20% INCREASE IN KARLAWINDA MINERAL RESOURCE TO 1.3MOZ OF GOLD

Potential for significant increase of Bibra open pit reserves and Project mine life extension

HIGHLIGHTS

ASX ANNOUNCMENT

13 November 2017

  • A modest exploration and resource drilling program undertaken during the period May to July 2017 has delivered a substantial increase in the Mineral Resource estimate for Capricorn’s 100%owned Karlawinda Gold Project in WA’s Pilbara region.

  • The November 2017 Mineral Resource, reported at a 0.5g/t Au cutoff grade and a A$1750/oz gold price is (see Table 1):

  • 38.3 million tonnes @ 1.1g/t Au for 1,326,000 ounces of gold

  • This represents a 20% increase (212,000 ozs) from the April 2017 Mineral Resource estimate and a 100% increase in resources since acquisition of the Project in February 2016. Approximately 25% of the resource is now in the highest confidence Measured Resource category.

  • The resource growth at the Bibra deposit demonstrates the outstanding endowment potential of the Karlawinda Gold Project, as ongoing exploration continues to define a significant large-scale Archaean gold system.

  • A key result is the significant increase in resource within the A$1500/oz optimised pit shell which formed the basis for the open pit mine design and August 2017 Ore Reserve estimate. The total ounces within this selected pit shell previously reported to within 1.4% of the final pit design and subsequent Ore Reserve estimate.

  • The November 2017 A$1500/oz optimised resource estimate is: o 27.35 million tonnes @ 1.12g/t Au for 985,600 ounces

  • The new A$1500/oz optimised resource includes 897,400 ounces in the Measured and Indicated categories and is an increase of 262,600 ounces from the April 2017 A$1500/oz optimised resource of 21.1 million tonnes @ 1.07g/t Au for 723,000 ounces.

  • There is a high-probability that a large proportion of these additional resources within the A$1500/oz optimised pit shell will convert into an upgraded reserve estimate in the near term. This will result in a material increase in the mine life of the Project.

  • Substantial ongoing resource growth is expected in the coming months as open extensions of mineralised domains are further drill tested and additional infill drilling provides sufficient density in areas that are currently unclassified.

MANAGEMENT COMMENT

Capricorn’s Executive Chairman, Heath Hellewell, said: “At Karlawinda, the Bibra deposit continues to reveal itself as part of a very significant Archaean gold system. We continue to achieve outstanding success in growing the resource base at a very low discovery cost per ounce. Since acquiring the Project at the beginning of last year, we have now doubled the resource base and improved our understanding of the controls on mineralisation. We are very well placed to deliver further significant increases in the Project’s resources with drilling in the coming months.

“We recently reported the results of our Feasibility Study which confirms the robust economics of the Karlawinda Gold Project and supports the development of a significant new Western Australian gold mine. That view is clearly enhanced by the delineation of these additional resources that we anticipate will result in a material increase in the reserve in the near term. We expect that our exploration efforts both near-mine and regionally will continue to deliver on the Project’s growth potential and significantly extend the mine life.”

KARLAWINDA RESOURCE UPDATE

Capricorn Metals Limited (ASX: CMM) is pleased to advise that it is continuing to achieve significant growth in the gold resource inventory at its 100%-owned Karlawinda Gold Project in WA (Figure 1) after delivering substantial increase in the JORC 2012 Mineral Resource, which now stands at over 1.3 million ounces of gold .

Following the incorporation of recent resource drilling data and the application of high confidence mine operating cost estimates directly derived from the recently completed Feasibility Study (“FS”), the total Measured, Indicated and Inferred Mineral Resource has increased to 38.3 million tonnes grading 1.1g/t Au for 1,326,000 ounces of contained gold.

This represents a 20% increase from the April 2017 Mineral Resource and a 100% increase since Capricorn acquired the Project in early 2016 (see Tables 1 and 2).

Key Points:

  • An additional 10,000 metres of drilling information has been incorporated into this resource update.

