QUEBEC Toronto-based ALEXIS MINERALS has drilled a volcanogenic massive to semi-massive sulphide (VMS) zone that includes a copper-rich stringer zone adjacent to the former Louvicourt base metal mine in Val d’Or. Core from a wedged hole assayed 3.60% Cu over 9.40 metres including 6.81% Cu over 3.45 metres.
Alexis is hopeful that this discovery marks the leading edge of deposit even larger than the mined-out Louvicourt deposit. The new zone exhibits several classical styles of mineralization in a typical VMS environment, according to the company. Sulphide mineralization grades upwards from a Cu-rich stringer and alteration zone into a massive sulphide horizon located within the extension of the productive Louvicourt mine sequence and associated with volcaniclastic sediments typical of the Louvicourt mine. Sulphides are dominantly chalcopyrite, pyrite and pyrrhotite. Assay results for zinc, silver and gold, metals commonly associated in a VMS system, are low, however those reported are very similar to those associated with chalcopyrite- and pyrrhotite-rich areas of the Louvicourt deposit.
Intense chlorite alteration with disseminated sulphide mineralization persists well above the new VMS discovery. This hanging wall alteration is locally characterized by coarse garnet with magnetite alteration mineralogy, more intense than that encountered lower in the stratigraphy. Alexis thinks this may suggest potential for a stacked VMS system with additional potential for sulphide occurrences higher in the stratigraphy and in the untested area to the south of the new zone.
