VANCOUVER, BC / ACCESS Newswire / May 14, 2025 / Amarc Resources Ltd. ("Amarc" or the "Company") (TSXV:AHR)(OTCQB:AXREF) is pleased to announce the results from its comprehensive, late 2024 exploration program at its 100% owned, 500 km ² IKE Copper-Gold ("Cu-Au") District, located in southern British Columbia ("BC"). The program focused on the higher grade Cu-Au mineralization discovered by historical operators within the Greater Empress Area which is a sizable subarea within the overall IKE District. The style and form of mineralization at Empress is unique within the western Cordillera with the initial technical data suggesting the centre of this robust mineralized Au-Cu system has not yet been defined. Greater Empress is located 6 km north of the Company's substantial IKE porphyry copper-molybdenum-silver ("Cu-Mo-Ag") discovery (Figure 1, and November 6, 2018 release). The 2024 program successfully confirmed high potential for the expansion of mineralization found historically at Empress and the discovery of additional higher grade intrusion-related replacement and porphyry Cu±Au±Mo±Ag deposits. Management considers the IKE District to be one of the prolifically mineralized belts in BC.

"At IKE, Amarc's team is in the privileged position of focusing our exploration towards multiple, open-ended historical deposits and targets with elevated copper and gold grades, in addition to multiple porphyry copper±gold±molydenum±silver and epithermal gold-silver deposit targets within the Greater Empress Area and across the IKE District," said Dr. Diane Nicolson, Amarc President and CEO.

"The hallmark of these mineral systems is their abundance as well as the size and strength of their alteration and metal signatures, which collectively have the potential to establish the IKE District as a premier mineral district. The 2024 program marked Amarc's successful initial testing of the higher grade Empress copper-gold potential along a 15 km+ highly prospective corridor within the IKE District. Amarc is currently integrating this new data with extensive previous airborne, and ground survey and drill information to plan further drilling programs to efficiently advance the Greater Empress Area and the overall IKE District."

Nicolson added, "In addition to IKE, Amarc is also effectively advancing the DUKE Cu-Au District (Babine Region) and JOY Cu-Au District (Toodoggone Region) in BC. Notably, Amarc recently announced the discovery of the exciting high grade, from surface AuRORA Cu-Au-Ag Deposit at JOY (January 17, 2025 release)."

The Significant Exploration Potential of the Greater Empress Area

The Greater Empress Area straddles the contact of the intrusive rocks of the Coast Plutonic Complex ("CPC") with older volcanic rocks to the north over a strike length of more than 15 km in the IKE District. Strong and widespread alteration with abundant sulphides along this contact are associated with a variety of deposit types, alteration assemblages, including Cu-Au-Ag replacement deposits such as Empress and Empress East, porphyry Cu±Au±Mo±Ag occurrences and high sulphidation epithermal Au-Ag systems (see 2020 IKE Technical Report https://amarcresources.com/projects/ike-project/technical-report/).

Historical drilling encountered significant higher grade Cu-Au-Ag replacement-style mineralization at the Empress Deposit hosted by altered volcanics, commonly occurring near the surface and predominantly within 100 m vertically above the contact of the CPC intrusive rocks with the overlying volcanics (Figures 2, 3 and 4). More limited historical drilling at the Empress East Deposit Target, some 1.3 km to the east, intercepted mineralization similar in both style and grade to the Empress Deposit.

Although the grades and extents of the mineralization encountered so far indicate high potential at Greater Empress, the understanding of controls on the mineralization is advancing, and has confirmed the area remains substantially underexplored.

Amarc's 2024 Greater Empress Area Exploration Program

Amarc's exploration program focused on the Empress Deposit and Empress East Deposit Target within the Greater Empress Area at which historical drilling had encountered higher grade Cu-Au mineralization. The 2024 work comprised two principle and supporting activities:

• the geological re-examination (4,610.7 m in 27 drill holes) and resampling for analyses (1,541 samples from 23 holes) of historical drill core; and

• selected diamond drill testing on broad centres in nine (1,873 m) new core holes of targets within the Empress Deposit and Empress East Deposit Target to determine the strength, continuity and form of the historically identified strong Cu-Au mineralization (Figures 2 and 3).

Re-Assaying and Geological Re-Logging of Historical Core Holes at the Empress Deposit and Empress East Deposit Target, and other Targets Within the Greater Empress Area

Key results of this re-assaying and re-logging program include:

• Approximately 29% of all available drill core was re-assayed with a majority of the historical assays showing strong positive correlations with the 2024 re-assay data, indicating that the historical database may be meaningfully integrated into future modelling and resource estimation;

• Re-logging revealed a style and form of mineralization characterized by: (i) stacked significant grade Cu-Au, magnetite-silica replacement bodies within the volcanics; and (ii) thick, well mineralized porphyry-style Cu-Au-Mo intrusive-hosted zones; and

• A new appreciation of the importance of structural controls on the development of higher-grade mineralized zones in the Empress replacement magnetite-silica bodies which provides a significant opportunity to build resources.

Table 1 presents the results from Amarc's re-assaying of historical core holes. The location of historical drill holes and those that were re-assayed, is shown in Figure 2. Additional information on the comparability of historical assays to the 2024 re-assays is provided below in the Quality Control/Quality Assurance section of this release.
