Highland Copper Company Inc. (TSX-V: HI) (OTCQB: HDRSF) is pleased to announce, further to its press releases dated November 25, 2025 and January 13, 2026, that it has completed the sale of the Company’s 34% interest in the White Pine North Project to its joint venture partner, Kinterra Copper USA LLC, for aggregate consideration of US$30.1 million, pursuant to a definitive Membership Interest Purchase Agreement dated January 12, 2026.

The total consideration consisted 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 was a total of US$11.8 million at closing.

Proceeds from the sale of White Pine will be used to fund planned Copperwood Project activities, eliminate the existing debt to Kinterra, pay for the costs of the Transaction, and for general working capital.

“In divesting our non-controlling stake in White Pine, we are pleased to demonstrate a clear focus on our 100% owned, fully permitted Copperwood Project,” said Barry O’Shea, CEO of Highland Copper. “The divestment serves to eliminate debt and capitalize Copperwood to a construction decision. With the proceeds, we look forward to progressing detailed engineering, construction readiness and project financing through 2026.”

Concurrently with the Transaction the Company entered into an amendment to the Silver Royalty Option with OR Royalties Inc. on the Copperwood Project that is generally consistent with the Silver Royalty Option already in place. Pursuant to the Silver Royalty Option, OR Royalties has the option to increase its NSR royalty on silver produced from the Copperwood Project from 11.5% to 100% by paying the Company US$3.0 million on December 31, 2027, subject to certain conditions and the right of OR Royalties to extend the time for the payment by one year.

Moelis & Company LLC acted as exclusive financial advisor to the Company in connection with the Transaction and received a fee compliant with the TSXV policies. McMillan LLP acted as legal advisor to the Company.
