Purchases and sales of lithium carbonate During the year ended December 31, 2025, the Company was entitled to purchase its 49% share of Minera Exar’s lithium carbonate production shipped during the period and, pursuant to its offtake agreements, sell that volume to Ganfeng and Bangchak. Based on its principal versus agent assessment, the Company concluded that it acted as an agent in these transactions, as control of the lithium carbonate did not transfer to the Company prior to transfer to the end customers and the Company was not exposed to inventory or price risk.

Since there was no net commission earned by the Company, there was no impact on the Company’s statement of comprehensive loss for the year ended December 31, 2025. As at December 31, 2025, the Company had a payable of $25,507 to Minera Exar for lithium carbonate purchases, and receivables totaling $23,209 from Ganfeng for sales of lithium carbonate, as disclosed on the statement of financial position. The Company performed an expected credit loss assessment for these receivables, and concluded that the expected credit loss was insignificant, given the short-term nature of the balances and the counterparties' history of timely settlement. The receivables were fully settled subsequent to December 31, 2025.
