The Chilean Copper Commission (COCHILCO) said that the country will delay work on 11 mining projects because of increasing operational costs.
The seven copper and four gold projects, valued at $38.9bn, were proposed as part of the Chile’s total portfolio of 45 mining projects in 2012, valued at $104.3bn.
Difficulties in upgrading the processes for environmental impact assessment and permit approvals for project infrastructure construction were believed to have contributed to the delay.
Canada-based mining and metals company First Quantum Minerals has accused INMET Mining of attempting to sabotage its C$5.1bn ($5.17bn) takeover bid, by proposing to sell a stake in the Cobre Panama project.

CEO Philip Pascall noted that it is a condition of First Quantum’s offer that Inmet and its subsidiaries do not take any action that could reduce the value of the offer to Inmet.
Towards the end of the month, First Quantum Minerals vowed to host a series of investor meetings to pitch its hostile takeover bid directly to Inmet shareholders.

Unregulated coal mining has led to a series of cave-ins, creating more than 20 crater-like pits in Fukou, a county in the Hunan Province of China.

Meanwhile, The Australian Government has refused to reveal mining tax earnings paid by individual mining companies and said that doing so would break the law.
