Ivanhoe Electric Subsidiary Cordoba Minerals Reports Intersecting Multiple High-Grade Gold-Copper Veins within the Alacran Deposit at Its San Matias Copper-Gold-Silver Project in Colombia

NEW YORK, NY / ACCESSWIRE / August 8, 2022 / Ivanhoe Electric (NYSE American:IE)(TSX:IE) Chairman and Chief Executive Officer Robert Friedland and President Eric Finlayson are pleased to announce that Ivanhoe Electric's subsidiary, Cordoba Minerals Corp. (TSXV:CDB)(OTCQB:CDBMF), has reported initial diamond drilling results from its ongoing drilling program at the San Matias Copper-Gold-Silver Project in Colombia. Ivanhoe Electric owns a 63.27% interest in Cordoba Minerals with the San Matias Copper-Gold-Silver Project itself being owned 100% by Cordoba Minerals.

Highlights:

• 6,385 meters (24 diamond drill holes) of the initial 25,000-meter in-fill drilling program have been completed within the Alacran Deposit.
• Significant assays returned to date include (see Table 1 for full drill results):
  • ACD087 - 61 meters with 0.99% copper, 0.35 g/t gold and 5.17 g/t silver or 1.17% copper equivalent (CuEq ¹ ).
  • ACD097 - 53 meters with 0.70% copper, 0.70 g/t gold and 6.18 g/t silver or 1.11% CuEq ¹ .
• Mineralized intersections correlate closely with Cordoba Minerals' previously disclosed Pre-Feasibility Study (PFS) Mineral Resource block model.
• Multiple late-mineral gold-copper veins, known as Carbonate Base Metal (CBM) veins, have been intersected within drill holes and are superimposed upon high-grade zones of earlier carbonate replacement copper-gold mineralization.

"We are excited to see the initial in-fill drill holes supporting the higher grade domains in the resource model for the Alacran Deposit. The fact that these domains also host multiple CBM veins brings Cordoba one step closer to understanding the relationship between the CBM and carbonate replacement events," commented Sarah Armstrong-Montoya, President and CEO of Cordoba.

"Results indicate a shared feeder system for the mineralizing fluids and point towards excellent exploration potential to depth, including for a porphyry copper-gold source."

Initial drill results show strong correlation with Cordoba's previously announced PFS resource block model

Cordoba commenced an initial 25,000-meter in-fill drill program in May 2022, which is part of the 40,000-meter in-fill drilling campaign planned by it to update its previously disclosed mineral resource and mine plan at Alacran. This initial drill program focuses on the northern and central areas within the Alacran Deposit which hosts high-grade mineralized zones with considerable widths (Figure 1).

Cordoba reports that a total of 6,385 meters in 24 diamond drill holes of the initial drill program have been completed to date. The initial drill assays confirm not only the wide higher grade domains of chalcopyrite-pyrrhotite copper-gold carbonate replacement mineralization within the mineral resource block model but also the presence of multiple late-mineral CBM veins (Figures 2 to 5).

CBM veins offer significant upside potential for contained gold in the Alacran Deposit

CBM veins are a style of structurally-controlled gold, silver and base metal mineralization found in association with porphyry intrusions. Spectacularly large and high-grade examples include the Porgera gold deposit in Papua New Guinea and the Buritica deposit in Colombia.

The average grade of the CBM veins identified within Alacran Deposit is unknown. Bonanza grade gold was previously reported by Cordoba in January 2017 in drill hole ACD036 (see Table 2), which returned 0.90 meters of 4,440 g/t gold, 10.25% copper, 24.70% zinc and 347 g/t silver (Figure 6).

In-fill drill holes ACD087, ACD097, ACD114 and ACD115 during the current campaign have intersected en-echelon CBM veins overprinting earlier chalcopyrite-pyrrhotite copper-gold carbonate replacement mineralization. The predominance of arsenopyrite with minor pyrite and sphalerite in the CBM veins, coupled with the pervasive chlorite-white mica alteration and carbonate gangue, is diagnostic of an intermediate sulfidation epithermal event. There is significant potential for these veins to extend to depth, potentially towards a causative porphyry intrusion.

It is difficult to currently assess how much gold these CBM veins may contain within the Alacran Deposit. However, given the clear presence of coarse-grained gold, as demonstrated in drill hole ACD036, it is likely that there is a significant nugget-effect at play. Should that be substantiated it provides the potential for an increase in contained gold that is not reflected in the current mineral resource statement of Cordoba.

*Intercepts calculated using a:

• 0.3% CuEq cut-off with 6m maximum internal dilution and a 6m minimum width.
• 1.0% CuEq cut-off uses 4m maximum internal dilution and 4m minimum width.
• 2.0% CuEq cut-off uses 2m maximum internal dilution and 2m minimum width.
• The "includes" & "and" intercepts are found within the preceding intercept, and represent higher grade portions therein.
• True width intervals of the mineralization are interpreted as being between 90-100% true widths from oriented diamond drill core and sectional interpretation.
• Copper equivalent calculations assume a US$2.50/lb copper price and a US$1300/Oz gold price.
• For intercept calculations: sample assays of copper, gold and copper equivalent are all capped to 10% Cu, 10 g/t Au, and 10% CuEq.
