As a family business passed on down through the generations the Cox-Mannion connection would be one of the longest surviving drilling families in Australia. It is now into the 4th generation with Jason Mannion, and the 5th generation is a high chance as Jason and Jacinta's only son Mitchell (7) was visiting his first drill site at 5 months of age and every chance he gets.

since the age of about 3yrs he's been helping Jason drill water bores in the middle of summer all over the Northwest, NSW. Charles Cox, born in 1888 was a driller first on the Darling Downs and then moving into northern NSW. He started drilling with steam driven early model Southern Cross rigs almost 100 years ago.
