Sixty North GOLD Announces Drill Intersection of Massive Sulphides Returns Anomalous GOLD Values

Drill Results

SIXTY NORTH GOLD ANNOUNCES DRILL INTERSECTION OF

MASSIVE SULPHIDES RETURNS ANOMALOUS GOLD VALUES

VANCOUVER, British Columbia -- (Newsfile Corp. – May 5, 2025) Sixty North Gold

Mining Ltd. (CSE: SXTY, FKT: 2F40, OTC-Pink: SXNTF) (the “Company” or “Sixty

North Gold”) announces the first drilling results in its Volcanogenic Massive Sulphide

(“VMS”) drill program. The Company has successfully tested one of the six targets

identified from the VTEM Plus © geophysical survey and subsequent analysis of that

data by Mira Geosciences (“Mira”).

Dr. Dave Webb, CEO, states, “We are pleased that the first two drill holes have

identified massive and semi-massive sulphide horizons in the first of six targets to be

tested. Drilling was suspended early due to warmer weather making our snowmobile

trails inaccessible.

“Assays reveal this horizon to be composed primarily of iron sulphides with limited but

continuous enrichment of precious metals at subeconomic levels. No significant base

metal enrichment was encountered. The upper conductor we tested is now interpreted

to be the iron-rich cap-rock of the VMS system. We are now confident that we are in a

VMS system and that geophysics correctly identifies where the lenses are located. The

Company can now focus on the lower horizon to determine if these conductors carry

grade similar to that found in the 5656 Zone along strike to the north or the Likely or

Homer Lake Deposits to the south. We believe the lower conductor represents the best

target for further work.”

Webb further reports that “We have six targets we plan on testing, with the lower

horizon conductors now being the highest priority as they are on strike and within the

same horizon as the well-mineralized 5656 Zone. The attached Figure 1 shows our

planned drill program. Our first hole at Location A was setup on lake ice to test the

lower horizon, but upon completion of set-up, significant and unexpected water

overflowed the ice forcing a rapid demobilization from this target and onto the Set up B

that had been prepared for drilling. The two holes completed were from Location B.

Additional drill holes are planned on the lower horizon.”

The proximity to the Bluefish Hydroelectric Power Plant, and the road network from

Yellowknife makes these targets appealing for potential development in the future, with

reduced infrastructure costs. The VMS zones provide the Company with an exciting

diversification and a potential portfolio of strategic metals, in addition to our planned

underground Mon Gold Mine on the same property.”

Six conductors were modeled by Mira, including an exposed VMS showing, the 5656

Zone which grades 1.0 gpt gold, 203 gpt silver, 0.59% lead and 0.96% zinc over

0.45 m in trench samples over 150 m of strike (see news release November 6,

2018). A cluster of much larger, more prominent conductors along strike include the

Lower Horizon which includes the Mac Tuff showing 2 km to the south (not on the Mon

Property). The Upper Horizon occurs in a mixed mafic and felsic tuff horizon, 300 m

stratigraphically above the Lower Horizon.

Core was delivered to camp where it was logged by a registered Professional Geologist.

The core was sawn and half samples were bagged and tagged and delivered to ALS

Global in Yellowknife NWT with suitable Certified Reference Standards and Blanks.

These samples were crushed and pulverized (CRU-31, PUL-31) in Yellowknife and

shipped to ALS Global’s Geochemistry site in North Vancouver where they were

analyzed by ME-ICP61a, AU-AA23, and OA-GRA08. All standards reported acceptable

results. ALS Global is a certified laboratory, independent of the Company.

About the Company

Sixty North 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 (NI 43-101,

August, 2023). 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 stockpile the vein material on surface. Upon

confirmation of the grade and tonnage, the Company plans to bring a permitted mill in to

process this and continuing mined material.

The VMS target, and the shear zones are separate targets on the property and will

continue to be tested as circumstances permit.
