During the first week of April, the team of HECLA found itself in Lisbon to celebrate with happiness the thirteenth year of existence of the company there. As usual, technical presentations organized by some of us punctuated by fruitful exchanges accompanied these moments of collective work of the first day. Other moments of relaxation allowing the group to visit the Lusitanian capital and its magnificences without omitting to amuse in a cabaret of Fado punctuated the stay and all this in the beautiful state of mind which reigns within the company.
