The width of the veins and veinlets that make up this stockwork varies from a few centimeters to 1.20 meters, and have typical textures of shallow epithermal environments (crustiform-coloform, pseudomorphs according to calcite, massive chalcedony, etc.). In addition, several episodes of hydrothermal brecciation have been identified, notably a hydrothermal explosion chimney, whose outcrop covers an area of ​​4 hectares. The mineralization does not only occur in the veins and veinlets, but it is also found in the box rock (in the sedimentary and tuff levels).
In this block three mineralizing episodes have been identified, of which the second and the third present a great areal development and contribute gold to the system. The last two mineralizing episodes are temporarily separated by a phreatomagmatic breccia event, associated with the possible intrusion of a rhyolitic dome.

Episode I is formed by a system of massive quartz veins with replacement textures according to calcite (lattice bladed and parallel bladed), which do not present anomalous values ​​in preciuos metals. It is crossed by a system of quartz veins banded in the form of stockwork, with anomalous gold contents of a maximum of 0.7 ppm. This vein system has limited areal development.

Episode II is characterized by a stockwork of quartz-chalcedony (chalcedony predominates), with coloform-crustiform textures, and abundance of hematite silica bands which gives a characteristic reddish color to these veins. It is also associated with several events of hydrothermal brecciation. Presents gold grades ranging from 0.1 ppm to 1.9 ppm. From the surface sampling, six samples with gold content between 1 ppm and 1.9 ppm corresponding to this episode were detected, while in one of the drilling a value of 4 ppm was obtained in a sample of one meter. The veins and veins of this episode predominate in the central sector and SE of Cerro Choique, and cover an approximate area of ​​80 hectares.

Episode III, temporarily younger, is of a higher temperature and has higher gold content than the previous one. It is characterized by a stockwork of veins and veinlets of banded quartz, with a crustiform texture, with white and pink bands. They are concentrated mainly in the NW sector of Cerro Choique, covering an area of ​​approximately 20 hectares, although the system is open to the NW. In the entire Cerro Choique area, 23 geochemical rock samples have been obtained that exceeded 1 ppm Au, of which 15 samples correspond to this episode. These samples vary between 1 to 4 ppm of gold. This mineralizing episode represents a reactivation of the epithermal system as a result of the intrusion of a rhyolitic dome, evidenced on the surface by the presence of a phreatomagmatic brecciation event. This reactivation brought precious metals into the system. Approximately 900 surface geochemical samples were taken (rock and soil samples), 1,010 samples from drilling, 4,650 meters of exploratory trenches and 1,076 meters of reverse AR drilling. Both the trenches and the holes were carried out in the first season of 1996. In the years following the survey campaign, geological mapping studies and intense geochemical sampling were carried out, concluding that the main identified exploratory targets were not drilled during the campaign 1996. Soil sampling carried out in 2012 showed as a main conclusion that the mineralized system is open at the NW end.

In summary form, the rock sampling presented the following gold results:
23 samples: 1.00 to 4.00 ppm Au
32 samples: 0.50 to 1.00 ppm Au
85 samples: 0.25 to 0.50 ppm Au
310 samples: 0.10 to 0.25 ppm Au

In Choique SE Block, a system of veins of white quartz alternating in bands with granular gray crystalline quartz of greater temperature, associated with levels of gaps (veins of gaps) has been detected and is also interpreted as an epithermal system exposed in the levels intermediate Two branches of veins have been identified in an approximate area of ​​1,500 m x 300 m in width NW-SE. These veins are open towards both ends. In this block there is also a quartz-fluorite vein system where the old works of NE-SW fluorite and an intensively silicified and breached tuff level are interpreted as a Cap Silica. The geochemical sampling performed detected interesting anomalies of gold and trace elements such as mercury, arsenic and molybdenum, in rock samples taken from the epithermal quartz veins. According to the geological model proposed for this deposit, several exploratory targets can be defined. The main ones are:

1. In the superficial sectors, mineralization of the disseminated type associated with the levels of permeable rocks (sedimentary and tuff), and systems of veins and veins in stockwork. The latter mainly in the sectors associated with the third mineralizing episode, where siliceous pulses with higher gold content have been detected.

2. Field evidence suggests the presence of a shallow intrusive body (rhyolitic dome) that generated a phreatomagmatic breccia, prior to the third mineralizing event. This opens the possibility of exploring new targets following the model of epithermal deposits associated with rhyolitic domes. In the Macizo del Deseado (Province of Santa Cruz), interesting mineral deposits have been discovered associated with rhyolitic domes complexes (such as the Las Calandrias Project -Mariana Resources- and Falcon -Yamana-), where the mineralization is disseminated inside and edge of the domes (gaps, stockwork and veins).

3. In the medium and deep levels of the system, the feeders of the system are interesting exploratory targets in search of vein systems with high grades in noble metals and possibly also base metals. The mineralized zone of the SE Block has the potential to find vetiform systems rich in gold.
