Field Trip Report
Université Laval / INRS-ETE SEG Student Chapter
Local field trip report for 2013-2014
Student in charge of local field trips: Fanny MacMurray-Pinard
Excursion at the Montauban mine (September 21st, 2014)
Montauban is a Zn-rich VMS deposit that has been exploited from 1910 to the 1960s including several gold-rich zones. The deposit is hosted in highly deformed volcanic rocks metamorphosed to the upper amphibolite grade. Part of the deposit is observable on outcrops and a section from the altered footwall to unaltered basalts in the hanging wall has been visited by a group of six student from the Université
Laval and the INRS-ETE. Antoine Caté, Ph.D. student on a metamorphosed VMS deposit lead the tour.
Students have observed a typical section through a tilted VMS deposit with the unusual mineral assemblages due to the high-grade metamorphism (anthophyllite, grossular, tremolite, sillimanite, calcsilcates…), as well as porphyroblastic sulphides (sphalerite and pyrite). The field trip allowed students to observe the effect of metamorphism on hydrothermal alteration mineral assemblages and to document the geometry of a VMS deposit.

Visit of COREM installations in Quebec City (Friday January 17, 2014)
A group of 4 students went to visit the COREM installations, which is a research consortium for mineral treatment and metallurgy techniques. The visit was leaded by Jean-François Wilhelmy, Extractive
Mineralogy Researcher, to learn about different physical and chemical methods used in the industry. The group visited the pilot factory, which demonstrates several of these processes. The students were also introduced to the MLA (Mineral Liberation Analyser), a new device that can precisely and rapidly quantify minerals in concentrate samples.
Visit of Niobec Mine in Saint-Honoré (Wednesday March 19th, 2014)
The visit was leaded by Marc Lavoie, Geology Technician, and Jean-François Dorion, Exploration
