Canadian Zinc Updates Mineral Resources for Prairie Creek Mine

Canadian Zinc Corp. (TSX:CZN,OTCQB:CZICF) announced an update to the mineral resources at its Prairie Creek zinc-lead-silver mine, located in Canada’s Northwest Territories. The measured and indicated tonnage has increased, as has inferred tonnage, and an underground exploration drill program is currently taking place.

Highlights of the new mineral resources include:

• Total Measured and Indicated Mineral Resource tonnages increased to 6.5 million tonnes at combined grade of approximately 20% Pb and Zn with 150 g/t Ag, details of which include:
  • an 11% increase in Main Quartz Vein tonnage to 4.1 M tonnes grading 12.4% Pb, 11.2% Zn, 199 g/t Ag;
  • an increase in Stockwork tonnage to 1.4 M tonnes grading 4.0% Pb, 7.1% Zn, 63 g/t Ag from the previous Stockwork estimate of 410,000 tonnes grading 3.7% Pb, 7.7% Zn, 69 g/t Ag;
  • a more constrained classification of Stratabound mineralization has shifted the previously reported tonnage from the Measured category to the Indicated category and decreased the tonnage by 17% to 1.1 M tonnes grading 5.4% Pb, 10.8% Zn, 55 g/t Ag.
• Total Inferred Resource tonnages increased by 13% to 7.1 M tonnes grading 9.6% Pb, 11.7% Zn, 177 g/t Ag from 6.2 M tonnes grading 11.5% Pb, 14.5% Zn, 229 g/t Ag.

In terms of the underground exploration program, the company notes:

The currently ongoing underground diamond drill program is mainly targeting MQV and STK zones with the goal of upgrading part of the Mineral Resource from Inferred to an Indicated classification. The additional Indicated Resources could then be incorporated into a new mine plan to support a longer mine life.

In order to facilitate the exploration drilling an underground rehabilitation program was carried out in the fourth quarter of 2014 by dewatering and re-installing electrical and ventilation services to the 650 metre-long decline tunnel that is located at the end of the 870m underground level.

After completion of the rehabilitation work diamond drilling was started from underground drill stations located at the end of the decline tunnel. The planned program will comprise about 6,000 metres of diamond drill coring over 21 holes on four, 50-metre sections from three existing diamond drill stations.

Drilling is presently on-going on the fifth hole of a proposed ring of six holes from the first of the three stations.
