Carnavale Resources Limited (ASX:CAV) has confirmed high-grade tin mineralisation associated with the large stockwork of quartz veins in diamond drilling at its Kikagati Tin Project in southern Uganda.
Drilling has shown the mineralised quartz veins extend 3,000 metres along strike and about 900 metres down-dip, with the 100-metre-thick host sequence open at depth and along strike.
The mineralised quartz veins are hosted in a quartzite unit up to 100 metres thick with quartz vein densities ranging from 14% to 22% by volume.
“Very rare and large outcropping”
Carnavale managing director Andy Beckwith said: “Kikagati is a very rare and large outcropping tin system with substantial open pit potential.
“Recent drilling has ticked all the boxes such as confirming the high-grade nature of mineralisation, frequency of quartz veining and the potential scale of the geological target.
“Our immediate task is to complete the required drilling program to earn Carnavale’s 51% equity.
“Beyond June the next step will be to complete the additional infill drilling to establish an initial inferred resource and assess the potential for bulk open pit mining methods.”

Beckwith added: “Ore sorting of the quartzite from the mineralised tin bearing quartz vein material is also seen as an economic aspect to evaluate.”
The following table highlights tin grade from samples containing quartz veining and visible cassiterite:
The average tin grade of the quartz veins with visible cassiterite averages 1.23% tin using a 0.0% lower cut-off grade and 1.8% tin using a 0.1% tin lower cut-off grade.
The cassiterite is highly nuggety which implies the quartz veins have potential to host tin mineralisation.
