Mining advocates are applauding the N.W.T. Geological Survey for its recent work mapping an under-explored area of the territory. Tom Hoefer, the executive director of the NWT & Nunavut Chamber of Mines, says the information could spur mineral exploration and help the N.W.T.’s slumping mining industry.

“The [economic] outlook in the future isn’t that great, and the reason why is we haven’t found enough new mines to offset the mine closures that are going to be coming,” he said. “And the reason for that is we’ve had flagging, or really low exploration investment for the last 12 years now.”

The N.W.T. Geological Survey released new data on Monday of a large swath of the Slave Geological Province, including an area known as the Point Lake greenstone belt. Point Lake is located about 300 kilometres north of Yellowknife, near the Nunavut border.

An airplane equipped with a magnetic sensor collected information about the 5,000 square kilometre survey area. “Simply put, this data tells us which parts of the rocks in these areas are more or less magnetic than others,” said Barrett Elliott, a diamond geologist with the N.W.T. Geological Survey.

“By combining this with what we already know about the rocks in the region, we can generate new and more detailed geological maps, and these maps show that some areas have greater potential than others to host certain types of mineral deposits.”
