Anorthosite suites in these corridors are younger than 1.2 Ga and formed in distinct age ranges: the larger bodies (e.g., Lac St Jean, Lac Fournier – Attikonak, and parts of Havre-Saint-Pierre) are late pre-Grenvillian in age (1160–1120 Ma), whereas most smaller bodies (which occur mainly in the western corridor) and the Lac Allard portion ...

Two localities associated with massif-type anorthosite are known for their rutile–ilmenite associations: several occurrences in the Saint-Urbain anorthosite, and the Big Island ore deposit in the Havre Saint-Pierre anorthosite (Warren, 1912, Morisset and Scoates, 2008, Morisset et …

The granite of the dimension-stone industry along with truly granitic rock also includes gneiss, gabbro, anorthosite and even some sedimentary rocks. Natural stone is used as architectural stone (construction, flooring, cladding, counter tops, curbing, etc.) and as raw block and monument stone for the funerary trade.

The deposit is hosted by anorthosite in the Havre-Saint-Pierre anorthositic suite in the Grenville Province. The mine is 43 kilometres north of the port of Havre-Saint-Pierre on the Gulf of Saint Lawrence.
