- The magnetite ore body was discovered in 1948 by a government aeromagnetic survey, and the stripping of 120 feet of limestone overburden started in 1953. - The first shipment of iron ore pellets commenced in 1955, and eventually the mine employed 300 workers and support staff. - Size of the pit: 2800 feet long, 1500 feet wide covering 75 acres with a depth of 550 feet. The average grade of the circular haulage road was 10%. - There has been a total of 70 million tons of waste rock removed from the pit to date...and at the time, 2 ~ 250 HP pumps were needed to pump excess water from the pit for excavations to continue. - The breakup of the rock and ore was accomplished with sets of drilling patterns boring 7 inch holes 60 feet into the bedrock, and filled with 8 - 32, 000 lbs of explosive. Each blast could yield 20 - 80,000 tons of rock and ore. - Electric shovels used - 3 with 6 cu. yd. dipper, 1 with an 11 cu. yd. dipper....Dumptrucks used - 6 ~ 105 ton with 1000 HP diesel electric drive, 2 ~ 55 ton with 635 HP diesel engines. - Total mine production: 1.3 million tons of iron ore / 3.5 million tons of waste rock. - Process: The iron ore containing magnetite is crushed and ground, magnetically separated to produce 65% iron concentrate, then converted by roasting into hematite pellets ( 3 crushers of 350 HP each, 2 rod mill grinders of 350 HP each and 2 ball mills). - The 2400 degree F. roasting took place in 4 vertical shaft furnaces 6 X 12 feet and 40 feet high. - Annual plant production: 520,000 tons of hematite. - A daily ore train of 30 to 35 cars took pellets south to Picton port for loading into the 25,000 ton ore boats.
