Sipa Resources has encountered 100 meter thick drill intersections of copper bearing gossans at its Enigma Prospect at its Thaduna Copper Project in Western Australia.
The Enigma Prospect is located less than 50 kilometres from Sandfire Resources massive Degrussa Copper and Gold Mine.
On 1 drill line,2 reverse circulation holes intersected up to 100 meters thickness of iron and silica rich gossan representing oxidized semi massive to massive sulphides at least in part,copper bearing.
Two more reverse circulation holes on another drill line intersected two iron rich gossan zones,one about 100 meters thick and the other about 50 meters thick again representing oxidized semi massive to massive sulphides also at least in part,copper bearing.
While ground conditions will not allow deeper reverse circulation testing of the gossans,a diamond drill is scheduled to begin diamond core tails later this week targeting the sulphide zone.To date,10 holes for 1,976 meters have been completed at the Enigma Prospect.
Earlier aircore drilling was designed to assess the possibility of defining one,or more,potentially economic resources within the very extensive Enigma Secondary Copper Blanket.It was also aimed at discovering vectors to the primary sulphide source of the secondary copper,which Sipa believes it is now discovering.
Having made what is considered to be a breakthrough,by discovering these vectors to the primary copper source,Sipa replaced the aircore rig with a reverse circulation rig and has since been successfully chasing several of these gossans deeper towards the sulphide zone.
The aircore drilling is also considered to have increased the likelihood of discovering potentially economic bodies of secondary mineralization,though significantly more drilling is still required.
