MASSIVE INCREASE IN MINERAL RESOURCES AT TORMIN WITH MAIDEN RESOURCE AT WESTERN STRANDLINE

  • High-grade resource of 106 million tonnes at 12.4% Total Heavy Minerals (“THM”)[1] , containing 13 million tonnes in situ Heavy Mineral at Western Strandline.

  • 22.8 million tonnes at 20.9% THM located within the expanded Mining Right area of the Western Strandline (22% of the total estimated resource) immediately available for mining.

  • Over 85% of the Mineral Resource in the expanded Mining Right area is classified as Measured and Indicated. Mineralisation is continuous and open along strike.

  • 10,000m step out and infill drilling program to continue at Western and Eastern Strandlines

Mineral Commodities Ltd (“MRC” or “the Company”) and its empowerment partner, Blue Bantry Investments 255 (Pty) Ltd, are pleased to announce a maiden JORC Resource for the Western Strandline of its Inland Strands. The Western Strandline spans the Section 102 Amended Mining Right (“S102 Mining Right”) (WC 30/5/1/2/2/10108MR) and Prospecting Right (WC 30/5/1/1/2/10262PR) owned by the Company’s 50% owned South African subsidiary, Mineral Sands Resources (Pty) Ltd (“MSR”).

The Mineral Resource was prepared in accordance with the Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (“JORC Code (2012)”) and is estimated at 106 million tonnes at 12.4% THM in the categories of Measured, Indicated and Inferred using a 2% THM cut-off grade and independently peer reviewed by Wardell Armstrong International. Pursuant to ASX Listing Rule 5.8.1, and in addition to the information contained in the body of this release, please refer to Appendix 1 JORC Table 1 for additional information, which is material to understanding the estimates of the Mineral Resources.

Executive Chairman Mark Caruso said, “ This is a transformational result for our Company. Historically, we have operated Tormin with a limited life of mine, and in the space of five months we have doubled our placer beach resources and secured this significant conventional resource that will become the pillar of our future mining operations. We have expedited development at the Western Strandline, with mining operations already commenced. It is anticipated that the Company will start processing material from the Western Strandline as early as September. This resource demonstrates the true potential of what we believe is a world class asset that our Company will be mining for decades to come”.

The Mineral Resource (Table 1) demonstrates the high-grade nature of the deposit, with over 40% of the total resource classified as Measured and Indicated.

S102 Mining Right area - 22.8 million tonnes at 20.9% THM located within expanded Mining Right area (22% of the total estimated resource) immediately available for mining.

The resource area comprises two areas totalling approximately 5.5km in total length and covering 75 hectares, is located adjacent to the existing plant and is approved for immediate mining operation as part of the recently granted S102 Mining Right. Almost 22% of the total estimated Mineral Reserve is located within the S102 Mining Right area ( 22.8 million tonnes at 20.9% THM ). The majority (85%) of the Mineral Resource that is within the S102 Mining Right is classified as Measured and Indicated (Table 2).

Mineral assemblage reported as in situ percentage of THM content

Development of the Western Strandline areas within the S102 Mining Right have commenced with a phased development program initially targeting the near surface, high grade strand horizons, with grades as high as 90% THM[2] comprising 7.54% Zircon[2,3] , 1.82% Rutile[2,3] , 34% Ilmenite[2,3] , 34% Garnet[2,3] intersected in the orebody, before processing the Red Aeolian and Orange Feldspathic Sands.

The high-grade THM mineralisation and Valuable Heavy Minerals (“VHM”)[4] assemblage observed in the ‘strand horizons’ from the resource drilling are reminiscent of similar grades and mineral assemblage encountered in the first years of mining the high-grade Tormin Beach areas. The reported VHM contains high constituent zircon, rutile, ilmenite, garnet assemblage as well as anatase and magnetite.[2 ]

Background

The Tormin operation is located approximately 370km north of Cape Town and approximately 30km from the township of Lutzville in the Republic of South Africa.

