IVANHOE ELECTRIC ON-TRACK TO DELIVER SANTA CRUZ COPPER PROJECT PRELIMINARY FEASIBILITY STUDY IN Q2 2025
Ivanhoe Electric Inc. has provided an update on the continuing progress at the company's Santa Cruz copper project in Arizona.
President and chief executive officer Taylor Melvin commented: "We are encouraged by the ongoing progress at our Santa Cruz copper project. Our preliminary feasibility study remains on track and on budget for completion in the second quarter of 2025. We are pleased to have received approval by the City of Casa Grande for our general plan amendment, and we look forward to submitting key permit applications in early 2025."
The Santa Cruz copper project preliminary feasibility study will define an underground mining operation supported by a mine plan and an updated mineral resource and reserve estimate
Ivanhoe's preliminary feasibility study (PFS) is being conducted under the standards of U.S. Regulation S-K 1300. The study will include a detailed mine plan that will be supported by an updated mineral resource and reserve estimate resulting from the company's infill drilling and test work activities. The study will be used by Ivanhoe Electric to make an investment decision and pursue long-term project financing.
The Santa Cruz copper project preliminary feasibility study is now 50 per cent complete, with several significant milestones achieved, and on track for completion in Q2 2025:
- 120,000 metres of new drilling completed since December, 2022, mineral resource estimate (MRE) to support preliminary feasibility study;
- Significant advancements in metallurgy, mine engineering, processing, tailings trade-off studies and mine access planning;
- Studies focused on process design and optimization, power, water management, and environmental/permitting are continuing.
Metallurgical studies, conducted by Blue Coast Research Ltd. of British Columbia, Canada, showing high copper recoveries and presence of recoverable precious metal byproducts:
- Up to 98-per-cent recoveries of acid-soluble copper for production of copper cathode;
- Up to 92-per-cent recoveries of flotable copper to produce high-grade copper concentrate;
- Expected to produce a high-grade copper concentrate grading up to 51 per cent copper by weight and high-purity copper cathode meeting London Metal Exchange Grade A standards;
- Identified recoverable precious metal byproducts expected to average two grams per tonne gold and 145.9 g/t silver in the high-grade copper concentrate.
Permitting milestone achieved and major permits in preparation for submittal
In June, 2024, Ivanhoe Electric received approval from the City of Casa Grande for the major general plan amendment for the Santa Cruz copper project, a major milestone for the project. The City of Casa Grande Council unanimously approved amending nearly 3,000 acres of land use designation from neighbourhoods to manufacturing/industry. Key permitting applications are being prepared for submittal in the first half of 2025 in connection with the PFS.
Infill drilling at Santa Cruz deposit demonstrates presence of high-grade domains within the mineral resource estimate
The development drill program at the Santa Cruz copper project included drill holes completed to support metallurgical studies, resource definition and infill, hydrogeology, and geotechnical studies, all of which support the PFS. Infill drill holes were completed to support the conversion of resources from the inferred category to the higher-confidence indicated category.
Infill drill hole SCC-234, completed in the Santa Cruz deposit, intersected higher-than-expected copper grades, with mineralization present as strong chalcocite, atacamite and chrysocolla in bedrock Oracle granite; and porphyry as disseminations, veins and fracture fillings.
Assays from the recently completed development drill program continue to be received and will be added to an updated MRE to support the PFS delivery in Q2 2025. Recent intercepts include:
- 99.4 metres of 2.39 per cent total copper from 738.0 metres, including 46.1 metres of 3.99 per cent total copper from 755.9 metres (hole SCC-234);
- 140.1 metres of 1.56 per cent total copper from 753.4 metres, including 29.0 metres of 2.92 per cent total copper from 799.0 metres (hole SCC-228);
- 101.9 metres of 1.65 per cent total copper from 678.1 metres, including 17.6 metres of 2.37 per cent total copper from 702.7 metres (hole SCC-232);
- 70.2 metres of 1.44 per cent total copper from 551.0 metres and 115.8 metres of 1.12 per cent total copper from 630.2 metres (hole SCC-219A).
