Highland Copper Company Inc. (TSXV: HI; OTCQB: HDRSF)
(“
Highland” or the “
Company”) is
pleased to announce the results of an updated feasibility study
(the “
Feasibility Study”) for its 100%-owned
Copperwood project located in the Western Upper Peninsula of
Michigan, U.S.A. (the “
Copperwood Project” or the
“
Project”).
Key Highlights
-
Copperwood provides significant leverage to copper
price. The updated Copperwood Feasibility Study, done in
the high-cost environment of 2022, still has a robust 17.6% IRR at
a copper price of $4.02 per pound. The average yearly production of
approximately 30,000 tonnes of copper provides good exposure to
copper price increases.
-
The Copperwood Project is now fully permitted. The
Copperwood Project holds all key Michigan State permits required to
proceed with site construction and operation. The detailed design
for stream and wetland mitigation work as per permit conditions has
been completed. Importantly, an alternative process water solution
incorporated in the Feasibility Study Update eliminates the need
for the Section 10 Water Intake permit.
-
Measured & Indicated tonnes increased by 10% and
Inferred tonnes increased by 54%. With updated metal price
assumptions and a modified reporting cut-off, a significant
increase in resource tonnes has been reflected in the 2023 mineral
resource estimate relative to the 2018 mineral resource (Copperwood
Feasibility Study dated effective June 14, 2018, posted to SEDAR on
July 31, 2018).
-
Considerable opportunities remain to improve the project’s
economic return. The applicability of ore sorting to
remove waste and low-grade material has been tested with positive
results. The potential economic impact will be assessed and
incorporated in the detailed engineering phase or in subsequent
studies. Additional metallurgical test work will also be performed
to determine the potential to reduce reagent consumption.
-
Early works and site preparation are planned at Copperwood
for 2023. Some site preparation work will need to be
completed to meet permit obligations. Advancing towards site
readiness and starting the initial phase of detailed engineering
will help support a construction decision. A portion of these
expenditures will net against the initial capital estimate.
“We are happy to introduce Copperwood as one of
very few fully permitted copper projects in the US. The economic
return at spot copper price is robust and the project is highly
sensitive to copper price changes. It will be exciting to start
site works during 2023 as we advance discussions on funding of our
Copperwood project.” said Denis Miville-Deschênes, President and
CEO of Highland Copper.

Copperwood Next Steps
The following key steps will be taken to
facilitate a construction decision at Copperwood:
-
Early Site Works: certain early site work must be
completed to meet permit obligations under the Wetlands and Streams
Permit. The Project will complete permitted impacts, which include
site clearing and grubbing, during the summer of 2023 .
-
Environmental Mitigation: work will begin on
environmental mitigation commitments under the Wetland and Streams
Permit which must be completed within one year of on-site impact.
The impact and mitigation costs are included in the Feasibility
Study.
-
Detailed Engineering: detailed engineering will be
initiated, particularly for long-lead items and any aspects of the
project being included in early site works.
-
Construction Finance Plan: capital markets will
continue to be assessed and Highland will develop a broad financing
plan for the construction of the Copperwood Project.
Updated Copperwood Feasibility
Study
Copperwood Project
The Copperwood Project property is located in
the western Upper Peninsula of Michigan, approximately 22.5 km
to the north of Wakefield by road. The project area is at the south
edge of the Keweenaw Copper province and underlain by clastic
sediments of the Oronto Group, including the Copper Harbor,
Nonesuch and Freda Formations.
Both the Copperwood and satellite deposits are
hosted by the limbs of the northwest dipping Presque Isle Syncline
within the Nonesuch Formation. The Nonesuch Formation contains two
mineralized sequences, one located at the base, the Lower Copper
Bearing Sequence (“LCBS”) and a stratigraphically
higher one, the Upper Copper Bearing Sequence
(“UCBS”), separated by poorly mineralized
sediments with a variable thickness of 0.5 m to
6.0 m.
Chalcocite is the only copper sulfide bearing
mineral, occurring principally as disseminations within shale and
siltstone. Individual disseminated grains of chalcocite are most
commonly very fine grain, approximately 5 to 50 microns in
diameter. The Copperwood deposit is relatively subhorizontal with a
thickness that varies from 1.6 m to 3.7 m.
Mineral Resources
The Mineral Resource estimate for the Copperwood
Project disclosed in this press release is based on the same
technical data disclosed in the 2018 feasibility study, with
updated metal price assumptions and a modified reporting cut-off.
No additional drilling has been completed at the Copperwood Project
since the 2018 feasibility study. The resource estimate was
prepared in accordance with CIM Definition Standards on Mineral
Resources and Reserves (adopted May 10, 2014) and is reported
in accordance with National Instrument 43-101
(“NI 43-101”) Standards of Disclosure for
Mineral Projects. Classification, or assigning a level of
confidence to Mineral Resources, has been undertaken with strict
adherence to CIM Definition Standards on Mineral Resources and
Reserves.
The mineral estimate was prepared under the
supervision of James Purchase, P. Geo. of GMSI, an independent
Qualified Person as defined in NI 43-101.
The Copperwood deposit’s total Measured and
Indicated (“M&I”) Mineral Resources are estimated at
54.2 Mt grading an average 1.49% Cu and
3.6 g/t Ag containing 1.78 B lb Cu and
6.3 M oz Ag using a lower cut-off grade of
0.9% Cu for the LCBS and UCBS combined.
The Deposit’s Inferred Mineral Resources are
reported at 79.1 M t grading 1.09% Cu and
3.5 g/t Ag containing 1.9 B lb of copper and
9.0 Moz of silver using a lower cut-off grade of 0.9% Cu
for the LCBS and UCBS combined.