==> picture [452 x 309] intentionally omitted <==

Figure 3: Geographical location of the Company’s tenements in the Western Cape province of South Africa

The Inland Strands comprise multiple discrete palaeo strandlines running semi-parallel to the coastline and within the Company owned Geelwal Karoo Farm 262. Two palaeomarine strandlines have been identified, consisting of a Western Strandline (35-40m above mean sea level) and an Eastern Strandline (86m above mean sea level). Aeromagnetic data indicates that the Inland Strands run continuously along the coastline of the Company’s tenure portfolio.

In January 2020, the Company was granted Prospecting Right 10262PR covering an area of 1,741 hectares and some 12km in length. The initial Inland Strands area, which is adjacent to our existing mining operations, was subject to extensive resource definition drilling commencing in mid-February 2020 and targeting the geophysical aeromagnetic anomaly previously identified as a buried palaeo-strandline in 2014. Initial exploration results were released to the ASX on 7 April 2020, followed by additional results on 7 July 2020.

This first phase of the resource drilling campaign was completed, with a total of 6,917 metres drilled. The drilling program has concentrated on defining resources within the newly granted S102 Mining Right area which covers 5.5km of the currently identified 12km long Western Strandline horizon, as well as extensional drilling in the prospecting permit areas to the immediate north and south of the S102 Mining Right area.

Geology and geological interpretation

The western coastal plain of South Africa embraces a significant resource of detrital heavy minerals by world standards. The heavy mineral sand deposits occur in a current active beach environment (eg Tormin mine) as well as in older palaeo-beach raised strandlines found inland. The onshore mineral sands are marine palaeo-terraces “Inland Strands”, aeolian sands and fluvial sediments. These targets were formed during Miocene, Pliocene and Quaternary/Pleistocene coastal transgression (sea moving inland) and regression cycles.

The strandline is a concentration of high-grade VHM with overburden horizons above the strandline in the form of Aeolian facies (Orange Feldspathic Sand), erosion surface facies (dorbank, silcrete, calcrete) and Red Aeolian Sands deflation zones that have also been confirmed to be mineralised in places. The deposit hosts economic mineralisation in three main geological units of enriched high grade heavy mineral strandline deposits (1-12m thickness), bulk mineralisation in Orange Feldspathic Sand (1-44m thickness) and low grade in Red Aeolian Sand (0-11m thick-ness) as well as dorbank and gravel.

Drilling techniques and hole spacing

Exploration drilling included 6,733 metres of aircore drilling in 23 drill fence lines which are 250m apart on 20m spacings (247 holes), 11 infill drill fence lines on 25m spacing (64 holes) between the primary lines in the southern half of the Western Strandline, 6 drill fence lines which are 500m apart on 20m spacings (12 holes) on the north extension of the Western Strandline and two sonic holes (28m). Moreover, 16 holes (436m) from historical drilling were verified by recent drilling and included in the resource model.

Sampling and sub-sampling techniques

Each sample was riffle split into two pre-numbered calico bags of ~5kg each, one for primary assaying at the onsite mine laboratory and a duplicate for external QA/QC. The remaining sample was collected in a large plastic bag to be stored securely in a bag farm for reference. Primary samples of approximately 5kg were submitted directly to the Tormin mine laboratory to be analysed for slimes and heavy minerals.

Sample analysis method

A total of 7,369 samples were assayed. All samples were analysed by the onsite laboratory at the Tormin processing plant. The laboratory sample was dried, de-slimed (removal of - 45 micron fraction) and screened (+1mm oversize), then 200g of sample split to use for heavy liquid separation using Tetrabromoethane (“TBE”) with density range between 2.94 and 2.96g/ml to define THM content. The Tormin laboratory uses a heavy liquid separation (“HLS”) with TBE for heavy mineral analysis. It also uses Panalytical Aeris XRD machines (the Rietveld method after HLS) in an automated mode setup (THM program) and industrial laboratory XRF (Panalytical Epsilon 3 ED) as a grade verification check on the XRD zircon content. Additionally, 250 samples were sent to external laboratories in Pretoria and Johannesburg (XRD Analytical and Consulting, Mintek and UIS Analytical Services) for QA/QC purposes.

QA/QC has been undertaken by field and lab duplicates, Certified Reference Material (“CRM”) and blank samples and twin holes. In general, all QA/QC indicated good to moderately good performance.

