Amarc Joy District Drilling Significantly Expands Pine Cu-Au Deposit and Makes Important New Discovery at Canyon

VANCOUVER, BC / ACCESSWIRE / March 2, 2023 / Amarc Resources Ltd. ("Amarc" or the "Company") (TSXV:AHR)(OTCQB:AXREF) is pleased to announce the results of 2022 drilling at the PINE Deposit, and from scout drilling at prioritized porphyry copper-gold ("Cu-Au") deposit targets clustered across its 482 km², 100%-owned JOY District (or "JOY"), in north-central British Columbia ("BC"). During the 2022 season Amarc completed 37 core holes (15,427 m) that considerably expanded the PINE Deposit to over a 1,700 m strike length, discovered new porphyry Cu-Au mineralization at the 5 km² Canyon deposit target, and further defined additional deposit-scale porphyry systems requiring exploration drilling.

Over the past two years, Freeport-McMoRan Mineral Properties Canada Inc. ("Freeport"), which is earning-in at JOY, has invested approximately $20 million advancing exploration programs (see Amarc release October 11, 2022). Amarc is operator of the project.

Highlights from 2022 PINE Deposit Drilling Include:

• 204 m of 0.42% CuEQ* (0.18% Cu, 0.41 g/t Au and 2.3 g/t Ag)
• 105 m of 0.40% CuEQ (0.13% Cu, 0.47 g/t Au and 2.3 g/t Ag)
• 107 m of 0.31% CuEQ (0.09% Cu, 0.37 g/t Au and 1.2 g/t Ag)
• 179 m of 0.32% CuEQ (0.11% Cu, 0.36 g/t Au and 1.2 g/t Ag)

Highlights from New Porphyry Cu-Au Discovery at Canyon Deposit Target Include:

• 96 m of 0.51% CuEQ (0.39% Cu, 0.18 g/t Au and 2.6 g/t Ag), within
• 296 m of 0.39% CuEQ (0.30% Cu, 0.14 g/t Au and 1.7 g/t Ag)

*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 67% Ag.

"The strong results delivered by our 2022 drilling continue to reveal the exceptional potential of the JOY District,"said Dr. Diane Nicolson, Amarc President and CEO. "Delineation drilling at the PINE Deposit substantially expanded mineralization and it is still wide open. In addition, scout drilling of expansive deposit scale targets is confirming the potential for clustered porphyry mineralized deposits around the PINE: the discovery of new copper-gold mineralization at the largely covered Canyon target is especially exciting. Also, as previously reported surface surveys are preparing new and compelling porphyry copper-gold deposit targets across JOY for drilling."

Nicolson said that having recently received and verified all drill results, Amarc is currently in the process of fully integrating all drill core assay details with extensive surface surveys, to complete 2023 program planning with Freeport.

Expansion of the PINE Porphyry Cu-Au Deposit Over 1,700 m of Strike Length

Prior to 2022, drilling the PINE Deposit was, from Amarc's and historical drilling, known to extend over approximately 600 m by 900 m; importantly, it was also recognized to be open to expansion internally and laterally as well as to depth (see Amarc release March 7, 2022). In 2022, the 11 core holes (up to 781 m in length) completed at PINE successfully intercepted significant mineralization that extended the footprint of the deposit over a strike length of 1,700 m (Tables 1 and 2, Figures 1 and 2). Furthermore, outboard, wider spaced and mainly historical drilling indicates the potential to expand this footprint to over 2,600 m. Additionally, drilling is highlighting the favorable geometry of the PINE Deposit, with the majority of known mineralization occurring from surface to 300 m depth, and locally extending to 550 m depth. The PINE Deposit and its expansion potential are hosted within a larger 6 km² mineralized system, which also remains to be fully explored.

Notably, additional centers of higher Cu-Au grade are beginning to emerge along the 1,700 m PINE Deposit trend. For example, Amarc drilling in the northeastern area of this trend has intersected significant porphyry mineralization over 600 m of strike length, including:

• 63 m of 0.44% CuEQ, within 179 m of 0.32% CuEQ (JP22017)
• 57 m of 0.40% CuEQ, within 107 m of 0.31% CuEQ (JP22015)
• 135 m of 0.44% CuEQ, within 244 m of 0.35% CuEQ (JP21009 completed in 2021)

Notes:

1. Widths reported are drill widths, such that true thicknesses are unknown.
2. All assay intervals represent length-weighted averages.
3. Some figures may not sum exactly due to rounding.
4. Copper equivalent (CuEQ) calculations use metal prices of: Cu US$4.00/lb., Au US$1800/oz. and Ag US$24/oz. and conceptual recoveries of: Cu 85%, Au 72% and 67% Ag. 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))

