Heron Resources Limited (ASX:HRR TSX:HER, “Heron” or the
“Company”) is pleased to provide further assay 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 shallow
intercepts in the G2 Lens hanging-wall zone:-
- 8m @ 28% ZnEq[1] from 107m (8.7% Zn,
0.5% Cu, 5.2% Pb, 4.0g/t Au, 326g/t Ag) WNDD0110
- Including 3.7m @ 56% ZnEq (18.7% Zn, 1.2% Cu, 10.0% Pb,
6.9g/t Au, 650g/t Ag) WNDD0110
- 0m @ 10% ZnEq from 140m (7.9% Zn, 0.2% Cu, 0.7% Pb,
0.2g/t Au, 13g/t Ag) WNDD0110
- 9m @ 9% ZnEq from 160m (5.1% Zn, 0.3% Cu, 2.8% Pb,
0.5g/t Au, 11g/t Ag) WNDD0111
- Intercepts represents a significant new high-grade
discovery in the hanging-wall of the G2 Lens position
- Shallow position provides important potential early
production benefits for the underground project
- Drill program continues to demonstrate the Woodlawn
mineral system remains open to north-west and south
A program of eight diamond holes for 2,527m was completed in
early September 2016, targeting extensions to the B Lens at depth
and a number of positions around the shallow G2 Lens to add to the
early mine inventory. Final assay results for this drilling
have now been received.
Commenting on these latest results, Heron Resources Managing
Director and CEO, Mr Wayne Taylor, said:
“The zones targeted in this drilling program represent only a
small number of the open positions that exist within this extensive
mineral system and we are extremely pleased with the results.
Notably, they provide evidence that Woodlawn remains open both to
the south and north-west. This campaign has been very successful in
demonstrating the expansion potential that exists with the delivery
of an extension to the B Lens to the north-west, extensions to the
shallow G2 Lens south and now the discovery of a high-grade
hanging-wall position in the G2 Lens at shallow depth. In addition
the very high precious metal content in the hanging-wall is a
unique feature to this stratigraphic horizon and remains open in a
number of directions.”
G2 Lens Drilling
The G2 Lens is located to the south of the Kate Lens, and
adjacent to the planned route of the decline between 100-200m below
the surface. Recent drilling has targeted this area for its
ability to add immediately to the early mine inventory. New
assay results for this area include:
- 8m @ 28% ZnEq from 107m (8.7% Zn, 0.5% Cu, 5.2% Pb,
4.0g/t Au, 326g/t Ag) WNDD0110
- Including 3.7m @ 56% ZnEq% (18.7% Zn, 1.2% Cu, 10.0%
Pb, 6.9g/t Au, 650g/t Ag) WNDD0110
- 0m @ 10% ZnEq from 140m (7.9% Zn, 0.2% Cu, 0.7% Pb,
0.2g/t Au, 13g/t Ag) WNDD0110
- 9m @ 9% ZnEq from 160m (5.1% Zn, 0.3% Cu, 2.8% Pb,
0.5g/t Au, 11g/t Ag) WNDD0111
The G2 mineralisation typically consists of stringer zinc
sulphides (sphalerite) with lesser lead and copper sulphides.
However, the upper intercept in WNDD0110 is more typical high-grade
polymetallic sulphides (Figure 1) within a broad shallow dipping
mineralised envelope that contains the other intercepts (Figures 2
and 3). This represents a new zone of high-grade mineralisation and
demonstrates again the discovery potential of the Woodlawn system,
in this case, in the sparsely drilled south-western sector.
Due to the very high sphalerite content of the high-grade
sulphides, this zone returned a weak down hole electro-magnetic
(DHEM) response (sphalerite has very low conductivity) and so at
this stage without further drilling the size of this high-grade
zone is poorly constrained. This high-grade sphalerite
occurrence with weak DHEM response may have implications for other
areas of prior work. Interestingly, the intercept has some of the
highest gold and silver grades recorded at Woodlawn and is
representative of a well-defined zone of precious metal enrichment
at the G2 Lens hanging-wall contact.
The lower intercept (from 140m) in WNDD0110 is more typical G2
Lens stringer sphalerite and is associated with an off-hole EM
conductor below the hole (Figure 3) which provides a clear target
for future drilling. The intercept in WNNDD0111 is in the
plane of the main G2 Lens and provides for continuity of the lens
in the down-dip direction.
Interpretation
The drilling program has expanded the strike extent of the
Woodlawn mineral system and results demonstrate that it remains
open both to the south and the north-west. This is significant in
expanding the lateral footprint from which to make further
discoveries and potentially draw new mine production from. Both the
B Lens north and G2 Lens positions can be serviced by existing
planned capital development as contemplated in the Woodlawn
Feasibility Study providing areas for leveraged additions to the
mine inventory.
The Company is continuing to work on defining the next phase of
work to follow-up these results.

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
which is undertaken on the majority of the holes drilled.·
Geotechnical logging is undertaken on all core, 25m either side of
the massive sulphide lenses.· Archimedes method SG
measurements are determined for all sampled intervals. |
Further work |
· The nature and scale of planned further
work (eg tests for lateral extensions or depth extensions or
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 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
fully assessed prior to further work commencing. |
