The town has boundaries with Jos Northof Plateau State. It is the gateway to the State’s capital when coming from Zaria, Kaduna State and Kano State as well. Mista-Ali as this land is called in some instances is the adulterated name for Messrs Mc Alley, a mining camp established in 1921 as Messrs Mc Alley & Nicholls. The camp was located in the place we popularly called Office. This adulteration can be attributed to mistakes in the pronunciation of Mc Alley as Mista-Ali or Mr Ali.
