PHOENIX, AZ / ACCESSWIRE / February 22, 2024 / Ivanhoe Electric Inc. ("Ivanhoe Electric") (NYSE American:IE)(TSX:IE) is pleased to provide a comprehensive update on the ongoing exploration activities at its projects located in Arizona, Utah, and Montana.

Infill and step-out drilling at the Verde Domain within the Santa Cruz deposit confirms continuity of the Verde Domain and provides encouragement for additional similar discoveries

As first reported in our January 8^th, 2024 news release, infill and technical drilling at Santa Cruz has confirmed the presence of high-grade soluble copper within mineralized Oracle Granite. We refer to this area as the Verde Domain.

Drilling within the Verde Domain includes seven drill holes totaling approximately 324 meters. Additional assays have been received from three drill holes, as noted in Table 1 further below.

The Verde Domain boasts higher copper grades, better rock mass conditions and lower water flow rates compared to previous modeling of the surrounding sediments. The improved ground characteristics combined with higher copper grades provide significant upside potential in terms of possible mining method, mining rate, and metallurgical recovery compared to what was modeled for this area in the Santa Cruz Initial Assessment.

New highlighted assay intercepts at the Verde Domain include:

• Drill hole SCC-150 intersected: 6.43 meters @ 5.99% Total Copper (5.90% Total Soluble Copper) composed of intense atacamite mineralization (from 632.89 meters depth)
• Drill hole SCC-183 intersected: 19.81 meters @ 2.64% Total Copper (2.66% Total Soluble Copper) composed of strong to intense atacamite mineralization (from 641 meters depth)
• Drill hole SCC-186 intersected: 59.26 meters @ 2.60% Total Copper (2.67% Total Soluble Copper) composed of strong to intense atacamite mineralization (from 625 meters depth)

Recent Verde Domain drilling has intersected additional visual mineralization including:

• Drill hole SCC-192: 34 meters (645-679 meters) of strong atacamite mineralization
• Drill hole SCC-196: 68 meters (613-681 meters) of strong atacamite mineralization.

Assays for the holes 192 and 196 are pending.

Previously released intercepts at the Verde Domain include:

• Drill hole SCC-005 intersected: 57.00 meters @ 3.52% Total Copper (2.77% Total Soluble Copper) composed of strong to intense chrysocolla, atacamite, and locally chalcocite mineralization (from 636.00 meters depth)
• Drill hole SCC-125 intersected: 56.60 meters @ 3.22% Total Copper (3.16% Total Soluble Copper) composed of strong to intense atacamite and locally intense chalcocite mineralization (from 598.00 meters depth)

A total of seven drill holes have intersected the Verde Domain. New assays from the three recent drill holes combined with previously reported intercepts, continue to support the high-grade continuity and potential for extension to the northwest and southeast as shown in Figure 1 below.

Current exploration drilling at the Tintic Project, in Utah focuses on the source of mineralization of historical mines

Eleven diamond drill holes totaling 11,568 meters have been completed since the commencement of exploration drilling in late 2022. Two rigs were operational throughout the spring and summer of 2023. We reduced to one rig for the winter months.

Drilling at Sunbeam intersects porphyry system, drilling continues at Mammoth

Drilling in the Silver City area has intersected part of a porphyry system associated with the Sunbeam Typhoon^TM chargeability anomaly in drill hole TTD-016 (assays pending). Abundant sulfide-bearing veins are present from 800 meters to the end of the hole at 1435 meters. While visible copper mineralization appears low, the features seen in this hole are common on the margins of many large porphyry systems. This is the first hole to have tested the Sunbeam Typhoon^TM anomaly directly, and there is potential to vector towards more copper-rich portions of this large exploration area with future drilling in 2024.

This Sunbeam porphyry system is thought to be part of the source of mineralization in the Silver City area and separate from the source of mineralization at Mammoth and Grand Central.

Exploration drilling over the winter has moved to test below the Mammoth Mine, where a vertical copper and gold-rich breccia pipe was mined from the 1870s to the 1930s and produced significant high-grade ore. The deposit may extend below the water table, where historical mining stopped, but mineralization is believed to continue, as described in our September 2022 news release. The goal of our drilling efforts, beginning with TTD-017, is to intersect this mineralization at depth, and provide support for a potential porphyry source in the Mammoth area.

Typhoon^TM results and additional assays received from the Hog Heaven Project, Montana

Drilling at Hog Heaven, with one rig, continues to step out in search of the porphyry copper source. The drilling continues to intersect high sulfidation epithermal style mineralization while this search continues, steadily expanding the footprint of this system.

HHD-012 intersected 157 meters of high sulfidation epithermal mineralization approximately 150 meters to the southwest of the nearest hole (HHD-010). This intercept is of a similar grade and quality to that seen in previously reported holes, and demonstrates that the Hog Heaven epithermal system has growth potential to the west of the Flathead Mine.

HHD-012 intersected:

• 156.88 meters @ 0.34 g/t Au, 18.77 g/t Ag, 0.09% Cu, 0.24% Pb, 0.22% Zn (from 282.12 meters)
• Including 49.92 meters @ 0.40 g/t Au, 29.51 g/t Ag, 0.11% Cu, 0.40% Pb, 0.22% Zn (from 282.12 meters)

Drill hole HHD-012 has been successful in opening a large new area prospective for additional shallow high sulfidation epithermal mineralization and the underlying porphyry source. Mineralization intersected by HHD-012 remains open in multiple directions and to depth.

One rig remains in operation through the winter where drilling will focus to the west to determine how far the system extends. Drill hole HHD-014, currently underway, has intersected additional high sulfidation epithermal mineralization and alteration an additional 250 meters to the west.

In November 2023, we conducted a Typhoon^TM geophysical survey covering approximately 10 km² of land, which was designed to cover the core areas of known prospectivity. The Typhoon data, as inverted by CGI, has extended the depth of investigation compared to prior surveys, and given greater confidence in deep targets. A review of these results and target prioritization is underway.
