Four Joint Venture programs targeting uranium, IOCG and orogenic gold targets are underway. InterMet continues to acquire prospective ground on the Gawler Craton with two new ELA’s totalling 1,051Km2 , targeting IOCG, Archaean base metals, Challenger style gold and unconformityrelated uranium targets. Highlights • Drill hole RD-DD2 was completed on the Lake Gilles Project Red Dam prospect, intersecting a magnetite-rich syenite with a 32 m zone of moderately intense quartz veining and alteration. The rocks in this hole show evidence that a significant hydrothermal system exists within the Lake Gilles project area and InterMet will commence drilling of the untested Salt Creek and Lake Edge gravity anomalies in February. Drilling of the Red Dam prospect failed to intersect an interpreted IOCG system with no significant results returned. InterMet is undertaking petrophysical measurements (density, magnetic susceptibility) of the drill core to ascertain the source of the gravity anomaly. • The first stage of the PACE funded Coulta drilling program was completed. Low level copper, zinc and cobalt values were encountered in drill hole COU006 and anomalous silver was in COU003. Followup drilling is planned to commence on January 29, 2007 with drilling to be completed by early to mid- February. • InterMet has applied for 2 new ELA’s. 1. Garford North (ELA 683/06) – located on northern Gawler Craton within Christie Domain which hosts the Challenger Gold Deposit. ELA 683/06 is prospective for gold mineralization similar to Challenger. 2. Mount Wedge (ELA 690/06) – adjoins Cocata Project and is prospective for unconformity-related uranium at the base of the Mesoproterozoic Blue Range Beds and Archaean hosted lead-zinc and gold mineralisation within interpreted Archaean basement rocks. • InterMet has moved Office to Unit1 22 Maple Street Forestville.
- 3 - InterMet Resources Limited Lake Gilles Project (EL 3466 and 3467, ELA 537/06 – InterMet 100%, Mega Uranium earning 80% in unconformity related uranium on EL 3467.) The project area is prospective for Olympic Dam Cu-Au-U, Broken Hill Style base metal, Orogenic Gold and Unconformity-related uranium. IOCG Exploration Hole RD-DD2 was a vertical hole collared at 685000E 6366500N on the Red Dam prospect of InterMet’s Lake Gilles tenement (EL3466). It was pre-collared to a depth of 45 m then drilled with NQ2 diamond core to a maximum depth of 470.5m, intersecting mainly massive, magnetite rich, porphrytic syenite with occasional bands of calc silicate alteration. The drill hole includes a zone of intense shearing, quartz veining and alteration from 408.0 m to 440.0 m The upper portion of RD-DD2 intersected massive, extremely corse grained, magnetiterich porphrytic syenite that contained occasional bands of sulphide-rich calc silicate alteration. These bands of alteration ranged in thickness from a few centimetres thick up to half a metre in places and contained mainly pyrite with some minor asenopyrite. The zone from 408 to 423m consists of a sheared, chloritised rock (in parts) with intense centimetre thick quartz and quartz carbonate veining parallel or sub parallel to the core axis. This zone contains some disseminated pyrite in both groundmass and in the quartz/quartz carbonate veins. From 423m to 440m, the core consists of intensely brecciated and altered quartz-feldspar syenite. There is evidence of partial re-melting and multiple phases of fluid flow through the rock. Sections of the core contain minor to moderate amounts of sulphide, mostly in the form of pyrite as well as a dark mineral along the vein edges, samples of which have been submitted for petrology. Assay results from selected bits of drill core are only slightly anomalous in copper and zinc with no significant results returned. .InterMet is currently undertaking petrophysical measurements (density and magnetic susceptibility) of the core to remodel the remaining holes at Red Dam. The drilling failed to adequately resolve the source of the major gravity feature. The presence of zones of calc-silicate alteration and chloritic alteration, zone of intense brecciation and quartz veining all suggest a major hydrothermal event and InterMet will be drilling a deep diamond holes at Salt Creek and Lake Edge in February to test these untested significant gravity features.

Gold and Base Metal Exploration No work on gold and base metals was undertaken this quarter due to the drilling program described above. InterMet is planning further surface sampling within several areas of previously reported gold and base metal anomalism to define drill targets. Uranium Exploration Search Exploration for Hindmarsh Resources has completed 10 of the originally planned 16 IP traverses, for a total of 31.2 line kilometres of data (figure 1). The data were collected in two campaigns using a dipole-dipole configuration. The first campaign, undertaken in late August and early September 2006, used a 100m transmitter dipole with 100m receiver dipoles and two long traverses were collected to assess the viability of the technique. After a positive assessment of the data a further 8 traverses were collected in December of 2006 using a 200m transmitter dipole and a 100m receiver dipole configuration. The increased size of the transmitter dipole was undertaken to improve the quality of the signal strength for the deeper dipoles. Figure 2 shows the location of IP Traverses on EL 3467. Preliminary assessment suggests the presence of a number of significant conductors, the source of which could be graphite or sulphides. Further IP work, following up on these anomalies and extending the completed lines and completing the regional lines, is planned for the next quarter. These IP surveys will also provide valuable information in the search for base metals within the Triumph Prospect. Geochemical sampling within this area has reported anomalous gold, lead and copper values and represents a major exploration target.

