FATHOM ANNOUNCES COMPLETION OF DRILLING AT GOCHAGER LAKE AND DRILL

TARGET IDENTIFICATION AT THE ALBERT LAKE PROJECT

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

ANY FAILURE TO COMPLY WITH THIS RESTRICTION MAY CONSTITUTE A VIOLATION OF U.S. SECURITIES LAWS

Calgary, Alberta – February 28, 2023 – Fathom Nickel Inc. (the "Company" or "Fathom") (CSE:FNI) (FSE:

6Q5), (OTCQB: FNICF) is pleased to announce that the Q1-2023 drill program at the Gochager Lake Project

has been completed. Equipment and personnel are currently being remobilized to the Albert Lake

Project. Diamond drilling is expected to commence at Albert Lake by March 3.

Commenting on the Gochager Lake Exploration Program, Ian Fraser, CEO and VP Exploration stated, “We

are very pleased with the outcome of both the drilling and BHEM initiatives at Gochager Lake. The initial

drillhole confirmed the presence of mineralization previously identified in historic drillhole IVY-67-012, and

the second drillhole also confirmed the Gochager Lake deposit style of mineralization and provided an

excellent platform for the BHEM surveys. As expected, the BHEM tool has proven extremely useful in

identifying off-hole conductors. We eagerly await assay results which will be released upon receipt and

interpretation, expected in early April. Our attention now turns to the Albert Lake project where we will

be targeting several very exciting priority areas including the Tremblay-Olson Claims area.”

Summary

• Q1-2023 drill program at Gochager Lake Project completed.

• 2 Drillholes completed at Gochager; both intersected broad zones of disseminated, semi-

massive to massive sulphide mineralization; results expected by mid-April.

• Albert Lake Project drilling to commence by March 3, 2023.

• Q1-2023 drilling at Albert Lake will initially focus around the Tremblay-Olson Claims area.

• The Tremblay-Olson Claims area (NIC-5 and Tremblay-Olson) had returned the highest

concentration of metals-in-soil collected to date at the Albert Lake Property (Press Release Jan.

17, 2023)See also Figure 1.

Gochager Exploration Program

The Q1-2023 exploration program at Gochager was designed around two primary objectives: 1) drill

testing of the reported results from a historic drillhole (IVY-67-012) that encountered mineralization over

a 290-meter zone, and; 2) probe both current and historic drillholes with a borehole electromagnetic

(“BHEM”) tool to determine the existence and extent of off-hole conductors.

We are pleased to announce success in meeting both objectives. Drillhole GL23003 was drilled to a depth

of 336 meters; GL23004 was drilled to a depth of 389 meters. Both holes intersected broad zones of

disseminated, semi-massive to massive sulphide mineralization. Three historical drillholes were also open

to bottom and were probed with induction and fluxgate probes. The r2023 drillholes were also probed

with both systems. Several off-hole responses were detected including, importantly, a strong response

outside the area of known mineralization. T he Company continues to interpret and model these data

which will form the basis for future exploration and drilling programs.

Core samples are currently being prepped for shipping to ALS Global’s Vancouver laboratory. Samples

will be assayed for the full suite of base and precious metals including, importantly, cobalt. Historic

samples were never systematically sampled for cobalt in spite of reported grades as high as 0.143% Co

from selected assays retrieved from historic drillhole IVY-67-12 available at the La Ronge Core Library.

Albert Lake Exploration Plan

Further commenting on the Albert Lake Exploration Program, Ian Fraser, stated, “We are excited to drill

test the favourable soil geo-chem targets that we have defined at the Tremblay-Olson Claims area. The

soil geochem, the coincident gradient MAG and MAG inversions, VTEM and AirTEM along with the recently

completed gravity survey data defines a very favourable exploration target along trend and to the

southwest of the historic Rottenstone deposit. We look forward to confirming that the metal (Ni, Cu, Co,

Mg, Cr and Pd, Pt) contained in soils at the Tremblay-Olson Claims area is the result of a mineralized

ultramafic source”.

