The Gunnar Mine was an active uranium mine in northern Saskatchewan, Canada, located approximately 25 kilometres (16 mi) southwest of the community of Uranium City and approximately 600 km (370 mi) north of Saskatoon.

[1][2] This mine is situated on the Crackingstone Peninsula on the north shore of Lake Athabasca in the Beaverlodge Uranium District.

[2] In 2000, the Canadian Nuclear Safety Commission first visited the site to begin the remediation project of this abandoned mine.

These non-compliant acts were described as having "low safety significance," but issued enforcement notices[2] As of 2020, the mine was being decommissioned by the Saskatchewan Research Council who have a license to operate the site until 2024.

This meant that the mine had to accumulate a years worth of ore before the boat and barge season could begin due to ice and winter freeze.

[5] Due to this, Gunnar developed their own dedicated shallow draft tugboat to ship goods along a 440 km (270 mi) route in Alberta.

These government parties created detailed environmental impact assessments in efforts to plan for remediation.
