Mineralization occurs as a series of quartz veins that outcrop along a strike length of 1,150m cutting rhyolite tuffs and a volcanic dome. The system strikes North-South for 450m then changes strike to NNE for about 700m. Quartz vein float extends additional 450 m to the southeast. The system consists of multiple sub-parallel veins and stockwork zones over a width of between 15m and 170m. Individual veins vary in width from <1m up to about 12 m. The veins dip at 55° to sub-vertical to the east, with some conjugate veins dipping to the west.
Quartz and silica occur in a variety of forms, including multiple generations of opal to banded chalcedony, colloform banding, late stage coarse-grained
The quartz and silica textures are interpreted to indicate the upper part of the system, and in particular the bladed quartz after carbonate is generally interpreted to indicate boiling of the hydrothermal fluid. The level of exposure is interpreted to be above the main boiling zone of precious metals deposition, which is the target.

Exploration to Date
A program of detailed geological mapping and rock sampling was carried out in order to define zones of anomalous gold and trace element geochemistry, as well as areas showing textural and vein characteristics of epithermal systems. A total of 167 rock-chip samples were collected. The analyses returned values up to 184 ppb Au un to 1,490 ppm As, up to3,040 ppm Sb, up to 14.5 ppm Hg, and over 10,000 ppm Ba, and some anomalies in Mo with a range un to 176 ppm Mo. Base metals returned low values consistent with the upper level location of the project.
The geochemical signature of low anomalies of Au, strongly anomalous As, Sb, Hg and Ba, and low Ag, Cu, Pb and Zn are characteristic of the upper levels of an epithermal system.
A two-stage exploration program is recommended for Vinata. The first stage is detailed geological mapping, geochemical rock and soil sampling along the extensions of the vein trend to the northeast and southeast. The second stage is a preliminary program of reverse circulation (RC) drilling on the outcropping vein zone, consisting of 9 holes totaling 2,580 m.
