ADEX MINING ENGAGES MONETA SECURITIES TO LEAD 100% SALE OF MOUNT
PLEASANT MINE IN NEW BRUNSWICK
Toronto, ON – June 26, 2025 – Adex Mining Inc. (“Adex” or the “Company”) (TSX‐V: ADE) is
pleased to provide an update on the strategic review being conducted by the special committee of the
board of directors of the Company (the "Special Committee"), together with its external advisor Moneta
Securities (Alberta) Corp. ("Moneta") that was previously announced by the Company on May 15, 2025.
Based on work conducted to date by the Special Committee in consultation with Moneta, an asset sale of
the Company's wholly owned Mount Pleasant Mine Property, has emerged as the preferred alternative for
the Special Committee and the board of directors of the Company. In accordance with Moneta's
previously announced strategic review engagement, Moneta has now been mandated to pursue bids for
the strategic asset sale.
The Company's Special Committee has determined that a full asset sale is in the best interests of
stakeholders, given strong inbound interest and growing demand for secure, domestic sources of critical
minerals. Moneta will oversee a structured sale process targeting both domestic and international strategic
and financial acquirers. Non-binding bids in connection with the asset sale are due by the end of July
2025. Any parties interested in the Mount Pleasant Mine Property should contact Moneta directly.
THE M
OUNT PLEASANT MINE PROPERTY
The Mount Pleasant Mine Property is a past-producing operation with fully built infrastructure, a
permitted tailings facility, and underground access. Located in Charlotte County, New Brunswick, the
Mount Pleasant Mine Property is 80 kilometers south of Fredericton, the provincial capital, and 65
kilometers from the United States border. Strategically located near the United States border with road
and grid power connectivity, the Mount Pleasant Mine Property represents a rare opportunity to acquire
an advanced-stage Canadian critical minerals asset.
The Mount Pleasant Mine Property is Canada’s only known deposit containing significant quantities of
tungsten, molybdenum, tin, bismuth, and indium. It has benefited from extensive historical exploration
and feasibility-level work, with a strong foundation for near-term development.
The project includes:
• Past-producing mine (~990,200 tonnes processed) with existing shaft access, surface
infrastructure, and a permitted tailings facility;
• One of North America’s largest undeveloped tungsten-polymetallic resources;
• Historical measured and indicated (M&I) resource estimate (the Mount Pleasant Technical Report

• Extensive historical capital investment and technical studies;
• Exposure to strategic critical minerals aligned with North American supply chain priorities; and
• Full permittance for advanced exploration with dewatering and underground infrastructure in
p
lace.
Scientific and technical information in this news release relating to the Mount Pleasant Mine Property is
historical in nature and is derived from the technical report titled “Amended Technical Report of the
Mount Pleasant Property, including Mineral Resource Estimates, Southwestern New Brunswick for Adex
Mining Inc.” dated April 13, 2012, and amended on October 11, 2013, prepared for the Company by
Steven McCutcheon, Ph.D., P.Geo., of McCutcheon Geo-Consulting, John Reddick, M.Sc., P.Geo., of
Reddick Consulting Inc., and Watts, Griffis and McOuat Limited, Tim McKeen, P.Eng., and Stephanie
Scott, P.Eng., of Thibault & Associates Inc., Dorota El-Rassi, P.Eng., of SRK Consulting and Michael
Kociumbas, P.Geo., of Watts Griffis and McOuat Limited. (the “Mount Pleasant Technical Report”).
Reference should be made to the full text of the Mount Pleasant Technical Report, which was prepared in
accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-
101”) and is available electronically on SEDAR+ under Adex's issuer profile.
The foregoing historical scientific and technical information and statements regarding historical mineral
estimates in relation to the Mount Pleasant Mine Property are no longer current and should not be relied
upon. The Company has not prepared any more recent estimates since the historical estimates referred to
above. While the Company generally believes these estimates to be reliable historical estimates of
mineralized material contained in the Mount Pleasant Mine Property, their relevance is qualified by the
amount of time that has passed since the effective date of those estimates. A qualified person under NI 43-
101 has not done sufficient work to classify the historical estimates presented above as current mineral
resources or mineral reserves and Adex is not treating the historical estimates as current mineral resources
or reserves. Additional drilling and sampling and quality control, amongst other things, will be required to
verify the historical estimate as current mineral resources or mineral reserves.
The historical estimates were prepared based on the Canadian Institute of Mining Metallurgy and
Petroleum (“CIM”) Definition Standards on Mineral Resources and Reserves (“CIM Definition
Standards”) adopted by CIM Council on November 27, 2010 (the “2010 CIM Definition Standards”). The
2010 CIM Definition Standards were updated by CIM in 2014 to create the current standards ("2014 CIM
Definition Standards") that harmonize Canadian definitions with other members of the Committee for
Mineral Reserve International Reporting Standards (CRIRSCO). In particular, the 2010 CIM Definition
Standards omitted the "reasonable prospectus for eventual economic extraction" component, which the
2014 CIM Definition Standards incorporated to align with other CRIRSCO members. The 2014 CIM
Definition Standards also updated mineral reserves categorization require the reference point at which
mineral reserves are defined to be stated.
The scientific and technical information contained in this news release has been reviewed and
approved by Robin Adair, a “Qualified Person” (“QP”) as defined in NI 43-101. Robin Adair is
independent of the Company and is a Professional Geologist registered in New Brunswick.
