There appears to be no formal copyright record for She Gods according to the US Copyright Catalog for Motion Pictures, 1950-1959. Therefore, I believe that this movie is all or partly in the public domain.
Archive.org also lists She Gods of Shark Reef as public domain with the Creative Commons attribute.
