UTH32 LIMITED (“SOUTH32”) AND TRILOGY METALS INC RECORD OF DECISION FILED FOR THE AMBLER ACCESS ROAD
South32 Limited (“South32”) and Trilogy Metals Inc. (TSX, NYSE American: TMQ) (“Trilogy Metals”), partners in Ambler Metals LLC
(“Ambler Metals”), are pleased to report the signing of the Record of Decision (“RoD”) by the United States Bureau of Land
Management (“BLM”) for the Ambler Mining District Industrial Access Project (“AMDIAP ” or “Ambler Access Road”). The RoD
approves the development of the northern or “A” route which is to be a 211-mile-long gravel private access road in the southern
Brooks Range foothills to provide industrial access to the Ambler Mining District. All amounts are in United States dollars unless
otherwise stated.
The Section 404 Permit, which is governed by the Clean Water Act (“CWA”), will be issued shortly by the United States Army Corp.
of Engineers (“USACE”).
The permitting of the proposed Ambler Access Road is a significant milestone in the development of the Ambler Mining District.
The development of the road will unlock the world class economic potential of the region by allowing greater access to the district
and the potential development of the Arctic project, which is in a remote area of northwest Alaska.
South32 CEO Graham Kerr said, “We welcome the Record of Decision, a key milestone to further progress the Ambler Metals
project. We look forward to conti nuing our partnership with Trilogy to unlock the value of the project’s high- quality base and
precious metals resources, working together to advance it through the current study phase.”
President and CEO, Tony Giardini, of Trilogy Metals said , “I would like to express my sincere appreciation to the BLM and the
USACE for overseeing and managing the long approval process for the Ambler Access Road. The formal permitting of the AMDIAP
is a significant event for the Company and for all Alaskans.”
Next Steps
On June 24, 2020, the Board of Directors of the Alaska Industrial Development and Export Authority (“ AIDEA”), approved a
Memorandum of Understanding (“MOU”) with Ambler Metals which specifies how the parties will jointly establish a plan
regarding the permitting, feasibility, engineering and design, construction and operation, financing and closure of the AMDIAP.
Ambler Metals has committed to contribute up to $35 million to match AIDEA’s contribution of $35 million for these activities.
AIDEA aut horized spending up to $500,000 from the funds currently in the Arctic Infrastructure Development Fund for 2020
predevelopment work on the AMDIAP. These funds will be matched by another $500,000 by Ambler Metals and will be used to
further advance the project.
The issuance of the CWA Section 404 will establish a program to regulate the discharge of dredged or fill material into waters of
the United States, including wetlands. This is the key federal permit required for the development of the AMDIAP.