==> picture [43 x 48] intentionally omitted <==

Page 2 of 18

  • The reported resource is constrained by a A$1750/oz optimised pit shell which applies detailed operating cost estimates taken directly from the recently completed Feasibility Study (“FS”).

  • 83% of the resources are now classified in the high confidence Measured and Indicated categories.

  • A Measured Resource totalling 8.3 million tonnes @ 1.25g/t Au for 334,300 ounces has been reported for the first time.

  • A significant increase in resource has been estimated within the A$1500/oz optimised pit shell. The A$1500/oz optimized pit shell was the basis of the open pit mine design and August 2017 Ore Reserve estimate. Total ounces within this selected pit shell previously reported to within 1.4% of the final pit design and Ore Reserve estimate announced to the ASX on 7[th] August 2017.

The total estimated Mineral Resource contained within the A$1500/oz pit shell is as follows:

Measured and Indicated: 24.8 million tonnes @ 1.13g/t Au for 897,400 ounces Inferred: 2.55 million tonnes @ 1.08g/t Au for 88,200 ounces TOTAL: 27.35 million tonnes @ 1.12g/t Au for 985,600 ounces

With additional drilling, the Inferred Resource component is expected to upgrade to a higher confidence classification and it is likely that a large proportion of these additional resources will convert into an upgraded reserve estimate in the near term with a resultant increase in Project mine-life.

  • The impact of being able to add further resource ounces in the shallow hanging wall position of the Bibra Open Pit along the Portrush Zone has resulted in the A$1500 optimised pit shell driving deeper and capturing previously defined Indicated resources (Figure 2).

  • Importantly, an additional 77,000 ounces of oxide and transitional resources have been added to the total resource. This material can potentially be processed early in the mine life at a higher rate with substantial benefits to the Project’s economics.

  • Further additions to the Bibra resource are expected with ongoing exploration as several mineralised domains remain open or drilling is not yet of a density to allow classification.

  • Resource expansion and exploration drilling programs are scheduled to re-commence in mid-November 2017 and will continue into 2018.

NEXT STEPS

This result continues to demonstrate the ongoing resource growth potential of the Bibra Gold Deposit and its ability to support a long-life mining operation.

The next phase of drilling will focus on the expansion of key mineralised domains that have not yet been fully defined. In particular, a zone of higher-grade mineralisation has been identified on the western edge of the Bibra Pit along the Portrush Zone that has significant growth potential (Figure 2). Previous results from this zone, which are open down-dip and along strike include (see ASX announcement dated 3 August 2017 for details):

  • KBRC1038 25m @ 2.28g/t Au

  • KBRC0953 28m @ 1.47g/t Au

  • KBRC0907 10m @ 1.41g/t Au and 10m @ 1.78g/t Au

  • KBRC0951 14m @ 2.06g/t Au

Additional work will also focus on:

  • Further targeted in-fill drilling of unclassified mineralised domains, which will enable this mineralisation to be included in future resource estimations;

  • Testing of a series of highly ranked exploration targets across the greater Karlawinda Gold Project; and

  • An updated reserve estimate based on this current resource and ongoing exploration, which is expected to be completed early in the second Quarter of 2018.

