Property Geology

The geology of the Bramaderos property comprises Cretaceous volcanics of the Celica Formation which have been intruded by quartz diorite and hornblende diorite porphyritic intrusions along NNE- to NE-trending structures, and potentially localized by WNW-trending cross-structures.

Mapping by Ecuador Gold defined a minimum 3km by 1km size intrusion of hornblende diorite which is elongate WNW, hosts the main mineralization at the Brama porphyry prospect, and defines a WNW-tending ridge. Further north lies a mapped quartz diorite intrusive of similar dimension intruding the Celica Formation. Smaller bodies of younger rhyodacite tuff overlie these intrusions.

Extensive zones of argillic alteration affect the Celica Formation over an area exceeding 4 x 1 km and were mapped by EcuaGold as phyllic alteration forming a NNE-trending belt that encompasses the Brama and Porotillo prospects as well as other centres of porphyry stockwork mineralization further to the SSW. In addition, a >2km by 1km NNW-trending belt of argillic alteration at the Limon porphyry prospect is associated with a strongly leached cap above locally exposed porphyry quartz vein stockworks. Further afield the extensive areas of argillic alteration are transitional through intermediate argillic alteration to peripheral propylitic alteration.

Several centres of potassic alteration are associated with the main areas of outcropping quartz stockwork mineralization at the porphyry prospects.
