2 ABN OZ MINERALS QUARTERLY ACTIVITIES TO SEPTEMBER SAFETY AND ENVIRONMENT During the last quarter we suffered three tragic safety incidents. Two of our people died at work and one sustained serious head injuries. An electrical superintendent at Sepon was killed as a result of a lightning strike during preparatory works associated with installation of a new radio transmission tower. A supervisor at the new Prominent Hill borefield was killed when the light vehicle in which he was the driver and sole occupant rolled on an unsealed road between the borefield and the mine site. A boiler maker at the Century mine was seriously injured while working on a drill rig. Our thoughts are with the families of each of these members of the OZ team and we are providing as much support as possible. Thorough investigations have been conducted into these incidents to identify opportunities to improve our management systems and practices across the company. During the last quarter, there were four significant environment incidents reported by the group. Of those incidents, three resulted from discharges to water and one was a spill. These included: Water discharge concentrations of cadmium exceeded license conditions on two occasions, and on one occasion selenium, at Golden Grove, Western Australia. Water discharge concentrations of sulphate, nickel and manganese exceeded license conditions at Avebury, Tasmania. Lead concentrate was spilt when a road transport trailer tipped over near Century, Queensland. Actions were put in place to address the causes of these incidents. OPERATIONS SEPON COPPER Although the volume of material mined for the September quarter was lower due to heavy rainfalls impeding access to the copper pit during the wet season, volumes of copper ore treated and final copper production were the highest on record, exceeding first quarter 2008 s record production by 400 tonnes. There is a scheduled 7-day mill re-line that will occur in the fourth quarter but we anticipate meeting the full year production guidance of 60,000 to 65,000 tonnes. TABLE 1 QUARTERLY SEPON COPPER PRODUCTION & COST STATISTICS SEP QTR 08 PRODUCTION (STRIPPED TONNES) 17,546 47,919 TOTAL CASH COSTS US /LB SEPON GOLD Similarly to Sepon Copper, ore mined was adversely affected by heavy rainfalls and minor pit flooding. Ore milling and recovery rates were strong, enabling 22,190oz of gold to be produced for the period. Both the Houay Yeng and Phavat North mines have been opened. Mining volumes are expected to meet forecast in Q4 and production forecasts for the year remain at 85,000 to 95,000oz. TABLE 2 QUARTERLY SEPON GOLD PRODUCTION & COST STATISTICS PRODUCTION (GOLD* oz) 22,190 65,521 TOTAL CASH COSTS - US$/oz * PRODUCTION REPORTED IS GOLD POURED GOLDEN GROVE Mining and milling at Golden Grove was mostly focused on copper for the quarter. Consequently, zinc production was down for the quarter at 23,778t while we posted strong copper production of 6,692t. Negotiations with electricity provider Alinta restored electricity pricing to original contract rates, rather than higher spot rates, which had increased considerably due to the gas shortage that resulted from the Varanus Island pipeline explosion. OZ Minerals announced that, in the current pricing environment, it will reschedule production at Golden Grove, reducing zinc production and increasing copper production in Zinc output will be reduced by between 35% - 40% of planned production of 130, ,000t to 80,000 85,000t in OZ Minerals will simultaneously increase production of copper in concentrate by approximately 14,000t to between 35,000 40,000t for TABLE 3 QUARTERLY GOLDEN GROVE PRODUCTION & COST STATISTICS ZINC (TONNES) 23,778 80,075 COPPER (TONNES) 6,692 16,369 TOTAL CASH COSTS - US /LB CENTURY Zinc metal production for the quarter was strong due to higher than planned zinc feed grade and above plan production through the port dewatering facility. This was despite lower zinc recovery resulting from high feed blend variability. Resources will continue to focus on increasing zinc recovery performance, utilising the newly commissioned ball mill. Lead metal production was similarly strong due to higher than expected lead feed grade and above plan lead recovery. The Century pit operated at record high material movement levels and mining of ore from Stage 6 progressed to plan. Total material moved for Q3 was 28mt against the corresponding quarter the previous year of 29mt.

