Recent Infill Drilling at Ivanhoe Electric’s Santa Cruz Copper Project in Arizona Identifies New High-Grade Soluble Copper Mineralization and Continues to Validate Mineral Resource Model

Infill Drill Hole SCC-057 Intersected 78.0 Meters Grading 1.97% Copper, Including 50.8 Meters Grading 2.60% Copper

Santa Cruz Initial Assessment Remains on Schedule for Completion by End of Q3 2023

PHOENIX, AZ / ACCESSWIRE / June 14, 2023 / Ivanhoe Electric Inc. (NYSE American:IE)(TSX:IE) Executive Chairman Robert Friedland and President and Chief Executive Officer Taylor Melvin are pleased to provide an update on the drilling operations underway at the Santa Cruz Copper Project, located west of Casa Grande, Arizona. Ivanhoe Electric controls private surface land, the patented mineral rights and the associated water rights encompassing the entire Santa Cruz Project (refer to Ivanhoe Electric's May 24, 2024, news release).

Mr. Friedland commented: "Our hardworking team of women and men have been making steady progress at the Santa Cruz Copper Project, uncovering high-grade copper mineralization in areas that were previously unknown and expanding our technical knowledge in underground areas near conceptual development. We remain on track to deliver an important Initial Assessment of the Project by the end of Q3 2023. This first detailed study will provide us with valuable insights into the economic potential at Santa Cruz, moving us closer to building a modern, underground copper mine in Arizona. By doing so, we are aiming not only to support United States supply chain independence for electric metals but also create quality jobs for Arizonans."

Mr. Melvin commented: "We continue to advance our understanding of the Santa Cruz copper discovery through our extensive drilling program. Our ongoing infill and geotechnical drilling have provided us with important information about the geologic features that control high-grade copper mineralization and rock mechanics. This knowledge plays a vital role in the preparation of our Initial Assessment. Our Q3 activities will include large-diameter pump tests that will further support our understanding of the hydrogeology of the Santa Cruz Project. With the continued success of our drilling campaigns, the completion of our large surface land acquisition in May and the continued advancement of our Initial Assessment, we are excited about the future at Santa Cruz."

Infill Drilling Continues to Support the Current Mineral Resource Model

The infill and development drilling program continues to characterize key geotechnical, hydrogeological and metallurgical characteristics of the Santa Cruz Deposit. Multi-purpose infill and development drill holes, not previously included in the December 31, 2022, Mineral Resource Estimate, have intersected high-grade copper oxide and chalcocite mineralization, some in areas where copper mineralization was previously undefined.

Drill hole SCC-125 targeted definition and expansion of the high-grade Exotic Copper Domain in the current Mineral Resource Estimate and intersected visible atacamite, chrysocolla, and chalcocite mineralization starting at a downhole depth of approximately 586 meters.

Drill hole SCC-136, located in the northwestern region of the Santa Cruz Deposit, targeted a mineralized and resource controlling fault, but also intersected visible copper oxide and chalcocite mineralization starting at a downhole depth of approximately 432 meters in an area undefined by previous drilling.

These recent intersections continue to demonstrate and provide valuable insights into the extent and consistency of the mineral resource and areas for potential additions. The assay results for drill holes SCC-125 and SCC-136 are pending.

Exploration and Step-out Drilling Supports the Texaco Ridge Exploration Area for Potential Expansion

Texaco Ridge Exploration Area was previously identified by Ivanhoe Electric's proprietary Typhoon™ 3D Induced Polarization Survey (refer to Ivanhoe Electric's September 15, 2022, news release). Exploration drilling at Texaco Ridge has methodically stepped out from mineralization intersected in drill hole SCC-122 (refer to the map below).

Drill holes SCC-129 and SCC-133, located approximately 200 meters to the southeast and northeast of drill hole SCC-122, respectively, intersected visible copper oxide, chalcocite and chalcopyrite mineralization. These observations support geologically consistent mineralization between these drill holes and the Texaco Mineral Resource located to the northeast. Both the Texaco Ridge Exploration Area and Texaco Deposit remain open for expansion in multiple directions, and exploration drilling will continue to leverage our proprietary Typhoon™-generated datasets for efficient targeting. Assay results from recent drilling at Texaco Ridge are pending.

Highlighted drill intercepts not previously disclosed from the Santa Cruz Project Area (Assays for drill holes SCC-122, SCC-125, SCC-129, SCC-133 and SCC-136 mentioned above are pending. Refer to the Santa Cruz Drill Results page on Ivanhoe Electric's website for complete details of all reported drill holes.).

*Total Soluble Copper is the calculated summation of all soluble copper derived from the sequential copper analysis suite.
*Reported intervals at the Santa Cruz Deposit are calculated at a cut-off grade of 0.70% total copper.
*Results are core intervals and may not be true widths but are believed to be representative of actual drill thicknesses.
*Some rounding errors may occur.

The Santa Cruz Initial Assessment Will Outline the Potential for a High-Grade, Modern, Underground Copper Mine Situated Entirely on Private Land in Arizona

The Initial Assessment for the Santa Cruz Project is evaluating the potential for a high-grade modern underground copper mining operation which will focus on minimizing the surface footprint of the mine while at the same time incorporating leading technologies to improve efficiencies and costs. The technologies being evaluated in the Initial Assessment include the use of electric mining fleet vehicles, various renewable energy sources supported by leading-edge battery storage, and modern, efficient material handling technologies.

Ivanhoe Electric is designing a modern, responsible mine that is less reliant on carbon dioxide-emitting fossil fuels and old technologies in its operation, all to further its goal of eventually producing a cathode copper product with much lower carbon dioxide emissions per pound than a more conventional mine run entirely on fossil fuels using decades old conventional mining equipment and technologies. Minimizing the surface footprint is intended to reduce the overall environmental impact of the Santa Cruz project and limit surface-level disruptions and visual impact on the surrounding area.

The Santa Cruz Initial Assessment remains on schedule for completion by the end of Q3 2023.
