Resource Expansion Drilling Programme and Results Figure 1 (please see the link at the end of this announcement) shows the location of the Co-O Mine and Figure 3 shows all the diamond drill holes drilled and in progress around the Co-O Mine since December 2006 up to 21 January 2008. Figure 4 (please see the link at the end of this announcement) shows the current three dimensional model of the vein system which will be updated in April 2008. All drill holes completed by the end of February 2008 will be included in a new interim resource estimate that is expected to be completed in April 2008. However, drilling will continue after the resource estimate is completed. Since August 2007, a total of 13 new surface holes have been completed with assays awaited for hole MD 55. Hole MD 50 was abandoned due to bad ground conditions in a fault zone.Table V lists the diamond drilling results from the Co-O Mine for drill holes MD 46 to MD 58 (excluding MD 50 and 55) and for underground drill hole DBH 03. Previous announcements on the Co-O drilling on 9 July, 15 May and 28 February 2007 contain information regarding drilling and surveying techniques, comments on vein interpretation and methodologies and assaying protocols.

(v)MD 55 not yet assayed and MD 50 abandoned. West of the Oriental Fault The drilling since August 2007 has now successfully demonstrated that the three New Catto Veins continue to the west of the Oriental Fault for approximately 200 metres and may extend through to surface similar to the Central Vein. Consequently, development is underway to intersect them on the 3150 metre or adit level, on the 3100 metre level, and on the 3050 metre level as intersected in underground drill hole DBH 3. It is anticipated that stoping should commence from the west New Catto Veins on these three levels in the third quarter of this year. These veins are still open along strike to the west and at depth. East of the Oriental Fault Since August 2007, hole MD 48 (Agsao Shaft pilot hole) intersected one of the east New Catto Veins and returned confirmatory high grades. Hole MD 46 intersected 1.40 metres at 20.62 g/t gold at approximately 400 metres below surface which is one of the deepest intersections achieved to date. Mine Expansion Expansion works commenced during September 2007 and have proceeded well with approximately 70% of the activities focussed on the expansion. A total of 821 metres of development was completed in the last quarter to 31 December 2007. In the third quarter of 2008 it is anticipated that stope production should be underway from five levels in the mine, being the 3150, 3100, 3050, 3000 and 2950 metre levels. (a) Development of the New Catto Veins A new drive following underground drill hole DBH 3 on the 3050 metre level is underway to initially intersect the New Catto Veins to the west of the Oriental Fault before driving to locate the Catto Veins on the east side of the Oriental Fault. It is anticipated that this drive will intersect the veins on the west side in February and that stopes should be set up for production in the third quarter of 2008. (b) Beta Shaft The set-up for the new internal inclined Beta Shaft (footings, headframe and winder), to an inclined depth of 120 metres (100 metres vertical) is in progress following the drilling of the large diameter siter hole. Provided ground conditions are reasonable, ore production through the Beta Shaft should commence in the last quarter of 2008. (c) Agsao Shaft The new external Agsao Shaft, to an inclined depth of 240 metres (200 metres vertical) has commenced sinking following setting up of the head frame and associated infrastructure. The bottom of this shaft will be at the 2950 metre level and will be connected to the Beta internal inclined shaft at the same 2950 metre level. Plate 1 shows the Agsao Shaft headframe. Provided ground conditions are reasonable, ore production through the Agsao Shaft should commence early in 2009. (d) 3150 metre level Following the on-going success of the drilling for the Catto Veins to the west of the Oriental Fault, development is now underway to intersect these veins in March to the south of the Central Vein and to set up stopes. Stope production should commence in the third quarter of 2008. Co-O Mine Grid Power The Company has commenced installation of a new power line along the ore haul road to carry grid power from the Co-O millsite to the Co-O Mine. The current estimated cost of the power line is approximately A$1million which will reduce the cost of power by approximately 75%. At current diesel powered electricity generation costs, the line is anticipated to have a pay back period of less then one year. The timing of the completion of the power line will depend on the arrival of the long lead time items which are expected before mid-year