Rio Tinto today officially opened its Silvergrass iron ore mine in Western Australia. The $338 million project is the 16th mine at Rio Tinto’s world-class iron ore operations and will produce low-phosphorous ore crucial to maintaining Rio Tinto’s premium Pilbara Blend product.
Rio Tinto chief executive J-S Jacques said “Silvergrass is a great example of our value-over-volume approach in action as the mine will deliver the high-quality, low-cost ore used to maintain the world-class premium Pilbara Blend product our customers love so much. Silvergrass is a further demonstration of our long-standing commitment to the Pilbara region in Western Australia where we’ve invested more than $20 billion over the past decade.”
West Australian Premier Mark McGowan today led the formalities at a ceremony in the Pilbara to mark the opening, with full commissioning scheduled before the end of the year.
The brownfields expansion project will lower mine operating costs as a result of the construction of a 9-km conveyor system that will replace traditional road haulage routes linking Silvergrass to the existing processing plant at Nammuldi.
More than 500 jobs as well as opportunities for indigenous contracting were created during the construction of the mine. Contracts worth more than A$180 million were awarded during the construction phase, including contracts to Western Australian company Decmil and Perth headquartered company RCR Resources.
Rio Tinto Iron Ore chief executive Chris Salisbury said “Silvergrass is another Rio Tinto project delivering value for Western Australia with design, construction and commissioning all undertaken by WA companies. Dozens of local businesses have benefitted from the purchase of major items including modular buildings, gantry cranes and a waste water treatment plant.”
The Premier also attended celebrations in Perth last night to mark the 30-year anniversary of Rio Tinto and Sinosteel Corp’s historic Channar Mining Joint Venture.
Rio Tinto hosted Sinosteel President Liu Andong and former Australian Prime Minister Bob Hawke, who was present at the original signing ceremony in 1987.
Salisbury said “The strong partnership we have forged with Sinosteel over the past 30 years is one of Australia’s most significant trading relationships. It has seen Rio Tinto deliver more than 250 Mt of iron ore to China, undoubtedly helping transform the Chinese economy.”
- Rio Tinto shipped its five billionth tonne of iron ore last year after 50 years of operations in the Pilbara

- Silvergrass is a satellite deposit located adjacent to Rio Tinto’s Nammuldi mine and is part of the Greater Nammuldi precinct, located approximately 70 km northwest of Tom Price
- Ore from the Silvergrass mining operations is high-quality, low-phosphorus Marra Mamba ore that is treated at the Greater Nammuldi processing plant and blended into Rio Tinto’s premium Pilbara Blend product
- Silvergrass is a wholly-owned operation conducted under the Iron Ore (Hamersley Range) Agreement Act 1963
- The mine will add 10 Mt of annual production capacity.
- The Channar JV was the first large-scale mining initiative between China and Australia, and formed the basis of many agreements and investments to follow in mining and liquid natural gas sectors
- The joint venture is 60% owned by Rio Tinto (through Hamersley Iron) and 40% by Sinosteel
- In November 1987, at a ceremony with the then Australian Prime Minister Bob Hawke, Rio Tinto and Sinosteel agreed on a 200 Mt supply agreement over a 20-year period. This was later extended by 50 Mt in 2010
- In April 2016 in Beijing at a ceremony with Australian Prime Minister Malcolm Turnbull and Chinese Premier Li Keqiang, Rio Tinto and Sinosteel agreed to extend the agreement for a second time. This current extension will see 30 Mt of iron ore supplied into the joint venture. In addition Rio Tinto will sell up to 40 Mt to Sinosteel through to 2021
