Phoenix, Arizona--(Newsfile Corp. - June 23, 2025) - Ivanhoe Electric Inc. (NYSE American: IE) (TSX: IE) ("Ivanhoe Electric") Executive Chairman Robert Friedland and President and Chief Executive Officer Taylor Melvin are pleased to announce the completion of the Preliminary Feasibility Study (the "Study") for the Company's Santa Cruz Copper Project in Arizona. Located in the heart of Arizona, a state known for its prolific mining history and its booming technology industry, the Santa Cruz Copper Project is poised to become one of the nation's next major domestic producers of refined copper. The highly engineered Study confirms the strong economics of a high-quality, high-grade underground copper mining operation and heap leach processing facility supported by modern technologies. The NI 43-101 Technical Report co-filed in Canada will include the Study as a Feasibility Study as defined by the Canadian Institute of Mining, Metallurgy and Petroleum.

The Preliminary Feasibility Study, as prepared under United States regulatory requirements, provides the requisite engineering studies needed to pursue long-term project financing. Project financing efforts are already underway. Ivanhoe Electric is pursuing multiple avenues of funding, including support from United States government agencies, commercial lending institutions, and potential strategic partners at the asset level. On April 15, 2025, Ivanhoe Electric received a Letter of Interest from the Export-Import Bank of the United States outlining the potential to provide up to $825 million in debt financing with a 15-year repayment tenor under the Make More in America initiative (refer to Ivanhoe Electric's April 15, 2025 news release).

Mr. Friedland commented: "Given global conflicts that concern us all, the United States is now awake to the urgent national security imperative to restore domestic American mineral production to the scale of the American economy. Our government, industry, and defense establishment clearly recognize the paramount importance of having a secure, domestic supply of all critical minerals in the 21st century, including copper. The skillsets and government support required to mine copper, the king of metals, are the same skillsets required to mine any and all elements on the periodic table. Our Santa Cruz Copper Project is at the leading edge of this resurgence - as one of the first new copper mines that will be opened in the United States in a generation…right in the heart of Arizona - "the Copper State", with its burgeoning automotive, defense, and technology industries…including the likes of Lucid Motors and Taiwan Semiconductor Manufacturing Company. A simple Google search will show anyone there are over 1,250 aerospace and defense-related companies in the state of Arizona alone.

Santa Cruz will mine the largest high-grade copper oxide orebody in America…which will be processed onsite by a new generation of skilled and highly paid American workers. Santa Cruz will produce an LME Grade A 99.99% pure copper cathode product that will be ready for immediate sale to American industry from our mine gate. Our project will not process concentrate in antiquated, expensive and polluting smelters or ship copper concentrate back and forth across international borders for downstream processing. We will produce pure American copper mined and processed in America, and directly shipped from Arizona for use in American homes, factories and our national defense industry. Santa Cruz is the right project, in the right place, at the right time. Our progress to date could not have been achieved without the support of our long-term supportive investors, such as Saudi Arabia's Maaden and BHP, the world's largest mining company, and several of the world's top institutional investors who understand the urgent need for domestic copper production. This is what the American mineral industry and resurgence must look like - clean, secure, strategic, and ready to support American national security."

Mr. Melvin commented: "I am proud of the extraordinary work by our Santa Cruz Project team to complete our Preliminary Feasibility Study on time and on budget. We have assembled a dedicated team of talented mine engineers and underground specialists who have been critical in getting us to this point. Working together with our expert industry consultants, our team's tireless efforts have resulted in a highly engineered underground mine plan and a simplified heap-leach process design with low initial capital, low unit operating costs, and high copper recoveries. Our advanced Santa Cruz Project will provide high-paying jobs in Arizona and be a significant long-term U.S. producer of copper cathode to help meet domestic demand. We are fortunate to have such a high-quality copper asset on private land with excellent infrastructure in Arizona, a state with a rich mining history and a bright mining future."

