Hi Robbin
The following I got from “A complete guide to the snakes of South Africa” by Johan Marias:
“A large, powerful constrictor with a pointed snout and a small head very well adapted for its burrowing existence. It spends most of its time underground in search of food. Here it pushes its way through soft sand in search of moles and other rodents. Its prey is usually seized by the head and constricted.”
“The Mole Sake, although not venomous, can be quite vicious when threatened and will hiss and lunge forward with its mouth agape”
But this doesn’t mean all Mole Snakes will always do it. We have had an encounter with a boomslang that was supposed to be shy but forgot to read the book.

We had a Moz spitting cobra that wasn’t suppose to have the habit of standing his ground - ours was lying on the veranda as if it belonged to him.
The only reason why you should think about relocating the snake is the following:
“Unfortunately, this
useful snake is often mistaken for a cobra or mamba and is usually killed on sight”
Other info on this snake:
“Food and Feeding:
Adults feed on rats, moles, gerbils and other small land mammals. Birds and nestlings are taken, as are eggs, which are swallowed whole. Juveniles feed largely on lizards”
“Danger to man:
Not considered harmful, but large adults may inflict a painful bite”
It would however still be nice to get more info on this snake from people like Pilane
