Risks

• Ability to achieve production at Donlin Gold.
• Cost estimates and assumptions contained in the 2021 Technical Report and S-K 1300 Technical Report Summary may prove to be significantly incorrect.
• Ability to develop adequate infrastructure and the reasonableness of associated costs.
• Obtaining necessary permits and governmental approvals and the timing of such approvals.
• Uncertainties involved in the interpretation of drill results and geological tests, and the estimation of reserves and resources.
• Demand for equipment, skilled labor, and services needed for exploration and development of mineral properties.
• Adverse disruption or impediment by development, operating, or regulatory risks.
• Need for additional financing to complete an updated feasibility study and to explore and develop properties.
• Availability of financing in the debt and capital markets.
• Disease pandemics affecting operations.
• Changes in mineral production performance, exploitation, and exploration successes.
• Changes in national and local government legislation, taxation, controls or regulations, and/or changes in the administration of laws, policies and practices.
• Expropriation or nationalization of property and political or economic developments in the United States or Canada.
• Need for continued cooperation between the owners of Donlin Gold LLC to advance the project.
• Need for cooperation of government agencies and Native groups in the development and operation of properties.
• Risks of construction and mining projects such as accidents, equipment breakdowns, bad weather, non-compliance with environmental and permit requirements, unanticipated variation in geological structures, ore grades or recovery rates.
• Unexpected cost increases, which could include significant increases in estimated capital and operating costs.
• Fluctuations in metal prices and currency exchange rates.
• Uncertainty regarding whether or when a positive construction decision will be made for the Donlin Gold project.

Future Outlook
