Lynn Lake Gold District

Alamos Gold's Lynn Lake Gold Project, comprising the Gordon, MacLellan, Linkwood, and BT deposits, hosts combined Proven and Probable Mineral Reserves of 3.436 million ounces of gold at 1.25 g/t Au contained within 85.4 million tonnes, with additional Measured and Indicated Mineral Resources of 0.885 million ounces of gold at 1.27 g/t Au contained within 21.7 million tonnes, and Inferred Mineral Resources of 0.308 million ounces of gold at 0.80 g/t Au contained within 11.9 million tonnes.

The Lynn Lake Gold Project, currently under construction, is expected to average 186,000 ounces over its initial 10 years with total production estimated at three million ounces over the life-of-mine. Initial production is expected to commence in the first half of 2029. The Last Hope Gold Project is located approximately 10 km southeast of Alamos Gold's Linkwood and BT deposits.

Readers are cautioned that the Company has no interest in the Lynn Lake project and the proximity of the Last Hope Gold Project to Alamos Gold's deposits does not imply that similar mineralization or economic results will be encountered on the Company's property.

About 55 North Mining Inc.

55 North Mining Inc. is a Canadian exploration and development company advancing its 100% owned high-grade Last Hope Gold Project. The 2021 NI 43-101 mineral resource estimate ("MRE") for the Last Hope Gold Deposit is 71,100 ounces of Indicated gold resources at 5.41 g/t Au contained within 0.4 million tonnes and 273,800 ounces of Inferred gold resources at 5.48 g/t Au contained within 1.5 million tonnes. The deposit remains open both down-plunge and along strike, highlighting strong exploration potential for resource expansion through additional drilling.

The Mineral Resource estimate for the Last Hope Gold Project is based on the 2021 NI 43-101 Technical Report. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves. The estimate remains open down-plunge and along strike. Investors are cautioned that the Company has not completed a Preliminary Economic Assessment, Pre-Feasibility Study, or Feasibility Study on the Project and there is increased uncertainty and specific economic and technical risks of failure associated with any production decision based on the current mineral resource estimate.
