OUR

HISTORY

Archer Cathro was incorporated in 1965 by founders Al Archer and Bob Cathro, former United Keno Hill Mines engineers who saw potential for a consulting company specializing in Yukon mineral exploration.   Since then, five generations of partners have successfully explored in Yukon, British Columbia and all over the world.  We proudly embrace our 60-year history, which includes a track record of significant discoveries, project advancements, important technological innovations and countless stories.  Today, our team shares the same passion for mineral exploration as its founding partners and is motivated to continue driving discovery for decades to come.
