Crustal architecture

Crustal architecture - new data








• Collaboration with Geoscience Australia, Macquarie


University and Chinese Academy of Sciences



– deep crustal seismic lines (Canning Coastal and Kidson Sub-basin)


– high-density passive seismic traverse along the Canning Coastal



• To better define the nature of the basement and the major

crustal boundaries



– integrate active and passive seismic, geochronology, geochemistry,

and isotopic mapping

Major crustal structures and isotope maps








• Statewide major crustal structures and
isotope maps were constructed for the


Accelerated Geoscience Program


– major crustal structures digitised from active
seismic lines, geophysical data and mapped

faults (in 3D)


– faults/shear zones that cut the full crustal

profile, are major splays of mantle-tapping

faults or separate geological terranes or
provinces

Major crustal structures and isotope maps

characterise lithospheric

architecture through time


– Sm–Nd whole rock from

felsic rocks


– Lu–Hf from zircon

Tectonic implications







• Yeneena Basin and Paterson Orogen rocks likely widespread beneath

Canning Basin as far north as Fenton Fault


– as suggested by the Canning Coastal passive seismic survey


• Mafic intrusions c. 826 Ma in Frankenstein 1 may be most northern

extension of Willouran LIP


• Granitic intrusions of c. 650 Ma extend at least 300 km north of

outcrops, close to Fenton Fault


– potential for Telfer-like Au deposits elsewhere in the orogen



• Felsic igneous rocks of Cambrian age overlap with age and

distribution of the Kalkarindji LIP

A Modern Australian Copper-Gold Growth Company






● First-mover position – largest and most strategic tenement holding


in the Stavely Volcanic Belt, western Victoria


● A committed explorer – focused on making transformational mineral


discoveries since $6m IPO in 2014


● Discovery breakthrough – outstanding shallow high-grade copper-

gold-silver discovery (September 2019), the Cayley Lode



● Resource drill-out underway – targeting maiden JORC Resource

later this year



● New style of mineralisation – Magma/Butte copper lode-style

system, never before seen in Australia


● Multiple discovery opportunities – potential to become a new


copper province as additional mineralised positions and regional

targets are tested

The Cayley Lode Discovery – Exploration History






Early Exploration


● Stream sediment copper anomalies identified by WMC in


1970’s


● 1975-1982 - Discovered as a copper prospect by Pennzoil

following up the stream sediment anomaly and finds small


pile of malachite-stained gossanous float in farmers

paddock assaying 2.9% Cu – Thursday’s Gossan


● Did geology mapping, soil surveys, RAB drilling, regional


IP, aeromagnetics, ground magnetics, 15 x diamond drill

holes – all <180m depth


● Intersected secondary chalcocite in massive pyrite in a

fault zone


● Interpreted as ‘hydrothermal, probably emanating from


an intrusive quartz feldspar porphyry’

Legge picks up Thursday’s Gossan on application on 9 Feb

2001 for new EL4556 granted to New Challenge Resources



● 2001-2004 Newcrest Operations Limited in Joint Venture

with New Challenge Resources


● Focused almost exclusively on Thursday’s Gossan

10 diamond drill holes (plus 1 diamond drill hole in the

Wickliffe copper prospect)


● Best result 32m at 0.73% copper and 0.41g/t gold from 22m

including 8m at 2.4% copper and 1.05g/t gold in VSTD001 –

The Cayley Lode Discovery – Exploration History






Early Exploration


● 2008-2013 BCD Resources (formerly Beaconsfield Gold


NL) – initially by way of earn-in, then acquisition


● Drilled 158 vertical aircore holes to define the shallow chalcocite
blanket – some with gold and silver assays, about 1/3 without – why?


● Employing an Avebury, Tasmania nickel sulphide model

● Drilled 32 RC drill holes


● Drilled 9 diamond drill holes

● Best result – SNDD001 (Stavely Nickel Diamond Drill 001)

● 7.7m at 4.1% copper, 1.1g/t gold and 77g/t silver from 95m, and

● 9.5m at 2.93% copper, 0.45g/t gold and 42g/t silver from ~150m


● And other smaller intercepts

● Beaconsfield Gold NL had come out of administration as BCD
Resources after the mine disaster and needed cash to fund

development of a refractory gold project in Queensland








8

The Cayley Lode Discovery






The Offer


● BCD Resources mandates PCF Capital to sell the Stavely


and Ararat Projects


● On review of the data, we were not overly excited about

the project -



● Had ~ 30 diamond drill holes between 150m to 400m

depth


● Best ‘porphyry’ intercept was North Limited’s drill hole

VICT1D2 with 229m at 0.22% copper and minor ‘spotty’


gold


● But did accept a site visit in January 2013 (the dust had

barely settled on the Integra Mining takeover!)













