TOKYO, Aug 3 (Reuters) - Japan's Mitsui & Co Ltd said the Caserones copper mine in Chile was currently running at around 80 percent utilisation, a company executive said on Wednesday.
That's the same level that Caserones was running at in March, Mitsui's partner in the mine JX Holdings Inc said in May. JX also said at the time that it aims to reach near full utilisation at Caserones by the end of September.
Output at Caserones has been behind schedule since it started producing in May 2014. The mine booked a 28 billion yen ($277 million) loss for the year ending in March and may post a 17 billion yen loss for this financial year, JX said in May.
