VANCOUVER, BC / ACCESSWIRE / January 23, 2023 / Amarc Resources Ltd. ("Amarc" or the "Company") (TSX-V:AHR)(OTCQB:AXREF) is pleased to announce the identification of new, and the expansion of known, porphyry copper-gold ("Cu-Au") deposit drill targets across its 482 km2, 100%-owned JOY District (or "JOY"), in north-central British Columbia ("BC"). These targets are defined based on the integration of comprehensive geophysical, geochemical and geological field survey work, combined with extensive historical survey results completed by past operators. Over the past two years, Freeport-McMoRan Mineral Properties Canada Inc. ("Freeport"), which is earning-in at JOY, has invested approximately $20 million towards advancing the exploration program (see Amarc release October 11, 2022). Amarc is operator of the project.
Amarc continues to receive incoming drill assay results from the laboratory for 37 core holes (15,427 m) completed in 2022. It is expected all drill results will be received and compiled over the next few weeks and reported as soon as possible.
"Our systematic surface survey results from 2022 have continued to identify significant new porphyry copper-gold deposit targets across JOY that have not yet been drill tested, while further refining existing deposit targets along major structural trends," said Dr. Diane Nicolson Amarc President and CEO. "We believe there is a real opportunity to make multiple, important scale copper-gold deposit discoveries, as we work with Freeport to progress these targets and fully develop the District."
IP Geophysical Surveys
Integration of 56.3 new line-km of Induced Polarization ("IP") ground geophysical surveys from 2022 with the 154 line-km previously completed by Amarc, and the approximately 150 line-km completed historically by Gold Fields Limited continues to discover and expand clusters of large sulphide-bearing hydrothermal systems. These systems host or have significant potential to host porphyry Cu-Au systems, and are principally aligned along a 12.5 km northeast trending corridor. This corridor includes the PINE mineral system which measures 6 km2 and is host to the PINE Deposit (see Amarc release March 7, 2022), and the Canyon (5 km2), Twins (7 km2) and SWT (3 km2) deposit targets (Figure 1). This trend is similar to the northeast trend of the Nugget, Kemess North, Kemess Underground and Kemess East Cu-Au porphyry deposits in the Kemess Mining District, which is located adjacent to the south of the JOY tenure and held by Centerra Gold Inc.
In addition, a second prospective mineralized corridor is defined by a series of IP chargeability anomalies that extend north-northeast over approximately 6 km and remains open to expansion (Figure 1). The corridor includes the More MEX, North MEX, MEX and South MEX deposit targets (see Amarc's JOY 2020 Technical Report as referenced below). The MEX deposit target is known to host porphyry Cu-Au mineralization, and all targets on this trend remain to be fully explored.
Furthermore, the NW Gossan (>2.2 km2), South MEX (>1.9 km2) and SWT (3 km2) represent significant newly discovered sulphide systems which remain open to expansion.
Soil Geochemistry Survey
The 2022 soil geochemical survey (2,468 samples collected) has delineated encouraging new Cu-Au and multielement anomalies, which are in addition to those outlined by previous soils analyses by Amarc and historical operators (10,957 samples) across the JOY District (Figures 2 and 3). Collectively these multielement anomalies are characteristic of porphyry Cu-Au, transitional porphyry-epithermal and epithermal Au-Ag systems. Newly emerging geochemical anomalies include those at the NW Gossan,South MEX, Acapulco, WT, NWT and Jock deposit targets; these targets remain open to expansion and drill testing.
Developing Porphyry Cu-Au Deposit Targets
Emerging and established, high-potential deposit scale targets at JOY occur in areas known or inferred to be underlain by highly prospective Middle Triassic to Lower Jurassic rocks of the Stikine Terrane, and are spatially associated with a significant regional Triassic-Jurassic unconformity (~200 Ma) age. This important geological environment extends throughout the well-endowed Golden Horseshoe Trend, including in the Golden Triangle and is host to world class Cu-Au deposits such as Galore Creek, Kerr-Sulphurets-Mitchell (KSM) and Red Chris. Geological work in 2022 has confirmed that the emerging NW Gossan, South MEX, SWT, WT, NWT and Jock deposit targets are optimally located within this geological environment.