9

The Cayley Lode Discovery





The Site Visit



● All North Limited and CRA / RTZ drill core was lost,

presumed taken to the tip


● Newcrest drill holes were available but most were at the

GSV core storage facility in Werribee SNDD001 – 95m



● But the upper portion of VSTD001, including the interval

of


● 32m at 0.73% copper and 0.41g/t gold from 22m including

8m at 2.4% copper and 1.05g/t gold – was not available as

it was likely a percussion pre-collar



● Crucially, BCD Resources drill hole SNDD001 was SNDD001 – 156m

available and the tale that drill core was telling about the

mineralising fluids was unexpected…









SNDD001 – 269m

The Cayley Lode Discovery





The Site Visit – What We Saw:


● Oxidised and low pH fluid = enhanced metal carrying capacity


● Low-pH - hydrothermal fluids had dissociated and produced

H SO and HCl = higher up in the system

4
● The metal was there, SNDD001 –
SNDD001 – 95m
● 7.7m at 4.14% copper, 1.08g/t gold and 77g/t silver from 94.7m


● 9.5m at 2.93% copper, 0.45g/t gold and 42g/t silver from

154.6m


● The conclusion was that:


● Thursday’s Gossan was a very large hydrothermal

mineralizing system SNDD001 – 156m


● Fluid composition was very favourable


● There was good metal in the system


● Likely driven by a fertile porphyry at depth




SNDD001 – 269m

The Cayley Lode Discovery





The Site Visit


● Oxidised and low pH = great metal carrying capacity


● Low-pH, hydrothermal fluids had dissociated and produced

HS and HCl = higher up in the system


● The metal was there –


● 7.7m at 4.14% copper, 1.08g/t gold and 77g/t silver from

94.7m


● 9.5m at 2.93% copper, 0.45g/t gold and 42g/t silver from

154.6m


● The conclusion was that:


● Thursday’s Gossan was a very large hydrothermal

mineralising system


● Fluid composition was very favourable


● There was good metal in the system

Pre-IPO conceptual model included in 2014 prospectus
● Likely driven by a fertile porphyry at depth

The Cayley Lode Discovery – Corroborating Information


































The Corbett Report – June 2012


● Commissioned by the Geological Survey of Victoria


● Review of available exploration data and drill core



● “Inspection of available drill core has identified wall rock hosted hydrothermal alteration and Cu mineralisation typical
of the region overlying porphyry Cu-Au style intrusions.”


● “Other Cambrian volcanic rocks in Western Victoria should also be prospected for the presence of porphyry Cu-Au
mineralisation.”

The Cayley Lode Discovery





The Deal


● BCD Resources mandates PCF Capital to sell the Stavely and

Ararat Projects



● March 2013, Northern Platinum (later renamed Stavely

Minerals Limited) acquires the Stavely and Ararat Projects


privately for total consideration of $2.8m


● Conducted fieldwork, mapping, IP surveys, gravity survey in

the remainder of 2013



● Listed Stavely Minerals Limited on the ASX in May 2014 and

raised $6m to conduct deeper drilling


● Was the only successful Resources Sector IPO in 2014 – it


was a bleak period in the market at the time


● No institutional investors, all retail – ‘Mums and Dads’ and

‘Friends and Family’ – thankfully we had a following from


Integra Mining


17

First-Mover Position in Victoria’s Stavely Arc





● Two cornerstone assets – 100%-owned Stavely and

Ararat Projects



● Picked-up EL6870 in Government tender and entered into


an Earn-in and JV with Navarre Minerals



● 1,461km ground position in Australia’s new exploration
2
hot-spot of western Victoria (Kirkland Lake – Fosterville)



● Majority of exploration since 2014 focused on Thursday’s


Gossan, targeting a Tier-1, Cadia-style copper-gold

porphyry system























18

Stavely Copper-Gold Project – Thursday’s Gossan







● Located in the Grampians / Stavely Zone



● Host sequence includes (probable) Late-Proterozoic
