Antofagasta posts higher Q1 output, 2017 guidance unchanged
LONDON, April 26 (Reuters) - Chilean copper producer Antofagasta (Other OTC: ANFGF - news) said on Wednesday copper production for the first quarter rose 9 percent on an improved performance at two of its mines and it kept its output target for the year unchanged.
Copper production for the miner reached 171,900 tonnes, a 9.4 percent increase to a year ago but fell 16.4 percent compared to the previous quarter due to lower grades.
Antofagasta stuck to its 2017 output target at 685,000-720,000 tonnes. (Reporting by Zandi Shabalala, editing by Louise Heavens)
