Cleveland Tailings Project - Positive Metallurgical Test Results

Highlights

  • Metallurgical test work supports the previous testing and proposed flow sheet designs for the Cleveland Tailings Project

  • The rehabilitation and retreatment of the Cleveland Tailings Mineral Resource[1] will produce a concentrate from gravity and flotation processing, of between 50-55% tin at a recovery of 48-50%

  • Submission of the Development Proposal and Environmental Management Plan is scheduled for early 2015

  • Lodgment of the Mining Lease Application is planned for early 2015, with a view to beginning production in 2016

Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to report the positive results of a metallurgical test program, which required the testing of composite samples from the two Cleveland tailings dams (TD1 and TD2). The work was performed at the ALS laboratory in Burnie, Tasmania, under the supervision of Mike Gunn, an experienced metallurgist specialising in the recovery of tin.

After mass balancing of the metal content, the two tailings deposits indicated very similar overall performance. The mass balance shown in Table 1 (below) is a blend of the results achieved at each process stage for each tailings dam.

Table 1: Preliminary Results for Saleable Concentrate Grade and Recovery

Tonnes Per

Grade
Gravity Tin Product(Dressed) 0.22 42.2% 29.1%
Flotation Tin Product(Dressed) 0.18 36.0% 20.5%
Total Tin Product(Combined Concentrate after Leaching) 0.30 52.6% 49.6%
Total Tin Tail Reject 104.62 0.15% 50.4%

The results support the Company’s plans to submit a Development Proposal and Environmental Management Plan in early 2015, in conjunction with the lodgement of a Mining Lease Application, with a view to beginning production in 2016.

1 The information is extracted from the report entitled “Resource Upgrade – Cleveland Tailings Resource” created on 17 June 2014, which is an update on previously reported work entitled “Cleveland JORC Resources Significantly Expanded” which was released on the 5 March 2014. Both reports are available to view at www.elementos.com. The company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement and, in the case of estimates of Mineral Resources or Ore Reserves, that all material assumptions and technical parameters underpinning the estimates in the relevant market announcement continue to apply and have not materially changed. The company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original market announcement.

Background

111 samples (~479kg) were taken as part of a sampling program at the Cleveland tailings dams. Of these samples, 33 from TD1 and 52 from TD2 were selected and composited into a main feed sample for batch gravity testing. The rejected samples were either clay cap material or remnant Hellyer tailings from a past plant trial. The composite sizing and assays were consistent with the weighted average of sample interval sizing and assays. They were also comparable with the estimate of the average tailings grade calculated from historical production data.

The test work was based largely on the flow sheet used by Cleveland Tin Mining Company N.L. in pilot tests in 1984. This testing was designed to separately define the performance of each of the process steps for TD1 and TD2. No regrinding of the gravity middlings streams and no dressing of concentrates were undertaken. Flotation testing was conducted as a batch test with no retreatment of cleaner tailings.

Note the arrangement of the process stages in the mass balance is distinctly different from the sequence of stages in the test work. The mass balance developed from these test results allows for the losses incurred by upgrading of concentrates.

Other Material Results

Other material results from the sample analysis and testing include:

  • The data from the individual test stages was sufficiently consistent and reliable to enable a preliminary overall mass balance to be developed;

  • All pre-dressed concentrates are carrying around 50% by mass of siderite, an iron carbonate (FeCO3), which can be leached out with acid to achieve higher product grade;

  • Sulphide removal by flotation and Low Intensity Magnetic Separation (LIMS) and desliming at 6 microns were all carried out with an expected and acceptable loss of tin;

  • Siderite removal from flotation feed was tested in isolation using Wet High Intensity Magnetic Separation (WHIMS) with an expected and acceptable loss of tin;

  • As expected, samples were sticky and handling was difficult. However, these material handling characteristics can be managed through a variety of mining methods;

  • De-agglomeration using a high shear attritioner was effective;

  • Individual sample intervals showed a very broad range of particle sizing, emphasising the requirement for homogenisation of the plant feed; and

  • The tailings reject showed potential to generate acid over time in the tailing storage facility. The Company plans to provide adequate controls through best practice engineering in its tailings dam design.

Next Steps

A second phase of testing will be required to finalise plant design and its performance criteria as part of a Definitive Feasibility Study, scheduled to commence in the first half of 2015. This will include collecting a bulk sample from both tailings dams and processing the material through a pilot plant (locked cycle test) to confirm plant specifications. The work will include the sub-sampling of material for testing of a Falcon Ultra-Fine Concentrator and quantification of concentrate penalty elements.

Appendix Three – Supporting Data Tables

Section 1: Sampling Techniques and Data

Criteria JORC Code Explanation Commentary
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.
21 ‘Wacker’ holes provided 111 samples. Of the
111 samples, 33 from TD1 and 52 from TD2 were
selected and composited into the main feed
sample for batch gravity testing. The rejected
samples were either clay cap material or historic
Hellyer tailings.
The composite sample sizing and assay were
consistent with the weighted average of sample
interval sizings and assays. They were also
comparable with the estimate of the average
tailings grade calculated from historical production
data.
No duplicate samples were collected and no
standards were incorporated in the sample batch.
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.).
‘Wacker’ sampling was used. This technique
utilises a continuous sample recovery barrel,
enabling a full column of sample of tailings
material to be recovered.
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 ‘Wacker’ sampling method provides a full
column of sample to be recovered. However, not
all samples covered the full depth of the tailings.
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.
All samples acquired were logged for material
type, with full paper and electronic logs made
available in the Company database. Photos were
taken of all samples before they were stored in a
freezer pending the above-mentioned metallurgical
testing.

