Located in northeast Washington State, this gold mine utilizes a Thiessen Tornado CRF (cement rock fill) plant underground. Located near the mine portal, this plant features a high shear colloidal mixer and is capable of running unattended when activated remotely. This system, developed by Team Mixing Technologies is totally self-cleaning and is controlled by a Modicon PLC and touchscreen.

This plant features an automated dust collecting system. A 110 ton cement storage silo, located on the surface automatically refills the underground silo when required. A feeder and cement blower is utilized for pneumatic conveying of cement.

Following the successful service at the Lamefoot mine, the plant was relocated to the nearby K2 minesite.
