PART I. Introduction 1. Tenure Details EL9975 granted 03/06/2002 9 blocks for 6 year period EL9998 granted 03/06/2002 20 blocks for 6 year period EL23624 granted 24/02/2003 11 blocks* for 6 year period EL9975 and EL9998 have retained their original application area and an Application for Renewal (2 years) was lodged on 29th February 2008. * The current 11 blocks constituting EL23624 are the remnants of the original grant of 22 blocks. 2. Location The Renner Springs project area is located 60km northwest of the Bootu Creek manganese mining operation and 15km west of the Renner Springs roadhouse. Figure 1. Location Plan

3. Geology The Renner Springs project is located within the Namerinni Group in the Ashburton Province of the Tennant Creek Inlier. The favourable manganese bearing horizon is hosted principally by the Shillinglaw Formation, though minor flat lying manganese mineralisation may also underlie an interpreted Cretaceous cover sequence in the project area.

The most significant manganese outcrops occur in close proximity to the western boundary of EL9975 and EL9998 (see Figure 3). The manganese outcrop in EL9998 strikes north-south and appears to dip shallowly to the east while the manganese outcrop located in EL9975 strikes at approximately 330 (sub-parallel to Hunters Creek) and appears to dip shallowly to ENE. The outcrop described above has a distinct breccia/conglomerate texture with massive manganese replacement of the matrix supporting readily identifiable clasts of country rock. Recent drilling suggests that the outcrop is underlain by several, relatively narrow 1-2m shallow dipping manganese horizons (bedding parallel) and the surface outcrops may be enriched over time by the effects of a deflation lag. Other flat lying (horizontal) outcrops located in the central area of EL9998 rarely exceed a depth of a few metres in RAB drilling and appear to be largely supergene in nature. Historical trial pits were excavated by prospectors to the north of Hunter Creek in circa 1960 and are limited to a depth of around 1.5 metres. Figure 2.

PART II Previous Exploration Activity 4. Previous Exploration Activity 4.1 Bootu Creek Resources Pty Ltd – Reconnaissance Drilling A total of 133 RAB and RC drill holes have previously been completed on the project area for a total of 2,637 metres. All holes were collared on EL9975 or EL9998. The initial drill program focussed on the east and northeast dipping mineralisation located along the Western Contact located near the western margins of EL9975 and EL9998 (BH prefix). The second drill program concluded in June 2005 and was directed at testing flat lying manganese mineralisation located near the centre of EL9998 (RPH prefix). Detail of all drill collars is listed in Appendix 3. Table 1. Renner Springs – Selected Intersections from Previous Drilling

4.2 OM Manganese Ltd Bootu Creek Resource changed name to OM (Manganese) Ltd in January 2006. Exploration activity by OMM on EL9975, EL9998 and EL23624 since that date has included

• satellite-borne spectral study (ASTER), • geological field reconnaissance, and • petro-physical analysis of mineralised samples

4.2.1 Spectral Study OM Manganese commenced a satellite-borne ASTER spectral study over the area in an attempt to identify possible Mn mineralisation targets, Fe-rich zones, prospective stratigraphical units and contacts, and prospective structures. The Advanced Thermal Emission and Reflection Radiometer (ASTER) can be considered to be the geological successor to Landsat TM. The ASTER satellite is onboard one of NASA’s Earth Observing Satellite systems, Terra, which was launched in 1999. The ASTER instrument collects data in 14 bands together with one stereo, backward-looking band. The ASTER instrument consists of three separate instrument subsystems, with each subsystem operating in a different spectral region and having its own telescope(s): the visible and near infrared (VNIR), the SWIR, and the TIR. It has a mixture of spatial resolutions, ranging from 15 m in the visible part of the spectrum to 30 m in the SWIR, to 90 m in the TIR. Minerals of interest to the exploration of hydrothermal Mn and base-metals mineralisation within the Renner Springs Project area that can be identified in the SWIR region include: • Mg-OH minerals and carbonates — major components of lithological units

associated with mineralisation. Landsat TM cannot discriminate these minerals • alunite–pyrophyllite — significant because they can define areas of argillic

alteration. Landsat TM cannot discriminate these minerals • kaolin-group minerals — also significant because they are useful in helping to

define argillic alteration and in mapping regolith • illite–muscovite–smectite — common minerals in the surficial environment and

useful for mapping regolith. They are also associated with both phyllic and argillic alteration

