5. | SIGNIFICANT JUDGMENTS, ESTIMATES AND ASSUMPTIONS
The preparation of the Company’s financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continually evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual results could differ from these estimates.
i. | Significant Judgments in Applying Accounting Policies
The areas which require management to make significant judgments in applying the Company’s accounting policies in determining carrying values include, but are not limited to:
(a) | Mineral Reserves and Mineral Resources
The information relating to the geological data on the size, depth and shape of the ore body requires complex geological judgments to interpret the data. Changes in the proven and probable mineral reserves or measured and indicated and inferred mineral resources estimates may impact the carrying value of property, plant and equipment, reclamation and remediation obligations, recognition of deferred tax amounts and depreciation, depletion and amortization.
(b) | Depreciation, depletion and amortization
Significant judgment is involved in the determination of useful lives and residual values for the computation of depreciation, depletion and amortization and no assurance can be given that actual useful lives and residual values will not differ significantly from current assumptions.
(c) | Taxes
The Company is subject to income taxes in numerous jurisdictions. Significant judgment is required in determining the provision for income taxes, due to the complexity of legislation. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business.
ii. | Significant Accounting Estimates and Assumptions
The areas which require management to make significant estimates and assumptions in determining carrying values include, but are not limited to:
(a) | Determination of Mineral Reserves and Mineral Resources
Proven and probable mineral reserves are the economically mineable parts of the Company’s measured and indicated mineral resources demonstrated by at least a preliminary feasibility study. The Company estimates its proven and probable mineral reserves and measured and indicated and inferred mineral resources based on information compiled by appropriately qualified persons. The estimation of future cash flows related to proven and probable mineral reserves is based upon factors such as estimates of commodity prices, foreign exchange rates, future capital requirements and production costs along with geological assumptions and judgments made in estimating the size and grade of the ore body. Changes in the proven and probable mineral reserves or measured and indicated and inferred mineral resources estimates may impact the carrying value of property, plant and equipment, goodwill, reclamation and remediation obligations, recognition of deferred tax amounts and depreciation, depletion and amortization.
(b) | Depreciation, depletion and amortization
Plants and other facilities used directly in mining activities are depreciated using the UOP method over a period not to exceed the estimated life of the ore body based on recoverable ounces to be mined from proven and probable reserves. Mobile and other equipment is generally depreciated, net of residual value, on a straight-line basis, over the useful life of the equipment and generally does not exceed the related estimated life of the mine based on proven and probable reserves. The calculation of the UOP rate, and therefore the annual depreciation, depletion and amortization expense, could be materially affected by changes in the underlying estimates. Changes in estimates can be the result of actual future production differing from current forecasts of future production, expansion of mineral reserves through exploration activities, differences between estimated and actual costs of mining and differences in gold price used in the estimation of mineral reserves.
(c) | Valuation long-lived assets
The assessment of fair values for potential impairment and long-lived assets for potential impairment or reversal of impairment, require the use of estimates and assumptions for recoverable production, future capital requirements and operating performance, as contained in the Company’s LOM plans, as well as future and long-term commodity prices, discount rates and foreign exchange rates. Changes in any of the assumptions or estimates used in determining the fair value of other long-lived assets could impact the impairment analysis. The Company’s LOM plans are based on detailed research, analysis and modeling to maximize the NAV of each CGU. As such, these plans consider the optimal level of investment, overall production levels and sequence of extraction taking into account all relevant characteristics of the ore body, including waste to ore ratios, ore grades, haul distances, chemical and metallurgical properties impacting process recoveries, capacities of available extraction, haulage and processing equipment, and other factors. Therefore, the LOM plan is an appropriate basis for forecasting production output in each future year and the related production costs and capital expenditures. The LOM plans have been determined using cash flow projections from financial budgets approved by senior management. Projected future revenues reflect the forecast future production levels at each of the Company’s CGUs as detailed in the LOM plans. These forecasts may include the production of mineralized material that does not currently qualify for inclusion in mineral reserve or mineral resource classification. This is consistent with the methodology used to measure value beyond proven and probable reserves when allocating the purchase price of a business combination to acquired mining assets. The fair value arrived at, as described above, is the Company’s estimate of fair value for accounting purposes and is not a “preliminary assessment”, as defined in Canadian Securities Administrators’ National Instrument 43-101 “Standards of Disclosure for Mineral Projects”. Projected future revenues also reflect the Company’s estimates of future metals prices, which are determined based on current prices, forward prices and forecasts of future prices prepared by industry analysts. These estimates often differ from current price levels, but the methodology used is consistent with how a market participant would assess future metals prices. For the 2023 annual analysis, estimated 2024, 2025, 2026 and long - term gold prices of $1,900, $1,900, $1,800 and $1,700 per ounce, respectively, and short - term and long - term silver prices of $23 per ounce were used. For the 2022 annual analysis, estimated 2023, 2024, 2025 and long-term gold prices of $1,700, $1,700, $1,700 and $1,600 per ounce, respectively, and short-term and long-term silver prices of $21 per ounce were used. The Company’s estimates of future cash costs of production and capital expenditures are based on the LOM plans for each CGU. Costs incurred in currencies other than the U.S. dollar are translated to U.S. dollar equivalents based on long-term forecasts of foreign exchange rates, on a currency by currency basis, obtained from independent sources of economic data. Oil prices are a significant component of cash costs of production and are estimated based on the current price, forward prices, and forecasts of future prices from third party sources. For the 2023 annual analysis, estimated 2024, 2025, 2026 and long - term oil prices of $80, $70, $70 and $70 per barrel, respectively were used. For the 2022 annual analysis, estimated 2023, 2024, 2025 and long-term oil prices of $90, $70, $70 and $70 per barrel, respectively were used. The discount rate applied to present value the net future cash flows is based on a real weighted average cost of capital by country to account for geopolitical risk. For the 2023 annual analysis a discount rate of 5.10% (2022 – 5.20%) was used to test the Round Mountain CGU.
