Fair Value

Financial instruments recorded at fair value on the consolidated statement of financial position are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:

a) Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities;

b) Level 2 - Inputs other than quoted prices that are observable for assets or liabilities, either directly or indirectly; and

c) Level 3 - Inputs for assets and liabilities that are not based on observable market data.

The fair value hierarchy requires the use of observable market inputs whenever such inputs exist. A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring fair value.

Cash, accounts receivables (royalty, and stream receivables, and other receivables), and accounts payable (trade and other payables), are carried at amortized cost. Their carrying value approximated their fair value because of the short-term nature of these instruments or because they reflect amounts that are receivable to the Company without further adjustments. Marketable securities are carried at fair value and are classified within Level 1 of the fair value hierarchy. There were no transfers between the levels of the fair value hierarchy during the six months ended June 30, 2025, and the year ended December 31, 2024.
