In the first half of 2019, Silvertip recognized a $27.3 million write-down of metal inventory as a result of lower than expected production levels, grades and recovery rates as well as reduced process plant availability. It is possible that additional write-downs will be required as the Company works to optimize operations at Silvertip.