Discovery At Canyon Deposit Target Highlights Potential for Clustered Deposits at JOY

Eight extensive porphyry Cu-Au deposit targets were explored with 26 scout drill holes in 2022, including four targets that had not previously been drill tested. These deposit targets include the Canyon (5 km²), Twins (7 km²) and SWT (3 km²) which along with PINE (6 km²) form the 15.5 km northeast trending PINE Trend, and the South Mex (>1.9 km²) open deposit target at the south end of the 6 km-long MEX Trend (see Amarc's January 23, 2023 news release) (Figures 3 and 4). These trends are similar to the 4 km-long northeast trend of the Nugget, Kemess North, Kemess Underground, Kemess Offset and Kemess East porphyry Cu-Au deposits in the Kemess Mining District held by Centerra Gold Inc., located adjacent to the south of the JOY tenure.

At Canyon very limited initial scout drilling of this expansive (5 km²) and largely covered sulphide system by Amarc in 2021 (JP21006: 27 m of 0.18% CuEQ with 0.06% Cu, 0.21 g/t Au) (see Amarc news release March 7, 2022) and historical operators (MEX12-013: 49 m of 0.16% CuEQ with 0.05% Cu, 0.20 g/t Au, and PIN09-15: 3 m of 11 g/t Au), intersected promising Cu-Au and Au-only mineralization compatible with the fringes of a potentially important porphyry Cu-Au system. In 2022, further reconnaissance drilling at Canyon discovered a significant new zone of porphyry Cu-Au mineralization with hole JP22030 intersecting:

• 96 m of 0.51% CuEQ (0.39% Cu, 0.18 g/t Au and 2.6 g/t Ag), within
  296 m of 0.39% CuEQ (0.30% Cu, 0.14 g/t Au and 1.7 g/t Ag)
• 10.5 m of 0.77% CuEQ (0.61% Cu, 0.25 g/t Au, 2.1 g/t Ag)

Four other scout drill holes intersected less robust Cu-Au mineralization disrupted by inter-mineral intrusions. The Canyon discovery remains open to expansion and requires substantial drilling, as does the host 5 km² IP geophysical anomaly which indicates the presence of a large-scale sulphide system.

Figure 5: Canyon Deposit Target - New Discovery Validates Systematic Exploration Strategy

The highly prospective Twins (7 km²) deposit target is located adjacent and to the southwest along the 15.5 km PINE Trend from Canyon. A single scout drill hole completed by Amarc in 2021 (JP21004), the first ever drilled into the large Twins target, intersected 63 m of 0.18% CuEQ with 0.09% Cu, 0.15 g/t Au, 0.5 g/t Ag, including 39 m of 0.22% CuEQ with 0.11% Cu, 0.19 g/t Au, 0.6 g/t Ag, successfully discovering porphyry-type Cu-Au mineralization (see Amarc release March 7, 2022) within this large mineralized sulphide system. In 2022, very widely-spaced follow-up reconnaissance drill holes, ranging in length from 216 m to 384 m, targeted magnetic high features within the extensive IP chargeability footprint (Figure 3) and encountered widespread indications of porphyry Cu-Au mineralization.

Based on comparisons with the Canyon discovery and the PINE Deposit, intervals of porphyry Cu-Au mineralization including 27 m of 0.29% CuEQ (0.12% Cu, 0.30 g/t Au, 1.2 g/t Ag) in JP22019 and 204 m of 0.11% CuEQ (0.04% Cu, 0.14 g/t Au, 0.4 g/t Ag) in JP22020, may represent the lateral or upper parts of a yet undiscovered porphyry Cu-Au center. The large footprint of this target, its veneer of glacial overburden cover, and Cu-Au intercepts in the widely spaced and relatively shallow drill holes highlight the significant exploration potential for the discovery of another porphyry Cu-Au deposit at Twins.

Systematic Exploration of Emerging Deposit Targets

A similar strategy of initial drill testing with single to widely spaced shorter scout drill holes was employed at other overburden-covered targets, including South MEX, South Finlay, North Finlay and CT, with results indicating continued systematic exploration is warranted. At South MEX, a single scout drill hole, the first in this >1.9 km² IP chargeability anomaly which remains open to expansion, intersected anomalous Au-Cu-Ag (72 m of 0.10% CuEQ (0.02% Cu, 0.10 g/t Au, 3.4 g/t Ag) in JP22041) in volcanics that straddle the prospective Triassic-Jurassic contact: a geological environment similar to that hosting the Kemess District porphyry Cu-Au deposits (see Amarc release January 23, 2023).

