The Malachite Pup zone extends 400 meters horizontally, between 1000 and 1400 meters elevation. Intermediate tuffs and argillites, intruded by andesite and lamprophyre dikes, are very weakly and contain 3 to 5 per cent disseminated pyrite.

Mineralization is both disseminated and within discrete quartz veins. In the first type, 1 to 7 per cent pyrite and 1 to 2 per cent chalcopyrite form blebs and disseminations within altered volcanics. Grab sample 459562, which was taken across one meter of this material from within a twenty meter patch of heavy malachite staining, assayed 1.23 gram per tonne gold with 2.05 per cent copper (Assessment Report 22151). The second type of mineralization consists of quartz veins with up to 5 per cent pyrite and 1 per cent chalcopyrite. The quartz veins are generally 2 to 30 centimetres in width and up to five meters in length. A small outcrop of a felsic intrusive body, several meters square and containing up to 1 per cent disseminated chalcopyrite, outcrops just below the Malachite zone. Silver, lead and zinc values are relatively low for all Malachite zone samples.
