Guanaceví, our first and highest-grade silver mine
Acquired by Endeavour Silver in 2004, Guanacevi is our first and highest-grade silver mine. It is located in a historic silver mining district in Durango, situated in northern Mexico. Shortly after the acquisition closed, management discovered the first high-grade orebody and production commenced in 2005.
The mines were developed using mechanized underground ramp access and plant capacity was expanded by 100% to 1200 tpd. To date, the Company has discovered a total of eight new orebodies along the 5km length of the prolific Santa Cruz vein. Currently, Guanaceví provides steady employment to over 500 people and engages approximately 400 contractors.
In 2019, following the implementation of financial improvement measures, Guanaceví completed an operational turnaround that materially improved mine profitability. The development of two new orebodies – Milache and Santa Cruz Sur (SCS) – together with the acquisition of the Ocampo concession mining rights covering the El Curso property, have provided sufficient ore and flexibility to increase mine output and achieve plant capacity. The El Curso concessions are subject to a sliding scale royalty based on realized silver prices and are payable to a subsidiary of Groupo Frisco.
Currently, there are three orebodies being mined at Guanacevi: El Curso, Milache, and Santa Cruz Sur. Additionally, we allow for up to 20% of total ore milled to be purchased from local artisanal miners.
