NORTHCLIFF ANNOUNCES PROGRESS REPORT ON PROGRAM TO ADVANCE DEVELOPMENT OF THE SISSON CRITICAL MINERALS PROJECT

VANCOUVER, BC, June 26, 2025 /CNW/ - Northcliff Resources Ltd. ("Northcliff" or the "Company") (TSX: NCF) is pleased to announce that it has engaged Ausenco Engineering Canada ULC ("Ausenco") to lead the update of the feasibility study ("FS Update") for its Sisson Tungsten-Molybdenum Project (the "Sisson Project"), a critical minerals project located in New Brunswick, Canada.

A key part of Northcliff's comprehensive program (see Northcliff's May 1, 2025 news release), the FS update is designed to provide the necessary economic and technical information to support a construction decision on the Sisson Project. Work on the FS Update is fully underway and other aspects of the planned pre-construction work program have been initiated. These include multiple engineering workstreams and studies required to meet the technical conditions associated with Northcliff's in-hand environmental approvals, as well as detailed project development planning, project finance and offtake engagement. 

Located near tidewater on the southeastern coast of Canada in New Brunswick, the Sisson Project hosts a deposit with the Critical Mineral tungsten and the strategic mineral molybdenum. If developed, the Sisson Project has the prospects of becoming an accessible and reliable supplier of tungsten and molybdenum, strengthening and diversifying the supply chain for these metals used in important industrial, electronic, aerospace and defense applications, and new technologies.

Northcliff advanced resource, engineering, environmental and economic studies that culminated in a positive feasibility study in 2013, then progressed the project through provincial and federal environmental assessment and other processes to gain key approvals, expending some C$70 million. In the 2013 feasibility study, development of the Sisson Project was proposed as an open pit mine with conventional processing facilities, supplemented by value-added downstream and on-site processing of tungsten concentrates in an ammonium paratungstate ("APT") plant. 

Andrew Ing, Northcliff's Chairman, President and CEO commented, "We are excited to be moving forward with our comprehensive program for Sisson, advancing our goal to become a reliable and easily accessible producer of tungsten and molybdenum. I would like to acknowledge Ausenco as the leader of the feasibility study update and to recognize the readiness of its team as the work on it is well underway."

The disclosure of scientific and technical information contained in this news release has been reviewed and approved by Tanya Yang, P.Eng., a Qualified Person who is not independent of the Company.
