Ekati Diamond Mine

The Ekati Diamond Mine (Ekati) is Canada's first surface and underground diamond mine It is located 310 km (190 mi) north-east of Yellowknife Northwest Territories and about 200 km (120 mi) south of the Arctic Circle near Lac de Gras Until 2014 Ekati was a joint venture between Dominion Diamond Mines (80%) and the two geologists who discovered kimberlite pipes north of Lac de Gras Get price



Rapid mining led to the kimberlite being mined-out and the mine closed by 1914 This means that no modern geological investigations were ever carried-out on probably the "archetypical" kimberlite Maps of the mine show that it had a pipe-like shape and that it probably consisted of diatreme-facies kimberlite (Clement 1982) Get price



The recently announced discovery of a previously unknown kimberlite pipe at Gahcho Ku Mine is just the latest in a series of discoveries that have the potential to extend operations at the diamond mine The 'Wilson' kimberlite discovery is located within the Tuzo pit design limits Get price

Park staff provide complimentary identification or rocks and minerals found at the park as well as diamond mining demonstrations and other interpretive programs More than 33 100 diamonds have been found by park visitors since the Crater of Diamonds became an Arkansas state park in 1972 Get price



Open pit mining began in late 1996 on the two largest pipes in the Kelsey Lake kimberlites The Kelsey Lake Mine was North America's first commercial diamond producer In 1998 the mine was put into limited production status and has remained that way since Location map of State Line Kimberlite district and "Diamond Peak" Get price


How to Visit a Diamond Mine

Nov 19 2013A diamond mine harvests the raw diamonds from a kimberlite pipe by starting at the surface and continuing further and further underground following the kimberlite For this reason a diamond mine often looks like a giant hole in the ground sometimes filled with water The mining is actually taking place under the hole Get price

In Search of Diamonds An Introduction to Kimberlite

How We Find Diamond Sources Kimberlite and Lamproite

This means that total kimberlite occurrences are tens of thousands of hectares of land-mass compared to 13 billion hectares of land on the planet of which 7% is located within Archean cratons Given that less than 1% of kimberlites will yield an economically-viable diamond deposit finding a viable diamond mine is a daunting task Get price