One ASTER scene, collected on 20th September 2004, covering the entire extent of the Renner Springs Project area was sourced for OMM by Geoimage Pty Ltd, an imagery specialist consultancy based in WA. Product processing is detailed in Appendix 1. Overall results from the initial ASTER spectral study were very promising and have already made valuable contributions to the Renner Springs Project exploration efforts. Additional processing was subsequently completed by Resource Potentials in 2007 and is summarised in Appendix 2 of the 2007 Renner Springs Annual Report.

4.2.2 Geological Reconnaissance Field reconnaissance confirmed to project area was highly prospective and under-explored. Two mineralised styles were identified, both different in character from that mined at Bootu Creek. A total of 9 new manganese occurrences and extensions to existing mineralised zones were identified and indicated in red of the figure below (previous know outcrops shown in orange). Figure 3. Identified Manganese Outcrops in Renner Springs Project.

Results for rock chip samples collected for a physical properties study by Systems Exploration Pty Ltd are summarised in Appendix 2. 4.2.3 Physical Property Studies A total of 9 samples (3 from Renner Springs) were submitted for physicals property testing by Systems Exploration Pty Ltd prior to assist with the preparation of a airborne geophysical survey. The location of the samples and results of the study are outlined in the 2007 Renner Springs Annual Exploration Report.

PART III. Exploration Activity for year to May 2008 5. Current Exploration Activity Exploration activity on EL9975, EL9998 and EL23624 for the 12 months to 03/06/2008 included

• heritage clearance survey, • 875 line km helicopter borne SkyTEM geophysical survey (total survey 2,300

line km), and • Access and site preparation for a planned 2,000 metre RC drill program

originally outlined in the Renner Springs 2007 Mine Management Plan. and • Commencement of that RC drill program.

5.1 Heritage Clearance The initial Heritage Clearance Survey was conducted in May 2007 (and written up in June 2007) identified two significant sites located near the boundary EL9975 and EL9998, mid distance between the western and eastern manganese trends. The traditional owners were uncertain as to the lateral extent of that site and a follow up survey was requested at that time, though later deemed unnecessary by the consultant Anthropologist. The lateral extension of the above sites west along Hunter Creek potentially compromises access to the prime northern exploration target, located on the western mineralised trend in EL9975 (including the site of historic manganese mining activity during 1950/60). The report was eventually forwarded to OMM in September 2007 with an agreed modified access route skirting south around the sacred sites and with a restriction placed on grading of an access track within 100 metres of Hunter Creek. The later restriction will require further negotiation as the only sensible access route requires crossing Hunter Creek approximately 1 km west of the sacred sites. A subsequent request for full AAPA clearance of the Renner Springs Project area was submitted in May 2008. 5.2 SkyTEM Survey EL9975, EL9998 and EL23624 were covered as part of a project scale helicopter borne SkyTEM survey, conducted by Geoforce Pty Ltd, with approximately 38% or 875 line km of the combined 2,300 line km survey being flown over the 3 Licences. The survey was flown on 200m spaced east-west flight lines and in-filled to 100m spaced flight lines in areas of known mineralisation. The sensor height was located approximately 30m above ground level. The survey was modelled by Southern Geoscience and the resultant interpretation is being used to fine tune drill targets along the known manganese trends and to identify other potential manganese mineralisation.

5.3 Preparation for RC Drilling Several field days were required to peg the proposed drill sections prior to clearing. Approximately 40 kilometres of existing access tracks required repair to facilitate access by a heavy RC drill rig. The actual route of the access track was modified to avoid proximity to areas indentified in the initial Heritage survey and restricted to areas south of Hunters Creek until access across Hunters Creek can be negotiated.

