THE OLD GOLD MINE: Our local surfaces owners worked in the past, processing oxidized materials at surface gold veins. Several gold veins were discovered at that time giving information of what they had in the underlying layers. When they found sulfides, the recovery was not satisfactory so, they moved to new veins. The normal depth for that operation was about 2 or 3 metes, with exception for a vein called Leonardo Vein. This vein was mined at 20 meter depth, producing a lot of gold. This gold vein confirmed the mineralization of the concession.
