Terramin Australia’s Angas Zinc Mine is a finalist in the 5th Annual Australian Mining Prospect Awards for using innovation to overcome a wall of clay and silt.

The mine employed a civil construction approach to tunnel excavation in order to combat the problem. The mine used a drilling jumbo to erect initial roof support, and cautiously dug out the face in two stages. As hard rock appeared in the decline floor, and then increasingly became part of the advancing face, the material had to be broken in a way that wouldn’t shake up the silt too much.

Angas is expected to produce up to 65,000 tonne of zinc and 24,000 tonne of copper-lead concentrate annually when in full production.
