Underground Contract Mining

The Byrnecut Group engages in mechanised underground mine feasibility, mine development and mine production.

This includes shaft sinking, shotcreting, raise-drilling, the provision of high-quality equipment rebuilds, maintenance engineering, labour hire and training for the mining industry, plus mine engineering consultancy services. Principal customers include first-world mine owners across the globe.

The purpose of a contract miner is to deliver the short-term schedules and targets for the mine and manage all necessary personnel and equipment required to make this happen.
