Endeavour Silver Clarifies Technical Disclosure for the El Cubo Mine and Guadalupe y Calvo Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 5, 2012) - Endeavour Silver Corp. (TSX:EDR)(NYSE:EXK)(FRANKFURT:EJD) announced on April 15, 2012 that it had entered into an agreement to acquire the El Cubo mine in Guanajuato State, Mexico and the Guadalupe y Calvo ("GyC") property in Chihuahua State, Mexico from AuRico Gold Inc. Endeavour hereby wishes to clarify its technical disclosure for El Cubo and GyC.

In the April 15 news release, mineral reserves and resources were jointly disclosed by Endeavour and AuRico for the producing El Cubo mine and the GyC exploration project. The reserves and resources were provided in AuRico's annual information form dated March 29, 2012 for the year ended December 31, 2011. The information provided by AuRico included the following:

(a) Estimates of proven and probable reserves, measured and indicated resources and inferred resources at El Cubo; and

(b) Estimates of indicated and inferred resources at GyC.

For Endeavour's purposes, these estimates for El Cubo and GyC are considered to be historical estimates under National Instrument 43-101 ("NI 43-101") as they were prepared by AuRico before Endeavour entered into the agreement to acquire the projects from AuRico. No NI 43-101 technical reports have been filed in this connection by AuRico. The estimates were disclosed by Endeavour without providing the customary information and cautionary language pertaining to historical resource disclosure as required by NI 43-101.

An Endeavour qualified person has not done sufficient work to date to classify these historical estimates as current mineral reserves and resources. Endeavour is not treating these historical estimates as current and the historical estimates should not be relied upon.

Endeavour is currently conducting a detailed due diligence program designed to verify the historical estimates for the El Cubo mine and the GyC project with a view to compiling current mineral reserves and resources in accordance with NI 43-101.

In the April 15 news release, a preliminary economic assessment ("PEA") of GyC was jointly disclosed by Endeavour and AuRico. The PEA was prepared by AuRico as of March 5, 2012 but has not been filed by AuRico. As a result, for Endeavour's purposes, the disclosure of the PEA is not compliant with NI 43-101 and is therefore retracted by Endeavour and should not be relied upon. Endeavour intends to treat the GyC property as an exploration project and does not intend to use or update the economic assessment until further exploration has been completed.

Endeavour expects to close the El Cubo transaction upon receipt of approval by the Mexican competition anti-trust commission. Since the signing of the definitive agreement, Endeavour has been conducting additional detailed due diligence on El Cubo in order to develop its own updated reserves, resources, mine plans, production forecast, capital and exploration budgets, which it plans to release after the closing of the transaction.
