Reef Boring Technology
To accurately drill and ream holes on reef in narrow tabular ore bodies typically found in the South African Gold and Platinum mines.
By doing it this way there is no need for the blasting of rock with explosives which means that mining can take place 24/7. People are not exposed to high risk areas (on the face) and roof support and scraper cleaning are not required.
Dilution is minimized due to only the reef being extracted.
