First Drill Hole at Typhoon™ Far Southwest Anomaly Confirms Discovery of Copper at 1,059 Meters Depth

East Ridge Discovery Continues to Grow with Step-Out Drilling

NEW YORK, NY / ACCESSWIRE / November 29, 2022 / Ivanhoe Electric (NYSE American:IE) (TSX:IE) Executive Chairman Robert Friedland and President and Chief Executive Officer Taylor Melvin are pleased to provide an update on drilling operations and the remarkable discovery of copper mineralization at the Typhoon™ "Far Southwest" Anomaly, at the Santa Cruz Copper Project west of Casa Grande, Arizona.

Mr. Friedland commented: "With the terabits of information gained from our 6,500-acre proprietary Typhoon™ geophysical survey, we can leverage our exploration dollars by drilling precisely where Typhoon™ indicates we should. We continue to demonstrate the exceptional reliability of Typhoon™ data processed by Computational Geosciences Inc. - first by making the discovery of East Ridge reported on November 8^th and now by finding deep, intrusive-hosted copper mineralization at the Far Southwest Anomaly. We know of no other geophysical technology that directly detects deep chargeable copper mineralization at depths of over 3,000 feet. This American-owned technology is truly revolutionary and should be celebrated as such."

Mr. Melvin commented: "This is an exciting time for the team at Ivanhoe Electric. Our repeated exploration drilling successes at the East Ridge discovery and now at the Far Southwest Anomaly demonstrate the power of our proprietary Typhoon™ technology and provide us with excellent opportunities for near-term resource expansion. The recent visual results at East Ridge hole SCC-109 showing oxide copper mineralization further demonstrate the potential for new discovery at the Santa Cruz Copper Project."

Deep copper mineralization at Far Southwest Anomaly identified by Typhoon™ and confirmed by exploration drilling

Exploration drill hole SCC-098 was collared approximately 1,000 meters (0.62 miles) southwest of the nearest drill hole in the Santa Cruz resource area. After over 1,000 meters (3,300 feet) of basin-fill gravel cover, which obscures the underlying geology to conventional geophysical techniques, our drill hole crossed a fault and entered primary chalcopyrite and pyrite mineralization within intrusive rocks.

The intersection of these low to moderate concentrations of copper as chalcopyrite and accessory pyrite within a Laramide-age diorite porphyry with potassic alteration is an excellent technical achievement and demonstrates the utility of Typhoon™ to find new copper. We expect this zone will represent relatively low-grade "primary-style" sulfide mineralization and believe it should be viewed as strong evidence in support of delineating another faulted-off portion of the Santa Cruz mineral system. Based on our geological team's understanding of the faults and structural relationships in the Santa Cruz district, we interpret the potential for leachable copper oxides, enriched copper sulfides and primary sulfides to exist within this fault block at somewhat shallower depths. We believe this mineralization potential to be located several hundred meters to the northeast of drill hole SCC-098. This relationship of primary sulfides to the enriched and leachable copper zones is already well established at both the Santa Cruz Deposit and East Ridge and may or may not repeat at the Far Southwest Exploration Area.

Step-out drilling at East Ridge discovers additional significant oxide copper mineralization

Exploration drilling continues at the East Ridge discovery area, following the recent success of drill hole SCC-105 (reported on November 8^th). Ivanhoe Electric has discovered additional oxide copper mineralization in drill hole SCC-109, located approximately 400 meters to the east-southeast of SCC-105, and approximately 125 meters east of mineralized holes previously drilled by ASARCO of Tucson, Arizona. SCC-109 intersected copper mineralization dominantly as atacamite in fractures beginning at a downhole depth of approximately 657 meters and continuing for over 47 meters. This area is open for expansion to the north, east and south from SCC-109.

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. These leachable minerals are amenable to a solvent extraction/electrowinning ("SX/EW") process allowing for direct copper cathode production.

Typhoon anomaly depths and locations at the Far Southwest Anomaly plot above and adjacent to sulfide bedrock chargeable zones, this is interpreted to be due to cultural interference from a gas pipeline.

High-grade assay results continue from Santa Cruz Deposit infill drill program

Infill drilling continues to return assay results that both confirm the current resource and further refine our geologic understanding of the Santa Cruz Deposit. A recent program highlight included the partial return of assays from drill hole SCC-025 which targeted an area of high-grade mineralization located in the southern area of the deposit.

*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.

Mining, metallurgical, geotechnical and hydrological trade-off studies are nearly complete and will collectively form the overall framework to support the Preliminary Economic Assessment ("PEA") for the Santa Cruz Project. The PEA is scheduled for completion during the second quarter of 2023.

Quality Assurance/Quality Control (QA/QC) Procedure

Ivanhoe Electric employs a comprehensive quality assurance and quality control protocol across all aspects of the Company's data collection, sampling and analytical procedures. Recovered drill core is inspected, logged, and thoroughly marked for sampling at 2-meter intervals. Sampled drill core is sawn into two lengthwise halves of which one-half of each drill core is maintained for future reference and the other half of each drill core is sent to Skyline Assayers and Laboratories of Tucson, Arizona, USA or Société Générale de Surveillance SA ("SGS") of Vancouver, British Columbia, Canada, both of which are ISO 17025 accredited laboratories, to complete all sample preparation and assaying. Samples are analyzed employing total copper, total molybdenum, and sequential copper assaying for acid-soluble and cyanide-soluble copper determinations. Laboratory analysis also employs four-acid ICP-MS analysis for silver and lithogeochemical determinations. For quality assurance and quality control purposes, certified standards, blank samples, and controlled sample duplicates are inserted into the sample stream at prescribed intervals and conditions to monitor laboratory performance.
