Older plutonic phases consist of granite, granodiorite, and tonalite. A highly evolved younger phase is enriched in U, Th, Rb, F, B and Li it therefore appears to be of midplate origins similar to early Tertiary intrusions in interior Alaska. A propylitic alteration assemblage, widespread in the older plutonic
form gold bearing alteration haloes around the shear zones. Hydrothermal replacement deposits are formed when hot aqueous solutions react with and replace the host rock. Figure 4 Alluvial Deposits Alluvial deposits consist of hydrodynamically accumulated gold by streams and lakes. They occur on the surface, just below the surface or deeply buried.
The discovery hole tested a prospecting find loed approximately 10 km west of the Conrad, Osiris, Isis, Isis East gold zones in a new area not previously drill tested. This new gold zone has been named Anubis. News release highlights: First diamond drill hole at Anubis (AN12001) intersects 8.51 metres of 19.85 g/t gold

Primary sparry carbonate cement, mainly ferroan calcite is characteristic features of both S1 and S2 units. Marl lies conformably over the S2 unit, and the andesitic sill intruded it. Gold mineralization is principally stratabound, loed along two stratigraphic contacts. The contact zone between units S1 and S2 is a major mineralized horizon.

Based on the geologic logging and assays received to date from these new drill holes and the results of the Phase 1 program, NGE believes that it has defined a large blanket of silicifiion at South Grass Valley, with a strike length of more than three kilometres, that is consistent both in terms of size and architecture with the zones of
The Hay Gully, Major Creek, Duck Creek and Yeates Creek areas are generally cleared for grazing and agriculture. Riparian zones are poorly vegetated, very dry and on hard sediments. Flow during the wet seasons, small weirs to retain some water. Weeds include prickly acacia and rubber vine although there is no distinct riparian zone.
gold mineralisation in this large system has identified several high priority drilling targets. •Potential target model of several satellite mineralised zones of up to 100,000 ounces Au along the mineralised structures within the field, with a global target of hosting >1M oz.

alteration to pyritequartzmuscovite greisen, with minor chalcopyrite and molybdenite. Greisen also occurs at Giles Nob (about 13 km ENE of Blue Rose) and as narrow veins at Blue Rose. Weathered granitic rocks outcrop on the S side of the major creek in the SE corner of the prospect. It is uncertain whether this outcrop is part of the main
extensive sheeted quartzsulphide vein and stockwork zones with phyllic alteration envelopes within and around a complex of microgranite intrusives (Figure 3). Alteration and mineralization at Leichardt Creek occurs over a substantial area. The Leichardt Creek mineralised zone extends along a NESW trend and has been broadly
Siwash Creek is the next major creek west of North Trout Creek and has several exploration with the goal of finding the source of the placer gold within lode deposits. There are no known mineral resources or reserves on the property, although there are several Zones of alteration were found, but with very sparse mineralization.
The strata are based on major lifehistory characteristics (e.g., species runtypes) and ecological zones. The upper Willamette River chinook ESU consists of a single stratum as it consists of a single runtype (springrun fish) that spawns within a single ecological zone (the Willamette River).
SUMMARY The 930 square kilometre Twangiza Property is loed in the South Kivu Province of the Democratic Republic of the Congo (DRC), 35 kilometres west of the Burundi border and 150 kilometres to the south of Goma. The Twangiza Property is loed in the northern half of the Great Lakes subprovince of High Africa, one of the world''s principal Precambrian orogenicmetallogenic provinces.
