CEO.CA Chairman's Briefing

Prospecting highlights include:

• An outcrop grab sample returned 2.68 g/t Au within an anomalous gold zone approximately 14km along strike of the Ramp Metals Inc. Ranger gold discovery (Figures 1 & 2).
• In addition to the gold results, 13 outcrop grab samples are classified as anomalous in Mg-Cr-Ni-Co,, suggesting the presence of mafic-ultramafic intrusives and possible magmatic nickel sulphide mineralization also occurring within the area.
• Assay results with up to 9.34% Mg, up to 622ppm Cr, up to 298ppm Ni and up to 59ppm Co are considered anomalous and indicative of mafic to ultramafic composition.
• A total of 144 rock grab samples were submitted for analysis.

Calgary, Alberta--(Newsfile Corp. - September 24, 2024) - Fathom Nickel Inc. (CSE: FNI) (FSE: 6Q5) (OTCQB: FNICF) (the "Company" or "Fathom") is pleased to announce the results from a brief summer prospecting program at the Company's 100% owned Albert Lake Property.

On June 17, Ramp Metals Inc. ("Ramp") announced a significant gold discovery of 73.55 g/t Au over 7.5 meters at its Rottenstone SW Project, located within 5 km of the Albert Lake Property boundary. In response, and after reviewing Fathom airborne data at Albert Lake, the Company initiated a reconnaissance surface sampling program to test possible targets along strike of the Ramp discovery drillhole. A four-person crew prospected a select area in the southeast corner of the Albert Lake Property from August 6-12, 2024 (Figures 1 &2). The area of interest is near to the southern boundary of the Albert Lake Property, and along strike of the Ramp Metals Ranger gold discovery. Two distinct northeast trending zones of anomalous gold resulted from the prospecting exercise along with occurrences of mafic-ultramafic rocks of similar northeast trend, and locally coincide with anomalous gold samples (Figure 2). Fathom has an exploration permit in place to allow for continued exploration within this area and throughout the 90,000+ hectare Albert Lake Property through to November 2026.

Ian Fraser, CEO and VP Exploration stated, "Upon the announcement of the Ranger gold discovery by our neighbour Ramp, we were immediately intrigued by the possibility of gold mineralization continuing along strike onto our property. Our 2022 heliborne MAG survey highlighted very good structural complexity at the southern end of the Albert Lake Property and it certainly now appears there is gold plus mafic-ultramafic intrusives associated with this structural complexity. These results, while preliminary, are very encouraging. It makes us think, what else is going on within the very expansive 90,000+ hectare Albert Lake Property? With our exploration permit and camp in place, we are in a very good position to explore these possibilities."

Future Exploration Plan

Based on the exciting discovery of 2.68 g/t Au within anomalous gold showings in the southern area of the Albert Lake Property, management is planning on follow-up field exploration and, ultimately, drilling focussed on this gold potential. It is expected that these plans will take shape in the coming months.

Mr. Fraser added, "We are ecstatic with the discovery of gold showings along trend with Ramp's Ranger drillhole, in an area at Albert Lake that has seen very limited exploration. We look forward to performing follow-up exploratory work in 2025. While this exciting news does provide Fathom with a new opportunity, we very much intend to continue our focus around our emerging high-grade nickel camps at both our Albert Lake and Gochager Lake properties."

Quality Assurance / Quality Control (QA/QC) Disclosure Statement

The Company contracted the services of TerraLogic Exploration Inc. ("TerraLogic") to conduct the prospecting program at the Albert Lake property. Prospecting crews were instructed to collect rock, grab samples to provide a broad geochemical data base for the purpose of determining the potential for gold and mafic-ultramafic hosted magmatic nickel sulphides. The prospecting crews from a base fly camp set out on organized traverses and collected a representative grab sample from each outcrop encountered along the traverse. At each outcrop location (geostation) crews collected and recorded metadata associated with the location. Once sorted and logged all rock samples were shipped to ALS Canada Ltd. ("ALS") in North Vancouver, British Columbia. At ALS, individual samples were crushed to 70% <2mm and then riffle split off 250g which was then pulverized to >85% passing 75um. Analysis was by 34-element four acid ICP-AES (ME-ICP61), Au 30g FA-AA finish (Au-AA23), and select check assays by Au 50g FA-AA finish (Au-AA24). ALS is an ISO / IEC 17025 certified laboratory and independent of Fathom.

The Company's QAQC approach to the rock samples collected compares to the Company's drill core approach; that is, with respect to the insertion of blanks and standards. Two standards and 3 blank standards were inserted into the batch of 144 rock samples.

Qualified Person and Data Verification

Ian Fraser, P.Geo., CEO, VP Exploration and a Director of the Company and the "qualified person" as such term is defined by National Instrument 43-101, has verified the data disclosed in this news release, and has otherwise reviewed and approved the technical information in this news release on behalf of the Company.

About Fathom Nickel Inc.

Fathom is an exploration company that is targeting magmatic nickel sulphide discoveries to support the rapidly growing global electric vehicle market and to secure the supply of North American Critical Minerals.

The Company now has a portfolio of three high-quality exploration projects located in the prolific Trans Hudson Corridor in Saskatchewan: 1) the Albert Lake Project, a 90,000+ hectare project that was host to the historic and past producing Rottenstone Mine¹ (produced 28,724 tons @3.3% Ni, 1.8% Cu, 9.63 g/t 3E (Pd-Pt+Au) 1965-1969), and 2) the 22,000+ hectare Gochager Lake Project that is host to a historic, NI43-101 non-compliant open pit resource consisting of 4.3M tons at 0.295% Ni and 0.081% Cu², and 3) the 10,000+ hectare Friesen Lake Project located 40km southwest of the historic Rottenstone Mine and 30km northwest of the historic Gochager Lake deposit.

1 - The Saskatchewan Mineral Deposit Index (SMDI #0958) reports the production grades noted above from a small open pit. Fathom cannot confirm the production numbers nor a historic resource estimate that may have been in place ahead of production. The historic pit exists, and the Company trusts the production, as noted in SMDI #0958, to be accurate. The Company has performed test assaying of Rottenstone-type mineralization and results are consistent with production grades.

2 - The Saskatchewan Mineral Deposit Index (SMDI #0880) reports drill indicated reserves at the historic Gochager Lake Deposit of 4,262,400 tons grading 0.295% Ni and 0.081% Cu mineable by open pit. Fathom cannot confirm the resource estimate, nor the parameters and methods used to prepare the reserve estimate. The estimate is not considered NI43-101 compliant and further work is required to verify this historical drill indicated reserve.