B-Horizon soil geochemistry has now defined a multi -element anomaly that encompasses all known

mineralized ultramafic occurrences and deposits, most notably, the historic high -grade Rottenstone Ni-

Cu + PGE deposit (see Figure 1). This anomalous feature now has a strike length in excess of 5 kilometers

and a width up to 1 kilometer. Ongoing interpretation within this zone has defined favourable

stratigraphy that is comparable to that which is host to the historic Rottenstone Mine as well as Fathom’s

recently discovered Bay-Island Trend. The stratigraphy also hosts the necessary structural traps that act

as the trapping mechanism for the magmatic nickel deposits thus far defined on the Albert Lake property.

The focus of the exploration strategy at Albert Lake for the Q1-2023 program is centred on the Tremblay-

Olson Claims area anomaly(s). Within the Tremblay-Olson Claims area, the robust, multi-element soil

geochemistry anomaly(s) is directly coincident with recently completed gravity, historic VTEM, gradient

MAG and AirTEM data sets. Fathom will be drill testing these target areas beginning in the first week of

March.

The priority target areas for the Q1-2023 Albert Lake program are as follows:

Nic-5 – The Nic-5 area has the most robust multi-element soil geochemistry anomaly(s) encountered thus

far at the Albert Lake Project. Individual soils collected in the Fall of 2022 returned up to 497ppm Ni,

547ppm Cu , and one soil sample with a combined 1.21 g/t 3PE (platinum -palladium+gold). Historic

drillholes dating back to the 1960’s intersect ed ultramafic rock of varying widths with some holes

containing elevated nickel and copper within non -ultramafic rock . Fathom’s exploration team has

evaluated MAG, EM and recent gravity data plus inversions (MAG, gravity) collected within the Nic-5 area.

All data sets define anomalies coincident with the multi-element soil geochemistry anomaly(s). Fathom’s

interpretation of all data sets, and in particular the soil geochemistry is indicative of an ultramafic source

occurring within the Nic-5 area. Nic-5 is the highest priority drill target area during the Q1-2023 program.

Two to three drillholes are planned for this area.

Bay-Island Trend Extension – The Bay-Island Trend, which occurs 400 -500 meters west – northwest of

the historic Rottenstone deposit, defines a 300+ meter mineralized ultramafic body discovered by drilling

in 2021-2022. This structurally controlled ultramafic intrusion remains open along trend to the northeast.

Gravity and MAG . together with their respective inversions, define a fold nose -like feature 650 meters

along strike of where the 2022 drilling stopped. Structural traps and an interpreted fold hinge/nose is an

ideal trap for a mineralized ultramafic body to occur. There is a coincident VTEM signature occurring on

the immediate shore to the northeast and favourable/anomalous soil geochemistry occur s immediately

along the shoreline. This priority drill target will be drilled from the ice.

TO-South – TO-South refers to a coincident deep MAG/gravity target with a strong localized multi-element

soil geochemistry anomaly occurring along trend of all known ultramafic occurrences southwest of the

historic Rottenstone deposit. The enclosed Ni in soil map illustrates a strong Ni anomaly at this location.

Fathom Nickel Inc.

The recently completed gravity survey marks a strong increase in density at this location. One drillhole is

planned at the TO-South target area.

Rottenstone Mine Southwest Extension – Time and budget permitting , Fathom will test the northeast

continuation into the lake from the Nic -5 area, along trend to the historic Rottenstone deposit. MAG,

historic surface EM and g ravity signatures are suggestive of a possible ultramafic body/intrusion in this

area. Furthermore, this planned drillhole will test the footwall of the F -Fault. The Rottenstone deposit

occurs in the hanging wall and is in contact with the F-Fault. A drillhole in this area, followed by a BHEM

survey, would test this possible footwall offset.
