Andes Gold Corp (AGCZ)

[True Blue]

Those coordinates are from 1956

The centre of the property is located on 654,500 East and 9,594,000 North (UTM PSAD-56, zone 17S) or longitude 79° 36' 31" West and latitude 3° 41' 20" South (Provisional South American 1956 projection).

The mill in this picture isnt next to Andes but they may be mining the same mountain in which case the coordinates would probably be the same.
