The vein systems display typical epithermal quartz vein textures, including colloform banding, vugs and brecciation with chalcedonic breccia matrix and silicification of wall rocks. The epithermal quartz vein contained about 2% disseminated pyrite. Gold typically occurs along the central core portion of the veins. Silver values greater than 100 g/t Ag are common in veins and elevated copper values were obtained. The epithermal quartz veins and adjacent silicified zones range in width from approximately 1 m to 6 m.

The Encrucijada property is underlain by Paleocene to Eocene andesitic lapilli tuff and later andesitic porphyry or crystal tuff. These units are well exposed over then eastern two thirds of the property. Over most of the western portion of the property and a few large patches of the eastern area bedrock is covered by up to 5 m of dacitic ash tuff and gravel.

Veins B and C occur on the south side of Quebrada Corcovado and extend for 500 m and 400 m along a west-southwest trend respectively. The veins are separated by 75 m to 100 m. Both veins have yielded a number of chip samples containing in excess of 1 g/t Au along the more continuous central portion of the vein. Vein C produced the best intercept of the drilling campaign of 1.8 g/t Au over a 4 m drill interval. Including the altered and silicified wall rocks the structure ranges to 6 m wide in the vicinity of this intercept.

Veins D and E are located on either side of a shallow quebrada 1.5 km due south of Quebrada Corcovado. Both veins trend west-southwest and are separated by 75 m to 150 m. Vein D can be traced for 400 m and Vein E for 500 m. Vein E is the more interesting of the two as it displays multiple en echelon splays in the hanging wall of the main structure. Rock chip samples collected from these veins have all been less than 1 g/t Au.
