HIGH COPPER GRADES AT KALKAROO

HIGHLIGHTS

  • Consistent widths and high grades of copper-gold sulphide mineralisation in recent Kalkaroo resource infill drillholes, including: 57 metres of 1.24% copper and 0.89 g/t gold

54 metres of 1.20% copper and 0.75 g/t gold, including

25 metres of 1.96% copper and 0.91 g/t gold.

  • Ongoing discussions with potential mining contractors and project financiers.

  • Initial feedback from the Department for Energy and Mining ( DEM ) on the Kalkaroo Program for Environment Protection and Rehabilitation ( PEPR ) is being addressed.

  • Subject to timely completion of the various outstanding pre-development tasks, the Kalkaroo project remains on track to commence during early 2022.

  • Drilling has now shifted to infill resource confirmation drilling at East Kalkaroo.

Havilah’s Technical Director, Dr Chris Giles, said:

“Infill resource confirmation drilling continues to demonstrate good continuity of sulphide mineralisation at consistently economic copper and gold grades as is characteristic of the Main Kalkaroo orebody.

“This is positive for the longer-term sulphide development potential.

“In the meantime we continue to engage with the DEM concerning permitting approvals as well as potential mining contractors and financiers in relation to the West Kalkaroo gold deposit.

“Our priority objective remains advancing the West Kalkaroo gold open pit towards development during 2022, subject to a final investment decision by the Havilah Board, obtaining financing and final South Australian government approvals,” he said.

Havilah Resources Limited ( Havilah or the Company ) ( ASX : HAV ) is pleased to provide a further update on progress of work at its large-scale Kalkaroo copper-gold-cobalt deposit ( Kalkaroo ) in northeastern South Australia, near Broken Hill. Havilah’s priority focus during recent months has been on advancing several key tasks that are required to commence the West Kalkaroo open pit gold mine, and also carrying out additional infill drilling to gain greater confidence in the mineral resource.

Two infill reverse circulation ( RC ) drill transects were completed by Havilah’s drilling crew along strike of the proposed West Kalkaroo gold open pit to establish continuity of the mineralisation between the existing 100 metre spaced drill sections that were used to define the Kalkaroo JORC Mineral Resource (Figure 1). These results will be used for future mine planning studies.

These RC holes were mostly designed to target the deeper sulphide mineralisation. Widespread copper and gold mineralisation was intersected in all drillholes, with grades and widths of sulphide mineralisation very typical of the Main Kalkaroo deposit. Significant results are summarised below.

KKRC0607 : 32 metres of 1.69% copper and 0.78 g/t gold from 136-168 metres (copper sulphide zone) KKRC0609 : 54 metres of 1.20% copper and 0.75 g/t gold from 120-174 metres (copper sulphide zone) including 25 metres of 1.96% copper and 0.91 g/t gold from 137-162 metres

KKRC0610 : 57 metres of 1.24% copper, 0.89 g/t gold and 289 ppm (parts per million) cobalt from 117-174 metres (in copper sulphide zone to end of hole at 174 metres).

Notably, drillhole KKRC0610 ended in copper-gold mineralisation and the last 5 metres averaged 0.13% molybdenum . Elevated molybdenum is characteristic of this part of the orebody. In addition, cobalt is also elevated, and given all cobalt reports to the pyrite, this indicates potentially high cobalt grades in the pyrite concentrate in this case.

Although it was not specifically targeted, these drillholes did return appreciable gold mineralisation in the shallower oxidised (saprolite gold) zone as follows:

KKRC0608 : 39 metres of 1.36 g/t gold from 98-137 metres (saprolite gold zone) KKRC0607 : 4 metres of 0.71 g/t gold from 88-92 metres and

11 metres of 0.71 g/t gold from 108-119 metres (saprolite gold zone)

KKRC0609 : 4 metres of 0.88 g/t gold from 100-104 metres (saprolite gold zone) KKRC0610 : 4 metres of 3.45 g/t gold from 106-110 metres (native copper zone).

These gold intersections will be followed up in due course with more closely spaced, shallow aircore drilling prior to any future eastward extensions of the West Kalkaroo gold open pit (Figure 1).

This drilling confirms that upon completion of mining the oxidised ore in this area, the open pit floor should expose at least a 100 metre wide zone of copper-gold sulphide mineralisation with attractive grades (see cross-sections, Figures 2 and 3).

These RC drillholes are on a new drill section line halfway in between earlier 100 metre spaced drill section lines that were used to define the Kalkaroo JORC Mineral Resource. The results for the three drillholes are broadly consistent and confirmatory of the earlier drilling results. Of particular note are the relatively high copper grades and the associated cobalt and molybdenum. Considerable coarse-grained molybdenum is associated with the copper-gold mineralisation in this part of the orebody and extends for at least 1.5 km to the east. Recovery tests for the molybdenum will be undertaken in the future. Cobalt, which is exclusively hosted by pyrite, could be recovered in a pyrite concentrate that also contains appreciable gold and copper (average grade of 2.5 g/t gold and 1% copper respectively in several pyrite flotation concentrate samples from previous metallurgical test work).

