The Canadian mining sector continued to face challenges in the final quarter of 2018, as a Chinese economic slowdown weighed on commodity prices, but advisory firm EY says there is reason to be optimistic for 2019. The EY Canadian Mining Eye index, which tracks the Canadian mining sector performance of 100 TSX- and TSX-V-listed midtier and junior companies with market capitalisations falling between C$158-million and C$2.2-billion, fell by 2% in the fourth quarter, following a 12% decrease in the third quarter.
