Calgary, Alberta--(Newsfile Corp. - May 18, 2021) - Fathom Nickel Inc. (CSE: FNI) (the "Company" or "Fathom"), today announced that it obtained final receipt for its non-offering prospectus on May 13, 2021.

"The Fathom team is very excited to achieve this significant milestone. Our recently completed go-public financing positions the Company to aggressively advance the exploration program at our Albert Lake Project. By completing a direct listing onto the CSE we are entering the public markets in an efficient manner that both positions Fathom as a very well funded junior explorer and preserves value for our shareholders," commented Brad Van Den Bussche, President & CEO. "We would also like to take this opportunity to thank our shareholders for their continued support and trust in our ability to execute on our vision. Fathom's advancement from a privately held company to a publicly-traded company on the CSE represents the next chapter of our growth, and we are excited about the opportunities ahead of us," he added.

In connection with the Company's direct listing on the CSE, the Company raised gross proceeds of $11,150,000 (the "Offering") through an upsized, private placement financing of flow-through special warrants (the "FT Special Warrants") and non flow-through special warrants of the Company (the "NFT Special Warrants"). On May 20, 2021, the FT Special Warrants and NFT Special Warrants will be automatically exercised, and holders of the FT Special Warrants will be issued one Common Share of the Company for each FT Special Warrant held and holders of the NFT Special Warrants will be issued a unit of the Company consisting of one Common Share of the Company and one-half of one Common Share purchase warrant ("Purchase Warrant") for each NFT Special Warrant held. Each whole Purchase Warrant entitles the holder thereof to acquire one Common Share at an exercise price of $1.00 until March 15, 2023.

Albert Lake Project Update

Since the beginning of 2021 Fathom has successfully achieved several milestones in advancing the exploration program at its Albert Lake project in north-central Saskatchewan (the "Albert Lake Project").

1. Increased Land Package of Highly Prospective Land Around the Historic Rottenstone Mine
   Fathom has staked an additional 55,732 Ha of mineral claims at the Albert Lake Project (previously named the Rottenstone Project), bringing the total exploration land package to over 90,127 Ha. The increased land package provides the Company with over 80,000 Ha of relatively unexplored potential within the same geological trend which hosted the historic Rottenstone Mine. Its exploration permit has also been expanded to include these newly acquired lands.

2. Completion of the Q1 2021 Exploration Program
   The Company recently completed its Q1 2021 Exploration Program consisting of nine drill holes for 1,232 meters drilled (the "Q1 2021 Drill Program"). The Q1 2021 Drill Program consisted of drill holes designed to extend known Rottenstone-like mineralization south of the historic Rottenstone mine. Drilling also tested the continuation to depth and along strike Rottenstone-like mineralization at the Island Showing approximately 600m north-northwest of the historic Rottenstone mine, and to test the continuation of an off-hole BHEM anomaly occurring in Rottenstone-like host rock 400m west of the historic mine. Results from the Q1 2021 Drill Program are expected to be announced within the coming weeks.

3. Full Platinum Group Element ("PGE") Analyses on Select 2021 Drill holes and 2017 Bulk Sample
   The historic Rottenstone mine produced very significant palladium and platinum credits. Fathom recognizes the historical Rottenstone deposit also contained significant amounts of rhodium, osmium, ruthenium and iridium. Full suite PGE analyses has been performed on some Q1 2021 drill holes, as well as on samples of coarse reject material of Rottenstone mineralization originally submitted by Fathom in 2017 for a preliminary metallurgical study. Results are expected in the coming weeks.

4. Gradient MAG Survey Over the Property
   Fathom secured the services of BECI exploration consulting and has completed a property-wide, high resolution, 9,595 line-km heliborne gradient MAG survey. Results are in hand and Fathom, with support of its geophysical consultants is interpreting the data and formulating target areas for 2021 ground follow-up.

5. Extensive 2021 Exploration Program Planned
   Commencing June 2021, Fathom will initiate additional exploration at the Albert Lake Property. The program will consist of mapping, prospecting and soil geochemistry in areas where the Company has thus far defined through compilation of historic data and recent BHEM data compilation, areas to host other Rottenstone-like deposits. In addition, high priority areas for follow-up exploration will come from interpretation of the recently completed heliborne gradient MAG survey. The program will last into the fall with diamond drilling anticipated to commence in late August/early September.

The Company is well funded to carry out its planned exploration programs at Albert Lake through the end of 2022 under its current plans. Ian Fraser, VP Exploration, stated, "Fathom will be enhancing its geologic model and focusing exploration on the discovery of additional deposits with Rottenstone-type mineralization throughout its extensive land package. In addition, we will be extending areas of known mineralization working towards defining a resource base."
