[FTB Continuum] Aluminum ore is weirdly rare : feedthebeast
IIRC, digging around 48 gave me enough aluminum to complete my cast collection without using any gold. (I do NOT recommend using gold for casts, since you are going to need gold gears and circuits for some early quests.) FWIW, I think the rarity is intentional. Bauxite is much more common, but requires more processing to become an alumin(i)um ...
