Notes to Editors:
About Rio Tinto’s Argyle Diamond Mine
Rio Tinto’s Argyle Diamond mine (100% owned by Rio Tinto), in Australia, is the
world’s only consistent supplier of rare pink diamonds and provides a large
proportion of the world’s champagne and cognac diamonds. Production commenced
in 1983 and includes small, coloured diamonds - on average produces 30 million
carats per annum.
The discovery of the Argyle diamond deposit is one of innovation, patience, foresight
and meticulous attention to detail in an area that is remote, even for Australians.
The search for diamonds in the Kimberley region began in 1972 with a number of
exciting finds proving uneconomic. However, in October 1979 diamonds were found
embedded in an ant hill in the East Kimberley region of Western Australia.
In a classic exploration exercise these discoveries were followed up along a creek
bed and led to what is known as the AK1 pipe, the remnant of an ancient volcano
and the site of the vast Argyle deposit. Today most of the valley floor is occupied by
the Argyle open pit.
Pink diamonds’ value is directly related to their rarity. For every coloured diamond,
there exists at least 10,000 colourless ones because the physical conditions needed
to colour a diamond naturally occur very scarcely.
It has long been a mystery and the subject of ongoing debate of how the pink
diamonds are formed. It is now generally accepted that the pink colour is derived
from a distortion in the molecular structure of the diamond, following formation in the
earth’s mantle or during their ascent to the earth’s surface. This process is referred
to as plastic deformation and the degree of the distortion in the structure impacts on
the way it reflects light and the resulting colour.
Rio Tinto’s Argyle mine occupies the traditional land of the Gidja and Mirriuwong
speaking people and neighbouring language groups who have a very different view on
how the Argyle diamonds became coloured. The Aboriginal people believe that the
Argyle mine was created when three women were trying to trap a barramundi fish,
however the barramundi was too clever and jumped through the net and landed at the
site where the mine was established. It’s believed that the colours of the diamonds
come from different parts of the barramundi as the fish wiggled through the net, with
the pink diamonds coming from the heart of the barramundi.
