Corazon Mining (ASX: CZN) has intersected massive sulphides, including copper sulphides, in drilling at its Top Up Rise copper-gold project in Western Australia’s Gibson Desert region.
Samples from all drilling to date have been submitted for analysis and results are expected in August.
Top Up Rise Project targets an unexplored gravity anomaly that has a 10 kilometre by 6 kilometre core with no coincident magnetic high, a common association with many iron-ore copper-gold deposits.
Corazon is targeting IOCG intrusive related deposits, similar in style to Olympic Dam, Prominent Hill and Carapateena.
The closest outcrops (some 20 kilometres away) are anomalous in IOCG pathfinder minerals (including rare-earths, haematite, magnetite, copper, gold and uranium) and are adjacent to a large Proterozoic age intrusive alteration system with geochemical characteristics common to known world-class copper-gold deposits.
Drilling details
Drill hole TUR13DD003 intersected a broad zone of sulphide mineralisation including predominantly disseminated pyrrhotite, pyrite and chalcopyrite (copper-sulphide).
The sulphides are hosted in altered amphibolites and quartz-biotite schists, between 288 metres and 481 metres down-hole. Within this zone, two intervals exhibit particularly strong sulphide mineralisation, including massive pyrrhotite, pyrite and chalcopyrite.
This follows on a previous hole, TUR13DD001, that intersected copper mineralisation in disseminated ‘blebs’ up to 3mm in diameter.
Drilling to date has identified a spatial and timing association between sulphide and magnetite mineralisation.
Corazon noted that this is very positive as the relationship is typical of distal mineralisation assemblages within many IOCG deposits.
It added that it has yet to define the source of the gravity anomaly at Top Up Rise and will continue drilling with the TUR13DD004 hole targeting the largest gravity response within the project.
This is a significant anomaly that lies adjacent to the Western Magnetic Feature, which s interpreted to be either magnetite or pyrrhotite.
