In 2018, Silvertip recognized a $26.7 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 and unfavorable changes in metal prices. It is possible that additional write-downs will be required as the Company works to optimize operations at Silvertip.
