1950-1952: Falconbridge drilling east of the Onaping mine intersected Ni-Cu mineralization. In the 1960s, 2 hangingwall drifts were driven from the Onaping mine shaft to allow underground drilling. Between 1972 and 1981, nine ore zones were delineated. 1985-1990: the Craig mine was in initial development; 1991-1994: in development and producing some ore; 1995-2009 the Craig mine was in full production. Production ceased in 2009. In 2012 KGHM began using the Craig Mine shaft and infrastructure to access the Morrison deposit.

Aug 20, 2015 (L Hall) - The Craig Mine is a SIC Contact deposit hosted by Sublayer Breccia and Footwall Breccia in contact with Archean Levack Gneiss in the Levack Embayment of the North Range of the Sudbury Structure.
Aug 20, 2015 (L Hall) - Sublayer Breccia is a fragmental rock with an igneous textured noritic groundmass bearing inclusions of mafic and ultramafic character of contentious origin. The Footwall Breccia has an igneous groundmass; however it is more felsic tending towards granitic composition. The inclusions in Footwall Breccia are derived from the footwall rocks, in this case primarily Levack Gneiss.