Sampling
techniques

Nature and quality of sampling (e.g. 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 (e.g. ‘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 (e.g.
submarine nodules) may warrant disclosure of
detailed information.
Drilling at the Bibra deposit has been completed by two
companies Independence Group (IGO) and Capricorn
Metals Group (CMM). The methods of collection have
been very similar in terms of sampling procedures, drilling
methods and sampling quality.
For drilling between 2017 & 2015 RC drilling the standard
method of sample collection included the following:
2kg - 3kg samples were split from dry 1m bulk samples.
The sample was initially collected from the cyclone in an
inline collection box with independent upper and lower
shutters. Once the metre was completed, the drill bit was
lifted off the bottom of the hole, to create a gap between
sample, when the gap of air came into the collection box
the top shutter was closed off. Once the top shutter was
closed, the bottom shutter was opened and the sample
was dropped under gravity thorough a Metzke cone
splitter. Once drilling reached fresh rock a fine spray of
water was used to suppress dust and limit the loss of fines
thorough the cyclone chimney. A second 2kg-3kg sample
was collected at the same time the original sample. This
sample has been stored on site. These duplicate samples
have been retained for follow up analysis and testwork.
The bulk sample of the main ore zone was discharged from
the cyclone directly into green bags. The bulk sample from
the waste was collected in wheelbarrows and dumped into
neat piles on the ground.
During the sample collection process, the cone split,
original and duplicate calico samples and the reject green
bag samples were weighed to test for bias’s and sample
recoveries. The majority of the check work was undertaken
through the main ore zones.
Field duplicates were collected at a ratio of 1:20 through
the mineralised zones and collected at the same time as
the original sample through the B chute of the cone splitter.
OREAS certified reference material (CRM) was inserted at
a ratio of 1:20 through the mineralised zone. The grade
ranges of the CRM’s were selected based on grade
populations and economic grade ranges.
For the diamond drilling- NQ core was half cut in half using
a corewise automatic core saw.
In 2012, RC samples were collected for 1m intervals using
a rig-mounted cone splitter. Samples were to be 12½%
from each of the two sample chutes and 75% reject
collection. Wet samples were grab sampled and recorded
as such in the database, few were within mineralised
zones. NQ core was half-core sampled and HQ/HQ3 core
was initially quarter-core sampled. Issues with quarter-
coring in the regolith with complete disintegration of the
sample and loss of material were identified, and reverted
to half-core sampling with less water for better sample
quality. Standards, blanks and field duplicates were
inserted into each batch of samples submitted to the
laboratory.

Page 7 of 18

Criteria JORC Code explanation Commentary
Prior to 2011 the standard method of sample collection
included the following:
Prior to 2011, RC samples were collected at the rig using
a cone splitter that split the 1m cuttings into 87½% &
12½% splits. RC samples were originally composited to
2m by taking scoops from each of the 1m interval and
submitted to Genalysis for sample preparation and
analysis. Samples that returned values >0.5g/t Au were
submitted as 1m samples to Genalysis. In 2011, RC
samples were not composited and 1m interval samples
were sent directly to Genalysis. A rig mounted cone
splitter was used to split the samples into 87½% & 12½%
splits. NQ2 core was half-core sampled and PQ and PQ3
core was quarter-core sampled using a manual core-
cutting diamond saw without water in the oxide zone. The
dry cutting was to prevent loss of clays for the metallurgical
samples. Sample quality is considered to be good and all
RC drilling within the resource area was dry.
Drilling
techniques

Drill type (e.g. core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic, etc.)
and details (e.g. 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.).
In 2017 drilling, 1 Ranger Drilling drill rig was used to drill
140 RC drilling holes for 13,460m. The rig consisted of a
Schramm track mounted RC rig with 1150cfm x 350psi on
board compressor, an Air-research 1800cfm x 900psi on
board Booster, and a truck-mounted Sullair 900cfm x
350psi auxiliary compressor.
In 2016, 3 Ranger Drilling drill rigs, were used to drill 541
holes for 63,676m, including 2 x DRA600 RC rig with
1350cfm@500psi compressor with a 1800cfm x 800psi
booster and 900cfm, 350psi auxiliary and 1 KWL350 truck
mounted RC Rig with 1050cfm x 350psi on board
compressor, Sullair 1050cfm @ 350psi auxiliary
compressor and Air-research 1150cfm x 350psi booster.
The holes were drilled using a nominal 135mm diameter
face sampling bit, and to limit the hole deviation 4metre
thick wall rod and top and bottom stabilisers were used.
In 2016, 35 PQ/HQ diamond holes were drilled by
Westralian Diamond Drillers (Kalgoorlie) for 4,610m using
two KL900 rig's.
Drilling in 2015, 46 RC holes have been completed by
reverse circulation using Ranger Drilling DRA600 RC rig
with 1350cfm@500psi compressor with a 1800cfm x
800psi booster and 900cfm, 350psi auxiliary.
In 2012, 60 RC drillholes for 8409m and RC precollars for
534.8m were drilled by Blue Spec Mining using a KLBS900
Multipurpose rig with 4inch drill rods and face sampling
5inch bits. Two HQ3/NQ diamond holes were drilled by
Blue Spec for 305.3m using the Multipurpose rig and 24
HQ/HQ3 diamond holes were drilled by Foraco for
3158.6m using a UDR1000 truck-mounted rig. Core from
the Foraco drilling was oriented using an Ezymark
orientation tool. Numerous aircore holes have been drilled
into the project but these were not used in the resource
estimate
In 2011, 78 RC drillholes for 14,103m were drilled by
Profile Drilling Services using a Schramm RC rig and 11
diamond holes (two with RC precollars, precollars drilled
by Profile Drilling Services) drilled by Drill West using a
Boart Longyear LF90D skid mounted rig. Core diameter
was PQ3 and PQ to provide samples for metallurgical
testwork and to also twin RC drillholes. Core was oriented
(where possible) using a Reflex ACE orientation
instrument.

