VANCOUVER
,
May 14, 2018
/CNW/ -
Callinex Mines Inc.
(the "Company" or "Callinex") (TSX-V: CNX; OTCQX: CLLXF) is pleased to
announce results from an independent initial Preliminary Economic Assessment ("PEA") on the Company's
100% owned
Nash Creek
and
Superjack Projects
located in the Bathurst Mining District of
New Brunswick, Canada
(See
Figure 1
and
Figure 2
).
The initial PEA outlines a 10-year, 3,900 tpd open-pit mining operation with a Dense Media Separation ("DMS") plant and 1,950 tpd
conventional flotation process facility at the Nash Creek Project (the "Project").
The mine plan generates a strong economic return with a
pre-tax internal rate of return ("IRR") of a 34.1% (25.2% post-tax) and a pre-tax Net Present Value ("NPV") at an 8% discount
rate of
C$230 million
(
C$128 million
post-tax)
based on pre-production capital costs of
C$168 million
and a zinc price of
US$1.25
/lb (
See
Tables
1 and 2). The Company believes there is a clear opportunity to significantly enhance the project's economics with additional exploration that
allows for higher grade material to be scheduled earlier in the mine plan (See
Figure 3
).
Max Porterfield
, President and CEO, stated, "We are very pleased with the results of this initial PEA that outlines the potential for a new zinc mine
at our Nash Creek Project. The results of this PEA, combined with close proximity to infrastructure and a district-scale land package, represents a
highly attractive scenario for Callinex shareholders."

Cautionary Note on PEA.
The PEA is preliminary in nature and it includes Inferred Mineral Resources that are considered too speculative
geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no
certainty that the PEA will be realized.
The Nash Creek Deposit is open for expansion in several directions with relatively few drill holes located outside of the Mineral Resource area.
The 2017 drilling campaign on the Nash Creek Deposit, the first to ever be completed by the Company, led to a 74% increase in
Indicated Mineral Resource zinc equivalent ("Zn Eq.") pounds and a 385% increase in Inferred Mineral Resource zinc equivalent
pounds
(
See News Release dated
April 16, 2018
). Additionally, the Project encompasses several untested high-grade mineral occurrences over a
highly prospective 20 km long trend. The Company plans to commence permitting while aggressively advancing exploration opportunities within
this underexplored 150 km
²
district-scale land package.
The
Nash Creek
and Superjack Projects benefit from world-class infrastructure within close proximity. The Nash Creek Deposit is located
approximately 1 km from Provincial Highway 11 and a 230 Kv high-voltage transmission lines and only 25 km by road to Glencore's Brunswick
Smelter, deep water port, railway and power plant near the town of
Belledune
(See
Figure 1
and
Figure 2
).
The Superjack Project is located 90 km by highway from the Company's Nash Creek Project and 15 km southwest of the Brunswick No. 12
Mine, which was previously the largest underground mine in the world (See
Figure 1
). Mineralization at the Superjack Project is hosted within a
similar geological environment as the 'supergiant' Brunswick No. 12 Mine and Trevali's nearby Caribou Mine.
Callinex anticipates that development of the Nash Creek Project will provide a major economic benefit to the community of
Lorne
and additional
nearby communities within
New Brunswick
. The PEA assumes that development of the project would create approximately 225 full-time jobs and
contribute nearly
$200 million
in direct tax benefits.
The PEA was prepared under the supervision of
Eugene Puritch
, P. Eng., FEC, CET of P&E Mining Consultants Inc. the technical report will be
filed on SEDAR within 45 days of this news release.
Opportunities and Exploration Potential
The Company's management team is very encouraged about the strong economic results generated from its initial PEA and the opportunities for
further improvement with additional exploration, especially considering that only limited drilling has occurred outside of the Mineral Resource area.
Notable opportunities for further improvement include:
Exploration or acquisition activities resulting in the addition of higher-grade material after year one of the mine plan which could have
potential to significantly increase the IRR and NPV
8%
(See
Figure 3
);
Expand the 10-year mine life with additional exploration success at the Nash Creek Deposit, which is open for expansion, to increase the
NPV
8%
and evaluate increasing process plant throughput with potential to lower unit costs and increase production volumes; and
Potential for new discoveries within a 150 km
2
land package where a primary north-south corridor has several high-grade mineral
occurrences up to 19% Pb+Zn at surface with very limited historic drilling.

