BASE RESOURCES LIMITED
Preliminary Exploration Results
HIGHLIGHTS
- Additional mineralisation discovered that extends the footprint
of the Kwale South Dune Deposit to the south by 950m and east by up
to a further 500m.
- Discovery of a new dunal mineral deposit at Mafisini, a
continuation of the Kwale South Dune Deposit mineralisation, with
recorded intercepts over a contiguous 1240m of strike and up to
480m in width.
- Discovery of new dunal mineralisation and marine sediments in
the NE Sector, adjacent to the Kwale Central Dune.
Base Resources Limited (ASX & AIM: BSE) ("Base
Resources" or the “Company”) is pleased to provide
preliminary exploration results of the extensional and infill
drilling program completed to date for its Kwale Mineral Sands
Operations (“Kwale Operations”) in Kenya, East Africa. Strong drilling
results clearly demonstrate the potential to grow resources and
mine life to the north and south of existing project reserves.
As previously announced, the Company commenced an aircore
drilling program in the December 2016
quarter, within its Special Prospecting License 173 (“SPL
173”). The drill program aims to provide mine life
extension to the Kwale Operations by exploring two previously
identified prospective areas adjoining or near the existing Kwale
Operation ore bodies: the south-west sector (“SW Sector”)
and north east sector (“NE Sector”) (refer Figure 1).
An airborne geophysics program, conducted in 2015, covering the
south coast region of Kenya from
Mombasa to the Tanzanian border, identified a series of exploration
targets that were subsequently confirmed through ground
reconnaissance. A summary of drilling completed to the
23rd February 2017 is included in
Table 1 and shown in Figure 1.
“Figures” (graphics) referenced in this release have been
omitted. A full PDF version of this release, including all
Figures, is available from the Company’s website:

SW Sector – Kwale South Dune Deposit
extension & Mafisini Deposit
Exploration drilling in the SW Sector at Kwale has substantially
increased the dimensions of the South Dune Deposit and intersected
a new dunal heavy mineral sand deposit at Mafisini (“Mafisini
Deposit”) (refer Figure 2). The Kwale South Dune Deposit
has been extended a further 950m to the south at an average of 700m
across strike. The Mafisini Deposit is a continuation of the
Kwale South Dune mineralisation, separated from it by a narrow
alluvial lowland. Mafisini records mineralised intervals over
a contiguous 1240m of strike and up to 480m in width.
Visual inspection of the Kwale South Dune Deposit extension and
Mafisini Deposit mineralisation indicates a similar composition and
high-value mineralogy as that reported for the Kwale Operations
Mineral Resources (134.6Mt at 4.2% heavy mineral (“HM”), 26%
slimes, 2% oversize and a HM assemblage of 59% ilmenite, 13% rutile
and 6% zircon - refer ASX release 11th
October 20161). Detailed mineralogy and
resource estimation are expected to be completed in the September
quarter.
[Note 1: Refer to the “2016
Mineral Resources and Ore Reserves Update for Kwale” released on
11 October 2016, which is available
at http://www.baseresources.com.au/investor-centre/asx-releases/.
Base Resources 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 Mineral Resources
and Ore Reserves, that all material assumptions and technical
parameters underpinning the estimates in the original market
announcement continue to apply and have not materially
changed.]
Representative cross sections of the discoveries are included in
Figures 3 and 4 (excluding infill holes) and significant drill
intercepts are included in Appendix 2.
NE Sector
Exploration drilling has commenced in the NE Sector, where the
marine escarpment falls away to the coastal plain (Figure 5).
Initial results indicate significant additional, high-value,
mineralised dune accumulations occur on the escarpment adjacent to
the Kwale Central Dune Deposit (Figure 6).
Extensive community engagement has continued in the NE Sector to
obtain informed consent and access to the target drill sites
located in this area. However, increasing political
positioning ahead of Kenya’s general elections, currently scheduled
for August 2017, has produced
community tensions not conducive to exploration and so the Company
has decided to postpone further drilling until sentiment improves,
likely to be after the elections.
