Sixty North Gold Mining Ltd. (CSE: SXTY,OTC:SXNTF) (FSE: 2F40) (OTC Pink: SXNTF) (the "Company" or "Sixty North Gold") is pleased to provide an update on its plan to commence gold production this year on its wholly-owned Mon Gold Mine, Yellowknife, NWT.

Construction of the entire length of our winter road from Highway 4, 20 km east of Yellowknife to our mine site is now completed and ice thicknesses are increasing quickly with late February temperatures of between -20 and -41^oC. Maintenance of the road by clearing snow and flooding portages will continue. Crews are now mobilizing to site to commence moving equipment onto the property.

The Company's mill shipment from China is now expected to arrive at Deltaport in the Greater Vancouver Area on March 6, 2026, for further transshipment by rail to Edmonton and truck to Yellowknife, NWT and the mine. Sixty North Gold plans to start assembly of the mill in late April with initial commissioning of the mill planned in late June or early July. We plan to operate this 100 tpd mill 24/7, treating material extracted from the second level of the A-Zone vein below the historic stopes. The DD-Zone will be evaluated for potential stope development, and we plan to extend the main ramp to the third level to establish another mining site.

About the Company

Sixty North Gold is developing mining operations for gold on its 100-per-cent-owned Mon Gold Project. Mining in the 1990's 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/). Recently, underground development has intersected the productive A-Zone 17 m below the historic stopes as well as a newly identified zone, the DD-Zone in the main ramp. The company plans to develop and mine stopes in the East Limb, West Limb and DD Zone and to extend the ramp to allow for the development of deeper levels.

The silver-rich VMS deposits (https://sixtynorthgold.com/projects/volcanogenic-massive-sulphide-vms-deposits/), the large shear zone-hosted gold targets (https://sixtynorthgold.com/projects/shear-zones/), and the critical-element-enriched IOCG-style mineralization (https://sixtynorthgold.com/projects/iocg-target/) 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. Company Technical Report NI 43-101, August 3, 2023). The Yellowknife Gold Belt is an historic gold producer and hosts the people and experience to bring this Archean gold belt back to life.
