Heron Resources Limited (ASX:HRR TSX:HER, “Heron” or the
“Company”) is pleased to provide further assay and DHEM
results from the drilling program recently completed at its
wholly-owned Woodlawn Project, located 250km south-west of Sydney,
New South Wales, Australia.
- Significant high grade assays received from B Lens
step-out drilling:
- 7m @ 14.3% ZnEq[1]
from 575m (6.1% Zn, 1.4% Cu, 3.2% Pb, 0.18g/t Au, 35g/t Ag)
WNDD0108
- 5m @ 19.5% ZnEq from 552m (7.7% Zn, 1.3% Cu, 3.9% Pb,
1.8g/t Au, 100g/t Ag) WNDD0108
- Down hole electromagnetic (DHEM) survey on WNDD0108
outlines the potential for a significant extension to the B Lens
position to the north-west
- An Exploration Target[2]
in this B Lens extensional area is in the order of 0.6Mt to
1.1Mt at grades between 7.0% and 14% ZnEq
- DHEM at the shallow G2 position has identified a number
of conductors that warrant drill testing and which have the
potential to materially add to the early mining
inventory
Commenting on these latest results, Heron Resources Managing
Director and CEO, Mr Wayne Taylor, said:
“These latest results clearly confirm the extension of the B
Lens system at Woodlawn with new high grade mineralisation to its
north west that has the potential to substantially add to the
mining inventory. Underground access to this new zone would utilise
the same development infrastructure as the main B Lens, enhancing
the economics of Woodlawn mine. Importantly, this area remains open
for further resource extensions.”
B Lens North Drilling
As previously reported, two holes were drilled to test the
concept of an extension to the B Lens mineralisation to the
north-west. Assay results from the second B Lens
extension hole, WNDD0108, have now been received:
- 11m @ 8.43% ZnEq from 569m (3.4% Zn, 0.94% Cu, 1.5% Pb,
0.12g/t Au, 18g/t Ag)
- Including 5.7m @ 14.3% ZnEq from 575m (6.1% Zn, 1.4%
Cu, 3.2% Pb, 0.18g/t Au, 35g/t Ag)
- 5m @ 19.5% ZnEq from 552m (7.7% Zn, 1.3% Cu, 3.9% Pb,
1.8g/t Au, 100g/t Ag)
The intercept at 569m comes from the B Lens horizon and consists
of a copper stringer zone combined with typical polymetallic
high-grade massive sulphides. It includes a higher grade zone
as described above from 575m to 580.6m. The DHEM data places this
intercept on the very edge of the modelled plate conductor and is
located 70m to the north of the limits of previous mining at this
level.
The intercept at 552m is a relatively narrow, but very
high-grade zone of polymetallic massive sulphides located in the
hanging wall of the B Lens and represents a new mineralised
surface. Access to this zone would utilise the same development
infrastructure for the main B Lens. The intercepts are shown
in Figure 1 along with the modelled DHEM plates. The DHEM
plates indicate potential for a mineralised zone of dimensions 250m
x 150m and extending out to the limits identified in
WNDD0105. Based on these DHEM plates and the existing
intercepts an Exploration Target can be defined of approximately
0.6Mt – 1.1Mt with grades of 7.0%ZnEq – 14%ZnEq[2]
---------------------------------------------------------------------------------------------------------------------------
[1] ZnEq % used in this release refers to the calculated Zn
equivalent grade based on the Zn, Cu, Pb, Au and Ag grades, the
formula for which is provide in Appendix 1 at the end of this
report.
[2] An Exploration Target is term used within the JORC2012 Code
for an estimate of the exploration potential of a mineral
deposit. As used in this release the stated exploration
target is based upon the parameters described in the text, however
the potential quantity and grade is conceptual in nature and there
is insufficient information to estimate a Mineral Resource and it
remains uncertain if further exploration will result in the
estimation of a Mineral Resource in this area of recent
drilling.

G2 Lens Drilling
As previously reported, five holes have been completed on the G2
Lens position targeting shallow extensions to known mineralisation
(Figures 2 and 3). The strong intercept in WNDD0106 was
reported previously (ASX/TSX 6 September 2016: 11m @ 11% ZnEq from
133m (6.3% Zn, 0.5% Cu, 3.3%Pb, 0.1g/t Au, 10g/t Ag)) and assays
have been recently received for WNDD0107 where a number of weakly
mineralised intervals were returned, with a best result of:
- 3m @ 2.9% ZnEq from 119m (1.7% Zn, 0.18% Cu, 0.11% Pb,
0.28g/t Au, 10.2g/t Ag)
The Company is awaiting assays from WNDD0109, WNDD0110 and
WNDD0111, all of which were drilled into the G Lens position.
DHEM Results G2 Lens
DHEM surveys were completed on WNDD0109 and WNDD0110 with three
conductors of interest being identified and modelled by Heron’s
consultant geophysicist. Of most interest is an off-hole
conductor located below WNDD0110 with dimensions 35m x 55m and a
conductance of 50 siemens. The conductance is suggestive of
stringer sulphide mineralisation and provides a clear target for
future drilling to extend the existing Mineral Resource in this
area. The planned decline is located adjacent to this
zone and any additional mineralisation delineated here has the
potential to impact the early production profile.

