The Toqui mine is located in Chile 's Region XI, approximately 1,350 kilometres south of Santiago and 120 kilometres northeast of Coyhaique
(view map).

The Toqui deposit was discovered in the early 1970's. Metallgesellschaft AG owned the property for a number of years and then sold it to a Chilean entrepreneur.

The property was subsequently purchased by Lac Minerals. In 1994, Barrick Gold Corporation acquired Lac Minerals which included El Toqui. Breakwater purchased Toqui in August 1997.

The Toqui property includes the Doña Rosa zinc/gold mine and the San Antonio and Mallin-Monica zinc/lead mines, the Estatuas mine and the Concordia deposit. Processing is carried out through a 1,500 tonne per day concentrating plant.

Zinc/gold mineralization at Toqui occurs as manto deposits hosted by an 8 metre to 12 metre thick bed of fossiliferous limestone, known as the Main Manto unit. The Toqui deposits all dip gently to the south, and are amenable to room and pillar mining, with 11 metre rooms around 8 metre pillars. The Doña Rosa Mine is accessed via an adit.