3 ROSEBERY While ore treated was 13% higher than for the comparative quarter, zinc in concentrate production for the September Quarter was down 5% on the previous quarter due to lower ore grades. Lead in concentrate production was 14% higher than the previous quarter and 19% higher than for the same period last year, reflecting higher ore treated and higher metal grades. Copper production was lower reflecting the lower metal grades. Raisebore pilot hole drilling for Stage 1 of the Northern Downcast Shaft to 650m was completed. TABLE 5 QUARTERLY ROSEBERY PRODUCTION & COST STATISTICS TOTAL CONTAINED METAL ZINC (TONNES) 21,139 63,582 LEAD (TONNES) 7,557 20,720 TOTAL CASH COSTS - US /LB AVEBURY Nickel concentrate production for the quarter was 4,796t and was above budget by 26%. Mill throughput and mine production were ahead of ramp-up schedule by 23% and 15% respectively. Commissioning and production ramp-up is ahead of plan with no major issues encountered. The site now has a full management team in place and there is a strong focus on improving internal controls particularly with contract management and purchasing. Diamond drilling is being accelerated to bring forward any opportunity to increase resources and reserves. Avebury is not yet operating at full production. Total cash costs may be expected to decline when this operation reaches full capacity. TABLE 6 QUARTERLY AVEBURY PRODUCTION & COST STATISTICS NICKEL (TONNES) SEP QTR TOTAL CASH COSTS US$/LB DEVELOPMENT PROMINENT HILL Construction continues at a steady rate and commissioning of a number of systems has commenced. As at 10 October, overall construction progress was 88% complete and the plant is on track for commissioning of ore in the final quarter. Load commissioning of the crusher was completed on the 18th October. Mains power from the newly constructed transmission line to Olympic Dam is on and development of the permanent water borefield and commissioning is underway. Key civil infrastructure, including the tailings dam and haul road to the rail siding, are essentially complete. The ball mill installation is complete with the SAG mill motors installed and lining of the shell is in progress. Production guidance for 2009 remains at 110,000t to 120,000t of copper and 75,000oz to 85,000oz of gold. SEPON COPPER EXPANSION Detailed engineering continues and is 84% complete. The flotation area thickener was commissioned and is online. During the third quarter orders were placed for the final electrical equipment and reticulation areas of the process plant, along with bulk piping materials. Bulk earthworks are complete and the main concrete contractor is making good progress and is 81% complete. The field erect tanks contractor is mobilised and erection of the seven new thickeners is in progress. The Steel Mechanical Piping (SMP) contractor commenced steelwork erection in the thickener and Electrowinning areas. The expansion is on schedule for completion in the fourth quarter of The second autoclave, which will improve the reliability and throughput capability of the plant, progressed with construction continuing with SMP works. The autoclave vessel was shipped and arrived onsite at the end of August as planned. Concrete works are 80% complete, all large vessels are placed on foundations, structural steel erection is 75% complete and pipework fabrication continues. Brick lining of the vessels commenced in September. The autoclave is on schedule for the completion of construction in the first quarter of SEPON INFRASTRUCTURE The new polishing plant (that treats excess water prior to discharge) commissioning was completed at the end of September as planned, and the plant is in operation. The design and construction of a second 115kV powerline to the Sepon mine site (includes upgrades of associated substations) continues, and is overall 21% complete. Line survey is complete, all long lead equipment has been ordered and tower steelwork is being delivered to site in preparation for erection in the dry season. Staged completion of sections of the transmission line are planned, with the project on schedule for completion in the third quarter of MARTABE Engineering activities continued to ramp up at the design office in Brisbane. Construction of the access road through to the plant site area commenced in mid-july and reached the plant site area at the end of September. Upgrading will continue during the current quarter. The tender for bulk earthworks and civil concrete was awarded. Contract execution with the prime contractor, Ausenco, was completed during the quarter. The mills, which were ordered in August 2007, remain on schedule for delivery later in DUGALD RIVER Feasibility Study work is on target for completion as planned by the end of this year. Drilling of the deposit for the Feasibility Study was completed during the quarter at a total of 47,200m and primary metallurgical test work is now completed. The resource model was updated and confirms our understanding of the Dugald River resource with discussions with potential customers progressing well. Environmental studies for the EIS are now complete. CANADA A substantial field work program to support the Izok Lake pre-feasibility study was completed during the summer field season in the Arctic. This included detailed mine, processing plant, road and port layout plans, flora and fauna mapping, engineering, tailings, water and other environment studies. 3

