You do not appear to have either a copyright claim or a trademark claim. For a copyright claim, there would have to be copying and this could not occur if the other company never saw your work. Furthermore, short phrases are not protectable by copyright which is multiple books and songs have the same title.
As for trademarks, to be have a claim, there would have to be a likelihood of confusion, which is not the case for a book or movie title relative a mining and metals company. Moreover, without a trademark registration in Mauritius, you would have no trademark rights to enforce there.