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.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
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,
including for instance results for field
duplicate/second-half sampling.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
The samples received were weighed and sub
sampled to provide material for sample
characterisation, which entailed assays and
particle sizing at -38um.
Future work will need to assess in-situ bulk density
and moisture content, as the moisture of 19% was
derived from a composite of stored drill intervals,
and cannot be relied upon.
The comparison of sizing indicates that the
individual analysis of drilled intervals is consistent
with the composite sizing. 33 TD1 and 52 TD2
samples selected from the original 111 sample
intervals and were composited into a main feed
sample for batch gravity testwork.
The rejected samples were either clay cap
material or Hellyer tailings.

factors applied and their derivation, etc.
Nature of quality control procedures adopted (e.g.
standards, blanks, duplicates, external laboratory
checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have
been established.
The laboratory analysis technique utilises the
entire sample. The laboratory assay procedure is
considered appropriate for samples of this type.
No additional quality control measured beyond the
standard laboratory "checks and balances"
implemented by the laboratory as part of their
normal assaying procedure were conducted.
Verification
of sampling
and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
The use of twinned holes.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Discuss any adjustment to assay data.
Independent consultants Pitt & Sherry supervised
the ‘Wacker’ sampling. No twinning was deemed
necessary due to the compositing of the samples
for bulk determination.
All data collection, verification and protocols were
set under the guidance of independent consultants
Pitt & Sherry.
Mass balancing was used to interpret the results.
This is a blend of the deportments achieved at
each process stage for each tailings dam. The
arrangement of the process stages in the mass
balance is distinctly different from the sequence of
the process stages in the testwork. The mass
balance developed from these test results allows
for the losses incurred by upgrading of
concentrates.
Location of
data points
Accuracy and quality of surveys used to locate
drillholes (collar and down-hole surveys),
trenches, mine workings and other locations used
in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
A hand held GPS was used to record sample
locations (+/- 5m accuracy).
The samples were plotted using the Map Grid of
Australia (MGA) based upon the Geodetic Datum
of Australia 1994 (GDA94).

Data
spacing and
distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is
sufficient to establish the degree of geological
and grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation
procedure(s) and classifications applied.
Whether sample compositing has been applied.
The spacing of sample sites was determined to
best represent a consistent sampling of each of
the tailings dams whilst allowing for safe and
effective access.
The composite sizing and assay were consistent
with the weighted average of sample interval
sizing and assays. They were also comparable
with the estimate of the average tailings grade
calculated from historical production data.
Orientation
of data in
relation to
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.
The samples were taken vertically, which is more
or less perpendicular to the general stratification in
the tailings dam.
Sample
security
The measures taken to ensure sample security. Samples were collected in the field and stored in a
secure lockable location until dispatched to the
laboratory via company personnel and vehicle
where the laboratory assumed custody of the
samples.
Audits or
reviews
The results of any audits or reviews of sampling
techniques and data.
No audits or reviews have been conducted at this
stage.

Section 2: Reporting of Exploration Results

Criteria JORC Code Explanation Commentary
Mineral
tenement
and land
tenure status
Type, reference name/number, location and
ownership including agreements or material
issues with third parties such as joint ventures,
partnerships, overriding royalties, native title
interests, historical sites, wilderness or national
park and environmental settings.
The security of the tenure held at the time of
reporting along with any known impediments to
obtaining a licence to operate in the area.
Exploration Licence EL7/2005 covers the
Cleveland mine and Mineral Resource and is 100%
owned by Elementos Ltd, through its wholly owned
subsidiary Rockwell Minerals (Tasmania) Pty Ltd.
Exploration
done by
other parties
Acknowledgment and appraisal of exploration
by other parties
Exploration and mining has been conducted in the
area since 1898. Recent exploration and mining
activities include, exploration by Aberfoyle Tin
Development Partnership (1961-65), exploration
and mining by Cleveland Tin NL and Aberfoyle
Limited (1968-86), exploration by Lynch Mining Pty
Ltd (2007) and exploration by Rockwell Minerals
Limited (2013).
Geology Deposit type, geological setting and style of
mineralisation
Historical mining at Cleveland produced a tailings
legacy that the company proposes to reprocess as
part of its strategy for the Province. The tailings are
stored above ground on-site in two tailings dams
(TD1 and TD2). The tailings contain a substantial
quantity of recoverable tin and copper due in part
to
operational
inefficiencies
and
technical
limitations of tin processing whilst the mine was in
operation.
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.
No drilling was conducted to produce the samples
for the bulk composite.
Samples were extracted by ‘wacker’ method which
uses a hand-held mechanised push tube process
to extract material from the tailings dams.

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.
Samples were composited into the main feed
sample for batch gravity testing. The rejected
samples were either clay cap material or historic
Hellyer tailings.
The composite sample sizing and assay were
consistent with the weighted average of sample
interval sizing and assays.
Mass balancing was used to interpret the results.
This is a blend of the tin deportments achieved at
each process stage for each tailings dam. The
mass balance developed from these test results
allows for the losses incurred by upgrading of
concentrates.
Relationship
between
mineralisatio
n 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 samples were composited for bulk assessment
purposes and do not represent intersections.
The results were for material characterisation and
do not imply any lengths, volumes or quantitates of
mineralisation.
Diagrams See figures in this announcement.
Balanced
reporting
All sampling results have been reported.
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.
The metallurgical amenability of the tin copper
mineralisation was established by mining and
processing operations from 1968 to 1986.
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.
No future drilling is envisaged at this time.
A bulk sample is planned as part of a Definitive
Feasibility Study in 2015, but a submission for
approval of to take a bulk sample has not yet been
submitted.
