Edna Beryl Small Mine Update

  • Pre development shallow underground drilling at Edna Beryl intersects bonanza gold within the supergene hematite ironstone of:

1.83m @ 139.7 g/t gold from drill hole A

1.83m @ 309.5 g/t gold from drill hole B

1.83m @ 93.4 g/t gold from drill hole C

  • All holes ended in mineralisation due to drilling limitations and results may not be representative of the ore body

  • Small Mines strategy to deliver a risk-free, near term income stream

  • Production and ventilation shafts refurbished with all infrastructure and services established, including 8 person camp

  • Final soil testing completed and evaporation pond design well underway.

  • Permitting being finalised ahead of mining

  • Planning underway to bring forward development of additional small mines, plus potential development of the high grade Chariot Mine

Emmerson Resources Limited (“Emmerson”, ASX: ERM) and partner, Evolution Mining Limited (“Evolution”, EVN) are pleased to provide a progress report on the first of the “small mines” at Edna Beryl, within Emmerson’s 100% owned project at Tennant Creek in the Northern Territory.

The “small mines” Tribute Agreement struck with the Edna Beryl Mining Company (EBMC) in 2015 (ASX: 11 Aug 2015) and subject to regulatory approval, allow EBMC to commence mining of the highgrade Edna Beryl gold deposit (Fig 1).

This standalone Tribute Agreement provides Emmerson with a number of advantages:

  • A risk- free, near term income stream from its non-core assets via a royalty agreement (until EVN completes its earn-in, ERM receives 100% of its share flowing from this agreement)

  • Future access to refurbished underground workings for near mine exploration,

  • The opportunity to monetise a pipeline of other non-core assets within Emmerson’s extensive tenement holdings,

The refurbishment of the production shaft to 54m and the ventilation shaft to 26m (Figures 2 & 3) at Edna Beryl is now complete. This refurbishment has included re-establishment of an east-west - drive that was developed in April, 2004 by Edna Beryl Mining Company (formally Craig’s Mining Services). The drive successfully intersected the upper gold pod (in 2004) and provided a 209 tonne, bulk sample for the previous owner, Giants Reef Mining Limited (GRM). The bulk sample was treated through the Warrego CIP mill and returned an exceptional head grade of 58.4 grams per tonne gold. Development of Edna Beryl was halted in 2005 as the contractor was redirected onto other projects.

The now refurbished cross cut drive has provided access to the top of the hematite ironstone and pre development drilling has now confirmed the exceptional grades associated with the first samples (Table 1 & 2). All three holes ended in mineralised hematite ironstone so true thickness cannot be confirmed.

Based on this new information it is now believed that the bulk sample collected in 2004 represented mineralisation within the alteration envelope at the very top of the gold pod and that these drill holes are the first samples of the main supergene zone within the hematite ironstone. When commissioned Edna Beryl will, to the company’s knowledge become the highest grade gold mine in Australia.

About Tennant Creek and Emmerson Resources

The Tennant Creek Mineral Field (TCMF) is one of Australia’s highest grade gold and copper fields producing over 5.5 Mozs of gold and 470,000 tonnes of copper from a variety of deposits including Gecko, Orlando, Warrego, White Devil, Chariot and Golden Forty, all of which are within Emmerson Resources (ASX: ERM) exploration and joint venture portfolio. These deposits are considered to be highly valuable exploration targets and, utilising modern exploration techniques, Emmerson has been successful in discovering copper and gold mineralisation at Goanna and Monitor in late 2011, the first discoveries in the TCMF for over a decade. To date, Emmerson has only covered 5.5% of the total tenement package (in area) with these innovative exploration techniques and is confident that, with further exploration, more such discoveries will be made.

Emmerson holds 2,500km[2] of ground in the TCMF, owns the only gold mill in the region and holds a substantial geological database plus extensive infrastructure and equipment. Emmerson has consolidated 95% of the highly prospective TCMF where only 8% of the historical drilling has penetrated below 150m.

Emmerson is led by a board and management group of experienced Australian mining executives including former MIM and WMC mining executive Andrew McIlwain as non-executive chairman, and former senior BHP Billiton and WMC executive Rob Bills as Managing Director and CEO.

Pursuant to the Farm-in agreement entered into with Evolution Mining Limited (Evolution) on 11 June 2014, Evolution is continuing to sole fund exploration expenditure of $15 million over three years to earn a 65% interest (Stage 1 Farm-in) in Emmerson’s tenement holdings in the TCMF. An option to spend a further $10 million minimum, sole funded by Evolution over two years following the Stage 1 Farm-in, would enable Evolution to earn an additional 10% (Stage 2 Farm-in) of the tenement holdings. Evolution must spend a minimum of $7.5 million on exploration, before it can terminate the farm-in. Emmerson is acting as manager during the Stage 1 Farm-in and is receiving a management fee during this period. Exploration expenditure attributable to the Stage 1 Farm-in to date is approximately $8 million.

