Name of the Project
Costa Fuego copper project.

Coastal range of the Atacama region, Chile.

Project Owner/s
Costa Fuego comprises the Productora, Cortadera and San Antonio mineral resources, situated within a 10 km radius.

The Productora deposit is 100%-owned by Chilean incorporated company Sociedad Minera El Aguila SpA (SMEA). SMEA is a joint venture company, 80%-owned by Sociedad Minera El Corazón Limitada (a 100% subsidiary of Hot Chili) and 20% owned by CMP Productora (a 100% subsidiary of Compañía Minera del Pacífico).

The Cortadera deposit is controlled by Chilean incorporated company Sociedad Minera La Frontera SpA (Frontera) – a subsidiary company 100%-owned by Sociedad Minera El Corazón Limitada, which, in turn, is a 100% subsidiary of Hot Chili.

The San Antonio deposit is controlled by Frontera and has an option agreement with a private party to earn a 90% interest.

Project Description
The results of the preliminary economic assessment (PEA) outline a low-risk, long-life copper project benefiting from low startup capital and a high copper-equivalent metal production profile of more than 112 000 t/y over a 16-year mine life, including 95 000 t copper and 49 000 oz gold during primary production (first 14 years).

The PEA proposes a combined openpit truck-and-shovel operation and an underground block cave using centralised processing for a conventional large-scale copper mine producing concentrate and copper cathode.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
In the base case ($3.85/lb), the project has a pretax net present value, at an 8% discount rate, of $1.54-billion and an internal rate of return of 24%, with a payback from first production of 3.5 years.

Capital Expenditure

Planned Start/End Date
Not stated.