Marine sediments have been intersected at the base of the
escarpment in the NE Sector at around 20m above sea level (Figure
6). Mineralisation (incl. 1.5m @ 10.75% HM from 25.5m in
ke001) has been discovered in what appears to be a beach placer
setting. The extent of the new discovery remains to be
determined by further drilling and is open in all axes.
Return of complete assays from the drilling in the NE Sector is
awaited. Mineralised intercepts received to-date are included
in Appendix 2. Intensive geological interpretation of down-hole
results and further community engagement will be conducted prior to
further drilling in this region.
Kwale South Dune Deposit – edge
definition and infill drilling
Base Resources has completed a program of edge-definition
drilling along the eastern margin of the Kwale South Dune Deposit
(currently 88.5Mt @ 3.5% HM - refer ASX/AIM Release 11th October 20162). Results
suggest that the deposit may be extended by as much as 500m east of
its current location.
[Note 2: Refer to note
1.]
Additionally, an infill drill program has been completed to
bring the Kwale South Dune Deposit to a (nominally) 100m x 100m
drill pattern, and provide the basis for upgrading the geological
confidence of Inferred and part of the Indicated Resource areas of
the deposit to a Measured status. Any Inferred Resources
achieving an Indicated or Measured Resource status will in turn be
eligible for inclusion within the Kwale South Dune Ore
Reserves. Appreciable Ore Reserve increases are anticipated
from this work.
Detailed mineralogy and resource estimation are expected to be
completed in the September quarter.

APPENDIX 1: Table 1, JORC Code
2012
Section 1: Sampling Techniques and
Data
Criteria |
Explanation |
Comment |
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. |
Sample sub-splits are
collected at a standard 1.5m down-hole interval, using an on-board
rotary splitter mounted beneath the drill rig cyclone. Sample gates
are set at 25% of the splitter cycle, which delivers about 2kg of
sample, dependant on ground conditions. |
|
Include reference to
measures taken to ensure sample representivity and the appropriate
calibration of any measurement tools or systems used. |
Appropriate drilling
equipment and driller training is a prerequisite of the drilling
contract. A rotary splitter (regularly cleaned) is used for
splitting drill samples in the field and a robust QA/QC and audit
system is established.
Consistency in split sample weights is monitored via intermittent
testing in the field with spring scales and through recording of
air-dried sample weights at sample preparation. Weights are
generally between two and three kilograms and this is considered
representative for the detrital material being sampled.
|
|
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. |
RCAC drilling is used
to obtain a 1.5m samples from which approximately 1.2-2.5 kg is
collected using a rotary splitter beneath a cyclone. The sample is
then dried, de-slimed (material less than 45 µm removed) and then
oversize (material +1mm) is removed.
Approximately 100g of the resultant sample is then subjected to a
heavy mineral (HM) float/sink technique using Lithium
Heteropolytungstates (LST:SG=2.85g/cm3).
The resulting HM concentrate is then dried and weighed. |
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.). |
All samples are
generated by RCAC drilling utilising ~71 mm diameter (NQ) air-core
drill tooling. Drill holes are oriented vertically by eye.
|
Drill sample
recovery |
Method of recording
and assessing core and chip sample recoveries and results
assessed. |
Base Resources log
sample quality at the rig as either good or poor, with ‘good‘
meaning not contaminated and of an appropriate sample size
(recovery), and ‘poor’ meaning contaminated or grossly
over/undersized.
Ground conditions vary and as such, the use of water injection is
also logged in the sample quality field for every sample interval
(dry, moist, injected or wet).
No sample loss has been recorded. The configuration of drilling and
nature of sediments encountered results in negligible loss. |
|
Measures taken to maximise
sample recovery and ensure representative nature of the
samples. |
Drill penetration is
halted at the end of each sample interval to allow time for the
sample to return to surface and be collected. Drilling
proceeds once sample delivery ceases.