(d) | Inventories
Expenditures incurred, and depreciation, depletion and amortization of assets used in mining and processing activities are deferred and accumulated as the cost of ore in stockpiles, ore on leach pads, in-process and finished metal inventories. These deferred amounts are carried at the lower of average cost or NRV. Write-downs, and subsequent reversals thereof, of ore in stockpiles, ore on leach pads, in-process and finished metal inventories resulting from NRV impairments are reported as a component of current period costs. The primary factors that influence the need to record write-downs and related reversals include prevailing and long-term metal prices and prevailing costs for production inputs such as labour, fuel and energy, materials and supplies, as well as realized ore grades and actual production levels. Costs are attributed to the leach pads based on current mining costs, including applicable depreciation, depletion and amortization relating to mining operations incurred up to the point of placing the ore on the pad. Costs are removed from the leach pad based on the average cost per recoverable ounce of gold on the leach pad as the gold is recovered. Estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads, the grade of ore placed on the leach pads and an estimated percentage of recovery. Timing and ultimate actual recovery of gold contained on leach pads can vary significantly from the estimates. The quantities of recoverable gold placed on the leach pads are reconciled to the quantities of gold actually recovered (metallurgical balancing), by comparing the grades of ore placed on the leach pads to actual ounces recovered. The nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored and the engineering estimates are refined based on actual results as well as for changes to the mine plan over time. The ultimate actual recovery of gold from a pad will not be known until the leaching process is completed. The allocation of costs to ore in stockpiles, ore on leach pads and in-process inventories and the determination of NRV involve the use of estimates. There is a high degree of judgment in estimating future costs, future production levels, forecasted usage of supplies inventory, proven and probable reserves estimates, gold and silver prices, and the ultimate estimated recovery for ore on leach pads. There can be no assurance that actual results will not differ significantly from estimates used in the determination of the carrying value of inventories.
(e) | Provision for reclamation and remediation
The Company assesses its provision for reclamation and remediation on an annual basis or when new material information becomes available. Mining and exploration activities are subject to various laws and regulations governing the protection of the environment. In general, these laws and regulations are continually changing and the Company has made, and intends to make in the future, expenditures to comply with such laws and regulations. Accounting for reclamation and remediation obligations requires management to make estimates of the future costs the Company will incur to complete the reclamation and remediation work required to comply with existing laws and regulations at each mining operation. Actual costs incurred may differ from those amounts estimated. Also, future changes to environmental laws and regulations could increase the extent of reclamation and remediation work required to be performed by the Company. Increases in future costs could materially impact the amounts charged to operations for reclamation and remediation. The provision represents management’s best estimate of the present value of the future reclamation and remediation obligation. The actual future expenditures may differ from the amounts currently provided.
(f) | Deferred taxes
The Company recognizes the deferred tax benefit related to deferred income and resource tax assets to the extent recovery is probable. Assessing the recoverability of deferred income tax assets requires management to make estimates of future taxable profit. To the extent that future cash flows and taxable profit differ significantly from estimates, the ability of the Company to realize the net deferred tax assets recorded at the balance sheet date could be impacted. In addition, future changes in tax laws could limit the ability of the Company to obtain tax deductions in future periods from deferred income and resource tax assets.
(g) | Contingencies
Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. Contingencies can be possible assets or liabilities arising from past events which, by their nature, will only be resolved when one or more future events not wholly within our control occur or fail to occur. The assessment of such contingencies involves the use of significant judgment and estimates. In the event that management’s estimate of the future resolution of these matters changes, the Company will recognize the effects of the changes in its consolidated financial statements on the date such changes occur.
