Terry Harbort, President and CEO, Talisker Resources Ltd.
Terry is a specialist in the mapping and interpretation of ore geometries and controls covering various types of geological environments with direct applications to mineral economics. Currently CEO of Talisker Resources, Terry has spent his 27-year career dedicated to gold exploration in cordilleran and Archean environments working extensively for AngloGold Ashanti and the Osisko Group, including five years as Chief Geologist of Barkerville Gold Mines (now Osisko Development Corp.). Terry holds a PhD in Structural Geology and Tectonics from the University of Queensland, loves cooking and wine, competing in endurance events and ice climbing.
The Bralorne Gold complex is British Columbia’s only world-class orogenic gold deposit and is one of the largest vein systems in the North American Cordillera, surpassed in size only by the giant Grass Valley and Motherload camps of California. Historically characterised by an average grade of nearly 18g/t, Bralorne’s veins exhibits exceptional structural and grade continuity with individual veins traceable for kilometres along strike and at depth. A new exploration approach by Talisker Resources has identified multi-million ounce high-grade potential both below and along strike from the historic deposits, recently returning bonanza grades as high as 995g/t. Talisker has an active 100,000m resource definition drill program focused on the conversion of this potential to resource.
The recent recognition of discrete fracture networks and associated disseminated sulphide mineralisation in the host rocks has defined a second style of mineralisation in addition to the traditional crack and seal veins mined historically. These mineralised fracture networks are observed both in the halos adjacent to larger veins and as silicified and altered fault breccias trending parallel to the high-grade veins. Early in 2021 Talisker identified an extensive shallow (<350m from surface) area of bulk tonnage mineralisation called the Charlotte Zone. The Charlotte Zone is defined by multiple sub-parallel mineralised fault structures which show classical brittle deformational zoning from a central chaotic cataclasite transitioning to mosaic and then to crackle breccia finally surrounded by stockwork of silica and sulphide veinlets. Located directly above the historic deposits, the new mineralisation style has so far been confirmed for 2km along the 30-kilometre prospective strike length of Cadwallader Break, a terrane scale suture that hosts the Bralorne gold deposits. The search for additional Charlotte Zones has moved to the forefront of Talisker’s exploration activities and is a key element in fulfilling Talisker’s vision of becoming Canada’s next Tier One explorer.
