In 2005, Creighton mine produced an average of 3,755 tons of ore per day on a 6 days per week schedule. 2007 was a breakthrough in mining extraction and exploration, with the conformation of mineralization at depth, [18] which produced 793,000 tonnes of ore with grades of 1.62% copper and 2.8% nickel.
The depth measurements in this list represent the difference in elevation from the entrance of the mine to the deepest excavated point. The definition of mine for this list is an artificially made excavation for the purpose of extracting resources, that can potentially be accessed by humans.
The biggest display is a thirties-forty-era Watt Car located in the centerpiece of the lobby area. It was donated to the museum by the Cravat Coal Company. It stands in front of a huge photo of the entrance to a deep mine. The museum's walls and ceiling are set in black to give the underground feel of a deep mine.

SNOLAB is a Canadian underground science laboratory specializing in neutrino and dark matter physics. Located 2 km below the surface in Vale's Creighton nickel mine near Sudbury, Ontario, SNOLAB is an expansion of the existing facilities constructed for the original Sudbury Neutrino Observatory (SNO) solar neutrino experiment.
The Creighton fault as it passes under Science North. Creighton fault is a major fault line through the Sudbury Basin in Canada. It has a mapped length of 56 km, a throw of over 600m, and a shear zone 30m wide, and runs east–west through Lake Ramsey and the Creighton mine.
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. This process is considered to be safer compared to underground mining because the coal seams are ...
