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 atPilgangoora. 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 andGalaxy 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 withseveral 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 forIOCG±U deposits (iron-oxide-copper-gold-uranium), Cu-Ni-Co deposits (Nebo Babel style), preciousmetal 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 recentlyopened up for mineral exploration. The area and near surrounds host major mineral depositsincluding Olympic Dam, Carrapateena and Prominent Hill.

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.

Musgrave Alcurra-Tieyon Project

WEX has identified highly prospective areas based on historic geophysical and geochemical data published on the South Australian Resources Information Gateway (SARIG). Strong evidence of extensive Giles Complex ultramafic intrusive rocks with excellent potential for Ni, Cr, Cu, Co, Au and PGE deposits.

Musgrave Alcurra-Tieyon Project – prospective areas

As with much of the project area there is strong remanent magnetism at Cavanagh together with high assay values of Ni, Cr, Co, Cu and Pd recorded in a 28m RC drill hole 167831 published in SARIG.

• The reverse dipole as observed in the TMI was investigated by CRAE around 1995• Using 3D Inversion methods and VRMI filters WEX has modelled the magnetically susceptible body that causes

the dipole

• First noted by RTZ in 1997 after flying four experimental EM lines.

• Interpreted as layered ultramafic complex with potential for Ni, Cu and PGEs.

• Magnetic 3D inversion modelling allowing for remanence predicts a susceptible body at ~100m and several hundred metres in length

• Plan to follow up with more EM to delineate conductor and test with DDH.

• Extensive area of remanently magnetised rock which when removed reveals large region of high magnetic susceptibility

• Sulphides as chalcopyrite, pyrite, and pentlandite, occur within the mylonitised (re-crystalised) rock

• Larger sulphide blebs up to 0.6 mm occur in less deformed areas and consist of variable proportions of pyrite, pyrrhotite, chalcopyrite and pentlandite

• Deeper intercepts were partly re-crystalised, highly magnetic with sulphides consistent with Giles Complex

• Sulphides as chalcopyrite, pyrite, and pentlandite, occur within the mylonitised(re-crystalised) rock

• 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
