Kavango Resources PLC (LON:KAV) has hit early-stage signs of mineralisation during drilling on its Kalahari Suture Zone project (KSZ) in Botswana.
The exploration intersected disseminated sulphides in two high-level gabbro sills, said the standard-listed junior, which is exploring near the town of Hukuntsi.
The sills were intersected at 340 metres and 367 metres respectively and were each about one-third of a metre thick.
Gabbro sills were also intersected in two shallower drill holes.
Kavango said that in this type of deposit, the gabbro sills and dykes represent conduits along which large volumes of magma passed on their way to the surface.
"What is important is the amount of magma that passed through the conduit - leaving metal-rich, immiscible sulphide liquid behind to solidify into an orebody," the company said in a statement.
Michael Foster, Kvango's chief executive commented: "We are highly encouraged by the discovery of disseminated metal sulphides in gabbro sills and the incorporation of coal seams into the melt.
"This lends significant support to Kavango's belief that the post-Karoo magma chambers emplaced along the KSZ developed sulphur-rich magma that allowed for the crystallization of large volumes of metal sulphides (copper/nickel/platinum).
" It is expected that the study of thin sections and whole-rock analyses (assays) will confirm the primary origin of the sulphides and thus the potential for these gabbros to host economically viable metal sulphide deposits," he added.
