Here's another write on the story:

Apparently the objects will be donated to a Holocost museum in Argentina.
There were antiquity objects found in the cache. The discovery was related to an Interpol program on trafficking in illicit objects called "Operation Far East":

BTW, the hidden room apparently had an exterior window...
There were stories of submarines carrying 3rd Reich officials and treasure to Argentina's coast at the end of the war. I suppose that the only way to authenticate this stuff would be contemporary photographs showing objects.
