The Feasibility Study was conducted by, and under the supervision of, G Mining Services Inc. (“GMSI”) in collaboration with SGS Canada Inc. (Lakefield), Lycopodium Minerals Canada Ltd, Golder Associates and Foth Infrastructure and Environment. The study provides a comprehensive overview of the Copperwood Project and defines an economically feasible, technically and environmentally sound project.

Opportunities to Increase Copperwood Project Value

Highland and its consultants have identified a number of opportunities to increase the value of the Copperwood Project. These include upgrading inferred mineral resources, increasing mine productivity utilizing innovative continuous mining technologies, conducting further geotechnical studies to optimize ore recovery and minimize mining dilution, reviewing tailings disposal alternatives, and conducting additional testing to maximize metallurgical recoveries.

Copperwood Project

The Copperwood Project property is located, by road, approximately 22.5 km to the north of Wakefield and 40 km from the town of Ironwood, both in Gogebic County, western Upper Peninsula, Michigan. 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.

The Copperwood and its “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 sub-horizontal with a thickness that varies from 1.6 m to 3.7 m.

Mineral Resources

GMSI prepared a Mineral Resource estimate for the Copperwood Project based on data provided up to and including April 12, 2018. The resource estimate was prepared in accordance with CIM 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 Standards on Mineral Resources and Reserves. In the opinion of GMSI, the resource evaluation reported herein is a reasonable representation of the global Mineral Resources found at the Copperwood Project at the current level and spacing of sampling.

The mineral estimate was prepared under the supervision of Réjean Sirois, P. Eng. of GMSI, an independent “qualified person” as defined in NI 43‑101. Geovia GEMS™ and Leapfrog Geo™ software were used to facilitate the resource estimation process.

Total Measured and Indicated Mineral Resources of the Copperwood deposit are reported at 49.3 million tonnes grading an average of 1.54% Cu and 3.76 g/t Ag, containing 1.68 billion pounds of copper and 5.9 million ounces of silver using a cut-off grade of 1.0% Cu for the combined LCBS and UCBS. Inferred Mineral Resources are reported at 1.6 million tonnes grading an average of 1.18% Cu and 1.55 g/t Ag, containing 43 million pounds of copper and 0.1 million ounces of silver using a cut-off grade of 1.0% Cu.

Total Inferred Mineral Resources located in the satellite deposits are reported at 49.9 million tonnes grading 1.15% Cu and 3.42 g/t Ag, containing 1.27 billion pounds of copper and 5.5 million ounces of silver using a cut-off grade of 1.0% Cu for the combined LCBS and UCBS.

Mine Operations and Services

It is proposed to mine the deposit with a conventional highly mechanized, drill and blast room-and-pillar mining method. The method consists of the extraction of a series of entries and cross-cuts in the ore, leaving pillars in place to support the back. The entries, cross cuts 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 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.

The mine is split into panels, which consist of at least 12 rooms that provide multiple headings where all activities of the mining cycle can be done in parallel to achieve high productivities, as opposed to activities in series as is the case in a single heading. The mining cycle consists of drilling, explosives loading and blasting, mucking, scaling and bolting.

Mining operations are planned with two 10-hour shifts per day, 360 days per year to achieve a production target of 2.4 M tonnes per year, or 6,600 tonnes per day. To achieve this production, a total of 7 to 9 panels must be in production at any given time.

The mining operation begins with drilling of the working face, which is accomplished with two-boom hydraulic-electric jumbo drills. Each round is drilled 4.25 m (14 ft) in length with an effective break of 4.00 m. The rooms are 6.1 m wide with a height that varies according to the ore column thickness. The height dimension dictates the productivity, which varies from panel to panel.

Mucking will be done with 10 tonnes load-haul-dump (“LHD”) units that will load muck at the mine face and transport it to the conveyor loading point established for the production panel. The LHD performance will be a function of dip of the stope and distance. The conveyor loading points will be regularly moved as production advances in the panel to be less than 250 m from the headings.

Scaling of the rooms is planned with a smaller low-profile LHD unit equipped with a scaling arm that rubs the roof to remove any loose rocks.

Bolting will be done by a mechanized bolter to install roof support and wall bolts. In the stopes, 1.8 m rebar bolts are required on a 1.2 m by 1.2 m pattern with wire mesh. In addition, 1.8 m friction bolts are planned in the pillars (i.e. walls) on a 1.5 m by 1.5 m pattern with wire mesh. At room intersection rebar bolt length is increased to 2.4 m.

Ventilation for the mine will be provided by a 400 m3/s fresh air raise and two exhaust raises at the eastern and western end of the mine. The dewatering system will consist of six pumping stations capable of evacuating 2,220 l/min of underground water inflow and mine water.

Highland continues to study the use of tailings as back-fill in the open stopes. If this approach is selected, it would provide cost savings for tailing disposal and closure costs.

Life-of-Mine (LOM) Metal Production

The LOM production for the Copperwood Project is shown below. Payable copper production is estimated at 300,000 tonnes (660 million pounds) with an annual average of 28,000 tonnes (61.7 million pounds) over the 10.7-year mine life which includes a 3-month commissioning and ramp-up period. The average payable rate is 95.8% which includes a 0.2% concentrate loss. Payable silver production over the LOM is 1.10 million ounces with an annual average of 101 thousand ounces of silver.

Production Physicals   Total
Concentrate k of dmt 1,264
Cu con. Grade % Cu 24.7
Cu metal production  M lbs 690
Ag metal production k oz 2,296
Cu payable metal M lbs 660
Ag payable metal k oz 1,077

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 tpd and a planned availability of 91.3%.   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 primary observation of variability testwork showed that the copper recovery varies from 77% up to ~ 90% with a concentrate grade from 20% up to 29% Cu. The overall 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.

Studies are underway to evaluate the optimal destination and transport option for the Copperwood concentrate.

Environment and Permitting

Environmental baseline studies were done for the Copperwood Project from late 2008 through the spring of 2011. These studies were used to identify existing and historical conditions in the Project area and select potential siting of infrastructures based on an environmental management and permit approvals perspective.

An Environmental Impact Assessment was prepared to comply with the State of Michigan requirements of Part 632 of Act No. 451 of the Public Acts of 1994 as amended. This document outlines the baseline monitoring and studies conducted for the Copperwood Project including the natural, social, economic, cultural, and historical aspects of the environment that may be potentially impacted by the Project design.

In order to construct and operate the Copperwood Project, a number of permits must be obtained and agreed upon between Highland and environmental regulatory agencies on both the state and federal levels. Highland maintains an open and proactive approach with both state and federal regulators.

The major environmental permits required to develop the Copperwood Project include: 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; and Section 10 US Army Corps of Engineers Water Intake Permit.

Highland has filed amendment requests, renewals or new applications (as applicable) for these permits and expects to have all required permits by the fall of 2018.

Power and Surface Infrastructure

The Company is considering a 40 km 115 kV powerline supplied by a well-implemented energy provider in the state of Michigan. Detailed engineering will begin in the coming months for the best routing to minimize the impact on the environment. County Road 519 will be upgraded under the responsibility of the Michigan Department of Transportation.

Capital and Operating Costs

The initial capital costs, including all direct and indirect costs, are estimated at $275 million, including a contingency of $22.9 million. Pre-production revenue of $30.35 million reduces the capital expenditures to $244.6 million.

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.
