Slide 3: Highlights of the Delamerian Terrain
HIGHLIGHTS OF THE DELAMERIAN TERRAIN •Cu, Au ENDOWED •Cu, Pb, Zn, Au •Cu, Mo •Cu, Au, Mo outcrop in various areas SHALLOW COVER •60‐100 metres cover over large areas •No regional exploration for ~20 years UNDER‐EXPLORED •New technology now available •Minex CRC with large $$$ into Delamerian •Section
Slide 4: Near, Medium and Long Term Growth
NEAR, MEDIUM AND LONG TERM GROWTH Hillgrove has a staged Exploration and Development strategy in the Delamerian STAGE 1 ■ Converting Mine Lease assets to Reserves at Kanmantoo STAGE 2 ■ Establishing resources near the Kanmantoo mine for production growth STAGE 3 ■ Exploration of Region for the next
Slide 5: So What's So Good About the Delamerian in Sth Aust?
SO WHAT’S SO GOOD ABOUT THE DELAMERIAN IN STH AUST? Apart from; ■ Extensive Copper fertility ■ Host to Stavely Porphyry Cu-Au (in Vic) ■ Several Porphyry Cu-Mo occurrences ■ Extensive calc-alkaline and alkaline volcanism and intrusives ■ Identified by GA and USGS as the third most prospective Porphy
Slide 6: So What's So Good About the Delamerian in Sth Aust?
SO WHAT’S SO GOOD ABOUT THE DELAMERIAN IN STH AUST? What’s with the IOCG label on slide 4 and in previous presentations? Dr R. Taylor has undertaken detailed petrology on a series of > 100 rock specimens from Cambrai down to Keith, incl Kanmantoo. He concludes; ■ “… although not perfect the sequence
Slide 7: So What's So Good About the Delamerian in Sth Aust?
SO WHAT’S SO GOOD ABOUT THE DELAMERIAN IN STH AUST? There are Multiple Mineralising events, so let’s keep on open mind; ■ 522 - 514 Ma – SHMS Base metals – e.g. Angas, Mt Torrens ■ 500 – 490 Ma – Epigenetic Cu with D2 – e.g. Kanmantoo (Uni Adelaide – HGO work) ■ A reminder – The Delamerian orogen is
Slide 8: 6,150 Sq Kms of Opportunities
6,150 SQ KMS OF OPPORTUNITIES Hillgrove hold 6,150 sq kms of EL’s of opportunities in the Delamerian. Topics within this presentation include: ■ How deep is the cover? ■ Does geochemistry work with transported cover? ■ Kanappa – a Cu-Au skarn ■ Colebatch – a Cu-Mo Porphyry ■ Sherlock – a Zn-Pb-Cu vo
Slide 9: How Deep Is the Cover?
HOW DEEP IS THE COVER? Passive Seismic used for the first time in the area. ■ Worked really well when trialled over two areas already drilled ■ A great discriminator of depth of cover ■ Identified large areas with < 100m cover ■ A better constraint for gravity modelling A new model of depth to basem
Slide 10: Does Geochemistry in the Murray Basin Work?
DOES GEOCHEMISTRY IN THE MURRAY BASIN WORK? A number of analytical techniques trialled over two known mineralised areas covered by 50 – 100m of Tertiary marine sediments ■ Same areas sampled on two occasions ■ Five different analytical methods tested ■ Used GSSA ASTER and radiometric imagery to “lev

Slide 12: Discovery of Magmatic Skarns
DISCOVERY OF MAGMATIC SKARNS Kanappa The Kanappa Cu-Au zone is 50kms from Kanmantoo A series of diorites, pegmatites and aplites intrude into a sequence of schists and carbonates Soil copper zone 4.4kms long Petrology of the drill core shows the 250m wide alteration zone overprints both sediments an
Slide 13: Copper Fertility of Monzonites
COPPER FERTILITY OF MONZONITES Global fertility plot after Loucks 2014 The red circles are the whole rock geochemistry of the monzonites at Kanappa, and these are very similar to signatures of the global Porphyry Copper felsic intrusives Kanappa Magmatism is consistent with Cu Porphyry fertility ind
Slide 14: Cu-Mo Veined Porphyritic Granite
CU – MO VEINED PORPHYRITIC GRANITE Colebatch Field sampling of Cu-Mo outcrop Petrology Quartz monzonites, fluorite, molybdenite, rapakivi textures, Interpreted as classic Porphyry Cu-Mo system Never drilled 14
Slide 15: Sherlock – Cu-Zn-Pb
SHERLOCK – CU-ZN-PB Sherlock Drill core with ■ SHR08 0.5m @ 11.6% Cu, 1.1% Zn from 102m1 in an interbedded sequence of; ■ Basalts, gabbros, and dolerites ■ Calc-silicates ■ Tuffs ■ Meta-sediments ■ Andesites Sulphides include pyrite, sphalerite, chalcopyrite, galena, pyrrhotite Nothing like the Kanm
Slide 16: Alamil – Epithermal Cu?
ALAMIL – EPITHERMAL CU? Alamil Drill core with narrow veins and disseminated adularia/chlorite/epidote/galena zones of chalcopyrite and sulphides in diorite over 267m, from 86m depth Perhaps akin to an “epithermal mineralising system”?
