(1)On September 16, 2020, the Company acquired Alacer, including Çöpler (notes 1(a) and 4(a)). The consideration included the assumption of non-current environmental and reclamation obligations valued at $26.2 million.

(2)On June 27, 2019, the Company acquired 8,900 hectares of land contiguous to Marigold in Nevada, U.S., net of a 0.5% net smelter returns royalty. The consideration included $22.0 million in cash and the assumption of related non-current environmental and reclamation obligations then valued at approximately $13.0 million.

The reclamation and closure cost provision is calculated as the present value of estimated future net cash outflows based on the following key assumptions:

▪Discount rates used in discounting the estimated reclamation and closure cost provision range between 0.7% and 12.1% for the year ended December 31, 2020 (2019 - 1.8% and 9.9%).

▪The majority of the expenditures are expected to occur between 2027 and 2045.

▪A 1% change in the discount rate would increase or decrease the provision on a consolidated basis by approximately $18.1 million (2019 - $11.1 million), while holding other assumptions consistent.
