Drill Results

55 North Mining Inc. 2021 Year-End Update and 2022 Plans

Toronto, Ontario – December 16, 2021 - 55 North Mining Inc. (CSE: FFF) (“55 North” or the

“Company”) is pleased to provide a brief overview of its accomplishments during 2021, and its

plans for 2022. We are extremely pleased with our progress to date on our Last Hope Gold

Project, a high-grade gold project 10km away from Alamos Gold’s 2Moz Lynn Lake Project in

northern Manitoba.

The 2021 year in Review

2021 was a year of many value-building activities. We completed a 29 hole winter drill program

which returned many high-grade intercepts including 19.25 g/t over 15.70m and 7.59 g/t over

7.00m. These results were used to complete an updated NI 43-101 compliant resource estimate

which featured Indicated Mineral Resources increasing 87% to 71,100 ounces from 38,000

ounces, and Inferred Mineral Resources increasing 48% to 273,800 ounces from 184,100 ounces.

In addition, our drill program extended high-grade shoot mineralization up and down-plunge,

extended the deposit strike length by 200m, in-filled within the current resource block model, and

confirmed multiple en-echelon gold zones. The deposit remains open along strike to the

southeast, as well as down plunge along 2 high grade shoots.

This excellent result was achieved despite difficult operating conditions. Last winter began with

early warm weather, followed by cold weather accompanied by a heavy snowfall which insulated

the lakes and resulted in thinner than usual lake ice, precluding the use of a winter road. The net

result was the exclusive use of helicopters for drill transportation and servicing, and drilling costs

approximately twice those we would normally incur had we been able to utilize winter roads.

In addition to a near doubling of resources, we are considering a scenario that has the potential

to significantly increase the value of the project. Our new resource estimate includes high grade

Potential Surface Mineable Mineral Resources of Indicated: 82,800 tonnes grading 5.08 g/t for

13,500 ounces which are all within 20 metres of surface. This portion of the resource could

potentially be mined using low capex and opex trench (slot) mining. In this scenario, currently

being studied, blast cuts would be mined using a narrow remotely operated loader feeding a

bucket (hopper) lowered from a crane. This potential mining scenario would have an immense

positive impact on upfront cashflow of the project.

Plans for 2022

Our Phase 3 exploration program, planned for 2022, will consist of: a) in-fill drilling within the high-

grade shoots to upgrade and increase the resources in these areas, b) step -out drilling along

strike to the southeast, and c) extension drilling down plunge along the high-grade shoots to add

resources as we extend the depth of the deposit from the currently relatively shallow 520m. In

addition, we have applied for a permit to construct a 5.6 km access road from an existing all -

weather road, in order to avoid our re liance on weather-dependent winter ice roads, and

expensive helicopter-assisted drilling. In order to fund this program, we will be initiating

flowthrough financing, and non-flowthrough financing several months into the new year.

About 55 North Mining Inc. and the Last Hope Gold Project

55 North Mining Inc. is an exploration and development company advancing its high-grade Last

Hope Gold Project located in northern Manitoba, Canada. The Last Hope Gold Project contains

an Indicated Resource of 0.4 Mt grading 5.41 g/t Au for 71,100 ounces Au, and an additional

Inferred Resource of 1.5 Mt grading 5.48 g/t for 273,800 ounces Au (see Technical Report titled

“NI 43-101 Technical Report and Updated Mineral Resource Estimate on the Last Hope Property,

Lynn Lake Northern Manitoba, Canada” dated No vember 11, 2021). Excellent exploration

potential exists down plunge and along strike. Also, the Company is considering a scenario

whereby it could mine the top 20 metres of high-grade mineralization of this resource (Near

Surface Mineral Resource: Indicated: 13,500 ounces grading 5.08 g/t) utilizing simple, potentially

low-cost trench mining methods. Although the analysis process is still in its early stages, this

option could potentially provide the opportunity for a low capex and opex method for upfront

extraction of a portion of the Mineral Resource, thereby having a very positive impact on upfront

cashflow.