Notes: True width is an estimate of the actual thickness of the
intercept based on interpreted lens orientation (approximately 80%
to 90% of downhole width, with 80% used in this table as a general
guide); unless noted grades are weighted average grades, weighted
by length of samples intervals downhole, which are nominally 1
metre. No weighting was applied for differences in specific
gravity; * Previously reported results; ** SG weighted grades used
due to significant differences in SG of individual samples.
Zinc equivalent calculation
The zinc equivalent ZnEq calculation takes into account, mining
costs, milling costs, recoveries, payability (including transport
and refining charges) and metal prices in generating a Zinc
equivalent value for Au, Ag, Cu, Pb and Zn. ZnEq =
Zn%+Cu%*3.12+Pb%*0.81+*Au g/t*0.86+Ag g/t*0.03
Metal prices used in the calculation are: Zn US$2,300/t, Pb US$
2,050/t, Cu US$6,600/t, Au US$1,250/oz and Ag US$18/oz. It is
Heron’s view that all the metals within this formula are expected
to be recovered and sold.
JORC 2012 Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section applies to all succeeding
sections)
| Criteria |
JORC Code explanation |
Commentary |
| 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. |
· Samples from the diamond-core holes are
being taken from mostly HQ3 and NQ3 sized core and sampled on a
nominal 1 metre basis taking into account smaller sample intervals
up to geological contacts. The core is cut in half along the
core orientation line (where available) and in massive sulphide
zones one portion is quartered for assaying, half the core is
preserved for metallurgical testing and the remaining quarter is
retained as reference material in the core trays. In
non-massive sulphide material half core is sampled.· These
sampling methods are standard industry methods and are believed to
provide acceptably representative samples for the type of
mineralisation encountered. |
| Drilling techniques |
· Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and
details. |
· Diamond-core drilling is being undertaken
by Sandvik UDR650 rigs with mostly HQ3 sized core being
drilled. Various techniques are employed to ensure the hole
is kept within limits of the planned position. The core is
laid out in standard plastic cores trays. |
| Drill sample recovery |
· Method of recording and assessing core
and chip sample recoveries and results assessed. |
· The core is transported to an enclosed
core logging area and recoveries are recorded. Recoveries to
date have been better than 95%. The core is orientated where
possible and marked with 1 metre downhole intervals for logging and
sampling. |
| 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. |
· The diamond core is geologically logged
by qualified geologists. Geotechnical logging is also being
undertaken on selected sections of the core. Samples for
metallurgical testing are being kept in a freezer to reduce
oxidation prior to being transported to the metallurgical
laboratory. |
| Sub-sampling techniques and sample
preparation |
· For all sample types, the nature, quality
and appropriateness of the sample preparation technique. |
· All core samples are crushed then
pulverised in a ring pulveriser (LM5) to a nominal 90% passing 75
micron. An approximately 250g pulp sub-sample is taken from the
large sample and residual material stored. · A quartz flush
(approximately 0.5 kilogram of white, medium-grained sand) is put
through the LM5 pulveriser prior to each new batch of
samples. A number of quartz flushes are also put through the
pulveriser after each massive sulphide sample to ensure the bowl is
clean prior to the next sample being processed. A selection
of this pulverised quartz flush material is then analysed and
reported by the lab to gauge the potential level of contamination
that may be carried through from one sample to the next. |
| 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.· Nature of quality
control procedures adopted (eg standards, blanks, duplicates,
external laboratory checks) and whether acceptable levels of
accuracy (ie lack of bias) and precision have been
established. |
· Sample preparation and assaying is being
conducted through ALS Laboratories, Orange, NSW with certain final
analysis of pulps being undertaken at the ALS Laboratory in
Brisbane QLD.· Gold is determined by 30g fire assay fusion
with ICP-AES analysis to 1ppb LLD. · Other elements by mixed
acid digestion followed by ICP-AES analysis. ·
Laboratory quality control standards (blanks, standards and
duplicates) are inserted at a rate of 5 per 35 samples for ICP
work. |
| Verification of sampling and assaying |
· The verification of significant
intersections by either independent or alternative company
personnel.· Documentation of primary data, data entry
procedures, data verification, data storage (physical and
electronic) protocols.· Discuss any adjustment to assay
data. |
· An internal review of results was
undertaken by Company personnel. No independent verification
was undertaken at this stage.· All field and laboratory data
has been entered into an industry standard database using a
contract database administrator (DBA) in the Company’s Perth
office. Validation of both the field and laboratory data is
undertaken prior to final acceptance and reporting of the
data.· Quality control samples from both the Company and the
Laboratory are assessed by the DBA and reported to the Company
geologists for verification. All assay data must pass this
data verification and quality control process before being
reported. |
| 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 Resource
estimation. |
· The drill collars were initially located
with a combination of handheld GPS and licenced surveyor using a
DGPS system, with accuracy of about 1m. The final drill
collars are “picked up” by a licenced surveyor with accuracy to 1
centimetre.· While drilling is being undertaken, downhole
surveys are conducted using a downhole survey tool that records the
magnetic azimuth and dip of the hole. These recordings are
taken approximately every 30 metres downhole. Where possible
holes are also being surveyed with gyroscopic methods, with some 80
percent of holes drilled in the current program also surveyed by
this method after drilling has been completed. |
| 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 diamond drilling is mostly
following-up in various directions from previous intercepts with a
nominal spacing in the range 30-40m. This drill hole spacing
will be sufficient to provide Mineral Resource estimates in the
future. |
| 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. |
· The drilling orientation is designed to
intersect the mineralised lenses at a close to perpendicular
angle. The mineralised lenses are dipping at approximately
50-70 degrees to the west and the drilling is approximately at 60
degrees to the east. This will vary from hole to hole. |
| Sample security |
· The measures taken to ensure sample
security. |
· Samples are being secured in green
plastic bags and are being transported to the ALS laboratory in
Orange, NSW via a courier service or with Company
personnel/contractors. |
| Audits or reviews |
· The results of any audits or reviews of
sampling techniques and data. |
· A review and assessment of the laboratory
procedures was under taken by Company personnel in late 2014
resulting in some changes to their sample pulverising
procedure. |
Section
2
Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this
section.)
