The Buchans deposits rank as the world's highest grade polymetallic (Zn-Pb-Cu-Au-Ag) VMS deposits with a Zn equivalent grade of 48%* (produced 16.2 Mt @ 14.51% Zn, 7.56% Pb, 1.33% Cu, 126 g/t Ag and 1.37 g/t Au). Compared to other major VMS camps worldwide it has seen only modest exploration and research, especially in the past 25 years, and most of the work preceded a new recognition of the geological model.
In 2014, Altius was able to consolidate a 22,000 Ha land package in the camp, began compiling and assessing historic data, and has initiated a modern multidisciplinary exploration campaign.
An EM survey was completed in 2017, developing 35 drill-ready targets.
