There has been speculation that NWA 011 may be from either Mercury or Venus.
But it is just speculation, and it is most than likely to be from an
asteroid.

Quoting from the link you just provided:

"The material from which NWA 011 originated may have been like some
 CH or CB chondrites, members of the CR chondrite clan, which are all
 related through oxygen isotopic compositions. The NWA 011 parent body
 is probably of asteroidal origin, possibly the basaltic asteroid
 1459 Magnya."
