those are both from Thaumcraft, and are shown in the thaumonomicon.
Treasure acts in the same way as Fortune with the wand of excavation or wand of equal trade.
and Frugal acts in the same way as Unbreaking with any wands.

If I remember correctly, both of those enchantments can be put on the wand of excavation. Treasure makes certain ores drop more items (kind of like fortune for vanilla tools) and frugal lowers the durability used on the casting wands while in use (Wand of excavation, wand of fire, wand of frost etc.) You can check your thauminomicon for details on them just in case I'm mistaken.
Hope I helped.
Thank you both!