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.
During the sample collection process, the cone split,
original and duplicate calico samples and the reject green
bag samples were weighed to test for bias’s and sample
recoveries. The majority of the check work was undertaken
through the main ore zones. From this process showed
that the majority of ore grade samples had recoveries
greater than 80%
Once drilling reached fresh rock a fine spray of water was
used to suppress dust and limit the loss of fines thorough
the cyclone chimney.
At the end of each metre the bit was lifted off the bottom to
separate each metre drilled.
The majority of samples were of good quality with ground
water having minimal effect on sample quality or recovery.
From the collection of recovery data, no identifiable bias
exists.
In 2012, RC sample recovery was variable, particularly in
the regolith. Sample quality was recorded during logging
and qualitative recovery codes were assigned to each
sample. Sample weights were measured for each
component of RC hole cuttings in mineralised zones, with
results showing that regolith samples were generally poor
quality (both under and over-weight samples) and quality
was moderate in the other zones.
Core was reassembled for mark-up and was measured,
with metre marks and down-hole depths placed on the
core. Depths were checked against driller’s core blocks
and discrepancies corrected after discussion with drillers.
Core loss was recorded in the geological log.
Core recovery was generally good. RC sample recovery
prior to 2012 has been logged as good with samples kept
dry during drilling.
There is no obvious relationship between sample recovery
and grade.
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.
Core (or costean, channel, etc.) photography.

The total length and percentage of the relevant
intersections logged.
Reverse circulation chips were washed and stored in chip
trays in 1m intervals for the entire length of each hole.
Chips were visually inspected and logged to record
lithology, weathering, alteration, mineralisation, veining
and structure.
Data on rocktype, deformation, colour, structure,
alteration, veining, mineralisation and oxidation state were
recorded. RQD, magnetic susceptibility and core
recoveries were recorded.
RC chips sample quality and weights were also recorded,
including whether wet or dry
Logging is both qualitative and quantitative or semi-
quantitative in nature. Core was photographed both dry

