Nevada Zinc Corporation (“Nevada Zinc” or the “Company”)
(TSX-V:NZN) is pleased to report assay results for 10 reverse
circulation drill holes from its ongoing drill program on the
Company’s Mountain View Mine which is part of the Company’s
highly prospective Lone Mountain zinc project (the “Project”)
located near Eureka, Nevada. The current drilling program is part
of a work program designed to evaluate the potential of the Project
to host a near surface zinc-lead resource that could potentially be
mined using low cost open pit mining techniques. All 12 holes
reported to date from the Mountain View Mine have intersected near
surface zinc-lead mineralization.
President and CEO, Bruce Durham commented,
“Drilling at the Mountain View Mine continues to give us confidence
that zinc-lead mineralization extends well beyond the limits of the
historic mining of the Mountain View Mine from the 1940’s to the
1960’s. Three of the ten holes intersected what appear to be old
drifts or stopes and yet significant mineralization was intersected
in the walls of the historic mine openings indicating that mining
was focused on only very high grade mineralization. Some of this
mineralization is essentially exposed at surface and all of the
mineralizaiton we are intersecting is very shallow so we feel this
is an excellent project to be evaluated as a potential low cost
open pit target. Zinc fundamentals remain very strong and the
significant reduction in mine supply should start to be reflected
in the zinc price as inventories continue to decline.”
Highlights
Drill Hole LM-16-48 intersected high
grade zinc-lead mineralization at a vertical depth of only 19.81
metres (65 ft.). A 15.24 metre (50 ft.) interval from 19.81 to
35.05 metres (50-115 ft.) averaged 11.89% zinc and 3.74% lead
(15.63% zinc + lead).
Additional assay results will be available in
the coming weeks as the current drill program continues.
The drill hole assay data reported to date shows
zinc-lead mineralization essentially extending from the west
boundary of the Mountain View Mine (see accompanying Plan Map) to
beyond the mid-point of the Mountain View Mine property a distance
of more than 110 metres.
Two drill holes, LM-16-43 and 44 collared in
zinc-lead mineralization under shallow overburden.
Three drill holes, LM-16-40, LM-16-44 and
LM-16-46 appear to have intersected shallow historic mine openings
and therefore are missing the high grade portion of the zinc-lead
mineralization that would have been mined at those locations.
The zinc-lead target tested in these short drill
holes is one of two or more zinc-lead zones in the area near some
historic small scale mining at the Mountain View Mine that occurred
some 50 years ago. That mining was apparently focused on narrow
high grade zinc rich fractures with the material hand sorted and
direct shipped to a smelter for processing.
Additional drill holes are planned for Mountain
View Mine and other nearby targets as part of a program to
delineate near surface zinc mineralization that could potentially
be mined using low unit cost open pit mining methods.

Notes: Hole LM-16-40 includes a 7.6 metre
interval from 68.58 metres to 76.2 metres at zero grade due to lack
of sample recovery (historic stope). Hole LM-16-44; above 24.38
metres there is a 12.2 metre interval with no sample recovery
(historic stope). Hole 16-46 includes 6.38 metre interval at zero
grade due to a lack of sample recovery (historic stope) at 18
metres. All intervals are down the hole distances and true
thickness could not be determined at this point in the exploration
program.
Sample Preparation and Quality
Control
Supervision and organization of reverse
circulation drilling chip samples was undertaken by Nevada Zinc
personnel. Samples were collected at 1.52 metre intervals
from a rotating wet splitter assembly attached to the drill rig.
Chip tray samples were collected from the reject side of the wet
splitter. The splitter was adjusted to produce 4.5-9.0 kg of
sample. Samples were collected from the drill in cloth bags
by employees of New Frontier Drilling under the Company’s
supervision. Samples were catalogued by Nevada Zinc
geologists and stored in a secure location. Certified
reference standards were placed in the sample stream of each drill
hole at random intervals. Blank material was also inserted at
random intervals.
Assay Techniques
Preparation of the samples was done at the ALS
Chemex Elko, NV facility. A 250 gram master pulp was taken,
then splits were sent to ALS’s North Vancouver, BC facility or
their Reno, NV facility. A 48 element package using a 4 acid
digestion with ICP-AES and ICP-MS completed on all samples. For
lead and zinc values exceeding the limits of the 48 element package
(1% zinc or lead), the procedure was to use a 4 acid digestion with
ICP-AES or AAS finish (ore grade analysis). In the case of
values exceeding the limits of the ore grade analysis (30% zinc,
20% lead), the procedure was to use specialized titration
methods.
Laboratory QA/QC
Quality control samples from the lab include
numerous control blanks, duplicates and standards. Reference
standards used include OREAS-133b, OREAS-134b, OGGeo08, and
CZN-4. No significant issues were noted with analytical
accuracy or precision.
ALS Chemex’s Reno, Elko, and North Vancouver
locations have ISO/IEC 17025:2005 accreditation.

Zinc Information
The International Zinc Association website;
(www.zinc.org) is a good source of information on zinc and its
varied uses.
Teck, the world’s third largest zinc miner
provided a review of the zinc market in its shareholder day
presentation (March 30, 2016):
http://www.teck.com/investors/presentations-webcasts/teck-s-investor-and-analyst-day---march-30
Slides111-117. The slides clearly depict a looming significant zinc
deficit for many years to come due to continued growing demand for
zinc offset by mine closures and a lack of new investment.
The current global weighted average mine grade
for zinc operations, both open pit and underground, is now below 5%
zinc (see Teck ppt).
Additional zinc information is also available on
the Nevada Zinc website (www.nevadazinc.com).
About Nevada Zinc
Nevada Zinc is a discovery driven mineral
exploration company with a proven management team focussed on
identifying unique opportunities in mineral exploration that can
provide significant value to its shareholders. The Company’s
existing zinc and gold projects are located in Nevada and Yukon,
respectively.
The Lone Mountain Project
While the Company maintains its highly
prospective Yukon gold properties and continues to advance them,
the current focus of the Company is the exploration and advancement
of the Project comprised of 224 claims covering approximately 4,000
acres near Eureka, Nevada.
The Project is located in east-central Nevada
and is easily accessible via paved and gravel roads northwesterly
from Eureka where all essential services are available. The Project
now includes the historic zinc mine known as the Mountain View
Mine.
