The income and mining tax benefit (provision) for the three and nine months ended September 30, 2021 and 2020 varies from the amounts that would have resulted from applying the statutory tax rates to pre-tax income due primarily to the impact of taxation in foreign jurisdictions and reversal of the valuation allowance portion related to net operating loss utilization. The valuation allowance reversed for utilization of net operating loss carryforward for the three and nine months ended September 30, 2021 totaled $1.1 million and $9.7 million, respectively.