Kalkaroo copper-gold project environmental, social and governance (‘ESG’) credentials

There is increasing recognition of the importance of a mineral resource projects’ ESG ranking, to the extent that it is becoming a key investment criteria for many investment funds and project financiers. This is a very broad subject, but for shareholder’s benefit, Havilah has provided below some brief guidance of how it views the Kalkaroo copper-gold project from an ESG perspective, in advance of expected more detailed formal ESG reporting in the future.

1. Environmental (the ‘E’ in ESG)

Havilah is presently engaging in a rigorous PEPR approval process with the South Australian government’s mining regulator (the DEM). The PEPR documents in detail how Havilah proposes to mitigate known environmental risks and its mine closure plans. The emphasis is on sustainable longterm environmental outcomes that ultimately minimise disturbance to the natural environment by the proposed Kalkaroo mining operations, as far as practicable. This is achieved by a series of environmental compliance and monitoring procedures that are enforced by the regulator via regular reporting of results against stated objectives. Havilah is not presently aware of any specific environmental concerns, including threatened flora and/or fauna, which would be directly impacted by the proposed Kalkaroo mining operation.

Havilah owns the 550 km[2] Kalkaroo Station pastoral lease on which the Kalkaroo deposit is located and has for some time been undertaking conservation and environmental enhancement programs on the land. It therefore fully endorses the concept of minimal environmental disturbance, biodiversity and sustainable environmental outcomes in all of its activities and Havilah has already taken practical steps to achieve this on the Kalkaroo Station pastoral lease.

Kalkaroo is uniquely located in one of the most favourable places in Australia for combined wind and solar power generation. Havilah is presently commissioning its own pilot solar-wind-battery power generation system at the Kalkaroo exploration basecamp. Transitioning to renewable power sources at the Kalkaroo basecamp demonstrates the Company’s ongoing commitment to responsible resource development across its operations and activities. This renewable energy power plant will take Havilah a step closer to achieving its sustainability goals and reduce reliance on diesel gensets.

Operation of this system should also provide valuable information on the efficacy of wind and solar power in the region, which ultimately could assist Havilah to design a renewable energy generation system to power the Kalkaroo mine. It is Havilah’s ultimate goal to utilise these natural geographic advantages to maximise the generation and use of renewable energy.

2. Social (the ‘S’ in ESG)

Northeastern South Australia is an economically depressed area, and sadly the once thriving railway town communities of Olary, Mannahill and Cockburn are struggling to survive. Currently, pastoralism is the main employer in the region.

Havilah supports local communities and believes mining activity is one important way to help rejuvenate local towns.

The Kalkaroo project has a Native Title Mining Agreement signed by the relevant local Native Title holders (refer to ASX announcement of 19 December 2018), which ultimately should see benefits flow through to the communities after mining operations commence.

The wider community expects Havilah to behave in a responsible manner, and in its almost twenty years of operating in the northeastern region of South Australia, Havilah has a record of fulfilling its

Page | 5

Havilah Resources Limited

==> picture [62 x 31] intentionally omitted <==

statutory rehabilitation obligations and has at all times maintained cordial relations with landholders, Native Title claimants and other relevant stakeholders.

Kalkaroo’s large resources point to a long-life, large-scale mining operation, potentially supplying ‘green technology’ metals that the modern world needs longer-term, including copper, cobalt, rare earth elements and molybdenum, with very low levels of associated undesirable elements such as uranium and arsenic. The operation could provide many well paid jobs and once in production would pay royalties to the South Australian government over its mine life. In all of these ways Havilah would be fulfilling an important social role in the wider community.

3. Governance (the ‘G’ in ESG)

Havilah takes its corporate governance obligations seriously. Adherence to corporate governance principles according to its particular circumstances is a natural outcome of Havilah’s clearly defined set of core values which are at the heart of all that it does (published on Havilah’s website).

The South Australian government oversees and strictly enforces a comprehensive regulatory framework to protect a wide range of community interests and collectively agreed objectives (eg. environmental protection, safe working environment). Havilah’s governance processes ensure as a minimum, compliance with government regulations, relevant reporting obligations and the implementation of industry best practice operating standards.

Provided Havilah complies with the regulations that govern its operations, its long-term security of tenure and ownership of its mineral assets is not at risk in South Australia. This is not the case in some countries in the world.

