Amarc Launches $10 Million 2025 Duke Copper-GOLD District Drilling: Provides District Update
AMARC LAUNCHES $10 MILLION 2025 DUKE COPPER-GOLD DISTRICT DRILLING:
PROVIDES DISTRICT UPDATE
July 2, 2025 - Amarc Resources Ltd. ("Amarc" or the "Company") (TSXV: AHR; OTCQB: AXREF) is pleased to
announce that it has commenced an extensive 2025 drill program at its 100% owned DUKE Copper-Gold district
(“DUKE District” or “District”) in central BriVsh Columbia (“BC”). Drilling is planned to test a number of copper-
gold (“Cu-Au”) deposit targets across the 732 km2 District. This year’s program - budgeted at $10 million - will
again be funded by Boliden (see release December 17, 2024), which is earning-in at DUKE. Amarc is the project
operator.
“We are excited to be back out on the ground in collabora_on with Boliden to con_nue to advance the DUKE
District,” said Diane Nicolson, President and CEO. “Amarc’s systema_c approach to explora_on is discovering
new occurrences of copper-gold mineraliza_on in a region with half a century of explora_on history. Drilling and
survey work will step out to the north and south from the centrally located, open-ended DUKE porphyry Cu-Mo-
Ag Deposit to test mul_ple copper-gold targets to unlock the further poten_al throughout the District. In
addi_on to the successful scout drilling at the targets described below, some nine targets remain to be tested
for the first _me in 2025.”
“As Canada looks towards capitalizing on its cri_cal mineral endowment, both the need and the opportunity,
are clear. According to recent research1, copper prices need to double to provide the necessary impetus for
companies to develop the mines at the rate necessary to ‘sa_ate the rapid consump_on of metal driven by
…economic development and clean energy’ across the globe,” added Nicolson. “Amarc’s con_nued focus on the
discovery and development of new copper-gold deposits at DUKE and at our other BC Cu-Au Districts such as
AuRORA, Empress and IKE have the real poten_al to contribute to the provincial economy and, in par_cular,
that of the local communi_es.”
Amarc’s DUKE District is located 80 km northeast of Smithers within the Babine Region, one of the most
mineralized porphyry belts in BC. It hosts the former Bell and Granisle Cu-Au mines that were operated by Noranda
Mines, and Morrison, an advanced stage Cu-Au deposit owned by a third party. Significant potenVal exists for
discovery of new large porphyry Cu-Au deposits. Infrastructure servicing the former mines and the forestry and
mineral exploraVon industries is nearby. There is an extensive network of forest roads and much of the D UKE
District is road accessible.

DUKE District Update – Significance of Ini_al Scout “Greenfields Drilling” at the JO, C4 and Svea Cu-Au Targets
Over a Vmespan of less than 12 months, Amarc’s DUKE District program has revealed hallmarks of early-stage
exploraVon success within a greenfields district.
• The systemaVc and extensive exploraVon model used by Amarc in 2023 and 2024 is permidng the cost-
effecVve idenVficaVon of prospecVve mineralized targets while screening out less prospecVve areas.
• In addiVon to the JO, C4 and Svea Targets discussed below, Amarc has built a pipeline of early-stage
reconnaissance scale targets to be drill tested.
• The effecVve use of reconnaissance scale Induced PolarizaVon (“IP”) and airborne magneVc geophysical
surveys, along with geochemical and geological surveys for target delineaVon, followed by iniVal scout
drilling, is idenVfying the presence of mineralized bioVte -feldspar porphyry (“BFP”) intrusions. BFP
intrusions are associated with most of the major porphyry Cu-Au-Mo deposits (Granisle, Bell, Morrison,
DUKE and Nak) in the Babine Region. BFP intrusions hosVng porphyry style Cu-Au mineralizaVon have been
recognized at the JO and C4 Targets for the first Vme.
• Cu-Au raVos at the C4 and Svea occurrences indicate that the BFP intrusions are Au-enriched.
• The presence of Au enhanced intervals at the JO Target is considered significant: gold-zinc mineralizaVon
is hosted within sulphide-rich black clasVc sediments and may represent an ancillary deposit target type
in the DUKE District.
