Some signs of geological structure indicate that cracks and / or shifts are east-west-
directed and in accordance with regional geological maps
Geological interpretation is based on the results of field observations :
Trachyte is deposited in a submarine environment
Trachyte Volcanism penetrated the Tonasa Formation in the late Miocene
Intrusion is accompanied by the activity of tufa, lava and carbonate sediment deposition.
Trachyte volcanism under the sea is conducive to the deposition of Pb-Cu
It is possible that a regional fault caused the Tonasa Formation to appear again in the east. This regional fault is only expected but may be parallel with the main north-south trending regional fault shown on the map
The primary metal is lead but it also contains significant silver and some presence of copper, zinc.