About Evolution Mining

Evolution Mining is a leading, growth-focussed Australian gold miner. Evolution operates seven wholly owned mines – Cowal in New South Wales, Cracow, Mt Carlton, Mt Rawdon and Pajingo in Queensland, and Edna May and Mungari in Western Australia.

Group production for FY15 from Evolution’s five existing operating assets (prior to completion of the Cowal and Mungari acquisitions) totalled 437,570 ounces gold equivalent at an All-In Sustaining Cost of A$1,036 per ounce. Evolution has guided FY16 attributable gold production from all seven operating assets of 770,000 – 820,000 ounces at an AISC of A$970 – A$1,020 per ounce.

About Edna Beryl Mineralisation

Edna Beryl was discovered by prospectors in 1935 and mined underground in the 1940s and 1950s to a maximum depth of approximately 50 metres. Production up until 1952 was reportedly 2,700t of ore at an exceptional grade of 53g/t gold.

More recent exploration in the Edna Beryl area between 1996 and 2000 by Giants Reef Mining GRM outlined additional high-grade gold mineralisation below the historic workings and resulted in an estimate being reported in 1998 by independent consultants in accordance with the Australasian Code for Reporting of Identified Mineral Resources and Ore Reserves (JORC:1998). While this estimate does not meet the minimum reporting requirements for a Mineral Resource under the current 2012 JORC Code, Emmerson considers the Edna Beryl mineralisation to constitute an Exploration Target of 5,000t to 10,000t at 20 to 30 g/t gold, however cautions that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource and that it is uncertain if further exploration will result in the estimation of a Mineral Resource.

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 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

disclosure of detailed information.
Air Leg samples were collected from the floor of
the refurbished cross cut drive at Edna Beryl to
a final depth of 1.83m or 6 foot.
Samples were collected from approximately
53m below surface level.
Samples consisted of powdered (dust) and
larger chips of red hematite ironstone.
 The Edna Beryl Exploration Target has been
sampled using RAB, Reverse Circulation (RC) and
diamond drilling (DD) techniques. 24 RAB holes
for 1,140m, 29 RC/Percussion holes for 2,534m
and 26 Diamond holes for 4,678.2m have been
completed. The drill hole spacing is nominal
10m x 10m grid spacing. In areas of
mineralisation spacing has been reduced to 5m x
5m. Holes have been angled to optimally test
the host shear zone. Typically, most drill holes
have been drilled towards the North at angles
(dip) between 45 to 70 degrees from surface.
 RAB samples consist of 4m composites which
may
have
suffered
from
down-hole
contamination and were not used in any
resource estimation. Only RC and Diamond data
was used for resource estimations which
included 55 holes and 2,373 samples.
 RC chips are riffle split on site to obtain 3m
composite samples from which 2.5 – 3.0kg was
pulverised (at the laboratory) to produce a 50g
charge for analysis by multi acid digest with an
AAS (Cu,Fe,Bi) finish & Fire Assay (Au) finish.
 Individual 1m samples were pulverised (at the
laboratory) to produce a 50g charge for analysis
by multi acid digest with an AAS (Cu,Fe,Bi) finish
& Fire Assay (Au) finish.
 RC samples were collected via a fixed splitter
that is mounted to the drill rig. Samples were
manually split a second time by field assistants.

Diamond core was used to obtain high quality
samples that were logged for lithological,
structural, geotechnical, density and other
attributes.

No assessment of the QC of drill hole sampling
methods, after cut by the drill rig can be made
from available data, hence the author has to
assume no significant errors occurred during or
post drilling sampling process. QAQC measures
are assumed to be asper industrybestpractice

Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg 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).
Three vertical air leg holes were spaced at 1m x
1m and drilled to a final depth of 1.83m.
The diameter of the air leg drill steel outside
diameter is 30mm.
Two samples were collected from each drill
hole.
The first sample was collected from the surface
of the drive floor to a distance of 1.22m or 4
foot.
The 1.22m hole was then blown out and
cleaned via the air leg to ensure minimal
contamination.
The second sample was then collected from
1.22 to a final depth of 1.83m or 6 foot.
All three holes were drilled this way.

Results were faxed directly to Mr Kevin Craig.
Digital data was emailed to the Exploration
Manager.
Samples were placed in sealed polyweave bags
and larger bulka bags for transport to the assay
laboratory (Pine Creek).
The assay laboratory confirms that all samples
have been received and that no damage has
occurred during transport.
Results data was faxed to the Exploration
Manager of Giants Reef and also emailed to the
Project geologist.
While samples are being processed in the Lab
theyare considered to be secure.

