Due to advances in metallurgical processing and the increasing gold price throughout the 2.1 Gold 1980's, open pittable gold mineralisation became the main emphasis for exploration Historically gold has been the mainstay of companies. exploration conducted around the North West VIMP area. Gold was first discovered at Into the 1990's possible meso-epithermal Wedderburn in 1852. This was followed by disseminated gold deposits in I-type granites, discoveries at Wehla, Landsborough and intermediate to mafic intrusives and sediments Stawell in 1853. The discoveries of gold spread in contact metamorphic aureoles have become with alluvial goldfields opened up at Carapooee the focus of exploration for gold mineralisation. in 1854, Stuart Mill in 1856, Emu in 1857, Geophysics has shown possible extensions to Fentons Creek, Burkes Flat, Rostrons and greenstone belts which have the potential for Navarre in 1858 and Redbank in 1860.

Small inferred resources were delineated at Throughout the 1960's the principal target for Landsborough (EL's 833, 1221, 1538, 3255), gold was unworked extensions to previously Kooreh (EL 938), Burkes Flat (EL 1173), mined deposits.

A series of extensive regional programmes were "Indicators" according to historical literature conducted throughout the North West VIMP played an important role in the concentration of area searching for heavy mineral sands. gold. The emphasis of exploration shifted Following the initial discovery of heavy mineral towards indicator belts and disseminated gold deposits near Kerang in the Parilla Sand, outside vein deposits from the late 1960's into exploration has been conducted by Reef Oil, the 1970's throughout the Wedderburn- Westralian Sands (Tioxide & Austiex), CRAE, St Arnaud-Pyrenee Ranges area.

Anomalously high base metal geochemistry near Wedderburn led to the exploration for Pb- Zn hosted shale mineralisation (EL 919). In the 1990's models for base metal mineralisation have included structurally controlled, intrusive related copper mineralisation and volcanogenic massive sulphide mineralisation. Airborne geophysical surveys have been used to select prospective areas. Molybdenum disseminated in intrusives or porphyries was the target of exploration around Mafeking and Zumstein (EL's 117, 118).
2.4Brown coal
Tertiary brown coal was the original target of the regional exploration conducted by CRAE over the Murray Basin. Sub-economic resources were identified in the Wycheproof, Torrumbarry-Tandarra and Cohuna areas (CRAE, 1989 [7855]). Poorly developed coal seams were identified at Hopetoun (Brunker, 1982 [7550]) and coal of a limited extent, confined to the basal Renmark Group, was identified at Robinvale (CRAE, 1982 [7539]).
2.5Diamonds
Diamond exploration in the area has consisted of drilling thumbprint anomalies, detected through airborne magnetic surveys. These were thought to represent pipe like ultramafic intrusions. The geochemistry of many of the pipes suggested an affinity with alkali basalts or nephelinites (CRAE, 1990 [3439]). No diamonds were recovered. MINERAL EXPLORATION HISTORY - NORTH WEST VIMP AREA 5

Both WIM-style and coarse grained HM mineralisation was intersected in regional reconnaissance drilling throughout the licence. Initially a resource (Gowne Resource) was located in the northeast portion of the title and follow up drilling identified three discrete areas aggregating 12 km². Infill drilling failed to locate significant extensions to the known zones of moderate grade WIM-style mineralisation in the Gowne Resource. Drilling results showed mineralisation in the licence area is low grade, discontinuous and can occur in several thin layers to significant depths.
Reason for relinquishment: Mineralisation of sufficient grade, extent or thickness to warrant further exploration was not encountered.
