During the year ended November 30, 2023, the ARO for the Whistler Project was revised due to changes in the estimated timing of reclamation activities and updated assumptions regarding reclamation costs. The estimated future costs for the rehabilitation activities were updated for camp structures due to additional facilities constructed during the year and for the exploration and evaluation assets due to surface disturbance resulting from past exploration programs. The life expectancy of the ARO was extended to 10 years. The Company recorded a change in estimate to the ARO of $67,042, resulting in the corresponding camp structures being decreased by $98,434 (Note 6), and the exploration and evaluation assets being increased by $31,392 (Note 8), respectively.