Sampling on the drill rig is observed to ensure that rotary
splitter remains clean. Water flush and manual cleaning of
the cyclone occurs at regular intervals to ensure contamination is
minimised. |
|
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. |
No relationship is believed to exist
between grade and sample recovery. The high percentage of silt and
low hydraulic inflow of groundwater results in a sample size that
is well within the expected size range. |
Logging |
Whether core and
chip samples have been geologically and geotechnically logged to a
level of detail to support appropriate Mineral Resources
estimation, mining studies and metallurgical studies. |
Base Resources collects
detailed qualitative logging of geological characteristics to allow
a comprehensive geological interpretation to be carried out.
Logging of HM sinks with a microscope also is used to inform the
geological interpretation. |
|
Whether logging is
qualitative or quantitative in nature. Core (or costean, channel,
etc.) photography. |
Logging of RCAC samples record
sample quality, washability, colour, lithology, grainsize, sorting,
induration type, hardness, estimated rock and estimated HM. |
|
The total length and
percentage of the relevant intersections logged. |
All drill holes are logged in full
and all samples with observed HM (and designated for assay) are
assayed. |
Sub-sampling
techniques and sample preparation |
If core, whether cut or
sawn and whether quarter, half or all core taken. |
All samples are unconsolidated and
comprise sand, silt, clay and rock fragments. |
|
If non-core, whether
riffled, tube sampled, rotary split, etc. and whether sampled wet
or dry. |
Base Resources rotary
split the samples on the drill rig as they are delivered from
drilling (wet, moist, injected or dry). Low groundwater pressure
and rotary splitting delivers a representative sample for logging.
The 25% split delivers approximately 2 kg of sample for
analysis.
Drill samples are dried then riffle split to produce a ~300g sample
for de-sliming and oversize removal. The resultant sand
fraction is then delivered to the laboratory for heavy liquid (LST)
separation. |
Sub-sampling
techniques and sample preparation, cont’d. |
For all sample types, the
nature, quality and appropriateness of the sample preparation
technique. |
Base Resources use a
standard flow sheet and detailed QA/QC is undertaken.
The sample, designated in the field for analysis, is air dried,
weighed and pulverized for riffle splitting. Two splits are
generated of approximately 350 – 500g each and the remainder of the
original sample is recorded and stored.
One split is oven dried to establish moisture content of the
air-dried sample. The second split is soaked in water and a
de-flocculating agent prior to attritioning and de-sliming with a
45µm screen.
The sample is then dried and weighed to determine material lost
(Slimes weight) during screening. The dried sample is
then screened at 1mm and the oversize is weighed. The
remaining dry sand fraction is then delivered to the on-site
analysis laboratory (SGS) for heavy liquid separation by TBE. |
|
Quality control procedures
adopted for all sub- sampling stages to maximise representivity of
samples. |
To maintain QA/QC, a
duplicate and standard assaying procedure has been implemented.
A duplicate sample is collected at the rig at every 20th sample by
the application of a second calico bag to the second, 25% split
chute on the splitter. Both samples are subjected to the
complete sample preparation and assaying process.
In the sample preparation area, at a rate of 1:40, duplicates of
the moisture content sample and screened sample are taken. These
are subjected to moisture content (split 1) and de-sliming/oversize
(split 2) determinations to ensure samples do not exhibit bias.
A certified standard sample is submitted in the field and a second
certified standard sample is submitted to the laboratory after the
sample preparation stage, each at a rate of 1:40, to monitor
analysis accuracy. |
Sub-sampling
techniques and sample preparation, cont’d. |
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. |
Analysis of sample
duplicates is undertaken by standard geostatistical methodologies
(QQ Plots) to test for bias and to ensure that sample splitting is
representative.
Standards determine assay accuracy performance, monitored on
control charts, where failure (beyond 3SD from the mean) triggers
re-assay of the affected batch. |
|
Whether sample
sizes are appropriate to the grain size of the
material being sampled. |
Given that the grain size of the
material being sampled is sand and approximately 70 to 300 µm, an
approximate sample size of 2 kg is more than adequate. |
|
Quality of assay data and
laboratory tests |
The nature, quality and
appropriateness of the assaying and laboratory procedures used and
whether the technique is considered partial or total. |
Laboratory analysis of
drill samples is conducted by the Kwale, onsite contract
laboratory, managed by SGS.