Coulta Project (EL 3314, ELA 3671 & ELA 230/06 – 100%, WPC Uranium earning 80% in uranium on EL 3314 and ELA 230/06) The project area is prospective for Komatiite hosted nickel, Volcanic Hosted Massive Sulphide, Archaean orogenic gold and Palaeochannel Hosted Rollfront Uranium Nickel, Gold and Base Metal Exploration The first stage of the PACE drilling program on EL 3314 was completed on November 29 2006. 22 holes were completed for a total of 609 metres, intersecting basement rocks at shallow depths (Figure 3). However, due to drilling difficulties, the drilling failed to intersect any lithologies which would explain the aeromagnetic data due to difficult drilling conditions. Modeling of the magnetic data showed the magnetic features are between 50-90m deep and the drilling failed to penetrate to the required depth. InterMet is currently re-drilling up to 10 holes with the aim of intersecting prominent magnetic features outlined by the recent aeromagnetic survey. InterMet interprets these features to be part of the Archaean greenstone sequence intersected by Werrie Gold to the north of the tenement. InterMet’s drilling of similar magnetic features in the Mount Hope area intersected a sequence of mafic and felsic
- 6 - InterMet Resources Limited seafloor volcanics with interlayered magnetite rich pelitic sediments. These rocks are termed the Hall Bay Volcanics and are considered prospective for volcanic hosted massive sulphide and gold deposits. The second phase of drilling will be completed by mid-February with results expected by end of March. Results from the first drilling program include: Hole COU003 - 51 ppm Ag 38-41m Hole COU006 - 481 ppm Cu (5-6 m); 324 ppm Zn (5-6 m); 1076 ppm Co (6-10 m) Hole COU009 – 3.9 ppb Au (8-12 m) The second drilling program will include extending the depth of COU003 and COU006. COU003 bottomed in magnetite and pyrite-bearing granitic rock and hole COU006 was located in the closure of a prominent fold closure on the new aeromagnetic data. Figure 3 Location of holes from Coulta Drilling program Uranium Exploration Two holes (COU001 and COU002) intersected relatively thick sequences of oxidized and reduced sands with interlayered carbonaceous and pyritic sediments, indicating good potential for rollfront uranium. These two holes are located within the Cummins Palaeochannel and samples will be submitted for uranium analysis by InterMet’s joint venture partner, WCP Uranium Ltd.
- 7 - InterMet Resources Limited Cocata Project (EL 3462 and 3463 – InterMet 100%, Uranium Equities Ltd earning 80% in palaeochannel hosted and unconformity-related uranium; Silver Swan Group earning 80% in all minerals with the exception of palaeochannel hosted and unconformityrelated uranium; ELA 690/06 ) The project area is prospective for Rollfront Uranium, IOCG and Orogenic Lode Gold Uranium Exploration Uranium Equities Ltd (UEL) together with Silver Swan Group (SSG) are planning a 1 km x 1km grid gravity survey over most of the Cocata Project. The gravity survey is aimed at delineating the palaeochannels within the project area and to aid in determining drilling targets. Following a review of the gravity data, UEL plan to drill several traverses across the palaeochannels in April 2007. Exploration by Uranium Equities Ltd will also focus on assessing the unconformity-style uranium mineralization potential at the base of the Mesoproterozoic rocks (Blue Range Beds). With the addition of a new gravity dataset, modelling of the basement will be undertaken with a view to isolate areas where the target horizon is most shallow and accessible for drilling. No examples of unconformity-style uranium are yet known from the Gawler Craton, but, the prospectivity of this region for this style of mineralization has recently been recognized by PIRSA and others including Afmex and SXR Uranium One. Gold and IOCG Exploration The above mentioned gravity survey is also aimed at providing potential IOCG targets. The current regional gravity is poor with stations approximately 7 km apart. Regional aeromagnetic data show this area has multiphase Hiltaba Suite intrusives, an important associate for IOCG targets. ELA 690/06 InterMet has applied for a new tenement to add to its uranium properties. However, Iluka Resources have also applied for the same tenement. ELA 690/06 is approximately 700 km2 and is centred on Mount Wedge and is located adjacent to EL 3462 (Figure 4). Mount Wedge is a prominent topographic feature and is composed of Mesoproterozoic Blue Range Beds. The Blue Range Beds are a sequence of conglomeratic sandstones which unconformably overlies interpreted Archaean basement. The Blue Range Beds were deposited in the east-west trending Itildoo Basin during a major tectonic extensional event during the waning stages of the Hiltaba Suite/Gawler Range Volcanic tectonothermal event. This event is one of the major ore forming events on the Gawler Craton producing IOCG deposits at Olympic Dam and Prominent Hill, as well as gold-only deposits at Tunkillia, Earea Dam and Barns.
