The whole of Japan is now Irving's Oysterone thing that seems to be missed in the deal with Newmont, is that Irving with Newmont is now willing and capable of exploring and exploiting any gold/silver mining possibilities in Japan.
From the Cedar filing:
the formation of an alliance between Irving, its Japanese subsidiary and Newmont Exploration Pty Ltd. (“Newmont Goldcorp Australia”), whereby the parties will work together to identify and, if designated by Newmont Goldcorp Australia, jointly exploit mineral exploration opportunities throughout Japan (the “Alliance”).
