In 2022, the Company entered into a Facilities Agreement with BC Hydro covering the design and construction of facilities by BC Hydro to supply construction phase hydro-sourced electricity to the KSM project. The cost to complete the construction is estimated to be $32.8 million of which the Company has paid $11.7 million to BC Hydro and the remaining balance is due in 2023. In addition, the Facilities Agreement requires $54.2 million in security or cash from the Company for BC Hydro system reinforcement which is required to make the power available of which the Company has paid $21.2 million to BC Hydro and the balance is due in 2023. The $54.2 million system reinforcement security will be forgiven annually, typically over a period of less than 8 years, based on project power consumption. Subsequent to December 31, 2022, $43.7 million was paid to BC Hydro. Prior to its maturity, the secured note bears interest at 6.5%, or US$14.6 million per annum, payable quarterly in arrears. The Company can elect to satisfy interest payments in cash or by delivering common shares. Refer to Note 12 for details on the secured note. As previously disclosed in the Company’s prior years financial statements, in 2019 the Company received a notice from the CRA that it proposed to reduce the amount of expenditures reported as Canadian Exploration Expenses (CEE) for the three-year period ended December 31, 2016. The Company has funded certain of its exploration expenditures, from time-to-time, with the proceeds from the issuance of flow-through shares and renounced, to subscribers, the expenditures which it determined to be CEE. The notice disputes the eligibility of certain types of expenditures previously audited and approved as CEE by the CRA. The Company strongly disagrees with the notice and responded to the CRA auditors with additional information for their consideration. In 2020, the CRA auditors responded to the Company’s submission and, although accepting additional expenditures as CEE, reiterated that their position remains largely unchanged and subsequently issued reassessments to the Company reflecting the additional CEE expenditures accepted and $2.3 million of Part Xll.6 tax owing. The Company has been made aware that the CRA has reassessed certain investors who subscribed for the flow-through shares, reducing CEE deductions. Notice of objections to the Company’s and investors’ reassessments have been filed for all those that have been received and will be appealed to the courts, should the notice of objections be denied. The Company has indemnified the investors that subscribed for the flow-through shares. The potential tax indemnification to the investors is estimated to be $10.8 million, plus $2.9 million potential interest. No provision has been recorded related to the tax, potential interest, nor the potential indemnity as the Company and its advisors do not consider it probable that there will ultimately be an amount payable. During 2021 and 2022, the Company deposited $9.3 million into the accounts of certain investors with the Receiver General, in return for their agreement to object to their respective assessments and agreement to repay the Company the full amount deposited on their behalf upon resolution of the Company’s appeal. The deposits made has been recorded as long-term receivables on the statement of financial position as at December 31, 2022.
