Minefinders Provides Dolores Project Update-Mine on Schedule to Produce Gold this Year

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 16, 2007) - Minefinders Corporation Ltd. (the "Company") (TSX:MFL)(AMEX:MFN) reports on the progress of its Dolores 18,000 tonnes per day open-pit gold and silver mine in Chihuahua, Mexico. The Company and its contractors are progressing steadily towards the completion of construction and the transition to owner-operated production later this year.

Company President, Mark Bailey, commented: "The transition to production at Dolores is one of the most significant developments in our corporate history and we have been as careful and thorough in the construction phase as we were in the exploration phase. In building any new mine of size, it is not possible to predict what unexpected issues will arise, only that some will arise.

"I am pleased to report that we believe that we have successfully identified and addressed all such issues at Dolores and that we remain on track to commence mining in September and to achieve commercial production early in the second quarter of 2008. We are confident that the care that we have taken in all phases of this project to date will avoid unpleasant surprises in the subsequent financial performance of the Dolores mine."

- The power distribution facilities are under construction. The main generation equipment is on site and installed.

- The bulk of the outstanding work is in the leach pad and ponds construction, electrical installation, and pad solution delivery systems.

- Commissioning is targeted for late in the fourth quarter of 2007 with commercial production to be achieved in the second quarter of 2008.

- Completed independent audit and NI 43-101 report on updated Measured and Indicated resources with increases of 23.1% for gold and 21.3% for silver over the resources used in the Dolores feasibility study.

Detailed Update

Mining is scheduled to commence early September with initial production now targeted for late in the fourth quarter.

The biggest challenge in the critical path of the construction of the Dolores mine has been the timely completion of earthworks in the mountainous host terrain. Facilities site earthworks are now complete with the last major sites being the truck shop and office building. Earthworks for the phase-one leach pad have taken longer than expected, because of higher volumes of material than those estimated in the feasibility study, the requirement for additional blasting, and slow progress during an unusually wet monsoon season in July. However, a section of the phase-one pad will be available for lining in September and loading in late-October, in conjunction with the commissioning of the crushing plant.

The Company has commissioned much of the new mining equipment, including loaders, dozers, drills, graders, and five haul trucks. All of the remaining equipment has been received at site or at the Company's lay-down yards and is in assembly.

The Merrill Crowe plant is 83% complete and is expected to be operational in the fourth quarter. Foundation settlement issues that had been identified were evaluated by a team of geotechnical and structural engineers and permanent repairs are underway. The overall project schedule is not expected to be significantly affected by this issue.

The Power Plant is 21% complete with six 1.8-megawatt generators installed. Installation of fuel supply systems, switchgear, and wiring is ongoing with completion targeted for mid-October.

Hiring of mining and processing personnel is a priority now that equipment has been commissioned and is available for use in training. This is a priority and considered a critical path item to reaching full commercial production in the second quarter of 2008.

Of the $132 million in capital expenditures projected by the February 2006 Dolores feasibility study, approximately $111.6 million has been committed as of June 30, 2007. The additional unbudgeted work described above is expected to result in a total project cost in excess of the feasibility estimate; however these additional costs will be funded from existing cash.

Other Activity at Dolores

Exploration continues on the Dolores site with two drills following up on mineralization lying outside the current mine plan. Results from this drilling have been encouraging and will be released over the next several months as they are compiled.

Separately, the Company's Board of Directors has authorized management to proceed with the completion of a feasibility study for a flotation mill to be added to operations, in accordance with previously-announced down-stream mine development planning.
