core to the way we do business, and that is what makes us different. 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.”

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. It is reasonably expected that the majority of the Inferred Mineral

Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

3.   The Mineral Resources in this Updated Technical Report were estimated using the CIM Definition Standards for Mineral

Resources and Mineral Reserves.

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.

6.  Mineral Resources are inclusive of Mineral Reserves.