Analysis is conducted according to a flow sheet that represents
standard, best practice for the assessment of HM and is supported
by robust QA/QC procedures.
Sand samples delivered to SGS are rotary split to generate a ~100g
sample for LST separation. Excess sand fraction is labelled
and stored.
The LST sink progresses till it clears and the sink is removed,
washed in acetone, oven dried and weighed.
LST is cleaned and density checked on a daily basis. |
|
|
For geophysical tools,
spectrometers, handheld XRF instruments, etc., the parameters used
in determining the analysis including instrument make and model,
reading times, calibrations factors applied and their derivation,
etc. |
None used. |
Quality of
assay data and laboratory tests, cont’d. |
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. |
Field duplicates, sample preparation
duplicates and laboratory replicates are submitted for precision
and bias analysis. Standard samples are submitted to
determine analysis accuracy. |
Verification
of sampling and assaying |
The verification of
significant intersections by either independent or alternative
company personnel. |
Verification of
significant intercepts is conducted by the Base Resources
Exploration Superintendent. The deposit type and consistency
of mineralization leaves little room for unexplained variance.
Data entry errors were identified by the Exploration Superintendent
and these were corrected (where obvious) or re-assay was
completed. |
|
The use of twinned
holes. |
Twinned holes account for 4 – 5% of
holes drilled at Mafisini Deposit and Kwale South Dune Deposit
extensions. These will be used to determine short-range
geological and assay field variability for resource modelling
purposes. |
|
Documentation of
primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols. |
Data collected by Base Resources is
entered digitally in the field using ruggedized computer with
Maxwell Geoscience logging software. Data is downloaded daily
to the site server. Migration to a Datashed Database is
planned. |
|
Discuss any
adjustment to assay data. |
No adjustments were made to
data. |
Location
of data points |
Accuracy and quality of
surveys used to locate drill holes (collar and down-hole surveys),
trenches, mine workings and other locations used in Mineral
Resources estimation. |
Base Resources use a real time
kinematic global positioning system (‘RTK GPS’) to pick up drill
collar locations. Survey is completed by Company surveyors.
Original drill set-out is completed by hand-held GPS. |
|
Specification of the grid
system used. |
The grid system used is the Arc1960
(Zone 37 South). The drill pattern is based on a local grid
rotation to ensure drill lines are oriented orthogonal to the trend
of mineralization. The Kwale South Dune Deposit Local Grid is used
at Mafisini Deposit and Kwale South Dune Deposit extensions. |
Location
of data points, cont’d. |
Quality and adequacy of
topographic control. |
A LiDAR survey was conducted in
November 2013 at an accuracy of 0.015m and is available for
topography modelling in the NE Sector and at Mafisini Deposit and
Kwale South Dune Deposit extension areas. |
Data spacing
and distribution |
Data spacing for reporting
of Exploration Results. |
The data spacing drilling is
nominally 100m North, 50m East, and 1.5m down hole for exploration
results. Variations from this spacing result from
line-clearing difficulties prior to drilling and drill site survey
and are not a result of access or traversing issue. |
|
Whether the
data spacing and distribution is sufficient to establish
the degree of geological and grade continuity appropriate for the
Mineral Resources and Ore Reserves estimation procedure(s) and
classifications applied. |
Based on the experience of the
competent person, the data spacing and distribution is considered
adequate for the definition of mineralisation and adequate for
proposed mineral resource estimation. |
|
Whether sample
compositing has been applied. |
No sample compositing or
de-compositing has been applied. |
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. |
Sample orientation is vertical and
approximately perpendicular to the dip and strike of the
mineralization, which results in true thickness estimates. Drilling
and sampling is carried out on a regular rectangular grid that is
broadly aligned and in a ratio consistent with the anisotropy of
the mineralisation. |
|
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. |
There is no apparent bias arising
from the orientation of the drill holes with respect to the strike
and dip of the deposit. |
Sample
security |
The measures taken to
ensure sample security. |
All samples are numbered, with
sample splits, residues and HM sinks registered and stored at Kwale
site in a restricted access storage shed. |
Audits or
reviews |
The results of any audits
or reviews of sampling techniques and data. |
Richard Stockwell (Hornet Drilling
and Geological Services Pty Ltd) conducted two site visits to
review drilling and sample preparation procedures. Minor
recommended changes were made on each occasion. |

Section 2: Reporting of Exploration
Results
Criteria |
Explanation |
Comment |
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 exploration results
are coincident with the granted Special Mining Lease No.23 and
Special Prospecting License No. 173.
