LZHole 2, also drilled from southeast to northwest, intersected altered rocks similar to those found in hole 1 in the upper part of the hole and then 34 metres of near solid sulphide between 206.25 and 240.25 metres as well as a second zone of near solid sulphide of 1.25 metres from 248.0 to 249.25 metres. The 34 metre sulphide interval includes a 10.5 metre section of near solid pyrrhotite and chalcopyrite and an 11.75 metre section of near solid pyrite with visible sphalerite. Magnetite occurs both within the pyrite-rich section, and as a discrete layer below the pyrite section. A 2.5 metre chert section occurs below the magnetite layer and above the unmineralized basalt at the end of the hole. This mineral assemblage and its relative position in the core are typical of that found in volcanogenic massive sulphide (VMS) deposits.