Notes on Mineral Resources:
1) Mineral Resources are reported
using a copper price of $4.00/lb and a silver price of
$25/oz.2) A payable rate of 96.5% for copper and
90% for silver was assumed.3) The Copperwood
Feasibility Study reported metallurgical testing with recovery of
86% for copper and 73.5% for silver.4) Cut-off
grade of 0.9% copper was used, based on an underground “room and
pillar” mining scenario.5) Operating costs are
based on a processing plant located at the Copperwood
site.6) Assuming a long-term copper price of
$4.00/lb, a sliding scale 5.5% Net Smelter Return (“NSR”) royalty
on the Copperwood Project is payable to leaseholders.
7) Measured, Indicated and Inferred Mineral
Resources have a drill hole spacing of 175 m, 250 m and
350 m, respectively.8) A minimum mining
thickness of 2m was applied. No additional unplanned mining
dilution and mining loss were considered for the Mineral
Resources.9) Rock bulk densities are based on rock
types.10) Classification of Mineral Resources
conforms to CIM Definition Standards
(2014).11) The Qualified Person for the estimate

Notes on Mineral Reserve
Estimates1) The Mineral Reserves were estimated
using the Canadian Institute of Mining, Metallurgy and Petroleum
(CIM) Estimation of Mineral Resources & Mineral Reserves Best
Practice Guidelines (Nov 29, 2019) and CIM Definition
Standards for Mineral Resources and Reserves, (May 10,
2014).2) Mineral Reserves are estimated at a
cut-off grade of 1% Cu. The cut-off will vary depending on the
economic context and the operating
parameters.3) Mineral Reserves are estimated using
a long-term copper price of $4.00/lb and a silver price of
$25.00/oz.4) Assuming a long-term copper price
$4.00/lb, a sliding scale 4.0% NSR royalty on the Copperwood
Project is payable to leaseholders. A 1.5% NSR royalty on the
Copperwood Project payable to Osisko Gold Royalties Ltd. This also
includes an additional 11.5% silver mineral royalty payable to
Osisko Stream Royalties.5) Mineral Reserves are
estimated using an ore loss of 3%, a dilution of 0.1 m for the
floor and a 0.25 m for the back of the stope and the
development.6) The economic viability of the
mineral reserve has been demonstrated.7) A minimum
mining height of 2.1 m was used.8) The copper
recovery was estimated at 86%.9) The Qualified
Person for the estimate is Carl Michaud, P. Eng., Underground
Engineering Manager for GMSI. The estimate has an effective date of
May 25, 202210) The numbers may not sum due
to rounding; rounding followed the recommendations in
NI 43-101.11) The geotechnical parameters of
the previous technical report from June 2018 were used in this
Feasibility Study update.
Mine Operations and
Services
It is proposed to mine the deposit using a
room-and-pillar mining method. Based on the orebody thickness, two
highly mechanized methods, conventional drill and blast and
continuous mining will be used. The drill and blast approach is
used whenever the orebody thickness is below 3.5 m whereas the
continuous miner approach will be used in the areas where the
orebody thickness is 3.5 m or greater. The method consists of
the extraction of a series of entries and crosscuts in the ore,
leaving pillars in place to support the back. The entries,
crosscuts and pillars have been sized using geotechnical analysis
of the local host rocks, and experience from other mines sharing
similar ground conditions.
The mine will be accessed via a covered box-cut
to establish a portal at the mine entrance from the surface,
located at the central-west part of the deposit. The mine consists
of two mining sectors: West and East. The western part, being
higher grade with a thicker mineralized zone, will be mined in
priority.
Life-of-Mine Metal
Production
The LOM production for the Copperwood Project is
shown below. Payable copper production is estimated at
300,232 tonnes (662 million pounds) with an annual
average of 29,291 tonnes (64.6 million pounds) over the
10.3-year mine life which excludes commissioning and ramp-up
period. The average payable rate is 96.5% which includes a
0.2% concentrate loss. Payable silver production over the LOM
is 1.1 million ounces with an annual average of
107 thousand ounces of silver.

