Drill Hole Assay Intervals Including 18.35% Zinc Over 108 Feet and 7.81% Zinc Over 70 Feet Found in Historic Data
November 25 2015 - 10:48AM
Nevada Zinc Corporation ("Nevada Zinc" or the "Company")
(TSX-V:NZN) is pleased to announce that it has secured significant
exploration data from exploration and mining work carried out at
its recently acquired Mountain View Mine ("MVM") and the
surrounding area, in some cases dating back more than 70 years. The
recently acquired data which came from two separate sources
significantly enhances the data available to-date on the MVM
property and expands the limit of the known mineralization on the
Company's Lone Mountain project. The files include partial diamond
drill core assay results for 37 of 41 diamond drill holes completed
on or near the recently acquired MVM property.
President and CEO, Bruce Durham commented on the acquisition of
the historic data, "It always increases our understanding of a
project when we can indirectly have the assistance of the previous
operators. There are details in historic maps and reports that are
of great assistance in the planning of our future exploration
programs. In this case we have old drill results, maps of
underground workings, geological maps of some underground workings
as well as old smelter settlement records for ore shipments, all of
which will be very helpful in moving our Lone Mountain project
forward."
Highlights
- Records indicate that there were 41 generally very shallow
surface drill holes completed during 1944 and 1945 to test for near
surface zinc mineralization in the vicinity of the MVM mine
workings and extending to the west to the general vicinity of the
up-dip projection of the Company's Discovery Zone of
mineralization.
- 33 holes are reported to have been drilled at a variety of
angles, dips and and to various lengths. Virtually all of these
holes intersected significant intervals of zinc
mineralization.
- 28 holes were drilled on or in close proximity to the MVM
property and stretch across the projected strike length of the main
zone from the west boundary to the east boundary of the MVM
property, a distance of 180 metres.
- None of these diamond drill holes are reported to have tested
the main zones of zinc mineralization more than 250 feet below
surface and most of the holes intersected the mineralization at
depths of less than 100 feet.
Summary of Historic Information
- The Company is working to ascertain the actual location of the
holes so they can be included in an updated database of hole
locations and drill hole intercepts. The holes can then be updated
onto a longitudinal section in the plane of the main Discovery Zone
of mineralization.
- The most easterly hole drilled on the main zone reported
shallow mineralization near the east boundary of the MVM property
with intersections of 46 ft averaging 4.63% zinc and 17 feet
averaging 8.8% zinc in the interval between 79 feet and 195 feet.
It is not known if additional intervals were analyzed. No drilling
is reported to the east of the MVM property.
- The diamond drill hole assay intervals are all shallow and all
of the drill holes on the MVM property are drilled at elevations of
100 feet above the collars of the Company's drilling on its
Discovery Zone of zinc and lead mineralization. No diamond drill
holes tested the main zone of zinc mineralization at depths at
which the Company has intersected broad zones of high grade zinc
mineralization. One of the deepest intersections in the historic
program near the west boundary of the MVM property, DDH -36
intersected two zones of mineralization: 31 feet grading 7.42% zinc
and 26 feet grading 4.46% zinc. The bottom of the deeper section is
at 226 feet below the collar of the hole.
- The Company will provide further commentary and results on the
data review as the evaluation of the data progresses. What can be
said is that the work appears to have been carried out in a
detailed and methodical manner.
- The data obtained is all more than 60 years old and is
therefore historic, incomplete, the assay methods are not known. No
QA/QC is known to have been completed and therefore the information
contained in this release must be considered to be historic in
nature under NI 43-101 and therefore should not be relied upon. The
Company does, however, consider the data to be of significance and
of value for future work programs on the property.
- Initial indications are that core recovery in the mineralized
zones was very poor in some cases (not uncommon given drilling
techniques 70 years ago).

The drill
core assay results above are from 1944 and 1945 as summarized in a
table in 1951-1952 and as such predate NI-43-101 standards for
disclosure for mineral projects. The data is therefore to be
considered historic, it is incomplete, and the assay methods
are not known. |
|
|
|
|
|
No QA/QC is
known to have been completed and therefore the information
contained in this release must be considered to be historic in
nature under NI 43-101 and therefore should not be relied upon.
The drill collar locations and azimuths are being verified to
help determine the quality of the historical work. True widths have
not and cannot be calculated for the intervals in the table above.
All data is in feet: to convert to metres multiply by
0.3048. |

The Mountain View Mine Property
Little information was readily available on the operations at
the historic Mountain View Mine at the time the Company purchased
the MVM property. In a Nevada State report by Roberts, R.J.,
Montgomery, K.M., and Lehner, R.E., (1967) and titled Geology and
Mineral Resources of Eureka County, Nevada, Nevada Bureau of Mines
and Geology, Bull. 64, the following is indicated:
Production years were from 1942-1964 and production totalled
4,952,627 lb of zinc, 649,579 lb of lead, 4,040 oz of silver and
600 lb of copper (no data provided or available for 1950).
Roberts et al (1967) reported the first claims were located in
the area in 1920 for zinc. Production was small until 1942 when
high grade zinc carbonate was discovered on the Mountain View
claim. An underground mine was established with levels on the
44-foot and 82-foot levels. Production in 1942-1943 totalled 2,284
short tons grading 28.8% zinc and 4% lead. Production to 1964
amounted to 4,952,627 lb. of zinc, 649,579 lb. of lead, 4,040 oz of
silver and 600 lb of copper. The mineralogy of the ore was reported
to be smithsonite, zincite, hydrozincite and cerussite, malachite,
and azurite. It was reported that small amounts of sulphide were
present locally, principally, sphalerite, galena, chalcopyrite, and
pyrite. A small drill program was reported to have been completed
in areas proximal to the MVM property which indicated the presence
of additional mineralization. Mineralization is located within
brecciated Devils Gate Limestone and is thought to be structurally
controlled, perhaps at the intersection of two fault systems
(Roberts et al.).
It is not known if any mining or exploration has been completed
on the MVM property since 1964.
About The Lone Mountain Project
The Lone Mountain project (the "Property") which is 100% owned
by the Company is comprised of 218 claims covering approximately
4,000 acres and is subject to certain terms as per the underlying
lease agreements disclosed on SEDAR (press release June 24, 2014
and various other filings including the Company's MD&A's filed
on SEDAR).
The Property 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 Property
now includes the Mountain View Mine.
Bruce Durham, P.Geo, is a qualified person as that term is
defined by National Instrument 43-101 on behalf of the Company and
has approved the scientific and technical content contained in this
