Chile's senate approved on Wednesday a long-awaited new mining royalty bill, passing it back to the lower chamber for a final vote that could come as early as next week.
Chile is the world's top copper producer and the bill aims to raise taxes on large copper producers.
Earlier this week, the government said it reached an agreement with senators to cut the top tax rate to 46.5% from 47% for companies that produce over 80,000 tonnes of fine copper a year, and 45.5% for production in the 50,000-80,000 range.
