This active five-level quarry has been in operation since 1961. As of 2012, it spans some 850 meters in length, a width of 350 to 750 meters, and a depth of roughly 50 meters.
The following description is taken from the Deposit File of the MRNF (Ministère des ressources naturelles et de la faune):
The main rock type is a very fine-grained, pale medium-grey, siliceous dolostone, in generally thick beds and marked at places with fine clay laminae.
This rock is irregularly interstratified with a dark grey, fine-grained dolostone, in thin beds separated by thin interbeds of shale, and by thick beds of fine grained, medium dark grey dolostone dotted with small cavities filled with white crystalline dolomite.
These strata are assigned to the Beauharnois Formation of the Beekmantown Group.
Mineralogy is typical for similar quarries in the region, and excellent dolomite, calcite and quartz specimens are notable.
