Ricus Grimbeek, President & CEO, noted, ” I am proud of the Caribou team for all the work they have put into restarting the mine. The team moved quickly to staff up the operation over the last couple months and get the mine, mill, and other systems and infrastructure into good working order. With this first truckload of concentrate leaving the site, we have achieved a major milestone safely and on schedule. I look forward to the continued safe ramp-up of operations. Thanks to everyone on the team and in the community for their efforts in making this a continuing success.”
