Deposit Type

  • VMS


Summary:

The San Nicolás volcanogenic massive sulfide (VHMS) deposit was discovered by Teck in November of 1997 through geological mapping, geophysical surveys and drilling. Drilling on the property has intersected two massive sulphide deposits, the largest of which is San Nicolás that is divided into upper and lower zones. Additional base metal mineralization and alteration has been identified elsewhere on the property.

Mineralization is hosted in volcaniclastic rhyolite, flanking flows and breccias of a flow-dome complex. Mafic flows, sills and dykes dominate the footwall lithologies. Alteration consists of common calcite stringers, Fe-carbonate and barite in the footwall with localized intense chlorite plus quartz-sericite alteration of the felsic and mafic host rocks.

The upper sulphide zone (Cap Zone) is dominated by finegrained pyrite with high concentrations of sphalerite and chalcopyrite that range from massive to semi-massive to laminated and strongly brecciated. The lower sulphide zone (Feeder Zone) is dominated by finegrained pyrite and chalcopyrite with local sphalerite.

Mineralization is generally massive to semi-massive sulphide with well-developed sulphide stringers developed below and lateral to the massive sulphide.
