Mount Wellington, Victoria
(100% GOLDSEARCH)
The Mount Wellington project is located 20 kilometres south-east of the town of Jamieson and 25km north east of the Woods Point gold mining centre in eastern Victoria. The project consists of granted EL4843, EL5046, El4976 and application ELA5232 which cover a combined 384 km2 of State Forrest.
Local Landscape
Tricky Access
Mike’s Bluff
The project area covers the majority of a belt of well mineralised and, in places, pervasively altered Cambrian-aged calc-alkaline volcanic rocks. The Cambrian age volcanics are composed principally of intermediate to felsic volcanics and sediments interpreted to be deposited in an island arc environment. These rocks have been tentatively correlated with the highly prospective Mount Read Volcanics of western Tasmania and represent some of the oldest known rocks in Victoria. The volcanic rocks are overlain by a sequence of Silurian and Devonian sediments.
Detailed geological mapping identified a number of diorite dykes which cross-cut the Cambrian sequence and are undeformed and unaltered and therefore interpreted to possibly be Devonian in age. These dykes have similarities to the dykes hosting gold mineralisation in the Woods Point belt to the west and a genetic relationship between mineralisation at Mount Wellington and at Woods Point is postulated.
At Hill 800 an inferred mineral resource of 1,118,000 tonnes with an average grade of 1.5 grams per tonne (g/t) gold for 52,200 contained ounces of gold has been calculated.

Hill 800 Significant Historical Drilling Results
Mount Wellington Prospects and Geology
The most significant zones of alteration and mineralisation at Mount Wellington are spatially associated with significant regional aeromagnetic and gravity features in geophysical data. The scale of these geophysical signatures is consistent with the potential for large hydrothermal mineralising systems capable of producing a major ore deposit. The presence of deep-seated geophysical anomalies is consistent with Goldsearch’s genetic model for mineralisation based on Devonian-aged magmatic intrusions driving major hydrothermal systems.
Mount Wellington Project regional geophysical data, aeromagnetics draped over gravity image
At Hill 800 initial interpretations suggest the gold (with copper) disseminated sulphide mineralisation occurs as a series of stacked, flat to west dipping, north-east plunging zones within a halo of intense silica, paragonite and sericite alteration of the host andesitic volcanic and volcano-sedimentary sequence. The mineralisation appears to have a strong IP geophysical signature and there are several geophysical targets throughout the project area which, it is believed, were not adequately tested by previous explorers.
At Rhyolite Hill the gold (with silver and/or copper) mineralisation occurs as both epithermal micro veins and massive sulphides in a pervasive zone of argillic altered rhyolitic volcanics. The best gold intercept returned from limited drilling at Rhyolite Hill by previous explorers is 12.6 metres at 1.01 grams per tonne gold from 6 metres in hole RCK002. The best silver intercept is 32 metres at 27.25 grams per tonne silver and 0.32 grams per tonne gold from 69.5 metres in hole RCK003. Wide zones low grade mineralisations up to 75m @ 0.2 grams per tonne gold were also intercepted by this program. Recently drilling by Goldsearch targeted on an aeromagnetic anomaly approximately 300m north east of previously defined mineralisation intersected high grade base metal, gold and silver mineralisation within an extensive zone of hydrothermal alteration.
A 5.6 metre intersection from 220 metres returned an average gold grade (by fire assay) of 2.19 g/t with a peak one metre interval of 8.95 g/t gold. This interval also returned individual sample intervals of up to 127 g/t silver, 17.9% zinc, 1.5% lead and 0.8% copper (Table Two).

Rhyolite Creek
Diamond Drilling at Rhyolite Creek
Mineralised Core from Rhyolite Creek
At the Long Ridge prospect, a number of gossans were discovered with moderately anomalous gold and base metal values (up to 0.23ppm gold, 130ppm copper, 234ppm lead and 158ppm zinc) these gossans are also exceptionally anomalous in molybdenum (up to 3510ppm). The gossans occur in pyrite-sericite-silica altered volcanic sediments. A significant IP anomaly with coincident aeromagnetic anomalies is yet to be effectively drill-tested at Long Ridge.
Long Ridge
Limited drilling by previous explorers at Violet Hill intercepted 25 metres at 0.2 g/t gold, 0.14% zinc and 0.1% lead from 18 metres depth. This intercept was returned from drilling in the vicinity of a major structural and geophysical target identified in recent geological mapping.
Goldsearch believes the Mount Wellington project has significant potential for large magmatic-related gold and base metal ore deposits and is currently reviewing and prioritising a number of geophysical targets for future drill testing.
