Ivanhoe Electric Confirms East Ridge Discovery at Santa Cruz Copper Project in Arizona

East Ridge Exploration Area Typhoon™ Anomaly to be Explored Further

High-Grade Copper Assays Received from Infill Drilling at Santa Cruz Deposit Area

Santa Cruz Infill Drill Hole SCC-084 Intersects 314 Meters Grading 1.06% Copper, Including 144 Meters of 1.38% Copper, 76 Meters of 1.86% Copper and 14 Meters at 2.41% Copper

NEW YORK, NY / ACCESSWIRE / November 8, 2022 / Ivanhoe Electric (NYSE American:IE)(TSX:IE) Chairman and Chief Executive Officer Robert Friedland is pleased to announce the discovery of the East Ridge oxide copper zone at the Santa Cruz Copper Project, located west of Casa Grande, Arizona. These exploration results have demonstrated the effectiveness of Ivanhoe Electric's proprietary Typhoon™ surveying system for identifying hidden copper deposits in the American Southwest. In addition, we are beginning to receive high-grade copper assay results from the extensive drilling campaign in the Santa Cruz Deposit area. These results will be incorporated into the updated Mineral Resource Estimate for the Santa Cruz Project expected in January 2023.

Mr. Friedland commented: "The discovery of copper mineralization at East Ridge is exciting in that it appears to be open for expansion in all directions. This area, identified by our Typhoon™ surveying system, and backed by detailed geological analysis, has proven the effectiveness of our ability to discover new copper deposits in areas hidden under gravel cover within the Basin and Range Province of the Western United States."

"In addition, the results from our drill campaign at Santa Cruz have confirmed the spectacular grade of the known Santa Cruz Deposit. With the steady pace of new information being received from our work at Santa Cruz, we are increasing our understanding of this enriched copper deposit. Using our Typhoon™ technology, and now with the knowledge of the Santa Cruz ‘fingerprint', we are encouraged by the prospect of additional copper discoveries in the area."

Graham Boyd, Vice President of U.S. Projects, commented: "Drilling at East Ridge has returned impressive oxide copper mineralization in our first step-out exploration holes. In particular, hole SCC-105 has returned strong visual results, intersecting over 100 meters of consistent copper oxides. Further, at the Santa Cruz Deposit area, the assays received for infill hole SCC-084 have demonstrated a broad zone of soluble oxide copper in exotic, oxide and chalcocite mineralization. These results suggest that we have only begun to uncover the potential of this district."

Atacamite is a deep green, leachable copper-chloride mineral which is 60% copper by weight. Chrysocolla is a bright blue, leachable copper oxide mineral which is approximately 30% copper by weight. Chalcanthite is a dark blue, leachable copper-sulfate mineral which is approximately 25% copper by weight. These leachable minerals are amenable to a solvent extraction/electrowinning ("SX/EW") process allowing for direct copper cathode production.

Step-out exploration drilling at East Ridge confirms discovery by Typhoon^TM

As previously announced on September 15^th, 2022, our proprietary Typhoon™ technology identified multiple large-scale anomalies at the Santa Cruz Copper Project. In addition to the significant chargeability anomaly identified by Typhoon™, the East Ridge exploration area displayed abundant geological evidence, including hints of copper mineralization in widely spaced historic drill holes.

The initial exploration results from East Ridge are promising and appear to confirm exactly what Typhoon^TM had indicated, which is that additional sulfide bodies exist and appear to be associated with new zones of enriched soluble copper mineralization. Additionally, the East Ridge discovery area is only 300 meters from the Santa Cruz Deposit, indicating the potential for nearby additions to the resource.

The Texaco Ridge Exploration Area

Texaco Ridge is part of the greater Texaco exploration target, located approximately 3 kilometers northeast of the Santa Cruz Deposit. Ivanhoe Electric previously disclosed drill hole SCC-019 on the Southern margin of the Texaco exploration target, which intersected 73 meters of 2.21% total copper (refer to the Santa Cruz Technical Report dated June 7, 2022). Typhoon^TM has identified a large zone of chargeable material in a shallower "ridge" environment in the subsurface basement topography. This area has been very sparsely drilled and is another area with the potential for the discovery of additional enriched copper mineralization. We plan to start drilling in this area in the near future.

Santa Cruz drill program

The Santa Cruz drill program currently consists of six diamond drill rigs from Major Drilling America of Salt Lake City, Utah. Cutting and sampling efforts are currently averaging approximately 250 meters per day, and there are currently 7,200 meters of drill core at both Skyline Assayers & Laboratories of Tucson, Arizona and Société Générale de Surveillance SA ("SGS") of Vancouver, British Columbia, Canada.

We expect a steady return of assay results from both labs currently processing samples for the Santa Cruz Copper Project drill core over the next several weeks.

(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 are calculated using a 0.39% total copper cut-off grade and allowing up to a maximum of 6-meters of material less than 0.39% 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

*SCC-022A is a wedged hole from parent hole SCC-022

*SCC-052 is pending complete assays

*Reported intervals for SCC-084 are calculated using a 0.39% total copper cut-off grade and allowing up to a maximum of 12-meters of material less than 0.39% total copper

These results demonstrate significant copper grades over continuous intervals of enriched mineralization, both contained within the current underground mineral resource blocks and outside the resource area. These results will be incorporated into the updated mineral resource estimate expected in January 2023.

Additional underexplored areas exist at Santa Cruz with the potential for the discovery of new copper zones

Ivanhoe Electric is currently drilling an area known as the "Newmont Parcel" (see figure below). This is an 80-acre parcel immediately contiguous to both the highest-grade zones of the Santa Cruz Deposit and the East Ridge discovery.

The "Newmont Parcel" was not drilled by previous operators during any of the major exploration campaigns completed by David Lowell (Hanna-Getty of Cleveland, Ohio and East Meadow, New York, respectively) or ASARCO of Tucson, Arizona in the 1970s. This specific parcel of land was owned by Newmont Corporation of Denver, Colorado at the time, but Newmont never drilled the area. The parcel subsequently was consolidated by previous project owners, but was also never drilled. It now forms part of our 100%-owned interests, and is an important exploration area.

Ivanhoe Electric has drilled three holes on the "Newmont Parcel", SCC-008 and SCC-011 (refer to the Santa Cruz Technical Report dated June 7, 2022) and SCC-105 (see above). All three holes have intersected significant zones of oxide copper mineralization that remain open in all directions.

As previously described, SCC-105 demonstrates that the East Ridge discovery is open in multiple directions for expansion.

SCC-005, which intersected 57 meters grading 3.52% copper (2.77% total soluble copper) at a downhole depth of 636 meters (refer to the Santa Cruz Technical Report dated June 7, 2022), was collared just 60 meters from the western boundary of the Newmont Parcel, and mineralization remains open into the Parcel area.

SCC-099 is currently being drilled on the western boundary of the "Newmont Parcel".
