First Atlantic Nickel Confirms 30 km Trend at Atlantic Nickel Project and Begins 2024 Exploration Program Following Closing of ~$2.1M Strategic Lead Financing

First Atlantic Nickel Corp. (TSXV: FAN) (OTCQB: FANCF) (FSE: P21) ("First Atlantic" or the "Company"), is pleased to report its initial sampling has confirmed the presence of a significant 30 km nickel trend at its 100% owned Atlantic Nickel Project in central Newfoundland, Canada (the “Atlantic Nickel Project” or the “Project”). Strategically located near the Atlantic Ocean, the Project offers ideal access to maritime shipping routes, positioning it to supply nickel input for the steel and electric vehicle supply chains in both the United States and Canada. The Project's proximity to critical infrastructure, including road access, clean hydro-electric grid power, and favorable terrain and climate make it an optimal location for mining exploration and development. First Atlantic is prioritizing the identification of the strongest mineralized zones of awaruite, a naturally occurring nickel-iron alloy, with four initial and promising areas targeted for follow-up work this summer. A large corporate strategic investor has led a ~$2.1 million investment in the Company, which will expedite exploration efforts, including mapping, geophysical surveys and sampling in advance of a planned and fully funded 5000 meter drilling program, set to commence immediately.

Highlights

• Initial sampling confirms significant nickel mineralization along a 30 km trend, suggesting the potential for a large nickel district centered on the Atlantic Nickel Project.
• Awaruite (nickel-iron alloy) has been visually identified in multiple zones disseminated within widespread serpentinization of ultramafic rocks.
• New Big Gulp nickel occurrence identified (see Figure 1) in Gulp Pond area with visually identified awaruite.
• Presence of high nickel content and low sulfur values, which is optimal for awaruite nickel formation.
• Initial assays returning up to 2,800 ppm nickel from outcrops sampled over an 18 km strike length within a larger trend verify the historic results which outline a 30 km district scale nickel trend.
• Results guide the 2024 exploration and are part of the drill targeting strategy, advised by world-renowned nickel expert Dr. Ron Britten.
• Ideal location: road access, nearby hydroelectric power, favorable terrain and climate for year-round exploration.

First Atlantic has identified four priority areas - Atlantic Lake, Gulp Pond, Pipestone, and Chrome Pond - for immediate follow-up based on the recently announced compilation and initial sampling program. The Company's 2024 exploration program is set to commence immediately, focusing on these targets to further define the extent and grade of awaruite nickel mineralization along the 30 km trend. The additional data will offer a deeper understanding of the nickel mineralization and assist in accurately targeting the drill program.

Exploration is focused on alteration (serpentinization), a process responsible for forming the silvery-white nickel-iron alloy “awaruite” a magnetically recoverable nickel mineral. Field observations identified widespread serpentinization concentrated in large regional zones.

"The initial sampling at our district-scale Atlantic Nickel Project, which covers a 30 km trend with discovery potential for multiple deposits, has exceeded our expectations, revealing extensive nickel mineralization throughout this large area. These results not only validate historical data but also provide new insights for targeting our fully-funded 2024 exploration program. With Dr. Ron Britten's expertise guiding our efforts, we are well-positioned to unlock the full potential of this important nickel district in Atlantic Canada. Our vision is to leverage the district-scale nature of this project through a swift, systematic exploration approach, similar to Canada Nickel and FPX Nickel, potentially accelerating our path towards defining a significant resource through drilling," commented Adrian Smith, CEO of First Atlantic.

The initial samples summarized in Table 1 reveal consistently high nickel values that align with historic results from the sampled areas, confirming the data obtained through the Company's compilation program. The rock samples' high nickel and low sulfur content confirm the Atlantic Nickel Project as an optimal environment for awaruite nickel formation. This unique characteristic presents the potential for producing high-grade nickel concentrates without sulfur eliminating the need for downstream smelting processes. This has the potential to reduce dependence on foreign countries that currently control a significant portion of global nickel smelting capacity, and could mitigate the risk of acid mine drainage. Such a development could contribute to more secure and localized nickel supply chains while positioning the Project as environmentally favorable compared to traditional sulfide deposits.

Dr. Ron Britten, technical advisor to First Atlantic, commented, “Local evidence of multiple structural and serpentinization events, along with at least two phases of awaruite nickel formation are encouraging signs for the advancement of the Atlantic Nickel Project. The extensive Pipestone ultramafic belt measuring up to 2 km wide and ~30 km long will require additional systematic mapping and rock sampling to test the full potential. Samples will be analyzed for magnetically recovered nickel to prioritize drill targets with the best potential to host awaruite mineralization planned to be tested this year.”

Exploration Model

Awaruite nickel mineralization and serpentinization at the Atlantic Nickel project appears to be related to large-scale faulting from the eastward thrusting of the Pipestone ophiolite complex onto land during the closure of an ancient ocean basin. This tectonic process increased permeability and as a result may be a controlling factor for serpentinization of the ultramafic rocks, where the primary minerals are altered to form awaruite along with serpentine minerals, including brucite. Scientific research outlines this process as a specific chemical reaction that occurs during serpentinization of low-sulfur ultramafic rocks, forming magnetite and awaruite nickel, a silvery-white highly magnetic and ductile nickel-iron alloy. The extensive 30 km trend of these ultramafics and large scale fault structures result in widespread areas of serpentinization and awaruite formation, exploration is planned to focus on the best areas with the most abundant concentrations of disseminated awaruite formation.

The geological model is comparable to the Baptiste deposit in British Columbia, Canada in size and intensity of magnetic signature, rock types, alteration and awaruite mineralization. The Baptiste Deposit contains over 10 billion lbs1 of nickel and has attracted strategic partners, including Toyota, Outokumpu, Sumitomo Mining, and JOGMEC. The initial resource at Baptiste was completed with just 12,565 meters of drilling, demonstrating the rapid advancement potential of this deposit type.

The Company is eager to start its 2024 exploration program and will provide updates as the work progresses.
