Name of the Project
Santo Domingo copper/iron/gold project.

Location
Region III, Chile.

Project Owner/s
Capstone Copper.

Project Description
The 2024 feasibility study has outlined a robust project that is expected to average 106 000 t of copper, 3.7-million tonnes of iron concentrate and 35 000 oz of gold over the first seven years of the mine plan. Over the project’s 19-year life-of-mine (LoM), production is expected to average 68 000 t of copper, 3.6-million tonnes of iron concentrate and 22 000 oz of gold.

The LoM is supported by a 436-million-tonne mineral reserve estimate at a copper grade of 0.33%, iron-ore grade of 26.5% and gold grade of 0.05 g/t. Total measured and indicated resources are estimated at 547-million tonnes at a copper grade of 0.31% and a gold grade of 0.04 g/t, including 506-million tonnes with an iron grade of 25.8%.

Santo Domingo includes the development of two openpit mines using conventional drilling, blasting and loading with electric and hydraulic shovels. The project includes a copper/iron concentrator designed to process a maximum of 72 000 t/d using autogenous grinding milling, with conventional rougher cell flotation, regrinding and classification, with Jameson Cells used in the cleaner, cleaner scalper, cleaner scavenger and recleaner stages. Magnetite iron will be recovered from the copper rougher tailings using low-intensity magnetic separation.

The planned infrastructure includes a tailings storage facility, an iron magnetite concentrate pipeline and a third-party-operated desalination plant and desalinated water supply pipeline, a port-located magnetite iron concentrate filter plant and stockpile, a port-located copper concentrate storage building, shiploading facilities and a high-voltage transmission line, as well as on- and off-site infrastructure and support facilities.

Potential Job Creation
