July 26 (Reuters) - Canada's Teck Resources Ltd TCKb.TO TCK.N , the world's second-biggest exporter of steelmaking coal, reported a 12.6 percent increase in second-quarter adjusted earnings on Wednesday as higher metal prices more than offset lower sales volumes.
Teck, which also mines copper, zinc and bitumen, said adjusted profit rose to C$653 million ($500.8 million), or C$1.12 per share, in the three months to end June, from C$580 million, or 99 Canadian cents a share, in the same year-ago period. ($1 = 1.3038 Canadian dollars)
