Historical drilling encountered significant 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. 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. For further information on historical drilling at Empress, see Amarc’s 2024 Form on 20F.

The 2024 work comprised two principle and supporting activities including 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.

Key results of the 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 histo...

Amarc also drilled nine holes in the Greater Empress Area in 2024 to confirm the strength, continuity and form of the historically identified well Cu-Au mineralized intersections at the Empress Deposit and Empress East Deposit Target. Six of the eight drill holes collared at the Empress Deposit intercepted significant Cu-Au mineralized zones, including
