 fire assay results.

Assay data for approximately 5,643 samples from short percussion and core holes drilled in the Greater Empress Area (i. e. Empress Deposit, and the Empress East, Empress Gap and Empress West Deposit Targets) are available. Gold assays are partially absent from the historical database (i. e. partially absent for years 1969, 1976, 1981 and completely absent for years 1965, 1970, & 1971), and only Cu and Mo assays are available from the percussion holes, analyzed using a wide range of methods. Of the original historical samples, 90% were analyzed by VanGeochem and 10% by an unknown laboratory. These results and diverse geological interpretations from the historical drill holes were assessed and validated by Amarc.

A total of 27 historical holes were re-logged by Amarc, including 21 holes from the Empress Deposit, 3 holes from Empress East Deposit Target and 1 hole from each of the Empress West, Empress Gap and Granite Targets. Of the 27 historical core holes previously drilled in the Greater Empress Area, a total of 23 drill holes were selected for the re-sampling and re-assaying program. The re-sampling of the historical core involved 4 primary collection methods: 1. total utilization of the remaining half-core splits; 2. whole core sampling of intervals that were not originally sampled; 3. total utilization of every alternate down-hole core segment (i. e. being either half or full core); and 4. utilization of coarse rejects of crushed half core that was prepared and left on site by the original operators. The 2024 re-sampling of the historical core sample intervals were matched as closely as possible but was subject to minor interval discrepancies due to varying states of preservation of the historical core and original depth markings.

All 2024 core samples were sent to ALS Canada Ltd., Kamloops or Langley, Canada, for preparation and to North Vancouver, Canada for analysis. All facilities are ISO/IEC 17025:2017 accredited. At the laboratory, samples were dried, crushed to 70% passing -2mm, and a 250 g split was pulverized to better than 85% passing 75 microns. Samples were analyzed for Au by fire assay fusion of a 30 g sub-sample with an ICP-AES finish, and for Cu, Ag and 58 additional elements by a 4-acid digestion
