Hill 99 Copper-Zinc-Gold Project

The Hill 99 Prospect, located near the southern shores of Macquarie Harbour was identified by Pacific-Nevada Mining Pty Ltd in 1999 after a reconnaissance sampling programme located an outcrop of massive pyrite-quartz mineralisation.  A subsequent soil sample campaign identified a copper-zinc and gold anomalous (150-511ppm Cu and 150-684ppm Zn and up to 92 ppb Au) zone extending inland along strike from the coastal pyrite-quartz mineralisation. A single panned concentrate stream sample returned 5.1 g/t Au.

A subsequent gradient array Induced Polarisation Survey carried out over the Hill 99 grid identified a linear, moderate conductivity high coincident with the copper-zinc-gold anomalous soil zone. Limited historical drilling has identified intense alteration comparable to that seen around other Volcanic Hosted Massive Sulphide (VHMS) deposits of Tasmania (i.e. Rosebery (Pb-Zn-Ag) and Mt Lyell (Cu-Au)) and returned narrow zones of mineralisation, the best being high grade 30cm massive sulphide zone returning 10.55% copper and 0.244% zinc

Re-processing of detailed airborne electromagnetic (EM) survey data by Sherlock has identified moderate to strong late time conductors close to the known Hill 99 mineralisation. The targets appear to be coincident with the western side of linear magnetic anomaly. Ground EM geophysics are planned to position the targets precisely in the subsurface ahead of drill testing.