and will follow the completion of a new sub-station in the town of San Francisco located approximately 25 kilometres to the north of the Co-O Plant. This will result in increased reliability of the power supply and upgrading of the line capacity to the project TAMBIS-BAROBO AREA Background At the Bananghilig Mine the Company undertook underground exploration and trial mining of several "high grade" veins based on the previous explorers' drill hole data bases consisting of a total of 29,477 metres of RC and diamond drilling in 344 holes The underground exploration and follow-up underground drilling has shown that interpreted high grade vein widths from RC holes have generally been exaggerated by the RC drilling by several orders of magnitude through down hole smearing of narrow high grade veinlets and are too narrow and too discontinuous to mine economically. Subsequently a programme of underground drilling has been completed, and geological mapping and assessment is in progress in combination with surface drilling which is continuing. Geology The Bananghilig Mine area is located on the northern edge of a large aero-magnetically defined alteration zone measuring approximately 9.5 by 7.3 kilometres as shown on Figures 5 and 6 (please see the link at the end of this announcement). The Tambis District is generally underlain by fine to coarse-grained andesitic and dacitic flows of probable pre-Tertiary age that constitute the basement rocks. Locally, the basement rocks show agglomeratic features and in places are cut by andesite to dacite porphyry dykes and bodies of hydrothermal breccias of various shapes and sizes. The southeastern part of the Tambis District is covered by a younger bedded sedimentary formation comprising basal mudstone, sandy clastics and agglomerates with massive white limestone as the uppermost member. The Tambis Caldera and Diatreme The Tambis caldera is manifested by geomorphologic signatures as deduced from subtle concentric drainage patterns and complemented by landsat imagery. These signatures suggest a northeast trending, truncated caldera system measuring approximately 10 kilometres along the northeast to southwest axis and 6 kilometres along the northwest to southeast axis. The caldera and diatreme breccia are located around the intersection of the regionally significant Barobo Fault (parallel to the Philippine Rift Fault) and the Lianga Bay Fault system, as shown on Figure 5. Figure 6 (please see the link at the end of this announcement), shows the detailed geology and drill hole locations. A sizeable elliptical-shaped diatreme breccia body, measuring approximately 1,000 metres along the northeast axis and about 750 metres wide, has been outlined based on diamond drilling and mapping in the Bananghilig area. The geological features, various breccia materials and associated overprinted hydrothermal alteration and mineral assemblages, suggest that the diatreme developed and evolved in the roof portion of a still buried stock or a similar intrusive body or bodies. The gold mineralisation styles correlated to the diatreme are in fractures and/or breccia in-fill in milled/ fluidised muddy matrix breccia bodies and coarsely brecciated/fractured andesitic-dacitic wallrock, and intra and post diatreme veins probably propagated from older fault systems and/or generated within and around the pipe-like breccia column during the diatreme's evolution. Alteration In the Bananghilig area, widespread silica-clay-sericite-pyrite hydrothermal alteration affects the volcanic wallrocks, the various breccia bodies and the hypabyssal intrusives associated with them. The alteration assemblage typifies that found in advanced argillic alteration zones. The outcropping alteration exhibits a strong potassium airborne radiometric anomaly. Mineralisation and Drill Results A programme of underground drilling has been completed from the underground development 50 metres below the collar of the L-170 shaft to confirm and explore the veins interpreted by previous explorers. A number of surface diamond drill holes were also completed at the time of the shaft sinking as well as recent additional drill holes. The early drilling concentrated on identifying high grade veins, but recent re-logging and re-assaying has demonstrated large zones of disseminated mineralisation associated with various diatreme and fault breccias and some of the subsequent intrusive rocks. Table VI summarises the drill results to date from surface drill holes (TDH holes) and underground drilling (TUG holes) as shown on Figure 8 (please see the link at the end of this announcement). A large number of wide intersections of 0.5 to 1.0 g/t gold and some highlighted copper values are not included in this table but are listed in the announcement in September 2007. Table VI.