Mining on SML23 is subject to an ad valorem royalty of 2%, payable
to the previous owners, and currently a 2.5% royalty, payable to
the Kenyan government. |
|
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. |
There are no known impediments to
the security of tenure over the area containing the reported
exploration results. |
Exploration done by
other parties |
Acknowledgment and
appraisal of exploration by other
parties. |
The previous owners of the project
(Tiomin Kenya Ltd) undertook exploration drilling over the Kwale
Project (incl. South Dune area). Tiomin data is included in
the Kwale HM Resource estimations. |
Geology |
Deposit type, geological
setting and style of mineralisation. |
Exploration results are indicative
of aeolian (dunal) detrital heavy mineral sand deposits. |
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:
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. |
Intercepts are listed
in the body of the release.
There are no further drill hole results that are considered
material to the understanding of the exploration results.
Identification of the wide and thick zone of mineralisation is made
via multiple intersections of drill holes and to list them all
would not give the reader any further clarification of the
distribution of mineralisation throughout the deposit. |
Data aggregation
methods |
In reporting Exploration
Results, weighting averaging techniques, maximum and/or minimum
grade truncations (e.g. cutting of high grades) and cut-off grades
are usually Material and should be stated. |
Exploration results are
reported at a minimum 2% HM bottom cut-off over a minimum depth
interval of 3m. This has been applied to ensure brevity in
the release.
Kwale HM Resources are reported at a 1% HM bottom cut-off. |
|
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. |
Does not apply |
Data aggregation methods,
cont’d. |
The assumptions used for
any reporting of metal equivalent values should be clearly
stated. |
No metal equivalents were used for
reporting of exploration results. |
Relationship between
mineralisation widths and intercept lengths |
These relationships are
particularly important in the reporting of Exploration
Results. |
All drill holes are vertical and
perpendicular to the dip and strike of mineralisation and therefore
all interceptions are approximately true thickness. |
|
If the geometry of the
mineralisation with respect to the drill hole angle is known, its
nature should be reported. |
Dune deposits typically approximate
a horizontal accumulation over a variable basement
topography. |
|
If it is not known and
only the down hole lengths are reported, there should be a clear
statement to this effect (e.g. ‘down hole length, true width not
known’). |
|
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. |
Refer to main body of release. |
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. |
Reporting of results is restricted
to type sections and more comprehensive tabulated results at a 2%
HM bottom cut and a minimum 3m interval. |
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. |
Whilst mineralogical
investigation is still awaited, a similar high-value assemblage, as
recorded for the Kwale Mineral Resource (~19% Rutile + Zircon), has
been observed on the dunal deposits during preliminary microscope
investigation of exploration samples.
Some lateritic fragments have been observed in a narrow and
discontinuous zone (~3-6m in thickness) near the base of the South
Dune southern extension and Mafisini Deposits that will have
resulted in elevated HM results returning from heavy mineral
analysis. This zone will be constrained during geological
interpretation and subsequent works. |
Further work |
The nature and scale of
planned further work (e.g. tests for lateral extensions or depth
extensions or large-scale step-out drilling). |
Geological
interpretation is ongoing at the Kwale South Dune Deposit
extension, Mafisini Deposit and in the NE Sector. Once
complete, mineralogical analysis will ensue and results will feed
into updated and new resource estimates. Resource estimation
of the Kwale South Dune and Mafisini is anticipated the September
quarter.
Further community engagement is required to continue drilling in
the NE Sector, which is not expect to take place until after
Kenya’s general elections, currently scheduled for August
2017. |
