Northstar Corporate Strategy and Recent Events

• A strategy to develop a +1 million ounce mineral resource at the 100%- owned Miller Gold Property, situated 18 km southeast of Kirkland Lake, ON.
• Northstar has spent >$4.4M in exploration at the Miller Gold Property since IPO in late 2019, resulting in the discovery and expansion of the near-surfaceAllied Gold Zone, with numerous 70 - 750 Au gram/metre drill hole intercepts.
• Recently completed SRK Target Study* on the Allied and Vein 1 Gold Zones that reports an upper exploration potential range exceeding 500,000 ounces gold averaging 2.04 g/t Au. Excellent upsides with more drilling.
• Closed $1.4M private placement - December 20, 2022.
• Fully funded and permitted to conduct a Phase III Allied Gold Zone expansion drill program scheduled to commence in May 2023.

• The above Exploration Target estimate highlights the exploration potential of the known gold zones on the Miller Gold
  Property. The quantity and grades are purely conceptual in nature. Insufficient exploration has been carried out to define a mineral resource on the property. A qualified person has not done sufficient work to classify this Exploration Target estimate as current mineral resources and the Company is not treating this Exploration Target estimate as current mineral resources.
