About Ivanhoe Electric

We are a United States-based, technology-driven minerals exploration and development company with a focus on copper and other critical metals vital to electric transmission and generation, manufacturing, infrastructure development, technology, and national security. Our wholly owned assets are located in the United States, led by our advanced-stage Santa Cruz Copper Project on private land in Arizona. We operate exploration joint ventures and alliances in Saudi Arabia with Maaden, in Chile with Sociedad Química y Minera de Chile ("SQM"), and in the United States with BHP. We use our powerful Typhoon™ geophysical surveying system, together with advanced data analytics software provided by our subsidiary, Computational Geosciences Inc. ("CGI"), to accelerate and de-risk the mineral exploration process in the search for new deposits of critical metals that may otherwise be undetectable by traditional exploration technologies. We believe the United States is significantly underexplored and has the potential to yield major new discoveries of critical metals.

We are committed to the establishment of strong relationships with our local communities and the responsible development of our projects by incorporating best practices for health, safety and environmental standards, water management, protection of local cultural heritage and biodiversity, and minimizing our environmental footprint.
