Re: Drilling Update

Ovoca Resources PLC 26 July 2005 Ovoca Resources plc ('OVX Dublin OVG London' ) Update on Olinenskoye and Leshaya South Drilling Highlights • Drill Hole BF-045 intersects 88.6 grammes per tonne gold (2.85 ounces per tonne) over 1.5 meters on Oleninskoye No 3 Deposit. • Follows recent results from the drilling programme on the Leshaya South Deposit from drill holes BF-041 with 1.5 metres at 12.3 grammes per tonne gold and 1.7 metres at 80.3 grammes per tonne and BF-044 with 2 metres at 211.0 grammes per tonne. • 17 diamond drill holes completed on Oleninskoye No 3 Deposit with assay results for 9 outstanding and a larger drill rig scheduled to start work on 2006 programme. • 4 diamond drill holes completed on Oleninskoye No 7 Deposit and 4 holes on South Leshaya Deposit with assay results for 3 holes outstanding. • A table of drilling results is included at end of this announcement. The Ovoca licence in the Former Soviet Union covers an area of 152 square kilometers along the Kolmozero-Vorony Greenstone Gold Belt in the Kola Peninsula in northwest Russia near the Finnish border. The licence measures some 27 kilometres along the trend and there are 8 known gold deposits. Ovoca is currently carrying out a diamond drilling and trenching programme on the Olennskoye (including the Leshaya South Deposit) and Nylam gold and platinum prospects. OLENINSKOYE Oleninskoye No 3 Deposit is sub parallel and approximately 250 metres to the north of the Oleninskoye No 7 Deposit. The vein systems are steeply dipping at an average of 70 degrees to the horizontal and the drill holes are inclined at 60 degrees to intersect the veins across the structure. To-date Ovoca has completed 17 diamond drill holes on Olinenskoye No 3 Deposit on a 150 metre by 150 metre grid. Assay results for 9 of these holes are awaited. The zone currently measures 900 metres along strike and 225 metres down dip and is open in all directions. A further 12 holes are planned in Q3 and Q4 2005 of which 5 holes of 150 metres depth will follow the vein along strike to the east and west at 150 metre intervals where the gold mineralisation is open. In Q1 2006 a further programme is scheduled for 500 to 700 metre deep holes on Oleninskoye No 3 when a larger drill rig is scheduled to start work. Gold grades appear to increase with depth. In addition to the diamond drill holes Ovoca has cut 15 surface trenches and channel sampled the bedrock across the veins. Assay results from 4 of these trenches have been received. Overburden thickness prevents trenching from following the strike to the east and west of the known mineralised 900 metre strike length. Assays are carried out for gold, platinum, palladium and silver. Currently Oleninskoye No 3 Deposit is the main drilling and trenching target having a Russian P1 + P2 category resource of 450,000 ounces of gold at 13.9 grammes per tonne prior to the commencement of drilling by Ovoca. To-date Ovoca has completed 4 holes on Olinenskoye No 7 Deposit and a further 3 are scheduled for this year. The assay results from 2 of these holes are awaited. A total of 5 surface trenches have been completed the best of which gave 50.2 grammes per tonne gold over a 1 metre thickness. LESHAYA Leshaya, a new vein structure discovered by the ongoing geochemical surveys, is approximately 4 kilometers to the northwest of Oleninskoye and sub parallel to it. At Leshaya, Ovoca has completed 4 drill holes as follow up to the 2004 geochemical survey results. Hole BF-041 intersected 12.3 grammes per tonne gold from a drill depth of 7.0 to 8.5 metres and 80.3 grammes per tonne over 1.7 metres at 86.8 and 88.5 metres depth. Hole BF-044 intersected 211 grammes per tonne over 2 metres near surface. Hole BF-043 reported 26.5 grammes per tonne over 1.6 metres from 55.1 to 56.7 metres depth. The geochemical survey is continuing around Leshaya to determine the possible extensions of the mineralised veins which will form the basis of the next drilling campaign on this deposit early next year. Oleninskoye No 7 and Leshaya South have, in the recent past, proved to warrant additional drilling. No resources have yet been calculated for Leshaya. NYALM Nyalm No 1 and Nyalm No 2 stockworks are some 16 kilometers to the south east of Oleninskoye. Nyalm No 1 zone measures 50 by 160 metres and tested to a depth of 100 metres in 15 Russian drill holes. Nyalm 2 measures 200 metres along strike and has been tested to a depth of 50 metres in 8 shallow Russian holes. These two stockworks are open along strike and down dip and contain an estimated 450,000 ounce of gold at 3.8 grammes per tonne in P1 and P2 resource category. A geochemical survey is being completed on these areas and new anomalies have been identified. Because of the thickness of the glacial till trenching is difficult in this area and a drilling programme is scheduled for next year. OTHER DEPOSITS Other known mineralisation occurs at Pellapahk (gold, copper, molybdenum porphyry), Verhkny Nyalm and Mudchechaive, areas have yet to be studied. Ovoca's primary task is to confirm and increase the Russian resources using JORC internationally acceptable standards of estimation. The true thicknesses of the intersections have not yet been determined and the assays are uncut. All assays in excess of 5 grammes per tonne gold are re-assayed and a programme of 1 in 10 samples to a second accredited laboratory has been initiated. To-date Ovoca has completed 25 drill holes in 3,434 metres of drilling Currently assays for 12 of these drill holes and 10 trenches are awaited, mostly from Oleninskoye No 3 deposit. The results will be published as they are received. Plans, cross sections and longitudinal sections are being updated and will be posted on www.ovoca.ie as soon as they are complete.
