I am pretty sure that boldore is not a legendary Pokemon
You have to trade a boldore to have it evolve.
You can find wild Boldore in Chargestone Cave. They are easy to catch because they have the ability Sturdy, which leaves them with 1 HP.
Boldore evolves when you trade it.
I don't think you can just find Gigalith in Pokemon Black.You have to evolve Boldore.
you can find one in the electric cave.... Hope this helps!

Boldore evolves into Gigalith only by trading. So you will have to find someone to trade back and forth with so that he will evolve.
Boldore is #525 in the national pokedex, and it is a Rock type Pokemon.