Page 10: OM Manganese Ltd - geoscience.nt.gov.au · Part II Previous Exploration Activity . 4. Exploration Activity 4.1 Bootu Creek Resource Pty Ltd – Reconnaissance Drilling 4.2 OM Manganese

Clearing involved floating a D9 dozer and grader to the Renner Springs Project area and approximately 3 days for the repair of existing access tracks and clearing of proposed drill sections. 5.4 Commencement of RC Drilling Drilling commenced on the 1st of June and 606 metres (9 holes) had been completed by the anniversary date of 2nd June 2008, out of 2,579 metre (30 holes) completed in the first phase of the initial drill program completed on 9th June 2008. Details of drill logs, assay results and drill hole database will be included in the 2009 Renner Springs Annual Exploration Report. Assay results were not available at time of writing this report. The location of drill collars completed to 3rd June 2008 is listed in the following table. All drill collars listed below are located on EL9998. The second phase of the initial RC drill program has been delayed pending resolution of access issues to drill targets north of Hunter Creek. Table 2 Drill Collar Co-ordinates (MGA94)

The intent of the current RC drill sections is to test the number and thickness of manganese horizons (seams), dip and down-dip extent and strength of the mineralisation in order to assess resource potential of the deposits. The following figure displays the location of the current 30 RC hole drill program (red) relative to existing shallow RAB and RC holes (white).

PART IV Exploration Program for 2 years to May 2010 7. Proposed Exploration Program for 2 Year Extension Period. 7.1 Delineate Inferred Resource (Year 1) The first phase of the initial RC drill program was in progress at the commencement of 2008/2009 year (3rd June 2008) and a further 1,973 metres (21 holes) were completed by 9th June 2008. The second phase of the initial RC drill program will be to test the resource potential beneath the massive manganese outcropping to the north of Hunter Creek, once access issues are resolved via an AAPA clearance, and will involve at least 4 drill sections for around 1,200m of RC drilling. Following on from completion of the initial RC program, a 300m diamond drill program (6 x 50m holes) is proposed to test the metallurgical properties of the manganese mineralisation with particular reference to the upgrade potential by Heavy Media Separation. The Renner Springs mineralisation can not be assumed to have the same upgrade characteristics as Bootu Creek (given its geological variation) without bench testing. The Renner Springs mineralisation displays a dissolution breccia style characterised by a disseminated to massive manganese rich matrix supporting barren 2-10cm chert clasts. The breccias are hosted within the lower lithofacies of the Shillinglaw FM which are approximately 100M years younger than the Attack Creek FM which hosts the strata-bound Bootu Creek Manganese deposits. Subject to successful outcomes from the above metallurgical program, the plan is to proceed with an aggressive RC resource delineation program (4,000m) within the first year of the renewal period to define the extents of an inferred resource for the western mineralised zone. In parallel with the above delineation program, reconnaissance exploration will continue to search for and test other manganese deposits within the Renner Springs project area, including the central flat laying manganese outcrop located on EL9998 and EL23624. A high density aeromagnetic survey is being considered for coverage of both the Renner Springs and Helen Springs project areas. 7.2 Ore Reserve and Mine Plan (Year 2) The objective for Year 2 will be to determine the economic potential of the Renner Springs Project by upgrading the inferred resource delineated in Year 1 to Indicated Resource status, and to assess the economic potential for a stand alone or satellite manganese operation supported from the existing Bootu Creek operation. The amount of RC drilling required to upgrade the Inferred Resource is dependent on the actual size of the resource delineated, but has been assumed at 4,000m. An

Page 14: OM Manganese Ltd - geoscience.nt.gov.au · Part II Previous Exploration Activity . 4. Exploration Activity 4.1 Bootu Creek Resource Pty Ltd – Reconnaissance Drilling 4.2 OM Manganese

additional 300m of diamond drilling is likely to be required to refine the metallurgical model for potential processing routes. The above should provide sufficient detail to establish an ore reserve and mine plan. Assuming the outcomes of the above assessment are successful then OMM would commence a prefeasibility study to establish viability of a stand alone (or satellite operation) to mine and process manganese ore. Any additional deposits discovered by reconnaissance exploration on the licences during the first year of the renewal period would be drilled to inferred resource status in Year 2. 8.
