Sixty North: Initial Assays Return High-Grade Gold Values up to 62.6 gpt from the A-Zone and DD-Zone

4 September 2024

Vancouver, British Columbia--(Newsfile Corp. - September 4, 2024) - Sixty North Gold Mining Ltd. (CSE: SXTY) (FSE: 2F40) (OTC Pink: SXNTF) (the "Company" or "Sixty North Gold")

Sixty North Gold Mining Ltd. has received the first batch of assays from the recently developed A-Zone West Limb and the parallel DD-Zone located 12 m to the west. A second set of samples of the East Limb of the A-Zone were submitted August 27 with results anticipated in late September.

The newly recognized DD Zone had seven samples collected with the results as shown below:

Sample Date Zone Details Description Gold gpt

The seven samples average 17.24 gpt gold and have an average measured SG of 2.83 gm/cc over sample widths of 0.3 to 2 m.

Dr. Dave Webb, Ph.D., P.Eng., P.Geol., President & CEO, Director stated, "We are very happy to have confirmed the location of the A-Zone quartz veins of a size and grade as to be economically interesting. Our plan was to expose these veins in preparation for the mining and milling planned for 2025. The discovery of the DD-Zone is an unexpected bonus. Additional sampling will refine these results.

The DD Zone has returned an average grade of 17.24 gpt from seven samples, ranging up to 62.6 gpt gold/0.3 m. It is exposed over 17 m in the Main Ramp where it averages 2.0 m in width. The face of the Main Ramp hosts the DD-Zone where it is 2 m wide on the west-side of the ramp. The West Limb of the A-Zone is narrower than normal and will be tested along strike to confirm widths and grades.

The East Limb of the A-Zone appears to be well mineralized with assays anticipated in late September.

A total of 250 tonnes of mineralized material has been placed on a separate pile. The successful completion of this phase will support the company's acquisition and installation of the permitted 100 tpd mill and relevant infrastructure to restart processing on site. Twelve vein samples were submitted for specific gravity analysis (SPG-04) returning an average of 2.83 gm/cc."
