In November 2010, the Company received a reassessment from the Mexican tax authorities related to its Mexican subsidiary, Minera Cosalá, for the year ended December 31, 2007. The tax authorities disallowed the deduction of transactions with certain suppliers for an amount of approximately $9.6 million (MXN 196.8 million), of which $4.1 million (MXN 84.4 million) would be applied against available tax losses. The Company appealed this reassessment and the Mexican tax authorities subsequently reversed $4.6 million (MXN 94.6 million) of their original reassessment. The remaining $5.0 million (MXN 102.2 million) consists of $4.1 million (MXN 84.4 million) related to transactions with certain suppliers and $0.9 million (MXN 17.8 million) of value added taxes thereon.

The Company accrued $1.0 million (MXN 19.9 million) in the consolidated financial statements as at December 31, 2018 as a probable obligation for the disallowance of value added taxes related to the Mexican tax reassessment. As at December 31, 2021, the accrued liability of the probable obligation was $1.0 million (2020: $1.0 million). In July 2021, the Company has been served with a statement of claim that was filed in the Ontario Superior Court of Justice to commence a proposed class action lawsuit against the Company and its Chief Executive Officer (the “Action”). Pursuant to the Action, the representative plaintiff seeks damages of $130 million CAD in relation to the Company’s public disclosure concerning its Relief Canyon Mine. Although no assurance can be given with respect to the ultimate outcome, the Company believes that the complaint against it is unfounded and without merit, and it intends to vigorously defend the proceeding.
