About the Argyle Diamond Mine

About the Argyle Diamond Mine -

If you think a diamond mine that produces around 20 million carats worth of diamond each year would be considered as among the largest mines in the world, you’re right. And that rightly describes Rio Tinto’s Argyle Diamond Mine operating in the region of East Kimberley, Western Australia since 1983. 

Having produced more than 800 million carats, it is among the largest diamond suppliers in the world, especially in terms of diamonds tinted in nature. The history of the Argyle Diamond Mine started with the diamond search in the small and remote areas of Western Australia as early as the 1970s. 

The Argyle Diamond Mine Tale

Without a doubt, it was a bold task, but it brought plenty of wonders and fully changed the understanding of the geological records! So, how did it all start?  In the 1940s, Ewen Tyler, then a University of Western Australia geology student, learned that kimberlite was the only standard host rock for diamonds.

This led to his fascination with the comments of Rex T. Prider, his geology lecturer, that the lamproite, an ultrapotassic mantle-derivative volcanic rock, found in the Kimberley area of Western Australia showed a strong match to those diamond rich rocks in South Africa.  

In 1979, diamonds were revealed after a dozen years of search by various firms in the region. 

The diamond deposit at Argyle was mined through open pit quarrying for the next 30 years. In the final month of 1985, open pit drilling commenced. At that time, the diamonds mined were of very low value, but the volumes remained immense.   

That marked the birth of Argyle as among the largest creators of diamonds in the world and the main supplier of naturally tinted diamonds, counting blue, cognac, white, champagne, and the extremely sought-after extraordinary pink diamonds.

The Argyle Diamond Mining, Processing, and Products 

Argyle is managed by the joint venture, Argyle Diamond Mines, which has been wholly owned by Rio Tinto since 2002. In 2012, the underground workshop and roadway construction was finished and the underground implements and dewatering drains were put in.

The underground pit began in April 2013, which paved the way to a new age of underground digging on the AK1 pit. Needless to say, the Argyle mine below the ground is pushing boundaries both in complexity and size, there are currently about 40 kilometres of tunnels.

The main roads in the network underground are four shafts, where two carry means of transportation, one for ore transfer, and the last for ventilation. At hand are two huge crushers underground, as well as conveyor belts transporting the minerals from deep within the mine towards the exterior. 

The Argyle processing plant is among the well-organised in the globe, processes a maximum of 11 million tons of ore each year. And that comes as no surprise because the Argyle processing plant and mine operate 24/7. Recently, there has been an especially large volume of pink diamonds.

Throughout history pink stones have smashed auction prices. And this demonstrates the distinct advantage of the Argyle Mine in producing remarkable jewels. Putting things into perspective, Argyle Diamond Mine is responsible for more than 90% of the best red and pink diamonds in the world today.

Still, less than one percent of the Argyle Mine diamonds are classified as this colour. This makes the pink diamonds of Argyle really rare since they do not exceed 4,000-carats per year. By themselves, though, pink diamonds often command auction prices far over and above those of clear diamonds, even those quite a bit larger. 

Even though the Argyle pit is typically linked to pink diamonds, it is likewise a major provider of brown stones, especially the irrefutably stylish Champagne diamonds. And take note that these champagne diamonds are increasing in popularity recently. A whopping 80% of the diamonds unearthed at the Argyle mine are brown.

Argyle Diamond Sales and Investment

The bulk of the Argyle diamonds are traded as uncut or rough diamonds. These are sorted and made ready for worldwide selling by the sales and marketing team of Rio Tinto in Antwerp, Belgium. All of the diamonds from Argyle are used in jewellery and find a home in all major global consumer markets. 

The average growth of investment for pink diamonds from Argyle is roughly 15% to 20% or more in some instances. 

The mainstream of the Argyle uncut diamonds are firms based in India. Also, the cutting trade of India is a key display place for growing the market in support of the small, tinted diamonds that sets apart the Argyle products. 

The Argyle Diamond Mine Social and Economic Responsibility

The Argyle diamond mine operates within an area of major social and economic disadvantage, and for this reason is committed to helping construct a strong community that is not solely reliant on the mining industry.   

To succeed in this, Argyle maintains good relations with civic and trade groups all over the eastern region of Kimberley. The projects and activities that Argyle funds are designed towards making the life of the people better. 

Examples include making towns top places to live in, fostering public leadership, keeping up local cultural events, and increasing up the supply of public health and education. In fact, as early as 2005, the signing of the Indigenous Land Use Agreement and Participation Agreement with the traditional owners and Argyle of the extracting lease area founded a rapport between the parties. 

The Argyle lease uses the territory of the Mirriuwung and Gidja people. As a result of the agreement, Argyle is helping in giving long-term economic assistance to the indigenous people of East Kimberley and, at the same time, protecting their environmental and cultural heritage during the Argyle mine’s lifetime. 

This includes keeping up civic plans to improve the economic and social prospects of Aboriginal people, as well as working with local people to cope with the cultural and environmental impact of the mining actions. Argyle has faith in its role and duty to create a long-term value for the community.   

Led by Kevin McLeish, the Chief Operating Officer of Argyle, the company shows concern and respect for the settings the business works in, and for the people affected by its actions. Today, Argyle is a major sponsor in the eastern Kimberley region for tourism, employment, infrastructure, and flow-on commerce, besides giving support to the local Aboriginal people.
