Caland Opens New Iron Ore Reserves with Hydraulic Slurry System

Application of an hydraulic mining system to a troublesome overburden removal project has unlocked an estimated three million tons of ore reserves at Caland Ore Co., Ltd.'s open-pit iron operation in Ontario, Canada. The mine, operated by Caland under a 99-year lease and royalty agreement with Steep Rock Iron Mines, Ltd., would have been forced to curtail its mining operations later this year as the economic limits of the original pit design were being reached. As a result of the stripping program, which uses a tandem set of Marconaflo jet slurry systems, Caland officials now estimate that mining will continue into 1977. These reserves, added to existing ore stockpiles, are expected to sustain the firm's pelletizing operation well into 1981. In addition, Caland engineers are initiating studies to continue mining since the ore body, to date, has yet to bottom out.
