Calgary, Alberta - June 7, 2021 – Fathom Nickel Inc. (the "Company" or " Fathom") (CSE:FNI) (FSE:

6Q5), announces completion of 9- hole, 1,232 metre winter drill program at Albert Lake Nickel, Copper,

Cobalt, PGE Sulphide Project in Saskatchewan (the “Q1-2021 Program”). The Q1-2021 Program resulted

in (1) confirming an extension to the historic Rottenstone deposit (the “ Rottenstone Extension ”); (2)

discovery of new ultramafic mineralization 550m northwest of the historic, high- grade Nickel, Copper,

Cobalt + PGE Rottenstone Mine (the “Island Showing Area Discovery”); and (3) c ompletion of a high-

resolution gradient magnetic survey consisting of over 9,000 line-km (the “Airborne Survey”). In addition,

Fathom will be commencing its summer field program on June 15, 2021 with a drill program planned and

expected to commence the last week of August (the “Summer/Fall 2021 Exploration Program”).

The brief Q1- 2021 Drill Program was designed around two primary objectives : (1) to confirm the south-

southwest extension of the historic Rottenstone deposit (the possibility of a southwest extension was initially

identified during a drilling campaign completed in 2016) ; and, (2) to drill and test the high priority Island

Showing target area.

“We are very pleased that the Q1- 2021 drill program accomplished both of our primary objectives”, said

Brad Van Den Bussche, Fathom’s President & CEO. “We have confirmed, through our geotechnical data

compilation initiatives and drilling south of the Rottenstone Mine that not only is the Rottenstone deposit

larger than previously recognized, but that we have developed a framework to identify additional

Rottenstone-like deposits. This framework will be instrumental in helping us pursue new discoveries such

as the mineralized drillhole AL21021, located 550m from the historic Rottenstone Mine. This is a fantastic

discovery - it is the first ever intersection of significant ultramafic, nickel sulphide mineralization outside of

the historic Rottenstone deposit. We are very encouraged by both the thickness of the intersection and the

positive off-hole BHEM conductor to the south.”

Q1-2021 Drill Program Summary Results

Rottenstone Extension:

o Drillhole AL21017 intersected 18.08m of 0.68% Ni, 0.51% Cu, 0.02% Co, 1.39 g/t Pd- Pt

(Table 2 / Figure 1)

 Including 2.53m of 1.79% Ni, 2.09% Cu, 0.06% Co and 2.99 g/t Pd-Pt

 Including 1.48m of 2.29% Ni, 1.68% Cu, 0.07% Co, 3.60 g/t Pd-Pt

o AL21024 intersected 7.47m of 1.06% Ni, 0.88% Cu, 0.03% Co and 4.36 g/t PGE

 Including 4.00m of 1.46% Ni, 1.39% Cu, 0.05% Co and 7.32 g/t PGE

 Including 1.01m of 1.71% Ni, 1.21% Cu, 0.05% Co, 1.94 g/t Pd, 18.10 g/t Pt (20.76

g/t PGE)

Island Showing Area Discovery:

o AL21021 collared on lake ice 550m north-northwest of Rottenstone Mine intersected 9.23m

of Rottenstone-like, ultramafic mineralization at a downhole depth of 136.32m : 0.20% Ni,

0.11% Cu, 0.01% Co and 0.14 g/t Pd-Pt.

o Borehole EM (BHEM) survey data at this new discovery , together with subsequent

modelling indicates a plunging body, increasing in conductivity south of the drillhole

potentially indicative of increased mineralization in a southerly direction.

o The Company interprets this discovery drillhole to be indicative of and similar to the lower

grade mineralization that envelopes the Rottenstone deposit. The intercept in AL21021 is

the first ever drilled occurrence of anomalous ultramafic hosted, mineralization that was

not in the immediate vicinity of the historic Rottenstone Mine.

Fathom drill programs in both 2016 and Q1- 2021 (Figure 1) oriented south-southwest of the historic

Rottenstone Mine1 now confirms a previously unrecognized extension of 40m in a south-southwest direction

that remains open. In addition, drillhole AL21021 intersected 9.23m of mineralized ultramafic host rock

550m north- northwest of the Rottenstone deposi t indicating the potential for another Rottenstone- like

deposit.

