Minefinders Corporation Ltd.: New High-Grade Gold at Dolores Adds to Underground Potential

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 23, 2006) - Minefinders Corporation Ltd. (the "Company") (TSX:MFL)(AMEX:MFN) reports that results from recent drilling on its Dolores gold/silver project in Chihuahua, Mexico have continued to expand its high-grade underground potential.

In particular, diamond drill hole D05-430 encountered several high-grade mineralized structures including a downhole interval averaging 33.46 grams per tonne ("gpt") gold and 17.4 gpt silver over 16 metres, approximately 60 meters beneath the planned, 72.5 million tonne, open-pit mine being developed at Dolores. This interval included six metres grading 84.25 gpt gold and 31.4 gpt silver.

These intercepts further confirm the presence of deep, high-grade gold mineralization at Dolores. They are believed to be contiguous with mineralization encountered in drill holes D05-421, D05-427 and D05-426, located 75, 425 and 450 metres, respectively, to the south. Of note, D05-426 intersected 38 metres grading 8.78 gpt gold, including one metre of 316.25 gpt gold, as reported December 13, 2005. None of this mineralization is included in previous resource estimates.

Company President, Mark Bailey, commented: "These results provide further confidence in the tenor of the high-grade mineralization at depth, beyond the present Dolores project reserves. As drilling progresses, the viability of mining these high-grade ores underground, in addition to the planned open-pit mine, becomes more apparent. We have now commenced a 20,000 meter drilling program to further expand and upgrade this mineralization."

The results from infill and step-out drilling in 2005 should increase the new Dolores resource estimates that are expected shortly. These results include the most recent holes from south of the open-pit deposit, those reported September 27, 2005 from the West Flank High-Grade Zone, and new shallow resources drilled in the area of the proposed leach pad.

Dolores Mine Development Update

The Company has four drill rigs working at Dolores. They include two diamond core rigs, a reverse circulation rig, and a water-well rig. The core rigs will be used for continued, deep and step-out exploration drilling, and for several engineering geotechnical tests that are required for mine development. The reverse-circulation rig will be used for shallower, near-surface exploration, and for continued condemnation drilling within the area of planned facility sites.

Detailed engineering for the Dolores mine is expected to be completed by the end of March; and the required mine environmental permits are expected in mid-March. Final construction and improvements on the Dolores main mine access road are on schedule for completion in April.

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).
