PHOENIX, AZ / ACCESSWIRE / January 8, 2024 / 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 ongoing infill and exploration drilling and technical work at the Santa Cruz Copper Project, located west of Casa Grande, Arizona.

Mr. Friedland commented: "Our extensive exploration and development drilling programs at the Santa Cruz Copper Project have yielded very strong results and continue to uncover the full potential of the project. By incorporating sustainable technologies and renewable energy into the upcoming Prefeasibility Study and leveraging cutting-edge underground material handling methods, we are advancing studies at Santa Cruz for a modern, high-grade, underground copper mine with very low projected carbon dioxide-equivalent emissions."

Mr. Melvin commented: "The fourth quarter of 2023 was an important time for the advancement of our Santa Cruz Copper Project in Arizona. We significantly increased our development drilling activity and received substantial assays from recent exploration drilling. In addition to raising our level of confidence in the Santa Cruz and East Ridge mineral resource estimates, recent infill drilling identified a large, high-grade oxide domain in the Santa Cruz deposit. This domain contains higher copper grades and is located in better quality ground conditions than previously modeled in our 2023 Initial Assessment. Our ongoing development drilling and test work will support the studies required for our Santa Cruz Prefeasibility Study, which we expect to complete before the end of Q2 2025. Beyond our development drilling at Santa Cruz and East Ridge, assays from recent step-out exploration at Texaco Ridge identified wide zones of primary sulfide mineralization that could provide future growth for our Santa Cruz Project. The combined success of our recent development and exploration drilling programs at Santa Cruz provides us with strong momentum as we enter 2024."

37 development drill holes totaling 25,176 meters have been drilled at the Santa Cruz and East Ridge Deposits since the release of the September 2023 Initial Assessment

The December 2022 Mineral Resource Estimate that formed the basis for the September 2023 Initial Assessment was modeled from 153,000 meters of drilling in 170 diamond
drill holes. Since the effective date of the 2022 Mineral Resource Estimate, Ivanhoe Electric has completed an additional 76 drill holes, totaling 55,964 meters, with 25,176 meters drilled since the September 2023 Initial Assessment.

Drilling activity at Santa Cruz ramped up in Q4 2023, with eight rigs drilling nearly 10,000 meters in November alone.

Infill and technical drilling confirm the presence of a high-grade oxide and chalcocite domain

Recent drilling at Santa Cruz has confirmed the presence of high-grade soluble copper within mineralized oracle granite in an area that was previously classified as an exotic domain within the 2022 Mineral Resource estimate. We are referring to this domain as the Verde Domain.

The Verde Domain has higher grades, better rock mass conditions and lower water flow rates compared to previous modeling. The improved ground characteristics combined with higher copper grades provide upside potential in terms of possible mining method, mining rate, and metallurgical recovery compared to what was modeled for this area in the Initial Assessment. The opportunity to mine the Verde Domain in the relatively early years is being studied; this has the potential to accelerate capital payback and boost project economics. The mineralization intersected within the Verde Domain in drill hole SCC-125 includes:

• 66 meters @ 2.85% total copper from 595 meters, including 56.75 meters @ 3.22% total copper from 598 meters
• High-grade intersections within SCC-125 include 17.05 meters @ 4.69% total copper from 602 meters and 11 meters @ 4.87% total copper from 626 meters

Figure 3. Shows Verde Domain drilling that has delineated an area of approximately 200 meters by 140 meters in plan view. Assays are pending for several holes in this domain.

Infill drilling designed to support the conversion of indicated resources to probable reserves

The Initial Assessment is based on 105.2 million tonnes of modeled mill feed from the current indicated and inferred mineral resource with an average grade 1.58% total copper. The goal of the current development drilling program is to increase the quality and confidence of the indicated mineral resource in order to convert a greater portion of resources to probable mineral reserves as part of the Prefeasibility Study. In 2023, we completed 76 drill holes in support of this conversion effort.

Exploration drilling at Texaco and Texaco Ridge provides encouraging results

The Texaco Ridge Exploration Area was identified by Ivanhoe Electric's proprietary Typhoon^™ 3D Induced Polarization Survey in September 2022. Ivanhoe Electric drilled 10 holes totaling 8,606 meters with a single rig at Texaco Ridge during the first half of 2023. The intention of this drilling was to step out into areas beyond the drilled Texaco Deposit that showed high mineralization potential based on Typhoon^™ survey results.

Hole SCC-122 at Texaco Ridge intersected broad primary sulfides with an intercept of 327 meters @ 0.81% total copper (from 564 meters), using a 0.39% total copper cut-off. This intercept includes several zones at the same 0.8% total copper cut-off grade as the nearby Texaco mineral resource:

• a chalcocite-enriched zone of 18 meters @ 1.65% total copper (from 564 meters)
• a primary sulfide zone of 28 meters @ 0.91% total copper (from 604 meters depth)
• a primary sulfide zone of 49 meters @ 0.86% total copper (from 682 meters depth)
• a primary sulfide zone of 63 meters @ 0.89% total copper (from 797 meters depth)

Step-out drilling to the southwest has intersected high-grade soluble copper that remains open. Drill hole SCC-135 includes several zones of soluble copper mineralization at the same 0.8% total copper cut-off grade as the nearby Texaco Mineral Resource:

• 12.75 meters @ 2.02% total copper (1.97% total soluble copper) from 649 meters depth
• 6.37 meters @ 2.50% total copper (2.48% total soluble copper) from 667 meters depth

Step-out drilling to the northeast, highlighted by drill hole SCC-133, has intersected a broad intercept of enriched sulfide material containing 67 meters @ 0.90% total copper (0.57% total soluble copper) from 615 meters.

SCC-122 and its step-out drill holes have demonstrated that the primary sulfide system remains open in several directions, while drill holes SCC-133 and SCC-135 show the potential for additional soluble copper mineralization. Assays for these holes are shown in Figure 3 and reported in the table below.

All Texaco Ridge drill holes lie entirely outside the December 2022 Texaco Resource boundary.

Figure 4. Cross section showing Texaco Ridge drilling and referenced highlighted intercepts below.

Exploratory drilling at the Texaco Deposit area has also demonstrated the potential expansion of the primary sulfide area. Drill hole SCC-144, drilled just outside the edge of the December 2022 Texaco mineral resource, intersected a thick intercept dominated by primary sulfides including 191.75 meters @ 0.73% total copper (from 619 meters depth) using a 0.39% total copper cut-off. This includes several intercepts at the same 0.8% cut-off grade of the nearby Texaco Resource:

• A soluble zone of 22.36 meters @ 0.92% total copper (0.88% soluble copper) from 625 meters depth
• A primary sulfide zone of 40 meters @ 1.09% total copper from 712 meters depth
• A primary sulfide zone of 13.64 meters @ 0.99% total copper from 768.80 meters depth

SCC-144's position over 300 meters southwest from SCC-019, and outside the Texaco Indicated and Inferred Resources, demonstrates the potential for new zones of high-grade primary sulfide in the Texaco Deposit area.

Santa Cruz Project Prefeasibility Study expected by end of Q2 2025

Since completing the Initial Assessment in September 2023, work on the Santa Cruz Prefeasibility Study has commenced and is ongoing. This includes infill drilling and supporting technical and trade-off studies which seek to identify opportunities to improve upon the operational and economic results of the September 2023 Initial Assessment.

In particular, we have completed several large diameter test wells to further assess and refine the hydrogeological model. We are also assessing alternative tailings technology and methodologies seeking to maximize underground tailings storage. Importantly, we are also continuing to assess various programs to support renewable energy technologies aimed at potentially providing 100% of the electricity needs for the Project.
