Copper Fox Congratulates TECK and Anglo American as Canadian Regulatory Approval is Received

COPPER FOX CONGRATULATES TECK AND ANGLO AMERICAN AS

CANADIAN REGULATORY APPROVAL IS RECEIVED

Calgary, Alberta, December 17, 2025. Copper Fox Metals Inc. (TSXV: CUU) (OTCQX: CPFXF)

(FSE: HPU) (“Copper Fox” or the “Company”) is pleased to share that Teck Resources Limited

(“Teck”) and Anglo American plc (“Anglo”) have received regulatory approval from the Government of

Canada under the Investment Canada Act for the “merger of equals”.

Industry Minister Mélanie Joly has approved the $53-billion Anglo Teck mega-merger, clearing the way

for the creation of one of the world’s largest copper producers following the overwhelming endorsement

of both Teck’s and Anglo’s shareholders last week. The merger previously received approval under

national security grounds in November, and lawmakers still needed to conclude that the deal would deliver

a net economic benefit to Canada under tightened takeover rules.

Elmer B. Stewart, President and CEO of Copper Fox said : “The Government of Canada’s approval is an

important step forward in the formation of Anglo Teck which will be headquartered in British Columbia,

a strong mining jurisdiction in Canada. With Anglo Teck committing to investments of at least C$4.5

billion in Canada within 5 years and within those investments i ncluding advancing the development of

the Schaft Creek copper project , a project which Copper Fox holds a 25% carried interest in with Teck,

the Company looks forward to the potential benefits for communities, Indigenous Peoples, employees and

all stakeholders.”

While the merger has secured key approvals in Canada and Australia, regulatory reviews continue

elsewhere and the full approval process could take up to 18 months. Regulators in Europe, Japan, South

Korea, the US, Chile and China are examining the deal over antitrust concerns, including whether too

much market power would be concentrated in one company. Anglo Teck would control just under 5% of

the global copper market.
