Sources of diamonds
⧫ Kimberlite is the primary source of
diamonds (lamproite is another)
⧫ Diamonds are made of pure
carbon. Diamond and graphite
are “allotropes” of carbon
⧫ Diamonds formed in the upper
mantle, under particular
conditions of temperature and
pressure (“Diamond Stability
Field”)
⧫ Kimberlite magmas (the vehicle)
transported diamonds from the
DSF to/near surface
⧫ Erosion of kimberlites has created
secondary deposits
(alluvial/eluvial and marine)

INCREASING COSTS and TIMEFRAMES
DECREASING UNCERTAINTY and RISK
⧫ Investors’ appetite grows with
confidence, as do costs and time
frames
⧫ Compressing timeframes without
compromising on quality
⧫ Maximising optionality: phased
approach
⧫ Reliable resource models
⧫ Deep expertise and technology are
key differentiators
⧫ Extract value or cut losses early
Mapping,

Soil Sampling
⧫ Soil (loam) sampling a
good first pass
reconnaissance and
follow-up exploration
tool.
⧫ Abundant kimberlitic
minerals: garnet,
spinel and chromium
diopside proximal to
the kimberlite.
⧫ Strong halo effect:
coarse grains don’t
tend to travel far.

Ground Geophysics - Magnetics
⧫ Magnetics tend to
chiefly outline the
dolerite and not
kimberlite dykes as the
latter are only weakly
magnetic.
⧫ Magnetic susceptibility
readings from drill core
show that on average,
the kimberlite has a
susceptibility of 0.47SI
with a maximum of 1.3SI
⧫ Quick and relatively
cheap technique.
10
Reference: Geofocus, 2020
11. AWDC/GIBS 2024
Ground geophysics - Gravity
⧫ Gravity is used where
we believe there is a
kimberlite blow.
⧫ Blows tend to produce
gravity lows.
⧫ It is a more time
consuming and
complex technique
and thus more costly
so is restricted to
specific targets.
11
Reference: Geofocus, 2020
12. AWDC/GIBS 2024
Drone Surveys
⧫ Detailed drone surveys
undertaken over much of
the property.
⧫ The aim of these surveys
was to:
⧫ Provide accurate
georeferences for
groundwork, such as drilling
and geological mapping.
⧫ Assess vegetation
anomalies.
⧫ The tool was also helpful in
the production of videos
for public relations
purposes.

13. AWDC/GIBS 2024
Precision Structural Mapping
⧫ Subterrane of the UK uses a
combination of precision field
structural geological
measurements in combination with
detailed ground geophysics to
identify targets.
⧫ Targets are defined as buried or
partially buried (potential) blows.
⧫ This is still very much work in
progress and has been
considerably delayed due to
Covid related travel restrictions.

Spectral analysis
⧫ Terramodelling Services of Canada used
machine and deep learning to delineate
spectral anomalies from European Space
Agency Sentinel 1 / 2 and ASTER data.
⧫ The following were assessed:
⧫ Structure
⧫ Topography
⧫ Elevation and displacement
⧫ Hydrothermal alteration
⧫ Epidote and chlorite alteration
⧫ Radon affected vegetation
⧫ Ferrous and ferric oxide spectra
⧫ ASTER mica and serpentine spectra
⧫ Satellite and UAV spectral analysis, combined
with machine and deep learning, has
fundamentally changed the remote sensing
landscape in the last 5-years.

Drilling – RC Percussion
⧫ Reverse Circulation (‘RC’) drilling
follows positive sampling and
ground geophysical work.
⧫ Both angle and vertical holes
were drilled.
⧫ The diameter of the holes was
140mm and a continuous 1m
sample was taken and bagged.
⧫ Portions of these samples were
washed and geologically logged.
⧫ Kimberlitic indicators and
diamonds were recovered from
select samples down to +0.3mm
following screening, separation
using Tetrabromoethane (TBE’)
and hand sorting.

