NEW ZINC DISCOVERY AT PRAIRIE CREEK, NWT

Vancouver, British Columbia, October 21, 1999:

Canadian Zinc Corporation has discovered a new zinc showing on its 100% owned Gate claims. The 1999 exploration program has established the potential for additional zinc and silver mineralization in similar geology to that present at the company's adjacent Prairie Creek deposit.

The new discovery is a vein-type base metal bedrock occurrence. The 4.7 meter wide showing is composed of a series of parallel quartz veins. The central quartz-carbonate vein is 2 meters in width and rocks collected from talus at the base of the showing (Samples 1 & 2) carried 10.7% zinc and 820 g/t silver. One of the smaller parallel veins contains visual mineralization (Samples 3 & 4).

Sample Zn% Pb% Silver g/t Cu%
1) base of showing 10.6 16.6 820 3.5
2) base of showing 10.7 0.1 224 1.2
3) parallel vein - 31.2 306 0.1
4) parallel vein - 33.5 503 0.3

Standard multi-element assays were completed by Acme Analytical Laboratories Ltd. of Vancouver.

A geochemical soil sampling program was also carried out on the Gate claims; the results of these soil samples are being compiled and will be reported when complete. Further follow-up exploration work at the new showing is required to evaluate the full extent of mineralization.

The discovery of zinc and silver hosted in rocks similar to those present at the Prairie Creek deposit, located 10 km. downstream, clearly demonstrates the excellent regional zinc and silver potential of this underexplored area. Canadian Zinc's 100% owned Prairie Creek deposit hosts an independently calculated resource of 11.6 million tonnes of 12.5 % zinc, 10.1% lead, 161 g/t silver and 0.4% copper. Canadian Zinc's Prairie Creek mine is located northwest of Nahanni Butte in the Northwest Territories.
