First Atlantic Nickel Corp. (TSXV: FAN) (OTCQB: FANCF) (FSE: P21) ("First Atlantic" or the "Company") is pleased to announce its participation at the Benchmark Mineral Intelligence GIGA USA 2025 conference, taking place June 3-4, 2025, in Washington, DC. The Company will participate in strategic meetings during this critical mineral conference to demonstrate how its Atlantic Nickel Project addresses the growing need for nickel mining that can be completely processed in North America. The Atlantic Nickel Project contains nickel in the form of awaruite, a naturally occurring, sulfur-free, highly magnetic mineral with approximately 75% nickel content. These unique properties enable direct processing through magnetic separation and flotation, eliminating reliance on foreign overseas smelting or roasting operations. This simplified mineral processing method significantly lowers energy requirements and reduces environmental impacts, strengthening the development of a resilient, domestic critical minerals supply chain.

The GIGA USA conference brings together key players from across the critical minerals sector for two days of networking, dealmaking, and policy discussions. Attendees include major automakers such as Tesla, Ford, General Motors, Rivian, Mercedes-Benz, and Volkswagen; battery manufacturers like LG Energy Solutions, Samsung SDI, and Panasonic Energy; and global mining companies including Rio Tinto, Vale, Glencore, South32, and Anglo American. Government representatives from the U.S. Department of Energy, U.S. Department of Commerce, U.S. Department of Defense, U.S. Department of State, the Government of Quebec, the Embassy of Canada, and the Delegation of the European Union will also attend. Conference topics will address the expansion of the United States' lithium-ion battery gigafactory industry and the need to establish secure, sustainable supply chains for critical raw materials, including lithium, nickel, graphite, cobalt, manganese and rare earth elements.

The conference addresses key areas of focus including strengthening the U.S. critical minerals supply chain through domestic production and expanded gigafactory capacity, examining policy and trade impacts, such as the Inflation Reduction Act (IRA), and enhancing national security through critical mineral independence. The conference will also focus on investment and financing opportunities for next-generation mining projects, innovations in battery technology and sustainability, and the importance of global collaboration and strategic partnerships.

The Company's Atlantic Nickel Project offers a secure and reliable solution for domestic nickel production. By leveraging awaruite's sulfur-free composition, high nickel content and magnetic properties, the project enables simple processing through magnetic separation and flotation without the need for secondary processing such as smelting or roasting. Unlike traditional nickel sulfide and laterite projects that undergo energy-intensive processes creating harmful waste and emissions, awaruite's metallurgical properties enable complete domestic nickel production while eliminating reliance on overseas processing. The lower energy requirements and sulfur-free nature of awaruite result in a reduced carbon and environmental footprint. The Company remains committed to strengthening North American critical minerals supply chains, with the Atlantic Nickel Project positioned to provide a secure, reliable nickel source for North American industries including electric vehicles, batteries, defense, and stainless steel manufacturing.

Awaruite (Nickel-iron alloy Ni₂Fe, Ni₃Fe)

Awaruite, a naturally occurring sulfur-free nickel-iron alloy composed of Ni₃Fe or Ni₂Fe with approximately ~75% nickel content, offers a proven and environmentally safe solution to enhance the resilience and security of North America's domestic critical minerals supply chain. Unlike conventional nickel sources, awaruite can be processed into high-grade concentrates exceeding 60% nickel content through magnetic processing and simple floatation without the need for smelting, roasting, or high-pressure acid leaching ¹ . Beginning in 2025, the US Inflation Reduction Act's (IRA) $7,500 electric vehicle (EV) tax credit mandates that eligible clean vehicles must not contain any critical minerals processed by foreign entities of concern (FEOC) ² . These entities include Russia and China, which currently dominate the global nickel smelting industry. Awaruite's smelter-free processing approach could potentially help North American electric vehicle manufacturers meet the IRA's stringent critical mineral requirements and reduce dependence on FEOCs for nickel processing.

The U.S. Geological Survey (USGS) highlighted awaruite's potential, stating, "The development of awaruite deposits in other parts of Canada may help alleviate any prolonged shortage of nickel concentrate. Awaruite, a natural iron-nickel alloy, is much easier to concentrate than pentlandite, the principal sulfide of nickel." ³ Awaruite's unique properties enable cleaner and safer processing compared to conventional sulfide and laterite nickel sources, which often involve smelting, roasting, or high-pressure acid leaching that can release toxic sulfur dioxide, generate hazardous waste, and lead to acid mine drainage. Awaruite's simpler processing, facilitated by its amenability to magnetic processing and lack of sulfur, eliminates these harmful methods, reducing greenhouse gas emissions and risks associated with toxic chemical release, addressing concerns about the large carbon footprint and toxic emissions linked to nickel refining.

The development of awaruite resources is crucial, given China's control in the global nickel market. Chinese companies refine and smelt 68% to 80% of the world's nickel ⁴ and control an estimated 84% of Indonesia's nickel output, the largest worldwide supply ⁵ . Awaruite is a cleaner source of nickel that reduces dependence on foreign processing controlled by China, leading to a more secure and reliable supply for North America's stainless steel and electric vehicle industries.
