  Drill hole JP24057 interval 166-169 m comprised broken ground, no core was recovered, and it was therefore averaged at zero grade.                                                                    
  Drill hole JP24071 interval 179-182 m comprised broken ground, no core was recovered, and it was therefore averaged at zero grade.                                                                    
  Drill hole JP24076 intervals 72-75 m, 78-81 m and 96-102 m comprised broken ground, no core was recovered, and each was therefore averaged at zero grade.                                             
  Drill hole JP24084 interval 201-207 m comprised broken ground, no core was recovered, and it was therefore averaged at zero grade.                                                                    

QAQC: Amarc drilled NQv (48.1mm) and HQ (63.5mm) size core in 2024 at the JOY project. All drill core was logged, photographed, and cut in half with a diamond saw. Half core samples from the JOY drilling 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 either a 250 g split or 1,000 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 60 elements including Cu, Mo and Ag by a four-acid digestion, multi-element ICP-MS package. Samples with Cu results > 10,000 ppm were reanalyzed by a single element four-acid digestion ICP-AES method for Cu. As part of a comprehensive Quality Assurance/Quality Control (“ QAQC”) program, Amarc control samples were inserted in each analytical batch of the core samples at the following rates: standards one in 20 regular samples, in-line replicates one in 20 regular samples and one coarse blank per hole. The control sample results were then checked to ensure proper QAQC.

The QP visited the site to verify location of drill holes, and review the core and logging, sampling and sample shipment processes. He also reviewed and assessed the assay results.
