Ivanhoe Electric to Host Investor Conference Call Today at 12pm ET

PHOENIX, AZ / ACCESSWIRE / February 14, 2023 / Ivanhoe Electric (NYSE:IE)(TSX:IE) Executive Chairman, Robert Friedland and President and Chief Executive Officer, Taylor Melvin are pleased to provide an updated Mineral Resource Estimate for the Santa Cruz Copper Project ("Project") located west of Casa Grande, Arizona.

The updated Mineral Resource Estimate now includes the first Mineral Resources declared at the East Ridge Deposit directly adjacent to the Santa Cruz Deposit and at the Texaco Deposit approximately one mile to the northeast.

The updated Mineral Resource Estimate utilizes higher cut-off grades than the 0.39% cut-off used in the December 8, 2021 Santa Cruz Project Mineral Resource statement. The higher cut-off grades were used to account for the consistency and thickness of the higher-grade exotic, oxide and enriched copper domains, which support a more selective, lower-impact bulk mining method.

The resource at the Santa Cruz Deposit reflects a 0.70% total copper cut-off, while the resources at East Ridge and Texaco reflect a 0.90% and 0.80% total copper cut-off, respectively. Even at these higher cut-off grades, the overall project-wide contained copper in Indicated Mineral Resources increased by 11%. Importantly, project-wide contained copper in Indicated Mineral Resources, excluding primary sulfide mineralization, increased by 86%.

Mr. Friedland commented: "We are making great strides towards our ambitious goal of constructing a low-carbon footprint, underground copper mine with minimal surface disturbance in Arizona. The maiden resource estimates for the East Ridge and Texaco Deposits were founded on the knowledge gained from our 26.5 km2 (6,500-acre) proprietary Typhoon™ 3D induced polarization and resistivity geophysical survey conducted in 2022 and build on the success we have achieved at the Santa Cruz Deposit. Today's announcement is an important milestone that underpins the future development potential of the Santa Cruz Copper Project."

Mr. Melvin commented: "This resource update is the culmination of a tremendous effort by our team at Santa Cruz. The drilling to date increases our confidence in the high copper grades at the Santa Cruz Deposit and confirms the growth potential at the nearby East Ridge and Texaco Deposits. The updated resource provides an excellent foundation for our initial economic assessment, which we expect before the end of Q3 2023."

Highlights of the Updated Santa Cruz Project Mineral Resource Estimate

Using a 0.70% copper cut-off grade, Indicated Mineral Resources at the Santa Cruz Project total 226.7 million tonnes grading 1.24% total copper (2.8 million tonnes of contained copper), and Inferred Resources total 149.0 million tonnes grading 1.24% total copper (1.8 million tonnes of contained copper).

The Santa Cruz Deposit remains the largest deposit at the Santa Cruz Project with Indicated Mineral Resources totaling 223.2 million tonnes grading 1.24% total copper and Inferred Mineral Resources totaling 62.7 million tonnes grading 1.23% total copper.

Importantly, the Santa Cruz Deposit now includes 78% Indicated Resources at higher average grades than the previous estimate, which will form the base for the upcoming Initial Assessment/ Preliminary Economic Assessment ("Santa Cruz IA/PEA"). For comparison, the December 8, 2021 Santa Cruz Mineral Resource Estimate had only 52% classified as Indicated Mineral Resources at an average grade of 0.93% copper.

Figure 1: Santa Cruz Project Updated Mineral Resource Estimate (December 31, 2022 Mineral Resource Estimate)

The initial East Ridge and Texaco Mineral Resource Estimates reflect limited portions of the historically defined areas of mineralization and represent what Ivanhoe Electric has delineated within the past six months. Both East Ridge and Texaco Deposits exhibit significant potential for high-grade copper additions within the structural corridors that control the mineralization. Project-wide, Ivanhoe Electric currently has six diamond drill rigs active on site.

Table 2: Initial Mineral Resource Estimates for the East Ridge and Texaco Deposits (December 31, 2022 Mineral Resource Estimate).

Category	Deposit	Tonnage (millions of tonnes)	Total Copper Grade (%)	Total Soluble Copper Grade (%)	Total Contained Copper (millions of tonnes)	Total Contained Soluble Copper (millions of tonnes)
Indicated	Texaco¹	3.6	1.33	0.97	0.05	0.03
Inferred	Texaco¹	62.3	1.21	0.56	0.8	0.3
Inferred	East Ridge²	24.0	1.36	1.26	0.3	0.3

Texaco Deposit cut-off grade is 0.80% total copper.
East Ridge Deposit cut-off grade is 0.90% total copper.

Refer to Notes on Mineral Resources following Table 5.

