The Manitoba government realized $8.3 million in revenue from mining taxes in 2013-14, almost $30 million below its projections, reports the Winnipeg Free Press.
The province blamed feeble metal prices, but the opposition Progressive Conservatives accused the NDP of questionable forecasting, according to the newspaper.
Deputy finance minister Jim Hrichishen told the Free Press that any discrepancy in revenue is a concern but added that overall, Manitoba has a good record when it comes to predicting resource revenue.
The newspaper notes that mining tax revenue over the past five years has been as high as $61.4 million (2011-12).
The bulk of mining in Manitoba takes place in Thompson, Flin Flon and Snow Lake.
