The expansion was prompted in part by the lodgement of Exploration Licence applications covering a vast area of some 10,130 square kilometres by
Anglo's applications, which comprise one of the largest holdings by a single company in
Impact Minerals Limited Managing Director Dr
'In addition we think it is also a direct recognition of the importance of the proposed mobile belt in this part of the State, a belt we have recently understood to be explored for diamonds in the past, and that we interpret to be a deep structure that may have tapped the mantle and allowed nickel-copper and platinum group metals to migrate into the crust.
'Such deep structures are critical components to the formation of major deposits like Nova-Bollinger and the recent discovery at Mawson. Impact is currently completing reconnaissance work along roads and tracks to move this exciting project forward before grant whilst waiting for statutory drilling approvals at our priority nickel-copper-PGE project at Broken Hill,'
About the
The Arkun project, which now covers about 1,900 square kilometres, is centred between York and Corrigin 130 km east of
A subsequent interpretation of regional magnetic data by Impact has identified the area as lying within a major deformation zone or mobile belt that trends NW-SE from the Moora-Julimar-Yarawindah area through Arkun and which may contain deformed and metamorphosed equivalents of those rocks. This belt is generally not recognised in many regional geology maps and yet is self-evident in the magnetic data. This is a significant breakthrough in understanding for Impact.
The mobile belt is about 500 km long and up to 30 km wide, and is of a scale that suggests it may mark an ancient terrane boundary or proto-craton margin. Such geological provinces (of varying ages) are well known around the world as prospective terranes for hosting major nickel-copper-PGE deposits with examples such as Nova-Bollinger and Mawson, the Thomson fold belt in
In addition, the project is centred on a significant WNW-trending gravity high evident in regional gravity data and numerous 'eye structures' in regional magnetic data similar to those at Nova-Bollinger. Such gravity and magnetic anomalies are used as targeting criteria for similar deposits throughout the