Furthermore, quantitative mineralogical investigations by using scanning electron microscopy (“QEMSCAN”) on 18 metric and composite samples were undertaken by SGS and ALS laboratories for verification of the heavy mineral assemblage and VHM content as well as fraction size and trash minerals. In addition, optical microscopy grain counting was undertaken on 4 composite samples to study mineral assemblage composition and physical properties of valuable mineral particles.

Estimation Methodology and resource classification

The Mineral Resource estimation involved the use of drillhole and geology/topography to construct three-dimensional wireframes to define mineralised domains using Micromine software.

Domains were snapped to the nearest true intersection from sampling. Data was extrapolated between data points and approximately half of the drill spacing beyond. Ordinary kriging was used as the primary estimator for THM and VHM values. A block size of 50x12.5x1m reflects the geometry of the mineralised domains and drillhole spacing. Areas with drilling spaced at 125x25m were generally classified as Measured Resources and 250x20m was generally classified as Indicated Resources. Drilling up to 500x25m has been generally classified as Inferred Resources.

Where the slope of regression of the kriged estimate is greater than 0.85, and previous categories have been met, the final resource has been classified as Measured. Where blocks have slope between 0.7 and 0.85, even if other criteria have been met for higher classification, the resource was classified as Indicated. Where the slope is less than 0.7, even if other criteria have been met for higher classification, the resource was classified as Inferred.

Mining and metallurgical methods and parameters

Typical open-pit mining is practised with excavators and articulated dump trucks being utilised. The resource is considered as dry mining feed and mineralisation can be any depth or width. There is no stripping, except ~25cm topsoil, as mineralisation starts near the surface. The thickness and continuous nature of the mineralisation supports nonselective bulk mining methods. The Company believes there are no mining factors which affect the assumption that the deposit has reasonable prospects for economic mining.

The Company has undertaken initial metallurgical testwork. The metallurgical recovery is similar to other mineral sands operations and metallurgical parameters have been taken from the metallurgical tests to date. These tests support economic extraction of the deposit.

Future work

The Inland Strand deposit presents a significant mineral sands assets for the Company which offers material extension of mine life. The opportunity to develop and mine the Western Strandline is an important turning point for the Company in realising the value of the world-class Tormin Mineral Sands Operation. The Western Strandline represents the first conventional resource at Tormin and will become a cornerstone deposit, together with the Company’s existing Tormin Beaches and Northern Beaches mining areas. The recent JORC Resource of 2.5Mt @ 23.5% THM at the Northern Beaches has doubled the Company’s placer beach mining area and, by scheduling mining from the Western Strandline, the Company can optimise and manage the ongoing replenishment rate of these unique active placer beach mining deposits.

The Western Strandline Mineral Resource Estimate represents a twenty-fold increase in the Company’s Mineral Resources – Figure 11.

The Eastern Strandline of the Inland Strand deposit presents an additional exploration target, which has the potential to further expand the Company’s conventional mineral sands resources.

Bulk sampling from the Western Strandline is ongoing and development of the the first pit will commence in the coming few days. A new front end feed system will be constructed, including a crushing circuit, as well as additional classification, concentration and thickener circuits. These front end and additional upgrades will target increased total primary processing capacity from the current ~2.5Mtpa to up to 4Mtpa.[5]

Detailed testwork and engineering design work has already commenced on the planned front end upgrades, with the Company anticipating 4Mtpa[1] throughput capacity by 2022.

MRC targets delivery of Ore Reserve estimates in Q4 2020. The Company is continuing a 10,000m drilling program designed to infill the existing targeted resource areas and step out the resource along the extent of the known mineralised zones on the northern and southern extensions of the Western Strandline, as well as the Eastern Strandline, to complete fence line resource drilling as part of a strategy to unlock the full potential of the Prospecting Right by June quarter 2021.

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 1m samples from which 3kg was pulverised to
produce a 30g 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.

geological
structure
Whether the orientation of sampling achieves unbiased sampling of
possible structures and the extent to which this is known, considering
the deposit type.
If the relationship between the drilling orientation and the
orientation of key mineralised structures is considered to have
introduced a sampling bias, this should be assessed and reported if
material.
• Vertical drilling to intersect sub-horizontal strata.
• Orientation of the drillholes will not result in sampling bias.