Mining and Processing Method
The PEA assumes a conventional truck and excavator open-pit mining operation at an average annual process plant production rate of 1,425,000
tonnes per annum over a mine life of approximately 10 years. Mining operations will reach an annual average total material movement of 10 million
tonnes using
11.5 m
3
diesel hydraulic excavators, 90 tonne haulage trucks, and track mounted diesel powered drill rigs with up to 200 mm
diameter blastholes drilled on 5 and 10 metre height benches.
The mined material will be processed at a new 3,950 tonne per day dense media plant and a 1,950 day tonne per day grinding and flotation plant
located on the Project site. Two concentrates will be produced; zinc-silver and lead-silver. It is anticipated that lead concentrates could be
processed at the nearby Belledune Smelter and zinc concentrates at
Valleyfield, QC
. The zinc concentrates also have potential to be processed
overseas via the deep water port from
Belledune
although this alternate option was outside the scope of the PEA and was not investigated. A
review of metallurgical test work has not identified any deleterious elements that would impact the marketability of the zinc and lead concentrates,
which are considered of good quality.

Project Infrastructure
The Project will benefit from infrastructure, services and skilled labour available in the Bathurst Mining Camp. The Nash Creek Project site is
located approximately 50 km northwest of the city of
Bathurst
and is accessible year-round from paved Provincial Highway 11 and a 1 km paved
road. Project site infrastructure is anticipated to include:
Plant site and haul roads;
Administration buildings and assay lab;
Mine maintenance shop, warehouse and fuel storage facilities;
Fresh water supply and sewage treatment; and
Lined tailings storage area.
The proposed Nash Creek Project mill and process plant site is ideally located on the access road to the open pit and on private land owned by
Callinex. The proposed processing plant site is located on a relatively flat area adjacent to the open pit. A small creek valley to the west of the
open pit provides a suitable site for a dammed tailings management facility for the first 4 years of mine life. Thereafter, tailings will be deposited into
the first small pit area to be mined out. Power to the site will be supplied by a 1 km transmission line connecting to the nearby 230 kV provincial
grid.
Environmental, Permitting and Taxes
The PEA envisages potential to create approximately 225 jobs if the project is advanced into production. The project could have a major impact
within the surrounding communities of
Lorne
and
Belledune
, where there are limited number of economic opportunities resulting in a unemployment
rate exceeding 20%. The nearby cities of
Bathurst
and Cambellton located within 50 km to the Project also have higher unemployment rates of
approximately 11%. In addition to the potential for direct job creation, the PEA outlines gross taxes and royalty payable to the Province of
New
Brunswick
of approximately
$130 million
and approximately
$64 million
to the Government of
Canada
(See Table 6).
The Nash Creek Project will be subject to federal, provincial and local regulatory requirements. The principal provincial legislation related to the
approval of mining projects and environmental impact assessment (EIA) and are the New Brunswick Mining Act and General Regulation 86-98 of
The Clean Environment Act and EIA Regulation 87-83, and Water Quality Regulation 82-126. Relevant key federal legislation includes the
Canadian Environmental Assessment Act, Fisheries Act and Metal Mining Effluent Regulations. The New Brunswick Department Energy and
Resource Development has provided a concise guide to the mine approval process.
The relatively low sulphide content of the
Nash Creek
mineralization is anticipated to have low waste rock ARD potential. Additionally, identifiable
ARD material will be placed in the mined out open pits at the end of the Project life.

Conceptual Toll Milling Scenario
P&E investigated the concept of transporting the mined mineralized material with DMS upgrading to a hypothetical toll milling facility within the
Bathurst Mining District located 100 km from the Nash Creek Project. Transport costs of
C$15
/tonne and toll processing costs of
C$24
/tonne
were assumed.
This scenario provided robust economic return on capital with a pre-tax IRR of 46.9% (32.3% post-tax)
and a pre-tax
NPV
8%
of
C$125 million
(
C$69 million
post-tax) with a pre-production capital cost of
$62.2M
Mineral Resource Estimates Incorporated in PEA
The PEA mine plans assumes that 14.4 million tonnes of diluted mineralized material grading 3.1% Zn Eq. (2.9% Zn, 0.6% Pb and 20.3 g/t Ag) is
delivered to the DMS plant. The table below outlines the total Indicated and Inferred Mineral Resources (
See News Release dated
April 16,
2018
), including those that were not included within the mine plan.
