About the Company

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 NI 43-101, August 3, 2023 on SEDAR or https://sixtynorthgold.com/projects/technical-report/. 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 tpd 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 gpt gold or better (Discovery Mine with one million ounces of gold produced, and Sixty North Gold’s Mon Mine), and two that averaged 15 gpt or better for a total production of over 14 million ounces of gold (Con Mine and Giant Mine); (ref.