• This Prospecting Right (Inland Strand) incorporates an area
approximately 12km in length covering 1,741 hectares of coastal
area adjacent to the existing beach mining operations on the
Company-owned farm Geelwal Karoo 262.
• Section 102 Mining Right (WC 30/5/1/2/2/10108 MR)
application encompassing the Northern Beaches and Inland
Strandline expansion project was approved by the Department
of Mineral Resources - South Africa on 30 June 2020.
Exploration
done by other
parties
Acknowledgment and appraisal of exploration by other parties. • The general area has been investigated and mined for heavy
mineral deposits as far back as the 1930s (Haughton, 1931).
Subsequent geological surveys and exploration programs
investigated the distribution, mineralogy and economic
potential of the heavy mineral sands along the coastline of
Geelwal Karoo (Toerien & Groeneveld 1957, Abele 1989, Swart
1990, Barnes 1998) and Trans Hex 1989-1991).
• De Beers drilled 9 fence lines across the property and bulk
sampled the area in the 1960s.
• During 1999, Trans Hex conducted additional onshore drilling of
strandlines and identified the inland raised beach deposits
containing heavy minerals. Trans Hex subsequently bulk
sampled the material by digging several trenches in 1999-2000.
• Geelwal Karoo Diamante conducted small diameter forum
drilling to a depth of 40m between 2000 and 2002, with a total
of 42 drillholes.
• Extensive work, including mining of the inshore strandlines
along the coast, was undertaken by Namakwa Diamond
Company in 2003-2005. This work also identified the presence
of the Inland Strand.
Geology Deposit type, geological setting and style of mineralisation. • The western coastal plain of South Africa contains a significant
resource of detrital heavy minerals by world standards.
• The heavy mineral sand deposits occur in a current active beach
environment (eg Tormin mine) as well as in older palaeo-beach
raised strandlines found inland (inland strandlines) eg Tronox
Namakwa Sands.
• Apart
from
the
mid-Jurassic,
Cretaceous
and
Tertiary
(Paleogene) sediments along the coast, numerous small
fossiliferous, marine and terrestrial deposits of Neogene age
outcrop along the coastal zone.
• The onshore mineral sands are marine palaeo-terraces “Inland
Strands”, aeolian sands and fluvial sediments. These targets were
formed during Miocene, Pliocene and Quaternary/Pleistocene
coastal transgression (sea move inland) and regression cycles.
• The lithological units of the Western Strandline can be described
as below:
a.
Aeolian sand – non mineralised
b.Red Aeolin sand – mineralised
c.
Silcrete Duricrust/ dorbank
d.Orange Feldspathic Sand – non mineralised
e.
Orange Feldspathic Sand – mineralised
f.
Dorbank – mineralised
g.Strandline – mineralised
h.
Base pebble beds – mineralised

