Mungu Discovery

Demonstrated Discovery Potential

The Mungu gold and silver discovery is located immediately northeast of the current resource at the ATO Project. It is a structurally controlled epithermal gold-silver system with localized bonanza grades. The high-grade gold-silver mineralization in the northern part of ATO Pipe #4 has been interpreted by Steppe Gold to have a steeply westward dipping structural control with a similar northeast strike projecting toward and possibly joining the Mungu zone of mineralization.
