Project Overview
Capstone Copper’s fully-permitted Santo Domingo copper-iron project is located 130 kilometers north-northeast of the city of Copiapó, Chile. Elevation at the site ranges from 1,000 to 1,280 masl, with relatively gentle topographic relief.
The Santo Domingo deposits are located within the Cretaceous Iron Belt (“CIB”) of the Atacama fault zone. The CIB is a segment of the Atacama fault zone approximately 630 km by 40 km in dimension that hosts numerous iron oxide-copper-gold (IOCG) type deposits. Mineralization within the deposit area consists of Stratiform replacement mantos and breccias within tuffaceous sedimentary rocks (e.g. Santo Domingo Sur deposit) and structurally-controlled mineralization along the east–west Santo Domingo fault zone (e.g. Estrellita deposit).
Production will come from two open pit mines, Santo Domingo and Iris Norte. Mine production is based on process plant throughput of 65,000 t/d for the first 5 years and 60,000 t/d from Year 6, producing copper and magnetite concentrates. Capstone are also looking at options to recover cobalt.
An updated feasibility study is in process and expected to be completed in the first half of 2024. The study will optimize the process flowsheet and incorporate recently produced metallurgical testwork and an updated mine plan.
