• On Thursday May 21, 2009, 8:00 am EDT

TORONTO, ONTARIO--(Marketwire - May 21, 2009) - ECU Silver Mining Inc. (TSX:ECU - News) is pleased to report that it has poured a total of 78 silver/gold dore bars in the past month.

The silver/gold dore bars have a total weight of 1,575 kilograms (kg). Assays indicate that these dore bars contain a total of 626 ounces of gold and 30,544 ounces of silver.

We have also poured an additional 13 bars this week, assays will be known later, and expect to pour 300 to 450 kg of dore per week, depending on silver assays of the feed.

We have sent samples of our dore to different interested buyers and are in the process of reviewing several term sheets from these potential buyers of our dore bars. The interest in our dore product has been very strong and we have so far received offers from seven different buyers. We have sold 730 kg of dore bars to date and have a planned shipment of another 1,100 kg for later this week to two separate buyers.

The oxide mill continues to operate very well. Over the next few weeks, we plan on increasing the throughput of our gold and silver recovery oxide plant to a rate of 500 tonnes per day.