• For purposes of estimation, the lithology has been grouped into
the following:
A: Red Aeolian sand
B: Silcrete Duricrust/dorbank
C: Orange Feldspathic Sand
D: Main Strandline Mineralisation (including the thin
mineralised dorbank)
E: Secondary perched strandline mineralisation
F: Gravel
Criteria Explanation Commentary
G: Schist basement
• The orebody hosts economic mineralisation in five geological
layers of enriched extremely high grade heavy mineral strandline
deposit, bulk mineralisation in Orange Feldspathic Sand and low
grade in red aeloian sand, silcrete/dorbank, and patchy
mineralisation in the basal gravel.
Drill hole
Information
A summary of all information material to the understanding of
the exploration results including a tabulation of the following
information for all Material drill holes:
Easting and northing of the drill hole collar
elevation or RL (Reduced Level – elevation above sea level in
metres) of the drill hole collar
dip and azimuth of the hole
down hole length and interception depth
hole length.
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.
• The minimum hole length is 6m, maximum 49m and average
depth of drilling is 21.8metres.
• East collar ranges – 220,486mE to 227,172mE.
• North collar ranges – 6,500,894mN to 6,510,977mN.
• Height collar ranges- 35.90m to 95.84m.
• Azimuth ranges/dip ranges – vertical drilling.
Data
aggregation
methods
In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (eg 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 relevent.
• No grade cutting of HM values were undertaken.
• No metal equivalents were used for reporting of 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 (eg ‘down hole
length, true width not known’).
• The strandline mineralisation is sub-horizontal in nature and the
air core drilling intercepts are vertical.
• Thickness of intercept reported is therefore true thickness of the
mineralisation.
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.
• Maps, sections and plan views are provided in the main body of
the report.
Balanced
reporting
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.
• Statistics of drillhole grades used during the Mineral Resource
Estimate are contained in the main body of the report.
• This report provides the total information available to date and
is considered to represent a balanced report.
Other
substantive
exploration
data
Other exploration data, if meaningful and material, should be
reported including (but not limited to): geological observations;
geophysical survey results; geochemical survey results; bulk
samples – size and method of treatment; metallurgical test
results; bulk density, groundwater, geotechnical and rock
characteristics;
potential
deleterious
or
contaminating
substances.
• Historical drill data is not reported as it is classified as historical
foreign estimates that are non-JORC compliant.
• Aeromagnetic geophysical data has been used for drilling target
delineations.
• Only 16 holes (436m) from historical drilling were verified and
included into the resource model.
Further work The nature and scale of planned further work (eg tests for lateral
extensions or depth extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions,
including the main geological interpretations and future drilling
areas, provided this information is not commercially sensitive.
• Further drilling is planned to produce a Measured/Indicated
resource over the North and South extensions of Western
Strandline and an Inferred/Indicated Resource over the Eastern
Strandline.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in Section 1, and where relevant in Section 2, also apply to this section)

Criteria JORC Code explanation Commentary
Database integrity Measures taken to ensure that data has not been corrupted
by, for example, transcription or keying errors, between its
initial collection and its use for Mineral Resource estimation
purposes.
Data validation procedures used.
• The data was plotted and plots where expected with no mis-plots
or extraneous data found. Maximum and minimum values and
average values were all within the norm. Duplicate values were
confirmed as such. The coordinates were confirmed as being
WGS84 UTM zone 34S.
• Data is stored in an offsite database hosted by Maxwell Geoservices.
Site visits Comment on any site visits undertaken by the Competent
Person and the outcome of those visits.
If no site visits have been undertaken indicate why this is
the case.
• The Competent Person is currently a full time employee of Mineral
Commodities Ltd.
• No site visits were undertaken for this resource estimate due to
COVID-19 travel ban, although the Competent Person did visit the
project previously and is familiar with the site and resource
conditions.
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.
• The deposit is a classic inland strandline mineral sands deposit with
no doubt as to its genesis.
• The grain size charactristics are interpreted to support an offshore
depositional setting, closer to the shoreline position.
• Samples were collected for resource estimation purposes.
• The geology/topography of the deposit has been used to constrain
the resource envelope. The data was partitioned into areas (subsets)
based on geology/topography. The base of the deposit is defined
by the underlying bedrock, the landward side by barren land and
sand dunes.
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 total deposit, inside MSR controlled Prospecting Rights, has a
strike length along the coastline of approximately 11,750m and an
average width from the dunes to within the surf zone of 150m. It is
developed from surface to a maximum depth of 49m and the
average resource thickness is approximately 21m. The deposit
occurs from the surface down.
Estimation and

of
extreme
grade
values,
domaining,
interpolation parameters and maximum distance of
extrapolation from data points. If a computer assisted
estimation method was chosen, include a description of

The availability of check estimates, previous estimates
and/or mine production records and whether the Mineral
Resource estimate takes appropriate account of such data.
The assumptions made regarding recovery of by-products.
Estimation of deleterious elements or other non-grade
variables of economic significance (eg sulphur for acid
mine drainage characterisation).
In the case of block model interpolation, the block size in
relation to the average sample spacing and the search
employed.
Any assumptions behind modelling of selective mining

