About Sixty North Gold Mining Ltd.

Sixty North Gold is developing mining operations for gold on its 100-per-cent-owned Mon gold project, which extracted 15,000 tonnes of ore to depths of only 15 metres below surface, recovering an estimated 15,000 ounces of gold in the 1990s (company technical report, National Instrument 43-101, Aug. 3, 2023, on SEDAR+). The North Ramp has been reopened and has been extended to the target portion of the vein. The company plans to develop stopes in the East Limb, West Limb and DD zone to extract and to feed a 100-tonne-per-day gravity flotation mill.

Additional gold, silver and base metal targets occur on the property, and will be explored and developed as warranted.

The Yellowknife gold camp hosts two mines that averaged 30 grams per tonne gold or better (Discovery mine with one million ounces of gold produced and Sixty North Gold's Mon mine), and two that averaged 15 g/t or better for a total production of over 14 million ounces of gold (Con mine and Giant mine) (refer to the company technical report, NI 43-101, Aug. 3, 2023).

The technical content of this release has been reviewed and approved by Dr. D.R. Webb, PGeol, president and chief executive officer of Sixty North.