TUG 002 (52.4 metres at 0.9 g/t gold horizontal) is also interpreted to have intersected mineralisation immediately under the limestone. In addition sporadic mineralisation in a similar position in TUG 003 to 1.8 g/t gold also suggests that the mineralisation continues along strike. TDH 008 intersected 21 metres of anomalous gold from 0.13 to 0.70 g/t gold also supporting the presence of gold immediately underlying the limestone sequence. If further drilling confirms this concept, then there is the potential to develop considerable tonnages of moderate grade mineralisation in this position. Drilling is continuing in the Bananghilig area targeting the vein systems specifically where they are hosted by intrusive, coarse-grained andesitic rocks. It has now been demonstrated that these competent rocks are superior host rocks for the formation of constrained high grade veins compared to the more permeable diatreme breccias where mineralisation is generally more diffused or disseminated. The Company has recently completed a comprehensive ridge and spur soil sampling programme along the Barobo Corridor and around the Sopon area totalling approximately 4,500 samples from several soil horizons. These samples are currently being selectively processed with results anticipated in the second quarter of the year. KAMARANGAN IRON ORE TARGET (TAMBIS AREA) During the recent ridge and spur soil sampling programme described above, an extensive area of weathered magnetite with secondary hematite skarn mineralisation was located (Figs 2 and 5 - please see the link at the end of this announcement). The magnetite skarn area is also marked by extensive alluvial gold workings from previous local sluicing operations. Magnetite is a magnetic iron oxide mineral that contains 72.36% iron. Its magnetic property permits recovery of a magnetite concentrate by relatively simple magnetic separation techniques. Skarn rocks are formed when hot fluids containing silica, iron and other metals emanate from intrusive rocks (such as granites or porphyry copper bodies) and come into contact with and react with limestones and other calcareous rocks. At Kamarangan the skarns are hosted by a banded limestone sequence which is older than the "younger" massive white limestone which outcrops prominently to east.

Work in Progress Underground exploration will continue to verify the drill results achieved to date and to assess mining conditions. Positive results from this work may justify production from these veins in the third quarter of 2008. Drilling will continue along strike to outline additional zones of mineralisation that could justify underground exploration and assessment. OTHER PROJECTS * Lingig (Das-Agan) Project The MOA covering MPSA application number APSA 024-XIII comprises two parcels situated to the north and to the east (the Lingig porphyry copper prospect) of the Co-O Mine and millsite as shown on Figure 2 (please see the link at the end of this announcement). As previously advised, drilling will commence as soon as possible, upon finalisation of permits. Road and bridge repairs for access are in progress. A detailed compilation of previous work was recently completed and is summarised below: The Lingig area was located as a result of an aid programme between Filipino and Japanese geologists and technicians in 1972 to 1974 over eastern Mindanao (Dept of Natural Resources, 1974). An initial 3,000 km² prospective area was located by geological and geochemical surveys and was subjected to additional geological mapping and geochemistry. A smaller 170 km² area was selected and subjected to detailed geological mapping and geochemistry followed by Induced Polarisation ("IP") geophysical surveys. A programme of five holes with pre-set depths of 250 metres was completed on five different targets. Geology and drilling results Figure 11 (please see the link at the end of this announcement) shows the current geology of the area as well as copper soil geochemistry and contoured resisitivity and frequency effect results of the Induced Polarisation survey. The surface mapping and drilling suggests that this is an intrusive complex with dacite, dolerite, diorite and quartz diorite rocks intruding a basaltic sequence. Epithermal veins up to 1 metre wide are generally gold poor and relatively base metal enriched. They have been worked sporadically by local prospectors. In 1997 Barrick Gold Philippines assessed the project for its gold potential through mapping and the collection of 110 rock samples. This work identified a circular feature (Fig. 2 - please see the link at