Minefinders Provides Update on Status of Remediation Work on the Phase 1 Leach Pad at the Dolores Mine

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/28/10 -- Minefinders Corporation Ltd. (TSX: MFL)(NYSE Amex: MFN) reports that remediation work on the phase 1 leach pad at the Company's Dolores Mine continues.

As reported on August 4, 2010, a tear was identified in the phase 1 leach pad during June this year. Remediation work commenced immediately thereafter and, as a result, leaching of a significant portion of the phase 1 leach pad was suspended pending repair of the tear. Remediation work was initially expected to be completed by the end of August 2010, however, significant rainfall in the Dolores region during the third quarter exacerbated the damage and necessitated the intermittent suspension of remediation activities as working conditions with respect to repairs had become unsafe.

In mid-September, the Company implemented a revised remediation plan. The remediation work has negatively affected production of gold and silver in the third quarter and is also expected to result in lower than planned metal production in the fourth quarter. The decrease in production is expected to be temporary as stacking to the recently constructed phase 2 leach pad has been accelerated to full production levels and leaching of material on phase 2 began in mid-September. Non-leached crushed material from the phase 1 pad will be moved to the phase 2 leach pad in order to accelerate metal recovery.

The phase 2 leach pad provides capacity for over three years of planned production. As the volume and duration of ore stacked on the phase 2 leach pad increases, production of gold and silver will increase. Fiscal 2011 gold and silver production is not expected to be affected by the remediation work on the phase 1 leach pad.
