Fathom intercepts nickel-copper-cobalt zones at Gochager Lake

Calgary, Alberta--(Newsfile Corp. - June 24, 2026) - Fathom Nickel Inc. (CSE: FNI) (FSE: 6Q5) (OTCQB: FNICF) ( "Fathom", or the "Company" ) is pleased to announce that the Phase-2 drill program at Gochager Lake continues to demonstrate the effectiveness of BHEM (borehole electromagnetic surveying) targeting. Follow-up drilling of off-hole conductors identified through BHEM probes has identified two new zones of gabbro-hosted nickel-copper-cobalt 1 mineralization northeast and southwest of the historic deposit. With approximately two-thirds of the planned 3,000-meter program now complete, the Company expects drilling to conclude by June 30, with core logging and processing to be completed during the first week of July.

Phase-2 assay results are expected to be released in early August. Ian Fraser, Fathom CEO and VP Exploration, stated, "An off-hole BHEM anomaly below drillhole GL26024, tested by drillhole GL26028, has led to the discovery of a new zone of gabbro-hosted nickel-copper-cobalt mineralization approximately 100 meters northeast of the historic Gochager Lake deposit. Drillhole GL26029, drilled as a follow-up to GL24014 to test an off-hole BHEM anomaly, also intersected gabbro-hosted nickel-copper-cobalt mineralization approximately 150 meters southwest of the deposit.

This represents another new zone and the furthest southwest mineralized intercept drilled on the property to date. BHEM probes continue to identify off-hole conductivity, and follow-up drilling of these conductors has consistently intersected nickel-copper-cobalt-bearing sulphides in gabbroic to ultramafic rocks and metasedimentary rocks. The Company continues to benefit from the elimination of helicopter dependency, and this has resulted in approximately an additional 1,000 meters of drilling over and above what was originally planned and budgeted for."

The highlighted 294.2 to 301.0m interval includes semi-massive sulphide veins with pyrrhotite hosting visible pentlandite and trace chalcopyrite, within a broader zone of disseminated-interstitial, locally net-textured and stringer-style pyrrhotite with visible pentlandite.

Figure 2, Panel B: Drillhole GL26029 intersected nickel-copper-cobalt mineralization in gabbro from 193.8 to 214.4m. The highlighted 204.6 to 212.5m interval comprises coarse to fine-grained gabbro containing chalcopyrite stringers, disseminated-interstitial pyrrhotite hosting pentlandite, and semi-massive sulphide breccia veins of pyrrhotite-chalcopyrite with visible pentlandite. The nickel-copper-cobalt mineralization and host lithologies intersected in GL26028 and GL26029 are consistent with mineralization styles observed in the historic deposit.

Both drillholes contain higher densities of semi-massive to massive sulphide veins within broad zones of disseminated, blebby and stringer-style sulphide mineralization. These two zones are currently interpreted as separate from, but similar in style to, the Gochager Lake deposit. The increased vein density provides further evidence of remobilized nickel-copper-cobalt sulphides from a distinct source and supports continued exploration for high-grade massive sulphide deposits at the Gochager Lake Project.

Quality Assurance / Quality Control (QA/QC) Disclosure Statement As part of its ongoing exploration activities, Fathom is utilizing a portable Vanta™ XRF Analyzer ("pXRF") to provide real-time lithogeochemical, multi-element data on surface rock chip samples and rock grab samples collected in the field. The Vanta™ XRF Analyzer is a hand-held device, held in position for a total 120 seconds - beam 1 (30 seconds), beam 2 (60 seconds) and beam 3 (30 seconds) to allow for an effective reading of elements occurring at that specific point, and at that specific surface of a rock or drill core sample. All elements detected at that specific point; nickel, copper, cobalt (Ni-Cu-Co) plus key pathfinder elements, chrome and magnesium (Cr-Mg), are recorded.

The reader is cautioned that pXRF data should be treated only as an indication of elements, as the accuracy of the beam position on a particular element is variable. 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 secure the supply of North American Critical Minerals and to support the global green energy transition.

The Company now has a portfolio of three high-quality exploration projects located in the prolific Trans Hudson Corridor in Saskatchewan, Canada: 1) The Albert Lake Project, a 90,000+ hectare project that hosts the historic Rottenstone Mine; 2) The 33,000+ hectare Gochager Lake Project that hosts the historic Gochager Lake deposit, 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.
