VANCOUVER, BC -- November 30, 2016 -- InvestorsHub NewsWire --
Copper North Mining Corp. ("Copper North" or the "Company")
(TSX
VENTURE: COL) is pleased to announce the Filing of the
Preliminary Economic Assessment Report on SEDAR. The results of the
PEA report were news released Oct 12, 2016. The PEA Report
evaluates the recovery of copper, gold and silver at the Company's
Carmacks Copper-Gold-Silver project. The Carmacks Project is
located in south central Yukon within the southern end of the
copper-gold-silver Dawson District.
Dr. Harlan Meade, President and CEO of Copper North, states:
"The use of agitated tank leaching provides for high recoveries of
gold alongside the leaching of copper. The application of agitated
tank leach technology has reduced operating and environmental risk,
compared to the previously proposed heap leach of copper. The
agitated tank leach provides for rapid leaching of the copper
followed by gold-silver and improved recoveries. The C1 cost of
copper production is US$1.08/lb1 after deduction of
byproduct gold and silver credits; all in sustaining cost is
US$1.16/lb2. The production costs place Carmacks Project
in the lower decile of the cost curve of projects in the
development pipeline. The PEA indicates that the re-engineering of
Carmacks Project has much improved the Carmacks Project; it has
also highlighted the potential for expansion of mineral resources.
Management is planning on-going engineering of the Carmacks Project
to achieve Prefeasibility standard report and pursue capex and opex
reduction opportunities and expansion of mine life by adding
another 3 years of new oxide mineral resources that were defined in
the 2015 exploration program and the NI 43-101 mineral resources
initially reported January 25, 2016."
Project Summary
The Carmacks Project is an open pit operation for processing of
oxide copper, gold and silver mineralization. The re-engineered
project in the New PEA utilizes agitated tank leach processing of
copper oxide mineralization to produce cathode copper, followed by
agitated tank leach cyanidation and carbon-in-leach (CIL)
processing for recovery of gold and silver in doré. Tailings are
filtered for dry-stacked storage. Drilling in 2015 identified a
substantial sulphide mineral resource that warrants further
evaluation of the potential for mining and processing the sulphide
mineralization.
Exploration has also indicated additional oxide mineral
resources for which management believes further drilling is
warranted for both oxide and sulphide mineralization to expand
mineral resources and extend mine life.
More detailed information on the Project is in the Oct 12, 2014
news release and the PEA filed on SEDAR November 25, 2016.
Preliminary Economic Assessment
The New PEA was prepared in accordance with National Instrument
43-101 Standards of Disclosure for Mineral Projects ("NI
43-101") by JDS Energy and Mining Inc., and a number of other
consultants. The New PEA supersedes the Company's previous
technical reports in respect of the Carmacks Project. The New PEA
builds upon previous engineering studies on the Carmacks Project
and additional work completed during the past 28 months. Initial
work was focused on additional metallurgical test work supervised
by Dr. Morris Beattie P.Eng. and Dr. David Dreisinger P.Eng. The
expanded resource estimate was completed by Dr. Gilles Arseneau,
P.Geo. of Arseneau Consulting Services Inc.; designs of the waste
rock storage area and tailings management area were developed by
Fiona Esford, P.Eng. and David Anstey, P.Eng. of Golder Associates
Ltd.; and the mining plan was developed by Michael Hester, FAusIMM
of Independent Mining Consultants Inc. All of the foregoing
individuals are "Qualified Persons" as defined under NI 43-101.
Project Economics Highlights
The base case metal price in the PEA is US$2.50/lb copper which
is near the median of current medium to long term analyst forecasts
for copper. Gold was applied at US$1300/oz and silver at
US$17.50/oz. With the recent rapid increase in copper price a
Consensus Price model is included in the table with copper price at
US$2.75/lb and the gold and silver price remained the same as in
the Base case. The Consensus Price reflects price forecasts for
2017. The PEA uses an exchange rate of CAD$1.00 equals US$0.78
(US$1.00 equals CAD$1.28). Costing is in Canadian dollars.
Copper recovery is 85.5% and gold recovery is 84.4%; additional
metallurgical test work is warranted to improve current 9.4%
recovery for silver.

Sensitivity
The pre-tax price sensitivity for copper and gold provides a
range of values for Net Present Value, Internal Rate of Return and
Payback of capital. The project economics would be much improved in
the event of a 10 to 20% increase in copper and gold pricing and
extension of mine life. Extension of mine life would also have a
significant positive impact on the project economics and is a key
objective for project improvement.

This technical report contains forward-looking information
regarding projected mine production rates, construction schedules
and forecasts of resulting cash flows as part of this study. The
mill head grades are based on sufficient sampling that is
reasonably expected to be representative of the realized grades
from actual mining operations. Factors such as the ability to
obtain permits to construct and operate a mine, or to obtain major
equipment or skilled labour on a timely basis, to achieve the
assumed mine production rates at the assumed grades, may cause
actual results to differ materially from those presented in this
economic analysis.
Project Opportunities and Risks
In the re-engineering of the Carmacks Project and the
preparation of the New PEA, the Company has identified a number of
opportunities for improving project economics. Key to overall
project economics is the extension of mine life and capital
reductions, and positioning the project to achieve greater
efficiencies in the event of improved metal prices.
Recovery and Operation Improvements
- Process improvements include a modest metallurgical test
program to optimize the balance between copper and gold-silver
recoveries; particularly the optimal leach temperature for copper
and recovery of silver.
- Alternative improved solid-liquid separation of copper leach
circuit and equipment.
- Further evaluation of reagent efficiency and purchase.
- Mine and plant construction efficiency and timelines.
- Global sourcing of used equipment for some parts of
operations.
- Evaluation of processing sulphide mineral resource at Carmacks,
for future mine extension.
Next Steps
The Company intends to complete geotechnical and hydrogeology
study for the dry stacked tailings management area needed for
completion of environmental management planning for resumption of
permitting of the project. A modest metallurgical and process study
will be undertaken to improve and upgrade the PEA. Additional
drilling is planned to expand the Measured and Indicated mineral
resources that were reported in the January 2016 mineral resource
prepared in accordance with NI 43-101, and undertake mine planning
of the new oxide mineral resources for inclusion into an expanded
mine plan.
