CORPORATE INVESTORS OPERATIONS KNOWLEDGE CENTER CONTACT Environment & Responsibility Sustainability Report Dear Stakeholder: Energy Fuels is proud of our record of environmental stewardship. We work hard every day to ensure our operations minimize potential impacts to the environment, including water, air, wildlife, soil, and cultural resources. We operate in strict compliance with all applicable laws and regulations, and where practicable, we strive to exceed those standards. Past uranium mining in the U.S. created many health and environmental issues. However, it is important to understand that most health and environmental impacts from the uranium industry resulted from operations that occurred decades ago in the years during and after WWII and at the height of the Cold War. Energy Fuels – and the regulators that oversee our operations – are working to ensure that those mistakes are not repeated. The uranium we responsibly produce today is helping address some of the most daunting health and environmental issues facing the world today – air pollution and climate change. We are proud to play a growing part in this global effort. Mark S. Chalmers President & CEO Energy Fuels is committed to the highest standards of corporate responsibility and environmental protection. We operate our facilities in a manner that puts the safety of our workers, contractors, communities, environment, and principals of sustainable development above all else. Whenever issues of safety conflict with other corporate objectives, safety shall be the first consideration. Energy Fuels works hard to develop relationships with the local communities in which we operate to address concerns and build support among our stakeholders. While local communities will realize the benefits of our operations through jobs, tax revenues, and economic development, they will also bear some of the burdens associated with such development. Through our culture of safety, environmental stewardship, and strict adherence to all federal, state and local laws and regulations, we are constantly working on being good corporate citizens and valuable members of the communities in which we operate. Energy Fuels requires strict adherence to our Code of Ethics, and Environment, Health & Safety Policy.