• The iniVal drill programs at the JO, C4 and Svea targets idenVfied prospecVve mineralized environments.
Defining the scale of higher-grade mineralizaVon within these permissive environments will be the focus
of the 2025 drill programs at these and similar targets.
In 2024, Amarc completed 19 scout core holes (5,815 m) at three porphyry Cu-Au deposit targets - JO, C4 and
Svea. All three targets are located to the north of the DUKE Deposit (see Figure 1 and release June 25, 2024). The
JO and C4 Targets were not previously known and had not been drill tested. The Svea Target had limited shallow
historical drill tesVng in the late 1960’s and early 1970’s.

New Porphyry Cu-Au Targets for Drill TesVng
JO Deposit Target - Porphyry Cu-Au and Volcanic-Sediment Associated Au
The effectiveness of the on-going surveys completed across the DUKE District is highlighted by the JO Target, which
is a new discovery of Cu-Au mineralization. The approximately 3 km2 target, as defined by IP chargeability and co-
incident aeromagnetic anomalies, is largely overburden covered. Sporadic anomalous concentrations of Cu (51-
192 ppm) and Au (15-71 ppb) were returned from soil geochemistry over a comprehensive survey grid. A
composite rock chip sample taken from the discovery outcrop over approximately 3 m2 from a roadside gravel pit
returned 0.18% Cu, 0.52 g/t Au, 16 g/t Ag and 55 ppm Mo in a strongly pyritic BFP. Six broadly spaced scout core
drill holes (2,266 m) were completed in 2024 on the east lobe of the JO target (see Figure 1, Tables 1 and 2).
Drilling Highlights
• The geophysical anomalies in the JO target area are underlain by a large (potenVally greater than 1.5 km2)
BFP intrusion.
• Parts of this BFP intrusion are significantly mineralized, for example, DKJ24043 returned 71 m of 0.13%
CuEQ (see Table 1) from 71 m, and could indicate proximity to a porphyry deposit. The area remains to be
fully drill tested.
• Drill hole DKJ24042 returned an interesVng 3 m of 3.56 g/t Au from 305 m including zinc concentraVon of
3,960 ppm, hosted within a fine grained, sulphide rich black clasVc sediment. Discrete quartz veins are not
present in this interval and enhanced gold-zinc mineralizaVon in fine grained, carbon rich sediments may
represent a previously unrecognized style of mineralizaVon in this camp.
• Notably the west lobe of the strong IP chargeability anomaly, is located approximately 1 km due west of
the area of JO drilling and remains to be drill tested.
C4 Deposit Target - Porphyry Cu-Au
Like JO, the C4 Target area is characterised by extensive overburden cover. The target is defined by a 4 km2 IP
chargeability high with an internal aeromagneVc high anomaly, and anomalous Cu-Au concentraVons in sporadic
soil geochemical samples. Three inaugural scout holes (777 m) drilled at the C4 Target in 2024 successfully
intercepted previously unknown BFP hosted porphyry Cu-Au mineralizaVon (see Figure 1, Tables 1 and 2).
Drilling Highlights
• C4 exhibits early-stage exploraVon signatures of a potenVal Au enriched porphyry Cu with drillhole
DKC24058 coring 48 m (from 73 m) of 0.11 g/t Au within a slightly broader 53 m (from 68 m) interval coring
0.16% CuEQ.
• MineralizaVon may also be associated with intermediate (BFP) and mafic dykes that form proximal to
intrusions; an example is drill hole DKC24058 that intercepted 14 m (from 163 m) of 0.19% CuEQ. This style
of mineralizaVon has been described at the Nak occurrence (see hnps://americaneaglegold.ca).
• MineralizaVon has been intercepted by the three holes at C4 over an area of 500 m by 250 m; this has
tested only 3% of the 4 km2 core of the IP chargeability anomaly which remains to be fully drill tested.
Svea Target - Porphyry Cu – Au and Structurally Controlled Cu-Au-Mo
Ten scout core drill holes (2,772 m) were completed in 2024 on the Svea Target. Drilling at Svea was guided by the
interpretaVon of IP and aeromagneVc geophysics and broad historical Cu-Au soil geochemical anomaly, as well as
the results from a series of short, typically < 70 m long, historical drill holes completed in the late 1960’s and early
1970’s (see Amarc release January 19, 2024).
