Kavango Resources believes KSZ might contain 'magma plumbing system' for massive sulphide deposit

Kavango Resources PLC (LON:KAV) has reported further indications that its Kalahari Suture Zone (KSZ) project in Botswana has similar geology to other massive sulphide orebodies elsewhere.

Drilling at KSZ has identified what seem to be multiple magma conduits, which would have supplied molten lava to the surface 180mln years ago.

The final hole in its attest programme intersected a 16m gabbroic sill at 120 metres from surface, with signs of intensive alteration by heat.

The extent of the heat alteration is unusual said Kavango, which suggests this was a formerly active conduit that flowed magma to the surface over an extended period.

Kavango's geologists now believe they have intersected a small part of a very extensive magma plumbing system typical of the massive sulphide orebodies at Voisey Bay in Canada, one of the world's largest Ni/Cu/Co deposits.

Next steps will be the application of downhole geophysical techniques to locate accumulations of metal sulphides within the gabbro.  

In a statement, Michael Foster, Kavango’s chief executive said: “If it can be established that the disseminated metal sulphides seen in the gabbroic sills are a primary feature, then there is an excellent possibility that economically viable metal sulphide deposits exist within the KSZ.”