Whether sample sizes are appropriate to the grain
size of the material being sampled.
For holes KBRC284 to KBRC1045. Samples were split
from dry, 1m bulk sample via a cone splitter directly from
the cyclone.
The quality control procedure adopted through the process
includes:
Weighing of both Calico samples and reject sample to
determine sample recovery compared to theoretical
sample recovery and to check sample bias through the
splitter.
Field duplicates were collected at a ratio of 1:20 through
the mineralised zones and collected at the same time as
the original sample through the B chute of the cone splitter.
OREAS certified reference material (CRM) was inserted at
a ratio of 1:20 through the mineralised zone. The grade
ranges of the CRM’s was selected based on grade
populations and economic grade ranges
The duplicate and CRM’s were submitted to the lab using
unique sample ID’s.
A 2kg – 3kg sample were submitted to Intertek laboratory
in Maddington in WA.
Samples were oven dried at 105°C then jaw crushed to -
10mm followed by a Boyd crush to a nominal -2mm.
Samples were rotary split to 2.5kg. Samples were then
pulverised in LM5 mills to 85% passing 75μm under
sample preparation code EX03_05 which consists of a 5
minute extended preparation for RC/Soil/RAB. The
extended time for the pulverisation is to improve the
pulverisation of samples due to the presence of garnets in
the samples.
All the samples were analysed for Au using the FA50/MS
technique which is a 50g lead collection fire assay.
All core has been cut into half or quarter core for sampling.
For early drillholes KBRC005-010, RC composite samples
(2m) were submitted to Genalysis where they were sorted,
dried and the total sample pulverised in a single stage mix
and grind if the sample mass was <3kg. Samples >3kg
mass were riffle split using a 50:50 splitter and one half
pulverised. Samples were analysed for Au using an aqua
regia digestion (AR10/OM) of a 10g pulp sample with ICP-
MS determination. Samples that returned values >0.5g/t
were submitted to Genalysis as 1m resplit samples and
prepared in a similar manner as the composites.
For drillholes from KBRC011 to KBRC283 (2009-2012), no
compositing took place, 1m split RC samples and core
samples were submitted to Genalysis for fire assay.
Samples were oven dried at 105°C then jaw crushed to -
10mm followed by a Boyd crush to a nominal -2mm.
Samples were rotary split to 2.5kg (2012 drilling). Samples
were then pulverised in LM5 mills to 85% passing 75µm.
All the samples were analysed for Au using the FA50/AAS
technique which is a 50g lead collection fire assay with
analysis by Flame Atomic Absorption Spectrometry. The
fire assay method is considered a suitable assaying
method for total Au determination. The aqua regia
digestion results (used for samples that were <0.5g/t Au)
may not allow for total Au determination in the transition
and fresh rock zones. Aqua regia samples are only
present for 5 holes and therefore represent only a very
small percentage of the samples.

Geological
interpretation

Confidence in (or conversely, the uncertainty of)
the geological interpretation of the mineral deposit.

Nature of the data used and of any assumptions
made.

The effect, if any, of alternative interpretations on
Mineral Resource estimation.

The use of geology in guiding and controlling
Mineral Resource estimation

The factors affecting continuity both of grade and
geology.
Confidence in the geological interpretation is good.
Stratigraphy is consistent and can be correlated
between holes and along strike.
Geological logging and structural measurements from
drillholes have been used to construct the geological
model and northern fault. Sections were interpreted,
digitised and a 3D wireframe model constructed.
Geological continuity has been assumed along strike
and down-dip.
The geological interpretation is robust. The geological
model was built by on the ground geologists who logged
and relogged and interpreted the geology to ensure the
geological interpretation was consistent. With the
current drill spacing it is unlikely that an alternative
interpretation will develop. There is currently sufficient
drilling to map the stratigraphic units and laterite zone.
The geological model has been used to guide
mineralisation
envelopes
and
subsequent
mineralisation wireframe modelling.
Geological continuity has been assumed along strike
and down-dip based on reasonably the drilling data. In
general, continuity both geologically and grade-wise
within a 0.3ppm shell is good. Grades and thickness are
more consistent down-dip than along strike.
Dimensions
The extent and variability of the Mineral Resource
expressed as length (along strike or otherwise),
plan width, and depth below surface to the upper
and lower limits of the Mineral Resource.
The Bibra mineralisation wireframes have been
projected down-dip based on wider spaced drilling
intercepts; however, this extrapolation has been
removed from the resource estimate by limiting the
reported tonnes and grade to within a conceptual
optimal pit shell ($2000/oz Au). The laterite zone
modelled was 900m along strike and 230m wide in the
NE widening to 560m in the southern half. It ranges
from 1.7m to 14m in vertical thickness.
The primary mineralisation extends below the laterite
zone for a further vertical depth of 270m.
The transition/fresh rock boundary is about 60m below
surface. The primary mineralisation has 4 main sub-
parallel zones and several smaller zones. The main
zone is 900m long (N-S) and 980m wide (horizontal
width) at its widest part in the north, tapering to 40m
wide (horizontal width) at the southern end. The
thickness of the main primary mineralisation zone
ranges from 1.7m vertical thickness to 30m in the
thickest part.

minimum of 3 for the third pass.
No mining has occurred at Bibra.
No assumptions have been made regarding by-

No deleterious elements are known or expected.
Only Au has been modelled.
The geological interpretation was used to control
mineralisation modelling and to assign densities to rock-
types.
Top-cuts were established after a study of statistics,
histograms and log-probability plots for the main
domains. Domains which had CV’s above 2 were top
cut, until the CV for the domain was below a CV of 2. 25
samples were cut.
The block model is checked visually in Surpac and
Micromine by comparing drillhole assays with block
grades.
Swath plots are generated to compare block grades
with sample composite grades on a sectional and plan

Moisture
Whether the tonnages are estimated on a dry
basis or with natural moisture, and the method of
determination of the moisture content.
Tonnages have been estimated on a dry basis. Core
samples in the oxide zone have been measured for
density after drying and coating at an independent
laboratory and downhole gamma used in the 2016
program. 2012 density samples in the Transition and
fresh rock samples have been tested uncoated on site
after sun-drying, and added to the database of samples
tested by the independent laboratory. Measurements
in 2012 confirmed earlier density measurements for
rocktype and oxidation. 2016 bulk density samples in
the oxide, transitional and fresh material were
measured at Intertek laboratories in Perth.

Test work was completed during 2017 using 32
composite samples from 779metres of core.
The Bibra ore is classified as free milling, with a high
gravity recoverable gold component (up to 45%).
Overall, gravity plus leach gold recoveries are in the
range of 93% to 96%. The Bibra ore is relatively clean,
with minimal to no cyanide or oxygen consuming
gangue minerals present in the ore, leading to low
residual WAD cyanide levels (<50ppm) in the leach
circuit tailings solution.
Environmental
factors
or
assumptions

Assumptions made regarding possible waste
and process residue disposal options. It is
always necessary as part of the process of
determining reasonable prospects for eventual
economic extraction to consider the potential
environmental impacts of the mining and
processing operation. While at this stage the
determination
of
potential
environmental
impacts, particularly for a greenfields project,
may not always be well advanced, the status of
early
consideration
of
these
potential
environmental impacts should be reported.
Where these aspects have not been considered
this should be reported with an explanation of the
_environmental assumptions made. _
Waste rock from open pit operations would be placed in
a waste rock landform adjacent to open pit operations,
progressively contoured and revegetated throughout
mine life. Process plant residue would be disposed of in
a surface tailings storage facility (TSF). Adoption of an
upstream, central decant design would utilise mine
waste material for dam wall construction and facilitate
water recovery to supplement process water
requirements. It is expected that sufficient volumes of
oxide material, able to be made sufficiently
impermeable, will be available in the overburden stream
to enable acceptable TSF construction.
Bulk density
Whether assumed or determined. If assumed,
the basis for the assumptions. If determined, the
method used, whether wet or dry, the frequency
of the measurements, the nature, size and
representativeness of the samples.

The bulk density for bulk material must have
been measured by methods that adequately
account for void spaces (vugs, porosity, etc),
moisture and differences between rock and
alteration zones within the deposit.

Discuss assumptions for bulk density estimates
used in the evaluation process of the different
materials.
Densities were based on measured densities sorted by
rock type and oxidation state.
In 2016 drill program transitional and fresh samples
core samples were analysed by water immersion
method by Intertek laboratories.
In the 2012 core drilling program, all samples sent for
analysis from the transition or fresh rock zones were
density measured. Density determination by the water

Some assumptions have been made on rocktypes away

The basis for the classification of the Mineral
Resources into varying confidence categories.
