Amarc and Freeport Continue Expanding High Grade Aurora Copper-Gold-Silver DepositDeposit Remains Open - Further Assays Pending VANCOUVER, BC / ACCESS Newswire / December 10, 2025 / Amarc Resources Ltd. ("Amarc" or the "Company") (TSXV:AHR)(OTCQB:AXREF) is pleased to announce additional assay results from the 2025 JOY District drill program. The completed 2025 drill program was primarily focused on continuing to define the full extent of the AuRORA Deposit discovered later in 2024. The AuRORA Deposit hosts high grade near surface, copper-gold-silver ("Cu-Au-Ag") mineralization with exceptional vertical and lateral continuity (see Amarc releases January 17, 20 and February 28, 2025) and remains open to further expansion to the north, east and west. Amarc believes the rare contribution of grade, geometry and emerging scale of AuRORA indicates it has the hallmarks of a Tier One asset in the making.Twenty-four core holes (9,687 m) were completed at the AuRORA Deposit in 2025; 23 of these are expansion step-out holes drilled over an area measuring some 1 km by 1 km. Host rocks, alteration and mineralization remain consistent with that encountered in the 2024 AuRORA discovery drill holes.Results announced in November from six holes completed on Sections 8000N and 8100N successfully expanded AuRORA +200 m to the north (see Amarc release October 22, 2025). Today, we are announcing two drill holes (JP25103, JP25109) located on Section 8200N, which have expanded AuRORA a further +100 m to the north (Figures 1, 2, 3 and 4, and Tables 1 and 2).In addition, assay results are also being released for two new holes completed on Section 7900N (JP25093 and JP25107) which expand the deposit approximately 200 m to the east (Figures 1 and 5, and Tables 1 and 2). Today's results also include the balance of hole JP25098 on Section 7600N (partially announced in September) that expanded the deposit approximately 300 m to the southeast (see Figures 1 and 6 and Tables 1 and 2). Assay results from four 2025 step-out holes on this section are still pending.Highlights from Drill Holes Located on Sections 7900N and 8200N at AuRORA Include:201 m of 1.40 g/t Au, 0.28% Cu and 2.6 g/t Ag including32 m of 1.65 g/t Au, 0.27% Cu and 2.0 g/t Ag and94 m of 2.08 g/t Au, 0.41% Cu and 3.4 g/t Ag201 m of 1.38 g/t Au, 0.27% Cu and 1.6 g/t Ag including135 m of 1.90 g/t Au, 0.30% Cu and 1.6 g/t Ag and111 m of 2.24 g/t Au, 0.34% Cu and 1.6 g/t Ag 47 m of 1.50 g/t Au, 0.44% Cu and 5.4 g/t Ag"We are very excited by the significant expansion potential of the AuRORA Deposit which stands out as it includes some of the highest porphyry grades ever intercepted in the Province," said Amarc's President and CEO, Dr. Diane Nicolson. "We believe that the AuRORA discovery with substantial Freeport funding has the potential to unlock the emergence of a world class porphyry copper-gold district in the Toodoggone region that has many geological similarities to British Columbia's renowned Golden Triangle. With the recent TWINS and Canyon Discoveries, further potential at PINE and Brenda historical deposits and emerging new deposit targets yet to be fully explored across the entire 630 km2 JOY District, there is clearly a lot more to come." AuRORA drilling in 2024-2025 now totals 45 drillholes (17,586 m). Assay results from the total 35 holes drilled (15,381 m) across the JOY District in 2025 are being received and planned to be released in batches going forward.An overview of AuRORA Deposit is one of the highlights of Amarc's updated website, recently launched at www.amarcresources.com.Figure 1 (Drill Plan Map): AuRORA Deposit Discovery High Grade Near Surface, Exceptional Continuity, Deposit Continues to be Open to ExpansionFigure 2 (Section 8200N): AuRORA Deposit Discovery 2025 Step-Out Drilling is Discovering More Open-Ended, Continuous MineralizationFigure 3: AuRORA Deposit Discovery Section 8100NFigure 4: AuRORA Deposit Discovery Section 8000NFigure 5: AuRORA Deposit Discovery Section 7900NFigure 6: AuRORA Deposit Discovery Section 7600NTable 1: AuRORA Porphyry Cu-Au-Ag Deposit Expansion Drilling Sections 8200N, 7900N and 7600NSectionDrill HoleIncl.From (m)To (m)Int.1,2,3(m)Au (g/t)Cu (%)Ag (g/t)8200NJP25103 42.0043.801.800.030.45999.0 329.00376.2847.281.500.445.4 JP25109 220.00420.95200.951.380.271.6 4 Incl.286.00420.95134.951.900.301.6 and286.00397.00111.002.240.341.67900NJP25093 84.00204.00120.000.280.30 53.5 Incl.102.00204.00102.000.310.303.6 238.00249.0011.000.440.304.0 JP25107 21.00222.00201.001.400.282.6 Incl.30.0062.0632.061.650.272.0 Incl.70.85165.0094.152.080.413.47600NJP25098 202.00440.10238.10.400.254.3 Incl.253.00412.00159.000.430.335.1 and356.65412.0055.350.540.354.7 and356.65375.0018.350.580.436.2Notes to Table 1:Widths reported are drill widths, such that true thicknesses are unknown.All assay intervals represent length-weighted averages.Some figures may not sum exactly due to rounding.Values rounded to one decimal place; underlying results for Ag (g