It also means that future buyers of minerals from the Kalkaroo project can be confident that they have been produced according to the best practice ESG standards. This potentially represents a material competitive advantage for the Kalkaroo project versus minerals sourced from jurisdictions where regulations are not adequately enforced and/or mining practices may be undesirable. The importance of ethically sourced minerals is only likely to increase over time and may result in preferential purchasing and/or financing by end users.

About the Kalkaroo copper-gold-cobalt deposit

Havilah’s 100% owned Kalkaroo copper-gold-cobalt deposit contains JORC Mineral Resources of 1.1 million tonnes of copper, 3.1 million ounces of gold and 23,200 tonnes of cobalt. It has an open pit JORC Ore Reserve of 100.1 million tonnes at a 0.89% CuEq of which 90% is in the Proved category (refer to JORC tables below taken from Havilah’s 2020 Annual Report in ASX announcement of 27 October 2020). As such, Kalkaroo is one of the largest undeveloped open pit copper-gold deposits in Australia on a CuEq Ore Reserve basis.

Low sovereign risk, advanced, large-scale open pit copper-gold development opportunities like Kalkaroo, with associated land ownership, are rare at a time when renewable energy and electric vehicles are adding to the demand for copper (and cobalt). South Australia’s mining friendly government and enforcement of world’s best practice ESG (environmental, social and governance) regulations means the Kalkaroo project ticks all boxes as a potential future source of ethical copper and gold (plus potentially cobalt, REE and molybdenum).

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques

Nature and quality of sampling (eg cut channels,
random chips, or specific specialised industry
standard measurement tools appropriate to the
minerals under investigation, such as down hole
gamma sondes, or handheld XRF instruments, etc).
These examples should not be taken as limiting
the broad meaning of sampling.

Include reference to measures taken to ensure
sample
representivity
and
the
appropriate
calibration of any measurement tools or systems
used.

Aspects of the determination of mineralisation
that are Material to the Public Report. In cases
where ‘industry standard’ work has been done this
would be relatively simple (eg ‘reverse circulation
drilling was used to obtain 1 m samples from
which 3 kg was pulverised to produce a 30 g
charge for fire assay’). In other cases more
explanation may be required, such as where there
is coarse gold that has inherent sampling
problems. Unusual commodities or mineralisation
types (eg submarine nodules) may warrant
disclosure of detailed information.

Sample data was derived from Havilah
reverse
circulation
(RC)
drillholes
as
documented in the table above.

RC assay samples averaging 2-3kg were riffle
split at 1 metre intervals. A small number of
samples from the lower parts of some holes
were too moist to go through the splitter and
were collected directly from the cyclone in
large plastic bags and grab sampled from
them using a scoop.

All RC drill samples were collected into pre-
numbered calico bags and packed into
polyweave bags by Havilah staff for shipment
to the assay lab in Adelaide.

Criteria JORC Code explanation Commentary
Drilling
techniques

Drill type (eg core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic,
etc) and details (eg core diameter, triple or
standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is
oriented and if so, by what method, etc).

All RC holes were drilled with a 121mm face
sampling bit. All samples were collected via
riffle splitting directly from the cyclone. A
small number of samples from the lower
parts of some holes were too moist to go
through the splitter and were collected
directly from the cyclone in large plastic bags
and grab sampled from them using a scoop.
Drill sample
recovery

Method of recording and assessing core and chip
sample recoveries and results assessed.

Measures taken to maximise sample recovery and
ensure representative nature of the samples.

Whether a relationship exists between sample
recovery and grade and whether sample bias may
have occurred due to preferential loss/gain of
fine/coarse material.

The sample yield and wetness of the RC
samples was routinely recorded in drill logs. A
small number of samples from the lower parts
of some holes were too wet to split.

The site geologist and Competent Person
consider that overall the results are acceptable
for interpretation purposes.

No evidence of significant sample bias due to
preferential concentration or depletion of fine
or coarse material was observed.

No evidence of significant down hole or inter-
sample contamination was observed in the
samples that were too wet to split.

Sample
recoveries
were
continuously
monitored by the geologist on site and
adjustments to drilling methodology were
made in an effort to optimise sample recovery
andqualitywhere necessary.
Logging
Whether core and chip samples have been
geologically and geotechnically logged to a level of
detail to support appropriate Mineral Resource
estimation, mining studies and metallurgical
studies.

Whether logging is qualitative or quantitative in
nature.

logging system with data uploaded directly
into an Excel spreadsheet and transferred to
a laptop computer.

All RC chip sample trays and some back-up
samples are stored on site at Kalkaroo.

Logging is semi-quantitative and 100% of
reported intersections have been logged.

Logging is of a sufficiently high standard to
support
any
subsequent
interpretations,
resource
estimations
and
mining
and
metallurgical studies.
Sub-sampling
techniques and
sample
preparation

If core, whether cut or sawn and whether quarter,
half or all core taken.

