Santo Domingo

Santo Domingo is a fully-permitted copper-iron-gold project, owned 70% by Capstone and 30% by Korea Resources Corporation (KORES), the Korean state-owned resource acquisition enterprise. Santo Domingo has all construction permits in hand, including approval of a Closure Plan. Located in a mining-friendly region, 50 kilometres southwest of Codelco's El Salvador copper mine and 130 kilometres north-northeast of Copiapó, near the town of Diego de Almagro in Region III, Chile, with support from the local community and government. Elevation at the site ranges from 1,000 to 1,280 metres above sea level, with relatively gentle topographic relief.

Capstone released results of an updated technical report in February 2020 that includes a higher level of CAPEX/OPEX certainty, additional key permits and the development in Section 24 of a Preliminary Economic Assessment with respect to cobalt production. See the February 19, 2020 news release for full details.

A strategic process is in place to right-size or monetize Capstone’s ownership.