Notably, in addition to being located in a highly favorable geological environment, the emerging NW Gossan deposit target is characterized by a newly delineated 4 km2, Au-Cu-Mo-Ag-As-Pb-Se-Te-Bi soil geochemical anomaly. This geochemical signature is compatible with the peripheries of a porphyry Cu-Au(-Mo) system, and coincides with a new and substantial IP chargeability anomaly that remains open to expansion (Figures 1, 2 and 3). This new deposit target remains to be explored with additional surface surveys and has not been drill tested.
Exploration Under Cover: Canyon and Twins Deposit Targets
Some of the most significant deposit targets at JOY are in topographically subdued areas characterized by a relatively thin veneer (~2-40 m) of glacially transported overburden cover. In this environment both soils geochemical and geological expressions of potential concealed mineralization can be extremely muted and, as such, these largely covered targets have significant and previously underappreciated discovery upside potential. Located within a low-lying and gently undulating area of topography, the PINE Deposit, which is being systematically delineated by Amarc, notably has little or no soils geochemical signature directly overlying the Cu-Au mineralized porphyry body (Figures 2 and 3), the geochemical signature having been transported some 2 km down ice to the northeast. Similarly, the Canyon and Twins deposit targets are largely glacial overburden covered and have subdued soil geochemistry but have strong potential to host concealed porphyry Cu-Au deposits.
At Canyon, limited initial scout drilling of this expansive sulphide system by Amarc in 2021 (JP21006: 27 m of 0.18% CuEQ1 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% CuEQwith 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 significant porphyry Cu-Au system.
The 2022 IP survey at Twins extended its highly prospective chargeability anomaly to 7 km2, which remains open to further expansion to the east. A single scout drill hole completed by Amarc in 2021 (JP21004), the first ever drilled into the sizable Twins target, intersected 63 m of 0.18% CuEQ1 with 0.09% Cu, 0.15 g/t Au, 0.5 g/t Ag, including 39 m of 0.22% CuEQ1 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).
1 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 Mo US$15.00/lb and conceptual recoveries of: Cu 85%, Au 72%, 67% Ag and Mo 82%. The estimated metallurgical recoveries are conceptual in nature. There is no guarantee that the metallurgical testing required to determine metal recoveries will be done or, if done, the metallurgical recoveries could be the same as the conceptual recoveries used to determine the CuEQ.
About the JOY District
Amarc's 100%-owned JOY District is located on the northern extension of the prolific Kemess porphyry Cu-Au District, which 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).
In 2021, Freeport contributed $5.94 million to the Year 1 JOY exploration program and approximately $14 million in 2022 as its Year 2 spend (see Amarc releases November 15 and December 15, 2021).
Further in-depth information on historical and contemporary 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
Soil samples were sent to Activation Laboratories Ltd. (Actlabs), Kamloops, Canada facility for preparation and analysis. At Actlabs Kamloops, samples were dried at 60°C and sieved to -177 μm (-80 mesh). The -80 mesh fraction for all sample was analyzed for Au at Actlabs Kamloops by fire assay fusion of a 30 g sub-sample with an ICP-OES finish. All samples were also analyzed by multi-element ICP methods. Samples on soil lines in new exploration areas were analyzed for Cu, Ag and 58 additional elements by 4 acid digestion of a 0.25 sub-sample followed by an ICP-OES and ICP-MS finish. Approximately 7% of the samples were taken on extensions of earlier grids. These samples were analyzed for Cu, Au, Ag and 60 additional elements by Aqua Regia digestion of a 0.5 g sample followed by an ICP-MS finish to match the analytical method employed on these grids. All multi-element ICP analysis was done at the Actlabs Ancaster Ontario facility. Both 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 soil sample analytical batch at the following rates: standards and/or blanks one in 80 regular samples. The control sample results were then checked to ensure proper QAQC.
