Sipa Resources has made two strong copper intersections that support the belief that potentially economic bodies of secondary copper mineralization exists at its Enigma Prospect within the Thaduna copper project located in Western Australia.
It also supports the interpretation of the gossan intersections as representing oxidized semi massive to massive sulphide mineralization.
The intersections from recent reverse circulation drilling on Sections A – A’ and B – B’ returned assays of 9 meters at 4% from 101 meters and 6 meters at 1.5% copper from 81 meters. These represent the first laboratory chemical analyses received from the first five holes at the program which is currently up to 15 holes.
One of the holes also returned 66 meters of black powder with no rock chip that XRF analysis showed contained more than 0.1% copper. This is presently interpreted as completely leached and decomposed Upper Gossan Zone.
The geology of Section B – B’ is now interpreted as a relatively shallow south dipping zone of mineralization with a thicker underlying zone that was not reached by recent holes.
Although copper values are more subdued in the lower zone, than in the upper zone, multi element geochemistry and rock textures demonstrate that this thick zone is well worth testing in fresh rock as it also very likely represents weathered massive to semi massive sulphide.
