Interview with Co-Founder and CEO Bradford Cooke. According to the CEO Endeavour Silver had a very good Q4 2020, though the official numbers are yet to be released. Both silver mines Guanacevi and Bolanitos are producing silver ounces on a high level. As the company moves forward, Terronera will be the next big step for Endeavour Silver. Terronera´s PFS shows excellent numbers with only 2.10$ all-in-sustaining-costs.
