South African photographer Dillon Marsh combines photography with computer-generated images of material extracted from the landscape he portrays. In the series For What It’s Worth, the artist visits former copper, diamond, gold, and platinum group metal mines that are now scars on the landscape to create salient visualisation of extraction. 

The Palabora mine, pictured above, is almost 2 km wide and over 800 m deep. 4.1 million tonnes of copper have been mined here, but this total is dwarfed by the massive hole left behind.
