The Ekati Diamond Mine started operations in 1998 and as of 2001 is North America's only operating diamond mine, producing $1.7 million of diamonds every day. The name "Ekati" comes from the Dene language and means "fat lake", but actually refers to white granite rock outcrops, resembling caribou fat! The mine is located about 300km northeast of Yellowknife in the arctic Barrens. The isolated location makes it even more attractive to use remote sensing for monitoring and mapping purposes. Just how can remote sensing data and technology help a mining operation like this? See our sample images of the Ekati mine site, analyzed/interpreted to:

1. map the surrounding natural environment (to help minimize environmental impact),
2. monitor development (assess changes to the environment over time),
3. overview the whole site (for administrative planning purposes),
4. observe site features for mining & engineering purposes:

• Panda Pit
• Main Camp and Processing Plant
• Waste rock storage
• Airstrip

Question: The wider road to the east of the airstrip is Misery Road which leads to the Misery (kimberlite) pipe; it takes an apparently unnecessary "S"-shaped swing. Is it really unnecessary? Why doesn't the road go straight?
