On December 8th, according to foreign media reports, Great Southern Mining recently identified a number of bedrock anomalies considered to have the prospect of nickel mineralization in the electromagnetic survey of its East Laverton Nickel project in Western Australia. An identified anomaly spans a huge area of 2 km by 1 km and aligns with the edge of the regional gravity anomaly, Great Southern said, providing further evidence of potential blind discovery of nickel sulphides.
The famous electromagnetic bedrock conductor found in the East Lafton project is close to the edge of the "layered ultramafic magma" intrusive body in the diorite mountain explained during the Great Sothern tenure.
The company believes that the diorite mountain intrusions show the potential for magmatic nickel sulphide deposits-a mineralization that was highlighted about a decade ago with the discovery of Sirius Resources's highly respected Nova-Bollinger deposit.
According to Great Southern, nickel sulphide exploration in Western Australia has traditionally targeted Comat rock-type mineralization, such as the Mt Keith nickel mine of BHP Billiton and the Kambalda business of Mincor Resources. Nova-Bollinger 's discovery is a watershed in Western Australia's exploration history, highlighting the state's potential for large nickel sulphide deposits in magmatic rocks.
The electromagnetic survey technology used in the East Lafton project area is moving-ring electromagnetic or "MLEM" survey. MLEM survey is the first of its kind on the magmatic complex of diorite.
Bill Amann, a leading exploration and geophysics consultant from the famous Newexco Exploration Pty Ltd company, conducted the MLEM survey. Newexco has a good record in the discovery of nickel sulphide deposits, and there are many major discoveries under the belt, including Flying Fox, Spotted Quoll and Nova.
Great Southern believes that the southeastern part of the survey area is the most important, and Newexco recommends a closer survey of electromagnetic conductors to further improve its direction.
Subsequent electromagnetic surveys over tighter grid spacing are now in the planning stage to further refine the modeled conductors prior to borehole testing.
