5. WEX Company Outline
Woomera Exploration Limited (“WEX”)
WEX is an unlisted Australian Exploration Company based in Adelaide, South Australia.
WEX has an extensive tenement portfolio:
• lithium tenement portfolio consisting of eight granted tenements and two tenement applications at
Pilgangoora. These tenements are proximal to Pilbara Minerals Limited’s Pilgangoora Lithium-
Tantalum Project which has an Indicated and Inferred Resource of 156.3Mt grading 1.25%Li2O and
Galaxy Lithium Australia Ltd’s Mt Cattlin project which has a Resource of 16.0Mt @ 1.08% Li2O.
Additionally WEX has several prospective lithium brine prospects throughout Western Australia.
• 4 tenements (1 Exploration Licence (“EL”) , 2 Subsequent Exploration Licence Applications (“SELA”)
and 1 Exploration Licence Application (“ELA”)) in the Musgrave Province of South Australia with
several drill-ready Cu-Ni-Co-PGE and Au-Ag targets that are under a binding HoA with OZ Minerals.
• 5 tenements (3 SELAs and 2 ELAs) in the Gawler Craton in South Australia that are prospective for
IOCG±U deposits (iron-oxide-copper-gold-uranium), Cu-Ni-Co deposits (Nebo Babel style), precious
metal deposits and rare earth mineral deposits
• Experienced Board and Management
Much of WEX’s South Australian ground has historically fallen under the Woomera Prohibited Area –
a huge area of South Australia quarantined for military purposes for over fifty years and only recently
opened up for mineral exploration. The area and near surrounds host major mineral deposits
including Olympic Dam, Carrapateena and Prominent Hill. 5

15. Musgrave Alcurra-Tieyon Project OZ Minerals HoA
On 12 September 2017, WEX entered into a binding heads of agreement with OZ Exploration Pty
Ltd (ACN 137 626 914) (OZ Exploration) (a wholly owned subsidiary of ASX listed OZ Minerals
Limited (ASX:OZL)) covering WEX’s granted tenements and tenement applications tenements in
the Musgrave Province in South Australia. OZ Minerals HOA is conditional on the execution of a
Native Title Mining Agreement (NTMA) with the Tjayiwara Unmuru.
The key terms of the OZ Minerals HOA are as follows:
• Stage 1 Commitment – within 12 months after signing a NTMA , OZ to fund exploration which
will be managed by WEX and will consist of detailed ground EM and the drilling of 3,850m RC
drilling of seven of the 12 targets identified thus far.
• Stage 2 Commitment – OZ Exploration may elect to fund $2,500,000 of exploration expenditure
(inclusive of the Stage 1 Commitment expenditure) within 18 months. When OZ Exploration has
met its Stage 2 Commitment, OZ Exploration entitled to a 51% interest in the Musgrave
Tenements. On Oz Exploration earning a 51% interest in the Musgrave, a joint venture will come
into effect with the initial joint venture interest being: OZ Exploration 51% and WEX 49%;
• Stage 3 Commitment - Within 60 days of the commencement of the joint venture, OZ
Exploration may elect to earn a further 24% interest in the Musgrave Tenements by spending a
further $5,000,0000 on exploration within 24 months of the commencement of the joint
venture. Upon meeting its Stage 3 Commitment, OZ Exploration will become entitled to hold a
75% interest in the Musgrave Tenements and the parties must execute all documents required
under the South Australian Mining Act 1971 (SA) to effect such outcome.

• Deeper intercepts were partly re-crystalised, highly magnetic with sulphides
consistent with Giles Complex
• Sulphides as chalcopyrite, pyrite, and pentlandite, occur within the mylonitised

• Larger sulphide blebs up to 0.6 mm occur in less deformed areas and consist of
variable proportions of pyrite, pyrrhotite, chalcopyrite and pentlandite
• High grade metamorphic phase
• This remanent zone covers a large area of over 70 Sq. Kms. and extends further to
the West of the GSWA magnetic data that has been used to identify the zone. If
sulphide accumulation has occurred it is likely to be around the edges of the
ultramafic zone and this is consistent with the observations from TIE RC 89.
• A combination of airborne EM, surface geochemical sampling and RC drilling will
be required to identify the extent of mineralisation in this zone