The Updated Santa Cruz Project Mineral Resource Estimate is the Result of a Highly Successful Drill Program

The primary focus of the ongoing drilling program at each of the Santa Cruz, East Ridge and Texaco Deposits was to:

Target the higher-grade areas (greater than 1.2% copper) to confirm if the December 8, 2021 Mineral Resource Estimate grade was as outlined in the estimate.
Expand the higher-grade copper areas with a strong focus on the Exotic, Oxide and Chalcocite domains.
Target the structural controls that influence the higher-grade copper domains.
Complete various "twin holes" in proximity to historical drilling which can be compared (geologically, structurally, geochemically, etc.) to each other to determine if significant geological and sampling bias exists.
Upgrade high-grade Inferred Mineral Resources into the Indicated category.
At East Ridge and Texaco, confirm the higher-grade historical intercepts and determine if the higher-grade areas could be expanded.

Collectively, the Santa Cruz drill program delivered on all six of these points.

Ivanhoe Electric's Infill Drill Program at the Santa Cruz Deposit Successfully Expands the Higher-Grade and Leachable Exotic, Oxide and Enriched Domains

With a specific focus on expanding the higher-grade areas of the Santa Cruz Deposit (greater than 1.2% total copper within the Exotic, Oxide, and Chalcocite Enriched domains), Ivanhoe Electric successfully improved the Indicated Resources tonnage in these domains within the Santa Cruz Deposit by 65%. The average copper grade of Indicated Resources in these domains at the Santa Cruz Deposit increased by 10%, contributing to an 82% increase in contained copper metal. These important domains host the high-grade soluble copper minerals that will be the central focus of the Santa Cruz IA/PEA expected in Q3 2023.

Figure 2: Santa Cruz Deposit Indicated Mineral Resource Estimate Comparison between December 8, 2021 and December 31, 2022 within the Exotic, Oxide, and Chalcocite Enriched Domains.

Comparison to the December 8, 2021 Santa Cruz Deposit Mineral Resource Estimate

The updated Mineral Resource Estimate includes a higher copper cut-off grade of 0.70% as the base case, reflective of a higher-grade, more-selective and lower-impact mining method. This compares to the December 8, 2021 Mineral Resource Estimate which applied a "bulk tonnage mining method" 0.39% copper cut-off grade as the base case.

When the updated Mineral Resource sensitivity is compared to the December 8, 2021 Mineral Resource Estimate using the same 0.39% copper cut-off grade, infill drilling at the Santa Cruz Deposit has successfully added 46% more contained copper in the Indicated category.

Santa Cruz Deposit: Inferred	248.8	0.91%	2.3	179.6	0.74%	1.3

Refer to Notes on Mineral Resources following Table 5.

Increased Understanding of Distinct Mineralized Domains at Santa Cruz is Critical to Unlocking the Deposit

Exotic oxide mineralization (Exotic) is of more limited known occurrence and tends to form very high-grade mineralization in paleo-valleys at the contact of the mineralized bedrock and the overlying gravel cover. This mineralization formed in basal gravels through the precipitation of copper that was transported in solution by migrating groundwater. These zones have shown to contain spectacularly high-grade copper.
Supergene oxide mineralization (Oxide) forms the uppermost zone of mineralization and is dominated by chrysocolla (a copper oxide that is 34% copper by weight) and atacamite (a copper chloride that is 60% copper by weight).
Supergene sulfide mineralization (Chalcocite Enriched) underlies the supergene oxide zone and is comprised primarily of enriched chalcocite (a copper sulfide that is 80% copper by weight), with accessory chalcopyrite and pyrite that is partially or completely replaced by chalcocite.
Hypogene sulfide mineralization (Primary) underlies the supergene sulfide zone and consists of chalcopyrite (a copper sulfide that is 35% copper by weight), pyrite, molybdenite, and minor bornite and covellite, hosted within porphyry-style phyllic alteration. Intensity of mineralization is highest around Laramide-age dyke intrusions that cut the mineralized Proterozoic-age Oracle Granite country rock.

Recent Metallurgical Test Results Indicate Potential for High Copper Recovery Rates of up to 94%

The Santa Cruz Deposit has a high copper grade averaging 1.42% copper in the combined Indicated Resource Exotic, Oxide and Chalcocite Enriched Domains.

Ivanhoe Electric believes that the preferred mineral processing method for the higher-grade mineralization will be a combination of agitation leaching and copper sulfide flotation that will recover most of the soluble copper in the Exotic, Oxide and Chalcocite Enriched Domains.

Agitation leach tests undertaken in mid-2022 verified historical test results and after adjusting the particle size distribution, acid-soluble copper recovery of 92% was achieved.

Ivanhoe Electric subsequently conducted a leach-float test program in which the same mill composite sample used in prior testing was subjected to the standard leach procedure developed earlier in the year. Three standard leach tests were conducted, followed by flotation of the leach residue at different grind sizes. Ivanhoe Electric successfully confirmed that up to 94% total copper recovery with the leach-float circuit was achievable at the Santa Cruz Deposit.
