Production Start...
Mine Life6.73 years (as of Jan 1, 2020)
There was no gold production from Cam & Motor mine during the year which was a carry forward from prior year as the mine continued with the construction of its BIOX Plant Project throughout the year.

The commissioning of the BIOX Plant was completed on 14 April 2022. Production is forecast to improve as Cam & Motor returns to producing from its high grade pits. The Plant is expected to reach full capacity production from Q3 2022.

2. Most productive gold belt (>400 tonnes Au mined to date) in Zimbabwe and stretches for 150km with average width of 50km (altitude varies from 900-1300m above sea level.

3. Stretches from Kwekwe to Kadoma, touching the Gweru greenstone belt to the south and the Chegutu greenstone belt to the north.

Midlands Greenstone Belt General Geology.
Comprises of the following Litho-stratigraphic units:
a) Rhodesdale Granitoid Gneiss Complex;
b) Greenstone Belt Metavolcanics lithologies (Bulawayan);