 Edna Beryl was discovered in 1935 and mined in
the 1940s and 1950s by excavation of vertical
shafts and horizontal drives to a maximum depth
of about 50 metres. Production up until 1952
was reportedly 2,700 tonnes of ore at an
average grade of 53 grams gold per tonne.
 Giants Reef Mining conducted all known
“modern” exploration in and around the Edna

Beryl Exploration Target Area.
 Giants Reef has carried out exploration on the
Edna Beryl area from 1990 to 2005 and during
this
time
identified
significant
gold
mineralisation below the original workings.
 An existing shaft sunk during the earlier mining
was refurbished in 1996.
 In 2004 – 2005 mining was conducted by the
Edna Beryl Mining Company (formally known as
Craig’s
Mining
Services)
in
a
Tribute
arrangement
with
Giants
Reef
Mining.
Approximately 410 ounces was produced during
this period from the upper mineralised pod from
an exploration shaft and drive to current depth
of 52m.
 Influx of underground water plus declining gold
price ceased the operation in July 2005.
Geology Deposit type, geological setting and
style of mineralisation.
 Gold and copper-gold deposits discovered in the
Tennant Creek gold field to date, are hosted in
the Lower Proterozoic Warramunga Formation; a
metamorphosed (greenschist facies) greywacke-
siltstone-shale
sedimentary
sequence,
that
usually
displays
a
pronounced
east-west
cleavage. Ore occurs adjacent to steeply
dipping,
lenticular
or
pipe-like
magnetite/haematite/chlorite/quartz
bodies
(‘ironstone’) that are found along east-west
trending structures. It is generally thought that
the magnetite/haematite was hydrothermally
formed in dilation zones along the controlling
structures, and that the deposition of gold,
sulphides and associated alteration minerals was
a later event with mineralisation possibly being
derived from a different source but following the
same structurally controlled path. In plan view,
the ironstone bodies tend to be narrowest in the
north-south direction and elongated east west,
reflecting the regional cleavage and shearing.
Edna Beryl clearly follows this pattern. Their
vertical dimensions may run to hundreds of
metres, beyond the reach of surface drilling. Ore
grades may occur over substantial vertical
intervals of an ironstone pipe or lens, but are not
expected to occur over the entire length.
 The mineralisation style is considered to be Iron
Oxide Copper Gold.
 Supergene enrichment is very evident.

truncations (eg cutting of high grades)
and cut-off grades are usually Material
and should be stated.
Where

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.
 Mineralized RC and Diamond intersections are
reported as down hole intervals and not
weighted averages.
 The results discussed are exploration results only
and no allowance is made for recovery losses
that may occur should mining eventually result,
nor metallurgical flow sheet considerations.
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 drillhole angle is
known, its nature should be reported.
If it is not known and only the downhole
lengths are reported, there should be a
clear statement to this effect (eg
‘downhole length, true width not
_known’). _
 The holes drilled within the Edna Beryl
Exploration Target area are perpendicular the
east-west striking mineralised zone. The holes
were designed and drilled perpendicular to the
steep dipping mineralised zone making the
intercepts approximate to true width.
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 drillhole collar locations and
appropriate sectional views.
 Refer to Figures in body of text.
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.
• Due to the age of this Resource estimation,
Emmerson are cautious and do not believe the
historical Resource estimate can be reported in
accordance with the current 2012 JORC Code.
Emmerson considers the Edna Beryl mineralisation
to be an Exploration Target.
It is uncertain that followingevaluation and/or

will be able to be reported as Mineral Resources or
Ore Reserves in accordance with the requirements in
Appendix 5A (JORC Code).
Other

Other exploration data, if meaningful
and material, should be reported
including (but not limited to): geological
observations;

 Geotechnical logging was carried out on all
diamond drill holes for recovery, RQD and
number of defects (per interval). Information on
structure type, dip, dip direction, alpha angle,
beta angle, texture, shape, roughness and fill
material was stored in the structure table of the
Micromine database.
 Density measurements were collected by Giants
Reef geologists.
 Metallurgical testing of selected mineralised
Edna Beryl samples was conducted by Metcon
Laboratories Pty Ltd in 1996.
 Metallurgical testing concluded that 70% could
be gravity recovered with the remaining gold
cyanide soluble so that total gold extraction of
>98% could be obtained. Screen Fire Assay of
selected samples was conducted by Giants Reef
Mining.
 Geophysical magnetic susceptibility logging is
completed at 1m intervals on site (RC drilling)
and in the core shed for selected sections of
diamond core.
 Thin section samples were collected by Giants
Reef Mining to assist in the refinement of the
geological 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).

 Once the underground development has been
established, Emmerson plan to conduct a small
underground diamond drilling program searching
for lateral and down dip continuance of the
known mineralisation.
 Several other exploration targets are proximal to
the Edna Beryl exploration target and data is
currently being reviewed.
 It is likely that additional surface drilling will
occur
