On March 31, 2016, Coeur sold its 2.0% NSR royalty on the Cerro Bayo mine to the operator, a subsidiary of Mandalay Resources Corporation ("Mandalay"), for total consideration of approximately $5.7 million, consisting of $4.0 million in cash and 2.5 million Mandalay shares. The mineral interest associated with the Cerro Bayo mine was included in the Coeur Capital segment.

The operator of the Endeavor mine in Australia, on which the Company has a 100% silver stream, recently announced a significant curtailment of production due to low lead and zinc prices. As a result, Coeur recorded a $2.5 million write-down of the mineral interest associated with the Endeavor silver stream within the Coeur Capital segment.

On April 19, 2016, Coeur sold its tiered NSR royalty on the El Gallo mine to the operator, a subsidiary of McEwen Mining Inc., for total consideration of approximately $6.3 million, including $1 million in contingent consideration payable in mid-2018. In anticipation of this sale, the Company recorded a $1.9 million write-down of the mineral interest within the Coeur Capital segment at March 31, 2016.
