Technical Specialist's Report<br />

Within the Mt Boppy pit, the Main Lode is a quartz vein developed al<strong>on</strong>g a normal west-dipping fault. The<br />

Main Lode strikes approximately north-south and dips at approximately 80º west; however it shows<br />

c<strong>on</strong>siderable variati<strong>on</strong> in strike and dip. These variati<strong>on</strong>s appear to be associated <strong>with</strong> gold mineralisati<strong>on</strong><br />

development in the wall rock to the lode. The best mineralisati<strong>on</strong> in the wall rocks occurs <strong>with</strong>in the<br />

Baledmund Formati<strong>on</strong> rocks <strong>on</strong> the western side <strong>of</strong> the Main Lode where the lode has a shallower dip.<br />

At the northern end <strong>of</strong> the pit, the Main Lode is truncated at an acute angle by the West Lode fault. The fault<br />

dips to the east and displaces the Girilamb<strong>on</strong>e Group phyllite <strong>on</strong> its western side against the Baledmund<br />

Formati<strong>on</strong> sericitic siltst<strong>on</strong>e <strong>on</strong> its eastern side. The West Lode is about 1 m to 2 m wide and is largely a fault<br />

breccia clasts <strong>of</strong> phyllite, sericitic siltst<strong>on</strong>e and quartz.<br />

The mineralisati<strong>on</strong> at Mt Boppy is hosted by brecciated and silicified fine-grained sediments and quartz<br />

veins. The gold mineralisati<strong>on</strong> c<strong>on</strong>tains minor zinc, copper and lead. Minor carb<strong>on</strong>ate, siderite and dolomite<br />

alterati<strong>on</strong> is associated <strong>with</strong> the mineralisati<strong>on</strong>.<br />

Drilling at Mt Boppy has been carried out in a number <strong>of</strong> campaigns and c<strong>on</strong>sists <strong>of</strong> percussi<strong>on</strong>, RC and<br />

diam<strong>on</strong>d drilling in additi<strong>on</strong> to blast hole drilling in the previously mined open pit. <strong>Polymetals</strong> completed the<br />

most recent drilling programme in 2011 <strong>with</strong> seven RC drillholes and 18 diam<strong>on</strong>d drillholes completed.<br />

Drillhole collars were surveyed and downhole surveys completed. Drillhole collars from older drilling<br />

programmes were resurveyed. Drill cuttings and core were geologically logged and drill logs are available for<br />

older drillholes.<br />

Samples were analysed for gold by fire assay <strong>with</strong> AAS finish. The recent programme was supported by<br />

assay quality c<strong>on</strong>trol protocols.<br />

The resource estimate is based <strong>on</strong> interpretati<strong>on</strong> <strong>of</strong> four geological domains (Figure 3.3):<br />

• Historical stopes.<br />

• Low-grade mineralisati<strong>on</strong> <strong>on</strong> the footwall <strong>of</strong> the Main Lode structure.<br />

• High-grade mineralisati<strong>on</strong> immediately adjacent to the Main Lode structure <strong>on</strong> the hangingwall.<br />

• Low-grade mineralisati<strong>on</strong> <strong>on</strong> the hangingwall to the main lode structure and the high-grade domain.<br />
