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 suggesting an altered cap at the top of a very large system;
  • Abundant evidence of large, continuous faults and shear zones, channels for mineralizing fluids and:
  • Alteration and mineralization seen along these continuous channels over a large area of ground in the Bear Pass area therefore:
  • A large land package prospective for intrusion related gold deposits has been assembled and:
  • Co-operation of AUX and Mountain Boy Minerals in exploration of their mutually held large, prospective area of the Golden Triangle.

Drill permitting is underway and planning for drilling is a follow-on to a year’s work by the AUX geological team. Compilation of 100 years of historic exploration and production results laid the foundation for last year’s field program, which was conducted by a five-person geological team. That work identified a mineralizing 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 measurement and other techniques and AUX determined that it is one of the Early Jurassic intrusions, with exceptional potential to generate and host precious metal deposits and which are associated with the majority of gold-silver mineralization in the Golden Triangle.

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. AUX, over a 12-year period, secured much of the ground that was previously covered by these Crown Grants, and recently augmented its holdings based on the emerging geological interpretation.

The significance of the Bear Pass Pluton was not previously recognized because of this diverse, small-scale mineral tenure ownership; coordinated exploration was not possible between the numerous small parcels. Last year, the AUX geological team, working under a cooperative exploration agreement with Mountain Boy Minerals, carried out the first-ever comprehensive exploration program in the Bear Pass region. The recognition of a Texas Creek intrusive unit is but one of the geological insights gained from that program.
