Lord Nels<strong>on</strong> and Lord Henry Geology<br />

The Lord Nels<strong>on</strong> deposit is hosted by a z<strong>on</strong>e <strong>of</strong> intermixed high-magnesium basalt and granodiorite above a<br />

footwall ultramafic unit. A central and an east lode have been defined. Both z<strong>on</strong>es trend north-north-west, dip<br />

approximately -50º to the west and plunge to the south. The central z<strong>on</strong>e is located mainly in the supergene<br />

z<strong>on</strong>e horiz<strong>on</strong>. The east lode is a z<strong>on</strong>e <strong>of</strong> pyrite-silica-biotite-quartz veining that follows the ultramafic footwall<br />

c<strong>on</strong>tact. Gold mineralisati<strong>on</strong> at Lord Henry is dominated by veining. Wall rock alterati<strong>on</strong> is str<strong>on</strong>g but <strong>with</strong><br />

little pyrite.<br />

The Lord Henry deposit is hosted by granodiorite bound to the south and west by a sheared ultramafic<br />

c<strong>on</strong>tact, forming part <strong>of</strong> the Trafalgar shear. Mineralisati<strong>on</strong> comprises a series <strong>of</strong> stacked lodes that dip 20º<br />

to 30º to the north characterised by quartz-sericite-chlorite-pyrite alterati<strong>on</strong>. The overall trend <strong>of</strong> the<br />

mineralised z<strong>on</strong>es is north-east <strong>with</strong> a defined length <strong>of</strong> 400 m. High-grade gold intersecti<strong>on</strong>s are associated<br />

<strong>with</strong> sulphide-rich quartz veins and stringers.<br />

The Two Mile Hill deposit is hosted in a late-stage, near vertical intrusive t<strong>on</strong>alitic stock which cuts the local<br />

stratigraphy <strong>of</strong> mafic volcanics and BIF (Figure 4.5). The stock is about 220 m l<strong>on</strong>g and 70 m wide and is<br />

pervasively altered <strong>with</strong> sericite, silica and carb<strong>on</strong>ate and c<strong>on</strong>tains variable amounts <strong>of</strong> disseminated pyrite.<br />

It also c<strong>on</strong>tains an open-sheeted system <strong>of</strong> quartz veins varying from
