NORTHCLIFF ANNOUNCES GRANT OF EXTENSION TO CONSTRUCTION START FOR SISSON PROJECT & APPOINTMENT OF NEW BOARD CHAIR

The Minister of the Department of Environment and Climate Change (DECC) has approved a five-year extension to the construction commencement timeline for Northcliff Resources Ltd.'s Sisson tungsten-molybdenum project in New Brunswick, Canada.

"On behalf of Northcliff, I would like to thank the New Brunswick government for granting the five-year extension to the construction commencement timeline. This extension provides Northcliff a runway to complete workstreams that will provide the necessary economic and technical information to support a construction decision," said Andrew Ing, Northcliff's chief executive officer.

The Sisson project received environmental impact assessment (EIA) approvals from the provincial and federal governments in 2015 and 2017, respectively, and successfully completed the Metal and Diamond Mining Effluent Regulation Schedule 2 amendment (MDMER) authorization process in July, 2019; and the Sisson Fisheries Act Authorization application and offsetting/fish habitat compensation plan process was completed and an HADD (harmful alteration, disruption or destruction) authorization under the Fisheries Act was issued by the government of Canada in October, 2020.

The Sisson project hosts a significant deposit of the critical minerals, tungsten and molybdenum. The company developed a detailed work program and is currently progressing with studies to advance the project through the preconstruction phase.

In 2025, Northcliff received funding under critical minerals initiatives in the United States and Canada. In May, the U.S. Department of Defense (DoD) awarded the company $15-million (U.S.) (approximately $20.7-million (Canadian)) under the Defense Production Act Title III program to expand tungsten's domestic capacity, sustain its critical production, and address vulnerability in the critical minerals supply chain in the United States and Canada (see May 1, 2025, release). In August, final approval was received from Natural Resources Canada (NRCan), whereby NRCan will provide contribution funding for up to $8,214,000 in support of the costs for the update of the feasibility study and basic engineering through the Global Partnerships Initiative (see Aug. 7, 2025, release). The objectives of the work being funded by NRCan are to build on and complement the programs being supported by the U.S. DoD.

Northcliff is also pleased to announce that Peter C. Mitchell has been appointed as chairman of the board of Northcliff, replacing Mr. Ing. Mr. Ing will continue as president and CEO and a director of Northcliff, focusing on project execution and financing to advance the Sisson project toward construction and production.

Mr. Mitchell is a chartered accountant (CPA/CA) with more than 35 years of senior financial management experience in both public and private companies who, in the past decade, has been extensively involved in leading and managing growth in private equity portfolio companies through acquisitions, integrations and greenfield initiatives as well as all related financing activities. Previously, he held executive leadership positions in finance and operations with companies in the United States and Canada, including Coeur Mining Inc., Taseko Mines Ltd., Vatterott Education Centers, Von Hoffmann Corp. and Crown Packaging Ltd. Mr. Mitchell holds a BA in economics from Western University and an MBA in finance from the University of British Columbia. He is a U.S. citizen based in Florida. A member of Northcliff's board of directors since 2012, he chairs the audit and risk committee and is also a member of the nominating and governance committee and the compensation committee. Mr. Mitchell is also a director of Stabilis Energy Inc., Taseko Mines Ltd. and Bear Creek Mining Corp.

"I would also like to express my appreciation to Peter for taking on the role as chairman," said Mr. Ing. "As an experienced mining executive and an active member of Northcliff's board for a number of years, he has a deep understanding of our project and the industry, which will be integral to guiding Northcliff as it advances the Sission project toward a construction decision."