High-Grade Oxide and Chalcocite Mineral Reserves Amenable to Heap Leaching Support a 23-Year Mine Life

The Study includes an initial Mineral Reserve Estimate for the Santa Cruz Copper Project, including Probable Reserves for the Santa Cruz and East Ridge Deposits. Stope shapes were created based on mineralized zone geometry and optimized based on economic prospectivity and geotechnical parameters specific to the rock type, the orebody orientation, and the mining sequence. Recovery and dilution factors were applied to calculate the final tonnes and grade of the reserve.

Probable Reserves of 136 million tonnes at a 1.08% total copper grade, totaling 1.5 million tonnes of contained copper were calculated (Figure 5). Only high-grade copper mineralization from the Oxide and Chalcocite domains of the Santa Cruz and East Ridge Deposits, highly amenable to the heap leaching flowsheet, comprises the current Mineral Reserves.

Table 3. Santa Cruz Copper Project Mineral Reserves summary

Notes: 1. The mineral reserves in this estimate are current to June 23, 2025 and were independently prepared, including estimation and classification, by BBA USA Inc. They are reported in accordance with the definitions for mineral reserves in S-K 1300. 2. The point of reference for the estimate is the point of delivery to the process facilities. 3. The mineral reserves for the Santa Cruz and East Ridge deposits were completed using Deswik mining software. Mineral reserves are defined within stope designs that are prescribed by rock mechanics, considering the specific characteristics of deposits, mineral domains, mining methods, and the mining sequence. Transverse longhole stoping is the optimal mining method with uppers and cut & fill methods used where appropriate. Mining will occur in blocks, extracting ore from the bottom upwards, with paste backfill providing ground support to sustain a production rate of 20,000 tonnes per day for the first 15 years of operation. 4. Mineral reserves are estimated at an NSR cutoff value of $43.95/t for longhole stoping and $60/t for longitudinal retreat stopes and drift and fill. The NSR values reflect the discrete metallurgical responses for each mineral reserve block using metallurgical recoveries for heap leach of 96% for acid soluble copper, 83% for cyanide soluble copper, 22% for residual copper. Underground mineable shapes optimization parameters include a long-term copper price of US$4.00/lb. 5. Mineral reserves account for mining loss and dilution. 6. Mineral reserves are a subset of the indicated mineral resource and do not include the inferred mineral resource. 7. Rounding, as required by the guidelines, may result in apparent summation differences between tonnes, grade, and contained metal content.

Simplified Design and the Use of Modern Mining Technologies Contribute to a Faster Development Timeline, Targeting First Copper Cathode Production in 2028 and Ramp-up to Full Production From 2029

The Project's Mineral Reserves will be accessed by conventional twin decline drifts. The Study design includes the use of roadheader technology to construct the declines, measuring approximately 8 kilometers in combined length. Main intake and exhaust raises will be developed using blindbore shaft sinking to supply ventilation to the mine workings (Figure 6 and Figure 7).

The underground mine will utilize the latest mining equipment, including a tele-remote-operated electric fleet, mine telemetry, and grade control technologies. Underground mining will primarily use longhole stoping and local drift-and-fill, totaling approximately 201 kilometers of stope cuts completed across 16 main levels. Hydrogeological mitigation strategies during decline development and mining include grouting, hydrostatic lining, and silica gel injection. Groundwater modelling and mitigation result in residual passive inflow rates ranging from approximately 6,000 to 8,000 gallons per minute during peak mining periods.

Throughput will steadily increase from the start of production onward to achieve an average of 20,000 tonnes per day, producing an annual average of 72,000 tonnes of copper cathode over the first 15 years of the mine life (Figure 8).

Study Supports High-Grade Heap Leach Operation that will Produce Pure Copper Cathode for United States' Consumption

Data analysis and trade-off studies related to the extensive drilling and associated metallurgical, hydrogeological, and geotechnical studies identified the material benefits of using a conventional chloride-assisted on/off heap leaching flowsheet to produce copper cathode. A simple leaching operation reduces surface processing and ramp-up complexities while maintaining the ability to balance mine feed. Heap leaching also lowers surface initial and sustaining capital and lowers operating costs, which in turn enhances Mineral Reserves.