4 The pre-feasibility study is on track for completion by the end of REGIONAL EXPLORATION OZ Minerals intends to continue growing its business through a focussed and well resourced exploration effort. In order to ensure close alignment with company growth objectives, the OZ exploration group has recently completed a strategic review of its global portfolio and a number of projects and programs have been terminated while others have been added or strengthened. Priorities are on expanding the search for copper and nickel, maintaining a solid portfolio of zinc opportunities and establishing niche positions in bulk commodities and energy where OZ Minerals can add value through existing operating experience. Key objectives of the exploration programs are to maximise the intrinsic value held within our large land holdings around existing operations and to discover new resources capable of making a material difference to the OZ business. OZ will be targeting high quality projects on district scale land holdings within its key geographical focus areas of Australia, Asia and Canada. MINE DISTRICT EXPLORATION Sepon Copper Resource definition drilling recently completed at Phabang, Khanong and Thengkham North reported some outstanding results. At the Pha Bing deposit, an additional high-grade lode was also identified. Better intersections include: DEPOSIT FROM (M) INTERVAL (M) CU (%) AU (PPM) PHA BING KHANONG THENGKHAM NORTH Exploration drilling activities decreased with the onset of the wet season, although surface sampling programmes continued to generate new drill targets and advance existing prospects. Excellent primary copper-gold results continued to be returned from drilling at Thengkham East including 149.7m at 1.0% Cu, 0.5g/t Au and 312 ppm Mo from 66.3m and 72.3m at 1.3% Cu, 0.3g/t Au and 203ppm Mo from 57m. Mineralisation remains open in all directions and further drilling is required prior to the preparation of an initial resource estimate. Several new zones of primary copper mineralisation were also identified at the nearby Thengkham South deposit, with recent intersections including 42.5m at 1.3% Cu from 80.5m. Thick intervals of overlying chalcocite mineralisation have also been intersected in several holes including 63m at 1.6% Cu and 0.3g/t Au from 7 metres. Recent drilling in both areas has outlined several strike and depth extensions to mineralisation. These require further follow up drilling, and highlight the large tonnage, open pit potential of the Thengkham near mine deposits. Sepon Gold Numerous broad, high-grade results returned from resource definition drilling at the Houay Yeng oxide gold deposit confirmed a robust resource model. Better intersections include 26m at 23.6g/t Au from 62m and 37m at 13.1g/t Au from 60m. Recent exploration drilling at the Houay Bang primary gold target, 7km east of the Sepon mine returned several encouraging intersections over 250m of strike, including 20m at 3.6g/t g/t Au from 80m and 13m at 15.9g/t Au from 47m. The zone of interest remains open to the north-west and at depth and additional drilling is required to determine resource potential. At the Dao Leuk prospect, immediately west of Discovery Main pit, primary gold mineralisation was extended to over 600m of strike with better results including 8.2m at 8.0g/t Au from 193.4m, 20m at 3.6g/t g/t Au from 80m and 13m at 15.9g/t Au from 47m. An economic evaluation of the mineralisation is being completed prior to further drilling. Golden Grove Exploration continued on the southern leases during Q3 with two separate intersections of high grade zinc estimated visually. Dolerite intrusions have removed the target horizons in some holes. Ground magnetic surveys were completed over the Felix Prospect with data awaited. Prominent Hill Updated resource estimates reported significant year on year increases in the JORC-compliant resources for the Prominent Hill deposit (refer ASX release of 24 September 2008). The contained copper inventory increased by 35% to 2.5 million tonnes, the gold inventory by 100% to 7.4 million ounces and the silver inventory by 43% to 22.6 million ounces. Further outstanding drill results returned from drilling on the Western Copper-Gold Zone, approximately one kilometre west of the open pit, include 51m at 3.5% Cu, 0.3g/t Au from 306m and 64.9m at 2.5% Cu, 0.7g/t Au from 409m on section 4200E. These results are not included in the recent resource estimate. This recently discovered deposit remains open in several directions and further drilling is required to define the full extent and geometry of the mineralisation. Immediately east of the open pit, broad zones of lower grade copper extended previously intersected mineralisation. Better results include 71.5m at 0.7% Cu, 0.3g/t Au from 242m including 25m at 1.2% Cu and 0.7g/t Au. Martabe Exploration work continued on two porphyry copper-gold targets within the Kapur Gambir district, 30 km SE of the Martabe project. Geological mapping at the Aek Gotting prospect reported extensive alteration with rock samples returning up to 19.3% Cu, 3.1g/t Au and 65g/t Ag. An IP geophysical survey commenced at the Tani Hill prospect to help define drill targets. Drilling activities focused on further resource definition of the northern end of Barani deposit, and targeting extensions of the Purnama deposit to the north and at depth. Better results from Purnama include g/t Au and 48.5 Ag. Century Further high grade zinc mineralisation was intersected at the Watson's Lode prospect, 10km south of Century. A high grade zone containing around 10m of visual high grade zinc mineralisation within a broader 27 metre-wide mineralised interval was encountered. This suggests that the continuous strike length of the Watsons Lode vein style mineralisation is 4