- 8 - InterMet Resources Limited Figure 4 Location of ELA 690/06 and InterMet’s Cocata Project InterMet believes that the environment is right for unconformity-related uranium mineralization. The Archaean basement rocks contain beds rich in carbonaceous material providing a suitable trap site while the Blue Range Beds contain clasts of Gawler Range Volcanics which are moderately enriched in uranium. The Itildoo Basin has undergone subsequent tectonic movement in the Permian Period (some several hundred million years ago) producing the Polda Basin, a deep sedimentary basin extending across central Eyre Peninsula. Significant elements important for the formation of unconformity-related uranium systems include: 1. a regional redox interface corresponding broadly to the unconformity separating an oxidised sedimentary pile from C and/or Fe2+ rich reductants in or near the basement; 2. sources of oxidised (high SO4 2-/H2S, evaporate interacted, moderate to high salinity) fluids in/above the sedimentary basin succession. Such fluids may transport numerous components and their progressive interaction with reductants may give rise to characteristic geochemical and mineralogical patterns at deposit and broader scales; 3. linked fault systems operative during sedimentary basin inversion or subsequent compression; 4. the mechanical contrasts of the basement with the sedimentary cover package; 5. uranium-enriched rocks in the basement and/or in cover sediments and volcanics ( see Figure 5) (From Unconformity-related uranium systems: Downunder and over the top by V J Wall – source http://www.earth2006.org.au/papers/extendedpdf/Wall%20Vic.pdf)
- 9 - InterMet Resources Limited Figure 5 Schematic cross section illustrating essential elements of unconformity-related uranium mineralization (Source http://www.earth2006.org.au/papers/extendedpdf/Wall%20Vic.pdf) The Itildoo Basin contains most if not all of the above criteria and has not been extensively tested for unconformity-related uranium mineralization. Tertiary sediments within the Polda Basin are considered prospective for sandstone hosted rollfront uranium mineralization. Previous company drilling for coal within the Polda basin has intersected a thick sequence of interbedded sands and lignites. These sediments have not been extensively tested for uranium mineralization. ELA 690/06 is also considered prospective for Archaean VHMS (lead-zinc-silver) and gold mineralisation. Previous groundwater sampling east of Mount Wedge produced significant zinc anomalies which have never been followed up. Recent drilling to the south by Lynch Mining has reported anomalous zinc associated with the Archaean Hall Bay volcanics. InterMet plans to undertake a program of regional surface sampling in the vicinity of these zinc anomalies followed by a program of aircore drilling aimed at testing the basement rocks.
- 10 - InterMet Resources Limited WATSON Project (EL 3313 and 3323, ELA 379/06 – InterMet 100%, Uranium Equities Ltd earning 80% in uranium; Silver Swan Group earning 80% in all minerals with the exception of uranium) Project area is prospective for Rollfront Uranium, Nickel and Gold Uranium Exploration Two recent groundwater drilling programs, supplemented by an airborne EM survey, have assisted in defining the palaeochannel and provided valuable geological information on the stratigraphy of the palaeochannel. There has been limited reconnaissance exploration for uranium in this region, but the fundamental geological attributes of uranium-rich source rocks, permeable sedimentary pathways such as buried palaeochannels and potential reducing sediments make this area an attractive target. Exploration by Uranium Equities will comprise palaeochannel mapping using remote sensing techniques mentioned above, a review of all geophysical and geological data followed by drilling. Southern Gawler Range Volcanic Project (EL 3461, 3598 and 3612) Project area is prospective Olympic Dam Cu-Au-U and Orogenic/Epithermal Gold Gold Exploration InterMet is currently assessing results from two previous calcrete sampling programs on EL 3461 with a view to further calcrete sampling to define drill targets. IOCG Exploration InterMet is planning a detailed gravity survey over all 3 areas. InterMet has requested Aboriginal heritage clearance for Lake Acraman to enable a detailed gravity survey.
- 11 - InterMet Resources Limited Garford Project (ELA 683/06) The project area has potential for Archaean Lode Gold (Challenger style) ELA 683/06 is located on the northern Gawler Craton and covers an area of approximately 351 sq km (Figure 6). The main mineral sought is gold hosted in the Archaean Christie Gneiss similar to Challenger gold deposit located approximately 40 km to the south. There has been a lack of exploration within the northern part of this prospective tenement which is located within the Tallacootra Conservation Park (Figure 7). Previous drilling by Goldstream/CRA intersected similar lithologies found in the vicinity of Challenger to the southwest of the tenement and these units on the aeromagnetic data appear to trend into the tenement. A prominent circular magnetic feature is located in the northern part of the tenement and potentially represents an IOCG target related to regional deformation on the Kararai Fault Zone. InterMet’s exploration program upon granting of the Licence includes: 1. Review previous company exploration including data compilation 2. Purchase aerial photography for area 3. Review existing calcrete data 4. Field visit to inspect access and reconnaissance mapping of regolith to test check effectiveness of calcrete sampling 5. Undertake calcrete sampling on a 800 m x 800m grid within areas not covered by existing calcrete sampling 6. Follow-up calcrete program if results warrant 7. Possibly a small gravity survey over prominent magnetic feature in the north of tenement – possible IOCG target Figure 6 Location of ELA 683/06
