Mexican miner and metals processor Industrias Penoles on Tuesday posted a more than 400% year-on-year jump in its second-quarter profit, helped by better metals prices, higher sales and far lower financial costs. The company, which runs the world’s largest primary silver producer, Fresnillo, made 3.22-billion pesos ($177.64-million) in profit during the three-month period, up from 639.3-million pesos in the same quarter of 2016.