5 now over 800 metres and significantly upgrades tonnage potential. Rosebery Follow up drilling to determine the potential associated with mineralisation recently reported at the Jupiter prospect, 5km south of the Rosebery Mine returned 6.3m at 2.4% Zn, 0.1% Pb, 6g/t Ag and 0.1g/t Au indicating continuity with mineralisation previously reported up dip. Deep drilling failed to intersect the mineralised horizon, but the system is open to the north and south. Avebury Drilling continued at the East Avebury and Viking Extended near mine targets, encountering extensions of the host ultramafic sequence and some sulphide mineralisation. All assays are pending. At the Melba Flats prospect, located northeast of the underground mine, drilling was ongoing. Canada - Nunavut An IP geophysical survey completed southwest of the Izok deposit outlined three priority targets for drill testing however no significant mineralisation was intersected. Two holes were completed on regional geophysical targets, one of which intersected trace chalcopyrite (copper sulphide). Assays are pending. Follow up ground EM geophysical surveys completed to follow up anomalies delineated by airborne survey, confirmed numerous high potential massive sulphide drill targets. These will be tested in the next field season. Rock samples collected from the Canoe Lake and North Cairo areas returned up to 11.2% Zn, 1.0% Pb and 4.0% Cu. Field mapping and surface sampling was completed at several prospect areas. Two claims were staked to the east of High Lake in areas identified to be prospective for intrusion-related mineralisation. Initial reconnaissance of the claim area has identified magnetite skarn rocks containing high grade copper-molybdenum mineralisation. Results are pending NEW DISCOVERY PROGRAM Thailand Nine of thirteen high priority tenement applications for iron ore in SE Thailand were granted. An additional four applications are still being processed at provincial level. Extensive ground magnetic and gravity surveys are in progress to delineate drill targets for testing in the coming quarter. Cambodia Recent studies indicate excellent potential for the discovery of a significant gold resource in the Okvau district and a number of additional properties are being evaluated and progressed as potential joint ventures. Initial sighter metallurgical test work confirms the mineralisation responds reasonably well to conventional processing with average recoveries of 65% reported from bottle roll tests completed on 187 samples. Exploration also continued on the Ou Anlong sedimentary copper project (88% OZ minerals) were field reconnaissance and soil sampling has identified three priority areas for drill testing. Seven interpreted mineralised zones, possibly 1-2m thick and potentially up 3km long have been delineated and three new areas requiring initial reconnaissance have also been defined. Indonesia portfolio of four porphyry and one nickel laterite target to drill status Americas Drilling was completed at the La Corazonada property in Mexico with eight holes drilled on the most accessible targets. While several mineralized zones were intersected the assay results received to date are disappointing. Under the Newgenco alliance for nickel in North America, thirteen areas were field checked to validate geology and confirm the presence of mineralisation. Within three areas evaluated, prospective mafic-ultramafic intrusions with disseminated or trace nickel and copper sulphides have been identified. Data from the field season is currently being compiled to determine which projects warrant further work. China Exploration focused the Xiaosongshan nickel sulphide project in Inner Mongolia Province. (Aoning joint venture - OZL 80%) An integrated IP-EM-MT ground geophysical survey outlined six high priority anomalies and rock samples collected from old pits and shafts have assayed above 1% Ni. A thorough environmental baseline survey has been completed and the project is ready for drill testing in the early 2009 field season. A second joint venture for nickel sulphides (OZL earning 80%) is being progressed with a State Government Bureau over the Chajianliang project in Jilin province where nickel is currently being mined from sheared parts of a larger intrusion and is adjacent to a large (250Kt contained nickel) deposit and lies within 20 kilometres of a major smelter. Further nickel JVs are in negotiation. MARKETING Base metal prices fell during the last month of the quarter due to the growing negative sentiment resulting from deteriorating global financial markets. The LME cash copper price averaged US$3.48/lb for the quarter, 9% lower than the previous quarter, and 0.4% [1c/lb] higher than the third quarter of Copper mine supply continued to fall below forecast, offsetting slower demand and supporting price levels. LME zinc prices fell 16% for the quarter, although LME stocks remained at historically low 155,000t, less then one week s global consumption. The gold price averaged $868/Oz for the quarter, down 3.1% from the previous record quarterly average. PROVISIONAL PRICING As at the end of the third quarter, Oz Minerals had provisionally priced the following payable metal.
