Operator Adam Ladouceur is guiding an electric jumbo drill at Goldcorp’s Borden underground gold mine project, in Canada, which is dispensing with the use of diesel-powered equipment. This quiet battery-powered tunnelling machine is making its way towards gold without lowering air quality. Near Chapleau, north-west of Toronto, in Ontario, Borden is reportedly the first underground mine in Canada to replace all diesel mobile equipment with battery-electric vehicles.
