Canadian diamonds a 20% ownership of the mine, and since its discovery and start of operation in 1998, Ekati has produced over 40 million carats of diamonds. The discovery and later success of this diamond mine caught the attention of other major mining operations, and more massive mines were opened and fully operational within 10 years. Located approximately 53 miles southeast of the Snap Lake Diamond Mine, the Gahcho Kue Diamond Mine Project is one of the richest diamond mines in Canada with an expected lifespan of 11 years. It is estimated that 54,000,000 carats will be recovered during the mine's lifetime.
Underground mine ventilation the permafrost heating may not take place to prevent melting the permafrost. "Cold mines" such as Raglan Mine and Nanisivik Mine are designed to operate below 0°C. The wet bulb temperature in any working place does not exceed 33.5°C and where the wet bulb temperature exceeds 30.5°C arrangements are made to ventilate the same with a current of air moving at a speed of not less than one metre per second; Underground mine ventilation Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases
