Point Location Description: Limestone exposure extends along both banks of river; point at mid-rapids on north bank.
Location Method: Data Compilation
Access Description: By river, approximately 110 miles north of Mattagami railway station. Via Coral Rapids: from mileage 96 on the Moosonee branch of the Ontario Northland Railway, a 14-mile long winter road runs diagonally across Kilmer Twp. to Mattagami R. Or, from ONR mileage 112, an old road ran westward to an old lumber camp on the Onakawana R. This road was apparently extended by Dewson Mines in 1949 to access their drill site on the Mattagami on the south bank of the river, just west of the iron ore zone at the head of Grand Rapids. (1949, AF T-405).

Mar 20, 2014 (D Draper) - Rocks comprising the Abitibi River formation of Middle Devonian limestone outcrop on several rivers within the Moose River Basin area, the best exposure being at Grand Rapids on the Mattagami River. Here the formation forms cliffs rising in places to a height of 50 feet above low water level and extending the length of the rapids for a distance of two miles along both banks of the river.

Mar 20, 2014 (D Draper) - The section of Abitibi River limestone found at Grand Rapids consists of 8 feet of uniformly bedded grey limestone containing crinoid columns followed by 40 feet of rather massive cavernous grey limestone, somewhat irregularly bedded, which weathers on exposure to a grey or buff colour. The upper 40 feet is very fossiliferous.
Mar 20, 2014 (D Draper) - Analyses of a sample of grey magnesian limestone, from the west bank at Grand Rapids, including all beds in a 25-foot cliff returned 86.43% of CaCO3, and 10.94% MgCO3
