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

On November 14, 2025, Northcliff Resources announced two key developments for its Sisson Tungsten-Molybdenum Project in New Brunswick. First, the provincial government granted a five-year extension to the construction commencement timeline. Second, the company appointed Peter C. Mitchell as the new Chairman of the Board. Mr. Mitchell is an experienced mining executive and has been an active member of Northcliff's board.

This news is materially positive as it significantly de-risks the Sisson Project's development timeline. The five-year extension to the construction commencement requirement was a critical upcoming hurdle. Securing this extension provides the company with a clear and sufficient runway to complete the ongoing Feasibility Study (FS) update and other pre-construction workstreams without the pressure of a looming deadline that could have jeopardized the project's permits.

This announcement follows the extremely impactful news from the previous day (November 13), where the Sisson Project was included on Canada's "Nation Building Projects List." While that news was the primary catalyst for the stock's massive re-rating, today's news is a necessary and logical follow-up. It provides tangible proof that the project has the full support of its provincial regulators, complementing the federal support.

The appointment of an existing board member, Peter C. Mitchell, to Chairman is a sign of stability and continuity in leadership as the project advances.

In the context of the historical news, this is the culmination of a series of positive de-risking events that began in May 2025 with the announcement of US and Canadian government funding. The company has successfully transitioned from a cash-strapped entity to one with government backing and now, a secure long-term development timeline. This extension was essential for the government funding to be effectively deployed towards the FS update and engineering work.

Northcliff Resources Ltd. is a Canadian-based development-stage company. Its sole focus is the Sisson Tungsten-Molybdenum Project in New Brunswick, Canada. The Sisson Project is one of the largest undeveloped tungsten deposits in the world outside of China. It is considered a critical minerals project and has received key federal and provincial environmental permits. The project has been significantly de-risked through substantial government funding from both Canada and the United States, aimed at updating its 2013 Feasibility Study and advancing it toward a construction decision.
