I happened to catch the trailer for this film on the Punisher:War Zone DVD and I have to say it looks pretty good. There's also a very good article on the Burrowers in the April edition of Fangoria.
In this horror Western, a band of courageous men set out to find and recover a family of settlers that has mysteriously vanished from their home. Expecting the offenders to be a band of fierce natives, the group prepares for a routine battle. But they soon discover that the real enemy stalks them from below.
Doug Hutchison, Clancy Brown, William Mapother and Sean Patrick Thomas star.
