Slide 4: Contents
CONTENTS For personal use only 1. KANMANTOO MINE – THE KEY 2. KANMANTOO MINE – WHAT HAVE WE LEARNED 3. EXPLORATION IN THE REGION Utilising existing infrastructure and cash flow at Kanmantoo to create Company transforming mining projects 4
Slide 5: Location
LOCATION For personal use only Hillgrove Resources Ltd (ASX:HGO) operates the Kanmantoo Copper-Gold Open Pit in the south-east of South Australia. Located approx. 55kms from Adelaide Grid power, water on site Local labour force Awards for Community Consultation Leader in Environmental Rehabilitation
Slide 6: Location
LOCATION For personal use only The Kanmantoo Copper-Gold Mine is located along the Tasman Line of the Delamerian Orogen of south-east South Australia. The Tasman Line (Foden et al, 2006) is interpreted to represent the continent-vergent deformation zone of the Early Cambrian, then its transition in
Slide 7: Andean Type?
ANDEAN TYPE? For personal use only A quick re-cap Here is an interpretation of the Delamerian Orogen in south- east South Australia (after Belperio et al, 1998 and East West Foden et al, 2006) Kanmantoo is located in the rift basin – the Kanmantoo Trough And the Kanappa – Mt Rhine projects are locat
Slide 8: A Copper Gold Enriched Province
A COPPER GOLD ENRICHED PROVINCE For personal use only The regional magnetics clearly show the Kanmantoo Trough sedimentary basin and the magmatic arc (Padthaway Ridge) to the east Significant projects for Hillgrove within the Delamerian Orogen include Kanmantoo Cu-Au Kanappa Cu - Au Mt Rhine Cu – Au
Slide 9: A Copper Gold Enriched Province
A COPPER GOLD ENRICHED PROVINCE For personal use only And then there is the portion of the Magmatic Arc that is now covered by Tertiary and the Murray Valley sediments Quaternary Cover So what have we learned from the mining of Kanmantoo about the types of orebodies that could be found, undercover?
Slide 10: What Have We Learned? Magmatic Activity Is Important
WHAT HAVE WE LEARNED? – MAGMATIC ACTIVITY IS IMPORTANT For personal use only Dating of the copper-gold lodes shows a late Cambrian – early Ordovician age 469 Ma – Focke, 2010 492 Ma – Wilson, 2009 Earliest igneous activity within the pit are peraluminous dykes subjected to D2 deformation, but pre-mi
Slide 11: What Have We Learned? Fe and Au Are Important
WHAT HAVE WE LEARNED? FE AND AU ARE IMPORTANT For personal use only Mineralising system is Fe-Cu-Au-Bi Note * Fe rich garnet, biotite, chlorite with ore zones (HyLogger – DPC) Fluids are acidic and likely magmatic Fe as both magnetite and pyrrhotite Last deformation event is K-rich with sulphides Da
Slide 12: Kanappa Cu-Au
KANAPPA CU-AU For personal use only The Kanappa Cu-Au zone is 50kms from Kanmantoo A series of pegmatites and aplites intrude into a sequence of Fe and potassic altered schists and carbonates Soil copper zone 4.4kms long Geochem zoning from west to east Cu-Zn => Cu-Bi => Cu-Au => Au => W Peak rock c
Slide 13: Kanappa – Isometric View of Copper Geochemistry & Mags
KANAPPA – ISOMETRIC VIEW OF COPPER GEOCHEMISTRY & MAGS For personal use only Copper Geochemistry East 3D Magnetic Model KEY TAKEAWAYS Magnetic anomalism is strong and not related to rock types, implying it is alteration related Best magnetic zones are correlated with the best geochemistry over 2km s
Slide 14: Kanappa – Isometric View of All IP
KANAPPA – ISOMETRIC VIEW OF ALL IP For personal use only North 2 km long zone of coincident Geochemistry, Magnetics, IP Chargeability 250m wide Open to south KEY TAKEAWAYS Large scale coincident Cu-Au geochem, magnetics, and IP anomaly Strong alteration system proximal to Igneous Arc magmatism to ea
Slide 15: Mt Rhine Cu-Au
MT RHINE Cu-Au For personal use only The Mt Rhine copper-gold zone is 10kms from Kanappa Soil copper zone 1.7kms long Peak rock chips of 13% Cu 49.8g/t Au (separate samples) Peak Channel Sampling of 6m @ 15.9g/t Au Much higher gold tenor cf Kanappa Also completed soils, mags, IP KEY TAKEAWAYS Larg
Slide 16: Mt Rhine Cu-Au
MT RHINE Cu-Au For personal use only 1.7 kms long zone of Chargeability, Section line for next slide Magnetics, & Cu geochemistry IP Chargeability model on 200m sections North Magnetic 3D Model KEY TAKEAWAYS Stacked sections of IP chargeable model, with 3D magnetic model superimposed Continuous zone
Slide 17: Mt Rhine Cu-Au – Best Cross Section
MT RHINE Cu-Au – BEST CROSS SECTION For personal use only East Cu Soil anomaly IP Chargeability model 3D Magnetic model KEY TAKEAWAYS Mt Rhine has a strong zone of Cu geochemistry, magnetic and IP Chargeability anomalism Over a 1.7km long, 500m wide zone Proximal to Igneous Arc to east 17
Slide 18: From Known to Unknown
FROM KNOWN TO UNKNOWN For personal use only Kanappa Significant projects for Hillgrove within Mt Rhine the OUTCROPPING portion of the Delamerian Orogen include Kanmantoo Cu - Au Kanmantoo Kanappa Cu - Au Mt Rhine Cu – Au KEY TAKEAWAYS The geochemical footprint is large and being characterised by H
Slide 19: From Known to Unknown
FROM KNOWN TO UNKNOWN For personal use only And then there is the Under-cover portion of the Magmatic Arc The work underway at Kanmantoo is enabling Hillgrove to • characterise the Geochemical Footprint of Cu-Au mineralisation • develop vectors to the next Cu-Au orebody. A geochemical footprint is a
Slide 20: Kanmantoo – What Have We Learned
For personal use only KANMANTOO – WHAT HAVE WE LEARNED It is a large Fe-Cu-Bi-Au system It appears to be post peak-metamorphism It appears to be coeval with magmatic activity Strong gold endowment is late and associated with low Cu 5m @ 32.3g/t Au, 0.3% Cu REGIONAL COPPER-GOLD PROJECTS M
