Geological Considerations

The auriferous rivers in this area are accumulated forming alluvial terraces in their riverbanks. The distribution of gold is erratic, both in its horizontal projection as well as in its vertical projection. The conglomerate material is made up of blocks, clasts, gravel, fine gravel, and sand that has a predominantly igneous origin. The black sands, which are the result of pre concentrations during the recovery of gold, have magnetite and ilmenite for the most part. The gold is found in a free state inside the sands, and its distribution is erratic, around a 70 percent is situated in the mesh 60 and 100. the bigger auriferous particles correspond to the first layer.

Hypothetical area 2
This deposit is a conglomerate layer with a dip between 55 degrees to 70 degrees SW; the thickness varies from 0.7 to 1.5 meters and the course of N 40 degrees W to S 40 degrees E. The layer of earth is made up of pebbles that have a predominance of quartz, quartzite, and in smaller amount, intrusive rocks and effusive, whose sizes are under that of 0.08 meters of mayor axis. These pebbles have a rounded shape and are inside of a sandy siliceous matrix. The layer is cemented, which supposes a necessary mechanical process of disintegration. The sand of the matrix has somewhat of a thick grain and a quartzose nature and has somewhat of a rounded and sub angular shape. The colour of the stratum is yellowish with greyish whitish variations. There is evidence of variable gold contents and according to the results of the analysis we have obtained an average of around 2.5 grs/m3. it is probable that there is free gold inside of the sands that serve as a matrix to the conglomerate, in fine to very fine sizes of grains that cannot be seen with the bare eye, as in the quartz pebbles. According to the existing outcropping a layer of 1,200 meters in length and an inclined height of 120 meters that can be dug into can be seen.
