to nearby
infrastructure. Recent drilling has discovered Rare Earth Mineralisation
proximal to and above gold mineralisation. The grades, style of mineralogy and
intercept widths are highly desirable. In addition, Cobra has over 22 orogenic
gold prospects, with grades of between 16 g/t up to 37.4 g/t gold outside of
the current 211,000 oz JORC Mineral Resource Estimate, as well as one
copper-gold prospect, and five IOCG targets.

Discussion
In February this year, Cobra announced it had identified REE mineralisation
coincident with intersected gold mineralisation at the Clarke prospect which
lies 1.75 km North of the Baggy Green deposit that forms part of the Wudinna
Project's 211,000 oz Mineral Resource Estimate.
17 drillholes from the Company's 2020 resource extensional drilling programme
were selected for the re-analysis of lanthanide elements as a first pass to
determine the potential occurrence of REE mineralisation proximal to the camp
scale gold occurrences. All 15 holes reported (results for two holes remains
outstanding) have intersected REE mineralisation within the kaolin and
smectite clays that occur within the saprolite horizon, confirming the REE
occurrence extends to all defined gold occurrences that contribute to the
Wudinna Project's Mineral Resource Estimate.
Re-analysis of a further 38 holes from Clarke and 66 holes from Baggy Green is
currently underway to determine both the continuity and lateral extent of REE
mineralisation. Once these holes are received, over 4.2 km(2) will have been
analysed for REE mineralisation.
Next Steps
Further pulp samples retained from historic drilling at Barns and White Tank
will be selected for lanthanide re-analysis to determine the extent of REE
mineralisation at these locations.
Work is underway to define catalysts of REE enrichment of basement granites
and the secondary mechanisms that promote Ion Adsorption within the saprolite
lithology. Work to date supports associations to the Hiltaba deformation event
that is coeval the project's gold mineralisation.
Additional pulp samples from historic drillholes across several regional
targets are in the process of being identified and recovered for re-analysis.
21 REE samples from the Clarke 2021 drill programme are currently being tested
by the Australian Nuclear Science and Technology Organisation ("ANSTO") to
determine the metallurgical recovery of REEs through standard desorption
conditions. Once these results are received and reported, further testing will
be devised to optimise REE recoveries. The Company is in discussion with
several academic and technical teams to devise the best option for
progression.
Both Rotary Air Blast ("RAB") and RC drilling programmes are being designed
and the appropriate regulatory approvals are being sought to:
· Test extensions to gold and REE mineralisation at Clarke
· Drill test priority gold and REE targets
· Test resource extension targets
· Maiden drill test IOCG targets
· Contribute to a gold resource update, and enable a maiden REE
resource estimation
