[1] | For the year ended December 31, 2017 and comparative periods, Peak Mines has been classified as a discontinued operation and accordingly earnings and cash flows from continuing operations are presented exclusive of Peak Mines. Refer to Note 16 for further details.
[2] | For the periods in which the Company records a loss, diluted loss per share is calculated using the basic weighted average number of shares outstanding, as using the diluted weighted average number of shares outstanding in the calculation would be anti-dilutive.
