Highland Copper Selects G Mining for Preliminary Economic Assessment on Michigan Projects

October 12, 2022 – Longueuil, Quebec. Highland Copper Company Inc. (TSXV: HI, OTCQB: HDRSF)

(“Highland Copper” or “Highland” or the “Company”) is pleased to announce that it has selected G Mining

Services Inc. (“G Mining”) to prepare a Preliminary Econ omic Assessment (“PEA”) on the combined

development scenario of its Copperwood and White Pine North projects in Michigan, USA.

Denis Miville-Deschênes, President and CEO, stated: “We are very excited about the combined scenario

PEA. It has the potential to create a larger, long-life project with considerable development and operating

synergies and a minimized environmental footprint. We look forward to working with the state of Michigan

and our key stakeholders as we define the project and its benefits.”

White Pine North and Copperwood both have significant Measured and Indicated copper resources at 3.2

billion pounds (133.4 million tonnes at 1.07% copper grade) and 1.7 billion pounds (49.3 million tonnes at

1.54% copper grade), respectively. The Inferred category is also substantial at 2.2 billion pounds for White

Pine North (97.2 million tonnes at 1.03% copper grade) and 1.3 billion pounds at Copperwood (51.5 million

tonnes at 1.16% copper grade). The Copperwood project has a Feas ibility Study dated effective June 14,

2018 that was posted to SEDAR on July 31, 2018 while the White Pine North project has a PEA dated

effective September 22, 2019 that was posted to SEDAR on November 7, 20191. Both studies contemplated

stand-alone projects and did not consider any potential synergies from combining the development and

operations activities.

The projects are located approximately 60km apart and share many similarities in deposit type, mining

method and processing. This provides Highland with significant optionality in terms of how it develops the

assets. The PEA that G Mining is undertaking on the combined scenario will consider the potential to

transport ore by rail from Copperwood to a central processing facility to be built at White Pine North. This

scenario should bring in a number of synergies as some buildings and infrastructures would be shared ,

therefore minimizing the environmental footprint and impacts if the projects are to be developed jointly.

The PEA will contemplate eliminating considerable infrastructure at Copperwood , particularly the

processing facility and tailings storage facilities as defined in the stand -alone Copperwood Feasibility

Study. In its place, the PEA will consider building a single processing facility located at White Pine. The

White Pine site is a brownfield site as the old mine operated for approximately 50 year s, until the mid-

1990s, and has significant existing infrastructure including tailing storage facilities which the project has

access to. Additionally, the White Pine North project is in close proximity to a gas distribution line , an

available power source from the grid , water supply, as well as road and rail access, although the railroad

would have to be refurbished.

The combined scenario will also assess all identified potential synergies resulting from the joint operation

of the two mines . This assessment will include the impact of a central processing facility, centralized

inventories, shared technical services and the broad impact of shared general and administrative costs. This

is expected to generate considerable savings through the operating period.

While the PEA w ill present a combined scenario , management expects that there will be staging of ore

delivery as the Copperwood project is permitted for construction and has a shorter timeline to mine

development and ore delivery . White Pine Nor th ore delivery would then be sequenced following its

permitting and development period.

In support of the PEA, metallurgical tests and other key technical work are being conducted to define the

plant design needed to process the mixed ore through a single processing line. As well, the applicability of

ore sorting technology is being studied. The Company will provide updates as results from metallurgical

and other technical tests becomes available.

1. The White Pine North PEA includes an economic analysis of mineral resources. Readers are cautioned that mineral resources that are not mineral

reserves do not have demonstrated economic viability.

Cautionary Statement

This news release contains “forward-looking statements” and “forward-looking information” (collectively

“forward-looking statements”) within the meaning of applicable Canadian securities legislation. These

include, without limitation, statements with respect to: (a) the Company’s expectations and beliefs for the

development of its mineral projects, including the timing and ultimate economic results thereof; (b) the

timing of the completion of and anticipated synergies to be recongnized in the PEA on the combined

development scenario of the Copperwood and White Pine Project (c) the Company’s plans for the

development of the projects both individually and potentially on a combined basis ; and (d) the resources

identified on the Company’s mineral projects. Such forward looking statements are based on a number of

assumptions, which may prove to be incorrect. Important assumptions with respect to each development

project are contained in Feasibility Study (for Copperwood) and the PEA ( for White Pine). Important

factors that could materially impact the Company's expectations include: uncertainties involving the

availability of financing in the debt and capital markets; uncertainties involved in the estimation of reserves

and resources, including uncertainties in the interpretation of drilling results and other geological and

geotechnical data, actual exploration results, interpretation of metallurgical characteristics of the

mineralization, changes in project parameters as plans continue to be refined; availability of skilled labour;

effects of regulation by governmental agencies; unanticipated variation in geological structures, metal

grades or recovery rates; unexpected cost increases, which could include significant increases in estimated

capital and operating costs and the effects of inflation; fluctuations in metal prices and currency exchange

rates; and general market and industry conditions. All forward-looking statements in this press release are

based on information available to the Company as of the date hereof, and the Company undertakes no

obligation to update forward-looking statements except as required by law.
