The Niagara occurrence is part of the Iron Range showings, located near the crest of the ridge that is west of and parallel to the south flowing portion of the Goat River. The location is centred on a showing of hematite-bearing igneous rocks on the eastern slope of the ridge, south of Six Mile Creek and north of Highway 3.

The regional geology, deposit description and local geology for this occurence is similar to that of the American Flag occurrence (082FSE016) which lies approximately 8 kilometres to the north.

Iron mineralization occurs as hematite within gabbroic sills and dikes of the Middle Proterozoic Moyie intrusions. This zone is hosted in the Middle Proterozoic Middle Aldridge Formation along the north trending, subvertical Iron Range fault zone. The Aldridge Formation in the vicinity of the showings consists of well bedded quartzofeldspathic wacke, laminated siltstone and quartzite.

The area has been explored since the late 1890’s and a completed regional exploration history can be found at the O-Ray (MINFILE 082FSE017) occurrence.
