TORONTO, ONTARIO--(CCNMatthews - Feb. 23, 2007) - Silver Eagle Mines Inc. ("Silver Eagle") (TSX:SEG) is pleased to announce the official opening of its 100% owned Miguel Auza Mine located in the State of Zacatecas, Mexico, at which we were honoured to have in attendance the Governor of Zacatecas State, Senora Amalia Garcia, the Mayor of Miguel Auza, Senor Claudio Lopez, and a number of State and Federal officials involved in mining regulation.

Since start-up, the on-site mill has been processing a bulk sample, mainly comprised of low grade material, while testing the circuit and training new operators in the mill. The Company has now stockpiled in excess of 70 tonnes of poly-metallic silver, zinc, lead, and gold concentrate, which have been assayed by ERSA Global Laboratory and the Company's on-site laboratory, and are estimated to contain more than 7,000 ounces of silver. Negotiations are underway with a local smelter to process this concentrate, and shipments are expected to commence shortly. Test stoping commenced operation earlier this month and has provided additional material for processing. Silver Eagle has also commenced excavation for the foundation to install a second ball mill, which will allow the expansion of the processing capacity of the mill to 300 tonnes per day by September 2007. Approximately 6,000 tonnes of mineralized material remains stockpiled on surface, available for processing.

The ongoing exploration and resource definition program on the Miguel Auza Mine properties, which comprise an area of approximately 200 hectares within its 41,545 hectare San Pedro Resources property holdings (the "San Pedro Property"), is continuing, with four drills working. The objectives of this program are to increase the total resources and upgrade existing inferred resources to measured and indicated resources.

In addition to the ongoing work on the Miguel Auza Mine properties, Silver Eagle is pleased to announce a further US$550,000 exploration program in 2007, focused on properties outside of the Miguel Auza Mine property area. El Pantano (Pb, Zn, Ag skarn target), Loma Las Minas (gold prospect), Mesa El Cobre (copper prospect) and Cerro San Bartolo (tin prospect) are all located within the San Pedro property.

The continued development of our resources and mining assets and ongoing expansion of our mill will continue to bring substantial benefits to all our stakeholders, including those in the Miguel Auza area."
