Hinoba-an (Philippines) drilling update

For immediate release: 31st October 2005 DRILLING RESULTS FROM FIRST TWO HOLES OF HINOBA-AN (PHILIPPINES) INFILL DRILLING PROGRAMME COPPER RESOURCES CORPORATION ("CRC") Highlights Assay results from the first two holes of the infill drilling programme on the DJ Porphyry Copper Deposit show: * indications of mineralisation in the top 15 metres, a zone discounted in previous studies; * support for the conclusions of previous work below 15 metres; and * possible improvement in the previously interpreted grades in the vicinity of the new holes, based on preliminary analysis. Drilling Results Partial assay results have been received for holes CDD-001 and CDD-002, with the results as follows. These holes were collared near the centre of the DJ Porphyry Copper Deposit, and are part of a programme of 62 holes designed to infill the 59,000 metres of earlier drilling. Hole Interval Length (m) Copper % CDD-001(1)(2) 3m to 96m 93 0.50 Including(3) 24m to 39m 15 0.86 Including(3) 45m to 60m 15 0.65 CDD-002(2)(4) 6m to 141m 135 0.44 Including(3) 57m to 96m 39 0.71 (1) Results received to 96m (2) Calculated using a 0.20% Cu cutoff (3) Calculated using a 0.50% Cu cutoff (4) Results received to 195m Results for hole CDD-001 include the interval 0 to 96 metres out of a total length of 250.9 metres, and for hole CDD-002 the interval is 0 to 195 metres out of a total length of 217.9 metres. The balances of these holes are currently being assayed. The results from both holes support previous work, and a preliminary analysis indicates that calculated grades may be improved in the vicinity of the holes. Previous work on the deposit generally discounted the top 15 metres, as assaying generally was not carried out in this zone. One of the aims of the current work programme is to ascertain the potential of this zone; the latest results indicate that mineralisation is present in the top 15 metres in both holes. Future Programme The Bankable Feasibility Study ("BFS") sets out a programme of 62 holes to a maximum depth of 300m. The BFS is on schedule to be completed by December 2006.