Processing and Metallurgy
The process plant design for the project is
based on a metallurgical flowsheet designed to produce copper
concentrate with a nominal throughput of 6,600 tonnes per day
(“tpd”) with a planned availability of 92% for the first three
years and 6,800 tpd with an availability of 95% in the
subsequent years. The flowsheet consists of semi-autogenous
grinding in closed circuit with a ball mill targeting a primary
grind of 40 microns, rougher flotation with concentrate
regrind, cleaner flotation using three stages of cleaning,
concentrate thickening, filtration and tailings disposal.
The average copper recovery is 86% with a
weighted average copper concentrate grade of 24.7%. Studies show
that copper recovery might be further increased by concentrate
grade and reagents optimization.
Environment and Permitting
Extensive environmental studies were undertaken
to obtain the original Mining Permit issued in 2012, with
additional studies commissioned for the Mining Permit Amendment
application of 2018. In accordance with Michigan’s governing
regulation Natural Resources and Environmental Protection Act
(“NREPA”) Part 632 Nonferrous Mining, detailed studies describing
baseline conditions and potential environmental impacts were
conducted and documented in the 2018 Feasibility Study.
Since filing for amendments and renewals in
2018, all major permits required to develop the Copperwood Project
have been received. The active environmental permits are listed
here:
- Part 632 Non-Ferrous Metallic
Mining Permit
- Part 31 National Pollutant
Discharge Elimination System Permit
- Part 55 Air Permit to
Install
- Part 301 Inland Lakes and
Streams Permit
- Part 303 Wetland Permit
- Part 315 Dam Safety
Permit
- Part 325 Great Lakes Submerged
Lands Permit
The 2018 feasibility study included a water
intake station on Lake Superior to supply water for operations.
This solution required a Section 10 Permit issued by the US
Army Corps of Engineers. In 2022 and 2023, significant efforts were
put into optimizing the project. Aiming to minimize impacts to the
local site, an alternative solution to the water intake was
developed, and the Section 10 permit is no longer required. As
such, the Copperwood Project is fully permitted for construction
and operation.
Engagement with the Michigan Department of
Environment, Great Lakes and Energy (“EGLE”) will continue
throughout the detailed engineering efforts on the tailings
facility to transfer the Part 315 Dam Safety Permit from permit in
concept to a permit to construct.
Power and Surface
Infrastructure
The Company is considering a 40 km 115 kV
powerline to be built by a well-implemented energy provider, in the
Upper Peninsula. The average cost per kilowatt-hour delivered to
site will be 7.7 cents over life of mine. County Road 519 will be
upgraded to allow year-round heavy haul traffic.
Capital Costs Summary
The initial capital costs, including all direct
and indirect costs, are estimated at $425.1 million, including
a contingency of $37.6 million. Pre-production revenue of
$34.0 million (after deduction of the pre-production operating
costs) reduces the capital expenditure to $391.2 million.

Sensitivity Analysis
The Project is more sensitive to the variability
of operating costs versus the initial capital expenditures required
for the project. This builds a case for the long-term investment in
training programs, operational readiness, and continuous
improvement programs. Table 8 below shows Project sensitivity to
changes in operating and capital costs.

CAUTIONARY NOTE TO UNITED STATES
INVESTORS
Highland advises U.S. investors that this press
release contains the terms "inferred", "indicated" and "measured"
resources. All resource estimates have been prepared in accordance
with NI 43-101. NI 43-101 is a rule developed by the Canadian
Securities Administrators which establishes standards for all
public disclosure an issuer makes of scientific and technical
information concerning mineral projects. Canadian standards differ
significantly from the requirements of the United States Securities
and Exchange Commission ("SEC"), and resource information contained
therein may not be comparable to similar information disclosed by
U.S. companies. In particular, and without limiting the generality
of the foregoing, the term "resource" does not equate to the term
"reserves". "Inferred resources" have a great amount of
uncertainty as to their existence, and great uncertainty as to
their economic and legal feasibility. It cannot be assumed that all
or any part of an "inferred resource" will ever be upgraded to a
higher category. U.S. investors are cautioned not to assume that
all or part of an inferred resource exists, or is economically or
legally mineable. U.S. Investors are also cautioned not to assume
that all or any part of mineral deposits in the "measured" or
"indicated" resource categories will ever be converted into
reserves.
Neither the TSX Venture Exchange nor its
Regulation Services Provider (as that term is defined in the
policies of the TSX Venture Exchange) accepts responsibility for
the adequacy or accuracy of this release.
