LA BRECHA PROJECT
La Brecha Project is located 7 km to the South from Los Menucos town, on Río Negro province. The mine property covers a surface of 2,700 hectares.

The regional setting belongs to the geological province of the Nordpatagonic Massif. The most important unit, by its metallogenic implications, is given by a volcanic event characterized by flows and intrutions called Los Menucos Complex and it is constituted by rhyolites, dacites, andesites and their associated pyroclastic rocks.
A hydrothermal breccia dike of E-W strike was detected in the explored sector. This structure form part of a major regional structure very evident in the satellite images.
Vein structure has a continuous extent over 3,000 meters with an average width over 40 meters while in some areas it reaches more than 100 meters. Cº El Guacho is located at 3,000 meters on the North of La Brecha structure. On Cº El Guacho there is an inclined layer with 35 meters width and it is composed by light-blue massive silica. This bed is pierced by a stockwork system of veins and veinlets of quartz chalcocedony and filled with red microcrystalline silica.
On the explored area an expeditious sampling was done, from it 13 samples were taken but they did not reveal any anomalous values in precious metals. Only one sample from Cº Guacho stockwork showed gold anomalies (196 ppb). However, the textures evidences (colloform - crustiform, bladed, etc.) recognized on the main structure of La Brecha and on the stockwork zone of Cerro Guacho, indicate us that we are on the upper zone of a low sulfidation epithermal system.