Drilling - Core
⧫ Core drilling was carried
out where there was a
requirement for more
detailed geological
data.
⧫ The core was subjected
to detailed independent
petrographic work.
⧫ Samples from the core
were also taken for
microdiamond analyses.
16
Reference: Georoc, 2017
17. AWDC/GIBS 2024
Bulk Sampling
⧫ Bulk sampling was undertaken in an
area where the kimberlite dyke swelled.
⧫ The purpose of the bulk sampling was to
produce sufficient macro diamonds for
preliminary grade and valuation
models.
⧫ The samples were processed at an
independent bulk sampling plant which
included crushing, scrubbing, screening,
dense media separation (‘DMS’), X-Ray
and grease recovery.
⧫ The area was fully rehabilitated on
conclusion of the exercise.

Mineral Chemistry
⧫ Around 54% of garnets fall into the G9/G5 category (garnets
that originate from lherzolites and websterites).
⧫ 19% fall in the G10 field (garnets originating from harzburgites)
and 7% garnets in the G10D (diamond inclusion) field.
⧫ The G10D garnets, plotting within the diamond inclusion field,
indicate the possibility of peridotitic diamonds sampled by the
kimberlite from which this sample has been taken.
⧫ 20% of the garnets (with Cr2O3 less than 2%) fall in the G3 and
G4 (eclogitic and megacrystic garnet) fields.
⧫ There is a population of eclogitic Group 1 garnets which
suggests the source may also contain diamonds of eclogitic
origin.
⧫ Recent work by Tappe suggests that the kimberlite could be
a hybrid Group 1 / 2 variety.
18
References: Marshall & Campbell, 2018, Tappe 2021
19. AWDC/GIBS 2024
Petrography
⧫ All kimberlite samples are Group 2 variety, coherent
hypabyssal kimberlites with mineralogies dominated
by calcite and phlogopite but with accessory apatite
and in some samples monticellite, clinopyroxene and
richterite amphibole. Fine grained perovskite and
opaques are also present.
⧫ All kimberlite samples can be classified as apatite-
bearing calcite phlogopite kimberlites.
⧫ For comparison, the Marsfontein pipe has two
kimberlite phases – a monticellite phlogopite phase
and a phlogopite monticellite phase.
⧫ Where the dyke gets wider variable mineralogy is
seen, with the crystallization of accessory
clinopyroxene, amphibole richterite and monticellite.

Diamonds: Macro & Micro
⧫ Select core samples were
taken for microdiamond
work and processed at an
independent laboratory.
⧫ A trench was excavated
for the recovery of
macrodiamonds and
processed at an
independent bulk sample
processing facility.
⧫ Micro-macrodiamond
modelling was performed
to derive a Total Content
Curve.
⧫ The macro diamonds were
described and valued.

Geological Modelling
⧫ Detailed ground geophysical work
supplemented by drilling results has
enabled kimberlite modelling using
Inversion and Forward Modelling
Techniques.
⧫ Estimated volume so far of 72,000m3.
⧫ This work is being expanded to cover
both the River and River Extension
blows.
⧫ This technique has significant
advantages over just using the drill data
especially due to the complexity of the
kimberlite root zone structures and uses
all available data.

Competent Persons Report (‘CPR’)
⧫ Published in February 2018.
⧫ “Based on the exploration results to date, exploration
targets have been highlighted with the following potential:
⧫ The undiluted raw in-situ grade of the kimberlite dyke sample is
estimated between 46-74 cpht (1mm bcos). By contrast, the
micro macro models return a range of total content model
grade that falls between 54 to 88 cpht at bottom cut off size of
+3 DTC diamond sieve (1mm).
⧫ Wide range of modelled diamond values at USD120-220/ct (at
1mm bcos).
⧫ Potential volumes of some 450,000 – 470,000m3. Using the
estimated 2.6g/cm3 density calculated by Vutomi, this may
reflect target tonnages of over some 1.2MT to 100m depth.”

