The following is a link to an article published by La Nacion (Buenos Aires). It is freely accessible during a few days. 30 days after publication, a reader must be registered (not subscribed) to read it. It describes a strange case of a gold and silver laden vessel that went down under mysterious circumstances, off the coast of southern Argentina. Let us remember that it is summer at this time of the year in Argentina and Chile. The vessel cannot be accessed legally without a special permit from certain Argentine authorities. The crew and passengers were rescued by the Argentine navy. The load presumably will be recovered, together with the vessel. Another strange point is the line of logistics that said shipment was following. Its final stated destination was a point in Switzerland, for refining. It was supposed to be sent from Santiago to a Swiss gold and silver refiner. The detail is, the movement of gold and silver from Santa Cruz may be easier (avoiding Cape Horn or the Straits of Magellan) following a line from Santa Cruz to Buenos Aires (overland) and from Buenos Aires (by airfreight, if you will) to any Swiss gold and silver refiner.
Have a nice day.
