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.
Permafrost construction on permafrost owing to the change of soil properties of the ground on which structures are placed and the biological processes in permafrost, e.g. the preservation of organisms frozen "in situ". Building on permafrost is difficult because the heat of the building (or pipeline) can thaw the permafrost and destabilize the structure. Three common solutions include: using foundations on wood piles; building on a thick gravel pad (usually 1–2 metres/3.3–6.6 feet thick); or using anhydrous ammonia heat pipes. The Trans-Alaska Pipeline System uses heat pipes built into vertical supports to prevent the pipeline from sinking and the Qingzang railway
