In 2014, the Brucejack Project needed some surface exploration drilling done at the mine site. Due to environmental permitting constraints, they were unable to do this in the traditional method, as all of the necessary water required for a drill program needed to have the cuttings removed before it could be returned to the streams.
As it’s normal to consume approximately 8,000 to 10,000 gallons of water every 24 hours when drilling, one drill would use approximately 1 million gallons of water over the course of a 4-month project. Thankfully, we had just finished testing our Centrifuge Cuttings Management System in Smithers, and offered this unit to Pretivm as a way to proceed with a closed loop water system.
Within a week, the system was set up, operating and able to process all of the drill fluids and remove all of the cuttings. The same drill fluid (2,000 gallons) was used for 4 months, and all cuttings were stored in mega-bags for safe and easy transport.
