Significant Accounting Judgments and Estimates [Abstract] |
Significant Accounting Judgments and Estimates | 4.Significant Accounting Judgments and Estimates 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, liabilities and contingent liabilities at the date of the financial statements and reported amounts of income and expenses during the reporting period. Estimates and assumptions are continuously 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. However, actual outcomes may differ significantly from these estimates. Judgments and estimates that have the most significant effect on the amounts recognized in the Company’s consolidated financial statements are as follows:
| ● | Exploration and Evaluation Assets
The net carrying value of each mineral property is reviewed regularly for conditions that suggest potential indications of impairment. This review requires significant judgment. Factors considered in the assessment of asset impairment include, but are not limited to, whether there has been a significant adverse change in the legal, regulatory, accessibility, title, environmental or political factors that could affect the property’s value; whether exploration activities produced results that are not promising such that no more work is being planned in the foreseeable future and management’s assessment of likely proceeds from the disposition of the property.
| ● | Financial Derivative Liability
The Financial Derivative Liability values relating to convertible note and US dollar denominated warrants involve significant estimation. The fair value of financial derivative liability was determined at inception and is reviewed and adjusted on a quarterly basis or when conversions take place. Factors considered in the fair value of the financial derivative liability are risk free rate, the Company’s share price, equity volatility, and credit spread, refer to Note 22.
| ● | Environmental Rehabilitation
Management’s determination of the Company’s decommissioning and rehabilitation provision is based on the reclamation and closure activities it anticipates as being required, the additional contingent mitigation measures it identifies as potentially being required and its assessment of the likelihood of such contingent measures being required, and its estimate of the probable costs and timing of such activities and measures. Significant estimations must be made when determining such reclamation and closure activities and measures required and potentially required.
| ● | Refinery Asset
The net carrying value of the Refinery asset is reviewed regularly for conditions that suggest potential indications of impairment. The review requires significant judgment. Factors considered in the assessment of asset impairment include, but are not limited to, whether there has been a significant adverse change in the technological, market, economic or legal environment in which the entity operates; and internal indicators that the economic performance of the asset will be worse than expected.
