Mt Alexander Belt
The Mt Alexander Belt trends north-northwest, the typical orientation of greenstone belts in Western Australia’s Yilgarn Craton.
Historical drilling at the Mt Alexander Belt identified komatiite hosted nickel sulphide mineralisation over a 7km strike, including several intersections of massive nickel sulphides. This previous drilling was completed on a wide-spaced reconnaissance pattern, often 1km apart.
St George believes that the Belt remains underexplored and has strong potential to host a significant nickel sulphide deposit.
In addition to the main Mt Alexander Belt, three additional magnetic trends are observed to the west and east of the Mt Alexander Belt. These magnetic features may be ancillary ultramafic belts trending parallel to the main Belt. These belts have never been explored and present an opportunity for St George to carry out the first ever systematic exploration for nickel sulphides on these prospective areas.
The graphic below contains high resolution magnetic data (RTP 1VD) for the four granted tenements at Mt Alexander. The Mt Alexander Belt appears as a strong magnetic feature with similar strong magnetic features to the east and west of the main Belt. Drill holes with nickel sulphides are shown in red.
