Bear Pass Project


SIZE:6,400 hectares
TARGET:District scale potential for multiple types of commodities & deposits
INFRASTRUCTURE:Electrical transmission line and paved Stewart Highway (37A)
  • Presence of (metalliferous) Early Jurassic (Texas Creek) intrusion in the Bear Pass area;
  • Large areas of intense pervasive alteration suggest an altered cap at the top of a large system;
  • Abundant evidence of large, continuous faults and shear zones that provided channels for mineralizing fluids;
  • Alteration and mineralization seen along these continuous channels over a large area of ground in the Bear Pass area


Compilation of historic exploration data and production results laid the foundation for a field program in 2018. That work identified a mineralized system which is inferred to be the same age as that at the producing Brucejack Mine, 48 km to the north, and geologically similar to that at the historic Silbak Premier Mine, 20 km to the southwest. The core of the system, known as the Bear Pass Pluton, was examined using isotopic age dating and other techniques and AUX determined that it is an Early Jurassic intrusion with strong potential to generate and host precious metal deposits.


The Bear Pass has a long history of mining and exploration, beginning in the early 1900s. Numerous gold-silver and base metal occurrences were explored, with several being developed into mines. In the early days, access was by packhorse or on foot, so that only exceptionally high-grade deposits were exploited. Exploration, until recently, was constrained by the fractured ownership, with titles to more than 100 parcels being locked up in the form of Crown Grants from the early 1900s until recently. Over a 12-year period AUX secured much of the ground that was previously covered by these Crown Grants, and recently augmented its holdings based on the emerging geological interpretation.