Drilling Highlights
• Select drill holes at Svea intersected Cu-Au mineralized zones comparable to those intersected in historical
drillholes, for example, drillhole DKS24046 intercepted 96 m of 0.23% CuEQ from 218 m, including a
higher-grade interval of 21 m of 0.39% CuEQ from 236 m.
• Quartz-bornite micro veinlets were encountered in two drill holes: DKS24049 intercepted 26 m of 0.23%
CuEQ from 4 m, and DKS24050 intercepted 12 m of 0.16% CuEQ from 5 m.
• Copper mineralized zones in several of the Svea drill holes have associated elevated Au concentraVons
ranging above 0.1 g/t Au. DDH’s DKS24046, DKS24049, DKS24052 and DKS24053 host intervals of greater
than 0.1 g/t Au over widths ranging from 8 to 24 m.
• Svea hosts a diverse suite of intrusions, which may be mineralized.

Notes to Table 1:
1. For inclusion in Table 1 all CuEQ values must exceed 0.14% CuEQ over greater then or equal to 12 m or gold assay
values exceeding 1.0 g/t Au over 3 m, except for holes DKJ24043 & DKS24049, which are calculated at 0.12% & 0.13% CuEQ,
respectively. Drillholes not listed, lie below these thresholds.
2. Widths reported are drill widths, such that true thicknesses are unknown.
3. All assay intervals represent length-weighted averages.
4. Some figures may not sum exactly due to rounding.
5. Copper equivalent (CuEQ) calculations use metal prices of: Cu US$4.00/lb, Au US$1,800.00/oz,
Ag US$24.00/oz and conceptual recoveries of: Cu 85%, Au 72% and Ag 67%. Conversion of metals to an
equivalent copper grade based on these metal prices is relative to the copper price per unit mass factored by
conceptual recoveries for those metals normalized to the conceptualized copper recovery. The metal
equivalencies for each metal are added to the copper grade. The general formula for this is: CuEQ % = Cu% + (Au
g/t * (Au recovery / Cu recovery) * (Au $ per oz/ 31.1034768) / (Cu $ per lb* 22.04623)) + (Ag g/t * (Ag recovery / Cu
recovery) * (Ag $ per oz/ 31.1034768) / (Cu $ per lb* 22.04623)).
The Company also announces that it has granted 100,000 options at a price of $0.68 per share with a five year
term to a senior executive.
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 its 100%-owned 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 important-scale, porphyry Cu±Au deposits. Importantly, each of
the three districts are located in proximity to industrial infrastructure – including power, highways and rail.
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 porphyry Cu-
Au-Ag Deposit.
Freeport-McMoRan Mineral Properties Canada Inc. ("Freeport"), a wholly owned subsidiary of Freeport-
McMoRan Inc. at JOY and Boliden Mineral Canada Ltd. ("Boliden"), an entity within the Boliden Group of
companies at DUKE, can earn up to a 70% interest in each District through staged investments of $110 million
and $90 million, respectively. Together this provides Amarc with potentially up to $200 million in non-share
dilutive staged funding for these Districts. In addition, Amarc completed self -funded drilling at its higher-
grade Empress Deposit in the IKE District in 2024. Amarc is the operator of all programs.
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, S isson, Maggie, AuRORA,
PINE, IKE and DUKE. From its head office in Vancouver, Canada, HDI applies its unique 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 engagem ent 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 partnerships
with Indigenous groups within whose traditional territories our projects are located, through the provision of
jobs, training programs, contract opportunities, capacity 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 NQ (47.6mm) size core in the summer of 2024. 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 Canada Ltd., Kamloops or
Langley, Canada, for preparation and to North Vancouver, Canada for analysis. All facilities are ISO/IEC 17025:2017
accredited. At the laboratory, samples were dried, crushed to 70% passing -2mm, and a 250 g split pulverized to
better than 85% passing 75 microns. Samples were analyzed for Au by fire assay fusion of 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 contr ol
samples were inserted in each analytical batch of the 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 proper QAQC.
