| Summary | (Plain Language Summary, not published)
The Lalor deposit located in northern Manitoba represents an imporatnte resource of base metals (Cu, Zn and Pb) but also of precious metals (gold and
silver). The significant amount of gold contained in this deposit is unusual when compared with other deposits of similar type. This makes this deposit particularly economically important but also scientifically interesting: the study of this deposit
and its geologic environment aims at better understand the mechanisms responsible for the gold enrichment. The preliminary results presented in this document allow differentiating the principal volcanic units present in the deposit footwall (below
the ore horizon). The characterization of the volcanic units in terms of chemical composition helps illustrate their distribution and then define the environment in which the deposit was formed, an essential component of the study of this important
deposit. |
