Formation of magmatic sulphides

Stage 1: Lava Ascending to Surface 180 to 185 million years ago Dyke brings magma up through faults or weaknesses in the basement rocks Lava owing from volcanic fissures at surface

 

 

Stage 2: The magma is constantly replaced, as the lavas ascend to the surface This brings more metals into the chamber for interaction with the sulphur

v Stage 3: Metal Sulphide Segregation Large volume of slow cooking gabbroic magma allows development of cumulate textures Metal sulphides segregate from the cooling magma & gravitate into trap sites

Stage 4: Present Day Kalahari cover comprises of loose sediments and sand Drilling will aim to discover large-scale metal sulphide deposits, rich in copper, nickel and platinum group metals

Stage 5: Electromagnetic (“EM” ) Surveys A 1km2 Large Loop enablesa ground electromagnetic survey over a 9km sq. target area Traverse lines set 200m apart for the receiver to walk up and down, recording incoming magnetic signals
