Amarc Confirms Boliden’S Ongoing Participation at Duke Copper-GOLD District and Provides District Update
AMARC CONFIRMS BOLIDEN’S ONGOING PARTICIPATION AT DUKE COPPER-GOLD DISTRICT
AND PROVIDES DISTRICT UPDATE
April 2, 2026 - Amarc Resources Ltd. (“Amarc” or the “Company”) (TSXV: AHR; OTCQB: AXREF) is pleased to announce
the continued participation of Boliden Mineral Canada Ltd. (“Boliden”) in the exploration of the DUKE District (or the
“District”). Effective as of April 1, 2026, a Boliden 60% /Amarc 40% Joint Venture (the “DUKE JV”) as defined by the
Mineral Property Earn -in Agreement, dated November 21, 2022, has commenced . Boliden has, to the end of 2025 ,
completed an investment of $30 million to earn its 60% interest and has elected not to exercise the option to increase
its interest from 60% to 70% by investing a further $60 million. Under the JV, Boliden can now invest 60% and Amarc
40% in future programs or dilute their interest in the DUKE JV. A 2026 exploration program is currently being planned
to explore and drill several copper-gold ("Cu-Au") deposit targets across the 732 km 2 District. Amarc will continue as
project operator. The goal of the DUKE JV is to be a substantial party to the potential establishment of an important
British Columbia (“BC”) porphyry Cu-Au district.
The DUKE District is located 80 km northeast of Smithers within the Babine Region, a well mineralized porphyry belt in
BC, hosting the former Bell and Granisle Cu-Au mines that were operated by Noranda Mines, and the advanced stage
Cu-Au Morrison deposit owned by a third party. Significant potential exists for discovery of new porphyry Cu -Au
deposits. Notable infrastructure is in place to service the former mines and the forestry and mineral exploration
industries, including an extensive network of forest roads across the DUKE District.
Amarc's DUKE District programs have substantially expanded the DUKE Deposit and revealed strong potential for the
development of a porphyry Cu-Au district (see Amarc release July 2, 2025). This systematic and extensive exploration
continues to identify prospective, Cu-Au mineralized targets while efficiently screening out less prospective areas. In
2025, greenfield reconnaissance scale Induced Polarization ground geophysical survey work (58 line-km), geochemical
(1,012 soil samples) and geological surveys, were combined with the drilling of 36 holes (9,208 m) comprising five holes
at the DUKE Deposit and DUKE Offset and 31 scout holes other target areas throughout the extensive tenure.
Notably, the large DUKE Cu-Mo-Au-Ag Deposit lies approximately 6 km to the southeast of American Eagle’s promising
NAK Cu -Au Deposit (see American Eagle website https://americaneaglegold.ca). Figure 1 illustrates a structural
periodicity along the southeast trending regional NAK–DUKE magnetic corridor. The NAK and DUKE Deposits, outlined
in red, are situated within evenly-spaced, recurring clusters of magnetic anomalies. The DUKE JV’s targets C6 and M4
display a continuation of this recurring pattern to the southeast of the DUKE Deposit, showing magnetic anomalies
clustering at repeated 6 km spacings. These exploration targets are interpreted to reflect zones of fault intersections
with regional southeast trending structures, representing mineralizing fluid pathways analogous to those responsible
for most deposits in the Babine Region . Future exploration by the DUKE JV will focus on identifying prospective
chargeability and geochemical anomalies across these target regions to firm-up drill targets.

Drilling at the DUKE Deposit has identified a porphyry system extending to over 650 m north-south by 800 m east-west
and to a depth of over 600 m, while underscoring the potential for further significant expansion (Figure 2, and see
Amarc releases December 13, 2023 and June 25, 2024).

