======================================================================= News Release - April 8, 2010 Minefinders Receives Positive Assessment Of A Mill Addition At The Dolores Mine ======================================================================= (All figures are in United States dollars unless otherwise stated) Vancouver, British Columbia � April 8, 2010 � Minefinders Corporation Ltd.

is pleased to report that it has received the results of an independently prepared draft pre-feasibility study (the �study�) assessing the addition of a mill at its Dolores Mine in Mexico. The mill addition scenario contemplated in the study represents one of a number of mill options under consideration by Minefinders.

The results of the study support, and the Board of Directors has approved, progression to a detailed feasibility study on a mill addition at Dolores.

In advancing the feasibility study, additional mill options will be reviewed and evaluated in the context of the economic considerations pertinent to Minefinders prior to a construction decision.

Once Minefinders has reached a decision with respect to a mill addition, a technical report supporting the decision will be filed. �We are very satisfied with the results of the study which has confirmed our expectation that the addition of a mill would be of benefit to the operation�, said Mark Bailey, President and CEO.

�We are committed to responsible growth at Dolores and are progressing on that basis.

Minefinders is in the enviable position of having a profitable heap leach operation at Dolores which allows us to be thorough in investigating and considering a number of mill options.

These include scenarios with lower initial capital costs that both capture the high grade ore in the open pit and provide the infrastructure necessary to develop a new underground mine at Dolores in the future if it is prudent to do so.� To read the complete news release, please see our web site at http://minefinders.com/_resources/nr/MFL-NR-4-8-10-FINAL.pdf ======================================================================= Click or copy and paste the link below to unsubscribe from this list http://dissemination.blendermedia.com:81/u?id=1371438U&u=http://minefinders.com/unsubscribe/index.php?status%3Dunsubscribe&w=F&c=F&l=minefinders_com =======================================================================