| 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. |
· The Woodlawn project is located 200km
south-west of Sydney in the state of New South Wales. The
area is near the top of the Great Australian Dividing range and has
an elevation around 800m above sea-level. The mineral and
mining rights to the project are owned 100% by the Company through
the granted, special (Crown and Private Land) mining lease 20
(SML20). The lease has been renewed to the 16 November
2029.· The project area is on private land owned by Veolia
who operate a waste disposal facility that utilises the historical
open-pit void. An agreement is in place with Veolia for the
Company to purchase certain sections of this private land to
facilitate future mining and processing activities. A
cooperation agreement is also in place between Veolia and the
Company that covers drilling and other exploration activities in
the area. |
| Exploration done by other parties |
· Acknowledgment and appraisal of
exploration by other parties. |
· The Woodlawn deposit was discovered by
the Jododex JV in 1970 and open-pit mining began in 1978 and
continued through to 1987. The project was bought outright by Rio
Tinto Ltd (CRA) in 1984 who completed the open-pit mining.
Underground operations commenced in 1986 and the project was sold
to Denehurst Ltd in 1987 who continued underground mining up until
1998. The mineral rights to the project were then acquired by
TriAusMin Ltd in 1999 who conducted studies on a tailings
re-treatment process and further underground operations.
Heron took 100% ownership of the project in August 2014 following
the merger of the two companies. Some 980 surface and
underground drill holes have been completed on the project to date
and various studies undertaken. |
| Geology |
· Deposit type, geological setting and
style of mineralization. |
· The Woodlawn deposit comprises
volcanogenic massive sulphide mineralisation consisting of
stratabound lenses of pyrite, sphalerite, galena and
chalcopyrite. The mineralisation is hosted in the Silurian
aged Woodlawn Felsic Volcanic package of the Goulburn sub-basin on
the eastern side of the Lachlan Fold Belt. |
| Drill hole Information |
o 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: |
· A table detailing the drill hole
information is given in the body of the report. |
| 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 reported assays are weighted for
their assay interval width. The majority of the assay interval
widths are 1 metre, but this weighting does take into account the
non 1 metre intervals and weights the average assay results
accordingly.· For the results reported here no weighting was
included for specific gravity (SG) measurements that have been
taken for all sample intervals as the samples within the intervals
are of a similar SG. |
| Relationship between mineralization 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. |
· The massive sulphide zone intercepted in
the drilling to date is at an angle to the drill axis and therefore
the true width is estimated to be some 0.8 of down-hole
width. That is, a down-hole intercept of 16m equates to a
true width of 12m. This is only an approximation at this
stage and will be better estimated as the orientation of the Lenses
is better defined. |
| 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. |
· Where relevant, a diagram showing the
hole positions relevant for current phase of exploration is
included in the release. Other maps and diagrams showing the
location of the Woodlawn Project are included in other recent
Company releases. |
| 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 Results. |
· The reporting is considered to be
balanced and all relevant results have been disclosed for this
current phase of exploration. |
| 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 drill holes are being cased with
either 40 or 50 millimetre PVC tubing for down-hole DHEM surveying

large-scale step-out drilling). |
· The third phase of drilling at Woodlawn
commenced in July 2016 and was completed in early September 2016
with 8 diamond holes for 2,527m drilled. The program was designed
to test step-out exploration targets focussing on the northern
extensions to the B Lens horizon. In addition, a number of
holes were planned to in-fill and close out shallow mineralised
positions to better define the Mineral Reserves for the early part
years of the production schedule.· The results of the program
will be assessed prior to further work commencing, however, it is
clear a number of shallow targets may warrant additional drilling
to generate shallow Mineral Reserves. |
