First Drill Targets Identified At Umm Ash Shalahih After Typhoon Survey

RIYADH, SAUDI ARABIA - Ivanhoe Electric Inc. announced the completion of the first full quarter of exploration activities in Saudi Arabia by its joint venture company established between Ivanhoe Electric and Saudi Arabian Mining Company Ma'aden.

President and Chief Executive Officer, Taylor Melvin, said, "We had an exceptional first quarter of exploration activities in Saudi Arabia with our partners at Ma'aden. Our dedicated joint team completed the first Typhoon™ survey at Umm Ash Shalahib and identified our first drill targets which we expect to start drilling by the end of May. We demonstrated the disruptive capabilities of Typhoon™ together with the machine learning-based inversion software of our subsidiary, Computational Geosciences, to rapidly identify subsurface geophysical anomalies in a challenging geologic environment. With large areas of resistive rock exposed at surface, several portions of our survey required transmission voltages of over 5,000 volts, which Typhoon™ is capable of achieving while maintaining a high signal quality. We are excited to continue our Joint Venture's exploration activities across the Al Amar and Wadi Bidah belts as we deploy a new generation of Typhoon™ units into the field."

Initial Typhoon™ survey on the Umm Ash Shalahib Exploration License near the Al Amar Gold-Copper-Zinc Mine was successfully completed and identified promising anomalies for drill testing

The Joint Venture's initial Typhoon™ survey commenced in late November 2023 and was completed in March 2024. The survey covered 76 km2 of the Umm Ash Shalahib exploration license which largely surrounds Ma'aden's Al Amar Gold-Copper-Zinc mine (which is not part of the Joint Venture).

The first high priority area is called ‘Area B', an area previously explored by France's Bureau de Recherches Géologiques et Minières (BRGM) in the 1970s. The BRGM identified several areas at surface with geological alteration and mineralization, including Area B. Our Typhoon™ survey results correlate very closely with the previous work but extend and expand the results to greater depth, providing an attractive target for follow-up drilling. Area B is an area that also features ancient artisanal vein mining for gold at surface, attesting to the presence of historical near-surface mineralization.

The second high priority area is called ‘Umm Ad Dabah', which is located to the north of the Umm Ash Shalahib exploration license at the northern limit of the recently completed survey grid. Previous mapping and drilling by the BRGM in the 1980s had identified an area showing Volcanogenic Massive Sulfide ("VMS") mineralization in their drill holes. The Typhoon™ survey results show these as both conductivity and chargeability anomalies extending to the northeast and southwest of the surface outcrop and historic drill holes. The altered zone is about 360 m long and consists of very intense epidote-chlorite-actinolite alteration with disseminated iron oxide boxworks, presumably after pyrite.Copper oxides are locally observed in fractures and rock cleavage at surface.

Drilling of these two high priority targets is expected to commence before the end of May 2024.

As the survey at Umm Ash Shalahib encompassed the Al Amar Gold-Copper-Zinc Mine site, identification of on-mine or near-mine geological targets is also a priority. As a result, a joint interpretation team has been assigned from the Al Amar mine geology team, Ma'aden, and Ivanhoe Electric to help guide this interpretation.

Typhoon™ survey work has now moved to the Al Amar Exploration License 11 which is to the immediate north of Umm Ad Dabah and was chosen because the Umm Ad Dabah geophysical anomalies trend onto this license. In addition, while initial exploration activities have focused on the Al Amar Belt, early exploration work will start in the second quarter at the ‘Gehab' prospect in the Wadi Bidah Belt area located between 220 km and 270 km southeast of Jeddah. Gehab was identified as an outcropping gossan related to the surface exposure of VMS by the BRGM in their work in the 1970s. Limited drilling was completed but was not expanded beyond the limited surface expression. Gehab is a high priority for Typhoon™ survey work once the first new generation Typhoon™ unit arrives in Saudi Arabia. Ahead of that, geological mapping and sampling work will start in the second quarter to provide geological and geochemical data for incorporation into the Typhoon™ model that will potentially provide significant down dip and strike extension of known surface mineralized exposures.

As the subsequent new generation Typhoon™ units arrive in Saudi Arabia, they will be deployed to the other high priority areas in the Al Amar Belt where satellite imagery and historical work has identified surface alteration potentially associated with mineralization.