the end of this announcement) that contains most of the mapped argillic alteration and a large elongate quartz veined breccia measuring 750 metres x 1,200 metres and located approximately 1,500 metres south of drill hole DDH1. Sampling returned gold values between 0.1 and 1.3 g/t gold. Fresh rocks with disseminated grains of sphalerite (zinc) and galena (lead) were found to have higher gold values ranging from 0.3 to 1.3 g/t gold than intensely weathered rocks. The lead-zinc association is consistent with generally accepted metal zoning that occurs around the periphery of porphyry copper deposits. In addition, within the circular feature, a second zone of silicified rocks with quartz stockworking was identified over an area of approximately 500 metres x 600 metres which assayed from 0.03 to 1.5 g/t gold. Recent reconnaissance has located bleached and silica-clay altered rocks with quartz veinlets approximately 300 metres to the north of DDH1. Drill hole DDH1 After passing through 100 metres of propylitically and argillically altered doleritic and basaltic rocks with erratic copper mineralisation, drill hole DDH1 intersected disseminated and stringer style pyrite and chalcopyrite mineralisation for 98 metres in increasingly argillically altered basaltic and doleritic rocks before entering higher grade mineralisation in phylitically altered quartz diorite porphyry. The graphic log of the drill hole is shown in Figure 12 (please see the link at the end of this announcement). Table IX. Summary of intersections in drill hole DDH 1 Depth (metres) Intersection Host rocks, alteration & mineralisation 0 to 100 Erratic values to Propylitically (chlorite and 0.89% Cu epidote) and argillically altered dolerite and basalt with disseminated and stringer pyrite, rare chalcopyrite. 100 to 198 98 metres @ 0.27% Propylitically and argillically Cu (clay) altered dolerite and basalt with a moderate increase of disseminated and stringer pyrite and chalcopyrite. 198 to 250 52 metres @ 0.65% Phylitically altered Cu (silica-sericite) quartz diorite porphyry with disseminated and stringer pyrite and chalcopyrite increasing with depth. Incl. 248 to 2 metres @ 4.93% 250 Cu, [End of Hole] 0.4g/t Au,10g/t Ag TOTAL: 100 to 150 metres @ 0.40% 250 Cu The DDH1 drill hole results bode well for a fully preserved porphyry copper deposit which is exhibiting increasing grades with depth, and suggests that DDH1's pre-set depth stopped short of the high grade core that is commonly present in these styles of deposit. Further drilling at this site was recommended but not carried out. The other four holes to the south intersected minor copper mineralisation. Drill holes DDH2 to DDH5 DDH2 intersected quartz diorite intruded by diorite dykes from 11 metres to the bottom of the hole at 250 metres. Both rock types exhibit weak propyllitic alteration. Minor copper mineralisation of 0.16% was encountered from 16 to 20 metres and 0.24% from 48 to 50 metres. DDH3 intersected basaltic rocks from nine metres to the end of the hole at 250 metres and which have been intruded by doleritic and quartz diorite dykes. The rocks have been affected by weak chloritisation and rare epidotisation. Minor pyrite occurs along fractures and pyrite-chalcopyrite stringers are rare with the highest copper value of 0.99% at 12 to 14 metres and all other values are less than 0.1% copper. DDH4 intersected basaltic and doleritic rocks from 7.5 metres to 96 metres and quartz diorite to the bottom of the hole at 250 metres. The quartz diorite exhibits an upper chilled margin and is cut by quartz diorite dykes at 138 and 216 metres. Except for one assay of 0.69% copper at 128 metres, all other copper values are less than 0.1% copper. DDH5 intersected dolerite from 15.20 metres to 69 metres, quartz diorite to 210 metres and dolerite to the end of the hole at 250 metres. The dolerite's alteration is propylitic and of a similar intensity as in holes DDH3 and DDH4. Hydrothermal alteration of the quartz diorite is weak. Copper mineralisation was encountered from 15.20 metres to 34 metres with 18.80 metres at 0.34%, from 52 to 54 metres with 2 metres at 0.69%, 68 to 70 metres with two metres at 0.69% and four metres from 230 to 234 metres with 0.34%. All other intervals were less than 0.1% copper. Discussion Drill hole DDH1 has intersected the top of a mineralised copper-gold-silver quartz diorite porphyry. The other drill holes indicate varying degrees of low intensity alteration and minor copper mineralisation probably associated with lithothogy boundaries and faults. Of particular note is the 98 metre disseminated