IVANHOE ELECTRIC TO ACQUIRE TUNNEL BORING MACHINE SYSTEM
In Late 2025, Ivanhoe Electric Identified the Opportunity to Acquire a Specialized Robbins Crossover Tunnel Boring Machine and Material Handling System for Project Development
After Initial Review, Ivanhoe Electric Secured the Option to Acquire in March 2026
Since January, Ivanhoe Electric Has Worked with Robbins and Conducted Detailed Due Diligence, Including Two Site Visits to the Grosvenor Site
Upon Completion of Diligence and Extensive Trade-off Studies, Ivanhoe Electric Determined the Robbins Crossover TBM is Ideally Suited for the Variable Ground Conditions at Santa Cruz
Ivanhoe Electric Informed Robbins of Intent to Acquire TBM on May 8th
