Vancouver, British Columbia, November 16th, 2011 - Canadian Zinc Corporation (TSX: CZN; OTCQB: CZICF) (“the Company” or “Canadian Zinc”) is pleased to report further positive results from its 2011 diamond drilling activities at the Company’s 100% owned Prairie Creek Mine in the Northwest Territories.

Additional high grade base metal values have been returned from a diamond drilling program that was testing the near surface upper levels of the main vein structure utilizing the company owned Longyear drill rig, above the National Instrument 43-101 defined mineral resource.

Main Vein Exploration

Drill holes PC-11-197 to PC-11-204 represent a continuation of a series of drill holes (PC-11-188 to 196) that were previously reported on October 3, 2011, targeted in the upper level vein area, close to surface and above the presently defined vein resource.

The vein structure was intersected and identified in each completed hole.

The new results of the vein drilling are as follows:

Bold intervals indicate weighted composite values

Most of the assays listed in the Table above are length-weighted composites which contain significantly higher grade internal values, such as in PC-11-202 which contained 20.45% Pb, 33.15% Zn, 300 gpt Ag and 0.752% Cu over 0.74 metres of core and PC-11-200A which returned values of 11.86% Pb, 23.77% Zn, 217 gpt Ag and 0.372% Cu over 2.04 metres of core.

Due to the close proximity to surface, the mineralization is highly weathered and 70–90% oxidized, which inhibited core recovery and grade determination.

A number of holes that reported two veins are being further assessed to determine their structural relationship.

The 930M mine level workings are located approximately 75 metres below these drill intercepts.

Stockwork Exploration

Drill holes PC-11-205, 207 and 208 tested an area above a previously defined zone, known as “the stockwork zone”, which contains a series of narrow high grade veins trending at oblique angles to the main vein strike.  Holes PC-11-207 and 208 reported wide moderate grade intercepts resulting from compositing a number of narrow veins together.

 Hole PC-11-205 did not report any significant assays.

Hole PC-11-206 is being drilled as part of the deep drilling campaign and had reached a depth of 1,365 metres, approximately 300 metres short of target, at the end of October when the onset of the winter season forced suspension of the 2011 drilling program.  Hole PC-11-206 will be completed in the 2012 drilling season.

2011 Drill Program Completed

The 2011 diamond drill exploration program at Prairie Creek was completed at the end of October.

In summary, 26 shallow holes were drilled with the Company’s Longyear rig, achieving 3,125 metres of coring directed at vein and stratabound targets in the immediate mine area.

The vein structure was intersected and identified in each completed hole, many of which returned high grade base metal values.

The deep drilling program in the Casket Creek area, utilizing the TM-2500 rig totalled 2,513 metres of coring in four holes including wedges and successfully intersected significant vein-type zinc and lead mineralization about 1.6 kilometres north along a projected strike extension of the geological structure that hosts the defined mineral resource at the mine and demonstrated the probable continuation of vein-type mineralization similar to that located within the main zone at the Prairie Creek Mine.

The majority of assays from the 2011 drill program have now been reported and the Company is presently awaiting assay results for two remaining two holes in the shallow drilling campaign.

 

Quality Assurance/Quality Control

The drill core samples were cut by diamond saw and securely, through chain of custody, shipped to Acme Analytical Labs in Vancouver for initial multi-element assay by ICP-ES analysis.

Further assays and analysis was completed where appropriate and standards, duplicates and blanks were inserted and included within the analysis.

Alan Taylor, P.

Geo., Chief Operating Officer & Vice President Exploration and a Director of Canadian Zinc Corporation, is responsible for the exploration program, and is a Qualified Person for the purposes of NI 43-101 and has approved this press release.

Prairie Creek Project Background

The Prairie Creek Mine is partially developed with an existing 1,000 tonne per day mill and related infrastructure.

The mineral resource at the Prairie Creek Project comprises total Measured and Indicated Resources of 5,840,329 tonnes grading 10.71% zinc, 9.90% lead, 0.326% copper, and 161 grams silver per tonne and a large Inferred Resource of 5,541,576 tonnes grading 13.53% zinc, 11.43% lead, 0.514% copper and 215 grams silver per tonne.
