Projects

We have reviewed hundreds of gold and copper projects in South America but have selected only two that meet our demanding criteria with open high-grade mineralisation, clear upside and compelling drill targets. Both projects are located at moderate altitudes in areas of good infrastructure among supportive communities. With such exceptional projects Turmalina Metals is well poised for rapid discovery and growth.

Our focus is on tourmaline breccias, a deposit style characterized by high gold, silver, copper and molybdenum grades focused within breccia pipes that can exceed 1 km in vertical extent. These breccia pipes form in clusters providing considerable potential for resource growth, and we have consolidated our holdings over the large breccias clusters at both our projects.

Tourmaline breccias have been overlooked as primary targets by many explorers, largely due to the assumption that these breccias are markers for deeper porphyry mineralisation. Prior to acquisition our projects were held and developed by private companies, and as such our portfolio represents the introduction of new projects, new exploration paradigms and new regions into the public space.

The project is located in an arid, sparsely populated area at an elevation of ~2600m. The camp is located 20km by unsealed road to the nearest public road and the state power grid.

San Francisco De Los Andes

One of the highest-grade gold-copper tourmaline breccias ever discovered

The San Francisco de Los Andes breccia is one of the highest-grade tourmaline breccias ever discovered. Limited shallow drilling and channel sampling returned spectacular grades of 2-12 g/t gold and 0.3 to 3% copper over 20-40 m intervals. The mineralogy and geological setting indicates that only the top of the breccia pipe has been exposed, with excellent potential for growth at depth and laterally. Furthermore, San Francisco de Los Andes is only one of over 60 breccia bodies mapped to date on the property.

Turmalina

A high-grade and undrilled copper-molybdenum-gold mine with open mineralisation.

Our Turmalina project hosts the high-grade Turmalina copper-molybdenum mine and the surrounding breccia cluster. The breccia at Turmalina has been defined through mining, rather than through drilling:  A number of private consortiums have mined the top of this large tourmaline copper-molybdenum pipe with no drilling at the deposit or exploration of the surrounding region.

Not only does the extension at depth of this undrilled deposit present a compelling drill target, but Turmalina is only one breccia in a cluster of copper-molybdenum-gold mineralised breccias that have supported small scale workings but have not been sampled or drilled.
