|NorZinc Ltd. is a mine development company listed on the Toronto Stock Exchange under the symbol “NZC” and in the United States on the OTCQB under the symbol “NORZF”.
NorZinc’s key project is the Prairie Creek Mine in the Northwest Territories, which the Company intends to bring into production once financing can be arranged. Prairie Creek underwent significant development in the 1980s but never went into production. It is one of the highest zinc-equivalent grade undeveloped deposits found in the world.
the 2017 feasibility study indicates Prairie Creek has a Proven and Probable Mineral Reserve of 8.1Mt averaging 8.6% Zn, 8.1% Pb and 124 g/t Ag (3.6 oz/ton) located in proximity to three underground levels. Inferred Mineral Resources were estimated to be 7.0Mt at similar grades, which remain open-ended for future definition drilling. The mine life is 15 years based on the reserves and the inferred resources, upon being converted to reserves, should extend the mine life.
The feasibility study indicates a base case Pre-Tax NPV of $344M using an 8% discount rate with an IRR of 23.8%, and a post-tax NPV of $188M with an IRR of 18.4%, using metal price assumptions of Zn US$1.10/lb., Pb US$1.00/lb., Ag US$19.00/oz., with a foreign exchange rate of C$1.25=US$1.00. The capital costs to finish the construction and development of the Prairie Creek Mine are estimated to be $280 million.
Prairie Creek received a positive decision on the Environmental Assessment from the Mackenzie Valley Environmental Impact Review Board (“Review Board”) in December 2011 and the regulatory process for the issue to the Company a Type “A” Water Licence was completed in June 2013. NorZinc holds all the necessary significant documents for the construction, development and operation of the Prairie Creek Mine.
In 2014, NorZinc decided to commence the process to permit an all season road access to the Prairie Creek Mine to reduce the mine concentrate inventory tied up at the mine, reduce the risk of delivering concentrates to the market and delivering supplies and equipment into the mine, and to enable the consideration of alternative, more environmentally friendly, energy sources. The permitting process has now entered the regulatory phase conducted by the MVLWB that will culminate in the road permits being issued in Q3 2019.
