安托法加斯塔矿业与智利森蒂纳铜矿两个罢工工会的谈判周四毫无进展，而三名工人已进入第七天绝食。
Negotiations between Antofagasta Minerals and two striking unions at Chile's Centinela copper mine showed no progress on Thursday, while three workers marked their seventh day on a hunger strike.
代表超过700名工人的森蒂纳区和埃斯佩兰萨矿业工会因合同谈判破裂于10月7日发起罢工。双方周二重返谈判桌，试图解决争端。
The Distrito Centinela and Minera Esperanza unions, which together represent more than 700 workers, began the walkout on October 7 after contract talks collapsed. The sides returned to the negotiating table on Tuesday in an effort to resolve the dispute.
工会在声明中表示：“迄今为止，经过三天的自愿调解，公司拒绝讨论在集体协议期限内终止歧视的机制。”
"So far, after three days of voluntary mediation, the company has refused to address a mechanism to end discrimination during the term of the collective agreement," the unions said in a statement.
工会补充称，公司继续提出工人已拒绝的财务方案，而忽视他们所说的核心问题：所谓工人基本权利——平等待遇和非歧视权的违反。
The unions added that the company was continuing to present a financial offer already rejected by workers, while ignoring what they called the core issue: alleged violations of workers' fundamental rights to equal treatment and non-discrimination.
工会称，争议焦点在于矿山中从事类似工作的工人在薪酬和福利上的所谓差异。
The unions say the dispute centers on alleged disparities in pay and benefits for workers performing similar roles at the mine.
安托法加斯塔周三表示，迄今为止已按计划维持生产运行。周四，公司报告称第三季度产量增长7%，并维持全年产量预测为62.5万至65.5万吨铜。
Antofagasta said on Wednesday that it had so far managed to keep production running as planned. On Thursday, the company reported a 7% rise in third-quarter output and maintained its full-year production forecast of 625,000 to 655,000 metric tons of copper.
公司周四在声明中重申其寻求协议的意愿，并称本周的对话已为达成协议打开可能性。公司表示反对使用可能危及工人健康和生命的绝食罢工。
In a statement on Thursday, the firm reaffirmed its willingness to seek an agreement, and said dialogue this week has opened up the possibility to reach a deal. The company said it opposed the use of a hunger strike that could put workers' health and lives at risk.
森蒂纳的罢工——以及最终被避免的埃斯康迪达主管停工风险——在全球供应扩张不足以满足未来需求的担忧中，有助于支撑全球铜价。
The strike at Centinela — along with the ultimately averted risk of a supervisors' stoppage at Escondida — has helped support global copper prices, amid concerns of difficulties to expand supply enough to meet expected future demand.
