Freeport-McMoRan announced plans to build a copper smelter and develop its gold and copper mines in East Java, Indonesia, with an investment of around $17bn.
The company is said to have signed a preliminary agreement with PT Petrokimia Gresik to build the smelter, according to the Wall Street Journal.
Freeport-McMoRan president director Maroef Sjamsuddin was reported by Bloomberg as saying the smelter will cost more than $2bn and a further $15bn will be spent on the long-term development of underground copper and gold deposits at its Grasberg mine complex in Papua.
Freeport's latest decision comes after the announcement made by Indonesia Energy and Mineral Resources Minister Sudirman in January last year, saying that the government would ban the company's local unit from shipping copper concentrate outside of the country.
Kansanshi Mines stated that it would not invest $1.5bn in the ongoing expansion of its facility in Solwezi unless the Zambian Government provided a tax refund.
Kansanshi Mines was quoted by Zambia Reports as saying that, as the company is yet to receive $230bn in tax refunds, it will not be able to investment in new projects until it receives the money.

US Mine Safety and Health Administration (MSHA) released the final rule for underground coal mines to reduce potential pinning, crushing, or striking incidents.
As per the new guidance, underground coal mining operators must install proximity detection systems on place-changing continuous mining machines.
The detection system will use electronic sensors to help both mining machines and miners detect motion or the location of one object relative to another, to prevent accidents.
The sensors can be programmed to form a perimeter around a continuous mining machine and a receiver worn by the machine operator interacts with the sensors installed at the machine's corners.
Chilean environmental regulator Superintendence for the Environment (SMA) is re-evaluating penalties on Barrick Gold's Pascua-Lama project located on the border of Chile and Argentina in the Frontera district.
Reuters cited SMA head Cristian Franz in an interview published in Diario Financiero as saying that: "The new sanction can fall anywhere on the spectrum allowed by the law, which goes from a warning to revoking the environmental permit, including fines."
In May 2013, SMA fined the Canadian mining company $16m for not complying with some of the country's environmental requirements at Pascua-Lama gold and silver project.
During that time, the Supreme Court refused to hear Barrick's appeal when the country's Environment Court found the fines were not well determined.

Severny Kuzbass is said to operate two coal mines in Siberia, the Federal Anti-Monopoly Service reported.

As part of the transaction, ArcelorMittal will sell assets such as the coal mines of Berezovskaya and Pervomaskaya, which jointly produce 700,000t of coal a year.
Arrium announced plans to close its iron ore mining operation in South Australia, resulting in the loss of almost 600 jobs.
The company's latest decision aimed to increase cash generation and deliver for sale around nine million tonnes a year (Mtpa) of iron ore for sale.
Arrium's re-design plan follows the substantial decline in iron ore prices over the last half year, as well as growing uncertainty around the timing of a price recovery.
Iron ore prices are said to be at five-year low and down 45% compared with previous years. This has pushed Arrium into a position where it is absorbing cash despite significant achievements in reducing costs and capital expenditure, the company said.