Any assumptions about correlation between variables.
Description of how the geological interpretation was used
to control the resource estimates.
Discussion of basis for using or not using grade cutting or
capping.
The process of validation, the checking process used, the
comparison of model data to drill hole data, and use of
reconciliation data if available.
• Micromine software was used to domain and estimate each of the
valuable heavy minerals. Domains were snapped to the nearest true
intersection from sampling.
• Assays were all 1.0m, so no compositing was required.
• Outlier values were cut based on local analysis for each lithology
and each variable. There is a nugget effect of between 60 and 70%:
Top cut:
-
STRAND2 THM at 55%, garnet at 10%, ilmenite at 10%
-
Dorbank/silcrete THM at 30%
-
RAS THM at 15%, Garnet at 10%, Ilmenite at 5%, Zircon
at 1%, Rutile at 1%
• Data was extrapolated between data points and approximately half
of the drill spacing beyond. Data points are nominally 125 x 25m to
250 x 25m. There are generally between 2-15 drill holes per line.
• Ordinary kriging was used as the primary estimator. Each variable
was estimated separately, using variograms created for each
lithology. STRAND and STRAND2 lithology types. All lower grade
lithology units used an LGSAND variogram, constructed with data
from all lower grade lithology units.
• An anisotropic search was used, with the variable ratios of direction
of greatest continuity: Across the continuity: depth. (STRAND
1:0.4:0.04, STRAND2 2:0.6:0.06, LGSANDS 4:0.4:0.08) A maximum
search distance of 500m was used for both STRAND units, and 750m
for LGSAND units. Octant searching was used, with maximum points
per sector of between 5 and 12. Minimum points to estimate a block
were 5. These neighbourhood parameters were all confirmed using
cross validation.
• This is a resource estimate and mining parameters are not used
beyond normal global parameters of grades, dimensions, and
accessibility.
• The THM standard deviation in the block model is as follows:
-
12.1 with a coefficient of variation of 1.14
• These values are acceptable as they indicate the modelling
algorithm produces realistic values within the range of the dataset.
In addition, an in-depth validation process was used to test the
robustness of the modelled data, including visual checks, check
estimates (IDW and NN), swath plots and detailed statistical
comparisons.
Criteria JORC Code explanation Commentary
Moisture Whether the tonnages are estimated on a dry basis or with
natural moisture, and the method of determination of the
moisture content.
• The resource tonnages are estimated on a dry basis.
Cut-off
parameters
The basis of the adopted cut-off grade(s) or quality
parameters applied.
• Final report was based on a 2% THM cut off grade for blocks as this
is the current minimum grade where there is a reasonable
expectation for eventual extraction.
• 2% cut off grade was based on grade-tonnage curves with respect
to THM and VHM assemblage. Also taken into account was current
and anticipated plant performance, and other similarly sized
deposits in the region.
Mining factors or
assumptions
Assumptions made regarding possible mining methods,
minimum mining dimensions and internal (or, if applicable,
external) mining dilution. It is always necessary as part of
the process of determining reasonable prospects for
eventual economic extraction to consider potential mining
methods, but the assumptions made regarding mining
methods and parameters when estimating Mineral
Resources may not always be rigorous. Where this is the
case, this should be reported with an explanation of the
basis of the mining assumptions made.
• The resource is considered as dry mining feed and mineralisation
can be any depth or width. Dry mining techniques are preferred in
situations involving high grades.
• Mining would be through conventional open pit methods.
• There is no stripping except ~25cm top soil as mining starts at the
surface.
• The thickness and continuous nature of the mineralisation, supports
a non-selective bulk mining method.
• The Company believes there are no mining factors which affect the
assumption that the deposit has reasonable prospects for eventual
economic mining.
• For evaluation of resources within the S102 Mining Right area, the
Micromine block model was sub-blocked to 4x4x4m to aid selection
of blocks within this perimeter.
Metallurgical
factors or
assumptions
The basis for assumptions or predictions regarding
metallurgical amenability. It is always necessary as part of
the process of determining reasonable prospects for
eventual economic extraction to consider potential
metallurgical methods, but the assumptions regarding
metallurgical treatment processes and parameters made
when reporting Mineral Resources may not always be
rigorous. Where this is the case, this should be reported
with an explanation of the basis of the metallurgical
assumptions made.
• The metallurgical recovery is similar to other mineral sand
operations.
• Metallurgical parameters have been taken from the metallurgical
tests, and metallurgical testworks results support the recovery. The
VHM mineral assemblage, low slimes and oversize are fit for an
