Highland Copper Signs Definitive Agreement for Sale of 34% Interest in White

Pine for US$30 Million

VANCOUVER, British Columbia, Jan. 13, 2026 -- Highland Copper Company Inc. (TSXV: HI; OTCQB: HDRSF) (" Highland

Copper" or the " Company") is pleased to announce, further to its press release of November 25, 2025, that it has signed a

definitive Membership Interest Purchase Agreement (the “Agreemen t”) with its joint venture partner, Kinterra Copper USA LLC

("Kinterra"), for the sale of the Company's 34% interest in the White Pine North Project (" White Pine ") for aggregate

consideration of approximately US$30 million (the “Transaction”).

The total consideration consists of US$18.3 million in cash, net of the outstanding principal and accrued interest on the loan

made by Kinterra to the Company's wholly owned subsidiary, Upper Peninsula Copper Holdings Inc., which is expected to

total approximately US$11.7 million at closing. In addition, the parties have agreed to suspend cash calls under the White

Pine joint operating agreement. The Company will not be obligated to make cash calls through closing, and any such cash

calls will be recorded and allocated between Kinterra and the Company only if the transaction does not close.

Proceeds from the sale of White Pine will be used to fund the Company's planned corporate and Copperwood Project

activities, eliminate existing debt, and streamline its overall corporate structure.

The parties intend to work towards closing of the Transaction in January 2026, with an outside date of February 27, 2026.

Completion of the Transaction remains subject to customary closing conditions, including approval of the TSX Venture

Exchange, as well as the discharge of various security interests held by existing streaming counterparties on White Pine and

all requisite third-party consents and releases having been obtained.

Moelis & Company LLC is acting as exclusive financial advisor and McMillan LLP is acting as legal advisor to the Company in

connection with the Transaction.

Cautionary Note Regarding Forward-Looking Information

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

statements”) within the meaning of applicable Canadian securities legislation. These statements include, without limitation,

statements with respect to the timing of completion of the Transaction and the anticipated use of the proceeds from the

Transaction. These underlying assumptions may prove to be incorrect. Important factors that could materially impact the

Company's expectations include: (i) with respect to timing for closing, that timing is subject to the receipt of necessary

approvals, and settlement of contractual arrangements with third parties, which are subject to further negotiation; (ii) with

respect to the total consideration, is based on an assumed closing date of January 31, 2026; and (iii) with respect to the use

of proceeds, is subject to: changes in Copperwood project parameters as plans continue to be refined; availability of services,

materials and skilled labour to complete work programs, testing and drilling; effects of regulation by governmental agencies;

the fact that permit extensions, renewals and amendments are subject to regulatory approvals, which may be conditioned,

delayed or denied; there is no assurance that the grant funding we have applied for will be available, and any such approval

may be subject to conditions; advancement to a construction decision at Copperwood is subject to additional studies, for

which the Company will require additional funds, which may not be available on a timely basis and accordingly could delay a

construction decision; 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; general market and industry

conditions, the results of baseline studies and test work may result in unforeseen issues which could delay or hamper

advancement of the project, and the other risks set out in the Company’s public disclosure documents, including the AIF, filed

on SEDARPlus. Although the Company believes that the assumptions and factors used in preparing the forward-looking

statements in this news release are reasonable, undue reliance should not be placed on forward looking statements. 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.
