(i) In December 2023, the Company disposed of its entire investment in Osisko Mining Inc. ("Osisko Mining").

(ii) The net share of income or loss is adjusted to the extent that management is aware of material events that affect the associates' net income or loss during the period.

(iii) In 2023 and 2022, the loss and gain on deemed disposals are related to investments in associates that were transferred to other investments as the Company has considered that it has lost its significant influence over these investees.

(iv) In 2023, the Company recorded an impairment charge on its investments in associates of $64.8 million, including $64.5 million on its investment in Osisko Development. The impairment resulted from, amongst others, the significant decrease in Osisko Development's share price, the deterioration of market conditions and the general negative sentiment towards exploration and development companies. The Company estimated the recoverable amount of its investment at $115.7 million, using a fair value less costs of disposal model with reference to Osisko Development's share price quoted on active markets, which is considered a Level 1 input. The Company estimated the cost of disposal using historical discounts and transaction fees for similar transactions.
