ABOUT NORTH SHORE

The nuclear power industry is in growth mode as more nuclear power will be required to meet the world’s

ambitious CO2 emission-reduction goals and the needs of new power-intensive technologies like AI. In this

environment, new discoveries of economic uranium deposits will be very valuable, especially in established

uranium-producing jurisdictions like Saskatchewan and Ne w Mexico. North Shore is well -positioned to

become a major force in exploration for economic uranium deposits. The Company is working to achieve

this goal by exploring Rio Puerco in the Grants Uranium District of New Mexico and its Falcon and West

Bear properties at the eastern margin of the Athabasca Basin in Saskatchewan. In addition, the Company

continues to evaluate quality opportunities in the United States and Canada to complement its portfolio of

uranium properties.
