(Adds sales volumes, analyst estimate)
April 24 (Reuters) - Canada's Teck Resources Ltd , the world's second-biggest exporter of steelmaking coal, reported on Tuesday higher-than-expected adjusted first-quarter earnings as sales volumes climbed.
Steelmaking coal sales volume rose to 6.1 million tonnes in the quarter ended March 31 from 5.7 million tonnes in the year-earlier quarter. Average quarterly realized price per tonne, however, fell to $207 from $212 a year earlier.
The sales volume was roughly in line with 6 million tonnes Teck forecast in March 9 after logistic issues and poor performance at a coal terminal in British Columbia prompted the company to cut the forecast.
Copper sales volumes rose 20 percent from a year earlier, said the company, which also mines zinc and gold.
Adjusted profit attributable to shareholders rose 15 percent to C$753 million ($586.4 million) or C$1.31 per share in the first quarter.
Analysts on average were expecting adjusted earnings of C$1.26 per share, according to Thomson Reuters I/B/E/S. ($1 = 1.2841 Canadian dollars) (Reporting by Nicole Mordant in Vancouver and Shalini Nagarajan in Bengaluru; Editing by Amrutha Gayathri)
