The Hutti Gold deposit has been divided into three parts by intrusion of two major dykes. The central part, bound by two dykes in North and South, is present operating area of Hutti Gold Mine. Part of the deposit lying south of the southern dyke is called Hutti South Block. Extensive surface exploration by way of trenching, followed by surface diamond drilling has been carried out with encouraging result, in terms of reserve, as well as grade of the deposit. With a view of detailed exploration, underground mine development was taken up in the year 1983-85. The activity was continued with further exploration by sinking South Shaft up to a depth of 169.90 m i.e. 5th level and occurrence of all the reefs was confirmed by exploratory underground development through South Shaft. To continue the process, the proposal for deepening of South Shaft followed by opening of more levels is underway.
