Owner Ramu Nico Management (MCC) Limited

Ramu-Nickel-Logo.jpg (4423 bytes)

Location Madang Province
Papua New Guinea
Background The Project is an unincorporated joint venture between MCC Ramu (85%); MRML (2.5%) and MRRL (with 3.94%) two subsidiaries of Mineral Resource Development Corporation (MRDC) on behalf of PNG government and landowner interests; and RNL (8.56%), a subsidiary of former developer Highland Pacific Ltd.  Ramu NiCo Management (MCC) Limited, as the Manager of the Project appointed by all joint venture parties, is fully responsible for construction, development and operation of the Project.
In China, MCC Ramu NiCo Limited is wholly owned by MCC-JJJ Mining, whose shareholders include China Metallurgical Group Corporation (MCC), a Fortune 500 company and three of the largest enterprises in the Chinese nickel and stainless steel industry, namely Jinchuan Group Limited, Jilin Jien Nickel Industry Limited, and Jiuquan Iron & Steel (Group) Limited. These four giants give the Project strong supports on financing, technology and operation, and furthermore form a strategic alliance in developing and consuming nickel and cobalt.

General Located in Madang Province on the north coast of Papua New Guinea, Ramu is a large “wet tropical” laterite nickel and cobalt project, whose mine life is predicted at 35 to 40 years. It will potentially yield about 33,000 tonnes of nickel and 3,300 tonnes of cobalt contained in a high-grade intermediate product.

The Project is composed of three parts: the Kurumbukari mine site, the Basamuk processing plant and a 135 kilometers slurry pipeline from the mine to the processing plant. The mine is located on the Kurumbukari plateau, on the southern side of the Ramu River Valley, 75 kilometers to the southwest of Madang. The processing plant site is located on coast of Basamuk bay, 55km to the southeast of Madang.

News July 2012 - Highland Pacific says that comissioning continues at the Ramu nickel-cobalt project in Papua New Guinea.  According to the company, ore treatement began in one of the three high-pressure autoclaves in early March and had by May operated continuously for six weeks with no major processing issues, during which time 300,000 tonnes of slurried ore was treated, producing 486 tonnes of mixed nickel-cobalt hydroxide.  The first autoclave was to be closed down at the end of April for inspection, and the second autoclave circuit started for similar testing.  At full production, Ramu will consume 360,000 t/a sulphur to produce 1.1 million t/a of sulphuric acid which will be used to leach 31,150 t/a of nickel and 3,300 t/a cobalt as mixed hydroxide.

 

December 17, 2010 - Reuters reported that Papua New Guinea's Ramu Nickel Mine, majority owned by China's Ramu Nico Management, will commence production in 2011 working up to an annualized rate of 31,150 tonnes of nickel and 3,300 tonnes of cobalt.  Mr Wu Xeng, a company official, said that "We are 95% complete, and nearing production."

 

October 25, 2010 - The Chinese developer of Papua New Guinea's Ramu Nickel mine has been allowed to resume work on the construction of a deep sea tailings disposal pipeline.  China's Ramu Nico will now go ahead with the construction of the proposed pipeline from the Kurumbukari mine site to Madang's Basamuk Bay.  It plans to dump millions of tonnes of slurry waste from the mine via the pipeline into the seas north of Madang.  Affected landowners have successfully stopped the construction of the pipeline, but later withdrew the case under controversial circumstances.  Another landowner Loius Medaing has filed fresh proceedings to stop the deep sea tailings.  Late last week, PNG's National Court in Madang refused another injunction and instead allowed the construction work to resume.  But the court has also ordered the developer not to dump any wastes via the pipeline, until the case is determined early next month. Both parties have been advised to prepare for a full trial in the New Year.  PNG's Ramu nickel mine was reportedly scheduled to commence trial operation later this year.

 

August 25, 2010 - Production at Metallurgical Corp of China Ltd's (MCC) Ramu nickel mine in Papua New Guinea is likely to be delayed to the end of the year, six months later than previously scheduled, a senior executive said on Wednesday.  "We estimate the Ramu nickel mine will be able to start production by the end of this year," MCC Vice-President Huang Dan told a news conference in Hong Kong.  Construction of the mine has been delayed due to health-related safety checks, she said.  Once it starts production, the mine is expected to produce 40,000 tonnes of metal in the first year, 78,000 tonnes in the second year, 77,000 tonnes in the third year and 74,000 tonnes in the fourth year.

 

May 11, 2009 - Construction of a $1.7 billion nickel project in Papua New Guinea has been halted due to fighting between local workers and Chinese labour, local media reported on Monday.   The fighting last Friday resulted in injuries to 14 Chinese and three local workers, as well as extensive property and equipment damage, said The Post Courier newspaper in the capital, Port Moresby.  Mine management told the newspaper that construction had halted at the site.  "We call on the PNG Government and police to fully investigate the incident and bring the perpetrators to justice, and to promptly restore law and order on site," the mine management in a statement in the newspaper.   Construction of the Ramu mine has been plagued by disputes with local landholders, many of whom also work at the site. Majority-owner China Metallurgical Construction Group Corp (MCC) has accused officials of forcing locals to work in sub-standard conditions.   Last August, local workers attacked Chinese labour and shut the gates to the project over working conditions.  The Post Courier newspaper said the latest fighting was over rumours of an accident at the site involving a Papua New Guinea worker.   Police reinforcements have been sent to the mine site near Madang on the north coast to investigate the fighting and to provide security to Chinese workers, said The National newspaper.

July 23, 2008 - Papua New Guinea's Chinese-backed Ramu nickel and cobalt project has secured nearly one-point-four billion US dollars in funding - the final hurdle before the project can become operational. The announcement was made by the junior joint-venture partner, Highlands Pacific, to the Australian Stock Exchange today. The China Metalurgical and Construction Company, or MCC, is the largest of the four Chinese joint-venture partners.

April 1, 2008 - Australia-based Highlands Pacific Ltd and its joint venture partner, MCC Ramu NiCo Ltd will start large-scale construction at the Ramu Nickel Project in Papua New Guinea within 3 months. About USD 200 million has already been committed or spent on the USD 1.37 billion project, the financing for which will be finalized within the next three months subject to approval from the Chinese government. The Ramu Nickel project is part owned by a Chinese syndicate. About 40% of the project cost will be financed by Chinese banking institutions, 30% will come via a shareholder loan from the Chinese syndicate and the rest as shareholder equity. This means the project is being financed by 30% equity and 70% debt, which is to be repaid over 10 years. The Chinese syndicate comprising MCC-JJJ Mining Development Co. owns 100% of MCC Ramu NiCo Ltd, which in turn holds 85% of the Ramu project. Highlands has an 8.56% interest in the Ramu project, which will increase to 11.30% at no cost to the company after repayment of its part of the debt.
