Winnipeg, Manitoba--(Newsfile Corp. - October 21, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ: LITM) ("Snow Lake"), a uranium exploration and development company, announces a major strategic expansion with the creation of Kadmos Energy Services LLC ("Kadmos"), a new U.S. based nuclear energy company dedicated to the design and deployment of small modular reactors ("SMRs"), with an initial focus on light water reactors.

Led by Dr. Youssef Ballout — a distinguished nuclear technology expert and recognized leader in reactor innovation — Kadmos positions Snow Lake at the forefront of the nuclear energy resurgence driving the global clean energy revolution. Drawing on decades of leadership advancing U.S. reactor programs, Dr. Ballout brings unmatched expertise in the design, testing, and deployment of advanced reactor systems. His career spans teaching at the Virginia Military Institute, a 26-year tenure with the U.S. Naval Reactor Program supporting submarine, carrier, and spacecraft reactor design, and senior leadership at the Idaho National Laboratory, where he directed reactor systems design and analysis and oversaw next-generation test reactor initiatives. This combination of technical depth, strategic vision, and proven leadership uniquely positions Dr. Ballout to lead Kadmos as Chief Executive Officer.

Highlights

• Kadmos Energy Services LLC launched to capitalize on the accelerating global demand for small modular reactor solutions

• Dr. Youssef Ballout appointed as founding CEO - a veteran reactor designer with decades of leadership in U.S nuclear programs

• Snow Lake to invest up to US$10M for a 49% ownership stake in Kadmos, securing a cornerstone position in next-generation nuclear energy

• Initial US$2M investment completed, enabling immediate commencement of engineering and reactor development programs

Strategic Expansion: From Uranium to Power Generation

The launch of Kadmos represents a transformational leap forward for Snow Lake - expanding from uranium exploration and development into nuclear power generation and technology development. This strategic step advances Snow Lake's mission to become an integrated player across the entire nuclear value chain, from uranium mining to reactor deployment.

Kadmos' near-term focus is on delivering turnkey, modular, and rapidly deployable light water reactors to serve utilities, data centers, and industrial energy users — all of whom face surging electricity demands amid the global energy transition. With nuclear energy now recognized as an essential enabler of energy security goals, Kadmos provides Snow Lake shareholders with direct leverage to one of the most scalable and investable clean energy themes of this decade.

Snow Lake's Investment in Kadmos

Snow Lake holds a 49% interest in Kadmos, and has agreed to invest up to US$10 million in Kadmos. An initial investment of US$2 million was made on the creation of Kadmos, with the remaining US$8 million to be contributed over time in either cash or shares of Snow Lake at Snow Lake's sole option and absolute discretion. The initial funding provided by Snow Lake will be used to initiate Kadmos' engineering and development activities. In exchange for a 14.5% stake in Kadmos, Exodys Energy will contribute its technical expertise to drive early engineering efforts and shape an integrated front-end and back-end fuel strategy. The remaining interest in Kadmos will be held amongst the Kadmos management group.

Kadmos CEO Remarks

"Our mission at Kadmos is clear and bold: to deliver turnkey, near-term deployable nuclear power plant solutions that are reliable, cost-competitive, and fully integrated with proven fuel and component supply chains," said Dr. Youssef Ballout, CEO of Kadmos.

"Throughout my career in nuclear reactor technology, I have bridged cutting-edge design with real-world deployment where there is no margin for error. At Kadmos, we are bringing that same discipline and rigor to build nuclear power plants that meet the energy demands of utilities, data centers, and industrial customers—with the technical practicality, safety, and performance they require.

Our leadership team is unwavering in its commitment to deliver reactors of the highest technical quality and safety, engineered to provide predictable, long-term power solutions for critical infrastructure and commercial operations.

Kadmos will disclose additional details in the coming weeks, including key staffing appointments, strategic partnerships, and milestone achievements for its first reactor project."

Snow Lake CEO Remarks

"This is a pivotal moment for Snow Lake and our shareholders," said Frank Wheatley, CEO of Snow Lake. "By launching Kadmos together with Dr. Ballout, we are moving decisively up the nuclear value chain - from looking to supply U.S. mined uranium, to helping power the world with clean, dependable nuclear energy.

Dr. Ballout brings unmatched expertise from a long career with the Naval Nuclear Laboratory supporting the U.S. Nuclear Navy and the Idaho National Laboratory. Kadmos is positioned to accelerate the development of practical, client-focused nuclear plants that can be delivered on schedule and at scale. By working with proven supply chain partners, Kadmos will bring credibility and execution to the next generation of nuclear power.

This is a powerful strategic and financial step forward for Snow Lake as we continue building a vertically integrated nuclear energy company."

Kadmos Aligns with U.S. Administration Policies on Nuclear Energy

Kadmos' strategy aligns with the U.S. Administration policies on expansion of U.S. nuclear energy capacity, by focusing on rapid deployment of modern reactors that leverage established reactor design know-how, supply chains and operational experience. The U.S. Administration policies provide significant tailwinds to the U.S. nuclear industry through a series of executive orders designed to:

• Accelerate the deployment of nuclear energy in the U.S.

• Deploy advanced nuclear reactor technologies, including SMRs

• Quadruple nuclear energy in the U.S. by 2050

• Reinvigorate the nuclear industrial base, including uranium mining and enrichment