Scout drilling at SWT returned local zones of anomalous Au-Cu compatible with proximity to a porphyry Cu-Au system (e.g. 78 m of 0.09% CuEQ (0.02% Cu, 0.11 g/t Au, 0.04 g/t Ag) in JP22028), as well as local vein-hosted Au-only mineralization (2.7 m of 3.7 g/t Au in JP22024). At the adjacent Wrich occurrence, Au-Ag-Cu mineralization (108 m of 0.20% CuEQ (0.03% Cu, 0.23 g/t Au, 6.4 g/t Ag) in JP22044) is associated with advanced argillic alteration zones and may represent a higher-level signature of a porphyry Cu-Au system.

About the JOY District

Amarc's 100%-owned JOY District is located on the northern extension of the prolific Kemess porphyry Cu-Au District that includes the former Kemess South mine, the permitted and development-stage Kemess North underground deposit, and the advanced-stage Kemess East underground deposit - all currently held by Centerra Gold Inc. Through its association with Hunter Dickinson Inc., Amarc's technical team was first to recognize the Kemess District's true porphyry potential, acquiring Kemess North and Kemess South as early-stage prospects and advancing both to significant porphyry Cu-Au deposits. Kemess South was sold in 1996 on beneficial terms to a predecessor of Northgate Minerals, which brought that deposit into production.

The JOY District is readily accessed via resource roads servicing the southern end of the Toodoggone region, including Centerra's Kemess porphyry Cu-Au deposits and the historical Lawyers, Baker and Shasta epithermal precious metal mines now being redeveloped by Benchmark Metals Inc. and TDG Gold Corp, respectively.

In May 2021, Amarc entered into a Mineral Property Earn-In Agreement (the "EIA") with Freeport-McMoRan Mineral Properties Canada Inc. ("Freeport"), a wholly owned subsidiary of Freeport-McMoRan Inc. (see Amarc release May 12, 2021). Freeport may acquire up to a 70% ownership interest in JOY by making staged investments totally $110 million.

In 2021, Freeport contributed $5.94 million to the Year 1 JOY exploration program and approximately $14 million in 2022 as its Year 2 investment (see Amarc releases November 15 and December 15, 2021).

Further in-depth information on historical and more recent exploration activities completed within the JOY District prior to 2021 can be found in the Company's 'JOY Project 2020 Technical Report', filed under Amarc's profile at www.sedar.com or located on its website at https://amarcresources.com/projects/joy-project/technical-report/.

Quality Control/Quality Assurance Program

Amarc drilled mostly NQ size core in 2022, except in the PINE Deposit area where the holes were drilled HQ core size and then reduced to NQ, typically around 200 m depth, to hole completion. Overall, 12% of the 2022 core drilled was HQ size. All drill core was logged, photographed, and cut in half with a diamond saw. Half core samples from JOY were sent to Activation Laboratories Ltd. (Actlabs), Kamloops, Canada facility for preparation and analysis. During peak periods, samples were also prepared at Actlabs laboratories located in Timmins and Ancaster, Ontario.

At the preparation laboratory, the entire sample was dried, crushed to 80% passing 2 mm size, mechanically split (by riffle) to obtain a representative sample and then pulverized to at least 95% minus 105 microns (μm) (method RX1). The pulverized fraction was analyzed for Au at either the Actlabs, Kamloops, Timmins or Ancaster laboratory by fire assay fusion of a 30 g sub-sample with an ICP-OES finish (method 1A2-ICP). All samples were also analyzed with a multi-element ICP finish. In this method, Cu, Ag and 58 additional elements were determined by 4-acid digestion of a 0.25 sub-sample followed by an ICP-OES and ICP-MS finish (method UT6). Samples >10,000 ppm Cu by UT6 were also analyzed by assay grade 4-acid digestion ICP-OES. All multi-element and Cu ICP analysis was done at the Ancaster facility.

The three Actlabs facilities are ISO/IEC 17025 accredited. As part of a comprehensive Quality Assurance/Quality Control ("QAQC") program, Amarc control samples were inserted in each analytical batch at the following rates: standards one in 20 regular samples, coarse reject duplicate splits one in 20 samples and blanks one in 80 regular samples, or once per drill hole. The control sample results were then checked to ensure proper QAQC.