copper halo above the quartz diorite, suggestive of an intense mineralising system, as well as the erratic copper values in the propylitic alteration envelope above this disseminated zone. This has similarities to the Lutopan orebody of the Atlas Toledo Mine where ore grade replacement mineralisation is hosted in volcanics for a width of 120 metres along a strike length of 900 metres (Mines & Geosciences Bureau, 1986). The Atlas Toledo orebodies are also similarly bounded by two parallel northeast-trending faults as seen at Lingig. Diorite and quartz diorite intrusive rocks are commonly closely associated with many porphyry copper deposits in the Philippines. Some examples are the Tampakan Deposit (resources of 2 billion tonnes at 0.59% copper and 0.23 g/t gold, www.indophil.com and Middleton et al., 2004), the Boyongan Deposit (resources of 300 million tonnes at 0.6% copper and 1.0 g/t gold, www.mgb.gov.ph, www.philexmining.com.ph), the Atlas Toledo deposits (resources of 1.53 billion tonnes at 0.41% copper and 0.24 g/t gold, www.atlasphilippines.com), the Hinoba-an Deposit (resources of 293 million tonnes at 0.36% copper, www.copperresources.com), and others. It is also noteworthy that copper mineralisation is more common in DDH5 than DDH2 to DDH4 and that DDH5 is located on the edge of the circular feature and its contained extensive argillic alteration zone and large breccia and stockwork bodies. * Abacus Project The Mines Operating Agreement ("MOA") with Abacus Consolidated Resources and Holdings Inc. covers Exploration Permit ("EP") application number 000028-XIII situated to the north of the Co-O mine and millsite as shown on Figure 2 (please see the link at the end of this announcement). The granting process for the Abacus EP is now being pursued. The ridge and spur soil sampling described in the Tambis-Barobo section above has covered the eastern parts of the tenement. * Saugon Project The Saugon Exploration Permit has been renewed and a regional soil sampling programme is planned. * Philsaga-Magnum Project (Magnum Gold NL earning 50%) No field work was conducted during the quarter. * Bunawan Mining Corporation JV (Medusa earning 50%) The Company has signed a joint venture agreement ("JVA") with Bunawan Mining Corporation ("Bunawan"), the Philippine operating company of ASX listed Sierra Mining Limited ("Sierra"), whereby Medusa, after completing satisfactory due diligence, will earn a 70% joint venture interest in Exploration Permit application ("EPA") 000037-XIII and Mineral Production Sharing Agreement application ("APSA") 000003-XIII (together the "Bunawan JV"). Medusa has completed tenement due diligence and upon satisfactory access being gained to the area, which is expected in the near future, Medusa has agreed to take a 9.9% placement in Sierra of 4.85 million shares (at an issue price of A$0.25, totalling A$1.21 million) with 2.425 million unlisted attaching options exercisable at A$0.30 each with an expiry date of 4 years from the date of issue. SAMPLING AND ASSAYING PROTOCOLS Samples are taken from mainly HQ sized and some NQ sized drill core. The selected sample intervals are halved by diamond saw and half the core is bagged, numbered and sent to the Company laboratory. In a small number of cases to confirm the geological logging, the selected interval is re-split and ¼ core re-submitted for assay. Initial sample preparation and assaying is undertaken at the Company's on-site laboratory. Samples are dried at 105ºC for 6 to 8 hours, crushed to less than 1.25 cm by jaw crusher, re-crushed to less than 3 mm using a secondary crusher followed by ring grinding of 700 to 800 grams of sample to nominal particle size of less than 200 mesh. Barren rock wash is used between samples in the preparation equipment. The samples are assayed by fire assay with Atomic Absorption Spectrometer (AAS) finish on a 30 gram sample. All assays over 5 g/t gold are re-assayed using gravimetric fire assay techniques on a 30 gram sample. The majority of samples which contain more than 0.5 metres at more than 2 g/t gold are re-assayed by McPhar Geoservices Phils Inc ("McPhar"), a NATA and ISO 9001/2000 accredited laboratory in Manila. The pulps are airfreighted to McPhar who fire assay 30 grams of sample using AAS finish and a selected number of samples are checked using gravimetric fire assay techniques. Duplicate samples and standards are included in each batch of check samples. When reporting results, where available, as McPhar is an independent laboratory, McPhar assays are given priority over the Company laboratory's results.
