Preliminary observations on the geological environment of the Paleoproterozoic auriferous volcanogenic massive sulphide deposit of Lalor, Snow Lake, Manitoba / A. Caté, P. Mercier-Langevin, P.-S. Ross,... : M183-2/7372E-PDF

"The Lalor auriferous VMS deposit in the Proterozoic Flin Flon‐Snow Lake belt of Manitoba is a recent deep (>500 m) discovery by HudBay Minerals that is currently being developed for commercial production. It contains approximately 27 Mt of ore potentially including 75 t of Au as well as 684 t of Ag, 1.38 Mt of Zn and 0.2 Mt of Cu. This deposit is an ideal “natural laboratory” to better understand the signature and key characteristics of auriferous VMS deposits and elucidate characteristics that can be used to vector toward them (Mercier‐Langevin et al., 2012). The deposit is situated in the Flin Flon greenstone belt which is part of the Paleoproterozoic Trans‐Hudson orogen. Lalor has been affected by several hydrothermal events, an intense polyphase deformation and an amphibolite grade metamorphism"--page 3.