economic extraction. The level of garnet is slightly greater than at
other deposits.
• To date, any changes that MRC undertake have not been quantified
or assumed to change the product specifications.
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
greenfield 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.
• There are no environmental factors likely to affect the assumption
that the deposit has reasonable prospects for eventual economic
extraction.
• The local vegetation environment generally consists of strandveld
plant communities. Topsoil stripped from the mining operations will
be stockpiled for later use during rehabilitation.
• Tailings generated in the processing plant will be pumped back into
the open pits as part of the rehabilitation strategy. Any excess water
will be recovered and recycled to the process.
• There are no pollutants introduced with the tailings and the material
is inert, however further studies for tailing and slime waste
classification are ongoing.
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
evaluationprocess of the different materials.
• The bulk density is based on a calculation of the specific gravity of
the silica and heavy mineral content fractions of each sample. It is
therefore not fixed and fluctuates between 1.68 and 2.1 as per the
formula: SG=1.68+(0.0095 x THM).
• The use of a bulk density algorithm is a standard industry practice
for the estimation of mineral sands resource.
Classification The basis for the classification of the Mineral Resources into
varying confidence categories.
Whether appropriate account has been taken of all relevant
factors
(ie
relative
confidence
in
tonnage/grade
estimations, reliability of input data, confidence in
continuity of geology and metal values, quality, quantity
and distribution of the data).
Whether the result appropriately reflects the Competent
Person’s view of the deposit.
• The Mineral Resources have been classified as Measured, Indicated,
and Inferred Categories, in accordance with the 2012 Australasian
Code for Reporting of Mineral Resources and Ore Reserves (“JORC
Code (2012)”).
• A range of criteria has been considered in determining this
classification including:
o
Geological continuity
o
Drillhole spacing:
-
Areas with aircore drilling spaced at 125x25m have been
generally classified Measured
-
Areas with aircore drilling spaced at 250x20m have been
generally classified Indicated.
o
Slope of regression of the kriging estimate – this is a measure
of the robustness of the estimate:
Criteria JORC Code explanation Commentary
-
Where slope is greater than 0.85, and previous
categories have been met, the final resource has been
classified as Measured.
-
Where there is a cluster of blocks with slope between 0.7
and 0.85, even if other criteria have been met for higher
classification, the resource has been classified as
Indicated.
-
Where there is a cluster of blocks where slope is less than
0.7, even if other criteria have been met for higher
classification, the resource has been classified as
Inferred.
-
For GRAVEL and DORBANK lithologies, the thin nature of
the lithology has increased variability and decreased
confidence in tonnes reported, leading to lowering of
classification.
• The results of the validation of the block model show acceptable
correlation of the input data to the estimated grades.
• The author is confident that all relevant factors have been
considered and the results reflect his views.
Audits or reviews The results of any audits or reviews of Mineral Resource
estimates.
• The Mineral Resource has been reviewed internally as part of normal
validation processes by MRC.
• Wardell Armstrong International (“WAI”) conducted a review of the
Mineral Resource Estimate and no material issues were identified.
Mr Ché Osmond (CGeol) and Richard Ellis (CGeol) (WAI) undertook
an audit of the Mineral Resource estimate as an independent
technical review.
• This is considered to be a maiden Mineral Resource Estimate under
the guidelines of the JORC Code (2012) since this is the first resource
estimate completed in this project.
Discussion of
relative accuracy/
confidence
Where appropriate, a statement of the relative accuracy
and confidence level in the Mineral Resource estimate
using an approach or procedure deemed appropriate by the
Competent Person. For example, the application of
statistical or geostatistical procedures to quantify the
relative accuracy of the resource within stated confidence
limits, or, if such an approach is not deemed appropriate, a
qualitative discussion of the factors that could affect the
relative accuracy and confidence of the estimate.
The statement should specify whether it relates to global or
local estimates, and, if local, state the relevant tonnages,
which should be relevant to technical and economic
evaluation. Documentation should include assumptions
made and the procedures used.
These statements of relative accuracy and confidence of the
estimate should be compared with production data, where
available.
• An in-depth geostatistical study has been completed on this
resource, which has allowed for robust estimation and high levels of
confidence in the resource.
