It doesn't mention adamantium, mithril or stalhrim, nor does it mention silver, gold, copper and brass. We know, however, that all of them are present in Tamriel.
This tree perk doesn't mention the possibility to craft alloys either (although perhaps it will be included in the alchemy perk tree?).
So yes, I am quite disappointed with the missing items of this list. But I am also disappointed with some items that are on this list.
Some perks will allow you to craft Ayleid, Dwemer and Daedric armors. In all the previous games, the Elven, Dwarvish and Daedric arts and crafts have been imbued with mystery. The Daedric techniques seem to rely at least as much on conjuration as it does on smithing.
I really hope that those perks aren't readily available. It would be far more logical if the player had to investigate in Ayleid and Dwemer ruins to unlock them, or to compromise with Daedric artisans.
I also hope that the player will have to discuss with Orcs smiths to unlock the Orcish perk (unless he is an Or him/herself), and that he will be able to discuss with peaceful Goblins, Dreugh, Giants, or any creature provided it's able to craft things, in order to learn its techniques.
I also hope that the fact some materials aren't mentioned on the list doesn't imply that those materials can't be crafted.
Do you also share my concern about the availability of the race-related smithing perks, namely Orcish, Ayleid, Dwemer and Daedric?