Figure -1 Fathom 2016 – 2021 Drillhole Plan Map

Ian Fraser Fathom’s VP Exploration commented, “The Q1- 2021 drilling has confirmed that there is more

Rottenstone-type mineralization extending 40m south- southwest of the historic Rottenstone Mine and

remaining open. However, i t is important to note that expanding the Rottenstone deposit is not the

Company’s exploration focus. The drilled extension has allowed us to further enhance our understanding

of the geologic setting and specifically that these types of deposits are zoned; meaning that they grade

outwards from a higher-grade net-textured core. The knowledge gained will be instrumental as we seek to

recognize when we are proximal to the higher -grade cores of these types of deposits. Drillhole FMRS16-

003 which was collared less that 10m from the historic Rottenstone Mine has a very similar grade and

mineral composition to drillhole AL21021. We are confident our discovery in AL21021 is an indication of

higher-grade mineralization proximal to this drillhole. Recognizing this framework and geologic setting will

be critical in assisting with the identification of additional Rottenstone-like discoveries”.

Airborne Survey and Summer/Fall Exploration Program

In addition to the Q1- 2021 Drill Program, in April the Company also completed a high- resolution gradient

magnetic survey consisting of over 9,000 line- km over substantially the entire 90,000ha Albert Lake

Property. The survey data is currently being interpreted and will be a valuable tool for planning the

Summer/Fall-2021 Exploration Program. The Summer/Fall-2021 Exploration Program will commence on

June 15, 2021. It is expected to include an airborne EM survey over key targets including the Island Showing

area discovery, as well as extens ive mapping, sampling, prospecting and B -horizon soil geochemistry. In

addition, multiple historic drillholes will be probed for the first time and re- probed with BHEM. A diamond

drill program of between 4,000 and 5,000 metres is planned and expected to commence in the last week

of August 2021 and continue through the start of winter freeze- up at the end of October 2021. The

Company’s drill contractor has agreed to leave the drill rig onsite through to the end of April 2022, thus

eliminating both the cost and possible delays that can result from a second mob/de- mob process.

For drillholes FMRS 16-001 – FMRS16-008, FMRS16-011 drill core samples were split by rock saw with

one half retained in the core box and remains on the Albert Lake property. The other half was placed in

plastic samples bags with pre-numbered sample tags. All samples were transported to TSL laboratories in

Saskatoon, SK by company personnel for assaying. TSL is a Standard Council of Canada Accredited

Laboratory (538) and independent of Fathom. At TSL a multi-acid digestion followed by multi-element (41)

ICP-MS analyses type of assay was utilized. Over limit Ni, Cu was assayed by Ore Grade – AA finish and

select samples assayed for Pd, Pt, by 30g Fire Assay with ICP Finish. Fathom inserted certified blanks and

standards at intervals consistent with industry standards into the sample streams of all samples collected

for assay.

Drillhole FMRS16-009, FMRS16-010 drilled in 2016 for the purpose of a possible metallurgical study were

assayed in 2021 at ALS. For drillholes drilled Q1 2021, drill core samples were split by rock saw wit h one

half retained in the core box and remains on the Albert Lake property. The other half was placed in plastic

samples bags with pre- numbered sample tags. All samples were transported to ALS receiving facility in

Saskatoon and assayed at ALS Vancouver. ALS is an accredited laboratory ISO/IEC 17025; 2017 and

independent of Fathom. All samples were assayed by a four-acid digestion (ME-ICP61), 33 elements, ICP-

AES finish, overlimit Ni, Cu by ME -OG62, Pd, Pt and Au by Fire Assay (30g) PGM- ICP27 with ICP -AES

finish. Full suite PGE analyses was performed at ALS facility Johannesburg, South Africa where palladium,

platinum, rhodium, osmium, iridium and ruthenium was assayed by Nickel Sulphide Fire Assay Fusion

followed by ICP-MS finish (PGM-MS25NS).

About Fathom Nickel Inc.

Fathom Nickel is a resource development and exploration company that is targeting high- grade nickel

sulfide discoveries for use in the rapidly growing global electric vehicle market.

The Company is accelerating exploration on its flagship Albert Lake Project, host to the historic

Rottenstone mine, which is recognized as one of the highest ‐grade (Nickel, Copper, Platinum group

metals) deposits of its type ever mined in Canada. The Albert Lake Project consists of over 90,000 ha of

mineral claims located in the Trans-Hudson Corridor of Saskatchewan, which is home to numerous world-

class mining camps.

1 The Saskatchewan Mineral Deposit Index #0958 reports that 26,058t grading 3.23% Ni, 1.63% Cu, 9.63 g/ t Pd-Pt+Au was

recovered from open pit mining 1965- 1969. The reliability of this historical data cannot be confirmed by the Company. The

resource extraction is not considered NI 43-101 compliant by the definition of a “mineral resource”. However, as evidenced by

the open pit mine existing on the property, mining has taken place.
