New Mineralized Zone At Dolores North Dome 

VANCOUVER - Minefinders Corporation President and CEO said, during the second quarter the Company continued to advance its 2010 exploration program. At Dolores, a drill program using one diamond core rig and one reverse-circulation rig identified a new mineralized zone, the North Dome. The presence of underground and extended mineralization to the south of the open pit was also confirmed. Drilling also commenced at the Company's grass-roots La Virginia property. The drilling is focused on testing the high-grade gold and silver mineralization identified within workings of the central La Virginia area. Initial results are encouraging and assay results are expected to be reported in the third quarter.

Minefinders reported the results of a pre-feasibility study for the La Bolsa property. The results of the study are positive and the Company is assessing a number of options to realize value from the La Bolsa project. Options under consideration include, but are not limited to, progressing to feasibility and a production decision or the sale or joint venture of the La Bolsa project.  National Instrument 43-101 compliant technical report will be filed with SEDAR. Gold and silver production in the second quarter reflects the lower grade ore stacked to the leach pad during the first quarter this year, said Bailey. However, production from phases 2 and 3 of the pit reached target levels during the second quarter, eliminating the need to supplement production by processing low-grade stockpile material. The average gold and silver grades stacked to the leach pad in June of 0.51 grams per tonne and 40.7 grams per tonne respectively reflect the higher grade ore that we are now starting to access. With grades increasing, tertiary screen repairs complete, optimization efforts well underway and the phase 2 leach pad ready for loading ore in August, production is expected to increase through the second half of this year.  The company's address is 2288-1177 W Hastings St., Vancouver, BC V6E 2K3, (604) 687-6263, fax: (604) 687-6267.
