SIXTY NORTH GOLD ADVANCES DEVELOPMENT AT MON GOLD MINE, NWT

Activities to commence gold production this year on Sixty North Gold Mining Ltd.'s wholly owned Mon gold mine, Yellowknife, NWT, are on schedule with only modest delays to date.

Sixty North Gold has assembled its camp, and has received authorization from inspectors to clear the mill pad and commence constructing roads to the dry stack tailings facility. Operations are proceeding as planned, and a revised design and construction plan for the mill has been submitted to the MVLWB for review. Discussion with the MVLWB on the water management plan will continue, including the submission of an independent review of the past 25 years of sample results recognizing no significant change in water conditions after material wildfire seasons in 2023 and other years. Drought conditions in advance of all of the wildfire seasons reduced or eliminated water in sample sites, resulting in missing data.

Its plans to proceed include:

1. Assemble the camp and infrastructure (three or four weeks):
   1. Crews are on site and active.
2. Clear the mill pad of the blasted rock and use this rock for road construction purposes (two weeks):
   1. Crews are on site and will commence within the next two weeks.
3. Commence assembling the mill (nine to 13 weeks):
   1. Crews with support can commence once approvals of the design and construction plan mill are approved (resubmitted).
4. Commence extracting mill feed:
   1. This will commence one week prior to mill start-up.
5. Commence operations:
   1. This requires approvals of all remaining management plans (all management plans have been submitted at least once; the water and groundwater management plan is subject to board directive for two years of post-2023 wildfire baseline sampling).

All mining and milling equipment, necessary supplies, and crews are on the property executing items 1 and 2.

Dave Webb, president and chief executive officer, reported: "We had been operating under an advanced exploration plan under a board directive dated Oct. 24, 2022, which allowed for underground development, bulk sampling, infrastructure construction and limited processing.

"We are moving the project forward with full support of the federal, territorial and indigenous governments, subject to the MVLWB regulations. The MVLWB is completing their review of the various remaining management plans, and will be requesting clarification and revisions as needed. We feel that we have been making progress and that we can meet the current requirements to move through the next steps to production."

The company is well financed and has engaged external technical experts to assist in the completion of the remaining plans. The mine site had been subjected to an archeological overview assessment including field visits in 2016, but, in June, 2026, the company initiated and completed a more extensive archeological impact assessment to provide more confidence to the local first nations that the Mon gold mine will have minimal and acceptable impacts.

About Sixty North Gold Mining Ltd.

Sixty North Gold is developing mining operations on its 100-per-cent-owned Mon gold project. The company has designed its operation to be as sustainable as possible. In a first for the Yellowknife gold belt, its environmentally friendly mill is a crush, grind, gravity, float, filter dry stack operation.

• The gold-bearing rock is selectively mined from underground producing minimal waste rock. The mine currently has one three-metre-by-four-metre access portal, and will have one two-metre-by-two-metre raise for secondary egress. Mill feed is developed and trucked to surface as needed.
• The gold-bearing rock is crushed in a closed two-stage circuit before being fed into a ball mill where it is ground to p80 minus 150 mesh. Sixty has opted for a fairly coarse grind because it can recover greater than 95 per cent of the gold as shown in testwork, and the tailings are therefore coarser and easier to deal with than fine ground rock.
• Gold is recovered in a gravity circuit where the concentrate can be melted to form raw gold or dore bars. The gravity tailings pass to a flotation circuit where the residual gold is processed, resulting in up-to-95-per-cent cumulative gold recoveries in the two circuits. The gold flotation concentrate and all associated sulphides are collected into megabags for shipment off-site for sale or further processing.
• The tailings are filtered in pressure filters to remove 80 to 85 per cent of the water for recycling. The residual tailings are damp sands composed of quartz, carbonate and minor rock fragments that get trucked to a dry stack facility where they can be placed and monitored.

The 100-tonne-per-day mill will require 15 to 20 cubic metres of makeup water each day that will be sourced first from mine water discharge and lastly from fresh sources. Net, the Mon mine should use less water than a modest diamond drill program and have no liquid slurry to manage, and, net, the mill will have reduced freshwater usage by greater than 85 per cent.

Mining at the Mon gold mine in the 1990s extracted 15,000 tonnes of ore to depths of only 15 metres below surface, recovering an estimated 15,000 ounces of gold (company technical report National Instrument 43-101, Aug. 3, 2023, on SEDAR+). Recently, underground development has intersected the productive A-zone 17 metres below the historic stopes as planned. A newly discovered zone, the DD-zone, is exposed 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 volcanogenic massive sulphide deposits, the large shear zone-hosted gold targets and the critical-element-enriched iron oxide copper/gold-style mineralization 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 company technical report NI 43-101, Aug. 3, 2023). The Yellowknife gold belt is a historic gold producing camp where all of the mines commenced production at fewer than 100 tonnes per day. Yellowknife has the people, services and experience to bring this Archean gold belt back to life.

We seek Safe Harbor.
