In 2011 there was a new development on which is now Rue Paul Doyon in Boucherville, Quebec. The top layer of the bedrock was excavated while installing a new sewer system. The rubble contained small vugs lined with calcite which varied in size from a few millimeters to five centimeters. This locality is roughly five hundred meters west of the old Landreville Quarry.

According to a Supreme Court of Canada ruling, the nature of the quarry in question is a "shale quarry covering forty arpents (1,472,027 sq. ft.) located in an open field approximately three miles from the centre of the Town of Boucherville in the Parish of Sainte-Famille de Boucherville, which was annexed by the Town in 1963." (Supreme Court of Canada, Landreville v. Town of Boucherville, [1978] 2 S.C.R. 801)

June 14, 2012 : Site revisited. Ongoing development of a housing project has extended the work area. A 100-meter retaining wall was built using meter-sized blocks : some limestone blocks are present, but most seem to have been taken from a ground-level igneous sill of a very dark porous rock, containing large portions of well-defined black pyroxene crystals (augite ?). This rock could possibly be pyroxenite, gabbro, or else. A 30-40cm remnant of this sill is still present in the eastern part of the site, and it is covered with some of the shale described above.

On the same day, the nearby Landreville Quarry was visited, but the igneous sill at that location is clearly different. It is described as nepheline syenite in the Deposit File of the MRN (Quebec Province's Department of Natural Resources).
