VANCOUVER, Feb. 28, 2018 /CNW/ - Canadian Zinc
Corporation (TSX: CZN; OTCQB: CZICF) is pleased to report the
final results of its 2017 diamond drill exploration program on the
100% owned Tulks South copper-lead-zinc-silver-gold volcanogenic
massive sulphide ("VMS") project in central
Newfoundland.
The 2017 drill program, totaling 4,961 metres in 14 drillholes,
targeted extensions to the Boomerang-Domino VMS deposit and tested
three priority target areas located up to 2.0 km along strike of
the Boomerang-Domino deposit. The drill program successfully
extended the Boomerang mineralization 50 metres up-dip on section
3100E.
"The 2017 drilling program at the Boomerang-Domino deposit
highlights the potential to further extend the mineralization
beyond the currently defined 2007 resource estimate. There are open
areas up and down-dip of the currently defined deposit that remain
untested and open for additional mineralization", stated
Michael Vande Guchte, VP
Exploration NL for Canadian Zinc.
The Company is reviewing results of this drill program to
develop priority drill targets aimed at discovering additional
mineralized extensions to the Boomerang-Domino deposit. Highlights
of the 2017 drill program are summarized below.
Boomerang-Domino Deposit Drilling
Six drillholes, totalling 1,703 metres were complete at the
Boomerang-Domino deposit, five of which tested for 50 and 100
metres up-dip extensions of the currently defined Boomerang
mineralization. One drillhole tested for a down-dip extension to
the Boomerang mineralization.
Drillhole GA17-288 (Section 3100E) intersected 3.35 metres
grading 2.75% Zn, 2.30% Pb, 0.20% Cu, 70.9 g/t Ag and 1.5 g/t
Au and extended the Boomerang mineralization approximately 50
metres up-dip of a 2005 drillhole (GA05-46) that intersected 10.3%
Zn, 9.0% Pb, 1.0% Cu, 301.0 g/t Ag and 3.2 g/t Au over 0.40
metres.
Step-out drilling on Section 3000E (1 drillhole, 50 metres
up-dip) and 3175E (2 drillholes, 50 and 100 up-dip) intersected
variably altered and volcanic-sedimentary stratigraphy with local,
up to 1 metre thick massive pyrite intervals along the projected
Boomerang horizon. No significant base metal mineralization was
intersected.
Drillhole GA17-293 on section 3100E tested the Boomerang
stratigraphy down-dip and 100 metres southwest of a 2005 drillhole
(GA05-38) that intersected stringer base metals grading 1.9% Zn,
1.6% Pb, 0.3% Cu, 52.5 g/t Ag and 1.2 g/t Au over 4.5 metres.
GA17-293 intersected a moderately graphitic argillite horizon with
25 to 35% pyrite interpreted to represent the Boomerang trend at
depth. Anomalous mineralization of 0.75% Zn, 0.58% Pb, and 16.4
g/t Ag over 0.55 metres is associated with this horizon.
Zinc Zone Prospect
Three drillholes (1,291 metres) were completed 500 and 1500
metres along strike to the southwest of the Boomerang deposit. The
drilling targeted two, 500 metre gaps in drilling along the
projected Boomerang horizon. The drillholes intersected weak to
intensely altered felsic volcanic rocks reminiscent of the footwall
stratigraphy of the Boomerang deposit. No significant base metal
mineralization was encountered.
Telephone Hill Prospect
Three drillhole (1,131 metres) were completed at the Telephone
Hill prospect, located 2.0 km along strike and southwest of the
Boomerang deposit. The drilling targeted the down-dip potential of
two, near surface exhalative horizons intersected in 2008 drilling.
The three drillholes intersected similar quartz pyrite stockwork
style mineralization at the projected horizons 50 and 100 metres
down-dip within moderate to strongly sericite-altered felsic
volcanic rocks. No significant base metal mineralization was
encountered.
Hurricane Prospect
Two drillholes (836 metres) were completed at the Hurricane
prospect, located approximately 600 metres along strike to the
northeast of the Boomerang deposit. Drillhole GA17-295 tested the
Hurricane stratigraphy 50 metres down-dip of a 2014 drillhole,
which intersected 13.23% Zn, 8.24% Pb, 0.7% Cu, 135.8 g/t Ag and
0.67 g/t Au over 2.37 metres. GA17-295 intersected a well-developed
fault zone containing massive sulphide fragments at the projected
mineralized horizon, followed by intensely altered, pyritic felsic
volcanic stratigraphy over 60 metres with anomalous base metal
intervals, similar to that observed below the mineralized horizon
in 2014 drillhole.
The second drillhole, GA17-294 located approximately 750 metres
along strike and northeast of the Hurricane prospect tested a
zinc-in-soil anomaly. No significant base metals were
intersected.

drillhole location maps and key sections are provided on the

About Canadian Zinc
Canadian Zinc is a TSX-listed exploration and development
company trading under the symbol "CZN". The Company's key project
is the 100%-owned Prairie Creek Project, a fully permitted,
advanced-stage zinc-lead-silver property, located in the
Northwest Territories.
The Company also owns an extensive land package in central
Newfoundland that it is exploring
for zinc-lead-copper-silver-gold deposits including the South Tally
Pond project (Lemarchant deposit), Tulks South project
(Boomerang-Domino deposit) and Long
Lake (Long Lake deposit).
The Company's exploration strategy in central Newfoundland is to continue to build on its
existing polymetallic resource base with the aim of developing
either a stand-alone mine, similar to the past-producing base metal
mines at Buchans and Duck Pond, or
a number of smaller deposits that could be developed simultaneously
and processed in a central milling facility.
Quality Assurance and Quality Control
Drillhole intervals are core length with true thickness
estimated to be 75-100% of core length. Samples were sawn from
NQ-sized core with half core sections sealed in plastic bags and
transported by Canadian Zinc personnel to Eastern Analytical Labs
in Springdale, Newfoundland.
Samples were analyzed for Cu, Pb, Zn, Ag and Au at Eastern
Analytical Labs from the sawn NQ-sized half core sections. Data
quality is monitored through the insertion of control samples
consisting of one prepared base and precious metal standard and one
blank sample for every 20 samples of drill core. All control
samples conformed to the accepted contained grades of base and
precious metals. Select samples pulps were shipped to ALS Minerals
in North Vancouver, BC for
33-element ICP analysis for further check assays of significant
base and precious metal bearing samples. Historical results were
obtained from published reports and news releases available in the
public domain.
