Dec 07, 2005 (A Wilson) - The Godon Lake Iron Range extends south from the axial planar fault along Evans Creek between Pashoskoota and Rainbow Lakes to a position approximtely 400 m east of Godon Lake where it is faulted and cut of by a diabase dike. To the north the iron range merges with the South Evans Creek Iron Range and to the south the faulted extension is the Reynolds Iron Range. The iron range is cut by a number of minor left lateral faults.

Dec 07, 2005 (A Wilson) - The iron formation has been described as a brecciated bands of silica within a siderite matrix. It is observed to be more siderite-rich on the east side, and more silica-rich on the west side. On the east side of the iron formation the rocks consist of intermediate to felsic metavolcanics comprising sericite schist and massive units. On the west side, the rocks are intermediate to mafic metavolcanics consisting of massive and tuffaceous units.

Dec 07, 2005 (A Wilson) - The average composition of the iron formation was estimated to be 30.7% Fe and 21.9% Si (1953). Other analyses indicate that the iron range has a composition ranging from 13.99% Fe and 64.09% Si to 19.06% Fe and 50.23% Si.
