We work hard to ensure that our management and employees understand our approach to sustainability so that it is embedded in our decision-making processes. Doing so helps us gain local trust and confidence, leaves a positive legacy, and enhances our ability to grow.”

“During 2018, Endeavour Silver was recognized as one of the top companies in Canada for corporate citizenship by financial media company Corporate Knights and was named one of the 'Top 40 Responsible Corporate Leaders.' This award recognizes medium sized businesses who are stepping up to the sustainability challenges of today, which is driven by our employees who are committed to strengthening local communities while protecting the environment today and for future generations. In addition, we received the Empresa Socialmente Responsible (Socially Responsible Company) distinction from the Mexican Centre of Philanthropy in Mexico for our operating units in Guanacevi, Bolañitos and Cubo.”

“The theme of our 2018 report is 'Lasting Commitment,' reflecting our commitment to the communities in which we operate and affect and serving as a reminder that creating value is a continuous focus for us. Safeguarding worker safety, protecting the environment, supporting the well-being of local communities and constantly trying to improve and expand our business, these are some of our key commitments that lead to success.”

Updated Technical Report for the Terronera Project

Endeavour has filed an updated Technical Report on the Terronera Project with Mineral Resource and Reserve Estimates. The Mineral Resources for the two deposits (Terronera and La Luz) are presented in the first two tables and the Mineral Reserves are presented in the third table below.

1. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
2. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve.

4. The cut-off grade is 150 Ag Eq g/t
5. Historical mined areas were depleted from the Terronera Vein wireframe and Mineral Resource model.
