Corporate HighlightsSecular Bull Market

in Nickel

Nickel demand expected to expand 125% from 2.0 million tonnes annually in 2020 to over 4.5 million tonnes in 2030 Demand for Class 1 Nickel further underpinned by growing penetration of electric vehicles which is expected to account

for 59% of Nickel demand in 2030 up from 5% in 2020

>80,000 Ha. of Underexplored Land package

(Historical grades of 3.23+% Ni)

Albert Lake Project consists of 90,000 Ha. drill ready exploration lands located in Saskatchewan, Canada with over 80,000 Ha. currently unexplored

Hosts the historic Rottenstone Mine, an open pit, high grade Ni Sulphide past producer (1965 to 1969) with a 3.23% Ni Grade plus associate metals (Cu + PGE)

Deposits of high-grade Ni – Cu + PGE mineralization, such as the Rottenstone deposit, do not exist in isolation which points to a to much larger potential Ni - Cu + PGE resource on the land package

Unique Mineralization

Unique mineralization of historical Rottenstone deposit. 2017 Metallurgical Sample returned average grade: Ni (4.06%), Cu (1.37%), Co (0.097%), Pd (5.79 g/t), Pt (4.15 g/t), Rh (0.20 g/t), Os (0.13 g/t) Ir (0.11 g/t), Ru (0.06 g/t) and Au (0.57g/t). Total PGE’s + Au = 11.02 g/t**

Bulk sample metallurgy showed metal recoveries of greater than 90% , Ni, Cu, Co and >80% Pd-Pt

Very intermittent exploration 1929 – 1960

Original historic resource estimate (1946) 45,000 t of 2% Ni, 1% Cu 5.5 g/tPd-Pt + rhodium*

1970-1998 limited exploration

1999-2003 exploration by uranium exploration company

2015 project core concessions acquired by Fathom**

Fathom expanded the land base from ~ 10,000 Ha. to the current 90,127 Ha. Amassed and compiled historical data 1929 – 2018 Necessary permits in hand Exploration Model and Strategy in place

Engaged and have excellent relationship with First Nations

Source: Company Materials, FactSet, as of June 8th 2021 *The reliability of the historical data and resource estimate presented here cannot be confirmed by the authors, nor can the assumptions, parameters andmethods used to prepare the estimates. The estimate is not considered NI 43-101 Compliant by the definition of a “mineral resource” and further work isrequired to verify the historical estimate as a current mineral resource. Furthermore, records suggest (Saskatchewan Mineral Deposit Index #0958) thatsome of this historical resource has been exploited making a delineation of this mineral resource impossible. Fathom Nickel is not treating the historicalestimate as a current mineral resource.

* The reader is cautioned that Fathom Minerals has not done sufficient work to validate or classify the historical grades at the Rottenstone Mine. The historic grades are not NI 43-101 compliant and should not be relied on by investors. It is uncertain if further exploration will result in a Mineral Resource

Nickel in EV Battery Technologies

Two types of lithium-ion batteries dominate EV batteries –Nickel-Manganese-Cobalt (”NMC”) and Nickel-Cobalt-Aluminum (“NCA”).

NMC used by nearly every EV manufacturer globally with theexception of Tesla, which uses NCA.

Why Nickel for EV Batteries? Ni Use in EV Batteries

Battery Chemistry

New efforts underway to tweak battery chemistry from 33% Ni to 80% Ni

Present day batteries employ 60% Ni, 20% Mn and 20% Co – 6:2:2 ratio

Advancements are pointing towards batteries containing 80% Ni

Battery Composition

A 60kwh NMC811 battery needs 5kg of Co, 5kg Mn, 6kg of Li and 39kg of Ni – Ni is the largest component of the standard and best performing EV battery

Reduced Cost Expenditure

Increased costs of Li and Co has manufacturers shifting towards reduction of Co and increased Ni in battery composition

Battery of Chevrolet Volt is 26% of total cost –automaker is currently looking to reduce costs by increasing Ni composition

Energy Efficiency

Ni increases energy density in the battery cathode which equates to longer distances travelled, batteries will be used more efficiently based on how consumers drive
