Alta Copper Provides Update on Preliminary Economic Assessment, Drilling and Community Relations

VANCOUVER, British Columbia, Sept. 08, 2023 (GLOBE NEWSWIRE) -- Alta Copper Corp. (TSX: ATCU; OTCQX: ATCUF; BVL: ATCU) (“Alta Copper” or the “Company”) is very pleased to provide an update on significant developments and progress to date on several fronts which will now set the stage for further development at its 100% owned Cañariaco advanced staged copper project.

Highlights

• Optimized Preliminary Economic Assessment ("PEA") advancing as planned with recent positive developments incorporating 3D Geological Modelling with results targeted to be published in Q4;
  
• Updated 3D Geological Model Identifies Significant Mineralization Potential and High Priority Drill Targets which will provide the foundation for a staged 20,000-meter drilling program in two phases which is targeted to commence in early 2024;
  
  Drilling will focus on the under explored Cañariaco Sur porphyry copper gold deposit, the undrilled Quebrada Verde porphyry target and further enhancement of the Cañariaco Norte deposit;
  

• 40 Platform drill permit application for up to 47,000 meters of drilling is nearing completion; and
  
• Community Relations advancing by way of a Benefits Agreement with the community closest to the Cañariaco Project while also further ratifying future commitments for the development of sustainable projects in the area.
  

Joanne C, Freeze, President & Chief Executive Officer, commented “We are very excited to see the recent results of Whittle Consulting optimization work inclusive of the expected benefits of the 3D Geological Model which will incorporate Cañariaco Sur and higher-grade copper at Cañariaco Norte. We are equally pleased with the recent gains with the Community which we will continue to advance as we further engage by way of our community offices and field activities in preparation of the upcoming 20,000-meter drilling program.”

Preliminary Economic Assessments
Whittle Consulting Pty Ltd (“Whittle”) was engaged for purposes of advancing project optimization which involves a rigorous analytical and computational process using Whittle's Strategic Mine Planning software and Integrated Strategic Planning concepts (Refer to Alta Copper News Release dated April 27, 2023 for more details). To date, Whittle has completed 63 iterations on the mine plan pit shells and will be conducting additional iterations as soon as the new 3D Geological Modelling is incorporated. The new 3D Geological Model has identified some very compelling alteration effects on the deposit, which are linked to higher copper grades.
