The Bone Snatcher

The Bone Snatcher is a 2003 British-Canadian horror film directed by Jason Wolfsohn and starring Scott Bairstow, Rachel Shelley, and Adrienne Pearce.

[1] When workers begin disappearing in a Namibian mine, Dr. Zack Straker and a search team are sent into the desert to find out why the geologists of a diamond expedition have lost radio contact.

They arrive at the scientist's camp in the desert, but soon find the neatly gnawed bones of their colleagues and a trail that leads them to a strange rock formation.

A game of cat and mouse continues through the desert, with the team being slowly picked off and the bug and bone monster eventually being chased down in a derelict mine.

Suddenly, the derelict mine structure starts to fall down, leaving Zack and Mikki to run back to the truck - where they find they are now the only survivors of the team.
