Exploration Programs

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

"forward-looking information" within the meaning of Canadian and

United States

securities law. All

statements, other than statements of historical facts, that address the advancement of the Sisson

Project towards a project finance decision, including the successful development and construction of

the planned Sisson tungsten-molybdenum mine, concentrator and APT plant to become a reliable

source of tungsten and molybdenum, and the projected average annual production of tungsten and

molybdenum are forward looking statements. Although the Company believes the expectations

expressed in such forward-looking statements are based on reasonable assumptions, such

statements are not guarantees of future performance and actual results or developments may differ

materially from those in the forward-looking statements. The assumptions used by Northcliff to

develop forward-looking statements include the following: the Company's ability to complete

construction of Sisson Project mine and facilities, the Company's ability to arrange the necessary

financing beyond to continue operations and develop the Sisson Project, the receipt of all necessary

regulatory approvals for the construction and operation of the Sisson Project; the relevant laws and

regulations in

Canada

and the US; studies and development of the Sisson Project will continue to be

positive; our expectations of continued availability of capital and debt financing, and no geological or

technical problems will occur. Forward-looking information is subject to a variety of risks and

changes, uncertainties with respect to the receipt or timing of required permits, approvals and

agreements for the development of the Sisson Project, the Company may not be able to secure

offtake agreements for the metals to be produced at the Sisson Project, the inherent risks involved

in the exploration and development of mineral properties and in the mining industry in general, the

financial markets and in the demand and market price for tungsten, molybdenum and other minerals

and commodities, and fluctuations in exchange rates, particularly with respect to the value of the US

Dollar and Canadian Dollar; the exploration and development of properties located within First

Nations treaty and Aboriginal groups asserted territories may affect or be perceived to affect treaty

and asserted aboriginal rights and title, which may cause permitting delays or opposition by

Aboriginal groups or communities, environmental issues and liabilities associated with mining

including processing and stockpiling; changes in government policies regarding mining and natural

resource exploration and exploitation, continued availability of capital and financing, and general

economic, market or business conditions, as well as risks relating to the uncertainties with respect to
