Columbina Rural Service Center is a populated place in Zhombe. It is 95 km northwest of Kwekwe and 67 km southwest of Kadoma.
The Center is near the now defunct Empress Nickel Mine which is about 4 km to the South-west. Blue Gum mine is on the Gokwe side of Ngondoma River yet this place was the original Blue Gum according to all maps before 1980. Blue Gum was right at the Samambwa Zhombe East Road turn-off here at Columbina RSC. Search engines always point to this place as Blue Gum, Zimbabwe. Columbina Rural Service Center is in Mahogo Village,