Highlights from previous drilling at the DUKE Deposit include (see Amarc release June 25, 2024):
• 71 m of 0.45% CuEQ1 (0.35% Cu, 0.016% Mo, 0.06 g/t Au, 1.6 g/t Ag) and 104 m of 0.38% CuEQ (0.29% Cu,
0.016% Mo, 0.06 g/t Au, 1.3 g/t Ag) in hole DK24033
• 110 m of 0.38% CuEQ (0.25% Cu, 0.028% Mo, 0.04 g/t Au, 1.1 g/t Ag) and
30 m of 0.39% CuEQ (0.26% Cu, 0.025% Mo, 0.05 g/t Au, 1.4 g/t Ag) in hole DK24034
• 15 m of 0.69% CuEQ (0.52% Cu, 0.024% Mo, 0.11 g/t Au, 2.9 g/t Ag) and
29 m of 0.47% CuEQ (0.31% Cu, 0.030% Mo, 0.06 g/t Au, 1.7 g/t Ag) within
209 m of 0.26% CuEQ (0.19% Cu, 0.013% Mo, 0.04 g/t Au and 1.0 g/t Ag) in hole DK24037
• 183 m of 0.43% CuEQ (0.31% Cu, 0.019% Mo, 0.07 g/t Au,1.5 g/t Ag) in hole DK22009
• 217 m of 0.45% CuEQ (0.33% Cu, 0.018% Mo, 0.08 g/t Au, 1.5 g/t Ag) in hole DK22010
• 83 m of 0.41% CuEQ (0.30% Cu, 0.017% Mo, 0.06 g/t Au, 1.1 g/t Ag) in hole DK23022
Note 1. Copper equivalent (CuEQ) calculations use metal prices of: Cu US$4/lb, Mo US$15/lb, Au US$1,800/oz and Ag US$24/oz and
conceptual recoveries of: Cu 85%, Mo 82%, Au 72% and 67% Ag.
During 2025, five drill holes were completed in the greater DUKE Target area (Figure 2 and Table 1). These include two
holes (DK25086, DK25087) drilled within the east-west trending South Graben Fault (“SGF”) structural corridor which,
like many other mineralized corridors in the Babine Region, is proving to have a spatial relationship to the development
of significant Cu-Mo mineralized zones (see Amarc release June 25, 2 024). A few short historical holes drilled in the
1970’s cut the shallowest portions of this targeted volume to the south of the DUKE Deposit. In most cases the holes
were well mineralized, for example, 70-02 returned 113 m of 0.38% CuEQ (0.29% Cu, 0.012% Mo, 0.06 g/t Au, 1.1 g/t
Ag), including 12 m of 0.51% CuEQ (0.41% Cu, 0.010% Mo, 0.09 g/t Au, 1.6 g/t Ag) (see Amarc DUKE Project 2020
Technical Report available on the website at https://amarcresources.com/projects/duke-project/technical-report).
Hole DK25086 returned 211 m of 0.25% CuEQ (0.19% Cu, 0.01% Mo, 0.03 g/t Au, 1.0 g/t Ag) from 151 m, including 89
m of 0.33% CuEQ (0.24% Cu, 0.02% Mo, 0.04 g/t Au, 1.2 g/t Ag) from 273 m, and hole DK25087 returned 66 m of 0.10%
CuEQ (0.08% Cu, 0.01 g/t Au , 0.4 g/t Ag) from 13 7 m. These newly identified mineralized volumes are open to
expansion with further drilling.

Additionally in 2025, three holes were drilled along a 440 m long east -west fence across the southern end of DUKE
Offset (120 m to 150 m south of previous drilling, Figure 2 and Table 1), extending this deposit-area. Previous drilling
by Amarc within the DUKE Offset encountered important Cu-Mo mineralization outlining a newly recognized volume
of mineralized rock west of the DUKE Fault. This represents a portion of the DUKE Deposit of unknown extent that was
displaced some 450 to 500 m northwards (see Amarc release June 25, 2024). Hole DK25085 returned 84 m at 0.16%
CuEQ (0.10% Cu, 0.01% Mo, 0.02 g/t Au, 1.0 g/t Ag) from 105 m, hole DK25094 returned 12 m of 0.16% CuEQ (0.09%
Cu, 0.02% Mo, 0.01 g/t Au, 0.5 g/t Ag) from 54 m, and hole DK25093 returned 31 m of 0.18% CuEQ (0.13% Cu, 0.01%
Mo, 0.02 g/t Au, 0.6 g/t Ag) from 31 m, 95 m of 0.13% CuEQ (0.10% Cu, 0.02 g/t Au, 0.5 g/t Ag) from 101 m, 74 m of
0.18% CuEQ (0.11 Cu, 0.01% Mo, 0.09 g/t Au, 0.9 g/t Ag) from 219 m and 36 m of 0.20% CuEQ (0.15% Cu, 0.05 g/t Au,
1.4 g/t Ag) from 314 m. The DUKE Offset area now extends over greater than 400 m north-south, 450 m east-west and
250 m in depth.
Also in 2025, drilling in the DUKE District included five holes completed across a 2.3 km long east-northeast trending
fence on the north side of the N AK Deposit mineral tenure that confirmed a centre of anomalous porphyry-style Cu-
Au mineralization (Table 1). Drill hole DKC25074 returned 86 m of 0.13% CuEQ (0.10% Cu, 0.03 g/t Au, 2.3 g/t Ag) from
46 m, including 38 m at 0.22% CuEQ (0.19% Cu, 0.03 g/t Au, 2.1 g/t Ag) from 59 m (Table 1). Elsewhere along this drill
fence, hole DKC25071 encountered both 10 and 67 m intervals of anomalous Cu ranging from 0.08% to 0.06% Cu and
0.09 to 0.06 g/t Au.
Other mainly short scout holes at other targets did not return significant results.

