Streaming Transactions |
The Company bifurcates both streaming transactions | The Company bifurcates both streaming transactions in two identifiable components: (i) the sale of the mineral rights and (ii) extraction services. Sale of mineral rights – The amount allocated to this component is recognized as revenue in the income statement when the Company transfers ownership of the mineral rights to the counterparty. The cost related to the component sold is recognized in the income statement at the same moment. Extraction services – The Company recognizes contract liabilities in the event it receives payments from customers before a sale meets criteria for revenue recognition. Proceeds received under the terms of the streaming transaction allocated to this component are accounted for as “streaming transactions” and included within liabilities. Contract liability is initially recognized at fair value, net of transaction costs incurred, and is subsequently carried at amortized cost and updated using the effective interest rate method. Contract liability is released to the income statement based on the units of production, that is, revenue is calculated based on volume produced compared to the total proved and probable reserves of gold or cobalt, which are reviewed and remeasured annually. Critical accounting estimates and judgments Defining the result on sale of mineral interest and the contractual liabilities portion of the streaming transaction it is required the use of critical accounting estimates including, but not limited to: (i) allocation of costs between the product and the by-product based on relative prices; (ii) expected margin for the independent components (sale of mineral rights and service for gold and cobalt extraction); and (iii) discount rates used to measure the present value of future inflows and outflows.
