Endeavour acquired its second and lowest cost mine, Bolanitos, in 2007, located in Guanajuato, the 2nd largest historic silver mining district in Mexico. Endeavour continued low level production until it discovered the first new orebody at Lucero in 2008. The mines were developed using mechanized, underground, ramp access and the plant was expanded over 300% to a 1600 tpd capacity. The Company subsequently discovered nine new orebodies, mined out seven orebodies, and is currently mining at LL Asuncion and Plateros.