About Amarc Resources Ltd.
Amarc is a mineral exploration and development company with an experienced and successful management team
focused on developing a new generation of long -life, high -value porphyry Cu -Au mines in BC. By combining high -
demand projects with dynamic management, Amarc has created a solid platform to create value from its exploration
and development -stage assets.
Amarc is advancing the JOY, DUKE and IKE porphyry Cu±Au Districts located in different prolific porphyry regions of
northern, central and southern BC, respectively. Each District represents significant potential for the development
of multiple and importan t-scale, porphyry Cu±Au deposits. Importantly, each of the three districts are located in
proximity to industrial infrastructure – including power, highways and rail.
At JOY, Freeport-McMoRan Mineral Properties Canada Inc. ("Freeport"), a wholly owned subsidiary of Freeport -
McMoRan Inc. earned, under the Mineral Property Earn -In Agreement, an initial 60% interest in the JOY District by
funding CAD $35 million under an accelerated timeframe (see Amarc releases May 12, 2021 and May 29, 2025). The
District is now being advanced through AuRORA Minerals Ltd, (“AML”) a private joint venture corporation held 60% by
Freeport and 40% by Amarc (see September 4, 2025 release). Freeport has elected to earn a further 10% interest in
the JOY District by f unding an additional $75 million in staged expenditures. While Freeport is now the Operator of
JOY, Aurora Minerals Ltd., the joint venture company has appointed Amarc as the primary contractor to continue to
manage the JOY exploration programs under a sep arate Services Agreement. In support of this momentum, Amarc
executed on behalf of AML, an expanded exploration program exceeding CAD $16+ million in 2025, completing
substantial drilling at AuRORA and across multiple other deposit targets.
At the DUKE District , Boliden Mineral Canada Ltd. (“Boliden”) , an entity within the Boliden Group of companies,
continues its participation having sole funded CAD$30 M of exploration expenditures though to the end of 2025.
Boliden and Amarc have now entered a 60:40 joint venture (the “DUKE JV”) under which the parties m ust fund
exploration activities on a pro rata basis or dilute their interest in the DUKE JV. Amarc is the operator at the DUKE
District.
Amarc owns a 100% interest in the IKE Cu -Au District in southern BC. Amarc completed self -funded drilling at its
Empress Cu-Au Deposit in the IKE District in 2024. Amarc is the operator at the IKE District.
Amarc's exploration is led by an internationally successful team of experienced geologists specializing in porphyry
Cu-Au deposits. Members of this team have been involved in and have tracked porphyry Cu -Au exploration
advancements in the Toodoggone region since 1990. Their experience and early recognition of the porphyry
potential at the NWG Target in terms of a shallowly overburden covered and underexplored transitional epithermal -
porphyry geological setting, led to the discovery of the Au -rich AuRORA por phyry Cu-Au-Ag Deposit.
Amarc is associated with HDI, a diversified, global mining company with a 35 -year history of porphyry Cu deposit
discovery, development and transaction success. Previous and current HDI projects include some of BC's and the
world's most important porphyry deposits – such as Pebble, Mount Milligan, Southern Star, Kemess South, Kemess
North, Gibraltar, Prosperity, Xietongmen, Newtongmen, Florence, Casino, Sisson, Maggie, PINE, IK E, DUKE and
AuRORA. From its head office in Vancouver, Canada, HDI applies its un ique strengths and capabilities to acquire,
develop, operate and monetize mineral projects.
Amarc works closely with local governments, Indigenous groups and stakeholders in order to advance its mineral
projects responsibly, and in a manner that contributes to sustainable community and economic development. We
pursue early and meaningful engageme nt to ensure our mineral exploration and development activities are well
coordinated and broadly supported, address local priorities and concerns, and optimize opportunities for
collaboration. In particular, we seek to establish mutually beneficial partner ships with Indigenous groups within
whose traditional territories our projects are located, through the provision of jobs, training programs, contract
opportunities, capacit y funding agreements and sponsorship of community events. All Amarc work programs are
carefully planned to achieve high levels of environmental and social performance.

Quality Assurance/Quality Control Program
Amarc drilled 36 NQ (47.6mm) size diamond drill core holes in 2025 in the DUKE District. All drill core was logged,
photographed, and cut in half with a diamond saw. Half core samples from the DUKE drilling were sent to ALS
Laboratories, Kamloops or Langley, BC, Canada, f or preparation and to North Vancouver, BC, Canada for analysis. All
facilities are ISO/IEC 17025:2017 accredited. At the laboratory, all drill core and surface rock samples were dried,
crushed to 70% passing to <2mm, and a 250 g split was p ulverized to better than 85% passing 75 microns. Samples
were analyzed for Au by fire assay fusion from a 30 g sub-sample with an ICP-AES finish, and for 60 elements including
Cu, Mo and Ag by a four -acid digestion, multi -element ICP -MS package. As part of a comprehensive Quality
Assurance/Quality Control ("QAQC") program, Amarc control samples were inserted in each analytical batch of the
drill core samples at the following rates: standards one in 20 regular samples, in -line replicates one in 20 regular
samples and one coarse blank per hole. The control sample results were then checked to ensure for appropriate QAQC
protocol and best practice.