Mined ore will be brought to the surface and processed through a conventional chloride-assisted on/off-heap leach process to produce copper cathode through solvent extraction and electrowinning (Figure 9). The high-grade nature of the Santa Cruz and East Ridge orebodies enables high copper recoveries averaging 92.2% over the life of mine, with low sulfuric acid consumption of 6 kilograms per tonne of treated ore. Up to 50% of the spent ore will be converted into paste and used as backfill underground.

As is common in modern solvent extraction-electrowinning plants, London Metal Exchange Grade A copper production will be expected after an initial commissioning phase.

Private Land Enables Streamlined Permitting Process

The Santa Cruz Copper Project requires permits primarily from the City of Casa Grande, Pinal County, and the State of Arizona, with only one Federal permit required. Land use authorizations from the City of Casa Grande, including a General Plan Amendment and Major Amendment to a Planned Area Development Zone, have already been obtained and allow mining activities and infrastructure within the project site.

Table 4. Current Santa Cruz Copper Project permitting status and timeline

The current Santa Cruz Copper Project development plan, subject to project financing and receipt of necessary permits, targets initial construction in the first half of 2026 and first copper cathode produced in 2028 (Figure 10). The indicative development plan is an illustrative timeline, subject to permitting and project financing.

Additional Indicated Mineral Resources, Exclusive of Mineral Reserves, Provide Potential Opportunities for Future Expansion

Indicated Resources at Santa Cruz and East Ridge, exclusive of Mineral Reserves, comprise a total of 1.5 million tonnes of contained copper. Indicated Resources in mineralized domains amenable to heap leaching at Santa Cruz total 0.8 million tonnes and 41,000 tonnes at East Ridge. These Indicated Resources at Santa Cruz and East Ridge are not included in the current mine plan, and if converted to Mineral Reserves, represent near-mine expansion potential. Santa Cruz also includes Indicated Resources of 0.5 million tonnes of contained copper grading 0.73% total copper in the Primary domain. The Primary domain comprises primary copper sulfide mineralization not amenable to the heap leach flowsheet. Additional testwork and studies on the Primary domain may provide longer-term expansion potential, requiring the development of additional processing infrastructure.

Additionally, the Santa Cruz Copper Project includes Inferred Resources, which are not included in the Study or the associated mine plan, which comprise a further 3.3 million tonnes of contained copper across the Santa Cruz, East Ridge, and Texaco Deposits.

Table 5. Mineral Resource Estimate, Exclusive of Mineral Reserves Summary

Notes on mineral resources: 1. The mineral resources in this estimate were independently prepared, including estimation and classification, by BBA USA Inc., and are reported in accordance with the definition for mineral resources in S-K 1300. 2. Mineral resources that are not mineral reserves do not have demonstrated economic viability. 3. Mineral resources are reported in situ, exclusive of mineral reserves. 4. The mineral resources for Santa Cruz, East Ridge, and Texaco deposit were completed using Datamine Studio RM software. 5. The mineral resources are current at June 23, 2025. 6. Mineral resources constrained assuming underground mining methods for the Santa Cruz deposit are reported at an NSR cutoff of US$32.00 for heap leach and US$34.00 for concentrator; Texaco deposit is reported at an NSR cutoff of US$32.00 for heap leach and US$34.00 for concentrator; and East Ridge deposit is reported at an NSR cutoff of US$40.00 for longhole stoping and US$50.00 for drift and fill. The cutoff reflects the total operating costs to define reasonable prospects for economic extraction by conventional underground mining methods. Material from within mineable shape-optimized wireframes has been included in the mineral resource. Underground mineable shapes optimization parameters include a long-term copper price of US$4.00/lb,gold price of US$1,900/oz, and silver price of US$24.00/oz. Process costs of US$7.00 to US$9.00 per processed tonne; direct mining costs between US$22.00 to US$40.00 per processed tonne reflecting various mining method costs (leach, long hole or drift and fill), mining general and administration costs of US$2.63 per processed tonne, onsite processing costs between US$31.63 to US$49.63 per processed tonne, along with variable royalties between 5.01% to 6.96% NSR, and a mining recovery of 100%. 7.
