Name of the Project
Proyecto Touro copper project.

Location
The project is located in the A Coruña province of the Galicia region, in north-west Spain.

Client
Atalaya Mining.

Project Description
A prefeasibility study (PFS) on Atalaya Mining’s proposed Proyecto Touro copper project has determined that it will be profitable. It comprises several deposits of which four – Arinteiro, Vieiro, Bama and Brandelos – have previously been mined; and two – Monte de las Minas and Arca – have not been mined.

The project has proven and probable reserves of 90.91-million tonnes grading 0.43% copper, for contained copper of 392 000 t.

The PFS envisages the construction of an openpit mine and concentrator, with average yearly production of 30 000 t of copper and 70 000 oz of silver in concentrate.

The proposed flowsheet uses conventional crushing and semiautogenous/ball mill grinding, followed by a flotation recovery circuit and concentrate thickening and filtration.

The concentrator and associated service facilities are designed for an initial Phase 1 plant of six-million tonnes a year and then a Phase 2 upgrade to increase plant throughput to ten-million tonnes a year before Year 8.

The project will use in-pit tailings disposal for a substantial part of the mine life, owing to the multiple pit mine operating plan.

During the initial years of operation, tailings will be stored in a surface tailings management facility (TMF). After Year 8, tailings will be stored in the exhausted Vieiro and Arinteiro openpits. The surface TMF will have an impervious liner and a capacity of 44-million tonnes of tailings, while the in-pit TMF will store 47-million tonnes of tailings. 

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a post-tax net present value, at an 8% discount rate of $180-million using a long-term copper price of $3/lb and an unlevered internal rate of return of 20.5%.

Value
Preproduction capital expenditure is estimated at $165-million, with an additional expansion capital estimate of $30-million in Year 8.

Duration
The project will take two years to develop and will operate for 12 years.
