Minefinders Provides Dolores Construction Update and Reports Third Quarter Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 15, 2007) - Minefinders Corporation Ltd. (the "Company") (TSX:MFL)(AMEX:MFN) today provided an update on construction and plans for its Dolores Mine in Mexico and reported financial results for the third quarter ending September 30, 2007.

Minefinders' President and CEO, Mark Bailey, said: "We made significant progress during the third quarter toward reaching our goal of achieving commercial production at Dolores in the second quarter of 2008. One of those milestones was reached in October with the start of pre-commercial mining at Dolores.

"Before year end, we expect to have an updated study on mine economics, incorporating new reserves and mine schedule with current operating cost and more relevant gold and silver prices, providing a clearer understanding of additional upside at Dolores and further positioning Minefinders to create value for shareholders in the near and long-term."

Dolores Progress Highlights:

- Mining activities in the pit commenced in October and the Company expects the first ore to be stacked on the leach pads in January 2008 as part of the commissioning process;

- Sufficient leach pad lining has been completed for initial loading of ore by the end of the year;

- All of the mining equipment and drills have been delivered to the mine or Company lay-down yards and equipment assembly is progressing. Loaders, dozers, graders, and 9 of the 15 Komatsu 100 tonne haul trucks are assembled and operating at the Dolores mine site;

- Generators, crushers, conveyors and processing equipment are substantially complete and the commissioning of various components will take place through the fourth quarter of 2007;

- Most of the key management team has been hired and recruiting and training of equipment operators is ongoing as mining activity escalates and the commissioning progresses;

- The on-site employee camp and facilities are finished and in full use;

- Houses for the new Dolores village are completed and the school, church, medical clinic and administrative centre are expected to be completed in November; and

- Issues with settlement of the foundation platforms for the screening plant and the Merrill Crowe facility were evaluated by independent geotechnical engineers and repairs are now complete for the screening plant foundation and will be complete for the Merrill Crowe platform in December.

The Company's Mexico subsidiary has increased its mine operations team to 131 employees, with an additional 400 contractors still working on completing construction and commissioning, leading to production.

The Company has engaged an independent engineering firm to incorporate the increase in resources, reported in July 2007, into new mine reserves and create a production schedule for use in updating the mine economics. The Company expects the updated mine economics and reserves to be completed by the end of the year.

In 2008, the Company will also undertake a feasibility study to examine the enhanced project economics that can be achieved with the addition of a flotation mill to process high-grade ore in the open pit and additional underground ore not contemplated in the previous feasibility study.

Third Quarter Financial Results:

The Company expects to have no revenue except interest income until Dolores commences commercial production in the second quarter of 2008. As a result, the Company expects to meet its cash requirements from funds in place or available through traditional revolving non-equity sources. As at September 30, 2007, The Company had US$44.4 million in cash and cash equivalents and net working capital of US$44.8 million.

The Company reported a net loss for the third quarter of 2007 of US$12.97 million (US$0.27 per share) compared with a net loss of US$0.9 million (US$0.02 per share) for the same period in 2006. Net losses for the first nine months of 2007 totaled US$13.85 million (US$0.29 per share) compared with US$5.4 million (US$0.12 per share) in the first nine months of 2006. A significant portion of the third quarter and nine month loss is the result of a $7.70 million non-cash provision for future income taxes recorded by the Company to reflect the recent changes in the Mexico tax legislation.
