NorZinc launches silver-focussed exploration drill program and resource estimate update at Prairie Creek

5 October 2020

NorZinc Ltd. is pleased to announce, as part of its Mine Enhancement program, the launch of a new surface exploration drill program and resource updates at the Prairie Creek Mine.

  • The drill program will be focussed on potential reserve expansion in the area immediately to the north of the current reserve envelope, adjacent to the last hole drilled at Prairie Creek in 2015 (Hole PCU-15-72) that returned several intercepts, including: 
  1. a vein intercept of 7.5m true width of 247 g/t Ag (7.2 oz/ton), 33.7% Zn, 17.8%; and 
  2. a stockwork intercept of 3.7m true width of 257g/t Ag (7.5oz/ton), 29.3% Zn and 18.7% Pb[1]
  • The Company has engaged Cube Consulting Pty Ltd. to review existing drill data and prepare an updated resource estimate following completion of the surface drill program.  
Prairie Creek Silver Reserves and Resources 
The Prairie Creek Mine was originally developed in the 1980s as the Cadillac Silver Mine by the Hunt Brothers. In subsequent years, the focus has been on the zinc/lead values due to the extremely high grades of those combined metals. However, recent increases in silver prices, combined with the existence of high silver grade zones at the Mine, have resulted in a return to the focus on silver. Current resources[2] contain 38.1 million ounces (Mozs) of silver in the measured and indicated category and 37.6 Mozs in the inferred category.  Current reserves[2], which are included in the above resources, contain 32.2 Mozs of silver.
