Endeavour CEO Bradford Cooke commented: “2019 marked our 15^th year as a producing mining company. However, it was also a very challenging year for our mining operations, which impacted our sustainability performance. We made sweeping changes at each mine and initiated programs to improve our performance in all areas of the business.  As a result, we are already seeing improvements to benefit our sustainability.”

“In the first half of 2020, our safety performance has been much better as there is a higher level of safety awareness across all the mines. We received the “Empresa Socialmente Responsible” (Socially Responsible Company) distinction from the Mexican Centre of Philanthropy in Mexico for each of our operating mines at Guanacevi, Bolañitos and El Cubo.”

“Regarding the COVID-19 pandemic, we implemented our prevention and response plan and procedures to mitigate the virus risks in early March and were one of the first companies to be proactive as the health crisis progressed. On the community front, we have been distributing safety kits to high risk households in the areas of our operations and projects with various cleaning supplies and educational materials.”
