Provisional pricing adjustments on sales of concentrate consist of provisional and final pricing adjustments made prior to the finalization of the sales contract. The Company's sales contracts are provisionally priced with provisional pricing periods lasting typically one to three months with provisional pricing adjustments recorded to revenue as market prices vary. As at December 31, 2021, a 10% change to the underlying metals prices would result in a change in revenue and accounts receivable of $470 (December 31, 2020 - $716) based on the total quantities of metals in sales contracts for which the provisional pricing periods were not yet closed.
