Slide 3: IOCG Copper Project
IOCG Copper Project • Brazil has the largest known concentration of large tonnage IOCG and ISCG deposits For personal use only • These are all structurally controlled post orogenic type deposits, same IOCG deposit subtype as Olympic Dam • Size and grade of median IOCG deposits are a very attractive
Slide 4: Escape tectonics and the Borborema Province
IOCG Copper Project Escape tectonics allow the crustal rocks to be squeezed away from colliding cratons, For personal use only creating the deep seated fractures necessary for IOCG deposits to form. The Borborema Province is an escape tectonics province with numerous deep seated shear zones and many
Slide 5: Borborema Province IOCG occurrences and target scale
IOCG Copper Project The Borborema Province is an escape tectonics province with For personal use only numerous deep seated shear zones and many known post orogenic IOCG type copper and iron occurrences of Cambrian age Occurrence types include breccia hosted and vein hosted Target median scale is 120
Slide 6: Rift zones and GMN tenements
IOCG Copper Project • Main post tectonic Cambro-Ordovician rift zones named For personal use only • Older rift zones present dating back to at least Lower Proterozoic • Deep seated faults • Known IOCG type Cu mineralisation (green stars) • GMN tenements within green rectangles total 1820 km2 Sources
Slide 7: Coccoci, São Julião and Iguatu tenements
IOCG Copper Project • Coccoci and São Julião tenements have known IOCG copper and iron For personal use only occurrences • Iguatu tenements have known iron occurrences and numerous magnetic anomalies indicative of additional iron occurrences, • Tenements area 1610 km2 Sources - Map: 5. CPRM website
Slide 8: Coccoci and São Julião tenements geology
IOCG Copper Project • Coccoci and São Julião tenements have at least 13 confirmed IOCG Cu For personal use only occurrences, many iron plus other copper occurrences • Extensive areas with potassic alteration and/or uranium enrichment are present • Structures related to the escape tectonics of the Bo
Slide 9: Iguatu tenements and underexplored region
IOCG Copper Project Iguatu tenements have known iron occurrences and For personal use only numerous magnetic anomalies indicating more iron occurrences Underexplored region Detailed academic work in Sao Juliao and Cococi shows IOCG copper as well as unknown type copper Sources - Map: 6. Maas et al 2
Slide 10: Ararenda tenements and IP anomaly
IOCG Copper Project Ararenda tenements (210 km2) have known IOCG copper as For personal use only well as many Fe occurrences IP survey carried out as part of theses work. IP anomaly extends onto GMN tenements and the IP anomaly is open in all directions. Sources - Map: 8. Silva 2016; 10 Google Earth
Slide 11: Copper mineralisation style and alteration
IOCG Copper Project Known Cu mineralisation undeformed so post tectonic and latest stage of alteration and mineralisation – typical of IOCG type For personal use only Mineralisation probably related to late hydrous post tectonic granites of Cambrian age, similar to dated IOCG mineralisation in Jaiba
Slide 12: Previous exploration - not in GMN tenements
IOCG Copper Project PREVIOUS EXPLORATION- not in GMN Tenements Existing IP survey interpretation with E-W lines and SE plunge to mineralisation For personal use only Volume estimated at 70 million m3 of highly chargeable rock ( ̴ 250 mt) Late sulphides overprint all earlier mineralisation “chalcopyr
Slide 13: Systematic exploration planning
IOCG Copper Project SYSTEMATIC EXPLORATION PLANNING For personal use only • Stream sediment sampling is the most cost effective way to cover large areas of ground rapidly. This is in progress. • Sites have been designed to cover the tenements effectively and to allow a focus on near surface minerali
