Exploration History OZ MINERALS • PAGE 4 EXPLORATION HISTORY

• 1961: Delhi explored the Mt Woods area (approx 50 kilometres to the northwest) for iron ore. Shallow drill holes intersected iron rich mafic units and magnetic granulites.

• 1975: Olympic Dam discovery. OD Exploration Model: African Copper Belt type of sediment hosted syngenetic copper deposit – basement highs (magnetic and gravity highs).

• 1978: Newmont and Kennecott: Explored for Olympic Dam-type mineralisation.

• 1979-1981: Australian Selection and Aquitaine carried out exploration for Olympic Dam style mineralisation in various localities within the Mt Woods area.

• True nature of OD mineralisation poorly understood at his time.

OZ MINERALS • PAGE 5 Exploration History EXPLORATION HISTORY

• 1986-1989: CRAE carry out drilling in White Hill area. • Manxman Prospect: Hole DD88EN43 intersects 287 metres at 0.23% copper + anomalous Au, U and REE. • First indication of large iron oxide-rich breccia and replacement bodies, • 13 years after the discovery of OD.

OZ MINERALS • PAGE 6 Exploration History EXPLORATION HISTORY

• 1987: Metals Exploration Limited secures current leases east of the White Hill area in November – containing PH. Ground mag reveals Uranus magnetic anomaly. Burmine JV and drill 90URANRC1; 4m @ 0.2% Cu and 0.09g/t Au.

• “Gawler Range Volcanics” + magnetite + chalcopyrite discovered at Neptune prospect.

• 1991-2000: Normandy. Primary target was Joes Dam – magnetite breccias + ~0.1% Cu.

• 1993: NOREX drills many other prospects, including one hole at Uranus Prospect: Hole 93DD10 intersects 92m @ 0.12%Cu.

Minotaur Resources (MNR) floats, with Alliance backing from Billiton. World-class base metal deposit search. Target deposits are IOCGs and BHTs.

• High IOCG prospectivity of Mount Woods Inlier indicated to Minotaur by:

• High magnetic relief – Fe-oxides • Presence of known mineralisation and alteration systems; anomalism of REE, F, Ba, Cu and Au, • Na, K and Si alteration halos, • Evidence of high structural levels (i.e. GRV), • Various mafic to felsic intrusive suites & major NE and NW structures • Presence of mantle derived mafic rocks and related Hiltaba aged granites, 1580Ma.

• Minotaur approaches Normandy.

• 2000: Minotaur-Billiton Alliance. Farm-in, Minotaur as operator. 25 years after the discovery of OD

OZ MINERALS • PAGE 9 Discovery DISCOVERY OF PROMINENT HILL

• Barbara Anderson’s systematic data review. Five priority targets identified: 1. Blaze 2. Neptune 3. Uranus 4. Scorch 5. Balta Baltana

• Minotaur select six targets for 3D inversion modeling and drill testing: 1. Armstrong North 2. Blaze 3. Neptune 4. Uranus 5. Peculiar Knob North 6. Manxman B

• No new gravity data obtained: All data used was available to the previous explorer.

OZ MINERALS • PAGE 10 Discovery DISCOVERY OF PROMINENT HILL

• Wayne Petit and Chris Moore: 3D inversion ArmstrongBlaze North modeling at six prospect NeptuneUranus areas.

• Uranus model defined a large dense mass ~0.5gcm-3 > background.

• Heritage clearance obtained

• JV agrees to drill all six priority targets. Uranus is the forth to be drilled.

OZ MINERALS • PAGE 12 DISCOVERY OF PROMINENT HILL

• Burmine (1990): Uranus magnetic anomaly was drill tested, returning 4 metres at 0.2% Cu and 0.09 g/t Au, and 4 metres at 0.24% Cu and 0.04 g/t Au in magnetite skarn. Missed PH by a few hundred metres! In 1993 Uranus was revisited by Normandy. Hole 93DD10 also intersected magnetite skarn assemblages - 92 metres at 0.11% Cu. Late-stage carbonate-fluorite-haematite-sulfide veining noted in core. Missed PH by a few hundred metres!

• High-grade copper-gold mineralization at Prominent Hill was discovered in October 2001 through drill testing of a high frequency, non-magnetic portion of gravity anomaly. Results of URAN1 included; 20 metres @ 3.0g/t Au, 107 metres @ 1.9% Cu and 0.65g/t Au and, deeper, 152 metres @ 1.1% Cu and 0.6g/t Au.

• Infill gravity (contours – 2nd horizontal derivative) Drilling February to July, 2002 • Ground Magnetics (image). • Downhole IP and Dipole - dipole IP. Strong IP anomaly coincides with peak of gravity anomaly – not magnetic anomaly. • 14 diamond drill holes. First follow up hole targeted peak of IP/gravity - barren. DP 003: 30m @ 2.72%Cu, 0.45g/tAu. DP 005: 209m @ 1.54%Cu, 0.93g/tAu. •High-grade Cu mineralization confined to area adjacent to & immediately south of the magnetic anomaly. • ‘Gold-only’ mineralization identified.

•Airborne gravity gradient (AGG) and current ground gravity comparison;  Greatly improved detail defining new targets and important structures.  AGG survey flown in 8 weeks, equivalent ground data requires 2‐3 years to collect.

 1st vertical derivative (1VD) of ground gravity (~800m line spacing). ‐ Airborne gravity gradient (AGG) data (200m line spacing).
