The McFauld's VMS occurrences consist primarily of stringer copper-style mineralization associated with intense talc-chlorite alteration. The alteration at McFauld's is very similar to that observed in stringer zones in the Matagami Lake and Noranda districts, Quebec. Its intensity and the high copper contents in the McFauld's occurrences attests to these having formed from a series of well-focussed, high-temperature systems. Such stringer systems typically have associated, but structurally separated zinc zones. Searching for these, as well as additional copper mineralization will be a priority of the next round of geophysical surveying and drilling.
