Amok Ltd. /Cluff Mining operates a uranium mine at Cluff Lake in northern Saskatchewan. The project consists of one open pit and one underground mining operation along with a full-scale milling installation. The underground sloping operations are of the narrow vein type and are done between two levels 50 m apart. The mining method is undercut with concrete backfilling. Cuts are 3.5 m in height and can be as narrow as 1.4 m in width. Sloping operations are mechanized utilizing a CT-500E electric Microscoop marketed in Canada by Teledyne. The machine is only 85 cm in width and does all the mucking in slopes. Ore passes are provided in slope roughly every 40 m to 50 m. This paper describes the utilization of the CT-500E Microscoop in the company's underground operations and provides performance data related to the experience.
