Mining For Diamonds – History and Present J. Jakubec1 1 SRK Consulting, Vancouver, Canada, jjakubec srk.com. Introduction Alluvial mining for diamonds started in India and for centuries Alluvial mining was the primary source of diamonds. Hard rock mining of primary kimberlite on an industrial scale had only emerged with
Mining of a diamond-bearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ‘‘open-pit’’ or ‘‘open-cast’’ mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks.
Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. Venetia mine is an example of open-pit mining. In underground mining, miners tunnel into the earth’s crust through the kimberlite pipe.

The diamond mining process comes before the diamond ring. The diamond mining process is as old as the discovery of diamonds in India…this was approximately in the 9th Century BC. The exact origin of diamonds is still something of a mystery. Its know that diamonds were created by nature more than 3 billion years ago.
In 2004, the UN placed a decade-long embargo on Ivorian diamonds, and the country’s diamond exports fell to zero, according to the Kimberley Process. However, since the ban was repealed in 2014, the country’s diamond industry has flourished; the Ivory Coast produced 1,074 carats of diamonds in 2014, compared to 7,360 in 2017.
As it turns out, mining for diamonds is one of the most resource-heavy and time-consuming processes that companies have to invest their efforts in. Even with all our technological advances and engineering tools, diamond mining still incorporates a certain level of art and science combined.
Modified from Stornoway Diamonds presentation “ Diamond Exploration: A Multi-stage Process “ The two main methods for drill testing kimberlite anomalies are core-drilling and reverse-circulation RC drilling. Core drilling is based on a diamond coated drill bit that bores into the rock to provide sections of solid rock.