If non-core, whether riffled, tube sampled, rotary
split, etc and whether sampled wet or dry.

Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.

Measures taken to ensure that the sampling is
representative of the in situ material collected,

RC drill chips were received directly from the
drilling rig via a cyclone and were riffle split
on 1 metre intervals to obtain 2-3 kg samples.

Sampling size is considered to be appropriate
for the style of mineralisation observed. Assay
repeatability for gold and other metals has
not proven to be an issue in the past and is
checked with regular duplicates.

All

Assay data accuracy and precision was
continuously checked through submission of
field and laboratory standards, blanks and
repeats which were inserted at a nominal rate
of approximately 1 per 25 drill samples.

Several calico bags are placed in each
polyweave bag which are then sealed with
cable ties. The samples are transported to the
assay lab by Havilah personnel at the end of
each field stint.

There is minimal opportunity for systematic
tampering with the samples as they are not

All previous exploration data has been
integrated into Havilah’s databases.
Geology
Deposit type, geological setting and style of
mineralisation.

In
general
the
mineralisation
style
is
stratabound replacement and vein style
copper-gold mineralisation within Willyama
Supergroup rocks of the Curnamona Craton.

At Kalkaroo, the stratabound mineralisation is
uniformly distributed along more than 3 km
of strike that follows an arc around the 35
degree dipping northern nose of the Kalkaroo
south dome. It is hosted by an 80m-120m
thick mineralised horizon that is sandwiched
between psammitic footwall rocks and a thick
pelitic hangingwall sequence.

In part, the mineralisation is associated with
near-vertical, mineralised quartz vein breccia
fracture/fault fillings, which probably formed
channel ways for the mineralising fluids.
Interference
folding
resulted
in
dome
structures which probably acted as structural
traps for the rising mineralising fluids carried
by these vertical structures.

The mineralising events were associated with
iron-rich and sodium-rich alteration fronts,
which are manifest as widespread fine-
grained
magnetite
in
the
lower
sandy
formations and as pervasive albite alteration,
overprinted by later potassic veining and
alteration.

Erosion in the Mesozoic and Tertiary period
exposed the region to prolonged and deep
weathering.
Consequently,
the
original
sulphide
mineralisation
shows
typical
supergene enrichment features in its upper
part, caused by oxidation of the primary
sulphides in the weathering zone, forming a
soft clay rich rock called saprolite. This is
manifest in a sub-horizontal stratification of
the ore minerals from top to bottom:
1. Supergene free gold in saprolite, with
generally minor copper, recoverable by
gravity and cyanide leaching methods.
2. Native copper and gold in saprolite,
largely recoverable by gravity methods.
3. Chalcocite dominant with gold,
recoverable by conventional flotation.
4. Chalcopyrite dominant with gold and
locally rich molybdenum, recoverable by
conventional flotation.

above sea level in metres) of the drill hole
collar
o

If the exclusion of this information is justified on
the basis that the information is not Material and
this
exclusion
does
not
detract
from
the
understanding of the report, the Competent Person
should clearly explain why this is the case.
Data
aggregation
methods
In reporting Exploration Results, weighting
averaging techniques, maximum and/or minimum
grade truncations (e.g. cutting of high grades) and
cut-off grades are usually Material and should be
stated.
Where aggregate intercepts incorporate short
lengths of high grade results and longer lengths of
low grade results, the procedure used for such
aggregation should be stated and some typical
examples of such aggregations should be shown in
detail.
The assumptions used for any reporting of metal
equivalent values should be clearly stated.

Not applicable as not reporting mineral
resources.
Relationship
between
mineralisation
widths and
intercept
lengths
These relationships are particularly important in the
reporting of Exploration Results.
If the geometry of the mineralisation with respect to
the drill hole angle is known, its nature should be
reported.
If it is not known and only the down hole lengths are
reported, there should be a clear statement to this
effect (e.g. ‘down hole length, true width not known’).

Downhole lengths are reported. Drillholes are
typically oriented with the objective of
intersecting
mineralisation
as
near
as
possible to right angles, and hence downhole
intersections in general are as near as
possible to true width.

For
the
purposes
of
the
geological
interpretations and resource calculations the
true widths are always used.
Diagrams Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for
any significant discovery being reported. These
should include, but not be limited to a plan view of
drill hole collar locations and appropriate sectional
views.

Not applicable as not reporting a mineral
discovery.
Balanced
Reporting

Accuracy and quality of surveys used to locate drill
holes (collar and down-hole surveys), trenches,
mine workings and other locations used in Mineral
Resource estimation.
Where comprehensive reporting of all Exploration
Results is not practicable, representative reporting
of both low and high grades and/or widths should
be practiced to avoid misleading reporting of
Exploration Results.

Not applicable as not reporting mineral
resources.
