The proposed route for the Arctic Economic and Security Corridor all-weather road encompasses the wholly-owned Mon Gold Mine in the Northwest Territories, following a consensus agreement reached between the Yellowknives Dene First Nation and Tłı̨chǫ Government.

The 400-kilometre all-season highway is planned through the Slave Geological Province to the Nunavut border to connect with the Grays Bay Road and the Arctic Ocean, with the project having been referred to the federal Major Projects Office in March 2026.

“We are pleased that the broad corridor was planned to respect First Nation's values and preserve caribou habitat while at the same time linking lands of potential economic and security benefits to local communities and Canada as a whole. We note that the corridor, as selected, encompasses Sixty North Gold's wholly-owned Mon Gold Mine. We will do what we can to assist all levels of government in meeting their objectives for this proposed road.”

— Dr. Dave Webb, President and CEO

Sixty North Gold Mining Ltd. wholly owns the past-producing Mon Gold Mine in the Yellowknife gold camp, where historical mining in the 1990s extracted 15,000 tonnes of ore to depths of 15 metres. The company previously transported heavy supplies to the property using an annual winter road from Highway 4, while the proposed corridor is projected to eliminate winter road requirements.

“The all-weather road access to the Mon Mine is projected to significantly reduce our operating costs, by avoiding the need to build a winter road for heavy equipment and bulk supplies delivery, as well as shipment of concentrates out from the mine. Operating costs will be reduced by allowing for smaller, as-needed resupply of consumables. Environmental liabilities can also be reduced by keeping lower levels of fuel and explosive inventories on site.”

— Dr. Dave Webb, President and CEO

Realization of these operational changes remains subject to conditions including the receipt of necessary regulatory and third-party approvals and the timing of equipment and personnel mobilization. Sixty North Gold plans to extend the ramp at the Mon Gold Mine to allow for the development of deeper levels.
