Boland Re-Assay Results
Further demonstrating scale of ionic mineralisation amenable to ISR
Cobra (https://cobraplc.com/) (LSE: COBR)
(https://www.londonstockexchange.com/stock/COBR/cobra-resources-plc/company-page)
, an exploration company advancing a strategy to lower the cost of critical
rare earth production at its Wudinna Project in South Australia, is pleased to
announce re-assay results from a further 195 samples (17 drillholes) which
continue to support ionic rare earth mineralisation continuity and scalability
at the Boland discovery.
Metallurgical testing aimed at demonstrating the suitability for in situ
recovery ("ISR") mining - a low cost, low-disturbance method - is advancing
with full results expected in June 2024. The opportunity for Cobra is to
demonstrate Boland as the world's only ionic clay rare earth project amenable
to controlled ISR in a region which already utilises the ISR extraction method
at a number of operating mines. The Company aims to achieve this through
benchscale studies currently underway, followed by an infield pilot study.
Boland Re-Assay Results Highlights
· Scale - results extend the defined rare earth mineralisation
footprint to over 33 km(2), with mineralisation being open in multiple
directions along the palaeochannel, supporting the Company's interpretation
that lithologies hosting ionic mineralisation extend up to 139 km(2) of the
Narlaby system at the Boland prospect alone. Re-assay results have refined
targeting for upcoming resource focused drilling
· High grade intersections - 10 holes recorded 2m downhole composites
exceeding 1,000 ppm Total Rare Earth Oxide ("TREO"), where composites yield
heavy rare earth ("HREO") enrichment up to 40% of the TREO
· ISR - the unique geology at Boland enables ISR as a preferred mining
method. ISR is demonstrated by the uranium industry to be the lowest cost form
of mining with the lowest associated environmental risk. Bench-scale tests are
currently underway at ANSTO and, if initial AMSUL wash recoveries can be
emulated under ISR conditions, Boland will be demonstrated as globally unique,
being the only ionic clay project amenable to controlled ISR
· Further results pending - a further 674 samples from 25 drillholes
have been taken across the Yarranna SE Uranium prospect, where a >4km
uranium bearing rollfront has been defined by previous explorers. Samples are
being analysed for REEs and uranium and will inform native title and approval
requirements for follow-up drilling
Rupert Verco, CEO of Cobra, commented:
"Boland is shaping up to be a company-making project (See Appendix 1). Whilst
scale and ionic metallurgy are important, it is the amenability of Boland's
geology to ISR that has the ability to make it unique and commercially
competitive. The uranium industry has already demonstrated that ISR mining can
be effectively deployed in South Australian palaeochannel systems, where
capital, operational and environmental costs are materially reduced compared
to hard rock mines.
Through re-assaying (See Appendix 2), we have cost effectively defined scale
and de-risked planned resource focused drilling where we can target
demonstrated mineralisation and execute follow-up drilling to deliver a maiden
resource at Boland.
We are well positioned to capitalise on our first-in-market advantage. Results
from our initial bench-scale ISR trials are expected in June (See Appendix 3),
where subsequent tests will inform an infield pilot test, and we have already
installed the wellfield infrastructure which we aim to implement in 2025.
Through this strategy, we aim to demonstrate that via ISR, the cost of
extraction is materially lower and profitable at current rare earth market
prices."

About Cobra
In 2023, Cobra discovered a rare earth deposit with the potential to re-define
the cost of rare earth production. The highly scalable Boland ionic rare earth
discovery at Cobra's Wudinna Project in South Australia's Gawler Craton is
Australia's only rare earth project amenable for in situ recovery (ISR) mining
- a low cost, low disturbance method. Cobra is focused on de-risking the
investment value of the discovery by proving ISR as the preferred mining
method which would eliminate challenges associated with processing clays and
provide Cobra with the opportunity to define a low-cost pathway to production.
Cobra's Wudinna tenements also contain extensive orogenic gold mineralisation,
including a 279,000 Oz gold JORC Mineral Resource Estimate, characterised by
potentially open-pitable, high-grade gold intersections.

Appendix 1: Cobra's Boland Rare Earth Discovery
· Ionic clay hosted rare earths present as a low capital, low operating
cost source of heavy and magnet rare earth metals
· Processing of clay ores induces several operating challenges,
including productivity loss, material handling, dewatering, reagent use and
reclamation
· Ionic rare earth mineralisation at Boland exists in permeable geology
in an environment that permits ISR, thus bypassing the challenges associated
with processing of clay ores
· ISR is the preferred method of recovery used in the uranium industry,
where(1):
o Global ISR production accounted for ~60% of mined uranium in 2022
o Capital expenditure for ISR is 1-15% of conventional mines
o Operating costs of ISR is generally 30-40% lower than traditional mines
o Environmental impact and rehabilitation cost is significantly lower than
traditional mines
· South Australia is home to Australia's only three operating ISR
uranium mines and has a regulatory framework that supports ISR mining
· Bench-scale leach studies under ISR conditions are currently underway
at ANSTO, a first for ionic REE projects outside of China
· Cobra has installed a wellfield to rapidly advance the project
towards an infield pilot study
· Cobra aims to demonstrate that the cost of production at Boland can
be materially reduced via ISR, providing operating resilience to volatile rare
earth markets which has stalled the commencement of many rare earth projects
· Re-assaying of historic uranium focused drilling is being used to
confirm the scale of rare earth mineralisation. These results confirm the
presence of rare earth mineralisation over a strike of 12 km, where
mineralisation is open in most directions. Follow-up drilling will aim to
infill these results to support a maiden Mineral Resource Estimate ("MRE") at
Boland
