Minefinders Corporation Ltd.: Resource Expansion Drilling at Dolores Cuts 104 Metres Averaging 2.92 gpt Gold and 52.9 gpt Silver

Corporate news transmitted by DGAP – a company of EquityStory AG. The issuer is solely responsible for the content of this announcement. —————————————————————————— Minefinders Corporation Ltd.: Resource Expansion Drilling at Dolores Cuts 104 Metres Averaging 2.92 gpt Gold and 52.9 gpt Silver Vancouver, British Columbia, Canada. June 27, 2006. Minefinders Corporation Ltd. (the ‘Company’) (Frankfurt WKN: 859435; TSX: MFL; AMEX: MFN) reports that exploration drilling at its development-stage Dolores gold/silver project in Chihuahua, Mexico continues to encounter wide, bulk-minable intercepts surrounding narrower, high-grade feeder zones, beyond the limits of the current feasibility-designed open-pit. The drilling is part of an ongoing, comprehensive resource expansion program at Dolores. The latest results are from holes marginal to the planned Dolores open-pit mine, designed to test the potential expansion of the pit and future underground minable mineralization. Drill holes D06-436, D06-437, D06-443, and D06-449 are typical of mineralization encountered within the mineralized south breccia pipe with multiple intercepts occurring over a wide area. Significant intersections beyond the current mine plan, include: – D06-443 – 104 metres grading 2.92 grams per tonne (‘gpt’) gold and 52.9 gpt silver or 3.81 gpt gold equivalent(i) (‘Aueq’), including 25 metres grading 6.42 gpt gold and 117.5 gpt silver. This hole also cut 1 metre assaying 17.69 gpt gold and 2095.5 gpt silver. Intercepts occurring between 352 to 530 metres down hole in D06-443 are located 20 to 40 metres west of the currently designed pit wall with the deeper intercepts occurring from 34 metres to 110 metres below the planned pit bottom. – D06-449 – 81 metres grading 3.12 gpt gold and 39.6 gpt silver, with 6 metres assaying 19.62 gpt gold and 294.1 gpt silver extending high-grade mineralization from 50 to 120 metres below the planned pit bottom. In addition, drill hole D06-430, previously reported on January 23, 2006, extended high-grade south breccia pipe mineralization (16 metres averaging 29.8 g/t gold) 60 metres below, and 25 metres south, of the present pit design. Also included among the new results, drill holes D06-435, D06-437, D06-441 and D06-445 are north of the Central Dome and 500 to 1,000 metres north of the south breccia pipe. Drill holes D06-438, 439, and 440 were engineering holes for the reservoir site. Holes D06-446, 447 and 448 were condemnation holes in the leach pad area.

Drill intercepts are core intervals and true thickness has not been determined. Exploration drilling continues with three drill rigs currently on the property. Additional deep drilling is targeted to extend high-grade mineralization 100 to 150 meters beyond the deepest hole completed to date. Assay results are pending for holes D06-450 through D06-460. In total, 70 additional core and reverse-circulation drill holes have now been completed on the property over the past year, for condemnation, engineering, and water well test work. Dolores Resources and Reserves The Company is presently assessing the impact on the Dolores reserves of the increase in the resource base that was reported in its news release dated April 25, 2006. The impact on the Dolores reserve base of the results of the current drilling will be assessed as engineering studies progress. As shown in Table 2, at present, the total measured and indicated resources at Dolores (which include the proven and probable reserves currently being developed at the Dolores mine, shown in Table 3) are estimated at 3.06 million ounces of gold and 149 million ounces of silver, contained in 118.4 million tonnes (as reported on April 25, 2006).

Dolores Mine Development Update Development of the Dolores mine continues with construction started on the man camp and temporary office complex. Earth works are expected to start shortly in the leach pad and crusher areas with the finalization of construction contracts. Down payments have been made on all critical mine components, including crushers and mining equipment, to maintain delivery dates. Several pieces of ancillary equipment have been purchased and will be imported as soon as storage area is completed. Further updates on mine construction will be provided, as milestones are met. Quality Control and Assurance All analyses reported are fire assay analyses for gold and multi-acid digestion with AA analyses or fire assay analyses for silver, and completed by either Chemex Labs of Vancouver, Canada, or Inspectorate Labs of Sparks, Nevada. Samples from these intervals were comprised of HQ or NQ core all representatively split prior to analysis and transported by the labs to sample preparatory facilities in Hermosillo, Mexico (Chemex) or Durango, Mexico (Inspectorate).