Diamond Mining
KIMBERLITE
⧫ High set up costs
⧫ Open pit and/or underground
operations
⧫ Grade, diamond distribution can be
constrained with sampling and
modelling
⧫ In the past crushers broke the larger
stones
⧫ High resource confidence can mitigate
uncertainty
ALLUVIAL DEPOSITS
⧫ Lower start-up costs
⧫ Low grade, high variability
⧫ High uncertainty
⧫ High-volume, low-cost approach
⧫ Generally, less large (high-value)
diamonds
⧫ Volumes are key
⧫ Metallurgy and diamond value
management
⧫ Primary and secondary diamond
deposits can become economic
mines.
⧫ Perception that alluvials are more
suited to smaller operators (juniors)
and kimberlites to larger ones (mid-
tier and majors).
⧫ Majority of juniors own kimberlite
operations.
⧫ Majors like De Beers & Alrosa have
been running large-scale alluvial
operations.
⧫ Offshore marine deposits along
Namibian coast formed by

Government incentives to exploration
Canada (1,600 juniors) Australia (600 juniors) South Africa (12 juniors)
The Flow-Through Share (‘FTS’) regime is
a tax-based financing incentive
whereby a company agrees to incur
eligible exploration and development
expenses which are “renounced” to the
shareholders who claim an income tax
deduction. It was introduced in 1958.
The Junior Mineral Exploration Incentive
(‘JMEI’) allows eligible companies to
give up a portion of their losses from
greenfields exploration expenditure to
generate tax credits in favour of
Australian resident shareholders who
buy newly issued shares.
Target to attract 5%of global
exploration dollars. How?
JSE’s Junior Mining Accelerator
Programme codirected by Mincosa.
Lacking the well-established, well-
entrenched venture capital mindsets of
Canada and Australia.
⧫ FTS has enabled juniors to raise equity
at a premium to their share price,
attracting capital to the riskiest stage
of the mining/exploration cycle.
⧫ The FTS regime turned Canadian
capital markets into the destination of
choice for mining companies.
⧫ FTS financings play a counter-cyclical
role during exploration downturns.
⧫ Explorers have limited time to apply,
raise capital and spend the money,
for investors to be eligible for capped
exploration credits.
⧫ Additional incentives exist, e.g.
Exploration Incentive Scheme (‘EIS’) in
Western Australia and Accelerated
Discovery Fund (‘ADF’) in South
Australia.
⧫ Section 12J, modelled on the UK
Venture Capital Trust regime to boost
exploration funding in South Africa,
was abolished in February 2021,
having failed to deliver the
anticipated benefits to exploration.
⧫ Flow-through share model first
mooted 10 years ago; presented to
National Treasury in 2020; now being
re-considered.

Onerous regulatory and ESG compliance
47
⧫ Relevance and transparency of regulatory reporting is critical to
attracting junior funding, yet onerous.
⧫ Investors increasingly value a company’s ability to manage
environmental, social and governance (ESG) factors.
⧫ Carbon neutrality is high on ESG agenda.
⧫ ESG factors even more prominent since the start of the war in Ukraine
(ethically sourced diamonds/traceability).
⧫ Mineral reporting requirements vary across jurisdictions.
⧫ Reporting frequency is quarterly on TSX, six-monthly on AIM and ASX.
⧫ Minimum standards for public reporting by Competent Persons
(‘CPs’) are set by professional Codes of Practice.
⧫ Most standards share common codes and guidelines, e.g. CIM,
JORC, SAMREC.

⧫ Value of exploration for long-
term growth is well-accepted.
⧫ However, exploration spend is
regarded as discretionary in
the short term.
⧫ Majors have pulled back in
recent years.
⧫ Juniors’ exploration spend
constrained by tougher

Traditional sources of funding
50
Chart modified after PwC, 2013
⧫ Public equity was once the chief source of
funding for mining deals.
⧫ Many of today’s majors were established
through capital market funding.
⧫ Poor confidence in exploration and
competition from new investment
categories have changed the landscape.
⧫ Capital markets are not “junior-friendly”.
⧫ Private equity funds have less onerous
requirements, but money is more expensive.
⧫ Debt financing only becomes accessible at
advanced development or mining stage.
⧫ Junior and mid-tier operators need investors
with risk appetite and flexible processes.
